DIMENSIONS OF PERSONALITY AND PERSONALITY PATHOLOGY: FACTOR STRUCTURE OF THE SHEDLER–WESTEN ASSESSMENT PROCEDURE-II (SWAP-II)

Researchers have proposed replacing the current system for diagnosing personality disorders with a dimensional trait model. Proposed trait models have been derived primarily from data provided by untrained lay informants (often via self-report questionnaires) using item sets de-rived from lay conceptions of personality. An alternative is to derive personality trait dimensions from data provided by clinically expert in-formants using an instrument that includes personality features sa-lient to clinicians who treat personality dysfunction. The authors report the factor structure of the latest edition of the Shedler–Westen Assess-ment Procedure (SWAP-II) using a normative clinical sample of 1,201 North American patients assessed by experienced psychologists and psychiatrists. Factor analysis identified 14 clinically and empirically coherent factors. The findings highlight dimensions of personality and personality pathology that have not emerged in personality item sets designed for lay personality description.

Dimensional personality diagnosis has substantial advantages over cate-gorical diagnosis, at least for research purposes (Krueger, Watson, & Bar-low, 2005; Westen, Gabbard, & Blagov, 2006; Widiger & Samuel, 2005). Some investigators equate the term “dimensional” with trait models derived via factor analysis. However, trait models represent only one of several al-ternative approaches to dimensional personality diagnosis.

One approach to dimensional diagnosis is simply to dimensionalize ex-isting DSM-IV personality disorders. This can be accomplished by sum-

ming the number of diagnostic criteria met for each disorder (instead of imposing an arbitrary cut-point; Oldham & Skodol, 2000). It can also be accomplished via a prototype matching procedure, whereby diagnosti-cians gauge the similarity or “fit” between a patient’s clinical presentation and a paragraph-length narrative description of each disorder (Rottman, Ahn, Sanislow, & Kim, 2009; Spitzer, First, Shedler, Westen, & Skodol, 2008; Westen & Shedler, 2000; Westen, Shedler, & Bradley, 2006). Else-where, we have proposed a dimensional approach to personality diagnosis based on empirically derived personality prototypes (Westen & Shedler, 1999a, 1999b; Westen, Shedler, Bradley, & DeFife, 2012). This diagnostic system preserves a syndromal approach to personality, consistent with all editions of DSM to date; however, both the diagnostic groupings and the descriptions of the diagnoses are derived empirically and reflect naturally occurring groupings in the clinical population.

The classification systems just described are person-centered and syn-dromal. That is, they focus on personality syndromes, or multifaceted constellations of interrelated personality features. A very different ap-proach to dimensional diagnosis is variable-centered, focusing on discrete trait dimensions (rather than multidimensional syndromes) derived via factor analysis (e.g., Krueger & Markon, 2011; Krueger, Watson, & Barlow, 2005; Widiger, Simonsen, Krueger, Livesley, & Verheul, 2005). For several years, trait psychologists have advocated moving away from the syndro-mal approach of DSM-IV to a diagnostic system based on the five factor model (FFM) (e.g., Widiger, Costa, & McCrae, 2002). Investigators have also proposed that both normal and pathological personality can be un-derstood in terms of a trait model comprising four superordinate factors, variously described as (1) negative affectivity or neuroticism, (2) introver-sion or low positive affectivity, (3) antagonism or low agreeableness, and (4) impulsivity or low conscientiousness (Livesley, Jang, & Vernon, 1998; Watson, Clark, & Harkness, 1994; Widiger & Simonsen, 2005).

The FFM and derivative models proposed as taxonomic alternatives to the syndromal diagnoses of DSM-IV (Widiger & Trull, 2007) have a number of advantages, perhaps most importantly that FFM factors tend to repli-cate across multiple methods and informants and reliably capture impor-tant aspects of normal personality. A potential limitation is that the re-search underlying these models (Clark, Livesley, Schroeder, & Irish, 1996; Markon, Krueger, & Watson, 2005) (including the new variant proposed by the DSM-5 Axis II Work Group; http://www.dsm5.org) has relied heavily on self-report questionnaire data. This presupposes that (a) the data nec-essary and sufficient to derive a comprehensive and clinically relevant model of personality do not require expertise in psychopathology; (b) indi-viduals with significant personality pathology have sufficient self-aware-ness and insight that their self-reports (or those of untrained peer observ-ers) are sufficient to derive a comprehensive model of personality and its pathology; and (c) that the language of lay observation (or attempts to summarize it via factor analysis) is adequate for a diagnostic manual in-

tended to be useful to both clinical practitioners and psychopathology re-searchers.

Both meta-analytic investigations (Klonsky, Oltmanns, & Turkheimer, 2002) and data from recent large-N studies (Clifton, Turkheimer, & Olt-manns, 2005) have shown that self-reported pathological personality traits correlate only moderately (in meta-analytic research, r = .36) with the same traits assessed by lay informants and weakly with longitudinal evaluation by experts using all available data (Klein, Ouimette, Kelly, Fer-ro, & Riso, 1994; Pilkonis, Heape, Ruddy, & Serrao, 1991). By contrast, both traits and dimensional personality disorder diagnoses derived from data provided by experienced clinicians using a systematic clinical re-search interview correlate in the range of r = .50 to .70 with the same vari-ables as assessed by treating clinicians (Westen & Muderrisoglu, 2003, 2006; Westen et al., 2012). Similarly, research on “illusory mental health” (Shedler, Mayman, & Manis, 1993) demonstrates that self-report mea-sures of neuroticism (or negative affectivity) cannot distinguish psycho-logically healthy individuals from psychologically distressed individuals who lack self-awareness.

Whether superior in some respects or simply complementary to self- reports, quantified judgments made by clinically trained and experienced observers offer an alternative source of data for personality research, par-ticularly for developing dimensional personality diagnoses intended to be useful in clinical as well as research contexts (Shedler & Westen, 2007; Westen & Shedler, 2007). Although much of our research to date using expert observers has focused on personality disorder prototypes (i.e., con-stellations of interrelated characteristics that together comprise a diag-nostic syndrome), we have also developed dimensional trait models in both adult (Shedler & Westen, 2004a) and adolescent (Westen, Dutra, & Shedler, 2005) samples by factor analyzing adult and adolescent versions of the Shedler–Westen Assessment Procedure (SWAP). This article focuses on trait dimensions derived via factor analysis of the current version of the adult SWAP instrument.

The SWAP-200 (and its revised version, the SWAP-II) is a comprehensive set of 200 items capturing both personality pathology and aspects of adap-tive personality functioning. A mental health professional with a thorough knowledge of the patient based on clinical examination ranks each item from 7 (highly descriptive) to 0 (not descriptive). The assessor must have first become familiar with the patient, specifically in a professional clini-cal-evaluative context through a comprehensive research-clinical inter-view (the Clinical Diagnostic Interview; see Westen & Muderrisoglu, 2003; www.psychsystems.net/manuals) or a minimum of six clinical hours of assessment and treatment. The instrument is thus designed specifically for use by clinical professionals functioning in professional contexts. The instrument is based on the Q-sort method: To maximize reliability and as-sure comparability of scores across assessors, assessors rank-order the personality-descriptive statements using a fixed distribution (in which

284 WESTEN ET AL.

relatively few items receive the highest ranks, and progressively more items receive lower ranks, mirroring the natural distribution of psycho-pathological variables).

SWAP data can be analyzed via conventional factor analysis (a variable-centered approach) to identify underlying personality factors or trait di-mensions. They can also be analyzed via Q-factor analysis (a person-cen-tered approach) to identify groupings of patients who share a common personality syndrome (i.e., who are psychologically similar to one another and distinct from patients in other groupings). Thus, the SWAP instru-ments can be used to derive both (a) trait dimensions and (b) naturally occurring diagnostic grouping in the clinical population (i.e., diagnostic prototypes; Westen & Shedler, 1999b; Westen et al., 2012). Because the item sets for both adult and adolescent versions of the SWAP cover the domains included in DSM-III-R and DSM-IV, the instruments can addition-ally be used to derive (dimensional) DSM Axis II diagnoses.1

Factor analyses of the SWAP-200 (the prior adult version of the instru-ment) yielded 12 conceptually coherent and clinically relevant factors (Shedler & Westen, 2004a), including Psychological Health, Psychopathy, Emotional Dysregulation, Dysphoria, Obsessionality, Thought Disorder, Sexual Conflict, and Histrionic Sexualization. Factor analysis of the SWAP-200-A (the adolescent version of the instrument) yielded 11 highly similar factors, although it also included some factors distinct to this develop-mental period (e.g., Delinquent Behavior, Attentional Dysregulation, and Peer Rejection). These SWAP factors (both adult and adolescent) showed expected patterns of correlations with a wide range of criterion variables, providing support for their construct validity. Efforts to identify higher-order factors by factor analyzing the factors did not yield coherent or in-terpretable higher-order factors, suggesting that the SWAP factors mea-sured distinct constructs that were not reducible to FFM domains.

The major limitations of our prior factor-analytic studies using the SWAP-200 were sample size and representativeness. The largest sample used to derive personality traits was 530, and the sample was selected deliberately to include only patients with diagnosable DSM-IV personality disorders in relatively equal numbers. How sample selection may have influenced or biased the factors that emerged is unclear. The current study addresses these limitations.

We report on the factor structure underlying comprehensive personality descriptions of adult patients provided by experienced clinician-observers. Each clinician-observer described one randomly selected patient in his or her care who had any degree of personality impairment or dysfunction, irrespective of whether the patient did or did not meet criteria for a DSM personality disorder diagnosis. The clinician-observers described the pa-

Whereas the original presentations of the SWAP emphasized configural diagnosis, that is, DSM-IV diagnosis and empirical derived prototypes (Westen & Shedler, 1999a, 1999b), later research has taken the more agnostic, empirical approach we describe here, namely one that makes use of whatever data-analytic and conceptual approach or approaches prove most empirically valid and clinically useful (Shedler & Westen, 2004b; Westen & Shedler, 2007).

tients using the most recent version the adult SWAP instrument, the SWAP-II. The study used a normative sample of 1,201 North American patients and was specifically designed to develop alternative taxonomic approaches to personality diagnosis for DSM-5.

METHODSAMPLE

We used the national membership rosters of the American Psychological Association and Psychiatric Association to invite a random sample of psy-chiatrists and psychologists with at least 5 years of experience postresi-dency (MDs) or postlicensure (PhDs) to provide assessment data. The re-sponse rate was more than 30%. There were no differences on any demographic or other variables we examined between participants who responded to our initial invitation and those who responded to a subse-quent follow-up invitation, suggesting that any sampling bias had mini-mal effects on results. The participating clinician-assessors received a consulting fee of $200 to complete all research forms and instruments, which required approximately 2 hours.

We asked the clinician-observers to describe “an adult patient you are currently treating or evaluating who has enduring patterns of thoughts, feeling, motivation or behavior—that is, personality problems—that cause distress or dysfunction.” To obtain a broad range of personality pathology, we emphasized that patients need not have a personality disorder diagno-sis. Patients had to meet the following additional inclusion criteria: ≥18 years of age, not in a current psychotic episode, and known well by the observer (using the guideline of ≥6 clinical contact hours but ≤2 years to minimize confounds imposed by personality change during treatment). To obtain a representative sample free from selection bias, we directed clini-cian-assessors to consult their calendars and select the last patient they saw during the previous week who met study criteria. In prior research, assessors reported that they followed these instructions as directed (e.g., Westen & Shedler, 1999a). To verify that this was the case in the present study, we recontacted a randomly selected group of 100 of the clinician-assessors who had provided data. Of the 46 who responded, 96% reported following the procedure as specified. Each assessor contributed data on one patient only (to minimize rater-dependent variance). Assessors had the option of providing SWAP-II data using a traditional card-sorting pro-cedure (with items printed on index cards) or providing SWAP-II data on-line using a secure Internet site.

MEASURES

The Clinical Data Form (CDF) is a set of objective clinician-report ratings of variables relevant to demographics, diagnosis, adaptive functioning, de-velopmental and family history, and etiology (Westen & Shedler, 1999a)

286 WESTEN ET AL.

with which clinically trained observers who have worked with a patient over a number of hours are usually familiar (e.g., history of foster care, family history of criminality). In prior studies, these ratings predicted the-oretically relevant criterion variables and reflected reasonable (and con-servative) decision rules (e.g., Russ, Heim, & Westen, 2003; Wilkinson & Westen, 2000) (e.g., clinicians followed our instructions to report adverse childhood events such as abuse or history of psychiatric hospitalizations to be present only if they had substantial data supporting them, such as corroboration from informants at the time of abuse or psychiatric records). In what follows, aside from demographics and treatment characteristics, we report ratings of adaptive functioning from the CDF using the Global Assessment of Functioning (GAF) scale from the DSM-IV Axis V. Recent research has shown that these clinician-rated variables correlate strongly with independent assessments of the same variables (DeFife, Drill, Na-kash, & Westen, 2010).

The SWAP-II is the latest revision of the Shedler–Westen Assessment Procedure, which has been used in numerous taxonomic studies (e.g., Shedler & Westen, 2004a, 2004b; Westen & Shedler, 1999a, 1999b, 2007). To describe a patient, a clinically experienced observer sorts 200 person-ality-descriptive statements into eight categories, from least descriptive of the patient (assigned a value of 0) to most descriptive (7). The instrument is based on the Q-sort method, which requires observers to arrange items into a fixed distribution. The psychometric advantages of the Q-sort meth-od were described by Block (1978).

The SWAP-II allows clinically trained observers to provide systematic and quantifiable in-depth psychological descriptions of patients using a standard “vocabulary” of personality-descriptive statements. The state-ments are written without jargon in a manner that stays close to the ob-servational data (e.g., “Tends to get into power struggles”; “Is capable of sustaining meaningful relationships characterized by genuine intimacy and caring”). Statements that require inference about internal psychologi-cal processes are written in clear, unambiguous language (e.g., “Tends to see own unacceptable feelings or impulses in other people instead of in him/herself”). The use of jargon-free language minimizes unreliable inter-pretive leaps and makes the item set useful to clinicians of all theoretical perspectives.

The SWAP-II item was designed to subsume Axis II criteria included in DSM-III through DSM-IV, including their appendices. Additionally, it incor-porates selected Axis I criteria relevant to personality (e.g., anxiety and depression), important personality constructs described in the clinical and research literatures over the past 50 years, and clinical observations from pilot studies. The SWAP-200 item set was the product of a 7-year it-erative item revision process that incorporated the feedback of hundreds of clinician-consultants who used earlier versions of the item set to de-scribe their patients. We asked each consultant: “Were you able to describe the things you consider psychologically important about your patient?” We added, rewrote, and revised items based on the feedback, then asked new

FACTOR STRUCTURE OF THE SWAP-II 287

consultants to describe new patients. We repeated this process over many iterations until most consultants answered “yes” most of the time.

The SWAP-II incorporates the additional feedback of over 2,000 clini-cian-consultants of all theoretical orientations. We edited items for clarity and added new item content where feedback indicated omission of rele-vant personality constructs. For example, the burgeoning literature on harm-avoidance (Pezawas et al., 2005) suggested that the SWAP-200 did not adequately cover the construct, so we added an item to address it di-rectly (“Decisions and actions are unduly influenced by efforts to avoid perceived dangers; is more concerned with avoiding harm than pursuing desires”). We also conducted item analyses of SWAP-200 items and deleted items that did not discriminate among patients in a national sample (i.e., that showed minimal variance across patients), and deleted or combined items where analyses indicated empirical redundancy. Overall, 23 items had significant content alterations from the SWAP-200 to the SWAP-II, and additional items were edited to clarify existing content. We have described the revision process and its outcome in additional detail in a prior publi-cation (Westen & Shedler, 2007).

An increasing body of research supports the validity and reliability of the adult and adolescent versions of the SWAP in predicting a wide range of criterion variables including, for example, suicide attempts, history of psychiatric hospitalizations, adaptive functioning, interview diagnoses, psychiatric disorders in first- and second-degree biological relatives, and developmental and family history variables (see reviews in Shedler & Westen, 2007; Westen & Shedler, 2007; Westen et al., 2012).

Axis II Checklist. To maximize accuracy of DSM-IV personality disorder diagnoses, we presented clinician-consultants with a randomly ordered checklist of the criteria for all Axis II personality disorders. This method produces results that mirror findings based on structured interviews (Mo-rey, 1988; Westen & Muderrisoglu, 2003). For each personality disorder, we generated DSM-IV diagnoses both categorically (by applying DSM-IV de-cision rules) and dimensionally (by counting the number of criteria met).

RESULTSTable 1 presents demographics of the clinician-observers and patients. The patients (N = 1,201) averaged early middle age with substantial vari-ance; were approximately equally split by gender; were roughly 80% Cau-casian, with African American (n = 79) and Hispanic (n = 71) ethnicities reasonably represented; and reflected a roughly normal distribution with respect to social class. The mean of the GAF scores indicated substantial impairment overall, whereas their high variability indicated that the ob-servers followed our instructions for random selection of patients who met study criteria (not only patients with DSM-IV Axis II diagnoses). The most common Axis I diagnoses were mood, anxiety, substance use, and adjust-ment disorders. As assessed by applying DSM-IV criteria to the Axis II Checklist, avoidant and borderline personality disorders (PDs) were the

288 WESTEN ET AL.

most prevalent Axis II diagnoses, although all DSM-IV personality disor-ders were represented in relatively high numbers, with high rates of co-morbidity similar to those found in studies using structured interviews. A total of 929 patients (77.4%) met criteria for a DSM-IV personality disorder diagnosis. The prevalence of DSM-IV diagnoses was as follows: Paranoid, N = 277 (23.1%); Schizoid, N = 255 (21.2%); Schizotypal, N = 91 (7.6%); Antisocial, N = 219 (18.2%); Borderline, N = 350 (29.1%); Histrionic, N = 132 (11.0%); Narcissistic, N = 255 (21.2%); Avoidant, N = 491 (40.9%); Dependent, N = 227 (18.9%); and Obsessive-Compulsive, N = 209 (17.4%).

IDENTIFYING PERSONALITY FACTORS USING SWAP-II DATA: STATISTICAL CONSIDERATIONS

Ideally, factor analysis is performed on continuous, normally distribut-ed variables. Data in clinical psychology rarely if ever fit this description.

They tend to be sampled from the tails of the population distribution, re-sulting in skewed or otherwise nonnormally distributed variables (see Micceri, 1989). Furthermore, psychological rating scales tend to have rela-tively few response categories (Bernstein & Teng, 1989; Muthen & Kaplan, 1985). Factor analysis based on the commonly used maximum likelihood and generalized least squares methods can produce biased findings when applied to skewed and/or coarsely categorized data (West, Finch, & Cur-ran, 1995), yielding so-called “difficulty factors” that are psychometric ar-tifacts and substantively meaningless (McDonald, 1965; Waller, Tellegen, McDonald, & Lykken, 1996).

Many of these problems can be avoided by conducting factor analysis on tetrachoric or polychoric correlations rather than on Pearson correlations (Muthen & Speckart, 1983; Waller, 1999), or by utilizing “full-information” methods based on multidimensional item response theory (Mislevy, 1986; Wood et al., 2002). For these reasons, we factor analyzed the SWAP-II data using polychoric correlations and a least squares fit function using Micro-Fact 2.0 software designed for such applications (Waller, 2001).

Another methodological challenge concerns the treatment of sex differ-ences in the item correlation matrix (men and women may produce differ-ent item endorsement rates and/or different item correlations). When these differences go unrecognized, factor-analytic findings can be biased because correlations calculated on (sex) mixed samples reflect both with-in- and between-group sources of covariation (see Waller & Meehl, 1998, pp. 12–16). In the current sample, although men and women produced similar factor patterns, their item endorsement rates differed. For exam-ple, women scored higher than men on eating disorder items, whereas men scored higher than women on indicators of psychopathy. Had we ig-nored these differences, a factor analysis of the (uncorrected) data could produce spurious factors with items from conceptually distinct domains and spurious item cross-loadings that increase factor complexity (Sass & Schmitt, 2010).

Figure 1 presents a more thorough picture of how the men and women in our sample differed on their expected SWAP II item scores. Figure 1A shows the item endorsement rates and illustrates that, across sex, the distributions of item means are comparable. To examine these data at a higher level of resolution, we created a histogram of standardized item-difference scores (the mean differences were scaled by the standard devia-tions from the sample of women). Figure 1B elucidates numerous item-level differences. These figures convinced us of the need to partial out these sex differences before calculating a polychoric correlation matrix for the combined sample. Thus, to control group differences in item level, we computed polychoric correlation matrices separately for each sex, then averaged the matrices to form a combined matrix.

Before we discuss the factor-analytic findings, one final point concern-ing the polychoric correlations deserves mention. We collapsed several categories of the response scale to improve the precision of the estimated

290 WESTEN ET AL.

correlations. Although our sample is large relative to many psychopathol-ogy studies, the demands of our analytic procedures were extreme. When we cross-tabulated all item pairs, we noticed (using a computer program written for this task) that many cells in the 8-by-8 co-occurrence matrices had small joint frequencies. We expected this finding because many items had skewed distributions. Polychoric correlations may be poorly estimat-ed under these conditions, and the estimates can have large standard er-rors. Thus, to calculate more stable correlations, we recoded the original 8-point scales into 3-point scales.2

Following the procedures outlined above, we used MicroFACT 2.0 (Waller, 2001) to calculate a polychoric correlation matrix on the aggregate sample. Next, we extracted the eigenvalues from this matrix. Because their scree plot was not definitive, we extracted and inspected rotated factor solutions with 4 through 20 factors with numerous rotation algorithms.3

FIGURE 1. Distribution of item difficulties in male and female patients.

2. Scores of 0–3 were recoded as 0; 4–5 were recoded as 1; and 6–7 were recoded as 2. If the assumptions underlying the polychoric correlations are satisfied (latent bivariate normality), then recoding the item responses will not bias the correlations. Moreover, even when the underlying distribution departs from multivariate normality, the polychoric correlations will be estimated accurately under a wide range of latent distributions (Flora & Curran, 2004; Quiroga, 1992). However, failure to recode the data in moderate to small samples can result in highly biased correlations if the joint frequencies are small (Muthen & Speckart, 1983).

3. Each solution was rotated to optimize the Geomin, Oblimin (gamma = .00 or .25), and Promax (from an initial Varimax rotation raised to the third power) criteria using the gradient project algorithms of Robert Jennrich (Bernaads & Jennrich, 2005; Jennrich, 2002). Each

FACTOR-ANALYTIC RESULTS

Careful inspection of the analyses led us to choose a 16-factor solution rotated using Oblimin (γ = .25; solutions based on γ = 0 were virtually in-distinguishable from those based on γ = .25). Solutions with fewer factors combined diagnostically distinct symptoms, whereas solutions with more factors produced doublets (two item factors) that reflected little more than semantic redundancy among item pairs. Consideration of the fit criteria convinced us that the 16-factor solution was optimal for these data. For instance, the average communality in the 16-factor solution was .47, with less than 5% of the items having communalities of .30 or less. This solu-tion also reproduced the data matrix (i.e., the polychoric correlations) re-markably well; fully 80% of the reproduced correlations differed from their targets by .05 or less, and the overall root mean square residual (RMSR) = .05. These findings are well summarized by McDonald’s GFI = .93. In con-trast, the findings for lower-dimensional solutions were not impressive. For instance, in the 5-factor solution, the average communality was only .29, with over 55% of the items having communalities < .30. Consider-ation of the model residuals also suggested that a 5-factor solution was a severe underfactoring, because 15% of the reproduced correlations dif-fered from their targets by .10 or greater (RMSR = .07) and McDonald’s GFI was only .84.

On the basis of clear patterns of factor loadings, we labeled the 16 fac-tors as follows: (1) Psychopathy, (2) Psychological Health, (3) Obsessional-ity, (4) Schizotypy, (5) Emotional Avoidance, (6) Emotional Dysregulation, (7) Narcissism, (8) Anxious Somatization, (9) Sexual Conflict, (10) Depres-sion, (11) Social Anxiety/Avoidance, (12) Unstable Commitments, (13) Boundary Disturbance, (14) Histrionic Sexualization, (15) Hostility, and (16) Eating Disturbance.

We were unable to recover a higher-order structure resembling the FFM or the consensus four-factor model, which is derived from factor analyses of self-report and/or lay-report item sets. Because Factor 13 had limited internal consistency and Factor 16 can be interpreted as pri-marily an Axis I index (eating pathology), we recommend retaining the other 14 factors for future use, although we report data using all 16 scales here. Table 2 reports the factor loadings. Shaded items reflect items with high loadings that we retained in the final scales for each fac-tor; a small number of items with reasonably high loadings (often in the opposite direction from the vast majority of loadings on a given scale) were deleted from those scales because of low item-scale correlations, reduced coefficient α’s when included in the scales, and conceptual inco-

rotation was performed 500 times from random (orthogonal) spins of the unrotated solution to identify the most psychologically interpretable pattern. This last step was undertaken for two reasons: Factor rotation algorithms can “get stuck” in local maxima or minima, and fac-tor solutions at the global maxima or minima are not necessarily the most interpretable from among the various converged solutions (Browne, 2001; Rozeboom, 1992).

FACTOR STRUCTURE OF THE SWAP-II 309

herence with the scale (e.g., negatively scored suggestibility in a Hostility factor). Table 3 reports the factor correlations for the 16 obliquely rotated factors.

Two aspects of the data deserve comment. First, Table 3 illustrates a very clean simple structure solution. Second, as can be seen in Table 3, although the factors were allowed to correlate, with few exceptions most correlations were close to zero. This is a desirable quality for a multiscale inventory because it implies that each scale offers nonredundant informa-tion about the patient. Such information can be profitably summarized by factor scores because all 16 factors have high factor score validity coeffi-cients (Grice, 2001; McDonald & Mulaik, 1979), a situation uncommon among psychology scales (Guttman, 1955). Factor score validity coeffi-cients represent the correlations between the factor score estimates and the actual factor scores (see McDonald & Mulaik, 1979, for a relatively nontechnical discussion). Although the factors are clearly distinct, when we created factor-based scores from items with the highest loadings (de-scribed above), some of the seemingly anomalous findings (e.g., the ab-sence of any relationship between Depression and Anxious Somatization) disappeared. For example, Psychopathy correlated r = .43 with Narcissism and .54 with Unstable Commitments, and Depression correlated r = .23 with Anxious Somatization.

310 WESTEN ET AL.

DISCUSSIONThis study provides the first normative data on the factor structure of comprehensive personality descriptions obtained using the SWAP-II in a large, representative national clinical sample. The sample included pa-tients with personality dysfunction ranging from mild to severe, drawn from a wide range of settings including private practice, outpatient clinics, residential treatment settings, and forensic facilities. Factor analysis us-ing polychoric correlations with Oblimin rotation produced a simple struc-ture that resembled the structure identified in previous research using an earlier version of the SWAP instrument and different factor-analytic meth-ods (Pearson correlations with a Promax rotation; Shedler & Westen, 2004a). Several similar factors emerged in both samples, notably Psycho-logical Health, Psychopathy, Hostility, Narcissism, Emotional Dysregula-tion, Obsessionality, Histrionic Sexualization, and Sexual Conflict. With the exception of the latter scale, the same factors emerged from factor analysis of the SWAP-200-A for adolescents.

The major differences between the factor structures uncovered using data from the SWAP-200 and the SWAP-II were: (1) the SWAP-200 data yielded a Dysphoria factor, whereas the SWAP-II data yielded more differ-entiated Depression, Anxious Somatization, and Social Anxiety/Avoid-ance scales; (2) SWAP-200 factors related to schizoid, schizotypal, and avoidant pathology were reconfigured, producing SWAP-II Schizotypy, Emotional Avoidance, and Social Anxiety factors; (3) items that loaded on the SWAP-200 Dissociation factor tended to load on the SWAP-II Emo-tional Dysregulation factor; (4) an Unstable Commitments factor emerged with the SWAP-II; and (5) a Boundary Disturbance factor emerged with the SWAP-II.

Although continuity with the factor structure observed with the earlier edition of the SWAP is greater than discontinuity, with several scales re-markably similar in item content, as noted here, differences did emerge between the previous analysis and the current analysis, and attributing these differences to one source versus another can be difficult. For exam-ple, the current findings reflect substantial improvements in sampling, including greater than double the sample size; inclusion of patients re-gardless of whether they met criteria for a DSM-IV PD; and random selec-tion of patients (rather than clinicians choosing potentially prototype pa-tients with a given PD). These are very substantial sampling improvements that were central to the design of the current study.

In addition, the SWAP-II has the advantage of making use of the feed-back of hundreds of clinicians who used the SWAP-200 and alerted us about items that were ambiguous or difficult to score as well as personal-ity constructs that were not adequately covered in the previous item set. It additionally reflects psychometric refinements based on examination of poorly performing items (e.g., those with minimal variance, extremely low base rates, or highly overlapping content leading to correlations ≥ .70). This study also employed much more sophisticated factor-analytic proce-

FACTOR STRUCTURE OF THE SWAP-II 311

dures, such as the use of polychoric correlations and the partialing out of potential biases due to gender differences. These data-analytic improve-ments no doubt helped produce some “cleaner” factors, although factor analysis of the current sample using simple Pearson’s correlations with an Oblimin rotation, extracting 16 factors from the raw data (not adjusted by gender), produced factors highly similar to those reported here (though less well defined in terms of item univocality). Thus, the factors appear robust across factor-analytic methods.

The scales generally showed good internal consistency with a mean α of .73, although two (Boundary Disturbance and Sexual Conflict) were on the low side at .44 and .55, most likely because of the relatively small number of items (4 and 6, respectively) that loaded highly on these fac-tors. Space limitations preclude reporting validity data for the SWAP-II factors here; however, convergent validity and discriminant validity be-tween two independent observers for the original SWAP-200 traits are very strong, with correlations along the diagonal (convergent validity) averaging ≥ .70 and off the diagonal (discriminant validity) averaging approximately 0.0 (Westen & Muderrisoglu, 2006). Preliminary analysis of data from a new sample of more than 200 patients for which we have independent data from multiple sources (e.g., three independent interviewers as well as treating clinicians), to be reported elsewhere, suggests that these traits have similar properties in terms of convergent and discriminant validity between two independent sources, and that they predict multiple mea-sures of adaptive functioning assessed by independent informants.

TRAIT STRUCTURE

Several aspects of the trait structure of the SWAP-II are notable. The first is the identification of a Psychopathy factor that resembles, in many re-spects, the psychopathy construct as described by Cleckley (1941) and operationalized via the Psychopathy Checklist-Revised (PCL-R; Hare, 2003). Importantly, this factor emerged empirically, and did so in both the SWAP-200 and the SWAP-II, even though neither instrument was designed with this construct or measure in mind. Furthermore, the items charac-terizing the Psychopathy factor were clearly a subset of the SWAP-II items that emerged empirically as most descriptive of 91 incarcerated men who had scores > 30 (the clinical cutoff) on the PCL-R in an independent as-sessment (Blagov et al., 2011). The factor resembles the DSM-IV Antisocial PD construct, but it also incorporates additional constructs of theoretical and etiological relevance, including failure to learn from negative conse-quences, thrill and sensation seeking, and deficits in empathy. These find-ings lend support to the psychopathy construct and suggest that a single instrument may be able to assess not only psychopathy but also other fo-rensically relevant constructs, such as emotional dysregulation and other Axis II personality disorders. Compared to Cleckley’s psychopathy con-struct, the SWAP-II’s empirically derived Psychopathy factor features more

312 WESTEN ET AL.

proneness to violence and less narcissism, with the latter comprising an independent construct.

Second, as was the case with the SWAP-200, SWAP-II Obsessionality describes something quite different from high conscientiousness (or its opposite, which emphasizes impulsivity) as described by the FFM or the consensus four-factor model. Rather, it describes a construct closer to the classic clinical concept of an obsessional personality style (Blagov, Brad-ley, & Westen, 2007; Shapiro, 1965), which includes such characteristics as excessive concern with rules, self-righteousness, stinginess, preoccu-pations with dirt and cleanliness, rumination, and excessive devotion to work to the detriment of leisure and relationships.

More broadly, the factors that emerged tend to focus on a greater range of personality processes and dimensions than most trait measures. Some overlap with DSM syndromes (e.g., narcissistic personality disorder) but nevertheless capture trait narcissism; others capture what might be called endophenotypes, such as Schizotypy; and still others describe psychologi-cal processes, focusing on the kinds of internal states, transformations, and conditional “if… then” processes increasingly emphasized by general personality theorists across theoretical orientations (Mischel & Shoda, 1995; Westen, Muderrisoglu, Fowler, Shedler, & Koren, 1997; e.g., “Tends to become irrational when strong emotions are stirred up . . .” [emphasis added]). All of these would be consistent with the broad construct of “trait” as first described by Allport (1937). These trait constructs may prove use-ful as modifiers of syndromal diagnoses, whether the traditional personal-ity disorder diagnoses of DSM or empirically derived diagnostic prototypes as we have proposed elsewhere (e.g., Schizoid Personality Disorder with high or low Schizotypy) (Westen et al., 2012).

A third aspect of the factor structure concerns the clear distinction be-tween emotional dysregulation and factors reflecting negative affectivity. This distinction between emotional dysregulation and negative affectivity has been replicated across multiple studies using both editions of the SWAP, with both adults and adolescents; the Affect Regulation and Expe-rience Q-sort (Westen et al., 1997); and a range of other measures (Brad-ley, DeFife, et al., 2011; Miller & Pilkonis, 2006). Emotional Dysregulation as identified here is conceptually very similar to an identically named su-praordinate factor uncovered empirically in both clinical and general sam-ples by Livesley et al. (1998) using the Dimensional Assessment of Person-ality Disorder–Basic Questionnaire (DAPD-BQ). The SWAP-II factor captures a number of facets that overlap with subscales of the DAPD-BQ, including emotional instability, intense negative emotions, cognitive dys-regulation (irrationality and dissociation) under stress, and identity diffu-sion. These findings, as well as recent findings linking emotional dysregu-lation to distinct genes not associated with negative affectivity (Bradley, Westen, et al., 2011), suggest that emotional dysregulation—the tendency to experience extreme feeling states and to resort to highly maladaptive strategies to try to regulate them—is distinct from the stably negative af-

FACTOR STRUCTURE OF THE SWAP-II 313

fect seen in such disorders as dysthymia and generalized anxiety disorder. Although emotional dysregulation and negative affectivity coexist in many patients (particularly those with borderline personality disorder), they ap-pear to have distinct etiologies and treatment implications.

Fourth, the emergence of an Emotional Avoidance trait was an unex-pected but conceptually and clinically meaningful finding with obvious links to such personality constructs as obsessional style (Shapiro, 1965), illusory mental health (Shedler et al., 1993), repressive coping (Weinberg-er, 1995), avoidant, dismissing, or deactivating attachment patterns (Doz-ier & Kobak, 1992), and emotional avoidance (Hayes & Melancon, 1989).

Fifth, the Schizotypy factor is consistent with prior research on the schizotypal personality disorder and the schizophrenia prodrome (e.g., Hawkins et al., 2004), capturing both positive (e.g., odd and idiosyncratic reasoning and perception) and negative (e.g., concreteness of thinking, subthreshold disorganization in thinking) symptoms. It is conceptually re-lated to the Eccentric Perceptions scale of the Schedule of Nonadaptive and Adaptive Personality (SNAP), and its content is conceptually similar to the DSM-IV diagnosis of Schizotypal PD.

Finally, it is noteworthy that the SWAP-II does not produce a higher-order structure resembling the FFM (e.g., Digman, 1990), the consensus four-factor model (Markon et al., 2005), or the five factor personality pa-thology trait model recently proposed for DSM-5. Perhaps the greater com-plexity of some of the SWAP items, designed to capitalize on expertise gained through professional training and experience, permits assessment of clinically important aspects of personality that have not been adequate-ly captured by item sets that rely primarily on personality constructs sa-lient to untrained laypersons. For example, the following SWAP-II items address personality phenomena that are readily recognizable to clinicians but would be extremely difficult to capture via self-report and do not re-semble the level of discourse commonly used by lay observers:

“Is invested in seeing and portraying self as emotionally strong, untrou-bled, and emotionally in control, despite clear evidence of underlying inse-curity, anxiety, or distress.”

“When upset, has trouble perceiving both positive and negative qualities in the same person at the same time; sees others in black or white terms (e.g., may swing from seeing someone as caring to seeing him/her as ma-levolent and intentionally hurtful).”

“Appears unable to describe important others in a way that conveys a sense of who they are as people; descriptions of others come across as two-dimensional and lacking in richness.”

LIMITATIONS

This study concerns the factor structure and content validity of the SWAP-II and does not address questions of interrater and test–retest reliability of the instrument or its construct validity. We present such evidence else-

314 WESTEN ET AL.

where (see also Westen & Shedler, 2007). Future research should evaluate the replicability of the factors presented here using confirmatory factor analysis. Furthermore, we cannot be certain that this sample is represen-tative of the population of patients treated for personality pathology in some absolute sense, although it is more representative than virtually any other sampling approach of which we are aware (in comparison, e.g., to sampling patients who meet PD criteria based on structured interviews from a single setting or small number of clinics affiliated with a university hospital).

CONCLUSIONS AND IMPLICATIONSThe findings suggest that the factor structure of an instrument designed to quantify the concepts and observations of experienced clinicians does not reproduce the FFM or any of its variants. This finding makes sense in light of the lexical hypothesis underlying the FFM, which suggests that language evolves to fit its purposes. The purposes of lay observation and clinical observation of personality are markedly different (as is the level of expertise of the observer). Just as oncologists tend to use more refined concepts than “bumps” or “growing red dots” to describe different forms of cancer, the language required by clinical observers who regularly observe and treat the more pathological end of the personality spectrum should be more differentiated than the language of lay observers (particularly when the latter is constrained for methodological reasons not to exceed a sixth-grade reading level). Factor analysis of the SWAP-II produced a coherent solution with simple structure whose factors were generally highly reli-able, clinically and empirically recognizable, and could not be reduced to a hierarchical structure with a small number of superordinate factors.

More broadly, the finding of clinically coherent factors is consistent with an increasing body of evidence, congruent with research in other medical disciplines (e.g., Arocha, Wang, & Patel, 2005), that clinically trained ob-servers can make reliable, quantifiable diagnostic inferences when these inferences are made at a level of abstraction close to that used in everyday practice (at which doctoral-level clinicians have expertise; DeFife et al., 2010; Westen & Weinberger, 2004). We have yet to observe substantial dif-ferences in the way clinically trained observers of different theoretical ori-entations use the SWAP. This suggests that, when asked to describe a particular patient (as opposed to their hypotheses or beliefs about psycho-pathology), experts in psychopathology are able to do what most people are able to do, namely to describe a person with an appropriate level of fidelity using language appropriate to their level of expertise.

With the next revision of the DSM on the horizon, that revision should be made in the light of data comparing the validity and reliability of alter-native methods of assessing and classifying personality pathology, partic-ularly dimensional diagnosis. Virtually no data exist that compare dimen-sional traits versus diagnostic prototypes (descriptions of constellations of functionally related personality characteristics that comprise clinical syn-

FACTOR STRUCTURE OF THE SWAP-II 315

dromes) on indices of validity (Westen, Gabbard, & Blagov, 2006). Like-wise, no data of which we are aware compare traits derived from self-re-port measures with those derived using item sets designed for clinically expert informants. We are currently testing the comparative validity of multiple alternative approaches to dimensional diagnosis of personality in a study using a multitrait-multimethod approach with a sample size large enough to discriminate the relative validity of these alternative approach-es. If future editions of the DSM are to reflect the best available science, then appropriate scientific comparison of alternative diagnostic systems is a prerequisite.
