ABSTRACT
Although a plethora of research has been conducted on the profiles of substance abusers
and the efficacy of various drug treatment programs in lowering post-treatment recidivism, there
has been a dearth of studies on the treatment progress itself, the “black-box” in drug/DWI
treatment research. This study examines the indicators of treatment noncompliance among a
sample of DWI Court Program participants of one county in a Southern state. Results of
regression indicate that clients with delinquent peers were less likely to comply with treatment
conditions. Results indicate that the odds of a client with criminal acquaintances to be non-
compliant were 4.8 times greater than for a client with no criminal acquaintances (p<.05). A
greater count of sanctions and incentives received also increased the odds of being non-
compliant. The odds of a client being noncompliant were 1.5 times greater when the count of
incentives increased by one unit. Similarly, the odds of a client being noncompliant were 2.2
times greater when the count of sanctions increased by one unit. Results indicate that the quality
of incentives and sanctions rather than the number or rate granted to clients may be more
predictive of treatment compliance.

Unlocking the Black Box: Indicators of Treatment Noncompliance
in a Sample of Repeat DWI Offenders
INTRODUCTION
Current research on drinking-while-intoxicated (DWI) and drug courts focus primarily on
post-treatment recidivism (Bouffard, Richardson, & Franklin, 2010; Fielding, Tye, Ogawa,
Imam, & Long, 2002; Whitlock & Lubin, 1998). The over-emphasis on outcome evaluation
research for substance abuse treatment has led some scholars to stress the need for more
treatment process studies (McLellan, Woody, Metzger, McKay, Durell, Alterman, & O’Brien,
1997).
Treatment Engagement and Noncompliance
Treatment process studies focus on factors affecting retention (Dakof, Tejeda, & Liddle,
2001; Rempel & DeStefano, 2001). Recent research findings suggest, however, that treatment
engagement is necessary for successful program completion (Joe, Broome, Rowan-Szal, &
Simpson, 2002; Marrero, Robles, Colon, Reyes, Matos, Sahai, Calderon, & Shepard, 2005; Sung,
Belenko, & Feng, 2001; Sung, Belenko, Feng, & Tabachnick, 2004). Treatment engagement is a
broader term than treatment retention, encompassing several aspects of the treatment process,
including attendance, compliance with program conditions, and active participation in mandatory
meetings (Sung et al., 2001).
The Texas Christian University (TCU) Treatment Process Model
Simpson’s (2004) treatment process model describes a sequential phase for treatment,
including factors that directly impact compliance (Simpson & Knight, 2004). According to the
TCU treatment model, an effective treatment process requires the interplay of various

components, starting with early engagement. Early engagement is influenced by social and
psychological motivation at intake (De Leon, 2000; Lang & Belenko, 2000) and social support
networks (Slaght, 1999), including family and friends (De Civita, Dobkin, & Robertson, 2000;
Miller, 2003; Shapiro, 1998).
Studies on early engagement examine factors affecting program compliance (McKellar,
Kelly, Harris, Moos, 2006; Sung et al., 2004). Peck, Arstein-Kerslake, and Helander (1994)
found that among a sample of driving under the influence offenders randomly assigned to
treatment programs between 1988 and 1981, noncompliant offenders tended to be younger, less
educated, with lower levels of income. Sung et al. (2004) found that educational attainment
increased the likelihood of treatment compliance. Sung et al. (2004), however, did not find any
significant effect of past employment on treatment engagement, contrary to prior research
(Anglin & Hser, 1990; Peters, Haas, & Murrin, 1999).
Other studies also examine the influence of various incentives such as vouchers (Griffith,
Rowan-Szal, Roark, & Simpson, 2000; Higgins, Alessi, & Dantona, 2002; Prendergast, Hall,
Roll, & Warda, 2008), small gifts, bus tokens, or car fare (Rowan-Szal, Joe, Chatham, &
Simpson, 1994), and drawing prizes contingent on negative urinalysis. Voucher-based
incentives have been found effective in increasing session attendance and drug abstinence in
various types of drug treatment settings (Petry, Martin, Cooney, & Kranzler, 2000). Other types
of behavioral interventions such as social recognition and reward for good behavior were also
effective for community based programs (Rowan-Szal, et al., 1994).

RESEARCH QUESTION
This study analyzes factors that influence treatment noncompliance in a court program
for repeat DWI offenders based on the TCU Treatment Model. This is of interest to practitioners,
especially court program administrators and judges, because of the difficulty and uncertainty of
program success in various criminal justice programs. Also, since the DWI court program is a
pilot program implemented relatively recently in this particular county, program designers and
implementers would benefit from analysis of factors that influence success in the program.
Results of the study will hopefully lead to a more informed selection of qualified individuals
who are most likely to comply, as well as better monitoring of individuals who are at greater risk
of noncompliance.
The current study tests the following hypotheses:
Supportive Social Network
Social support systems affect the black box of treatment process, including early
engagement. Program clients with supportive spouses or partners were more likely to comply
with program conditions (Wright, Cullen, & Miller, 2001). This study hypothesizes that the
lesser the quality of client relationship with spouse or significant other, the greater the treatment
noncompliance.
Delinquent Peers
The quality of one’s peers and associations also influence early engagement or
noncompliance. According to Sung et al. (2004, p. 15), not all close friendships positively affect
treatment compliance and only those friends “who are not themselves engaged in illegal or
addictive behavior can provide support.” The study hypothesizes that clients who have

delinquent peers are less likely to comply with program conditions and more likely to engage in
treatment noncompliance.
Conventional Social Involvement
Compliant clients often come from more socially stable groups, whereas poorly educated
or unemployed/low-income clients are more likely to engage in treatment noncompliance (Sung
et al., 2001). The study hypothesizes that clients who have less conventional social involvement
are more likely to engage in treatment noncompliance.
Treatment Motivation
Patient attributes at intake, such as motivation for change or readiness for treatment, and
problem severity at intake affect early engagement (Simpson, 2004). Behavioral interventions
such as use of sanctions and incentives have also been found to affect early engagement
(Simpson, 2004). Thus, the study hypothesizes that clients who have less treatment motivation
(measured by alcohol and drug problem at intake, use of incentives and sanctions) are more
likely to engage in treatment noncompliance.
METHODS
Sample and Data
The sample consists of 87 repeat DWI offenders who participated in a 24 months
criminal justice-mandated DWI court program in a large southern urban county. At the time of
this study, 164 individuals were enrolled in the program, at various stages. For purposes of this
study, only those participants who had fully completed the Level of Supervision Inventory –
Revised (LSI-R) intake assessment were considered (N=87). The LSI-R was not implemented
immediately by program administrators upon the creation of the program. This intake instrument

was implemented more consistently during treatment of later cohorts. All program participants
upon whom the LSI-R was administered are included in this study.
The DWI Court Program under study was implemented in December 2007 pursuant to a
legislative mandate requiring the inclusion of second offense DWI offenders in either a county’s
already established drug court or a specifically developed treatment court. The program requires
clients to undergo assessment, attend court sessions regularly, perform community service, make
fee payments, serve jail time, wear the Secure Remote Alcohol Monitoring (SCRAM) device,
meet regularly with their community service officer and undergo periodic alcohol and drug
testing. Clients must also participate in alcohol treatment programs, 12-step programs, complete
a repeat offender class and attend victim impact panels.
Dependent Variable
Official court data contained several indicators of treatment noncompliance. An index of
noncompliance was computed from thirteen infractions types that were recorded by the courts.
This index of noncompliance included absence from court sessions, SCRAM violations,
unexcused absence from Alcoholics Anonymous meetings, unexcused absence from supervision
appointment, unexcused absence from treatment, breathalyzer violations, ignition interlock
violations, driving without a license, missed urinalysis, positive urinalysis, tampered or diluted
urinalysis, absconding, and new arrest.
Since the objective of the current study was to determine the factors predicting
noncompliance among DWI offenders, the count dependent variable was recoded into a
dichotomous variable (“0” = compliant group, and “1” = noncompliant group). The
noncompliant group had committed at least one infraction during their time in the program.

Independent Variables
The independent and control variables were measured as follows:
Supportive social network. The family/marital scale of the LSI-R provides constructs
that can be used to measure the supportive social networks. This study used the scale measuring
satisfaction with intimate partner (q.23).
Conventional social involvement. The study examined two variables: current
employment status (full-time or part-time) and educational attainment (less than high school
degree, high school degree or GED, and college degree).
Delinquent peers. The delinquent peers’ hypothesis was measured using a dichotomous
variable from the LSI-R companions’ scale. This question (LSI-R q.33) asked the respondent
whether they had had criminal acquaintances during the 12 months preceding the assessment.
Treatment motivation. Treatment motivation was examined using three measures:
client level of satisfaction with current alcohol problem (LSI-R, q.39), recoded into a
dichotomous variable (yes/no); incentives; and, sanctions. An index of incentives1 and of
sanctions2 was computed for each client.
Control variables. Control variables include gender, age, ethnicity, and length of
program enrollment.
1 Incentives include number of commendations by court officer; lower level of supervision; Judge’s praise; report
closer to home; adjustments to or removal of curfew; gift card; return of driver’s license; field visit instead of office
visit; mail in reporting, sobriety chips; and removal of SCRAM device. 2 Sanctions include verbal warning, increase in CSR, community service, cognitive exercise, thinking report, higher
level of supervision, inpatient treatment, weekend in jail, and removal from court.

RESULTS
Descriptive Statistics
The sample of 87 participants who had completed an LSI-R intake assessment was
predominantly male (82.8%), White (50.6%), employed full-time or part-time (83.9%), and at
least 81.6% had a high school degree or GED. The average age was 36 years-old. Clients were
enrolled in the program for an average of 513 days. Approximately 75% of all clients were
noncompliant.
Bivariate correlations
Bivariate correlations between predictor variables are presented in Table 1 below. Chi-
square tests of group distribution were used to assess the association between categorical
predictor variables and the dependent variable. The relationship between continuous predictors
and the treatment compliance was measured using t-test of group means. Bivariate analysis
results indicate that only two of the predictors, incentive and sanction counts, were significantly
correlated with our dependent variable.

Multivariate Analyses
Logistic regression was conducted to test our various hypotheses and determine
predictors of treatment noncompliance in a DWI court program setting. Prior to running the
logistic regression models, a Pearson’s product moment correlational analysis was conducted for

checked for multivariate outliers and multicollinearity. The data did not contain any multivariate
outliers at p = .001 (χ2 = 32.909; d.f. = 12). Also, no Variance Inflation Factor (VIF) value
exceeded 1.7 for any variable (multicollinearity is a problem only if VIF values are greater than
10).

Regression results indicate an overall model of three predictors (criminal acquaintances,
incentives count, and sanctions count) was statistically reliable in distinguishing between
compliant and noncompliant DWI clients (-2 Log Likelihood=72.724; χ2(2)=25.668, p<.01),
after controlling for length of enrollment. The model correctly classified 80.5% of the cases, and
accounts for 26.1% of the variance in the dependent variable (noncompliance). Regression

Clients with delinquent peers were more likely to be noncompliant. The odds of a client
with criminal acquaintances to be noncompliant were 4.8 times greater than for a client with no
criminal acquaintances (p<.05). A greater count of sanctions and incentives also increased the
odds of noncompliance. The odds of a client being noncompliant were 1.5 times greater when
the count of incentives increased by one unit. Similarly, the odds of a client being noncompliant
were 2.2 times greater when the count of sanctions increased by one unit.
Consistent with prior literature, delinquent peers was found to be a significant predictor
of treatment noncompliance (Sung et al., 2004). The results failed to support findings in
previous literature that employment status and level of education completed have significant
effects on program noncompliance. Incentives increased treatment noncompliance, contrary to
findings in previous studies that incentives improve program participation .
DISCUSSION
Results indicate that delinquent peers, incentives, and sanctions significantly predict
treatment noncompliance. Associating with delinquent peers increases the odds of
noncompliance by 4.8 times (p<.05). A practical significance of this study indicates that clients
must be encouraged to cultivate pro-social peers through involvement in various socio-civic
groups and organizations with pro-social goals. Community involvement in neighborhood
associations and socio-civic organizations may be an aspect of the treatment process mandated
by the DWI court. The comparative small size of this sample, however, renders the results
tentative. Results of this study may not be generalized to other DWI court programs.
The study showed that increasing the number of incentives increased noncompliance.
This study, however, did not examine the timing of incentives (i.e., the phase during which it

was given). Examination of the types of incentives may explain the positive association with
noncompliance. Examples of incentives are lower levels of supervision, adjustments to or
removal of curfew, and removal of SCRAM device. Granting these incentives at the early stages
of the program where the client may not have undergone behavioral changes conducive to
treatment compliance possibly does not lead to greater compliance. Lesser supervision, for
example, may lead to more infractions by the client if granted too early in the treatment program.
At least one study also indicates that vouchers may not be useful in improving treatment
compliance (Prendergast, et al., 2008). Prendergast et al. (2008) found that program participants
who received twice-weekly vouchers for good behavior were more likely to have poorer
performance. They concluded that the judge’s influence within the courtroom had a “stronger
impact” on engagement rather than the “relatively low-value vouchers” granted as incentives
(Prendergast et al., 2008, p. 125). Program administrators of the current DWI program might
consider revising the incentive grid presently enforced to encourage participation and
compliance with treatment conditions. The quality of incentives may be more useful in
determining treatment compliance than the number or rate of incentives granted to clients.
