'This ar t icle ap plies recent developments in cognit ive-social theory to heal th-protective behavior ,
ar t iculat ing a Cognitive-Social Health In forma tion Processing (C-SH IP) model . T his m odel of the
genesis and maintenanc e o f health-protect ive behavior focuses on the ind ividual ' s encodings and
construals, expectancies, affects, goals and values, self-regulatory competencies, an d the ir interac-
t ions with each o ther and the heal th-relevant information in the course of cognitive-affect ive p ro-
cessing. In processing heal th inform ation, individuals are assume d to differ in bo th the accessibil i ty
of hese mental representat ions and the organizat ion of relat ionshipsamong them . In this ar t ic le , the
mo del is app lied to analyze and inte grate the often-confusing findings on breast self-examination in
cancer screening. Implicat ion s are considered for assessments and interventions to enhance adher-
ence to complex, long-term, health-protective regimens, tailore d to the needs an d characteristics o f
the individual.

BSE has been prom oted for over 40 years as a low-cost cancer
screening techn ique (Eggertsen & B ergman, 1983). I t involves a
mo nthly procedure in which a w om an visual ly inspects an d m an-
ually palpates her breas t s and und erarm area in a sys tematic fash-
ion to detect lum ps, thickening, changes in contour, swell ing, dim -
pl ing o f the skin, and discharge f rom or changes in the nipple
(Am erican C anc er Society, 1987). Findings o f several studies,
both retrospective and prospective, show that breast cancer pa-
t ients who rep or ted BSE pract ice before the discovery of thei r di s-
ease present wi th smal ler tum ors an d are less likely to have axi l lary
l y m p h n o d e i n v o l v e m e n t t h a n a r e w o m e n w h o d o n o t p e r f o r m
BSE (e.g., Foster & Cos tanza, 1984; Foster et al . , 1978; Gre enw ald
et al. , 197 8; Lo ck ere t al . , 1989; Semiglazov & Moiseenko, 1987).
Nonetheless, ma ny questions rem ain ab out the sensit ivi ty of BSE
relative to other screening behaviors (especially mammography)
and a bo ut the degree to which the practice of BSE contributes to
survival rates from the disease in women who are also obtaining
m am m og ram s (Baines , 1989; Grady, 1992; O 'Ma l ley & Fletcbet ;
1987; Senie , Lesser ; Kinne, & Rosen, 1994) . H ov ~v ~ the
effectivenessof BSE depends o n whether i t is practiced regularly and
comp etent ly (GIV IO, 1991; Hugu ley & Brown, 1981; New com b et
a l ., 1991). For example, only 25-35 of wom en perform BSE at
the recommended f requency (Celentano & Hol tzman, 1983;
Cham pion, 1988; Mu rray & McMil lan, 1993) , and even fewer do
so profic iently (Celentano & H ol tzman, 1983; GIV IO, 1991; Howe,
1981; Jacob , Penn, & B rown, 1989 ; Roberts, French, & D uffy,
1984; Sheley & Lessan, 1986). I t is therefore im po rtan t to specify
the condit ions th at facil itate the regular p erform anc e of proficient
BSE and to ident ify the wom en m ost l ikely to pract ice BSE com pe-
tently and to profi[ from it .

Choice ofMediating Units
With regard to the ch oice of mediat ing unit s , the C -SH IP incor-
porates the cumulative f indings and concepts emerging f rom cog-
nit ive and social theories o f social info rma tion pro fessin g ov er
ma ny years (e .~ , Bandura, 1986 ; Can tor & Kihls t rom, 1987;
Carver & Scheier , 1981; Dodge, 1986 ; Mischel , 197 3, 1990) .
These basic units, called cognit ive-affective units (Mischel &
Shoda, 1995), include the me ntal representations of the person 's
encoding cons tructs and strategies, beliefs, expectancies; affects,
goals, and values. The se units hav e had a long history in psychol-
ogy and play a role as variables or const ructs in on e or mo re exis t-
ing theories in the health do ma in (Glanz, Lewis, & Rimer, 1990).
Cogni tive-social theory i s not u nique in the m ediat ing uni t s i t
ident i f ies : These const ructs are common products that have
emerged over m an y years in psychology, reflecting the sha red he ri-
tage of the field as a cum ulative science. Thus , ho w people proce ss
inform ation ab ou t their health risks, prospects, an d self-protective
options greatly depends on their strategies for encoding or inter-
pret ing heal th informat ion a bou t thei r i llness s ta tes and sym ptom s
(G ritz & Bastani , 19 93; E. Leventhal, Suls, & Leventhal , 1993; H.
Leventhal , 19 70; H. Leventhal , Diefenbach, & Leventhal, 1992).
Likewise, mo st mod els of health-protective behaviors include the
expe ctancy and value cons tructs (Fischoff, Goitein, & Shapira,
1982; Rotter, 1954). T he he alth belief mo del (Becket; 1974; Jan z
& Becker, 1984; Ki rscht , 1988; H. Leventhal, Ho chb aum , & Ro -
senstock, 1960) and protect ion mot ivat ion theory (Maddux &
Rogers, 1983; Prent ice-Dun n & Rogers , 1986) em phasize the per -
son 's a t tent ion to the co st and heal th consequences for not per -
forming rec om men ded behaviors , as do subjective expected ut i li ty
theo ry (Edwards, 1954; Ronis, 1992; Sutton, 1982), the theory of
reasoned action (Ajze n & Fishbein, 198 0; Fishbein & Ajzen,
1975 ) , and the the ory of planned behavior (Ajzen, 1985; Ajzen &
Madden, 1986), al though each uses som ewh at different term s.
As t he above- c i ted mod e l s have r ecogn i zed , hea l t h - p r o tec t i ve

Ta b l e
Types of Cognitive-Affective Me diating Units in Health Information Processing
and E xecu tion o f Health-Protective Behavior
Health-relevant encodings
Strategies and constructs for encoding o f self and situations w ith regard to health and wellness, health
risks an d vulnerab ilities, and illness an d disease. Includes attentional strategies for selecting and
processing potential health-threats and dangers (e.g. , mo nitoring -bluntin g by scanning fo r and
amplifying, or avoiding an d attenuating, information abou t possible health dangers and stressors).
Health beliefs and expectancies
Specific beliefs and exp ectations activated in health inform ation processing. Includes expec tancies abou t
both outcom es (e.g. , subjective l ikelihood of one 's developing breast cancer based o n o ne's genetic
pedigree and lung cancer from smoking) and self-efficacy xpectancies (e.g., for adhering to regular BSE
in cancer screening and fo r giving up tobacco).
Affects emotions)
Affective states activated in health information processing (e.g., anxiety, depression, hop efulness, negative
feelings abo ut the self, irritability, an d anger).
Health goals and values
Desired and valued health ou tcom es and states and their subjective importance (e.g., i t is cri tical to have
healthy breas ts) and go als for health-relevant life projects (e.g., dieting an d exe rcising regularly).
Self-regulatory competencies and s kills or generating and maintaining health-protective behavior
Know ledge and strategies for dealing with specific barriers to health-protective behaviors and for
construction and mainten ance of health-protective behaviors (e.g., skills required fo r proficient breast
self-examination in cancer screening). Includes self-regulatory strategies and behavioral scripts (e.g., self-
rewards and anxiety managem ent) for executing, maintaining, an d adhering to long-term, health-
protective be havior plans a nd life projects (e.g., strategies for goal-directed delay o f gratification).

3 Similar to the BSE li terature, the research o n fear-arousing comm u-
nications in general is mixed, such that some studies find a 0-shaped
relationship between fear and adoption of, o r adherence to, health-pro-
tective behaviors, wherea s other stud ies find a positive, linear relation-
ship (see Sutton, 1982, for a review).
4 One study reported no relationship between self-efficacybeliefs and
subsequent performance (Calnan & Moss, 1984). How ev~ BSE practice
was defined in terms not only of how frequently the behavior vos per-
formed bu t also of how com petently it was performed. This combined
assessment may have dam pened the effecto f self-efficacyon BSE because
women otten overestimate he quality of heir exams (Celentano & Holtz-
man, 1983;Jacob et al. , 1989).

cussed next (Mi ller, 1989, 1995, in press) .
To illustrate, high m onitors low blun ters ) generally see health
threats pervas ively and scan for them , a t tending intent ly to bodi ly
cues, symp toms, and r i sk informat ion (Mi l ler , Comb s, & Kruu s ,
1993; Miller, Roussi , Altma n, H elm , & Steinberg, 1994 ; Miller,
Roussi , Caputo, & Kruus, 1995; Schwartz, Lerman, Miller, Daly,
& M asny, 1995) . The y tend to see themselves as fragile and vul -
nerab le and are sensit ive to cues ab ou t possible disease and i l lness,
part icularly when dealing with potential ly chronic, un con trollable
stressors (Miller, Brody, & Su mm erto n, 1988; Miller, Lein bach , &
Brody, 1989 ; Miller et al ., 1994; M uris & v an Zuu ren , 1992; Step-
toe & Vogele, 1992; van Zuure n & W olfs , 1991 ) . This co gni t ive-
at tentional focus on threat an d dan ger act ivates anxiety and pro-
longed arousal s ta tes (Ga rd, Edwards , H arr i s , & McC orm ack,
1988; Ler ma n et a l. , 1990; Mi l ler & M angan, 1983; Phipps &
Zinn, 1986; van Zuu ren, 1993; E Wardle e t a l. , 1993; J . Wardle ,
1995; J. Wardle, Pernet , Coll ins, & Bourn e, 1994).
In the face of persistent , highly severe threats, wh ich high m on -
i tors encode as par t icularly catas t rophic (L erm an et a l ., 1995; Mi l-
ler e t a l. , 19 94, 1995, in press ; Mu ds, de Jong, van Zuu ren, & ter
Horst , 1994 ; Schwartz et al ., 1 995 ; Spa rks & Spirek, 198 8; van
Zuu ren & Muris , 1993) , intrus ive ideation and acco mp anying
anxiety may become unbearable and t r igger avoidance ef for t s .
High m oni tors therefore may ul t imately tend to reso r t to ext reme
defensive strategies, such as denial and disengagement, in an in-
creas ingly d~perate ef for t to suppress and dis tance themselves
f rom awareness of thei r own int rus ive ideat ion. Low m oni tors (or
high blunters) , however, in the ext rem es tend to encode personal
r i sks by denying thei r existence and to av oid threatening cues f rom
the outset , refusing to at tend to an d assimilate info rm ation tha t is

(Miller et al ., 1993, 199 4; M ill ~ Rodoletz, Schroeder, Ma ngan , &
Sedlacek, in press) . Consequent ly, anxiety i s not arous ed and, wi th
thei r sense of nvulnerabi li ty , they m ay not f orm even the intent ion
to pract ice BSE (see a l so Salovey & Birnba um , 1989; Weinste in,
1983, 1 984, 1989) . Effective coping wi th threat should be greater
wh en individuals develop discriminativeness and flexibil ity in their
a t tent ional s t ra tegies , so they c an ass imi la te new informa t ion ( e .g.,
a l lowing them to accep t the need fo r BSE) , w i thout becom ing ob-
