Attitudes-norms research (the theories of planned behavior and reasoned act
ion) has been successful in accounting for many types of behavior change. O
ne of the strengths of this approach has been to combine individual beliefs
and normative influences in the explanation of behavior change. However, t
he conceptualization of normative influence in these theories makes very st
rong assumptions about self-awareness in the selection of normative referen
ts. These assumptions are particularly problematic when applied to female c
ocaine smokers, who report frequent sex while under duress or while cogniti
vely impaired. In this study the original conceptualization of normative in
fluence and two alternatives (assuming emotion-based and interaction-based
selection of normative referents) are operationalized to evaluate stage of
change for condom use among women who are heavy crack cocaine users with mu
ltiple sex partners. Results show that stage of change for use of condoms w
ith nonmain partners is best accounted for by interaction-based selection o
f normative referents.
