Habit as both a direct cause of intention to use a condom and as a moderator of the attitude-intention and subjective norm-intention relations

Abstract

Undergraduates at an American university were asked questions about their attitudes, subjective norms, habits, and intentions towards using a condom during sexual intercourse. Consistent with previous research (Chan and Fishbein, 1993; Trafimow, 1994), intentions were well predicted by attitudes and subjective norms (r = 0.88 and r = 0.73, p < 0.01 in both cases). Intentions were also well predicted by habits (r = 0.77, p < 0.01). More interestingly, however, for participants who were in the habit of using condoms, attitudes and subjective norms were not significant predictors of intentions to use condoms in the future (r = 0.18 and r = 0.10, p<0.1 in both cases). In contrast, attitudes and subjective norms were strong predictors for participants who were not in the habit of using condoms (r = 0.81 and r = 0.61, p < 0.01 in both cases). These findings were replicated in a second study.
