WHY DO HOMOSEXUAL MEN RELAPSE INTO UNSAFE SEX - PREDICTORS OF RESUMPTION OF UNPROTECTED ANOGENITAL INTERCOURSE WITH CASUAL PARTNERS

Objective: To assess predictors of relapse into unprotected anogenital intercourse with casual partners among homosexual men in Amsterdam, T he Netherlands. Design: A prospective study ongoing since October 1984 . Methods: Self-reported data on sexual behaviour were obtained at 12 semi-annual intervals. Participants who reported unprotected anogenita l intercourse with casual partners at wave 12 but not at wave 11 were considered to have relapsed into unsafe sex (n = 47). Men who did not report unprotected anogenital intercourse at wave 11 or at wave 12 wer e considered to have maintained behaviour change (n = 197). Results: R elapse into unsafe sex with casual partners occurred more frequently a mong men with a less positive attitude towards condom use, lower perso nal efficacy with respect to using condoms with casual partners, a wea ker intention to avoid anogenital intercourse with casual partners and those who were not involved in a primary relationship. Intention to a void anogenital intercourse with casual partners was related to an ind ividual's attitude, normative beliefs and personal efficacy with respe ct to avoiding anogenital intercourse. Conclusions: In order to improv e motivation it is important to support homosexual men in their person al decision-making process, which may be more resolute when the outcom e is in accordance with individual preferences. Therefore, health educ ation should be community-based and sensitive to individual needs.
