Abstract

Little is known about the amount of Motivational Interviewing (MI) needed to reduce risky sexual behavior among People Living with HIV/AIDS (PLWHA) or the roles self-efficacy and motivation to practice safer sex play. Among 183 PLWHA who received safer sex MI and were surveyed every 4 months over a 12 month period, we used hierarchical negative binomial regression models to examine the association between amount of counseling time and sexual risk behavior. We performed mediation analysis to evaluate whether changes in self-efficacy and motivation explained this association. This study found that as MI time and number of provided sessions increased, participants' sexual risk behavior decreased. The effect of MI time and number of sessions on sexual behavior was mediated by self-efficacy but not by motivation to practice safer sex.

摘要

人们对 Motivational Interviewing(MI)在减少 HIV/AIDS 感染者(PLWHA)中的危险性行为方面的作用以及自我效能感和实施安全性行为的动机所起的作用知之甚少。在 183 名接受安全性行为 MI 并在 12 个月的时间内每 4 个月接受调查的 PLWHA 中,我们使用分层负二项式回归模型来检验咨询时间与性风险行为之间的关联。我们进行了中介分析,以评估自我效能感和动机的变化是否解释了这种关联。本研究发现,随着 MI 时间和提供的咨询次数的增加,参与者的性风险行为减少。MI 时间和咨询次数对性行为的影响是通过自我效能感来介导的,而不是通过实施安全性行为的动机来介导的。
