The influence of state and trait affect on HIV risk behaviors: a daily diary study of MSM
1University of Illinois at Chicago, IL 60608, USA. bmustanski@psych.uic.edu
Objective:
To characterize the influence of state and trait affect on HIV risk behaviors.
Design:
Men who have sex with men (N = 155) completed reports of trait affect and daily reports of affect and sexual behaviors each night for up to 30 days.
Main Outcome Measures:
Analyses focused on the role of state and trait positive activation (PA), negative activation (NA), anxious arousal (AA), and sexual activation (SA) on sexual risk taking, operationalized as having a sex partner, a partner-related risk composite, and an HIV risk behavior composite.
Results:
State SA was positively associated with having a sex partner and HIV risk behaviors; trait SA was positively associated with partner-related risk. State AA was negatively associated with having a sex partner and positively associated with HIV risk behaviors. Trait AA had a negative association with partner-related risk and moderated the effects of state AA. State PA was negatively associated with HIV risk behaviors, and trait PA had a main effect on having a sex partner. NA had no significant trait or state effects.
Conclusion:
These data suggest a role for multiple affective states in sexual risk taking. Models of HIV risk-taking behaviors should be extended to include affective processes.
