title: The influence of state and trait affect on HIV risk behaviors: a daily diary study of MSM.
abstract: OBJECTIVE
  To characterize the influence of state and trait affect on HIV risk behaviors.
  
  
  METHODS
  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.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  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.
