A model to explain the relationship between sexual abuse and HIV risk among women.

This paper presents a model developed to advance the understanding of the relationship between sexual abuse and HIV risk among women. It is proposed that the relationship is mediated by many of the long-term sequelae of sexual abuse. The process of mediation is believed to occur through various causal pathways propelled by specific underlying mechanisms that increase the likelihood of HIV risk. The following causal pathways are proposed: (1) initiation of and/or increasing reliance on drug use as a method of coping with the sexual abuse experience, (2) problems with sexual adjustment related to sex risk taking, and (3) psychopathology (e.g. depression) which increases the likelihood of an individual participating in HIV risk behaviours. These hypothesized pathways are based on the characteristics and behaviours of individuals with histories of sexual abuse and do not take into account the influence of the individual's social environment. Increasingly, evidence suggests that understanding the social context of HIV risk is crucial to the development of preventive interventions. Therefore, a final pathway is explored which suggests that specific social network characteristics (e.g. network membership type, social support, and social isolation) influence HIV risk exposure opportunities among women with sexual abuse histories.
