The role of general self-efficacy in intimate partner violence and symptoms of posttraumatic stress disorder among women veterans.

Abstract

Whereas some prior studies have assessed associations between general self-efficacy, intimate partner violence (IPV) experiences, and posttraumatic stress disorder (PTSD) symptoms cross-sectionally, there is limited research investigating the potential directions of these effects or the longitudinal effects over multiple assessment points. We investigated the role of general self-efficacy in experiences of IPV and PTSD symptoms across time among 411 women veterans of the U.S. Armed Forces. Online survey data were collected at baseline (Time 1; T1), 18 months after baseline (Time 2; T2), and 2 years after baseline (Time 3; T3). Structural equation models were used to test hypotheses that T2 general self-efficacy would mediate reciprocal associations between IPV experiences and PTSD symptoms while controlling for T2 IPV experiences, T1 PTSD symptoms, and demographic and military covariates (i.e., age, military sexual trauma, and combat exposure). Specifically, we hypothesized that T2 general self-efficacy would mediate the association between (a) T1 IPV experiences and T3 IPV experiences, (b) T1 IPV experiences and T3 PTSD symptoms, (c) T1 PTSD symptoms and T3 IPV experiences, and (d) T1 PTSD symptoms and T3 PTSD symptoms. Findings revealed that T1 PTSD symptoms predicted lower T2 general self-efficacy, and, in turn, lower T2 general self-efficacy was associated with higher T3 IPV experiences, 95% CI [0.06, 0.41]; no other hypotheses were supported. The findings speak to the importance of clinical interventions which promote general self-efficacy as well as assess and treat PTSD symptoms among women who experience IPV.
