Abstract

This study examined the mediating role of posttraumatic stress disorder (PTSD) symptoms in the association between deployment-related trauma exposure and parenting behaviors in reserve-component military service members and whether this association was contingent upon parent inhibitory control (IC). Participants were 181 postdeployed fathers and their children. Fathers completed a neurospychological test of IC and self-report measures of trauma exposure and PTSD symptoms. Measures of parenting behaviors (positive engagement and reactivity coercion) were obtained from direct observation of father-child interaction. Results demonstrated that (a) fathers' PTSD symptoms indirectly mediated the effect of trauma exposure on both measures of parenting (i.e., negative indirect effect for positive engagement, point estimate = -.0045, 95% CI [-.0107, -.0003], and positive indirect effect for reactivity coercion, point estimate = .0061, 95% CI [.0007, .0146]); (b) fathers' IC skills moderated the association between trauma exposure and PTSD, β = .14, p = .043, such that the association was positive and significant for fathers with high and medium IC but nonsignificant for fathers with low IC; and (c) the indirect effect of trauma exposure...Continue Reading
