The authors conducted a meta-analysis of empirical studies investigating associations between indices of posttraumatic stress disorder (PTSD) and intimate relationship problems to empirically synthesize this literature. A literature search using PsycINFO, Medline, Published International Literature on Traumatic Stress (PILOTS), and Dissertation Abstracts was performed. The authors identified 31 studies meeting inclusion criteria. True score correlations (ρ) revealed medium-sized associations between PTSD and intimate relationship discord (ρ = .38, N = 7,973, K = 21), intimate relationship physical aggression perpetration (ρ = .42, N = 4,630, K = 19), and intimate relationship psychological aggression perpetration (ρ = .36, N = 1,501, K = 10). The strength of the association between PTSD and relationship discord was higher in military (vs. civilian) samples, and when the study was conducted in the United States (vs. other country), and the study represented a doctoral dissertation (vs. published article). The strength of the association between PTSD and physical aggression was higher in military (vs. civilian) samples, males (vs. females), community (vs. clinical) samples, studies examining PTSD symptom severity (vs. diagnosis), when the physical aggression measure focused exclusively on severe violence (vs. a more inclusive measure), and the study was published (vs. dissertation). For the PTSD-psychological aggression association, 98% of the variance was accounted for by methodological artifacts such as sampling and measurement error; consequently, no moderators were examined in this relationship. Findings highlight a need for the examination of models explaining the relationship difficulties associated with PTSD symptomatology and interventions designed to treat problems in both areas.

This study examined the association between posttraumatic stress disorder (PTSD) symptomatology and aggressive behavior among a sample of male Vietnam veterans (N = 1,328). Results indicated that the hyperarousal PTSD symptom cluster evidenced the strongest positive association with aggression at the bivariate level when compared with the other PTSD symptom clusters. When the PTSD symptom clusters were examined together as predictors, hyperarousal symptoms evidenced a significant positive relationship with aggression, and avoidance/numbing symptoms were negatively associated with aggression. Examination of potential mediators indicated that hyperarousal symptoms were directly associated with aggression and indirectly related to aggression via alcohol problems. Reexperiencing symptoms were associated with aggression only indirectly and through their positive association with physiological reactivity and negative association with alcohol problems. Study results highlight the complexity of the relationship between PTSD symptoms and aggression, and suggest possible mechanisms explaining this association.

The authors examined interrelationships among posttraumatic stress disorder (PTSD) symptomatology, anger, and partner abuse perpetration among a sample of 60 combat veterans. Compared with PTSD-negative participants, PTSD-positive participants reported higher state anger across time and neutral and trauma prime conditions and higher anger reactivity during the trauma prime condition. PTSD-positive participants also exhibited more anger reactivity during the trauma prime than during the neutral condition. The same pattern of results was not found for anxiety reactivity during trauma memory activation. PTSD symptoms were associated with physical assault and psychological aggression perpetration, and trait anger mediated these relationships. Findings indicate a heightened anger response among PTSD-positive veterans and suggest the salience of dispositional components of anger in abuse perpetration in this population.

In this study, the authors examined the interrelations among family-of-origin maltreatment variables, posttraumatic stress disorder (PTSD) symptoms, social information processing deficits, and male-to-female psychological and physical intimate relationship abuse perpetration in adulthood among a community sample of 164 men and their partners. In bivariate analyses, higher family-of-origin childhood parental rejection was associated with the perpetration of psychological and physical abuse in adulthood, and childhood exposure to interparental violence was also associated with adult psychological abuse perpetration. Structural equation modeling analyses indicated that when childhood variables and other study variables were considered together, only childhood parental rejection was associated with the abuse perpetration outcomes, and these effects were indirect through PTSD symptoms and social information processing deficits. Results indicate a need for further investigation into the mechanisms accounting for the impact of early maltreatment on the development of abusive intimate relationship behavior.
