Agreement between veteran and partner reports of intimate partner aggression.

We examined intimate partner aggression (IPA) reporting concordance between veterans and their partners and investigated relationship satisfaction, posttraumatic stress disorder (PTSD) symptoms, and relationship attributions as correlates of IPA reporting discrepancies. The sample consisted of 239 veterans of different service eras and their intimate partners. Veterans and partners reported their physical and psychological IPA perpetration and victimization over the past 6 months. Methodological improvements over prior concordance studies included the use of clinician-assessed PTSD symptoms and the assessment of relationship attributions via observational coding of couples' conflict interactions. Results suggested low to moderate levels of agreement between veterans and partners and indicated that relationship satisfaction was associated with reporting less IPA than one's partner reported, replicating prior concordance findings. Previous concordance findings with self-reported PTSD symptoms were also reproduced in the current study using clinician-assessed PTSD symptoms. Veterans' PTSD symptoms were associated with reporting less IPA than their partners reported and partners' PTSD symptoms were associated with reporting more IPA than the veterans reported. Additionally, we found an association between relationship attributions and reporting discrepancies. For both dyad members, making more positive and less negative relationship attributions was associated with reporting less IPA than one's partner reported. Findings underscore the difficulty of obtaining objective self-reports of adverse behavior and highlight factors that may influence such reports. Clinically, this information could be used to better identify cases in which obtaining collateral reports of IPA are particularly warranted.
