UNASSIGNED: Structural and diffusion-weighted magnetic resonance imaging (dMRI) data were acquired from 49 male veterans of the Iraq and Afghanistan wars (Operation Enduring Freedom/Operation Iraqi Freedom; OEF/OIF) of the Translational Research Center for TBI and Stress Disorders (TRACTS) study. IPV perpetration was assessed using the psychological aggression and physical assault sub-scales of the Revised Conflict Tactics Scales (CTS2). Odds ratios were calculated to assess the likelihood of IPV perpetration in veterans with either of the following diagnoses: PTSD, depression, substance use disorder, or mTBI. Fractional anisotropy tissue (FA) measures were calculated for limbic gray matter structures (amygdala-hippocampus complex, cingulate, parahippocampal gyrus, entorhinal cortex). Partial correlations were calculated between IPV perpetration, neuropsychiatric symptoms, and FA.
UNASSIGNED: Veterans with a diagnosis of PTSD, depression, substance use disorder, or mTBI had higher odds of perpetrating IPV. Greater war zone-related stress, and symptom severity of PTSD, depression, and mTBI were significantly associated with IPV perpetration. CTS2 (psychological aggression), a measure of IPV perpetration, was associated with higher FA in the right amygdala-hippocampus complex (r = 0.400, p = 0.005).
UNASSIGNED: Veterans with psychiatric disorders and/or mTBI exhibit higher odds of engaging in IPV perpetration. Further, the more severe the symptoms of PTSD, depression, or TBI, and the greater the war zone-related stress, the greater the frequency of IPV perpetration. Moreover, we report a significant association between psychological aggression against an intimate partner and microstructural alterations in the right amygdala-hippocampus complex. These findings suggest the possibility of a structural brain correlate underlying IPV perpetration that requires further research.
■结构和扩散加权磁共振成像(dMRI)数据来自TBI和应激障碍转化研究中心(TRACTS)研究的49名伊拉克和阿富汗战争(持久自由行动/伊拉克自由行动;OEF/OIF)的男性退伍军人。使用修订的冲突战术量表(CTS2)的心理侵略和人身攻击子量表评估IPV的发生率。计算赔率以评估具有以下任一诊断的退伍军人IPV发生的可能性:PTSD,抑郁症,物质使用障碍,或者mTBI.计算边缘灰质结构(杏仁核-海马复合体,扣带回,海马旁回,内嗅皮层)。计算了IPV穿透率之间的偏相关,神经精神症状,和FA。
■诊断为PTSD的退伍军人,抑郁症,物质使用障碍,或mTBI有较高的发生IPV的几率。更大的战区相关压力,和创伤后应激障碍的症状严重程度,抑郁症,mTBI与IPV感染显著相关。CTS2(心理攻击),一种IPV行为的衡量标准,与右杏仁核-海马复合体中更高的FA相关(r=0.400,p=0.005)。
■患有精神疾病和/或mTBI的退伍军人参与IPV的几率更高。Further,创伤后应激障碍的症状越严重,抑郁症,或TBI,与战区有关的压力越大,IPV渗透的频率越大。此外,我们报道了对亲密伴侣的心理攻击与右侧杏仁核-海马复合体的微结构改变之间的显著关联.这些发现表明,大脑结构可能与潜在的IPV行为相关,需要进一步研究。
