To expand the scientific literature on how resting state functional connectivity (rsFC) magnetic resonance imaging (MRI) (or the measurement of the strength of the coactivation of two brain regions over a sustained period of time) can be used to explain treatment compliance and recidivism among intimate partner violence (IPV) perpetrators. Therefore, our first aim was to assess whether men convicted of IPV (n = 53) presented different rsFC patterns from a control group of non-violent (n = 47) men. We also analyzed if the rsFC of IPV perpetrators before staring the intervention program could explain treatment compliance and recidivism one year after the intervention ended. The rsFC was measured by applying a whole brain analysis during a resting period, which lasted 45 min. IPV perpetrators showed higher rsFC in the occipital brain areas compared to controls. Furthermore, there was a positive association between the occipital pole (OP) and temporal lobes (ITG) and a negative association between the occipital (e.g., occipital fusiform gyrus, visual network) and both the parietal lobe regions (e.g., supramarginal gyrus, parietal operculum cortex, lingual gyrus) and the putamen in IPV perpetrators. This pattern was the opposite in the control group. The positive association between many of these occipital regions and the parietal, frontal, and temporal regions explained treatment compliance. Conversely, treatment compliance was also explained by a reduced rsFC between the rostral prefrontal cortex and the frontal gyrus and both the occipital and temporal gyrus, and between the temporal and the occipital and cerebellum areas and the sensorimotor superior networks. Last, the enhanced rsFC between the occipital regions and both the cerebellum and temporal gyrus predicted recidivism. Our results highlight that there are specific rsFC patterns that can distinguish IPV perpetrators from controls. These rsFC patterns could be useful to explain treatment compliance and recidivism among IPV perpetrators.
为了扩展关于静息态功能连接（rsFC）磁共振成像（MRI）（或测量两个脑区在持续时间内的协同激活强度）如何用于解释亲密伴侣暴力（IPV）施害者的治疗依从性和复发率的科学文献，因此，我们的首要目标是评估是否有被定罪的 IPV 男性（n=53）与非暴力男性（n=47）表现出不同的 rsFC 模式。我们还分析了 IPV 施害者在开始干预计划之前的 rsFC 是否可以解释干预结束一年后的治疗依从性和复发率。rsFC 通过在静息期进行全脑分析来测量，静息期持续 45 分钟。与对照组相比，IPV 施害者的枕叶大脑区域显示出更高的 rsFC。此外，枕叶极（OP）与颞叶（ITG）之间存在正相关，枕叶（例如，枕叶梭状回、视觉网络）与顶叶区域（例如，缘上回、顶叶脑岛皮质、舌回）和纹状体之间存在负相关。在对照组中，这种模式则相反。许多这些枕叶区域与顶叶、额叶和颞叶之间的正相关与治疗依从性相关。相反，治疗依从性还与额前皮质与额上回之间、以及颞叶与枕叶和小脑之间、以及感觉运动上网络之间 rsFC 的减少相关。最后，枕叶区域与小脑和颞叶之间增强的 rsFC 预测了复发。我们的结果强调了存在特定的 rsFC 模式，可以将 IPV 施害者与对照组区分开来。这些 rsFC 模式可用于解释 IPV 施害者的治疗依从性和复发率。
