Aggressive behavior and immune activity are shown to be positively associated in perpetrators of intimate partner violence (IPV). This relationship follows an inverted-U curve, with the most violent individuals showing lower levels of immunocompetence than those with a history of moderate violence. Moreover, the activational and organizational effects of testosterone (T) may indirectly stimulate the immune response. Given this, we used the Trier Social Stress Test to establish whether the salivary immunoglobulin A (sIgA) response to acute stress was a specific psychobiological feature in perpetrators of intimate partner violence (IPV). IPV perpetrators showed higher sIgA levels than controls for the preparation period. Moreover, higher anger expression and T (baseline and AUCi) were only related to higher sIgA levels in IPV perpetrators. We hypothesize that in IPV perpetrators, the use of violence against partners could benefit their psychological well-being - through immunological modifications such as mucosal immunity changes expressed by the sIgA - and so be rewarding for them. This research may provide a wider explanation of why IPV perpetrators use violence against their partners.
攻击性行为和免疫活性被证明与亲密伴侣暴力（IPV）的施害者呈正相关。这种关系遵循一个倒 U 型曲线，最暴力的个体表现出比有中度暴力史的个体更低的免疫能力。此外，睾酮（T）的激活和组织效应可能会间接刺激免疫反应。鉴于此，我们使用特里尔社会应激测试来确定唾液免疫球蛋白 A（sIgA）对急性应激的反应是否是亲密伴侣暴力（IPV）施害者的特定心理生物学特征。与对照组相比，IPV 施害者在准备期的 sIgA 水平更高。此外，较高的愤怒表达和 T（基线和 AUCi）仅与 IPV 施害者的 sIgA 水平升高有关。我们假设，在 IPV 施害者中，对伴侣使用暴力可能会通过免疫调节（如黏膜免疫变化表达的 sIgA）有益于他们的心理健康，因此对他们来说是有益的。这项研究可能为为什么 IPV 施害者对其伴侣使用暴力提供了更广泛的解释。
