不良的生理自我调节被认为是青少年自杀的潜在生物脆弱性。本研究通过研究副交感神经应激反应对未来自杀意念的影响来验证这一假设。此外，从多层次的发展心理病理学理论，副交感神经调节和友谊支持，概念化的外部来源的监管之间的相互作用进行了检查。在基线时，132名有精神健康问题史的青少年女性（M年龄= 14.59，SD = 1.39）参加了体内人际压力源（实验室言语任务），并完成了抑郁症状的自我报告措施，并在密切的同龄女性友谊中感知支持。呼吸性窦性心律失常（RSA）之前和期间的讲话任务进行了测量。在基线和3、6和9个月随访时评估自杀意念。结果显示，女性与更大的相对RSA减少到实验室的压力，在随后的9个月报告自杀意念的风险较高。此外，副交感神经反应缓和的影响，友谊支持自杀意念;在女性中，轻微的变化或较高的相对增加RSA，但没有更明显的RSA下降，友谊支持降低风险，为未来的自杀意念。研究结果强调了生理和外部调节源作为青年自杀的保护因素的重要作用。
Poor physiological self-regulation has been proposed as a potential biological vulnerability for adolescent suicidality. This study tested this hypothesis by examining the effect of parasympathetic stress responses on future suicide ideation. In addition, drawing from multilevel developmental psychopathology theories, the interplay between parasympathetic regulation and friendship support, conceptualized as an external source of regulation, was examined. At baseline, 132 adolescent females (M age = 14.59, SD = 1.39) with a history of mental health concerns participated in an in vivo interpersonal stressor (a laboratory speech task) and completed self-report measures of depressive symptoms and perceived support within a close same-age female friendship. Respiratory sinus arrhythmia (RSA) was measured before and during the speech task. Suicide ideation was assessed at baseline and at 3, 6, and 9 months follow-up. The results revealed that females with greater relative RSA decreases to the laboratory stressor were at higher risk for reporting suicide ideation over the subsequent 9 months. Moreover, parasympathetic responses moderated the effect of friendship support on suicide ideation; among females with mild changes or higher relative increases in RSA, but not more pronounced RSA decreases, friendship support reduced risk for future suicide ideation. Findings highlight the crucial role of physiological and external regulation sources as protective factors for youth suicidality.
