The present study examined a conceptual model in which the association between aggressive behaviors and suicide ideation is moderated by internalizing symptoms and ongoing stress. Participants were 304 psychiatric inpatient adolescents (65.8% girls) ranging in age from 12 to 17 years (Mean age = 14.69). The association between aggressive behaviors and suicide ideation was significantly moderated by internalizing symptoms and ongoing stress; the association was positive in adolescents low in internalizing symptoms or high in ongoing stress, but negative in adolescents high in internalizing symptoms or low in ongoing stress. The three-way interaction between aggressive behaviors, internalizing symptoms, and ongoing stress was not statistically significant. The current findings indicate that in adolescents who display high levels of aggressive behaviors, the presence of high ongoing stress provides a more useful indicator of levels of suicide ideation than the presence of high internalizing symptoms. Implications for case identification and prevention are discussed.
本研究检验了一个概念模型，即攻击行为与自杀意念之间的关联受到内化症状和持续压力的调节。参与者为 304 名年龄在 12 至 17 岁（平均年龄=14.69 岁）的精神科住院青少年（65.8%为女孩）。攻击行为与自杀意念之间的关联受到内化症状和持续压力的显著调节；在内化症状低或持续压力高的青少年中，这种关联呈正相关，但在内化症状高或持续压力低的青少年中，这种关联呈负相关。攻击行为、内化症状和持续压力之间的三向交互作用不具有统计学意义。目前的研究结果表明，在表现出高水平攻击行为的青少年中，高持续压力的存在比高内化症状的存在更能有效地预测自杀意念的水平。讨论了案例识别和预防的意义。
