Suicide among elementary school-age youth is vastly understudied despite being a major health concern. This study utilized mediation and moderation models to elucidate the nature of risk factors for suicide by examining the effect emotion dysregulation (of anger, sadness, and worry) has on the relation between ADHD symptoms (hyperactivity/impulsivity and inattention) and suicidal outcomes (suicidal behavior and risk for suicide) in children ages 6 to 12. When accounting for sex, age, depressive symptoms, and emotion dysregulation, hyperactivity/impulsivity was positively associated with suicidal behavior; however, inattention was negatively associated with suicidal behavior. After accounting for the variance associated with sex, age, and depressive symptoms, two interaction effects were evident. At low levels of sadness and worry dysregulation, hyperactivity was positively associated with suicide risk. However, at high levels of sadness and worry dysregulation, hyperactivity was not related to suicide risk. Findings support moderation over mediation.
尽管小学生自杀是一个重大的健康问题，但对其研究却极为不足。本研究运用中介和调节模型，通过考察情绪失调（愤怒、悲伤和担忧）对6至12岁儿童多动症症状（多动/冲动和注意力不集中）与自杀结果（自杀行为和自杀风险）之间关系的影响，来阐明自杀风险因素的本质。在考虑性别、年龄、抑郁症状和情绪失调后，多动/冲动与自杀行为呈正相关；然而，注意力不集中与自杀行为呈负相关。在考虑与性别、年龄和抑郁症状相关的方差后，有两个交互作用明显。在悲伤和担忧失调水平较低时，多动与自杀风险呈正相关。然而，在悲伤和担忧失调水平较高时，多动与自杀风险无关。研究结果支持调节作用而非中介作用。
