To evaluate the prevalence of suicidal ideation (SI), plans and attempts, and non-suicidal self-injury (NSSI) among students with attention deficit hyperactivity disorder (ADHD). Furthermore, we explored the mediating effects of depression, anxiety, alcohol and substance use on the association between ADHD and suicidal behaviors and NSSI.
Participants were first-year undergraduate students ( = 1,829) recruited as part of the World Mental Health International College Student Initiative. Participants completed validated clinical measures online.
The prevalence of suicide behaviors and NSSI were significantly higher among students with ADHD than those without. Mediation analyses indicated that ADHD directly and indirectly increased suicidal behaviors and NSSI. While ADHD increased suicidal behaviors and NSSI through depression, ADHD and the co-variates age and gender also had indirect effects on suicidal behaviors via substance use.
Specific predictors of risk were identified for students with ADHD which may inform the development of more targeted mental health and suicide prevention strategies across campuses.
评估注意缺陷多动障碍（ADHD）患者中自杀意念（SI）、计划和尝试以及非自杀性自我伤害（NSSI）的发生率。此外，我们探讨了抑郁、焦虑、酒精和物质使用对 ADHD 与自杀行为和 NSSI 之间关联的中介作用。
参与者为作为世界心理健康国际大学生倡议的一部分招募的一年级本科生（n=1829）。参与者在线完成了经过验证的临床测量。
与无 ADHD 的学生相比，ADHD 患者的自杀行为和 NSSI 发生率明显更高。中介分析表明，ADHD 直接和间接增加了自杀行为和 NSSI。虽然 ADHD 通过抑郁增加了自杀行为和 NSSI，但 ADHD 以及协变量年龄和性别也通过物质使用对自杀行为有间接影响。
确定了 ADHD 患者的特定风险预测因素，这可能为校园内制定更有针对性的心理健康和自杀预防策略提供信息。
