This study examined the association between cognitive control capacities, suicidal thoughts and attempts, and depressive symptoms during late adolescence and young adulthood. The sample included 4192 participants (55.5% female) from the United States who participated in Waves III (2001-2002; respondent age 18-26 years) and IV (2007-2008; respondent age 24-33 years) of the National Longitudinal Study of Adolescent to Adult Health. Data were analyzed using structural equation modeling. Suicidality in late adolescence predicted depressive symptoms in young adulthood. Depressive symptoms were not predictive of later suicide ideation nor attempts. Working memory was associated with lower depressive symptoms. Higher verbal ability was associated with more suicidal thoughts but not attempts. Internal locus of control was associated with decreased depressive symptoms and suicidal thoughts/attempts in young adulthood. Findings suggest that cognitive control capacities developed in adolescence differentially predict depressive symptoms, suicidal thoughts, and suicide attempts in young adulthood.
本研究考察了认知控制能力、自杀意念和尝试，以及青少年晚期和成年早期的抑郁症状之间的关联。该样本包括来自美国的 4192 名参与者（女性占 55.5%），他们参加了美国国家青少年至成人健康纵向研究的第三波（2001-2002 年；受访者年龄 18-26 岁）和第四波（2007-2008 年；受访者年龄 24-33 岁）。数据采用结构方程模型进行分析。青少年晚期的自杀倾向预测了成年早期的抑郁症状。抑郁症状不能预测后来的自杀意念或尝试。工作记忆与较低的抑郁症状有关。较高的语言能力与更多的自杀想法有关，但与自杀尝试无关。内部控制源与成年早期抑郁症状和自杀想法/尝试的减少有关。研究结果表明，青少年时期发展起来的认知控制能力对成年早期的抑郁症状、自杀想法和自杀尝试有不同的预测作用。
