Persons with autism spectrum disorders (ASDs) are suggested to have an increased risk for suicide ideation and suicide attempts, but this topic is largely understudied. Research indicates that temperament and character traits are associated with suicidal behavior in persons without ASD, with higher scores for novelty seeking (NS), harm avoidance (HA), and self‐transcedence (ST), and lower scores for self‐directedness (SD) and cooperativeness (CO). Usually persons with ASD have temperament and character profiles with high HA, and low NS, reward dependence (RD), SD, and CO. The aim is to investigate whether there is a relationship between temperament and character traits and suicide ideation and attempts in adults with ASD. Seventy‐four adults with ASD participated by completing self‐report measures on suicide thoughts and behavior, depression, and temperament. Independent sample t‐tests were conducted to compare scores between attempters versus nonattempters and between ideators versus nonideators. Regression analysis was performed to explore the predictive value of temperament and character. T‐tests showed lower NS and SD, and higher HA for ideators versus nonideators, but not for attempters versus nonattempters. Regression models showed no significant relation between suicide ideation and NS, SD, HA after the latter were controlled for the significant influence of depression. Temperament and character can probably not be used for predicting suicide ideation and attempts, based on results from the current sample. Clinicians must take note of the high prevalence and risk of depression among persons with ASD, which may be under‐reported.

气质和性格是自闭症谱系障碍成年人自杀意念和尝试的危险因素。

建议患有自闭症谱系障碍（ASD）的人自杀意念和自杀企图的风险增加，但是这个话题在很大程度上未被研究。研究表明，气质和性格特征与无ASD的人的自杀行为有关，新奇（NS），伤害避免（HA）和自我超越（ST）得分较高，自我指导（SD）得分较低）和合作性（CO）。通常，患有ASD的人的气质和性格特征具有高HA，低NS，奖励依赖（RD），SD和CO。目的是研究成年人的气质和性格特征与自杀意念和尝试之间是否存在关系使用ASD。74名成人自闭症患者参加了有关自杀思想和行为，抑郁，和气质。独立样本进行t检验以比较尝试者与非尝试者之间以及思想者与非思想者之间的得分。进行回归分析以探究气质和性格的预测价值。T检验显示，与非参议员相比，思想者与非参议员的NS和SD较低，HA较高。回归模型显示自杀意念与NS，SD，HA在抑郁受显着影响控制后没有显着关系。根据当前样本的结果，气质和性格可能无法用于预测自杀意念和尝试。临床医生必须注意自闭症患者的高患病率和抑郁风险，这可能被低估了。自闭症2020，13：104–111。©2019国际自闭症研究会，Wiley Periodicals，Inc.
