Suicidal behaviour is one of the main causes of death worldwide, especially among teenagers, and its development is potentially associated with the development of personality. The aim of this systematic review and meta-analysis is to describe the association between the Big Five Personality Traits and suicidal behaviour in adolescents.
Seven databases were systematically searched between June 2022 and July 2022 with no language or year restrictions. We searched for a combination of the following search items (suicid* OR suicidal behaviour OR suicidal ideation OR suicide attempts OR self injury OR self-destructive behaviour OR self-harm OR suicidal risk) AND (personality OR personality traits OR temperament OR neuroticism OR extraversion OR agreeableness OR openness to experience OR conscientiousness) AND (adolescents OR youth OR teenagers OR young adults). Meta-analysis procedures were performed using the R software. A random-effect-model was performed for the models through the incorporation of τ, based on the DerSimonion Lard method.
Seven studies met all inclusion criteria and were included in this systematic review. Our meta-analysis showed that higher neuroticism are both associated and a risk factor for suicidal behaviour. Higher levels of openness to experience and agreeableness, and lower levels of extraversion and conscientiousness, were linked to suicidal behaviour, especially self-harm.
Due to the heterogeneity of the studies, we were only able to perform meta-analysis regarding neuroticism.
The present study may help professionals to identify adolescents in higher risk for suicidal behaviour, enabling the development of early interventions to prevent suicidality in this population.
自杀行为是全球主要死因之一，在青少年中尤为突出，其发展可能与人格发展有关。本系统评价和荟萃分析的目的是描述青少年大五人格特质与自杀行为之间的关联。
于2022年6月至2022年7月期间对七个数据库进行了系统检索，无语言或年份限制。我们搜索了以下搜索词的组合（自杀*或自杀行为或自杀意念或自杀未遂或自我伤害或自我毁灭行为或自我伤害或自杀风险）以及（人格或人格特质或气质或神经质或外向性或宜人性或经验开放性或尽责性）以及（青少年或青年或十几岁青少年或年轻人）。使用R软件进行荟萃分析程序。基于DerSimonion Lard方法，通过纳入τ对模型进行随机效应模型分析。
七项研究符合所有纳入标准，被纳入本系统评价。我们的荟萃分析表明，较高的神经质既是自杀行为的相关因素，也是危险因素。较高的经验开放性和宜人性水平，以及较低的外向性和尽责性水平，与自杀行为有关，尤其是自我伤害。
由于研究的异质性，我们仅能对神经质进行荟萃分析。
本研究可能有助于专业人员识别自杀行为风险较高的青少年，从而制定早期干预措施以预防该人群中的自杀行为。
