Depression is a common mental disorder among adolescents, characterized by a high rate of suicide and self-harm, which not only is devastating to families but also has a negative impact on society. Psychological factors such as impulsive personality, perceived chronic social adversity (PCSA), and sense of security are closely associated with suicide risk in adolescents with depression. Few studies have been conducted on the relationship between these factors.
To explore the impact of impulsive personality on suicide risk in adolescents with depression and the chain mediating effect between PCSA and sense of security.
This study is a retrospective study. A total of 200 adolescents with depression who visited the Guangxi Zhuang Autonomous Region Maternal and Child Health Hospital from January 2021 to December 2023 comprised the study cohort. The PCSA scale, Security Questionnaire, Barratt Impulsiveness Scale, and Beck Scale for Suicide Ideation were used to evaluate depression.
Suicide risk was positively correlated with impulsive personality and PCSA ( < 0.05), whereas sense of security was negatively correlated with suicide risk, impulsive personality, and PCSA ( < 0.05). The total indirect effect of PCSA and sense of security on impulsive personality and suicide risk was 35.43%, with the mediating effect of PCSA and sense of security contributing 16.53% and 15.75%, respectively. PCSA and sense of security exhibited a chain mediating effect between impulsive personality and suicide risk, accounting for 3.15%.
The suicide risk of adolescents with depression is significantly associated with impulsive personality, PCSA, and sense of security. Impulsive personality affects the suicide risk of adolescents with depression both directly and indirectly, with the latter occurring PCSA and sense of security.
抑郁症是青少年常见的精神障碍，其自杀和自我伤害发生率高，不仅对家庭具有毁灭性，而且对社会有负面影响。冲动型人格、感知到的长期社会逆境（PCSA）和安全感等心理因素与抑郁症青少年的自杀风险密切相关。关于这些因素之间的关系，鲜有研究。
探讨冲动型人格对抑郁症青少年自杀风险的影响以及PCSA与安全感之间的链式中介作用。
本研究为回顾性研究。选取2021年1月至2023年12月在广西壮族自治区妇幼保健院就诊的200例抑郁症青少年组成研究队列。采用PCSA量表、安全感问卷、巴雷特冲动性量表和贝克自杀意念量表评估抑郁情况。
自杀风险与冲动型人格和PCSA呈正相关（<0.05），而安全感与自杀风险、冲动型人格和PCSA呈负相关（<0.05）。PCSA和安全感对冲动型人格和自杀风险的总间接效应为35.43%，其中PCSA和安全感的中介效应分别为16.53%和15.75%。PCSA和安全感在冲动型人格和自杀风险之间表现出链式中介作用，占比3.15%。
抑郁症青少年的自杀风险与冲动型人格、PCSA和安全感显著相关。冲动型人格直接和间接影响抑郁症青少年的自杀风险，后者通过PCSA和安全感发生。
