The objective of this study was to investigate the contributions of mental health status and attitudes towards suicide on suicidal ideation in a sample of 6568 Chinese children and adolescents in China. Attitudes towards suicide were investigated as a possible moderator and mediator of the influence of mental health status on suicidal ideation.
Descriptive statistical analyses, Pearson correlation analyses and hierarchical regression analyses were adopted as methods of data analyses.
Approximately 35.38% of children and adolescents in our study reported having suicidal ideation. Mental health status and attitudes towards suicide both had an independent effect on the severity of suicidal ideation. Results indicated that mental health status was positively associated with suicidal ideation, while attitudes towards suicide were negatively associated with suicidal ideation. Moderation analysis showed that the impact of mental health status on suicidal ideation was significantly greater among children and adolescents who reported favourable attitudes towards suicide. Attitudes towards suicide partially mediated the link between mental health status and the severity of suicidal ideation. Specifically, students who experienced poorer mental health status might be more likely to report significantly more favourable attitudes towards suicide, which in turn promote greater suicidal ideation.
These results have implications for the prevention of youth suicide, suggesting that mental health status and attitudes towards suicide could be important targets for prevention and intervention for children and adolescents at risk of suicidal ideation.
本研究的目的是在中国6568名儿童和青少年样本中，调查心理健康状况和对自杀的态度对自杀意念的影响。对自杀的态度被作为心理健康状况对自杀意念影响的一个可能的调节变量和中介变量进行研究。
采用描述性统计分析、Pearson相关分析和分层回归分析作为数据分析方法。
在我们的研究中，约35.38%的儿童和青少年报告有自杀意念。心理健康状况和对自杀的态度均对自杀意念的严重程度有独立影响。结果表明，心理健康状况与自杀意念呈正相关，而对自杀的态度与自杀意念呈负相关。调节分析表明，在对自杀持积极态度的儿童和青少年中，心理健康状况对自杀意念的影响显著更大。对自杀的态度部分中介了心理健康状况与自杀意念严重程度之间的联系。具体而言，心理健康状况较差的学生可能更有可能报告对自杀明显更积极的态度，这反过来又会促使产生更强的自杀意念。
这些结果对预防青少年自杀具有启示意义，表明心理健康状况和对自杀的态度可能是有自杀意念风险的儿童和青少年预防和干预的重要目标。
