Few studies have examined the link between anxiety sensitivity (AS) and suicidality among adolescents with major depressive disorder; thus, there is a need to explore this relationship in order to fill the research gap. The aim of this cross-sectional study was to examine the association among AS and suicidal behaviour while taking into account the effects of potential third variables such as the presence of anxiety disorders and hopelessness in adolescents with major depressive disorder.
Participants (n=101) completed self-report measures of depressive symptoms, AS, hopelessness and suicidal ideation severity. The presence of anxiety disorders and suicide attempt history were determined with psychiatric interviews. The association between psychiatric variables was evaluated using structural equation modelling.
Results showed that AS cognitive concerns had a positive effect on suicidal ideation mediated by the severity of depression. AS physical concerns had a negative direct effect on suicidal ideation, but there was also a positive relationship among these variables through hopelessness, thus, the total effect of AS physical concerns was not significant. There were also positive relationships between hopelessness and suicidal ideation, and the presence of anxiety disorders to suicide attempt history.
The results of this study suggest that higher AS cognitive concerns may be a risk factor for suicidality through the severity of depression in adolescents who are diagnosed with major depressive disorder.
很少有研究探讨重度抑郁症青少年的焦虑敏感性（AS）与自杀倾向之间的联系；因此，有必要探索这种关系以填补研究空白。这项横断面研究的目的是在考虑潜在第三变量（如重度抑郁症青少年中焦虑症的存在和绝望感）影响的情况下，检验AS与自杀行为之间的关联。
参与者（n = 101）完成了关于抑郁症状、AS、绝望感和自杀意念严重程度的自我报告测量。通过精神科访谈确定焦虑症的存在和自杀未遂史。使用结构方程模型评估精神科变量之间的关联。
结果显示，AS认知担忧通过抑郁严重程度对自杀意念产生积极影响。AS身体担忧对自杀意念有负面直接影响，但这些变量之间通过绝望感也存在正相关关系，因此，AS身体担忧的总体影响不显著。绝望感与自杀意念之间以及焦虑症的存在与自杀未遂史之间也存在正相关关系。
本研究结果表明，对于被诊断为重度抑郁症的青少年，较高的AS认知担忧可能通过抑郁严重程度成为自杀倾向的一个风险因素。
