BACKGROUND The incidence of suicide attempts peaks during adolescence, with adolescent girls having a higher rate of attempts than boys. Depression is one of the main risk factors of suicidal behaviour and yet not all adolescents with suicidal ideation or attempting suicide have a diagnosable depressive disorder. The present study examined the unique contributions to suicidal ideation and attempting suicide of cognitive processes known to be associated with depression and anxiety, but which are also transdiagnostic: anomalous perception of reality, intolerance of uncertainty, and rumination. METHOD 605 adolescents (M= 13.22, SD= 1.03, 47% girls) were evaluated in a cross-sectional study. RESULTS Multiple linear regression showed that the anomalous perception of reality and intolerance of uncertainty were uniquely associated with the severity of suicidal ideation, even when accounting for symptoms of depression and anxiety, but only amongst girls. In a logistic regression, self-reported depression symptoms, and not underlying cognitive processes, predicted the likelihood of a person having attempted suicide versus not having done so. CONCLUSIONS In adolescent girls, less frequently evaluated transdiagnostic variables may have an important impact on suicidal ideation. However, depression symptoms, and not these transdiagnostic variables, seem to be the greatest contributor to attempting suicide.

跨诊断变量在青少年自杀意念和自杀企图的自我报告中的性别差异中的作用。

背景自杀未遂的发生率在青春期达到高峰，青春期女孩的自杀未遂率高于男孩。抑郁症是自杀行为的主要危险因素之一，但并非所有有自杀念头或企图自杀的青少年都患有可诊断的抑郁症。本研究检查了已知与抑郁和焦虑相关的认知过程对自杀意念和企图自杀的独特贡献，但这些认知过程也是跨诊断的：对现实的异常感知、对不确定性的不容忍和反刍。方法 在一项横断面研究中评估了 605 名青少年（M=13.22，SD=1.03，47% 的女孩）。结果 多元线性回归表明，对现实的异常感知和对不确定性的不容忍与自杀意念的严重程度唯一相关，即使考虑到抑郁和焦虑的症状，但仅限于女孩。在逻辑回归中，自我报告的抑郁症状，而不是潜在的认知过程，预测了一个人试图自杀与没有自杀的可能性。结论 在青春期女孩中，较少评估的跨诊断变量可能对自杀意念产生重要影响。然而，抑郁症状，而不是这些跨诊断变量，似乎是企图自杀的最大因素。自我报告的抑郁症状，而不是潜在的认知过程，预测了一个人试图自杀与没有自杀的可能性。结论 在青春期女孩中，较少评估的跨诊断变量可能对自杀意念产生重要影响。然而，抑郁症状，而不是这些跨诊断变量，似乎是企图自杀的最大因素。自我报告的抑郁症状，而不是潜在的认知过程，预测了一个人试图自杀与没有自杀的可能性。结论 在青春期女孩中，较少评估的跨诊断变量可能对自杀意念产生重要影响。然而，抑郁症状，而不是这些跨诊断变量，似乎是企图自杀的最大因素。
