The occurrence and degree of suicidal ideation during the past month in adolescents should be regarded seriously. Several studies have noted that humor expression style and depressive emotion may influence adolescents’ suicidal ideation. However, there is insufficient evidence concerning whether positive emotion reduces such suicidal ideation in adolescents. In addition, the relationships among humor expression, depressive emotion, positive emotion and suicidal ideation remain to be confirmed. Therefore, in this study, we aimed to test the mediating roles of depressive emotion and positive emotion in the relationship between humor expression and recent adolescent’s suicidal ideation. A total of 1551 students in junior high school completed questionnaires. The collected data were analyzed using structural equation modeling (SEM) with LISREL 8.80 and Monte Carlo resampling with R. The results indicate that suicidal ideation in adolescents during the past month was related not only to humor expression but also to depressive emotion and positive emotion. The stronger the depressive emotion felt, the stronger the suicidal ideation; in contrast, the stronger the positive emotion, the weaker the suicidal ideation. Moreover, depressive emotion and positive emotion were found to mediate the relationship between humor expression and suicidal ideation; additionally, positive emotion was found to mediate the relationship between depressive emotion and suicidal ideation. These results highlight that depressive emotion and positive emotion may mediate the influence of humor expression on suicidal ideation among adolescents, and positive emotion may mediate the influence of depressive emotion on suicidal ideation. More attention should be paid to decreasing adolescents’ self-deprecating humor expression and depressive emotion, whereas more witty response humor expression and positive emotion should be encouraged to prevent their suicidal ideation.

幽默表达对青少年自杀意念的影响：抑郁情绪和积极情绪的中介作用。

在过去的一个月中，青少年自杀意念的发生和程度应予以认真考虑。多项研究指出，幽默的表达方式和抑郁情绪可能会影响青少年的自杀意念。但是，没有足够的证据证明积极情绪是否会减少青少年的这种自杀念头。此外，幽默表达，抑郁情绪，积极情绪和自杀意念之间的关系仍有待确认。因此，在这项研究中，我们旨在检验抑郁情绪和积极情绪在幽默表达与青少年自杀意念之间的中介作用。共有1551名初中学生填写了问卷。使用LISREL 8使用结构方程模型（SEM）分析收集的数据。80和蒙特卡洛用R重新采样。结果表明，过去一个月的青少年自杀意念不仅与幽默表达有关，而且与抑郁情绪和积极情绪有关。抑郁情绪越强烈，自杀意念就越强烈。相反，积极情绪越强，自杀意念就越弱。此外，还发现抑郁情绪和积极情绪可以调节幽默表达与自杀意念之间的关系。另外，发现积极情绪可以介导抑郁情绪与自杀意念之间的关系。这些结果表明，抑郁情绪和积极情绪可能会介导幽默表达对青少年自杀意念的影响，积极情绪可能会介导抑郁情绪对自杀意念的影响。应更多地注意减少青少年自嘲的幽默表达和抑郁情绪，而应鼓励更多机智的幽默表达和积极情绪，以防止他们自杀意念。
