Abstract

BACKGROUND

Most studies have shown that negative life events and social support are important factors in the development and outcome of depression. It is unknown if these factors are important in adolescents with subthreshold depression. Thus, the current study examined whether high levels of social support from peers buffer adolescents exhibiting subthreshold depressive symptoms against experiencing further increases in such symptoms following the occurrence of negative events.

METHODS

Participants included 143 adolescents (aged 14 to 18; M=16.07, SD=.66) in Hunan Province China who were selected because they were exhibiting subthreshold depressive symptoms at the time of initial assessment. During an initial assessment, participants completed measures assessing social support from peers and depressive symptoms. Participants subsequently completed measures assessing depressive symptoms and the occurrence of negative events once every three months for the subsequent fifteen months.

RESULTS

The prevalence of lifetime subthreshold depression in Hunan was 22.9% (n=143). The results of hierarchical linear modeling analyses indicated that lower levels of social support from peers was associated with greater increases in depressive symptoms following the occurrence of negative events.

CONCLUSIONS

The results suggested that the association between the occurrence of negative events and increased depressive symptoms is moderated by social support from peers in adolescents with subthreshold depression in mainland China, in line with the buffering hypothesis.

LIMITATIONS

The adolescent sample used in the current study was from Hunan, China, which could limit the generalizability of our results to other populations. In addition, given that it is possible that cultural context shapes symptom manifestation, future research should assess a broader array of symptom outcomes.

摘要

背景

大多数研究表明,负性生活事件和社会支持是抑郁发生和转归的重要因素。目前尚不清楚这些因素在阈下抑郁的青少年中是否重要。因此,本研究旨在探讨同伴的高社会支持水平是否能缓冲表现出阈下抑郁症状的青少年在经历负性生活事件后进一步增加此类症状。

方法

参与者包括湖南省 143 名年龄在 14 至 18 岁(M=16.07,SD=.66)的青少年,他们在初次评估时表现出阈下抑郁症状。在初次评估中,参与者完成了评估同伴社会支持和抑郁症状的量表。随后,参与者在接下来的 15 个月中每三个月完成一次评估抑郁症状和负性生活事件发生情况的量表。

结果

湖南省阈下抑郁症的终身患病率为 22.9%(n=143)。分层线性模型分析的结果表明,同伴社会支持水平较低与负性生活事件发生后抑郁症状的增加有关。

结论

研究结果表明,在中国大陆阈下抑郁的青少年中,负性生活事件与抑郁症状增加之间的关联受到同伴社会支持的调节,这与缓冲假设一致。

局限性

本研究中使用的青少年样本来自中国湖南,这可能限制了我们研究结果在其他人群中的推广。此外,鉴于文化背景可能会影响症状表现,未来的研究应该评估更广泛的症状结果。
