In a 10-year follow-up of a survey from Oslo, 503 persons were reinterviewed using the same questionnaire.
The questionnaire includes information about social support, 'locus of control' and mental health as well as negative life events and long-lasting mental strain during the year prior to the follow-up.
The study confirms the "buffer hypothesis", that social support protects against the development of mental disorder only when the individual is exposed to stressors, like negative life events. This buffering effect was especially strong for depression.
The buffering effect only applies to the 'externals'--those who have personality-related feelings of powerlessness and lack of control over their own lives. The 'internals' do not have the same need for social support to cope with life stressors, and have low symptom scores even when negative life events are combined with relative weak social support.
在对奥斯陆一项调查进行的10年随访中,使用相同问卷对503人进行了再次访谈。
该问卷包含有关社会支持、“控制点”、心理健康以及随访前一年中的负面生活事件和长期精神压力的信息。
该研究证实了“缓冲假说”,即只有当个体暴露于诸如负面生活事件等压力源时,社会支持才能预防精神障碍的发生。这种缓冲效应在抑郁症方面尤为明显。
缓冲效应仅适用于“外部者”——那些在性格上感到无助且对自己生活缺乏掌控感的人。“内部者”在应对生活压力源时对社会支持的需求不同,即使负面生活事件与相对薄弱的社会支持同时存在,他们的症状得分也较低。
