研究了社会支持和压力对抑郁症的影响（社会支持的“缓冲效应”）的全球措施的统计相互作用的共同解释，反映了个人内部的互动过程。有人认为，它的充分性取决于不正确的假设，随着时间的推移和/或不同程度的心理社会逆境的个人内的抑郁症状的分布。与假设的阈值效应下产生的假设数据集抑郁症的发展和添加剂，而不是互动，社会支持和压力的影响，它表明，虚假的“缓冲效应”的社会支持，可以出现在横截面数据的分析。方法和实质性的影响进行了讨论，并提出了研究设计和数据分析的策略，允许评估是否从线性的经验偏差更充分地解释为缓冲区或阈值效应。
The common interpretation of statistical interactions of global measures of social support and stress in their effects on depression (the "buffer effect" of social support) as reflecting interactive processes within individuals was examined. It was argued that its adequacy depends on incorrect assumptions about the distribution of depressive symptoms within individuals over time and/or different levels of psychosocial adversity. With hypothetical data sets generated under the assumption of a threshold effect in the development of depression and of additive, rather than interactive, effects of social support and stress, it was demonstrated that spurious "buffer effects" of social support can appear in analyses of cross-sectional data. Methodological and substantive implications are discussed, and strategies for study design and data analysis are proposed that allow to assess whether empirical deviations from linearity are more adequately interpreted as a buffer or as a threshold effect.
