本研究采用前瞻性、纵向研究的方法，探讨了慢性环境应激源如何通过侵蚀社会支持来影响社会支持的缓冲效应。一个经典的缓冲效应的支持，发现2个月后暴露的压力，家庭拥挤。拥挤的居民低感知的支持有更大的增加心理困扰比拥挤的居民高感知的支持。然而，在暴露8个月后，缓冲作用消失。此外，更大的拥挤已经成为直接相关的低支持，这反过来又与心理困扰的增加。所有分析都控制了先前的痛苦。在某些类型的慢性压力下，社会支持的缓冲作用可能是短暂的，因为压力源最终会侵蚀社会支持。
How a chronic environmental stressor can interfere with the buffering effects of social support by eroding social support was analyzed in this prospective, longitudinal study. A classic buffering effect of support was found after 2 months of exposure to the stressor, household crowding. Crowded residents with low perceived support had greater increases in psychological distress than did crowded residents with high perceived support. However, after 8 months exposure the buffering effect disappeared. Moreover, greater crowding had become directly associated with lower support, which in turn was associated with greater increases in psychological distress. All analyses controlled for prior distress. Under some types of chronic stress, the buffering effects of social support may be short-lived because the stressor eventually erodes social support.
