Social support, group consensus and stressor–strain relationships: social context matters*

Abstract In this study, we examined the degree to which individuals' reactions to stressors were influenced by the quality of their shared social environments. Based on social support theory, we proposed that individuals in positive social environments would show lower levels of strain when exposed to stressors than would individuals in negative social environments. The quality of the shared social environment was assessed by measuring the degree of consensus among group members about an issue of importance to the group—namely about the group leadership. Social influence theory provides compelling reasons to believe that this measure of consensus should be a strong indicator of the quality of the social environment within the groups. In multilevel analyses using a sample of 1923 soldiers who were members of 52 Companies deployed to Haiti, we found that the quality of the social environment moderated relationships between (a) work stressors and morale and (b) work stressors and depression.
