Stress,health, and reciprocity and sufficiency of social support: the case of university students in Japan

The authors examined the effects of reciprocity and sufficiency of social support on the mental and physical health of 488 Japanese university students with different levels of stressors. The questionnaire included items that measured support provided for, requested by, requested of, and received from others. It also addressed negative affect associated with support relationships, as well as the levels of stressors and mental and physical health. The participants' support relationships with others were fairly reciprocal. Although being overbenefited (i.e., receiving more support than one provides) was related to stronger feelings of indebtedness, being underbenefited (i.e., providing more support than one receives) was related to stronger feelings of burden. In sum, when the participants received less support than they requested and when they provided less support than others requested, they tended to become less mentally and physically healthy. Reciprocity of support appeared to have both direct and buffering effects; however, the effects of sufficient support on health did not vary with levels of stressors.
