Although social support has been studied extensively in terms of its role i
n the relationship between stress and health, less attention has been devot
ed to the impact of negative social interactions. In this investigation, th
e authors examined the unique contributions of positive social support and
negative social exchange in the relationship between stress and health symp
toms, using data from 206 undergraduates at a large state university. Negat
ive social exchange accounted for more variance in physical health symptoms
than did life-event stress, daily hassles, or social support. Me relations
hip between negative social interaction and physical symptoms was not the r
esult of variance shared with psychological well-being. The importance of a
ttending to negative aspects of social interaction among university student
s in terms of their health and well-being is discussed.
