The hypothesis that identity commitment affects the experience of identity-
related stressors brings identity theory and social stress research togethe
r. Research findings are not yet conclusive regarding this hypothesis. Part
of the contradictory research findings stem from inadequate knowledge abou
t the causal direction of the relationship between depression and commitmen
t. The authors analyze if identity commitment interacts with social stress
in its impact on mental well-being. Only chronic stress has a moderate impa
ct on the experience of depression. Commitment toward the gay identity did
not buffer the experience of stress. The authors also use a nonrecursive mo
del to establish the causal relationship between depression and commitment.
They show that it is depression that lowers identity commitment. It is con
cluded that identity commitment cannot act as a buffer against identity-rel
ated stress because commitment is affected by the resulting distress.
