For 21 days, 123 participants provided measures of their daily depressogenic adjustment, including Beck's cognitive triad, causal uncertainty, control over the environment, self-esteem, and anxiety, and they described the positive and negative events that occurred. Daily adjustment negatively covaried with the number of negative events occurring each day and, except as measured by anxiety, positively covaried with positive events. The covariance between negative events and adjustment was stronger than the covariance between positive events and adjustment. Participants also provided measures of depressive symptoms. For the self-esteem and cognitive triad measures, adjustment covaried more strongly with negative and positive events for the depressed than they did for the nondepressed.

This research suggests that daily psychological adjustment covaries with daily events and that trait levels of adjustment moderate this covariation. Although informative, this research is limited in important ways. First, research on daily events and adjustment has operationalized daily adjustment primarily in terms of mood. Second, studies examining how day-level relationships are moderated by trait-level measures have focused on the moderating role of neuroticism and related constructs; few studies have focused on depression.The focus of existing research may limit its utility for understanding more specific phenomena such as selfesteem and depression. Although understanding disturbances in mood is clearly important to understanding both self-esteem and depression, considerable research suggests that state-level constructs other than mood are worth investigating. For example, research indicates that depression is associated with greater lability in selfesteem and that depression may moderate day-level relationships between events and self-esteem (Butler, Hokanson, & Flynn, 1994).Accordingly, the present study examined day-level relationships between events and state measures of depressogenic adjustment other than mood and how such relationships varied as a function of trait depressogenic adjustment. Each day for 3 weeks, participants described the positive and negative events that occurred and provided measures of state adjustment. Over a 4 1/2-month period, participants also provided four reports of their depressive symptoms, which collectively were used to measure depression.Three hypotheses guided the study: (a) daily adjustment would covary negatively with daily negative events and positively with positive events, (b) adjustment would covary more strongly with negative events than with positive events, and (c) the covariation between daily events and adjustment would be stronger for people who were 1692
