Global perceived stress level as a moderator of the relationship between negative life events and depression.
The present research investigated the proposal that global perceived stress level moderates the degree of relationship between negative life events and depression. Accordingly, subjects in this study completed the Beck Depression Inventory (BDI), the Life Experiences Survey (LES), and the Perceived Stress Scale (PSS). The PSS provides a measure of global perceived stress level, or the general tendency to view one's life as being unpredictable, out of control, and overwhelming. Consistent with past research, the findings revealed an increase in depression level as negative life change scores increased. Of special importance, however, was the finding that global level of stress significantly moderated the relationship between depression and negative life events. For those low on perceived stress, negative life changes had only a minimal impact on depression level. In contrast, for those high on perceived stress, the relationship was more pronounced. These findings were then discussed with regard to the possible role of cognitive appraisals in enhancing the symptoms of psychopathology experienced by individuals high on global level of perceived stress.
