Coping with daily events and short-term mood changes: an unexpected failure to observe effects of coping.

This study examined the relationship between coping efforts and stress-related mood changes. Men and women with high levels of work or marital stress reported stress and coping efforts approximately once an hour for 2 days using an electronic diary. Stress episodes were identified as a stress-free time followed by a stressor at the next time point. Analyses examined how appraisals and coping influenced pre- to poststress mood change and how problem appraisals were related to coping efforts. Greater mood changes were associated with appraisals of high stress and high disruptiveness. Appraisals of high control and high desirability were associated with more planning, direct action, and fewer acceptance coping efforts. Coping failed to predict any pre- to poststressor mood changes. Possible explanations for the overall failure of coping to predict momentary mood changes are discussed.
