Coping, self-efficacy and psychiatric history in patients with both chronic widespread pain and chronic fatigue.
OBJECTIVE
To investigate the relationship of coping style and self-efficacy to functional impairment in a group of patients with both chronic widespread pain (CWP) and chronic fatigue, as well as the possible mediating role of psychiatric diagnosis.


METHODS
We identified 138 consecutive clinic patients who met criteria for CWP and chronic fatigue. We collected demographic and clinical characteristics, as well as measures of emotion-focused and problem-focused coping styles, fatigue-related self-efficacy and self-reported general health. Psychiatric diagnoses were determined with a structured interview. Short Form-36 subscales of pain-related and fatigue-related functioning were the dependent variables in ordinal multiple regression analyses to identify the best-fit model for each.


RESULTS
In the final model for pain, increased functional impairment was associated with increased emotion-focused coping as well as less education, lower general health scores and higher body mass index. Conversely, in the final model for fatigue, increased functional impairment was significantly associated with less emotion-focused coping, lower general health scores and lower self-efficacy.


CONCLUSIONS
The unexpected finding that emotion-focused coping was associated differently with chronic pain and fatigue among patients who experience both symptoms is discussed in the context of the research on the effects of self-efficacy and possible treatment approaches.
