Coping effectiveness: determinants and relevance to the mental health and affect of family caregivers of persons with dementia

Family caregivers of persons with dementia (n = 141) rated their effectiveness in coping with a challenging symptom displayed by their relative, and completed measures of their ways of coping, their general (optimism) and specific (caregiving self-efficacy) outcome expectancies, their affect (positive and negative), and the mental health subscale of the SF-36. Hierarchical regression analyses revealed that coping effectiveness is more highly influenced by relatively stable outcome expectancies than by the ways of coping that are employed. In addition, optimism exerted a consistent and relatively strong impact on affect and mental health, overshadowing the influence of coping and judgments of its effectiveness. However, coping effectiveness not only had a significant main effect on the caregivers' mental health and negative affect, but also served a stress buffering function by reducing negative affect.
