Numerous psychosocial and health factors contribute to perceived stress, social support, and problem-solving coping relating to overall well-being and life satisfaction in older adults. The effect of social support and problem-solving coping, however, remains largely untested as potential moderators. The present study was conducted to test whether social support and problem- solving coping would moderate the relation between perceived stress and life satisfaction in older adults. First, I anticipated that stress will be negatively related to life satisfaction at low levels of social support, while at high social support; stress will be unrelated to life satisfaction. Second, I expected that with low problem- solving coping, stress will be negatively related to life satisfaction, whereas, at levels of high problem- solving coping, stress will be unrelated to life satisfaction. Using an experimental survey and interview design with hierarchical regression analyses, I found no support that social support would moderate the relation between stress and life satisfaction. I found support that problem-solving coping moderated the relation between stress and life satisfaction. For individuals who engage in higher levels of problem- solving coping, higher levels of stress predicted lower levels of life satisfaction. On the other hand, at lower levels of problem-solving coping, more stress predicted lower levels of life satisfaction.
