Understanding associations of control beliefs, social relations, and well-being in older adults with osteoarthritis.
Control beliefs and social relationships have been individually assessed in relation to adaptation to chronic illness, although only rarely together. Further, some control scales show psychometric limitations in older adult samples. To address these concerns, a scale assessing external control was created by factor analyzing the items from Levenson's (1974) control subscales. We tested the association of external control beliefs, measured with the new formulation of items, and two social relations variables (support and strain) to well-being measures in a sample of older adults reporting osteoarthritis (OA; N = 95, 72% female). We also compared the new formulation of items to the original subscales. The Levenson measures were significantly related to life satisfaction after controlling for social relations. However, the new externality scale was a stronger correlate than the chance subscale (though not different from powerful others). Only the new scale was related to depressive symptoms once social relations were controlled. In addition, social support was significantly associated with both outcomes.
