Social control in older adults' diabetes self management and well-being.

The "dual effects" hypothesis argues that social control can be effective in promoting positive health-related behavior change, but it can also jeopardize the targeted individual's well-being. This hypothesis is tested using hemoglobin A1C as an objective indicator of behavioral compliance with diabetes self-management behavior and depressive symptoms. Differences in the effects of social control on A1C and depressive symptoms by sex and ethnicity are tested. Cross-sectional data were obtained from a multi-ethnic sample of older adults with diabetes (N = 593). Greater social control was associated with poorer rather than better odds of achieving glucose control, and with greater depressive symptoms. There was no evidence that social control has differential effects on either glucose control or depressive symptoms by sex or ethnicity. Active use of social control attempts by family members and friends, especially if they are coercive or punitive in nature, are likely counterproductive for maintaining the physical and mental health of older adults with diabetes.
