Sense of control: potentials for intervention.

A substantial amount of research has demonstrated that the sense of control is associated with numerous positive outcomes, including good health. Many aspects of the personal and social conditions of old age influence the control-health relationship. Environmental events associated with old age often place limits on the range of outcomes that are attainable by older people. Moreover, the association between control and indicators of health status may be altered by old age. Finally, old age may influence the relationship between control and various health maintenance behaviors. Aspects of the sense of control can be altered with small interventions that can enhance health specifically and the quality of aging in general. Given the relationship between control and health in old age, several possible factors may help explain or mediate this relationship including mechanisms of behavioral and cognitive change, and physiological adaptations. Despite the largely positive outcomes associated with increased sense of control, negative outcomes are also possible, especially when control is not desired or entails too much responsibility or other demands.
