Dimensions of control: Mediational analyses of the stress–health relationship

Multiple dimensions of control are examined in relations with stress and physical health outcomes. Factor analysis of six measures of control from 187 elderly individuals yielded two factors: Self-Efficacy, people’s beliefs about their ability to exercise control over themselves and their environment, and Need for Power and Autonomy, the desire to control others and exercise self-determination. Various hypotheses regarding the process by which control impacts the relationship between stress and health were then tested. Self-Efficacy partially mediated and moderated the relationship between stress and physical health, whereas the Need for Power and Autonomy served neither function. Self-efficacy appears to be a lens through which older adults view stress, affecting the way it is interpreted and managed, ultimately impacting health outcomes.
