The Role of Internal Health Locus of Control in Relation to Self-Rated Health in Older Adults.

The present study examined how internal health locus of control is associated with older adults' self-rated health. Multivariate analyses with older participants (aged ≥ 60) in the MIDUS II (n = 1,533) showed that internal health locus of control was not only directly associated with positive ratings of health but also interacted with gender and race. The positive impact of internal health locus of control on self-rated health was particularly greater in females and Whites than their counterparts. Findings highlight the important role of internal health locus of control in the psychological mechanism of health and call attention to group-specific strategies for health promotion.
