Stability in a measure of children's health locus of control.

Increased interest in children's health locus of control has precipitated continued examination of the psychometric properties of scales measuring this concept. The Children's Health Locus of Control scale (CHLC) was administered to more than 1,000 urban black students in each of four years across three grade levels: Year 1 - grades four-six to Year 4 - grades seven-nine. Factor analyses revealed five factors forming scales with acceptable reliability at each year. Students' beliefs that they have control over their own health increased as a function of age. Beliefs in self-control had low, negative correlations with measures of external control. Stability of CHLC and the relatively simple procedure (16 dichotomous items) suggest that, despite problems with wording of some items, CHLC is an appropriate and efficient measure for comparing cross-sectional and longitudinal samples in this age range.
