Differences in locus of control between obese adult and adolescent females undergoing weight reduction.

Rotter's (1966) Internal-External (I-E) Scale was administered to 65 adult and adolescent females in two outpatient obesity treatment programs. The adults were significantly higher in internal locus of control (LOC) and the adolescents higher in external LOC. These differences suggest that although the adults felt limited control over their weight and eating behavior, this did not reflect a lack of perceived control over other factors in their lives. In contrast, the adolescents appeared to feel that they had limited control over an array of factors in their lives.
