| dc.description.abstract | Forty-eight overweight females were randomly assigned into
four groups: 1) stimulus control, 2) exercise, 3)
stimulus control plus exercise, and 4) counting calories
(control), to determine which treatment was most
effective for weight and fat loss.
Locus of Control was assessed with Rotter's I-E and
Saltzer's Weight Locus of Control scales. Weekly measures
of food intake and energy expenditure were taken. The
relation of program adherence to weight loss was also
assessed.
Analyses of covariance showed that there was a
significant effect of stimulus control procedures on weight
and fat, whereas there was no effect of exercise. The
weight loss was maintained six months after the end of
the program in the groups that had received stimulus
control treatment. Analyses of variance indicated that
food intake decreased in the stimulus control group,
whereas there was no significant effect of exercise on
energy expenditure. Locus of Control orientation did not
correlate with amount of weight loss. Program adherence
did not correlate with amount of weight loss. | |
