Abstract
Background
Integral components of behavioral weight-loss treatment include self-monitoring of diet and physical activity along with feedback
to participants regarding their behaviors. While providing feedback has been associated with weight loss, no studies have
examined the impact of feedback frequency on weight loss or the mediating role of self-monitoring adherence in this relationship.
to participants regarding their behaviors. While providing feedback has been associated with weight loss, no studies have
examined the impact of feedback frequency on weight loss or the mediating role of self-monitoring adherence in this relationship.
Method
Participants (N = 210) were randomly assigned to one of three self-monitoring methods with either no-daily feedback messages or daily feedback messages: (1) paper diary (PD), no-daily feedback; (2) personal digital assistant (PDA), no-daily feedback; and (3) PDA, daily tailored feedback messages (PDA + FB). The Sobel test via bootstrapping examined the direct effect of feedback frequency
on weight loss and the indirect effect through self-monitoring adherence.
on weight loss and the indirect effect through self-monitoring adherence.
Results
Receiving daily feedback messages significantly increased participants’ self-monitoring adherence. A significant effect of
feedback frequency on weight loss was noted; however, after adjusting for self-monitoring adherence, the effect of feedback
frequency on weight loss was no longer significant. Feedback frequency had a significant indirect effect on weight loss through
self-monitoring adherence.
