Abstract

BACKGROUND:

Despite evidence that daily self-weighing is an effective strategy for weight control, concerns remain regarding the potential for negative psychological consequences.

PURPOSE:

The goal of the study was to examine the impact of a daily self-weighing weight-loss intervention on relevant psychological constructs.

DESIGN:

A 6-month RCT.

SETTING/PARTICIPANTS:

The study sample (N=91) included overweight men and women in the Chapel Hill NC area.

INTERVENTION:

Between February and August 2011, participants were randomly assigned to a daily self-weighing intervention or delayed-intervention control group. The 6-month intervention included daily self-weighing for self-regulation of diet and exercise behaviors using an e-scale that transmitted weights to a study website. Weekly e-mailed lessons and tailored feedback on daily self-weighing adherence and weight-loss progress were provided.

MAIN OUTCOME MEASURES:

Self-weighing frequency was measured throughout the study using e-scales. Weight was measured in-clinic at baseline, 3 months, and 6 months. Psychological outcomes were assessed via self-report at the same time points.

RESULTS:

In 2012, using linear mixed models and generalized estimating equation models, there were no significant differences between groups in depressive symptoms, anorectic cognitions, disinhibition, susceptibility to hunger, and binge eating. At 6 months, there was a significant group X time interaction for body dissatisfaction (p=0.007) and dietary restraint (p<0.001), with the intervention group reporting lower body dissatisfaction and greater dietary restraint compared to controls.

CONCLUSIONS:

Results indicate that a weight-loss intervention that focuses on daily self-weighing does not cause adverse psychological outcomes. This suggests that daily self-weighing is an effective and safe weight-control strategy among overweight adults attempting to lose weight.

TRIAL REGISTRATION:

This study is registered at clinicaltrials.gov NCT01369004.
