Introduction:
Our recent work demonstrated that obese/overweight individuals exhibit different patterns of self-weighing behavior over time. To identify possible contributors to varying patterns, we examined the differences in changes in self-efficacy (SE) by self-weighing pattern groups.
Hypothesis:
Higher self-weighing group would have greater increases in SE levels.
Methods:
This was an analysis of data from a 12-mo behavioral weight-loss intervention study. Each participant was given a Wi-Fi-enabled scale to transmit weight data to a server. Three self-weighing patterns were determined by group-based trajectory modeling:
high/consistent
(>6 days/week);
moderate/declined
(declined from 4-5 to 2 days/week);
minimal/declined
(5-6 to 0 days/week). SE was assessed semiannually by the Weight Efficacy Lifestyle (WEL) Scale, yielding ratings of one’s confidence to avoid eating under varied conditions (e.g., home, social settings) and moods (e.g., depressed, stressed). Higher scores indicate greater levels of SE. Linear mixed modeling was used for data analysis.
Results:
The sample (N=148) was 90.5% female, 81.1% White, with mean (SD) age of 51.3 (10.1) years and BMI of 34.1 (4.6) kg/m
2
. There were no significant differences in self-weighing groups for WEL total and subscale scores at baseline. There was significant group effect for changes in subscale score of Negative Emotions, group by time effect for Social Pressure and time effect for Positive Activities. The
high/consistent
self-weighing group showed significant increases in each subscale score and total score from 0 mos to 6 or 12 mos, with the subscale score of Social Pressure having a marginally significant increase at 12 mos, while the other two groups had no changes over time (see table).
Conclusions:
Participants in the
high/consistent
self-weighing group reported increased SE over time for eating in different contexts. Future work needs to explore strategies to improve eating self-efficacy and self-weighing for those unable to establish this habit. |
