The effects of impulsivity, self-efficacy, and depression on body mass index
There are a number of factors that have been found to be effective in weight loss but little is known about factors influencing weight loss maintenance. This study examined the effects of impulsivity, weight self-efficacy, and depression on weight regain in previously obese participants. This study tested 4 hypotheses using a retrospective quasi-experimental design with 281 participants. People were assigned to groups based on whether they had lost at least 10% of their body weight and maintained it (n=123) or lost at least 10% of their body weight and gained weight back within the past 3 years (n=158).
In an examination of the effects of impulsivity, weight self-efficacy, and depression on weight regain, only 1 componenet of impulsivity was statistically significant. For each unit increase in the nonplanning impulsiveness score, the odds ratio indicated a propensity for weight regain rather than weight maintenance. Maintenance of weight loss was found to be independent of gender and marital status, but dependent on age, and education level. The results of the study were compared to previous research and discussed in terms of clinical implications, limitations, and implications for future research.
