Show moreWeight management success is contingent upon treatment utilization and engagement. Unfortunately, low enrollment, poor attendance, and high attrition from weight management programs are major barriers for long-term weight loss. This study aimed to applying the psychological flexibility model to the problem of weight management engagement. The current study evaluated the hypotheses that lower experiential avoidance, the process of changing, suppressing, or avoiding unpleasant experiences in an effort to regulate behavior, and higher values congruence, behaving consistently with one’s values, predict treatment engagement and successful weight loss. Participants were 183 overweight and obese veterans (91.3% Male, 77.6% African American). Participants completed a demographics questionnaire, the Acceptance and Action Questionnaire for Weight-Related Problems (AAQ-W) and the Valued Living Questionnaire (VLQ). Analyses revealed that experiential avoidance significantly predicted probability of enrolling (OR=1.03, p<.01). Experiential avoidance and values congruence were not significantly related to attendance, and experiential avoidance approached significance for dropout (OR=6.54, p=.08). AAQ-W was related to baseline BMI (β=7.49, p<.001) and 3-month BMI trajectory (β= 0.54, p<.01) for enrollees, while experiential avoidance predicted 3-month weight change for nonenrollees (β =0.28, p<.05). The extant research on weight management suggests that much can be done to improve treatment outcomes. Increasing engagement is a major component of improving weight management success. The findings from this study suggest that targeting psychological flexibility can be a means to achieving this goal. Future weight management research should continue to explore this relationship.

Show moreThe purpose of this study was to gain a better understanding of the roles of gender, body mass index (BMI), and rumination in the relation of negative affect (NA) and emotional eating (EE). The following associations were proposed: (1) NA is positively associated with EE, (2) rumination both moderates and (3) mediates the association between NA and EE, (4) gender moderates the association between NA and emotional eating, and (5) EE mediates the association between NA and BMI. Participants consisted of average, overweight, and obese, males (n = 140) and females (n = 152) from both community and university settings. Participants completed self-report questionnaires, including the Binge Eating Questionnaire, Positive and Negative Affect Scale, Dutch Eating Behavior Questionnaire, and Ruminative Response Questionnaire. Results agreed with previous findings that NA positively correlated NA was positively associated with EE. Results indicated that rumination moderated the association between NA and EE; however rather than greater rumination strengthening this association, it led to a weaker association between NA and EE. Rumination mediated the association between NA and EE, and EE mediated the association between NA and BMI. Lastly, gender did not moderate the association between NA and EE. Results indicate the importance of rumination in those with a tendency to emotionally eat. They also point to the impact of EE on BMI, and suggest further studies should examine whether an association exists between EE and weight gain. In addition, results indicate similarities between men and women in regard to emotionally eating in response to NA.
