A Meta-Analysis Of Associations Between Weight Bias Internalization And Conceptually-Related Correlates: A Step Towards Improving Construct Validity, Kelly A. Romano, Kristin E. Heron, Cassidy M. Sandoval, Lindsay M. Howard, Rachel I. Macintyre

Psychology Faculty Publications

Weight bias internalization (WBI), a process of weight-based self-devaluation, has been associated with adverse mental and physical health. However, there are limitations with the existing conceptualization and operationalization of WBI that raise questions about the implications of this evidence-base. To address these limitations, the present study investigated the construct validity of WBI by conducting a meta-analysis of associations between WBI (as currently operationalized) and conceptually-related correlates. Studies identified through October 2021 that provided zero-order correlations for associations between WBI and conceptually-related constructs were examined. Meta-regression determined whether these associations differed across WBI measures and demographic (age, sex/gender, race, BMI) and …

Examining The Ecological Validity Of The Power Of Food Scale, Lindsay M. Howard, Kristin E. Heron, Kathryn E. Smith, Ross D. Crosby, Scott G. Engel, Stephen A. Wonderlich, Tyler B. Mason

Psychology Faculty Publications

Purpose

Appetite for palatable foods may impact eating-related behaviors in everyday life. The present study evaluated the real-world predictive validity of the Power of Food Scale (PFS) using ecological momentary assessment (EMA).

Methods

30 women who reported binge eating completed the PFS and related measures. Subsequently, during a 14-day assessment period, participants completed five daily EMA surveys of appetite and binge eating via text message and web.

Results

Results of generalized estimating equations showed that higher PFS scores were associated with higher momentary levels of hunger, eagerness to eat, and urge to eat but were unrelated to fullness, preoccupation with …

A Weight–Related Growth Mindset Increases Negative Attitudes Towards Obese People, Nic Hooper, Alison Crumpton, Michael D. Robinson, Brian P. Meier

Psychology Faculty Publications

In implicit personality theory, people with entity views or a fixed mindset perceive characteristics (e.g., intelligence) as uncontrollable, whereas people with incremental views or a growth mindset perceive characteristics as controllable. In addition to other benefits, the literature sometimes suggests that having a growth mindset will protect against prejudice, which the current two studies examine in terms of negative attitudes towards obese people. Participants (total N = 501) were randomly assigned to complete a questionnaire assessing attitudes towards an obese or non-obese person and a self-theory questionnaire also assessed ideas about body weight. People with a growth mindset, and not …

The Role Of Craving In Emotional And Uncontrolled Eating, Christina L. Verzijl, Erica Ahlich, Robert C. Schlauch, Diana Rancourt

Psychology Faculty Publications

This study presents a novel application of the cognitive processing model of alcohol craving (CPMA) from the addictions field to the role of food craving in the well-established restrained eating–overeating relationship associated with binge eating disorder (BED). A community sample (N = 1058, ages 18-66) completed an online survey assessing four core domains: restrained eating, trait food craving, uncontrolled eating, and emotional eating. In accordance with the CPMA, food craving emerged as a significant indirect effect of the association between restrained eating and both uncontrolled and emotional eating. Gender did not significantly moderate any direct or indirect associations, suggesting that …

Self-Stigma And Weight Loss: The Impact Of Fear Of Being Stigmatized, Jason Lillis, J. G. Thomas, Michael E. Levin, R. R. Wing

Psychology Faculty Publications

The current study sought to examine whether two facets of weight self-stigma (fear of enacted stigma and self-devaluation) were associated with weight change and treatment engagement for 188 individuals participating in a 3-month online weight loss program. Fear of enacted stigma predicted less weight loss 3-months later after controlling for demographics, eating problems, and psychological symptoms. Self-devaluation did not predict weight loss. Neither weight self-stigma variable predicted engagement in the online program. These results add to the literature indicating the negative effects of weight self-stigma while highlighting the central role of fear of being stigmatized by others in this process.

Delivering Acceptance And Commitment Therapy For Weight Self-Stigma Through Guided Self-Help: Results From An Open Pilot Trial, Michael E. Levin, Sarah Potts, Jack Haegar, Jason Lillis

Psychology Faculty Publications

Weight self-stigma is a promising target for innovative interventions seeking to improve outcomes among overweight/obese individuals. Preliminary research suggests acceptance and commitment therapy (ACT) may be an effective approach for reducing weight self-stigma, but a guided self-help version of this intervention may improve broad dissemination. This pilot open trial sought to evaluate the potential acceptability and efficacy of a guided self-help ACT intervention, included coaching and a self-help book, with a sample of 13 overweight/obese individuals high in weight self-stigma. Results indicated a high degree of program engagement (77% completed the intervention) and satisfaction. Participants improved on outcomes over time …

Minority Stress, Depression, Relationship Quality, And Alcohol Use: Associations With Overweight And Obesity Among Partnered Young Adult Lesbians, Tyler B. Mason, Robin J. Lewis

Psychology Faculty Publications

Purpose: Although lesbian women are more likely to be obese compared to heterosexual women, relatively little research has examined correlates of overweight and obesity among lesbians. The purpose of this study was to examine the association of minority stress and depression, relationship quality, and alcohol-use variables to overweight and obesity among lesbians in relationships.

Method: Self-identified lesbians (n = 737) in current relationships completed measures of demographics, minority stress, depressive symptoms, relationship variables, and alcohol use.

Results: Overweight and obesity were associated with more public identification as a lesbian, more depressive symptoms, increased heavy drinking, longer relationship length, and lower …

Mindful Eating: Trait And State Mindfulness Predict Healthier Eating Behavior, Christian H. Jordan, Wan Wang, Linda R. Donatoni, Brian P. Meier

Psychology Faculty Publications

Obesity and excess weight are significant societal problems. Mindfulness may encourage healthier weight and eating habits. Across four studies, we found a positive relation between mindfulness and healthier eating. Trait mindfulness was associated with less impulsive eating, reduced calorie consumption, and healthier snack choices. In addition, we found a causal effect of mindfulness on healthier eating. An experimental manipulation of state mindfulness led participants to consume fewer calories in a spontaneous eating task. We also found preliminary evidence that mindfulness affects eating behavior by encouraging attitudinal preferences for healthier foods. Taken together, these results provide strong evidence that mindfulness encourages …

Implications Of A Behavioral Weight Loss Program For Obese, Sedentary Women: A Focus On Mood Enhancement And Exercise Enjoyment, Bonnie G. Berger, Lynn A. Darby, David R. Owen, Robert Albert Carels

Psychology Faculty Publications

The benefits of a 6-month behavioral weight loss program were investigated by examining mood changes after a graded exercise test (GXT), changes in exercise enjoyment, and the relation of mood and enjoyment to program success. Obese, sedentary, postmenopausal women completed a demographic questionnaire, and physical and psychological measures. Women who completed the program (n = 25) significantly decreased their body weight and body mass index and reported significantly less tension and confusion post-GXT when measured both at the beginning and end of the program. Although their exercise enjoyment increased, their exercise-related mood changes appeared to be independent of enjoyment. Finally, …

An Examination Of The Association Of Selected Toxic Metals With Total And Central Obesity Indices: Nhanes 99-02, Miguel A. Padilla, Mai Elobeid, Douglas M. Ruden, David B. Allison

Psychology Faculty Publications

It is conceivable that toxic metals contribute to obesity by influencing various aspects of metabolism, such as by substituting for essential micronutrients and vital metals, or by inducing oxidative stress. Deficiency of the essential metal zinc decreases adiposity in humans and rodent models, whereas deficiencies of chromium, copper, iron, and magnesium increases adiposity. This study utilized the NHANES 99-02 data to explore the association between waist circumference and body mass index with the body burdens of selected toxic metals (barium, cadmium, cobalt, cesium, molybdenum, lead, antimony, thallium, and tungsten). Some of the associations were significant direct relationships (barium and thallium), …

An Obsessive-Compulsive View Of Obesity And Its Treatment, Raymond Mount, Fugen Neziroglu, Christina J. Taylor

Psychology Faculty Publications

It was hypothesized that some obese individuals who are obsessed with food and who eat compulsively may not respond to the stimulus control techniques widely used in treating obesity. Sixty-eight participants were ad- ministered a measure of obsessive tendencies and randomly assigned to three treatment modalities: (a) Exposure and response prevention; (b) Stimulus control; (c) Control. Results indicated that participants who scored high on the Eating Obsessive Compulsive questionnaire (EOC) maintained weight loss significantly better with exposure and response prevention (ERP) training than did either the stimulus control or the control group. It was concluded that for the obsessive-compulsive eater, …
