“…Concerns about appearance and, in the postoperative group, emerging excess skin may have contributed to physical inactivity [59]. Possible nonobesity-related barriers include low self-efficacy, negative weight bias internalization [60], or low motivation to reduce a sedentary lifestyle [59]. In the postoperative group, positive weight-related effects that can arise as early as few months after surgery [61][62][63] might have lessened the motivation to behavioral changes in some patients.…”

“…Interestingly, research produced heterogeneous results with regard to the association of internalized weight stigma and BMI: while internalized weight stigma was positively correlated with BMI in one study [1], there was no association between internalized weight stigma and BMI in other studies [2,16]. Previous studies yielded associations between internalized weight stigma and higher levels of psychopathology (e.g., depression, anxiety, eating disorder psychopathology, body image concern, lower self-esteem, and quality of life), and poorer physical and mental health in individuals with overweight and obesity in general as well as in the specific subsample of prebariatric surgery patients [2,14,15,17–23]. The explanatory power of internalized weight stigma on psychosocial aspects (e.g., depression, body image, exercise behavior) exceeded that of BMI, depression, self-esteem, own stigmatizing attitudes, and own weight stigma experiences [2,8,15,22].…”

“…More stigmatization of bariatric surgery patients relative to individuals with obesity in conservative weight loss treatment was found after standardizing for BMI and achieved weight loss, potentially because less personal responsibility for the weight loss was attributed to patients pursuing this weight loss approach [11–13]. Relatedly, internalized weight stigma was greater in the specific subsample of individuals undergoing bariatric surgery [14] compared to the population of individuals with overweight and obesity [15]. Interestingly, research produced heterogeneous results with regard to the association of internalized weight stigma and BMI: while internalized weight stigma was positively correlated with BMI in one study [1], there was no association between internalized weight stigma and BMI in other studies [2,16].…”

BackgroundInternalized weight stigma has gained growing interest due to its association with multiple health impairments in individuals with obesity. Especially high internalized weight stigma is reported by individuals undergoing bariatric surgery. For assessing this concept, two different self-report questionnaires are available, but have never been compared: the Weight Self-Stigma Questionnaire (WSSQ) and the Weight Bias Internalization Scale (WBIS). The purpose of the present study was to provide and to compare reliability, convergent validity with and predictive values for psychosocial health outcomes for the WSSQ and WBIS.MethodsThe WSSQ and the WBIS were used to assess internalized weight stigma in N = 78 prebariatric surgery patients. Further, body mass index (BMI) was assessed and body image, quality of life, self-esteem, depression, and anxiety were measured by well-established self-report questionnaires. Reliability, correlation, and regression analyses were conducted.ResultsInternal consistency of the WSSQ was acceptable, while good internal consistency was found for the WBIS. Both measures were significantly correlated with each other and body image. While only the WSSQ was correlated with overweight preoccupation, only the WBIS was correlated with appearance evaluation. Both measures were not associated with BMI. However, correlation coefficients did not differ between the WSSQ and the WBIS for all associations with validity measures. Further, both measures significantly predicted quality of life, self-esteem, depression, and anxiety, while the WBIS explained significantly more variance than the WSSQ total score for self-esteem.ConclusionsFindings indicate the WSSQ and the WBIS to be reliable and valid assessments of internalized weight stigma in prebariatric surgery patients, although the WBIS showed marginally more favorable results than the WSSQ. For both measures, longitudinal studies on stability and predictive validity are warranted, for example, for weight-related and psychosocial outcomes.

“…Findings suggest: psychological barriers to PA adoption (e.g., low motivation and self-efficacy or confidence in ability to regularly perform PA) are common (7–10) ; patients can experience pre- to postoperative improvements in PA cognitions (e.g., self-efficacy) (11) ; preoperative PA cognitions may contribute to postoperative PA changes (11) ; and intervention-related increases in physical fitness are not accompanied by improvements in exercise self-efficacy and perceived PA benefits preoperatively (12) . However, the above studies are limited by lack of: objective PA measurement, evaluation of changes in theoretically-based psychological/motivational processes in a randomized controlled trial (RCT), and examination of associations between psychological/motivational processes and bout-related MVPA.…”

Background The Bari-Active trial showed that a physical activity intervention (PAI), versus standard pre-surgical care control (SC), produced significant increases in daily bout-related moderate-to-vigorous PA (MVPA in ≥10-minutes bouts) preoperatively. The current study examined whether PAI also produces superior improvements in psychological/motivational processes that may be important for PA adoption. Objectives Compare PAI and SC on baseline to post-intervention changes in PA-related enjoyment, self-efficacy, and motivations; and examine whether greater bout-related MVPA changes are associated with greater improvements in these variables. Setting University Hospital, United States. Methods Participants [(87% female; Body Mass Index (BMI)=45.0±6.5 kg/m2] were randomly assigned to 6 weeks of PAI (n=40) or SC (n=35). PAI received weekly counseling sessions to increase daily walking exercise. At baseline and post-intervention, both groups completed 7-day objective PA monitoring and questionnaires to evaluate changes in bout-related MVPA and PA enjoyment, self-efficacy, and motivation. Results Retention was 84% at post-intervention. Intent-to-treat analyses showed that PAI on average reported more favorable changes than SC in PA enjoyment, self-efficacy, amotivation (i.e. lack of PA motivation), and identified and intrinsic regulations (i.e. more autonomous PA motivations) (p<0.01). In PAI completers (n=33), changes in bout-related MVPA and psychological/motivational variables were unrelated. Conclusion PAI produced greater improvements in PA-related enjoyment, self-efficacy, and motivations, than SC. The lack of association between objectively-measured PA changes and psychological/motivational processes highlights the need for future research to identify which processes are most important for PA adoption and maintenance, and to determine whether the method used to measure PA affects the pattern of association.
