Abstract
Background Internalized weight stigma (IWS) is highly prevalent and associated with deleterious mental and physical health outcomes. Initiatives are needed to address IWS and promote effective coping and resilience among individuals who are exposed to weight stigma. We conducted a systematic review of psychological interventions for IWS and examined their feasibility, acceptability, and preliminary efficacy at reducing IWS and related negative physiological and psychological health outcomes. Methods Eight databases were searched. Inclusion criteria included: (1) psychological intervention; (2) published in English; and (3) included internalized weight stigma as an outcome. Exclusion criteria included: (1) commentary or review; and (2) not a psychological intervention. A systematic narrative review framework was used to synthesize results. Results Of 161 articles screened, 20 were included. Included interventions demonstrated high feasibility, acceptability, and engagement overall. Sixteen of 20 included studies observed significant reductions in IWS that were maintained over follow-up periods, yet data on whether interventions produced greater reductions than control conditions were mixed. Studies observed significant improvements in numerous physical and mental health outcomes. Conclusions Findings indicate that existing interventions are feasible, acceptable, and may provide meaningful improvements in IWS and associated health outcomes, highlighting the potential for psychological interventions to promote improved health and wellbeing in individuals with IWS. Additional research using rigorous study designs (e.g., randomized controlled trials) is needed to further evaluate the efficacy of interventions for IWS.

Abstract
Harmful effects of weight self-stigma on quality of life and health behaviors have been well-established. However, the processes that lead to these negative outcomes are less understood. Psychological inflexibility is defined as a pattern of rigid psychological reactions dominating over values and meaningful actions. A lack in valued action is characterized by the absence of activities that are connected to what is personally meaningful. In this secondary analysis, we aim to extend research by examining two subprocesses of psychological inflexibility, experiential avoidance and lack of valued action, as statistical mediators of the relations between weight self-stigma and quality of life/health behavior outcomes. Baseline data from a clinical trial comparing weight loss maintenance interventions in a sample of 194 adults living with overweight or obesity and seeking treatment is analyzed. Results show that greater experiential avoidance and lower valued action were significantly related to lower quality of life and satisfaction with social roles, as well as greater depression, anxiety, and binge eating. Further, results from a parallel mediation analysis indicated that weight self-stigma is indirectly related to anxiety, disinhibited eating, and hunger through the relationship with experiential avoidance and lack of valued action.

Efficacy of a Digital Acceptance and Commitment Therapy Intervention for the Improvement of Self-management Behaviors and Psychological Flexibility in Adults With Cardiac Disease: Protocol for a Single Case Experimental Design. JMIR Res Protoc 2022; 11:e33783. [PMID: 35363156 PMCID: PMC9015764 DOI: 10.2196/33783] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2021] [Revised: 12/17/2021] [Accepted: 12/18/2021] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Research indicates that the management of distress levels in those with cardiac disease is not only important for improving quality of life and functioning but also critical for condition management; adherence to treatment; and, ultimately, disease prognosis and progression. Acceptance and commitment therapy (ACT) has consistently demonstrated positive long-term outcomes across a wide array of conditions, including chronic illness. However, most empirical investigations conducted to date have also involved in-person therapy, which can be difficult to access, particularly for those dealing with the demands of chronic disease. OBJECTIVE The objective of our research is to evaluate a digital ACT intervention for improving self-management behaviors and distress levels in those with cardiac conditions. METHODS The digital ACT intervention will be delivered via a digital health self-management platform over 6 sessions. This will involve a randomized, multiple baseline, single case experimental design with approximately 3 to 15 adults with cardiac disease. The independent variable for each participant will be the pre-post intervention phase. The dependent variables will be a daily self-report measure of psychological flexibility as well as objective measures of condition self-management (eg, blood pressure readings) and engagement with the app (eg, completing guided mindfulness). One-to-one qualitative interviews will also be conducted to further examine participants' experiences with using the intervention and what factors contribute to or impede successful outcomes. RESULTS Participant recruitment and data collection began in October 2021, and it is projected that the study findings will be available for dissemination by spring 2022. CONCLUSIONS The findings will be discussed in terms of how a digital ACT intervention can best meet the needs of cardiac patients.

Abstract
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 study-level (publication status, sample type, study quality) moderators. Data for 128 (sub)samples were identified (Msample size = 477.83, SD = 1679.90; Mage = 34.46, SD = 12.17; range = 10.21-56.60). Greater WBI exhibited large to very large associations with factors suggested to have considerable overlap with this construct (negative and positive body image, self-devaluation), general and weight-specific experiential avoidance, and individuals' anticipation of future weight stigma. Associations varied for other constructs that have been differentially included in conceptualizations of WBI (endorsing weight bias, weight stigma stereotype awareness, weight stigma experiences), and via measurement-related, demographic, and study-level factors. These findings provide important information that can advance WBI conceptualization and measure-refinement.

Abstract
PURPOSE OF REVIEW This review explores potential sources of weight bias and stigma during the COVID-19 pandemic, including "quarantine-15" messages and discussion of obesity in media and public health campaigns. We examine evidence of the effects of weight bias on well-being during the pandemic and highlight unanswered questions to be addressed in future research. RECENT FINDINGS Studies that have investigated weight change during stay-at-home orders have yielded mixed findings and relied predominantly on self-reported retrospective recall, thus providing weak evidence of a widespread "quarantine-15" effect. No studies to date have evaluated the effects on weight stigma and health of obesity-focused COVID-19 media and public health messages. Individuals with a history of experiencing weight bias may be more vulnerable to binge eating and psychological distress during the pandemic. Weight bias and stigma during the COVID-19 pandemic, and their effects on health and well-being, warrant greater investigation and consideration in public health efforts.

Abstract
Objective: The purpose of the present study was to examine the validity and reliability of the Persian version of the Weight Control Strategies Scale among individuals engaged in weight loss or weight maintenance. Method: This descriptive study conducted from October 2019 to February 2020 on social media networks. A total of 420 men and women were selected using consecutive sampling. They completed the Persian version of the Weight Control Strategies Scale and the Self-Compassion Scale. Data were analyzed using descriptive statistics, Cronbach’s α, confirmatory factor analysis, and Pearson product-moment correlations. Results: Internal consistency for the total score of the Persian version of Weight Control Strategies Scale was excellent and acceptable to good for all 4 subscales (in all cases over α = 0.70). Confirmatory factor analysis supported the factor structure of the original model of the scale, but, it was different from the model at the item level. Moreover, the Persian version of Weight Control Strategies Scale had good convergent validity. Conclusion: Psychometrically speaking, the Persian version of the Weight Control Strategies Scale is a valid and reliable tool to assess the psychological and behavioral profile of individuals engaging in losing or maintaining weight, both for clinical and research purposes.

Abstract
Weight bias internalization (WBI) is an understudied form of internalized stigma, particularly among treatment-seeking adults with overweight/obesity. The current study surveyed 13,996 adults currently engaged in weight management in the first multinational study of WBI. From May to July 2020, participants in six Western countries completed the Modified Weight Bias Internalization Scale (WBIS-M) and measures of weight change, health behaviors, psychosocial well-being, and health-related quality of life (HRQOL). Participants were majority white, female, middle-aged, and categorized as having overweight or obesity based on body mass index. Results showed higher mean WBIS-M scores among participants in the UK, Australia, and France than in Germany, the US, and Canada. Across all countries, and controlling for participant characteristics and experiences of weight stigma, WBIS-M scores were associated with greater weight gain in the past year. Participants with higher WBIS-M scores also reported poorer mental and physical HRQOL, less eating and physical activity self-efficacy, greater engagement in eating as a coping strategy, more avoidance of going to the gym, poorer body image, and greater perceived stress. Few interaction effects were found between experiences and internalization of weight stigma. Overall, the current findings support WBI as a robust correlate of adverse weight-related health indices across six Western countries. Prospective and experimental studies are needed to determine directionality and causality in the relationship between WBI and poor health outcomes.

Abstract
BACKGROUND Overweight and obesity are public concerns with risk of adverse health outcomes. Health-related quality of life (HRQoL) is lower in adolescents than children in general. An increase in body mass index (BMI) is associated with a decrease in HRQoL. The purpose of this study was to measure and explore the HRQoL among adolescents with overweight or obesity who had participated in an intervention study, Young & Active, with the aim of increasing physical activity (PA), reducing BMI and promoting HRQoL. METHODS Mixed methods, with a convergent design, were used to investigate how different methodological approaches could expand our understanding of the adolescents' HRQoL. Quantitative post-intervention data on HRQoL were collected among the 84 intervention participants, aged 13-14 years, using the KIDSCREEN 52 questionnaire. The data were compared with a Norwegian reference population of 244 individuals, and analysed using a non-parametric Mann-Whitney test. Qualitative semi-structured interviews were conducted with 21 adolescents from the intervention. A directed approach to content analysis was adopted, using the ten sub-scales from KIDSCREEN 52. RESULTS HRQoL in the intervention sample was significantly reduced on the sub-scale of physical well-being compared to the reference population. The reference population scored significantly lower than the intervention sample on the sub-scale of parent relation and home life. No significant differences were found on the other sub-scales. The qualitative data supported the quantitative findings on the sub-scale of physical well-being, but showed that perceptions of fitness, energy level or health could vary. Regarding parent relations, the interviewees extended this to include relationships to other family members as equally important. Most of the interviewees expressed a negative view of their bodies, but not their clothing or accessories. This may explain why no statistically significant differences were found on these aspects in the results from the KIDSCREEN questionnaire. CONCLUSION The use of the KIDSCREEN 52 instrument gave important indications about the adolescents' HRQoL and need for additional follow up. The qualitative data provided an in-depth understanding that nuanced the findings and widened our knowledge of the adolescents HRQoL. Combining methods enabled a comprehensive approach to research on HRQoL.

Abstract
OBJECTIVE To test the effects of a cognitive-behavioral intervention for weight bias internalization (WBI; i.e., self-stigma) combined with behavioral weight loss (BWL). METHOD Adults with obesity and elevated WBI were randomly assigned to BWL alone or combined with the Weight Bias Internalization and Stigma Program (BWL + BIAS). Participants attended weekly group meetings for 12 weeks, followed by 2 biweekly and 2 monthly meetings (26 weeks total). Changes at Week 12 on the Weight Bias Internalization Scale (WBIS) and Weight Self-Stigma Questionnaire (WSSQ) were the principal outcomes, with changes at Week 26 assessed as secondary outcomes. Other outcomes included changes in mood, body image, eating behaviors, self-monitoring, and weight. RESULTS Seventy-two participants were randomized (84.7% female, 66.7% Black, mean age = 47.1 ± 11.5 years) Linear mixed models showed no significant differences between the BWL + BIAS and BWL groups in WBIS changes at Week 12 (-1.3 ± 0.2 vs. -1.0 ± 0.2) or week 26 (-1.5 ± 0.2 vs. -1.3 ± 0.2). BWL + BIAS participants had greater reductions in WSSQ total scores at Week 12 (p = .03), with greater changes on the self-devaluation subscale at Weeks 12 and 26 (p ≤ .03). BWL + BIAS participants reported significantly greater benefits on measures of eating and self-monitoring. Percent weight loss at Week 26 did not differ significantly between groups (BWL + BIAS = -4.5 ± 1.0%, BWL = -5.9 ± 1.0%, p = .28). CONCLUSION A psychological intervention for WBI produced short-term reductions in some aspects of weight self-stigma in persons with obesity.
