Who's a good boy? Effects of dog and owner body weight on veterinarian perceptions and treatment recommendations.

BACKGROUND: Weight bias against persons with obesity impairs health care delivery and utilization and contributes to poorer health outcomes. Despite rising rates of pet obesity (including among dogs), the potential for weight bias in veterinary settings has not been examined. SUBJECTS/METHODS: In two online, 2 × 2 experimental studies, the effects of dog and owner body weight on perceptions and treatment recommendations were investigated in 205 practicing veterinarians (Study 1) and 103 veterinary students (Study 2). In both studies, participants were randomly assigned to view one of four vignettes of a dog and owners with varying weight statuses (lean vs. obesity). Dependent measures included emotion/liking ratings toward the dog and owners; perceived causes of the dog's weight; and treatment recommendations and compliance expectations. Other clinical practices, such as terms to describe excess weight in dogs, were also assessed. RESULTS: Veterinarians and students both reported feeling more blame, frustration, and disgust toward dogs with obesity and their owners than toward lean dogs and their owners (p values < 0.001). Interactions between dog and owner body weight emerged for perceived causes of obesity, such that owners with obesity were perceived as causing the dog with obesity's weight, while lean owners were perceived as causing the lean dog's weight. Participants were pessimistic about treatment compliance from owners of the dog with obesity, and weight loss treatment was recommended for the dog with obesity when presenting with a medical condition ambiguous in its relationship to weight. Veterinarians and students also reported use of stigmatizing terms to describe excess weight in dogs. CONCLUSIONS: Findings from this investigation, with replication, have implications for training and practice guidelines in veterinary medicine.

Development of a cognitive-behavioral intervention for internalized weight stigma.

Individuals with a higher body weight are the targets of pervasive social stigma. This stigma can become self-directed or internalized, leading to self-devaluation due to weight. Internalized weight stigma is associated with adverse outcomes for mental and physical health, yet little is known about how to prevent or diminish this internalization. This article introduces a novel, group-based, psychological intervention designed to reduce internalized weight stigma and its ill effects on health. Rationale is provided for the therapeutic approach and for the intervention's proposed utility in behavioral weight management settings. Intervention content is described in detail, along with preliminary evidence of its potential effects on psychological and behavioral outcomes.

Prevalence of diagnosed psychiatric disorders among adults who have experienced and internalized weight stigma.

Objective: Experiences and internalization of weight stigma are associated with greater self-reported psychological distress and symptoms of psychiatric disorders such as depression and anxiety. However, little is known about the extent to which individuals who have experienced and internalized weight stigma are diagnosed with or provided treatment for psychiatric conditions. The current study aimed to characterize the prevalence of diagnosed psychiatric disorders among adults with obesity who had experienced and internalized weight stigma. Methods: Weight-loss treatment-seeking adults with a history of experiencing weight stigma and high levels of internalized weight stigma were recruited for two clinical trials. Results: In Study 1 (n = 84, 83.3% women, 67.9% Black), 25% of participants reported a lifetime history of a mood disorder. Few participants (<10%) reported current psychiatric diagnoses or use of psychiatric medications. In Study 2 (n = 129, 88.4% women, 65.1% white), one-third of participants reported a mood disorder history, and 21.7% reported an anxiety disorder history, with approximately 16%-18% reporting current diagnoses. In both studies, few participants reported a history of a diagnosed eating disorder despite high rates of current full- or subthreshold symptoms. Based on Beck Depression Inventory-II scores, approximately 54%-64% of participants reported mild or greater symptoms of depression. Conclusions: Overall, lifetime history of diagnosed psychiatric disorders and current symptoms of depression and eating disorders were relatively high across two samples. More research is needed to determine the impact of weight stigma on the diagnosis and treatment of eating disorders and other psychiatric concerns.

Refining the conceptualization and assessment of internalized weight stigma: A mixed methods approach.

Internalized weight stigma has gained increasing attention in empirical studies, though questions remain about the adequacy of existing measures. The current study utilized a mixed methods approach, including a novel semi-structured interview, to revisit the conceptualization of internalized weight stigma and explore in more depth the stereotypes and impacts of weight reported by individuals with high scores on the widely-used Weight Bias Internalization Scale. All participants were interviewed as part of the screening procedures for two clinical trials (Study 1 n = 84, mean age=47.8 years, 83.3% women, 67.9% Black, mean BMI=39.2 kg/m2; Study 2 n = 129, mean age=50.0 years, 88.4% women, 65.1% white, mean BMI=37.8 kg/m2). The most common weight stereotypes identified were being lazy, lacking willpower or self-control, and having poor eating habits. Up to 66% of participants reported that they did not endorse negative weight stereotypes or apply them to themselves. The most highly identified impacts of weight were on self-image (>70%) and emotions (68-83%), followed by social (37-62%) and health concerns (20-25%). Approximately 60% of participants indicated that weight affected their self-directed thoughts and feelings "very much" to "extremely." Findings have implications for understanding and assessing internalized weight stigma in research and in clinical settings where interventions are needed.

Long-term effects of an internalized weight stigma intervention: A randomized controlled trial.

OBJECTIVE: To test the long-term effects of a group-based, psychological intervention designed to reduce internalized weight stigma (IWS, i.e., self-stigma), delivered in combination with behavioral weight loss (BWL) treatment, compared to BWL alone. METHOD: Adults with obesity who had experienced and IWS (N = 105, Mage = 49 years, 90.5% women, 70.5% White, 24.8% Black, MBMI = 38 kg/m²) were randomized to receive BWL with the Weight Bias Internalization and Stigma (BIAS) Program or BWL alone. Participants received weekly group treatment for 20 weeks, followed by 52 weeks of monthly and every-other-month sessions. Percent weight change at Week 72 was the primary outcome, with secondary outcomes of weight change at other time points; physical activity (measured by accelerometry, interview, and self-report); cardiometabolic risk factors; and psychological and behavioral outcomes. Intention-to-treat analyses used linear mixed models to test for between-group differences. Treatment acceptability was assessed. RESULTS: Participants in the BWL + BIAS versus BWL group lost 2 percentage points more of baseline weight at Week 72, which was not a significant difference (mean weight change = -7.2% vs. -5.2%, 95% CI [-4.6 to 0.6], p = 0.14, d = 0.18). The BWL + BIAS (vs. BWL) group produced significantly greater improvements in weight self-stigma, eating self-efficacy, and some aspects of quality of life at specific time points. Most outcomes improved significantly over time but did not differ between groups. The trial had high retention and treatment acceptability, with higher ratings in the BWL + BIAS versus BWL group. CONCLUSIONS: No significant differences in weight loss were observed between the BWL + BIAS versus BWL group. Possible benefits of addressing weight stigma in weight management warrant further investigation. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Adverse Childhood Experiences and Weight Stigma: Co-Occurrence and Associations with Psychological Well-Being.

Prior research has demonstrated that individuals with a higher body weight (i.e., obesity) have a relatively high incidence of adverse childhood experiences (ACEs) (e.g., abuse, neglect). Individuals with obesity are also susceptible to experiencing and internalizing weight stigma. Negative physical and mental health consequences have been associated with both ACEs and weight stigma, yet the interplay between these factors has not been explored. The current study examined ACEs in a sample of 105 treatment-seeking adults with obesity who all reported having experienced and internalized weight stigma (90.5% women, 70.5% non-Hispanic White, mean age=49.1 years). The study aimed to 1) provide a descriptive overview of rates of ACEs in this unique sample of adults with potentially high psychological vulnerability and 2) assess associations between ACEs, weight stigma, and psychological well-being. Over three-fourths of participants (76.2%) reported experiencing at least one ACE. The total number of ACEs was significantly associated with more frequent experiences of and greater distress about weight stigma during childhood, as well as higher current perceived stress. Experiencing weight stigma for the first time in childhood was also associated with more reported ACEs. ACEs of abuse were associated with more lifetime reported experiences of weight stigma and greater internalization, use of eating as a strategy to cope with weight stigma, and higher perceived stress. These findings have implications for early identification of and tailored interventions for individuals who have experienced adverse events and weight stigma at a young age.

Six-Month Follow-up from a Randomized Controlled Trial of the Weight BIAS Program.

OBJECTIVE: The aim of this study was to investigate the 6-month nonintervention follow-up effects of a cognitive behavioral intervention for weight bias internalization (WBI; i.e., self-stigma) combined with behavioral weight loss (BWL). METHODS: Adults with obesity and elevated WBI were previously randomized to receive BWL alone or in combination with the Weight Bias Internalization and Stigma program (BWL + BIAS). Participants attended weekly group meetings for 12 weeks, followed by two biweekly and two monthly meetings (26 weeks total). Follow-up assessments were conducted at week 52. Changes on the Weight Bias Internalization Scale and Weight Self-Stigma Questionnaire at week 52 were the principal outcomes. Other outcomes included changes in eating, coping, and weight. RESULTS: Of 72 randomized participants, 54 (75%) completed week 52 assessments. Linear mixed models showed improvements across groups, but no significant differences between groups, in week 52 change on the Weight Bias Internalization Scale (P = 0.25) or Weight Self-Stigma Questionnaire (P = 0.27). BWL + BIAS participants reported significantly greater benefits than BWL participants on measures of eating and affective coping with weight stigma. Percent weight loss at week 52 did not differ significantly between groups (BWL + BIAS = -3.1% [SE 1.0%], BWL = -4.0% [SE 1.0%], P = 0.53). CONCLUSIONS: Reductions in WBI did not differ between groups at 6-month follow-up. Further research is needed to determine the potential benefits of a stigma-reduction intervention beyond BWL.

Effects of a cognitive-behavioral intervention targeting weight stigma: A randomized controlled trial.

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.
