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, M age = 49 years, 90.5% women, 70.5% White, 24.8% Black, M BMI = 38 kg/m 2 ) 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
Objective
Food addiction is a phenotype characterised by an addiction‐like attraction to highly processed foods. Adolescence is a sensitive period for developing addictive disorders. Therefore, a valid measure to assess food addiction in adolescents is needed. Accordingly, the aim of the study was to establish a categorical scoring option for the full version of the Yale Food Addiction Scale for Children 2.0 (YFAS‐C 2.0), and to psychometrically validate the full YFAS‐C 2.0.
Method
The data stem from the Food Addiction Denmark (FADK) Project. Random samples of 3750 adolescents from the general population aged 13–17 years, and 3529 adolescents with a history mental disorder of the same age were invited to participate in a survey including the full version of the YFAS‐C 2.0. A confirmatory factor analysis was carried out and the weighted prevalence of food addiction was estimated.
Results
The confirmatory factor analysis of the YFAS‐C 2.0 supported a one‐factor model in both samples. The weighted prevalence of food addiction was 5.0% in the general population, and 11.2% in the population with a history of mental disorder.
Conclusions
The full version of the YFAS‐C 2.0 is a psychometrically valid measure for assessing clinically significant food addiction in adolescents.
