“…While some studies found positive and moderate associations (Lillis et al, 2009(Lillis et al, , 2010(Lillis et al, , 2011, others failed to find significant correlations (e.g., Weineland et al, 2012). On the other hand, BMI has been found to be related to lower physical functioning (QoL dimension), but not with psychosocial status and social adjustment (e.g., Mannucci et al, 1999).…”

“…Overall, internalized weight stigma was found to be closely related to the unwillingness to stay in contact with, and attempts to control unwanted weight-related internal experiences (Lillis et al, 2010;. In turn, research has been unveiling the pervasive role of experiential avoidance patterns in dealing with eating and weight difficulties (Forman et al, 2007;Lillis & Hayes, 2008;Lillis, Hayes, & Levin, 2011;Weineland, Lillis, & Dahl, 2012).…”

The role of weight self-stigma on the quality of life of women with overweight and obesity: A multi-group comparison between binge eaters and non-binge eaters

Weight self-stigma is conceptualized as a multidimensional concept involving experiences of shame, self-devaluation and the perception of being discriminated against in social situations due to one's weight. It has been associated with experiential avoidance, unhealthy eating behaviours, binge eating and diminish quality-of-life (QoL). The current study aims to explore the mediation effect of weight-related experiential avoidance on the relationship between weight self-stigma and obesity-related QoL in women with and without binge eating (BE).The sample comprised 282 women with overweight or obesity, from which 100 presented BE symptoms. Sample's mean age was 44.24 (SD = 11.30), with a mean BMI of 31.40 (SD = 4.53). Participants completed a set of self-reported measures regarding BE symptoms, weight self-stigma, weight-related experiential avoidance and QoL.Results from path analysis supported the mediation of weight-related experiential avoidance on the relationship between weight self-stigma and QoL, even when controlling for BMI. The model accounted 58% of QoL variance. Furthermore, the multi-group analysis revealed that the model was not invariant for both groups. The analysis of the critical ratios showed that the path from weight-related experiential avoidance to QoL was stronger for the BE group. Also the model only explained 39% of QoL for the group without BE and 65% of QoL for the BE group.This study highlights the pervasive role of weigh self-stigma, particularly fear of being discriminated and weight-related experiential avoidance on obesity-related quality-of-life, especially for those women with BE. Additionally, it supports that interventions should focus not only in weight loss but also in improving individual's QoL, promoting the development of adaptive emotional regulation strategies.

“…Indeed the authors stated that the factorial structure of AAQW still needed further analysis. The original study suggested a unifactorial structure (Lillis & Hayes, 2008), however a more recent study attempted to validate the AAQW for use with bariatric surgery patients and suggested that a five factor structure might be appropriate in that context (Weineland et al, 2012). However, three of the identified factors presented low internal consistencies (ranging between .44 to .67) and only 20 items of the original 22 were retained in the factor structure found.…”

“…Studies using the original 22-item version of the AAQW have found that weightrelated experiential avoidance is associated with general psychopathology, body dissatisfaction, disordered eating attitudes and behaviors, binge eating symptoms and diminished quality of life (Cardoso, 2014;Lillis & Hayes, 2008;Lillis et al, 2009;Lillis, Hayes, & Levin, 2011;Weineland et al, 2012). Furthermore, Lillis et al (2009) found that weight-related experiential avoidance mediated the impact of a 1-day ACT workshop on weight, weight self-stigma, psychopathological symptoms and healthrelated quality of life.…”

Experiential avoidance, defined as attempts to control or change unwanted internal experiences when doing so causes harm, has been consistently associated with physical and mental health problems and has been traditionally measured using the Acceptance and Action Questionnaire. Several studies have highlighted the importance of developing content-specific measures to better capture relevant processes for specific populations. One such measure is the Acceptance and Action Questionnaire for WeightRelated Difficulties (AAQ-W), which measures experiential avoidance of unwanted weight related thoughts, feelings and actions. The AAQW factor structure still requires further examination.The present study aims to contribute to the further development of the AAQW by conducting a confirmatory factor analysis (CFA) based on the existent factor structures and testing the measurement invariance across groups, through a multi-group analysis.2 Three distinct samples were used: the CFA used 215 women from the general population with BMI < 25 (sample 1); 210 overweight or obese treatment seeking (sample 2); AAQW's temporal stability and sensitivity to change was assessed using a sample of 58 overweight and obese women enrolled in Kg-Free (sample 3). Results supported a revised and shorter version of the AAQW (10 items) that we call AAQW-R (revised) with a three-factor structure (food as control, weight as barrier to living, weight-stigma) that showed a good fit to the data. Also, the measurement invariance across groups was confirmed. Finally, AAQW-R proved to be a reliable, stable measure and sensitive to clinical changes. Overall, this study offers new advances in the assessment of weight-related experiential avoidance, proposing a revised version of the AAQW. Moreover, it provides evidence for the usefulness of the AAQW-R both in general and clinical populations.

“…This result is in accordance with previous studies regarding other AAQ versions (general and context specific) that also point to the unidimensionality of psychological (in)flexibility assessed through experiential avoidance or acceptance (as an alternative to experiential avoidance) of negative private events, such as: the English (AAQ-I; Hayes et al, 2004;AAQ-II;Bond et al, 2011), Spanish (Mairal, 2004), Dutch (Boelen and Reijntjes, 2008), Portuguese (Pinto-Gouveia et al, 2012) and Italian versions (Pennato et al, 2013) of the AAQ, and the English (Lillis and Hayes, 2008) and Swedish versions (Weineland et al, 2013) of the AAQ-W, the AAQ-EX (Staats and Zettle, 2011) and the SA-AAQ (MacKenzie and Kocovski, 2010).…”
