Measuring avoidance and inflexibility in weight related problems.

Psychometric properties of the Portuguese version of the Acceptance and Action Questionnaire–Trauma Specific (AAQ-TS): A study with Portuguese Colonial War Veterans

“…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).…”

“…For this reason, assessment instruments should be developed for specific areas (Lillis and Hayes, 2008), such as those related to traumatic experiences.…”

“…This was followed by different versions of the AAQ developed for specific problems and disorders. These include measures such as the Acceptance and Action Questionnaire for Weight-Related Difficulties (AAQW; Lillis and Hayes, 2008), the Voices Acceptance and Action Questionnaire (VAAS, Shawyer et al, 2007), the Social Anxiety-Acceptance and Action Questionnaire (SA-AAQ; MacKenzie and Kocovski, 2010) and the Acceptance and Action Questionnaire for Substance Abuse (AAQ-SA; Luoma et al, 2011). In turn, Braekkan and colleagues developed the initial Acceptance and Action Questionnaire-Trauma Specific (AAQ-TS, personal communication) for Post-Traumatic Stress, to assess psychological (in)flexibility and EA related to trauma.…”

Testing the model of psychological flexibility in the Serbian cultural context: The psychometric properties of the acceptance and action questionnaire

“…Although higher levels of experiential avoidance have been associated with higher risks of many forms of psychopathology (Levin et al, 2014), the potential of the AAQ-II in discriminating clinical and nonclinical samples has not been adequately demonstrated (Karekla & Michaelides, 2017;Tyndall et al, 2019). In the past decade, there has also been a noticeable trend in developing variations of the AAQ in more disorder-specific manner, in order to evaluate the role of experiential avoidance in particular conditions, including psychosis (Shawyer et al, 2007), chronic pain (Vowles, McCracken, McLeod, & Eccleston, 2008), social anxiety (MacKenzie & Kocovski, 2010), body-image (Sandoz, Wilson, Merwin, & Kellum, 2013), substance abuse (Luoma, Drake, Hayes, & Kohlenberg, 2011), smoking dependence (Gifford et al, 2002), and weight-related issues (Lillis & Hayes, 2008). As much as their results are promising and highlight the importance of experiential avoidance, most of this research was conducted with AAQ, i.e., before the development of the AAQ-II.…”
