Body Shape Questionnaire-34 (BSQ) and Functionality Appreciation Scale (FAS) - pertinent body image screening tools: Creation and validation of Polish language versions

Abstract

Objective: Body image is defined as the perception of one's own body. While positive body image has a positive impact on quality of life, self-dissatisfaction may lead to depression, anxiety and low self-esteem. Body image might be quantified and evaluated: relevant instruments include the Body Shape Questionnaire (BSQ) and the Functionality Appreciation Scale (FAS). This study was designed to translate and evaluate the psychometric properties of the Polish versions of these instruments. Methods: Translation (both forward and backward) from the original English versions of the questionnaires met international standards. Internal consistency and test-retest reliability are reported from 89 participants for the BSQ and 103 for the FAS. The participants also completed the Polish versions of the Body Image Quality of Life Inventory (BIQLI) and the Body Appreciation Scale-2 (BAS-2) to explore convergent validity. Results: Both, Polish versions of the BSQ and the FAS demonstrated good internal consistency and reproducibility. Convergent validity revealed a moderate relationship between the BSQ and the BIQLI scores, and a strong one between the FAS and the BAS-2 scores. Conclusion: Polish versions of both BSQ and FAS questionnaires showed sufficiently strong psychometric properties to support their use in clinical and research work with Polish speaking patients.

Genetic polymorphisms and their association with neurobiological and psychological factors in anorexia nervosa: a systematic review

“…The findings revealed a significant association between skin conductance response frequency and the presence of the BDNF Met genotype. In addition, the Body Shape Questionnaire (BSQ) was also used, which is a self-report tool that assesses body image concerns and dissatisfaction ( Yurtsever et al, 2022 ). According to the study, individuals with AN experienced more positive feelings when processing images of underweight bodies ( Clarke et al, 2016 ), suggesting that underweight stimuli evoked a distinct emotional reaction in patients with AN and could be related to their body image perception.…”

The Functionality Appreciation Scale (FAS): psychometric properties and results of the Dutch version in a community sample and a sample of women with eating disorders

“…Given that therapeutic interventions have been developed in the eld of EDs, which also focus on [7,48] or entirely address [8] functional aspects of body image to enhance body satisfaction, it is essential to be able to measure body functionality before, during and after these interventions. For this reason, we recommend, along with Yurtsever et al, [49], further research exploring the sensitivity to change of the FAS. Another limitation in our study was the disproportionate distribution of the various types of EDs in our clinical sample.…”

Psychometric properties of a Spanish translation of the Functionality Appreciation Scale (FAS) in adults from Colombia

“…Beyond factorial validity, most test adaptation studies have also shown that the FAS is invariant across gender identity (see also Marmara & Zarate, 2022), with gender differences in functionality appreciation generally non-significant or negligible (see Linardon et al, 2023). Moreover, where additional indices of validity have been tested (see also Yurtsever et al, 2021), studies have robustly supported the concurrent (e.g., positive associations with other facets of positive body image and negative associations with eating disorder psychopathology), convergent (e.g., positive associations with indices of psychological well-being, such as self-esteem and life satisfaction), and incremental validity of the scores on the FAS (e.g., functionality predicts psychological well-being over-and-above other indices of positive body image). Overall, these findings across national groups are consistent with the conclusions of a recent meta-analysis of the correlates of functionality appreciation, which found that functionality appreciation is consistently associated with fewer body image problems, lower levels of disordered eating, and more positive mental health (Linardon et al, 2023).…”
