“…Although it has not been previously discussed, this result is consistent with the original paper reporting mean FAS ordinal scores in community-dwelling adults ranging from 3.88 to 4.24 out of a maximum score of 5 (Alleva et al, 2017). The lowest mean FAS scores reported previously, in the validation of a Japanese translation, was 3.60 out of 5 (Namatame et al, 2022). Within the present study, data also showed mean FAS scores of 3.38±0.56.…”

“…Rasch validation of the FAS demonstrated that the FAS is unidimensional and has a good item and person fit. The finding of unidimensionality agrees with previous validation studies on the FAS that employed exploratory-to-confirmatory factor analyses (CFA; Cerea et al, 2021; Namatame et al, 2022; Sahlan et al, 2022; Swami et al, 2021). The Rasch analysis also allowed for specific analysis on the item and person fit, which has not been previously measured.…”

“…They also demonstrated good internal consistency, test-retest reliability, and correlations between body image and well-being or the lack thereof (Alleva & Tylka, 2021). Exploratory and confirmatory factor analysis has been conducted in the US, Europe, Asia, and Australia (Alleva et al, 2017; Linardon et al, 2020; Namatame et al, 2022), and validated translations of the FAS are available in Malay, Romanian and Farsi, Japanese and Italian (Cerea et al, 2021; Namatame et al, 2022; Sahlan et al, 2022; Swami et al, 2019, 2021). However, the Cronbach’s alpha and exploratory or confirmatory factor analysis used in these studies assess scales based on their ordinal level of measurement.…”

The Functionality Appreciation Scale (FAS) measures an appreciation of the individual for the functions their body can perform, regardless of physical limitations of the individual. To facilitate the use of this tool by researchers and clinicians, it is necessary to understand what normal scoring looks like in healthy adults, as well as validate the scoring of this scale. We analyzed the FAS using Rasch Measurement Theory. FAS responses, demographic data, and clinical questionnaires were collected by the Brain Body Mind Lab (University of Minnesota) from 567 community-dwelling adults recruited at the Minnesota State Fair, including 14 adults with spinal cord injury. We evaluated item and person fit, targeting, unidimensionality, person separation reliability (PSR), local item dependence (LID), and differential item functioning (DIF) for demographic and clinical characteristics. We found a significant ceiling effect (26.98%) and a positive person mean location of 3.28 +/- 2.10 logits, indicating the FAS is too easy for the community-dwelling adults in the US. PSR was 0.79, indicating a capacity to differentiate groups of people according to their ability level of functional appreciation. We also compared the person mean location of adults who did or did not participate in body awareness training. Adults who practiced body awareness training had a higher person mean location (4.28, Interquartile Range [IQR] = 3.96 logits) than those who did not (2.73, IQR = 3.34), indicating a higher functionality appreciation. Overall, FAS demonstrated good item and person fit, but the current version of FAS will require more difficult items to be added to improve the targeting of the scale for use in a general population.

“…As a more comprehensive review is outside the scope of the current paper, see Alleva and Tylka (2021) for an extensive review of theory, scales, and research related to functionality appreciation. Body functionality (as measured by the FAS) has been shown to be positively associated with engagement in sport (Soulliard et al, 2021), body appreciation, self-compassion (Alleva et al, 2017;Swami et al, 2019a), selfesteem (Swami et al, 2019(Swami et al, , 2021(Swami et al, , 2022Linardon et al, 2020;Cerea et al, 2021;Namatame et al, 2022;Sahlan et al, 2022), life satisfaction (Namatame et al, 2022), proactive coping (Alleva et al, 2017), physical and mental health, gratitude (Swami et al, 2021;Namatame et al, 2022), body esteem (Cerea et al, 2021), body image flexibility (Linardon et al, 2020), and intuitive eating (Soulliard and Vander Wal, 2019;Namatame et al, 2022), and negatively associated with depressive symptoms (Linardon et al, 2020;Sahlan et al, 2022), body dissatisfaction, disordered eating/eating disorder symptoms (Soulliard and Vander Wal, 2019;Cerea et al, 2021;Swami et al, 2021Swami et al, , 2022, body surveillance (Cerea et al, 2021), drive for muscularity (Swami et al, 2021), drive for thinness (Cerea et al, 2021), overvaluation of shape and weight (Linardon et al, 2020), and general distress (Cerea et al, 2021).…”

Body image is an integral aspect of the psychology of the self. Idealized body images are ubiquitous in both traditional media forms (e.g., magazines, television) and social media (e.g., Facebook, Instagram). The classic sociocultural model of body image (i.e., the Tripartite Influence Model) emphasizes pathways between idealized body norms, appearance comparisons, internalization of body ideals, and body dissatisfaction and its outcomes. We summarize the model and identify some issues to be addressed in future work, particularly in light of the immense popularity of social media. We review three topics that are not included in the sociocultural model but that provide a more complete picture of the influence of societal body norms on body image: (1) body shame, (2) positive body image, and (3) self-compassion. Research on the nature, assessment, and relevance of these constructs is reviewed in detail. In terms of clinical applications of these areas of research for individuals at risk of body dissatisfaction, we suggest assessing for and targeting body shame, cultivating facets of positive body image, and teaching strategies for developing self-compassion.

“…Speci cally, the FAS has shown excellent internal consistency reliability with a Cronbach's α of .86, good construct validity (e.g., a large correlation with body appreciation, r = .60), and measurement invariance by sex [2]. After the development of FAS, the FAS has been validated and shown good psychometric properties in both adolescent and adult samples from many different countries including adolescent populations in Iran [12], and adult populations in Australia [7], Italy [13], Japan [14], Malay [8], and Romania [6].…”

Purpose The present work examined the psychometric properties of the Functionality Appreciation Scale (FAS) among four Chinese samples of different ages. The invariance of the FAS across sex and age was also tested. Methods Exploratory and confirmatory factor analyses (EFA and CFA) were conducted to confirm the factorial structure of the FAS among the four Chinese samples of different ages, including middle school adolescents (n = 894, Mage = 12.17 years), high school adolescents (n = 1347, Mage = 15.07 years), young adults (n = 473, Mage = 21.95 years), and older adults (n = 313, Mage = 67.90 years), and the invariance of the FAS across sex and age. Cronbach’s α was used to measure internal consistency, while correlations with theoretically related measures were employed to assess construct validity. Results The FAS had a unidimensional structure and was invariant across sex and age groups. The FAS presented sound psychometric properties in all age groups by sex, with good internal consistency reliability [e.g., high Cronbach’s α values (.91 ~ .97)] and good construct validity. Moreover, group comparisons showed minimal sex differences in functionality appreciation. However, significant age differences were found in functionality appreciation, with older ages generally associated with higher functionality appreciation. Conclusion Overall, the FAS proved to be a sound instrument to be used in the Chinese context; and functionality appreciation was found to be higher in older adults than adolescents or young adults, suggesting the potentially important role of aging in functionality appreciation. Level of Evidence: Level V, cross-sectional descriptive study
