The Functionality Appreciation Scale (FAS) is increasingly used in diverse national and linguistic contexts. However, limited work has assessed the extent to which the instrument demonstrates measurement invariance and differential item functioning (DIF) across nations and respondent characteristics. Here, we examined measurement invariance and DIF of the FAS using archival data from adults in Colombia (Mebarak et al., 2023) and Spain (Zamora et al., 2024). Participants included 1420 (women n = 804, men n = 616) respondents from Colombia and 838 (women n = 415, men n = 423) respondents from Spain who completed translations of the FAS. Confirmatory factor analysis supported a unidimensional structure of the FAS in both national groups. Additionally, the FAS achieved full measurement invariance (up to latent mean invariance) across both groups. We also found that the FAS lacked DIF as a function of age, body mass index (BMI), and gender identity across both national groups. Older participants (relative to younger participants), men (relative to women), and participants with lower BMIs (relative to those with higher BMIs) had higher FAS scores. These results support the notion that the FAS is measuring a common underlying construct across these national groups and respondent characteristics.

Writing tasks that encourage an appreciation of body functionality can improve women\'s body image and may buffer against negative effects of idealised media exposure. However, no research has examined whether these tasks can serve as a coping strategy after idealised exposure. To this end, young adult women (N = 217, Mage = 21.63) recruited from an Australian university and general community completed a writing task after idealised media exposure, with state body image measures taken at baseline, post-exposure, and post-task. Women were randomly allocated to one of three writing tasks and asked to appreciate their body functionality, to focus on the previously viewed images (rumination), or to describe a frequently travelled route (distraction). Improvements on outcome measures were equally found across both the functionality and distraction condition. Only body appreciation uniquely improved in the functionality condition. The functionality task was rated more helpful but also more challenging. These findings add to the evidence base regarding the usefulness of functionality-based writing tasks for improving women\'s body image. They can offer immediate benefits when experiencing body image distress, as can distraction, and future research should explore their utility in driving more sustained and deeper ways of engaging with one\'s body long-term.

There has been considerable recent interest in and reference to body neutrality, despite limited scholarship on differences from existing constructs. Our study examined perceptions of body neutrality in 229 individuals (researchers, clinicians, eating disorder lived experience, general community). Questions explored definitions of body neutrality, its similarity and differences to other concepts, perceived benefits and risks of adopting a body neutrality approach, and ratings on the usefulness of proposed components. Participants defined body neutrality as adopting an accepting, non-judgemental approach to one\'s body, de-emphasising the importance of appearance, and viewing the body as a vessel that carries a person through life. Perceived benefits included it being more accessible than existing approaches and a useful coping strategy, while risks were that neutrality can be difficult to adopt in an appearance focused society and that it may prompt an apathetic response to self-care. Body neutrality was rated as conceptually similar to functionality appreciation, body acceptance, and body compassion, and definitions consistent with these terms were rated most favourably. Our findings show how body neutrality is perceived and used by experts and the general community. However, we question whether this conceptualisation is distinct from existing positive body image concepts.

Previous findings suggest that body appreciation increases with age, whereas body dissatisfaction remains constant across the lifespan. However, the reason for this phenomenon remains unclear. In the present study, we examined the role of functionality appreciation in the association between age and body appreciation among Japanese adults. A community sample of 280 Japanese women and men (20-79 years old) completed an online cross-sectional survey with measures of functionality and body appreciation. Simple mediation analysis (PROCESS; Model 4) demonstrated that age was positively related to body appreciation and this relationship was mediated by functionality appreciation, for women, but not for men. This finding suggests that increased functionality appreciation might be a strategy for increasing body appreciation as we age, but only among women and not among men. It is possible that the adaptive strategies employed by older women could be utilized by younger women. Thus, implementing interventions focused on the enhancement of functionality appreciation might be beneficial for young women.

Recent data suggest a close association between positive body image (PBI) and eating disorder recovery. Nevertheless, the specific mechanisms through which PBI may facilitate recovery from anorexia nervosa (AN) remain unknown. To advance understanding of these mechanisms, this study examined core indices of PBI within AN, exploring its association with emotion regulation and well-being outcomes. Data were collected from 159 female participants, 64 with AN diagnosis and 95 healthy controls (HCs), who completed measures of PBI (body appreciation, functionality appreciation, and body responsiveness), emotion regulation, and psychological well-being (depression, anxiety, stress, and psychological quality of life). The AN group reported lower levels of PBI and psychological well-being, along with greater difficulties in regulating emotions, relative to HCs. PBI variables significantly predicted emotion regulation and psychological well-being in AN, accounting for 36% to 72% of the variance, with body appreciation emerging as the strongest predictor. These findings lend credence to the view that PBI can serve as a catalyst for psychological health. We hypothesize that enhancing PBI can improve interoceptive awareness, which is crucial for emotion regulation and reducing maladaptive food-related coping. Emphasizing a mind-body connection in lifestyle could be a relevant element to consider for both treating and preventing AN.

Although positive body image is associated with mental and physical health benefits, there is a relative dearth of research investigating the psychometric properties of commonly used measures of positive body image among Hispanic/Latina women in the United States. The current study explored the psychometric properties of the Body Appreciation Scale-2 (BAS-2; Tylka & Wood-Barcalow, 2015a) and the Functionality Appreciation Scale (FAS; Alleva et al., 2017) in undergraduate women. Altogether 565 undergraduates (n = 386 Hispanic/Latina; n = 179 non-Hispanic White [NHW]) completed the BAS-2, FAS, and demographic questionnaires. Confirmatory factor analysis (CFA) and measurement invariance testing across ethnicity was conducted on each measure. The CFA confirmed the 1-factor, 10-item model of the BAS-2 among Hispanic/Latina women but indicated a less than adequate model fit for the FAS which improved after correlating the residuals of items 6 and 7. Measurement invariance testing revealed evidence of partial scalar invariance of the BAS-2 and full invariance of the FAS across ethnicity. There were no significant mean differences between groups on the measures. These analyses indicate acceptable psychometric properties of the BAS-2 and FAS among Hispanic/Latina women. Nonetheless, they did suggest potentially meaningful group differences in how these items behaved, which warrant further exploration.

Functionality appreciation and body compassion are empirically supported concepts that can help one to view their body in different and compassionate ways. However, they have yet to be applied to eating disorder (ED) samples and therefore it is important to explore the perceived benefit, risk, and nuance in this population. Semi-structured interviews (N = 25) were conducted with treatment providers, those with a lived experience of an ED, or history of body image distress. Usefulness, applicability, potential risks, benefits, and desired delivery format were probed. Thematic analysis was used. Participants reported that compassion and functionality approaches were useful, complement existing treatment approaches, and important for early intervention. Although considered safe, caveats were noted for ED samples, including introducing content at the right time (e.g., when medically stable), and when having the cognitive flexibility to think about one\'s body in different ways. For example, functionality appreciation could trigger thoughts about what one\'s body cannot do while compassion may allow for normalising negative thoughts. Both concepts were viewed as useful and safe to support positive body image at a community level and can be used with ED samples with additional support. This insight from potential users helps with co-design of appropriate content.

In this position paper, we review nonacademic and academic discourse on body neutrality, a recent concept that has spread from social media platforms into scientific publications. This discourse has (inaccurately) promulgated that body neutrality is distinct from and more realistic than positive body image and body positivity. We identify and challenge 10 myths found within this discourse: (1) positive body image and body positivity are the same and therefore interchangeable, (2) positive body image isn\'t realistic or attainable, (3) we should forget about body positivity and positive body image, (4) body neutrality is a new way of thinking about body image, (5) body neutrality is unique from positive body image and positivity, (6) body neutrality is a more realistic and inclusive alternative to positive body image and body positivity, (7) body neutrality is different from positive body image but we can still use the research on positive body image to support body neutrality, (8) body neutrality is a midpoint between negative body image and positive body image, (9) striving for body neutrality is sufficient, and (10) appearance can be disregarded. We offer recommendations applicable to researchers, clinicians, media, and the general public interested in body neutrality.

BACKGROUND: The Functionality Appreciation Scale is a 7-item measure of an individual\'s appreciation of his or her body for what it can do and is capable of doing. While this instrument has been increasingly used in intervention-based research, its psychometric properties have not been extensively studied in non-English-speaking populations. The psychometric properties of a novel Spanish translation of the FAS were examined.
METHODS: An online sample of 838 Spanish adults (mean age = 31.79 ± 11.95 years, 50.48% men) completed the Spanish FAS and validated measures of body appreciation, eating disorder symptomatology, intuitive eating, and life satisfaction.
RESULTS: Exploratory factor analysis supported a 1-dimensional factor structure of the FAS, which was further supported by confirmatory factor analysis (SBχ²(14) = 83.82, SBχ²normed = 1.48, robust RMSEA = 0.094 (90% CI = 0.074, 0.115), SRMR = 0.040, robust CFI = 0.946, robust TLI = 0.924). Invariance across genders was shown, and there were no significant differences according to gender (t(417) = 0.77, p =.444, d = 0.07). Construct validity was also supported through significant associations with the other measures of the study. Incremental validity was established in women. Thus, appreciation of functionality predicted life satisfaction over and above the variance accounted for by other body image and eating disorder-related measures (F(4, 399) = 18.86, p <.001, ΔR2 = 0.03).
CONCLUSIONS: These results support the psychometric properties of the Spanish FAS and demonstrate the importance of the appreciation of functionality in relation to a healthier body image and psychological wellbeing.

Given the prevalence of body dissatisfaction among young people, which tends to persist into adulthood, a need exists for large-scale interventions that address this problem. Film has been identified as a resource that is well-suited to large-scale dissemination, which can achieve broad impact and reach. Embrace Kids, a film aimed at improving young people\'s body image, is one such resource. To evaluate the film\'s impact on body image, 55 children (M = 10.59, SD = 1.49) and 47 adults (M = 43.75, SD = 8.54) were recruited from the Australian general public to complete a brief survey before and after viewing the film. After viewing the film, significant increases in state body appreciation, state functionality appreciation and state self-compassion were reported for children (d = 0.46 - 0.61) and adults (d = 0.88 - 1.08). They supported the safety of the film by indicating that it did not make them more concerned about their appearance. Findings provide initial support for the film as a scalable intervention that can be safely task-shifted to non-professional audiences. Future research directions include comparing the effect of Embrace Kids against a control film, and testing the longitudinal impact of the film on trait body image.
