Psychometric properties of the Spanish version of the functionality appreciation scale

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.

A pre-post evaluation of the impact of the Embrace Kids film on children's and adults' body image and self-compassion

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.

Self-objectification in Chinese pregnant women: The mixed role of functionality appreciation

Extensions of objectification theory to pregnant women are few and continued research is needed to better understand the psychological consequences of significant changes to physical appearance during pregnancy. Specific interests in this area include functionality appreciation which may be particularly relevant to pregnancy. Research in this area is also lacking representation of non-Western cultural contexts. To this end, we employed an online survey to assess objectification theory and functionality appreciation in Chinese pregnant women (N = 345). Correlations showed that higher body surveillance and body shame were associated with higher disordered eating and psychological distress, and higher functionality appreciation was associated with lower body surveillance, body shame, and disordered eating. Mediation analyses suggested that higher body surveillance was associated with higher body shame which, in turn, was associated with higher disordered eating and psychological distress. Main effects suggested a negative association between functionality appreciation and body shame, but moderation analyses suggested that higher functionality appreciation strengthened the positive association between body surveillance and body shame. Findings underscore objectification theory as a useful framework to understand eating and body image disturbances and psychological distress in Chinese pregnant women and outline future directions to clarify the temporal nature of these associations and the precise role of functionality appreciation.

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

The 7-item Functionality Appreciation Scale (FAS) measures the extent of an individual's appreciation of their body for what it can do and is capable of doing. Although the FAS has been widely used in diverse linguistic contexts, it has not been previously translated into Spanish. Here, we examined the psychometric properties of a novel Spanish translation of the FAS in Colombian adults. A total of 1420 university students from Colombia (804 women, 616 men) completed the FAS, as well as additional validated measures. Exploratory and confirmatory factor analyses in separate subsamples supported a unidimensional model of FAS scores. The FAS evidenced scalar invariance across gender identity, with men having significantly higher FAS scores than women (Cohen's d = 0.18). FAS scores were also found to have adequate composite reliability, as well as adequate convergent (significant associations with body appreciation, appearance evaluation, and eating disorder psychopathology) and concurrent validity (significant associations with self-esteem, life satisfaction, and gratitude). Functionality appreciation incrementally predicted life satisfaction in women, but not in men. Overall, these results suggest that the Spanish FAS is a psychometrically valid and reliable tool for the assessment of functionality appreciation in university-aged populations from Colombia.

Enhancing body image in motherhood: A randomised controlled trial of Expand Your Horizon among mothers of young children

Motherhood can increase vulnerability to body dissatisfaction, but positive body image interventions may mitigate this. Expand Your Horizon (Alleva et al., 2015), an online writing intervention, enhances functionality appreciation, an aspect of positive body image. The intervention's demonstrated efficacy and focus on body functionality indicate its potential use among mothers. However, its original 3-session format may be unfeasible for mothers alongside other commitments. Thus, we tested the impact of a single 15-minute Expand Your Horizon session on state body appreciation and functionality appreciation. Mothers (N = 143) of 0-10-year-olds were randomly allocated to either the intervention group, or an active control group. State body appreciation and functionality appreciation were assessed pre- and post-intervention. Trait self-compassion was tested as a potential moderator. Participants who completed Expand Your Horizon reported greater state body appreciation and functionality appreciation post-intervention than those in the control group. Self-compassion moderated the intervention's effect on state functionality appreciation, with effects strongest for those with lower levels of self-compassion. Overall, findings support the intervention's suitability for mothers, particularly those with low self-compassion. Practical implications include possibly tailoring Expand Your Horizon and similar interventions to benefit all mothers. Future research directions include longitudinal and qualitative designs, and extension to other specific populations.

Psychometric properties of a Dutch translation of the Functionality Appreciation Scale (FAS) among adults in the Netherlands

The Functionality Appreciation Scale (FAS; Alleva et al., 2017) measures functionality appreciation, the extent to which people appreciate their body for what it is able to do. We translated the FAS to Dutch and evaluated its factor structure and psychometric properties among 471 native Dutch speakers in the Netherlands (255 cisgender women, 204 cisgender men, 8 nonbinary, 1 "other," 3 "rather not say") who were between 18 and 85 years old. Participants completed the Dutch translation of the FAS, followed by questionnaires to assess additional variables of interest (body appreciation, appearance satisfaction, self-esteem, and gratitude). Exploratory factor analysis showed that Dutch FAS scores demonstrated a unidimensional factor structure. Dutch FAS scores demonstrated acceptable internal consistency and construct validity via their positive associations with the additional variables of interest. Dutch FAS scores also demonstrated gender invariance, and women reported higher functionality appreciation than men. Dutch FAS scores evidenced incremental validity for gratitude (but not self-esteem), and were inversely correlated with age and body mass index. Last, 2-week test-retest reliability of the Dutch FAS scores was supported. Overall, these findings provide support that the Dutch FAS is a psychometrically sound instrument to assess functionality appreciation among Dutch speaking adults in the Netherlands.

How exposure to body neutrality content on TikTok affects young women's body image and mood

Body neutrality aims to encourage a non-judgmental attitude towards the body and prioritize functionality over appearance. This study examined the impact of exposure to TikTok body neutrality content on young women's body image and mood. The sample comprised 189 undergraduate women (Mage = 19.25, SD = 1.98) who were randomly assigned to view one of three compilation TikTok videos on body neutrality, thin ideal, or art. Controlling for pre-test measures, results showed that women in the body neutrality group reported higher functionality appreciation and body satisfaction than women in the thin ideal and art control groups. Higher levels of positive mood and fewer upward appearance comparisons were reported by women in the body neutrality group relative to the thin ideal group. Although women in the body neutrality and thin ideal groups thought about their appearance and what they were wearing whilst viewing the videos, women in the body neutrality group reported that those thoughts were more positive than those in the thin ideal group. Findings demonstrate that brief exposure to body neutrality content on TikTok may induce immediate positive body image and mood in young women whilst providing a useful alternative to the unrealistic beauty standards popularized on such platforms.

Functionality appreciation is associated with improvements in positive and negative body image in patients with an eating disorder and following recovery

BACKGROUND

Research on body image in eating disorders has predominantly focused on negative body image, only recently shifting to positive body image. Findings suggest that enhancing positive body image can, amongst other things, serve as a protective mechanism against (re)developing a negative body image. One suggested way of enhancing positive body image is to focus on enhancing body functionality appreciation. Although studies show promising effects, this research is mainly conducted in non-clinical samples.

METHODS

The current study investigated the levels of positive and negative body image in an online community sample of patients with an eating disorder (PAT, n = 227), patients recovered from an eating disorder (REC, n = 102) and controls (HC, n = 175) (self-reported diagnosis, not confirmed). In addition, we tested whether body functionality appreciation was associated with appearance dissatisfaction (negative body image) and body appreciation (positive body image).

RESULTS

REC showed similar results to controls to most of the body image measures except for how much importance one places on their appearance (no different between REC and PAT), and how satisfied one is with certain body parts. For this measure, REC scored in-between PAT and HC. We further found functionality appreciation to be significantly associated with of both positive and negative body image, except for appearance evaluation in patients with an eating disorder.

CONCLUSIONS

This study showed a positive association between body functionality appreciation and positive body image and a negative association between body functionality appreciation and negative body image. Further research is required to investigate the effectiveness of interventions targeting body functionality appreciation in clinical settings.

Sport bodies: An examination of positive body image, sport-confidence, and subjective sport performance in Jamaican athletes

Guided by the Sport-Confidence Model, this study examined the associations among a positive body image, sport-confidence, and sport performance evaluations. Using a cross-sectional design, a purposive sample of 314 Jamaican athletes (male = 70.7%; Mage = 22.85; SD = 4.89) completed measures of body and functionality appreciation, sport-confidence, and subjective sport performance. Results from path analysis provided evidence for good model-data fit. Body (B = 9.03, p < .001) and functionality (B = 4.93, p = .036) appreciation exerted direct effects on sport-confidence. Sport-confidence exerted a direct effect on sport performance evaluations (B = 0.09, p < .001). Body (B = 0.79, CI95% [0.44, 1.17]) and functionality (B = 0.43, CI95% [0.05, 0.92]) appreciation exerted indirect effects on sport performance evaluations through sport-confidence. Results indicate that supporting the development of a positive body image in athletes may contribute to feelings of sport-confidence and positive performance outcomes.

The Chinese version of the Functionality Appreciation Scale: Psychometric properties and measurement invariance across gender and age

BACKGROUND

Functionality appreciation, as an important aspect of positive image, is associated with fewer body image disturbances, fewer disordered eating behaviors, and improved psychological well-being. However, it has been under-researched in Asian countries. The current work aimed to examine the psychometric properties of the Functionality Appreciation Scale (FAS) among four Chinese samples of different ages, and further examine measurement invariance and differences of the FAS across gender and age groups.

METHODS

Exploratory and confirmatory factor analyses (EFA and CFA) were conducted to examine the factorial structure of the FAS among four Chinese samples of different ages, including middle school adolescents (n = 894, M_age = 12.17 years), high school adolescents (n = 1347, M_age = 15.07 years), young adults (n = 473, M_age = 21.95 years), and older adults (n = 313, M_age = 67.90 years). The measurement invariance of the FAS across gender and age was examined. Internal consistency reliability and construct validity were evaluated.

RESULTS

The FAS had a unidimensional structure and was invariant across gender and age groups. The FAS presented sound psychometric properties in all age groups by gender, with good internal consistency reliability [e.g., high Cronbach's α values (.91 ~ .97)] and good construct validity (e.g., significant associations with body appreciation, body dissatisfaction, and disordered eating). Moreover, group comparisons showed minimal gender differences in functionality appreciation. However, significant age differences were found in functionality appreciation, with older ages generally associated with higher functionality appreciation.

CONCLUSION

Overall, findings suggest that the FAS is a sound instrument to be used in the Chinese context. Furthermore, functionality appreciation was found to be higher in older adults than adolescents or young adults, suggesting the potential important role of aging in functionality appreciation.

Functionality appreciation is inversely associated with positive psychotic symptoms in overweight/obese patients with schizophrenia

BACKGROUND

While the relationship between negative aspects of body image and positive schizophrenia symptoms was extensively investigated and is relatively well-established, there is a dearth of literature on the relationship between positive symptoms and positive aspects of body image, such as body appreciation and functionality appreciation, in patients with schizophrenia. This study aimed to (1) compare weight stigma, body and functionality appreciation between obese/overweight and normal-weight patients with schizophrenia, and (2) explore the associations between these variables and positive psychotic symptoms in the obese/overweight group.

METHOD

A cross-sectional study was conducted in the Psychiatric Hospital of the Cross, Lebanon during September 2022 recruiting selected in-patients diagnosed with schizophrenia. Patients were classified as overweight/obese if they had a BMI > 25 (N = 76 (37.25%), aged 55.57 ± 11.30 years, 42.6% females). The Weight self‑stigma questionnaire, the Functionality Appreciation Scale, and the Body Appreciation Scale, and the Positive and Negative Syndrome Scale (PANSS) were used.

RESULTS

No significant difference was found between overweight/obese and normal-weight patients for all variables, except for weight stigma; a significantly higher weight stigma score was significantly found in overweight/obese compared to normal-weight patient. In the bivariate analysis, higher functionality appreciation was significantly associated with higher positive PANSS scores. The results of the linear regression, taking the positive PANSS score as the dependent variable, showed that higher functionality appreciation (Beta = - 0.52) and higher social support (Beta = - 0.16) were significantly associated with lower positive PANSS scores, whereas having a secondary education level compared to illiteracy (Beta = 7.00) was significantly associated with higher positive PANSS scores.

CONCLUSION

Although based on cross-sectional data, these findings preliminarily suggest that higher functionality appreciation can help reduce the severity of positive psychotic symptoms in overweight/obese schizophrenia patients, and that interventions aimed at improving functionality appreciation could be regarded beneficial therapeutic targets in the treatment of psychosis.

Functionality appreciation and its correlates: Systematic review and meta-analysis

Functionality appreciation is a component of positive body image that refers to respecting and honoring the body for what it is capable of doing. A growing number of studies have investigated the features, correlates, and outcomes of functionality appreciation, yet a synthesis of this literature is missing. We conducted a systematic review and meta-analysis of research on functionality appreciation. Fifty-six studies were included (85 % cross-sectional). Random effects meta-analyses were performed on 21 cross-sectional correlates and on seven randomized trials of psychological interventions that assessed functionality appreciation as an outcome. Meta-analyses showed that functionality appreciation was consistently associated with fewer body image problems, lower levels of eating disorder symptoms, and better mental health and wellbeing. Functionality appreciation was unrelated to age and gender, but weakly (and negatively) related to body mass index. Preliminary evidence from prospective designs suggests that the appreciation of body functionality may promote adaptive eating patterns and prevent maladaptive eating and body image patterns over time. Psychological interventions designed to cultivate functionality appreciation in full or in part produced greater improvements in this construct than control conditions. Findings confirm that functionality appreciation is associated with numerous wellbeing constructs and could serve as a potentially useful target for intervention.

Psychometric properties of a Greek translation of the Functionality Appreciation Scale (FAS) in adults from the Republic of Cyprus

The Functionality Appreciation Scale is a widely used instrument for the measurement of an individual's appreciation of their body for what it can do and is capable of doing (i.e., functionality appreciation). In the present study, we examined the psychometric properties of a novel Greek translation of the FAS in Cypriot adults. A total of 448 women and 345 men from the Republic of Cyprus completed the FAS, as well as validated measures of body appreciation, appearance evaluation, and symptoms of disordered eating, and self-esteem. Exploratory and confirmatory factor analyses supported a unidimensional model of FAS scores, with all 7 items retained. Scores achieved scalar invariance across gender, with the gender difference in FAS scores not reaching significance. FAS scores were also found to have adequate composite reliability and convergent (significant associations with body appreciation, appearance evaluation, and symptoms of disordered eating) and concurrent validity (significant associations with self-esteem). Finally, functionality appreciation predicted self-esteem once the effects of all other variables had been accounted for, supporting incremental validity. Overall, these results suggest that the Greek FAS is a psychometrically valid tool for the assessment of functionality appreciation in adults from Cyprus.

Endometriosis and body image: Comparing people with and without endometriosis and exploring the relationship with pelvic pain

Qualitative studies have shown that people with endometriosis report feeling discontent with their bodies relating to the visual and functional effects of the disease. However, few studies exist which compare people with endometriosis to those without, leaving it largely unknown as to whether this discontentment differs from that regularly experienced by women. The current study therefore aimed to 1) quantitatively assess body image, namely appearance satisfaction and functionality appreciation, in people with and without endometriosis, and 2) explore the relationship between endometriosis-related pelvic pain and body image. Australians aged 18 and over were recruited for two groups: those with endometriosis (n = 312, 99 % female, M_age = 30.78, SD_age = 7.40) and a control group without suspected or diagnosed endometriosis (n = 74, 100 % female, M_age = 32.38, SD_age = 8.84). Participants completed an online survey consisting of measures of appearance satisfaction, functionality appreciation, and pelvic-pain impact. The endometriosis group demonstrated significantly poorer body image when compared to the control group, and endometriosis-related pelvic pain was shown to negatively correlate with body image. These findings demonstrate the likely negative effects endometriosis and pelvic pain have on body image and provide much needed insight to help develop interventions tailored to endometriosis.

Understanding the role of positive body image during digital interventions for eating disorders: Secondary analyses of a randomized controlled trial

Despite growing interest in the possible link between positive body image and eating disorder (ED) symptoms, little is known about what role this adaptive construct plays in ED treatment. This study investigated whether: (1) interventions principally designed to target ED psychopathology also lead to improvements in positive body image indices (i.e., body appreciation, functionality appreciation, and body image flexibility); (2) changes in ED symptoms correlate with changes in positive body image, both concurrently and prospectively; and (3) baseline positive body image levels moderate the degree of symptom improvement. Secondary analyses from a randomized controlled trial on digital interventions for EDs (n=600) were conducted. Intervention participants reported greater increases in the three positive body image constructs than the control group (ds=0.15-0.41). Greater pre-post reductions in ED psychopathology and binge eating were associated with greater pre-post improvements in positive body image indices. However, earlier reductions in ED psychopathology and binge eating did not predict later improvements in positive body image at follow-up. None of the positive body image constructs at baseline moderated degree of symptom change. Standard ED interventions can cultivate a more positive body image, although this is not explained by earlier symptom reduction. Understanding the mechanisms through which ED interventions enhance positive body image is needed.

Psychometric properties of an Arabic translation of the Functionality Appreciation Scale (FAS) in Lebanese adults

The Functionality Appreciation Scale is a widely used instrument for the measurement of an individual's appreciation of their body for what it can do and is capable of doing (i.e., functionality appreciation). Here, we examined the psychometric properties of a novel Arabic translation of the FAS. A sample of 826 Lebanese adults completed the FAS, as well as previously validated measures of body appreciation, disordered eating attitudes, orthorexia, and self-esteem. Exploratory and confirmatory factor analyses supported a unidimensional model of FAS scores, with all 7 items retained. Scores achieved scalar invariance across gender, with women reporting significantly greater functionality appreciation than men. FAS scores were found to have adequate composite reliability and adequate patterns of convergent and criterion-related validity. Additionally, functionality appreciation predicted self-esteem once the effects of all other variables had been accounted for, supporting incremental validity. Overall, these results suggest that the Arabic FAS is a psychometrically valid tool for the assessment of functionality appreciation. The availability of the Arabic FAS should facilitate improved understanding of the effectiveness of existing interventions designed to promote greater physical activity in the Lebanese context.

Psychometric properties of a Farsi translation of the Functionality Appreciation Scale (FAS) in Iranian adolescents

The 7-item Functionality Appreciation Scale (FAS; Alleva et al., 2017) measures an individual's appreciation of their body for what it can do and is capable of doing (i.e., functionality appreciation). However, few studies have assessed the psychometric properties of the FAS in non-English speaking populations and in younger age groups. Here, we examined the psychometric properties of a novel Farsi translation of the FAS in Iranian adolescent girls and boys. A sample of 828 Iranian adolescents completed the FAS alongside the Rosenberg Self-Esteem Scale and the Beck Depression Inventory-II. Participants were randomly split into a first split-half for exploratory factor analysis (EFA) or a second split-half for confirmatory factor analysis (CFA). The EFA broadly supported a 1-dimensional model of FAS scores, although one item had low item-factor loadings. The CFA indicated that both the 6- and 7-item models had adequate fit. In further analyses, we found that the 7-item unidimensional model was invariant across gender and that higher FAS scores were significantly associated with higher self-esteem and lower depressive symptoms, indicative of convergent validity. These results provide evidence that the Farsi translation of the FAS is reliable and valid for use in Iranian adolescent girls and boys.

Body image and eating behaviors: A latent profile analysis

Body image is multidimensional and less is known about how the combination of positive and negative body image relates to eating behaviors. We used a person-centered approach to identify profiles of body image and explore the relationship between profile membership, sex, age, race, and current marital status, and eating behaviors in a community sample of adults. We recruited 288 adults 18 and older living in the United States using Prolific Academic. Participants completed an online survey assessing body appreciation, functionality appreciation, body dissatisfaction, weight bias internalization, and adaptive and maladaptive eating behaviors. We used latent profile analysis to identify four distinct body image profiles: appreciation & mild dissatisfaction, functional appreciation & moderate dissatisfaction, strong dissatisfaction, and strong appreciation. Profile membership differed by sex with more women and younger adults in profiles higher in negative body image. The relationships between profiles and eating behaviors differed; the three profiles including negative body image had the lowest adaptive and highest maladaptive eating behaviors. The identification of clinically relevant profiles: (1) confirm positive and negative body image coexist, (2) identify high- and low-risk profiles of body image and eating behavior, and (3) offer preliminary suggestions for screening and tailoring preventive interventions.

Measurement invariance and psychometric properties of three positive body image measures among cisgender sexual minority and heterosexual women

Positive body image is a multidimensional construct consisting of various facets including body appreciation, body image flexibility, and functionality appreciation measured via the Body Appreciation Scale-2 (BAS-2), Body Image-Acceptance and Action Questionnaire-5 (BI-AAQ-5), and Functionality Appreciation Scale (FAS), respectively. Research has supported the unidimensional factor structure of these measures; however, invariance testing based on sexual identity has yet to be conducted. The study's primary aim was to assess the measurement invariance of the BAS-2, BI-AAQ-5, and FAS between sexual minority and heterosexual women. The secondary aim was to assess the psychometric properties of each positive body image measure among each sample. Participants were predominantly White, cisgender women who identified as a sexual minority (n = 310) or heterosexual (n = 360) and completed online questionnaires of positive body image, eating behaviors, and mental and physical health. Results supported invariance with no differences in BAS-2 or BI-AAQ-5 scores. A significant difference with a small effect size was found in FAS scores, with sexual minority women reporting lower FAS scores. Findings supported the BI-AAQ-5 and FAS's incremental validity on perceived mental health. Overall, results suggest that the BAS-2, BI-AAQ-5, and FAS scores can be compared among women of varying sexual identities.

Body image and quality of life in women with breast cancer: Appreciating the body and its functionality

Women with breast cancer often experience major physical changes, which can impact their body image and Quality of Life (QoL). Traditional assessments of body image implemented within breast cancer research focus solely on body dissatisfaction. This study explored the association between both positive and negative body image and QoL. Australian women (N = 123) within 5-years of a breast cancer diagnosis were invited to complete a web-based questionnaire including measures of body appreciation and functionality appreciation, cancer-specific measures of body dissatisfaction and QoL, and demographic, health and treatment/illness questions. All body image measures were significantly associated with QoL (p < .01). However, when body image variables were entered simultaneously as predictors of QoL (adjusting for comorbidity, treatment and employment), only body dissatisfaction was significantly associated with QoL (p < .001). Further analyses indicated this was due to shared variance in QoL between body and functionality appreciation, suggesting they assess highly related constructs within this population. Results indicate positive and negative components of body image are relevant to QoL within breast cancer populations; though, body dissatisfaction remained the strongest predictor of QoL indicating its pervasiveness. Future research should explore the development and use of breast cancer-specific measures of positive body image.

Psychometric validation of the Japanese version of the Functionality Appreciation Scale (FAS)

The Functionality Appreciation Scale (FAS; Alleva et al., 2017) is a widely adopted measure to assess appreciation for one's body and its capacity. In this study, we performed a psychometric validation of the Japanese translation of the FAS. Participants included an online sample of 750 Japanese individuals (20-70 years old), who completed the FAS and other previously validated measures of body appreciation, intuitive eating, gratitude, self-esteem, and life satisfaction. Moreover, the survey was conducted twice, 3 weeks apart, to determine test-retest reliability. Exploratory factor analyses replicated the unidimensional factor structure of the FAS, which was also verified by the confirmatory factor analysis. FAS scores had gender invariance, and demonstrated good internal consistency and test-retest reliability over the 3-week period. In addition, further analyzes indicated adequate construct, and incremental validity. These findings indicate that the Japanese version of FAS demonstrates good psychometric properties, and can be used to examine the importance of functionality appreciation for enhancing positive body image and healthy eating.

Psychometric properties of an Italian translation of the Functionality Appreciation Scale (FAS)

The Functionality Appreciation Scale (FAS; Alleva et al., 2017) is a widely used instrument for the measurement of individual's appreciation of their body for what it can do and is capable of doing (i.e., functionality appreciation). Here, we examined the psychometric properties of a novel Italian translation of the FAS. A sample of 950 Italian adults completed the FAS, as well as previously validated measures of body image (body appreciation, body esteem, body surveillance), disordered eating symptoms, and psychological well-being (self-esteem, general distress). Exploratory and confirmatory factor analyses supported a 1-dimensional model of FAS scores, with all 7 items retained. Scores achieved scalar invariance across gender, and the gender difference in latent FAS scores was not significant. FAS scores were found to have adequate internal consistency, test-retest reliability up to three weeks, and convergent and criterion-related validity through significant correlations with all additional constructs. However, evidence of incremental validity was weak, and likely reflected high nomological and conceptual similarity between functionality and body appreciation in this national context. Overall, these results provide strong evidence that scores on the Italian FAS are psychometrically valid, which may aid future development of interventions to promote more positive body image in Italian-speaking samples.

Psychometric properties of a Romanian translation of the Functionality Appreciation Scale (FAS)

The Functionality Appreciation Scale (FAS; Alleva et al., 2017) is a 7-item measure of an individual's appreciation of their body for what it can do and is capable of doing. Although the instrument is increasingly used in interventionist studies, its psychometric properties have been infrequently investigated outside Anglophone populations. Here, we examined psychometric properties of a novel Romanian translation of the FAS. An online sample of 959 Romanian adults (18-73 years old) completed the Romanian FAS, and validated measures of positive body image (body appreciation), negative body image (weight discrepancy in women, drive for muscularity in men), eating disorder symptomatology, and psychological well-being (self-esteem, gratitude). Exploratory factor analyses led to the extraction of a 1-dimensional model of FAS scores, which we confirmed using confirmatory factor analysis. FAS scores achieved scalar invariance across sex, but the sex difference in latent FAS scores did not reach significance (d = 0.15). FAS scores had adequate internal consistency and test-retest reliability up to four weeks, and further analyses provided evidence of convergent, construct, and incremental validity. These results support the psychometric properties of the Romanian FAS and present evidence of the importance of functionality appreciation in relation to healthier body image and psychological well-being.

"I appreciate your body, because…" Does promoting positive body image to a friend affect one's own positive body image?

Research has shown that individuals with a positive body image promote positive body image to others, yet also have close others who unconditionally accept their body and feel positively about their own body, too. This mutual interdependence between the individual and the environment with respect to positive body image has been termed reciprocity. Inspired by this research, we investigated whether promoting positive body image to others leads to improvements in one's own positive body image. To do so, undergraduate women (N = 154) were randomised to write a letter to a friend, expressing either appreciation for their friend's body functionality (experimental group) or appreciation for their shared memories (control group). Participants completed pretest and posttest measures of state functionality appreciation and state body appreciation, and filler items. Unexpectedly, there were no group differences in state functionality appreciation and state body appreciation. Instead, participants within both groups experienced medium to large improvements in state functionality appreciation and state body appreciation. To our knowledge, this is the first study to test the effects of promoting positive body image to others. Future research can shed further light on the effects of promoting positive body image to others in particular, and on the phenomenon of reciprocity more broadly.

Body functionality: A review of the literature

Body functionality describes everything that the body is able to do, across diverse domains (e.g., bodily senses, creative endeavours). Nearly a decade ago, leading scholars identified research on body functionality as a priority for the body image field. The field has responded, as shown by the recent rise of body functionality research. We considered this an opportune time to (a) define body functionality (what it is and is not); (b) present theoretical frameworks of body functionality; (c) articulate first-generation and current measures relating to body functionality; (d) offer functionality-focused body image interventions that can improve appreciation for one's body functionality (and body image more broadly); (e) summarise additional areas of research related to body functionality and positive body image; and (f) provide considerations and directions for future research and interventions incorporating body functionality. Research has underscored body functionality as a valuable construct with respect to positive body image and well-being, particularly when individuals appreciate what their bodies can do and conceptualise their body functionality holistically. Yet, the experience of body functionality is nuanced across social identities. Overall, the field has greatly advanced knowledge about body functionality, and we are excited to see the next generation of research that emerges.

The effects of yoga on functionality appreciation and additional facets of positive body image

This study investigated the effects of yoga on functionality appreciation, and the potential mechanisms that could explain the impact of yoga on additional facets of positive body image. Young adult women (N = 114; M_age = 22.19) were randomised to a 10-week Hatha yoga programme or waitlist control group. Participants completed measures of functionality appreciation, body appreciation, body compassion, appearance evaluation, self-objectification, and embodiment at Pretest, Midtest, Posttest, and 1-month Follow-Up. Follow-up data could not be analysed due to high levels of attrition. The remaining data showed that, compared to the control group, women in the yoga programme experienced lower self-objectification at Midtest and greater embodiment over time. Further, all participants experienced improvements in body appreciation, body compassion, and appearance evaluation over time, regardless of their assigned group. Lower self-objectification contributed to improvements in body appreciation and body compassion. In addition, greater embodiment contributed to improvements in body appreciation, body compassion, and appearance evaluation. Contrary to our expectations, yoga did not lead to increased functionality appreciation, nor was functionality appreciation a mediator of the impact of yoga on positive body image. Instead, lower self-objectification, and greater embodiment, drove improvements in positive body image.

Greater gastric interoception is associated with more positive body image: Evidence from adults in Malaysia and the United Kingdom

Gastric interoception refers to the processing of sensory stimuli originating in the gut. Previous research has found that gastric interoception (measured using a water load task) is associated with drive for thinness in young Western women. However, associations with broader facets of body image and in diverse national groups have not been previously investigated. To address these issues, we asked samples of adults in the United Kingdom (UK; N = 91, women n = 54) and Malaysia (N = 100, women n = 50) to complete a 2-stage water load task (WLT) and measures of positive body image (i.e., body appreciation, functionality appreciation). The results indicated that a greater change in the intensity of self-reported WLT-related sensations was associated with significantly higher body appreciation and functionality appreciation after accounting for gender identity, body mass index, and national group. Behavioural performance on the WLT was significantly associated with body appreciation and functionality appreciation for the Malaysian sample, but not the UK adults, after accounting for gender identity and body mass index. These findings extend previous research by demonstrating that there are significant associations between facets of gastric interoception and previously unexplored facets of body image in both Western and non-Western settings.

Assessing the measurement invariance of two positive body image instruments in adults from Malaysia and the United Kingdom

Despite the growth of positive body image research in recent years, our understanding of the construct across different national contexts remains limited. Here, we investigated measurement invariance of the Body Appreciation Scale-2 (BAS-2) and the Functionality Appreciation Scale (FAS) across ethnically homogenous groups of adults from Malaysia (n = 815, women n = 403) and the United Kingdom (UK; n = 596, women n = 416). Using multi-group confirmatory factor analysis, partial scalar invariance was supported for scores on both measures after fixing the intercepts for BAS-2 Items 6 and 8, and FAS Item 4. Next, we examined differences in latent scores across nationality and gender. The results of an analysis of covariance (with age and body mass index as covariates) indicated a significant nationality by gender interaction: Malaysian women had higher scores than Malaysian men on both the BAS-2 and FAS, but UK men had higher scores than UK women. There were also significant main effects of nationality (Malaysian participants had significantly higher body appreciation and functionality appreciation than UK participants) and gender (men had significantly higher body appreciation than women). These findings are discussed in terms of cross-national and gendered understandings of positive body image.

Sexual function in hook-up culture: The role of body image

Hook-up mobile apps are increasing in popularity and research suggests sexual function may be lower among those who hook-up compared to those who have sex in a longer-term relationship. Sexual function is an important predictor of well-being; however, we know little about the psychosocial antecedents of sexual function, such as body image, among those who use hook-up apps. The current study aims to examine two measures of positive body image and one measure of body image self-consciousness during intimate activity among a sample of adult women and men who have hooked up in the previous month using a hook-up mobile app (N = 243). Our results suggest that higher body image self-consciousness during intimate activity was related to lower sexual function composite score and several specific domains (i.e., pain, arousal, orgasm, and lubrication) among women. Higher body appreciation was related to higher sexual satisfaction among women. Higher body image self-consciousness during intimate activity was related to higher erection difficulty, but not ejaculation difficulty, among men. These findings highlight the nuanced nature of body image and sexual function and provide further evidence that interventions for women and men aiming to improve some body image constructs may improve sexual function as well.

Translation and validation of a Bahasa Malaysia (Malay) version of the Functionality Appreciation Scale

The Functionality Appreciation Scale (FAS; Alleva et al., 2017) is a 7-item measure of an individual's appreciation of their body for what it can do and is capable of doing. To date, its psychometric properties have not been examined beyond the parent study and outside English-speaking samples. To rectify this, we examined the psychometric properties of a Bahasa Malaysia (Malay) translation of the FAS. An online sample of 815 Malaysia citizens completed a Malay translation of the FAS, along with validated measures of body appreciation, weight discrepancy, drive for muscularity, perceived pressure from and internalisation of appearance ideals, self-esteem, and trait mindfulness. Exploratory factor analyses supported a 1-dimensional factor structure of FAS scores, which was upheld using confirmatory factor analysis. FAS scores were also invariant across sex and there was no significant sex difference in scores. Construct validity was generally supported through significant associations with the additional measures included in the study. Incremental validity was also established insofar as functionality appreciation predicted self-esteem over-and-above the variance accounted for by other body image measures. The availability of the Malay FAS will be of use to scholars in Malaysia, but establishing cross-linguistic invariance will be an important next step.

Multiple dimensions of interoceptive awareness are associated with facets of body image in British adults

Previous research has identified a relationship between interoception and body image, where lower interoceptive awareness (IA) is associated with negative body image. However, relationships between facets of interoception and positive body image remain unexplored, and men and older adults remain underrepresented. To overcome these limitations, we assessed relationships between multiple dimensions of interoceptive awareness (IA) and multiple facets of body image in community adults. An online sample of 646 British adults (447 women) aged 18-76 years completed the Multidimensional Assessment of Interoceptive Awareness (MAIA), the Body Appreciation Scale-2, the Functionality Appreciation Scale, the Authentic Pride subscale from the Body and Appearance Self-Conscious Emotions Scale, and the Appearance Orientation and Overweight Preoccupation subscales from the Multidimensional Body-Self Relations Questionnaire. Hierarchical regressions revealed significant predictive relationships between IA and all five facets of body image after controlling for sex, body mass index, and age. In the final models, the MAIA subscales emerged as significant predictors for at least one facet of body image, with the exception of the MAIA Body Listening subscale. These findings extend previous work by demonstrating significant relationships between IA and previously unexplored facets of body image, which may hold promise for practitioner-based interventions.

Examining positive body image, sport confidence, flow state, and subjective performance among student athletes and non-athletes

The primary purpose of the present study was to examine differences in positive body image, specifically body appreciation and functionality appreciation, between student athletes and non-athletes. A secondary purpose was to examine the relationships between positive body image and other sport-related variables. Seventy-nine National Collegiate Athletic Association (NCAA) Division I student athletes (M_age = 19.79, SD = 1.13) and 175 non-athletes (M_age = 19.38, SD = 1.81) completed measures of body appreciation and functionality appreciation. The athletes further completed measures of sport confidence, flow state, and subjective sport performance. Student athletes reported higher levels of both facets of positive body image. Significant relationships were also found between positive body image and the sport-related variables. The present results contribute novel findings to the positive body image literature and potential implications for coaches to encourage a culture that focuses less on body appearance and more on cultivating positive body image.

community women and men

Body functionality has been identified as an important dimension of body image that has the potential to be useful in the prevention and treatment of negative body image and in the enhancement of positive body image. Specifically, cultivating appreciation of body functionality may offset appearance concerns. However, a scale assessing this construct has yet to be developed. Therefore, we developed the Functionality Appreciation Scale (FAS) and examined its psychometric properties among three online community samples totalling 1042 women and men (ns=490 and 552, respectively). Exploratory factor analyses revealed a unidimensional structure with seven items. Confirmatory factor analysis upheld its unidimensionality and invariance across gender. The internal consistency, test-retest reliability, criterion-related, and construct (convergent, discriminant, incremental) validity of its scores were upheld. The FAS is a psychometrically sound measure that is unique from existing positive body image measures. Scholars will find the FAS applicable within research and clinical settings.
