The construct of body acceptance by others (i.e., the degree to which an individual perceives acceptance for their appearance by others) is central to conceptual models of positive body image and adaptive eating styles. It is typically measured using the 10-item Body Acceptance by Others Scale (BAOS; Avalos & Tylka, 2006), but emerging research has suggested that a unidimensional model of BAOS scores may be unstable. Here, we examined the factor structure of BAOS scores in a sample of adults from the United Kingdom (N = 1148). Exploratory factor analyses indicated that BAOS scores reduced to two dimensions in women, of which only a primary 6-item factor was stable. In men, all 10 items loaded onto a primary factor. However, the results of confirmatory factor analyses indicated that both models of BAOS scores had poor fit. Although both the unidimensional 10-item and 6-item models had adequate internal consistency, our results are suggestive of factor structure instability. We conclude by suggesting ways in which future research could revise the BAOS to improve its factorial stability and validity.
The construct of intuitive eating is most often measured using the 23-item Intuitive Eating Scale-2 (IES-2). Here, we examined the psychometrics of a Romanian translation of the IES-2. Eight-hundred-and-thirty Romanian adults completed the IES-2 along with measures of positive body image, symptoms of disordered eating, and psychological well-being. Exploratory factor analyses (EFAs) with a split-half subsample (n = 420) indicated that IES-2 scores reduced to three factors in women and four in men, both of which diverged from the parent model. Confirmatory factor analysis with a second split-half sample (n = 410) indicated that the parent model had poor fit indices, whereas fit of the EFA-derived models were acceptable but not uniformly ideal. Scores on the 3-factor model - which had comparatively better fit of the models tested - had adequate internal consistency and evidenced scalar invariance across gender. However, evidence of test-retest reliability after four weeks (n = 205) was poor and evidence of construct validity, assessed through correlations with additional measures included in the survey, was weak at best. Based on these results, we question the degree to which the construct of intuitive eating can be applied to nations undergoing nutrition transitions.
The Body Acceptance by Others Scale (BAOS) measures the degree to which individuals perceive body acceptance by others, but its factor structure is questionable. Here, we developed a revision of the BAOS (i.e., the BAOS-2) by designing novel items reflective of generalised perceptions of body acceptance by others. In three studies, we examined the psychometrics of the 13-item BAOS-2. Study 1, with United Kingdom adults (N = 601), led to the extraction of a unidimensional model of BAOS-2 scores and provided evidence of 4-week test-retest reliability. Study 2, with United Kingdom adults (N = 423), indicated that the unidimensional model of BAOS-2 scores had adequate fit and that scores were invariant across gender. Study 2 also provided evidence of convergent, construct, criterion, discriminant, and incremental validity. Study 3 cross-validated the fit of the unidimensional model in adults from the United State (N = 503) and provided evidence of invariance across gender and national group. Internal consistency coefficients of BAOS-2 scores were adequate across all three studies. There were no significant gender differences in BAOS-2 scores and a significant national difference had a negligible effect size. Thus, the BAOS-2 is a psychometrically-sound measure that can be utilised in future research.
The Body Appreciation Scale-2 (BAS-2) is a widely-used, 10-item measure of a core facet of positive body image. To extend its use internationally, we examined the factor structure and conducted a preliminary assessment of the psychometric properties of a novel Hebrew translation of the BAS-2. A sample of 613 Israeli adults (362 women, 251 men; age M = 29.52, SD = 9.47) completed the BAS-2 alongside demographic items and previously-validated measures of life satisfaction, self-esteem, self-compassion, and body investment. Exploratory factor analyses with a semi-random split-half subsample (n = 377) indicated that BAS-2 scores reduced to a single dimension with all 10 items. This factor structure was equivalent across women and men. Confirmatory factor analysis (CFA) with a second split-half subsample (n = 235) showed the 1-dimensional factor structure had adequate fit following one modification and multi-group CFA showed that the model was invariant across sex. Men had significantly higher BAS-2 scores than women, but the effect size was small (d = 0.22). Evidence of construct validity was demonstrated through positive associations with indices of life satisfaction, self-esteem, self-compassion, and body investment. The availability of a validated BAS-2 Hebrew translation should advance future research of body appreciation in Israel.
Science mapping is a methodology that combines quantitative analysis, classification, and visualisation to identify the composition and inter-relationships between bibliographic objects. Here, we used bibliometric science mapping to identify the overarching structure, evolution of research themes and research fronts, and geographic spread of body image research. We examined 2,783 keywords in 1,107 articles published in Body Image between 2004 and 2020, selected as being representative of body image research during this period. Co-occurrence analysis of the keywords enabled us to identify five general themes in the literature: "clinical and weight-related issues", "body image and disordered eating", "positive body image and objectification", "media effects", and "ethnicity/race". Burst analysis allowed us to identify research fronts in this research, with work on social media and positive body image in particular being identified as emergent. Finally, co-author analysis indicated that body image research networks are heavily focused on a small handful of nations, although there is evidence of a recent shift toward greater geographic spread. Our results, and the provision of interactive maps and extensive tables, should allow readers to examine connections between research clusters and areas, generate novel research ideas, and more fully understand the evolution and future trajectories of body image research.
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.
Test adaptation - the translation and validation of source instruments for use in new social identity groups - plays a vital role in body image research. Previously, Swami and Barron (2019) developed a set of good practice recommendations and reporting guidelines for the test adaptation of body image instruments. However, a number of issues in that article were not covered in depth and new issues have emerged as a result of developments in theory and practice. Here, we offer an addendum to Swami and Barron in the form of frequently asked questions. Issues discussed in this article include various methods for achieving good translations, the appropriateness of revising instrument components prior to empirical analyses, determining the number of factors to extract in exploratory factor analyses (EFA), and the usefulness of EFA versus confirmatory factor analyses (CFA) in determining factorial validity. We also cover methods of analyses that have been infrequently utilised by body image scholars, including exploratory structural equation modelling (ESEM), bifactor model analyses, and various methods for establish measurement invariance. When read as an addendum to Swami and Barron, we hope this article helps to clarify issues of importance for body image researchers interested in conducting test adaptation work.
Previous work has shown that exposure to images of nature results in elevated state body appreciation, but static images may lack ecological validity. Here, we examined the impact of exposure to short films of simulated, first-person walks in natural or built environments. Thirty-six university students completed a measure of state body appreciation before and after watching films of either a walk in a natural or a built environment created specifically for the present study. Two weeks later, they completed the same task but watched the other film type. Results indicated that exposure to the film of a natural environment resulted in significantly elevated state body appreciation (d = 0.66). There was no significant change in state body appreciation following exposure to the film of the built environment (d = 0.14). These findings suggest that exposure to films depicting the natural environment may promote immediate, moderate-sized improvements in state body image.
The present study compared the rates of negative body image and risk for disordered eating in young women who identify as part of goth subculture and a matched sample. Participants were 80 women who identified as part of goth subculture and a matched sample of 82 women from London, United Kingdom. Participants completed measures of self-ideal body size discrepancy, body appreciation, appearance investment, and eating disorder symptomatology. Between-group comparisons indicated that goth women reported significantly higher drive for thinness (d=0.51), body dissatisfaction (d=0.62), and dysfunctional appearance investment (d=0.52), as well as lower body appreciation (d=0.55), than the matched sample. Heightened expectations about appearance and self-presentation, alongside appearance competitiveness, may result in more negative body image and disordered eating in young women who identify with goth subculture, but further research is necessary on this under-studied youth subculture.
The Body Appreciation Scale-2 (BAS-2) is a measure of positive body image that has been found that have a one-dimensional factor structure in a number of different cultural groups. Here, we examined the factor structure and sex-based measurement invariance of a French translation of the BAS-2. A total of 652 university students (age M=21.33, SD=3.18) completed a newly-translated French version of the BAS-2. Exploratory factor analyses with a randomly selected split-half subsample revealed that the BAS-2 had a one-dimensional factor structure in both sexes. Confirmatory factor analyses with a second split-half subsample indicated that the one-dimensional factor structure had adequate fit following modifications and was invariant across sex. French BAS-2 scores had adequate internal consistency and men had significantly higher body appreciation than women (ds=.16-.23). These results provide preliminary support for the factorial validity of the French BAS-2.
Body image research has grown rapidly to include new cultural and linguistic populations, but this gives rise to a need for measurement instruments that are sensitive to local contextual variations while remaining equivalent across groups. Test adaptation, or the translation and validation of a source instrument for use in a new cultural group, is an important part of this process. Here, we offer an operational framework for conducting effective test adaptation. We cover good-practice guidelines for instrument translation and suggest effective strategies for achieving semantic equivalence of translated instruments. We also focus on measurement invariance and provide good-practice and reporting guidelines for conducting exploratory and confirmatory factor analyses. Finally, we suggest good-practice guidelines for demonstrating that scores on translated measures have good reliability and validity. It is our hope that the availability of this article will assist body image scholars seeking to conduct robust test adaptations of existing measurement tools.
We examined the psychometric properties of a Brazilian Portuguese translation of the Body Appreciation Scale-2 (BAS-2; Tylka & Wood-Barcalow, 2015). A sample of 990 Brazilian adults (560 women, 430 men; Mage = 31.10, SD = 8.94) completed the BAS-2 and measures of life satisfaction, self-esteem, actual-ideal weight discrepancy (women only), breast size dissatisfaction (women only), drive for muscularity (men only), and disordered eating behaviours. Exploratory factor analyses indicated that BAS-2 scores reduced to a single dimension with all 10 items in women and men. Confirmatory factor analysis supported the fit of this one-dimensional factor structure following freeing of error covariances between two pairs of items. BAS-2 scores achieved full scalar invariance across sex, and men had significantly higher BAS-2 scores than women. Internal consistency coefficients were adequate and test-retest reliability was supported up to three weeks in a subsample of 221 participants (140 women, 81 men). Evidence of construct validity was demonstrated through positive associations with indices of psychological well-being and negative associations with indices of negative body image and disordered eating behaviours. Availability of a Brazilian Portuguese translation of the BAS-2 should help to promote greater understanding of positive body image in the Brazilian context.
Previous research suggests that lower interoceptive awareness is associated with more negative body image during adolescence. However, studies have not distinguished between adaptive and maladaptive modes of attention toward interoceptive signals, and relationships between interoceptive awareness and positive body image remain unexplored. To address these issues, a sample of 265 British adolescents (140 girls, 125 boys) aged 13-16 years completed measures of interoceptive awareness, body appreciation, functionality appreciation, body pride, body shame, and body surveillance. Correlational analyses broadly indicated that greater interoceptive awareness was significantly associated with more positive body image. Multiple regressions revealed significant predictive relationships between interoceptive awareness and all facets of body image in both girls and boys, except body surveillance, which was not statistically significant for girls. At the univariate level, the interoceptive awareness facets of Attention Regulation, Body Listening, Self-Regulation, and Trusting emerged as significant predictors for at least one facet of positive body image, whilst the Noticing and Emotional Awareness facets did not. These findings broadly align with previous research with adults, which has indicated that the way interoceptive stimuli are appraised and responded to might be more closely associated with facets of body image than the tendency to notice interoceptive stimuli.
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.
Perfectionistic self-presentation refers to a desire to create an image of flawlessness in the eyes of the others and has been associated with more negative body image. We extended previous research by examining associations between perfectionistic self-presentation and breast size dissatisfaction, and also examined whether motherhood status moderated this association. A total of 484 Italian women (age M = 40.39, SD = 13.73; mothers n = 53.9%) completed measures of perfectionistic self-presentation (perfectionistic self-promotion, nondisplay of imperfection, and nondisclosure of imperfection) and breast size dissatisfaction. Preliminary analyses indicated that a majority of the sample (69.2%) reported breast size dissatisfaction, with 44.4% and 24.4% desiring larger and smaller breasts, respectively, than they currently had. Only perfectionistic self-promotion and nondisplay of imperfection were significantly correlated with breast size dissatisfaction. Both associations were additionally moderated by motherhood status, with associations being significant in non-mothers but not in mothers. Our findings suggest that motherhood may help decouple the link between perfectionistic self-presentation and breast size dissatisfaction. Future studies should assess whether this effect is due to an enhanced maternal view of breasts that emphasises nurturing and biological functions or a result of weaker investment in sociocultural norms on physical appearance.
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.
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.
The construct of intuitive eating is commonly assessed using the 23-item, 4-factor Intuitive Eating Scale-2 (IES-2; Tylka & Kroon Van Diest, 2013). In this study, we assessed the psychometric properties of a novel Greek translation of the IES-2 in adults from Cyprus. In Study 1 (N = 626), an exploratory factor analysis indicated that the IES-2 should be conceptualized as consisting of six factors that showed complete invariance across women and men. Study 2 (N = 793), using exploratory structural equation modelling (ESEM) and beifactor analysis (B-ESEM), indicated that the 6-factor B-ESEM model had adequate fit and evidenced complete invariance across sex once the correlated uniqueness of negatively worded IES-2 items was accounted for. This final model evidenced adequate composite reliability, and a global G-factor evidenced adequate convergent, concurrent, and discriminant validity. In contrast, the IES-2 S-factors showed more equivocal patterns of validity, with some S-factors showing less-than-adequate associations with body image variables, self-esteem, symptoms of disordered eating, and fruit and vegetable intake. In general, these results provide satisfactory evidence of the psychometric properties of the Greek IES-2 in adults from Cyprus, but also suggest that models of IES-2 scores may vary across national or cultural contexts.
We examined the psychometric properties of a Romanian translation of the 10-item Body Appreciation Scale-2 (BAS-2). A total of 453 university students from Romania completed the BAS-2, along with measures of disordered eating, self-esteem, satisfaction with life, and subjective happiness. In addition, a separate sample of university students (N=109) completed only the BAS-2 at two time-points three weeks apart. Principal-axis factor analysis indicated that BAS-2 scores had a one-dimensional factor structure in both women and men. Confirmatory factor analysis indicated that this factor structure had adequate fit, but invariance across sex was not supported. Further analyses indicated that BAS-2 scores evidenced internal consistency, convergent validity, and test-retest reliability in both women and men. These results suggest that BAS-2 scores reduce to one dimension in Romanian adults, but the lack of sex invariance may indicate that the same latent construct is not being measured in women and men.
The attractiveness-leniency effect (ALE) suggests that physically attractive targets are less likely to be perceived as guilty compared to less attractive targets. Here, we tested the ALE in relation to attributions of students who have committed plagiarism. British adults (N=165) were shown one of eight vignette-photograph pairings varying in target sex (female/male), physical attractiveness (high/low), and transgression severity (serious/minor), and provided attributions of guilt and severity of punishment. Analyses of variance revealed significant interactions between attractiveness and transgression severity for both dependent measures. Attractive targets were perceived as guiltier and deserving of more severe punishments in the serious transgression condition, but there was no significant difference between attractive and less attractive targets in the minor transgression condition. These results are discussed in terms of a reverse attribution bias, in which attractive individuals are judged more negatively when they fail to live up to higher standards of conduct.
