Existing measures of women's breasted experiences have focused on negative experiences, which de-centres women's meaning-making and relationships with their breasts. To rectify this, we developed a novel measure of women's positive breasted experiences, the Breast Appreciation Scale (BrAS), and examined the psychometric properties of this novel measure across four studies. Study 1, with 307 United Kingdom women, led to the extraction of a 9-item, unidimensional model of BrAS scores that showed adequate composite reliability and 4-week test-retest reliability. Study 2, with 297 United Kingdom women, showed that the unidimensional model of BrAS scores had adequate fit and evidenced convergent, concurrent, discriminant, and incremental validity. Study 3, with 295 women from the United Kingdom, provided additional support for factorial validity and concurrent validity, and additionally provided evidence of known-groups validity insofar as mothers had greater breast appreciation than non-mothers. Study 4 showed that the BrAS was scalar invariant across women from Australia, the United Kingdom, and the United States (N = 573) and provided additional evidence of concurrent validity. Based on these results, we conclude that the BrAS is a psychometrically valid measure of women's positive breasted experiences that can be utilised in future research.
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 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 Acceptance by Others Scale-2 (BAOS-2) is a 13-item instrument measuring generalised perceptions of body acceptance by others. Here, we first demonstrate that a Bahasa Malaysia (Malay) translation of the BAOS-2 is psychometrically valid in a sample of 1,049 Malaysian adults (Study 1). Using exploratory and confirmatory factor analysis, we extracted a unidimensional model of BAOS-2 scores that retained all 13 items. BAOS-2 scores had adequate internal consistency and indices of validity (convergent, construct, concurrent, and incremental), and were scalar invariant across gender and ethnicity (Malaysian Malays vs. Chinese). Next, we assessed invariance of BAOS-2 scores across samples from Malaysia, the United Kingdom, and the United States (total N = 2,575; Study 2). Multi-group confirmatory factor analysis showed that partial scalar invariance was achieved. Participants in the interdependent cultural context of Malaysia had significantly higher scores - with small effect sizes - than their counterparts in the independent contexts of the United Kingdom and United States. In addition, women had significantly higher scores than men, but the effect size was negligible. The present study indicates that the Malay BAOS-2 is a psychometrically valid instrument and presents the first comparison of BAOS-2 scores across interdependent and independent contexts.
White supremacy and racial inequities have long pervaded psychological research, including body image scholarship and practice. The experiences of white, heterosexual, able-bodied, cisgender (predominantly college) women from wealthy, Westernized nations have been centered throughout body image research and practice, thereby perpetuating myths of invulnerability among racialized groups and casting white ideals and experiences as the standard by which marginalized bodies are compared. Body image is shaped by multiple axes of oppression that exist within systemic and structural systems, ultimately privileging certain bodies above others. In this position paper, we highlight how white supremacy has shaped body image research and practice. In doing so, we first review the history of body image research and explain how participant sampling, measurement, interpretive frameworks, and dissemination of research have upheld and reinforced white supremacy. Next, grounded in inclusivity and intersectionality, we advance the Sociostructural-Intersectional Body Image (SIBI) framework to more fully understand the body image experiences of those with racialized and minoritized bodies, while challenging and seeking to upend white supremacy in body image research and practice. We encourage other scholars to utilize the SIBI framework to better understand body inequities and the body image experiences of all people, in all bodies.
The Body Appreciation Scale-2 (BAS-2) is a widely used measure of a core facet of the positive body image construct. However, extant research concerning measurement invariance of the BAS-2 across a large number of nations remains limited. Here, we utilised the Body Image in Nature (BINS) dataset - with data collected between 2020 and 2022 - to assess measurement invariance of the BAS-2 across 65 nations, 40 languages, gender identities, and age groups. Multi-group confirmatory factor analysis indicated that full scalar invariance was upheld across all nations, languages, gender identities, and age groups, suggesting that the unidimensional BAS-2 model has widespread applicability. There were large differences across nations and languages in latent body appreciation, while differences across gender identities and age groups were negligible-to-small. Additionally, greater body appreciation was significantly associated with higher life satisfaction, being single (versus being married or in a committed relationship), and greater rurality (versus urbanicity). Across a subset of nations where nation-level data were available, greater body appreciation was also significantly associated with greater cultural distance from the United States and greater relative income inequality. These findings suggest that the BAS-2 likely captures a near-universal conceptualisation of the body appreciation construct, which should facilitate further cross-cultural research.
