Factor structure and psychometric properties of a Bahasa Malaysia (Malay) translation of the Body Appreciation Scale-2 (BAS-2)

Validation and measurement invariance of a Korean version of the Body Appreciation Scale-2 in cisgender sexual minorities and heterosexual adults

The Body Appreciation Scale-2 (BAS-2) has been validated in various languages across samples with different characteristics. However, its validation and invariance based on sexual orientation in Korean samples have yet to be examined. The current study validated the psychometric properties of the BAS-2 in Korean sexual minorities, and examined measurement invariance between sexual minority and heterosexual individuals and between sexual minority cisgender women and men. Responses from 449 sexual minority and 400 heterosexual individuals were analyzed. In the sexual minority sample, a confirmatory factor analysis supported the scale's unidimensional structure, exhibiting strong factorial validity; further, a correlation analysis revealed positive correlations with body satisfaction, positive sexual minority identity, life satisfaction, and self-esteem, supporting the convergent and criterion-related validity. A hierarchical regression analysis confirmed the incremental validity of the BAS-2 on life satisfaction and self-esteem. The BAS-2 was invariant across women and men at the scalar level in the sexual minority sample, and across sexual minorities and heterosexuals at the partial scalar level in the total sample. Latent mean comparisons indicated no significant differences in BAS-2 scores between sexual minority women and men, while sexual minorities scored significantly lower than heterosexuals. The multiple-indicators multiple-causes model provided evidence of differential item functioning.

The validity of the Czech version of Body Appreciation Scale-2 for adolescents

BACKGROUND

Understanding the formation of body image is critical for the prevention and treatment of eating disorders, especially in adolescence, when body image develops significantly. One of the important facets of body image is body appreciation, which consists of positive feelings and attitudes towards the body regardless of its perceived "flaws". To measure body appreciation, Body Appreciation Scale-2 (Tylka and Wood-Barcalow in Body Image 12:53-67, 2015a), a unidimensional 10-item measure, has been developed and routinely used in body image research. The current study examined the validity (i.e., factor structure, gender and age invariance, associations with other constructs) of the Czech version of Body Appreciation Scale-2 for adolescents.

METHODS

The study used two large samples of Czech adolescents, aged 13-18 (N1 = 613, M = 15.5, 52% girls; N2 = 1,530, M = 15.4, 50% girls). The data were collected in August 2021 (N1) and November 2020 (N2) through an online survey. For the data analysis, we used confirmatory factor analysis (CFA), multi-group confirmatory factor analysis (MG-CFA), and Structural Equation Modeling (SEM).

RESULTS

Our findings supported the proposed unidimensional factor structure and the gender (i.e., girls, boys) and age (i.e., 13-15, 16-18) scalar invariance of the Czech version of Body Appreciation Scale-2. The data also showed the expected positive correlations with body satisfaction and self-esteem, and negative correlations with media-ideal internalization, appearance schematicity, and depression. Furthermore, we discovered that body appreciation was more strongly connected to media-ideal internalization and depression for girls than boys.

CONCLUSIONS

The present study provided robust evidence that supports the validity of the Czech version of Body Appreciation Scale-2 and its usability for the assessment of body appreciation in Czech adolescents. We also proposed future directions for the research on body appreciation based on the explored gender differences.

Psychometric properties of an Arabic translation of the body appreciation scale (BAS-2) and its short forms (BAS-2SF) in a community sample of Lebanese adults

OBJECTIVES

The present study sought to examine the factor structure, reliability, validity and gender invariance of the Arabic Body Appreciation Scale (BAS-2), and its two short forms (the 3-item and 2-item BAS-2SF) among community Lebanese Arabic-speaking adults.

METHODS

We carried-out an online cross-sectional survey. The 10-item BAS-2, the functionality appreciation scale and the Eating Attitudes Test-26 were completed by 826 Lebanese community adults (57.9% females, aged 25.42 ± 8.44 years).

RESULTS

The Arabic 10-item, 3-item and 2-item BAS-2 converged on a one-factor solution, and demonstrated high internal consistency (McDonald's ω value of .92, .88, and .86 respectively). All indices suggested that configural, metric, and scalar invariance was supported across gender. The 3-item and 2-item BAS-2SF were highly correlated with the original BAS-2 (r > 0.9). Higher 10-item, 3-item and 2-item BAS-2 scores correlated significantly and strongly with more positive eating attitudes and greater functionality appreciation, and higher 10-item BAS-2 scores correlated positively and weakly with BMI, supporting convergent validity.

CONCLUSION

The present work contributes to the literature by providing a psychometrically sound Arabic-translation of the BAS-2 and short-forms, benefitting both researchers and clinicians.

Body appreciation around the world: Measurement invariance of the Body Appreciation Scale-2 (BAS-2) across 65 nations, 40 languages, gender identities, and age

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.

Further evaluation of the psychometric properties of the German version of the Body Appreciation Scale-2 (BAS-2): Cross-validation, measurement invariance, and population-based norms

Using a representative sample of the German general population (N = 2509, 16-74 years), this work aimed to cross-validate the modified one-factor model recently reported for the German Body Appreciation Scale 2 (BAS-2). We also examined measurement invariance across gender, tested differential item functioning across age and BMI, systematically evaluated subgroup differences, and provided norms according to subgroups. Overall, the BAS-2 demonstrates good internal consistency. Cross-validation supported the generalizability of the modified one-factor model. Multi-group confirmatory factor analyses supported full scalar invariance across gender; comparisons revealed higher scores among men compared to women with a small effect size. Age (only women) and BMI (both genders) significantly predicted latent BAS-2 scores. Of note, differential item functioning for age and BMI was observed. Concerning manifest group differences, we found a significant main effect of weight status: Individuals with obesity reported the lowest body appreciation levels, while individuals with underweight/ normal weight reported highest levels. Our findings suggest that the German BAS-2 has good psychometric properties and is suitable for examining body appreciation across gender among German women and men. Moreover, norm values enable future usage of the scale in health and clinical research by providing reference data for interpretation.

Measurement accuracy and reliability of self-reported versus measured weight and height among adults in Malaysia: Findings from a nationwide blood pressure screening programme

Most studies reporting prevalence of obesity use actual weight and height measurements. Self-reported weight and height have been used in epidemiological studies as they have been shown to be reliable, convenient, and inexpensive alternatives to actual measurements. However, the accuracy of self-reported weight and height might vary in different regions because of the difference in health awareness and social influences. This study aims to determine the accuracy and reliability of self-reported weight and height compared to actual measured weight and height among adults in Malaysia. This was a cross-sectional study conducted at the community level during blood pressure screening campaigns. Participants self-reported their weight and height in a questionnaire survey. Their weight and height were validated using measurements by researchers on the same setting. Body mass index (BMI) was defined as underweight (<18.5kg/m2), normal (18.5-22.9 kg/m2), overweight (23-27.4 kg/m2) and obesity (≥27.5 kg/m2). Bland-Altman analysis, intraclass correlation coefficients and weighted Kappa statistics were used to assess the degree of agreement between self-reported and measured weight and height. A total of 2781 participants were recruited in this study. The difference between the mean self-reported and measured weight and height were 0.4 kg and 0.4 cm respectively. Weighted Kappa statistics analysis showed that there was a substantial agreement between the BMI classifications derived from self-reported and actual measurement (ҡ = 0.920, p<0.001). There was no marked difference in the sensitivity and specificity of self-reported BMI among Malaysian adults by gender. We observed substantial agreement between self-reported and measured body weight and height within a sample of Malaysian adults. While self-reported body weight showed weaker agreement with actual measurements particularly for obese and overweight individuals, BMI values derived from self-reported weight and height were accurate for 88.53% of the participants. We thus conclude that self-reported height and weight measures may be useful for tracking and estimating population trends amongst Malaysian adults.

Rural-urban differences in body appreciation and associations with life satisfaction in adults from Sabah, Malaysia

Studies of body appreciation have typically focused on measurement of the construct in urban populations and there remains very little research on body appreciation in rural communities. To fill this gap, the present study examined rural-urban differences in body appreciation in an adult Kadazan-Dusun sample from the state of Sabah in Malaysia. Participants from rural (n = 215) and urban (n = 219) locales in the West Coast administrative district of Sabah were asked to complete Malay versions of the Body Appreciation Scale-2 (BAS-2) and the Satisfaction With Life Scale, and to provide their demographic details. Multi-group confirmatory factor analysis evidenced both partial metric invariance (by allowing loadings for three items to vary) and partial scalar invariance (by freeing the intercept for one item) on the BAS-2. Between-group analyses indicated that rural participants had significantly greater body appreciation than urban participants overall. Additionally, urban men had significantly greater body appreciation than urban women, but there was no gender difference in the rural subsample. Finally, correlational analyses indicated that body appreciation was significantly associated with life satisfaction in both the rural and urban subsamples. The present results highlight the importance of further considering the phenomenology of body appreciation in rural communities.

Enriching sociocultural perspectives on the effects of idealized body norms: Integrating shame, positive body image, and self-compassion

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

Portuguese version of the Body Appreciation Scale-2 for Children (BAS-2C): Psychometric evaluation and measurement of invariance across sex

Body appreciation, a central aspect of positive body image, recently started to capture the attention of the scientific community as a potential determinant of well-being. However, little is known about onset and early identification in both males and females, as studies on this subject in childhood are still scarce, due in part to a dearth of validated instruments. Therefore, the main purpose of this study is to examine the psychometric properties and sex invariance of a Portuguese version of the Body Appreciation Scale-2 for Children (BAS-2C; Halliwell et al., 2017). We also explored the relationship between the BAS-2C and body mass index z-scores (BMIz). Participants were 328 children, ages 9-to-11 years (50.9% girls). Confirmatory factor analysis indicated that the one-dimensional factor structure had adequate fit, but sex invariance was not supported. Differential item functioning analysis revealed that boys and girls respond differently to item #9, which assesses body comfort. BAS-2C scores evidenced internal consistency and convergent validity with quality of life, healthy eating habits, and body size dissatisfaction. BMIz showed a low ability to predict body appreciation. This study brings support for the use of the BAS-2C in Portuguese-speaking children, but caution is warranted in comparing BAS-2C scores across sexes.

Factor structure and psychometric properties of a Korean translation of the Body Appreciation Scale-2

The applicability of the Body Appreciation Scale-2 (BAS-2) in a Korean context is still unexplored, even though awareness of the importance of a positive body image has increased in South Korea. The current study examined the factor structure and psychometric properties of a Korean translation of the BAS-2, specifically to (1) translate and culturally adapt the BAS-2 to Korea, (2) confirm its unidimensional construct, and (3) identify its associations with body image and psychological outcomes across sex with a Korean sample. Data from 839 Korean adult men (n = 415) and women (n = 424) were randomly split into two subsamples. Using the exploratory factor analysis to confirmatory factor analysis strategy, the current study showed support for one factor structure of a Korean translation of the BAS-2. Scalar measurement invariance was found between men and women. Further analyses revealed construct validity through associations with measures of muscularity and body fat dissatisfaction (for men), internalization (for women), and appearance evaluation, as well as incremental validity through hierarchical regression analyses predicting life satisfaction and self-esteem. The Korean BAS-2 presented good internal consistency and test-retest reliability. The Korean BAS-2 is a reliable and valid measure, allowing for cross-cultural comparisons of body appreciation.

Factor structure and psychometric properties of the Body Appreciation Scale-2 among Brazilian cisgender gay and bisexual men

Positive body image may be particularly relevant to assess for Brazilian gay and bisexual men, given the extent of sexual minority stressors (e.g., harassment, discrimination) in Brazilian culture, which can impair one's self-perception and concept. Thus, the purpose of the present study was to assess the psychometric properties of the Body Appreciation Scale-2 (BAS-2) among Brazilian cisgender gay and bisexual adult men, aged 18-50 years. We evaluated the factor structure using a two-step, split-sample exploratory (EFA; n = 682) and confirmatory factor analytic approach (CFA; n = 727), which supported the one-factor structure of the measure. Additionally, convergent validity, internal consistency, and 2-week test-retest reliability were assessed. The BAS-2 scores showed small to large negative correlations with self-objectification beliefs and behaviors, drive for muscularity and appearance-ideal internalization measures. We also found good internal consistency and test-retest reliability of the measure. Taken together, these results support the use of the BAS-2 in Brazilian cisgender gay and bisexual men and provide an initial understanding of body appreciation and other related constructs among this population.

Psychometric properties of a Mandarin Chinese version of the Body Appreciation Scale-2 with residents from Chinese mainland

The current study aimed to translate the Body Appreciation Scale-2 (BAS-2) into Mandarin Chinese and explore its psychometric properties with college students from the Chinese mainland. In Study 1 (N = 840, 415 women, 425 men), an exploratory factor analysis upheld the unidimensional factor structure of the Mandarin Chinese BAS-2, and McDonald's omega supported the internal consistency reliability of its scores. Evidence of construct validity of the Mandarin Chinese BAS-2 was also accrued via its positive correlations with self-esteem, self-compassion, and body satisfaction as well as negative correlations with BMI, weight discrepancy, negative affect, and body surveillance. Its negative correlation with eating disorder symptomatology and negligible correlation with impression management supported its criterion-related validity and discriminant validity, respectively. Additionally, the Mandarin Chinese BAS-2 contributed unique variance in eating disorder symptomatology and self-esteem beyond the variance explained by BMI and other body satisfaction measures, providing evidence of incremental validity. Study 2 (N = 522, 322 women, 230 men) confirmed its unidimensional factor structure, upheld the internal consistency and stability of its scores over a 3-month period, and supported its measurement invariance between women and men. Taken together, these findings support the cross-cultural validity of the Mandarin Chinese BAS-2 on the Chinse mainland.

Validation of a German version of the Body Appreciation Scale-2 (BAS-2)

The Body Appreciation Scale-2 (BAS-2) is the most current measure of body appreciation, a central facet of positive body image. This work aimed to examine the factor structure and psychometric properties of a German version. In Study 1 (N = 659; M_age = 27.19, SD = 8.57), exploratory factor analysis (EFA) revealed that the German BAS-2 has a one-dimensional factor structure in women and men, showing cross-gender factor similarity. In Study 2 (N = 472; M_age = 30.08, SD = 12.35), confirmatory factor analysis (CFA) further supported the original scale's one-dimensional factor structure after freeing correlated errors. The German BAS-2 also showed partial scalar invariance across gender, with women and men not differing significantly in latent mean scores. As predicted, we found convergent relationships with measures of self-esteem, intuitive eating, and variables associated with negative body image (i.e., weight- and shape concerns, drive for thinness). Correlations with BMI were small and in an inverse direction. Incremental validity was demonstrated by predicting self-esteem and intuitive eating over and above measures of negative body image. Additionally, the German BAS-2 showed internal consistency and 2-week test-retest reliability. Overall, our results suggest that the German BAS-2 is a psychometrically sound instrument.

Short forms of the Body Appreciation Scale-2 (BAS-2SF): Item selection and psychometric evaluation

The 10-item Body Appreciation Scale-2 (BAS-2; Tylka & Wood-Barcalow, 2015) is a widely used contemporary measure of positive body image that assesses one's love for, acceptance and appreciation of, and respect for their body. Given the need for abbreviated measures to reduce participant burden and study cost, we aimed to generate a short form of the BAS-2 (BAS-2SF). Two versions of the BAS-2SF emerged: a 3-item version derived deductively from theory (items selected based on their unique contribution to the body appreciation construct), and a 2-item version generated empirically (items selected based on a genetic algorithm approach). Psychometric evidence was garnered across five studies, totaling 3114 participants. Both BAS-2SF versions correlated highly (rs = .93-.97) with the original 10-item BAS-2 and demonstrated internally consistent and stable scores. Factor analyses revealed high item-factor loadings, unidimensionality, and gender invariance of the 3-item BAS-2SF. Correlations with construct validity measures, as well as model pathways, were similar between both BAS-2SF versions and the 10-item BAS-2. BAS-2SF versions also evidenced incremental validity. Both BAS-2SF versions retain the psychometric integrity of the BAS-2 and are recommended for use; however, the 3-item BAS-2SF is an ideal option for researchers who wish to estimate a body appreciation latent factor.

The impact of nature exposure on body image and happiness: an experience sampling study

Exposure to nature is associated with improved psychological well-being and positive body image. Here, we examined whether everyday exposure to natural environments is associated with state body image outcomes (and, for comparative reasons, state happiness) using an experience sampling method. One-hundred-and-seven participants completed a 30-day experience sampling phase in which they reported their state body image (body weight, body shape, and physical appearance satisfaction), state happiness, and features of the surrounding environment (total = 6,025 responses) at three random time-points each day. Results indicated that being outdoors was associated with significantly higher state body image on all three indicators, but effect sizes were lower compared to effects on state happiness. Specific environment type was also important, with blue-spaces and wood- and grasslands, respectively, having stronger effects than other environments. These results provide evidence that everyday exposure to natural environments is associated with more positive state body image and greater happiness.

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.

Psychometric properties of a Bahasa Malaysia (Malay) translation of the Body and Appearance Self-Conscious Emotions Scale (BASES): An assessment using exploratory structural equation modelling

The Body and Appearance Self-Conscious Emotions Scale (BASES) measures self-conscious emotions in relation to the body and appearance. While scores have been shown to support a hypothesised 4-factor model consisting of facets of shame, guilt, authentic pride, and hubristic pride, previous studies are limited in their sole reliance on confirmatory factor analysis. Here, we assessed the psychometric properties of a novel Bahasa Malaysia translation of the BASES using an exploratory structural equation modelling (ESEM) framework. Malaysian adults (N = 1049) completed the BASES along with measures of body appreciation, psychological well-being, and secure non-striving. The results of exploratory factor analysis and ESEM in separate split-half subsamples supported a 2-dimensional model consisting of Shame-Guilt and Authentic-Hubristic Pride. This 2-dimensional model was broadly invariant across ethnicity, gender, and age, had adequate internal consistency, and evidenced adequate construct validity in relation to the Authenthic-Hubristic Pride subscale. We interpret our findings as consistent with the view that cultural factors shape the way in which body and appearance-related self-conscious emotions are manifested. Our results also highlight the importance of considering alternative conceptualisations of body and appearance-related self-conscious emotions, which previous studies may have obscured through their reliance on confirmatory factor analyses.

Validation and Measurement Invariance of the Body Appreciation Scale-2 between Genders in a Malaysian Sample

The 10-item Body Appreciation Scale-2 (BAS-2) is a measurement for individuals to self-report the extent to which they accept and respect their bodies. Although the BAS-2 has been translated into the Malay language and found to have promising qualities, the psychometric characteristics of the English version of BAS-2 remain unknown in the Malaysian context. The present study thus administered the English version BAS-2 and selfie-editing frequency scale to 797 individuals aged 18 to 56 years old in Malaysia. The dataset that was randomly divided into two halves were submitted to exploratory factor analysis and confirmatory factor analysis respectively. Both of the factor analyses consistently support a one-factor model. The Cronbach's alpha and McDonald omega coefficients were greater than 0.90, indicating that the BAS-2 has good internal consistency. The incremental validity is also evident. A hierarchical multiple regression showed that the BAS-2 score had a positive relationship with selfie-editing frequency after controlling for age and gender. Moreover, the measurement invariance test supported scalar invariance between genders, and an analysis of covariance did not find significant gender differences. Overall, the findings replicate past findings and regularly support the usability of the BAS-2 in the Malaysian context. The implications of the BAS-2 and future directions are also discussed.

Science mapping research on body image: A bibliometric review of publications in Body Image, 2004-2020

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 Body Acceptance by Others Scale-2 (BAOS-2): Psychometric properties of a Bahasa Malaysia (Malay) translation and an assessment of invariance across Malaysia, the United Kingdom, and the United States

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.

Translation and validation of an Italian version of the Body Appreciation Scale-2

Body appreciation is considered a key dimension of positive body image. Tylka and Wood-Barcalow (2015) developed the Body Appreciation Scale-2 (BAS-2), a psychometrically sound measure to assess body appreciation. The present study examines various psychometric properties (i.e. factor structure, sex-based measurement invariance, and construct validity) of an Italian translation of the BAS-2 in a community sample (N = 601; F = 50.6 %; M_age = 25.72; SD = 4.81). Exploratory factor analyses with a randomly selected split-half subsample (n = 300; F = 50 %) supported the one-dimensional factor structure among both sexes. Confirmatory factor analyses with a second split-half subsample (n = 301; F = 51.16 %) indicated that the one-dimensional factor structure had adequate fit after some modifications were made. BAS-2 scores achieved full invariance across sex and men reported significantly higher scores than women (d = 0.45). Further, the Italian version of the BAS-2 had good internal consistency and was positively correlated with self-esteem and life satisfaction, whereas negative associations were found with body dissatisfaction and eating disorder symptoms. Results indicated that the Italian BAS-2 has good psychometric properties.

Cross-validation of the body appreciation scale-2: invariance across sex, body mass index, and age in Mexican adolescents

Cross-validation is a useful strategy to address problems associated with the post hoc model fitting. The aim of this study was to cross-validate the BAS-2, in two samples (Calibration and Validation Samples), using an invariance testing strategy. 1127 Mexican adolescents (508 males and 619 females), aged 11-19 years (M = 15.41, SD = 2.30), allocated in two samples (n₁ = 672; n₂ = 455) completed the Mexican version of the BAS-2, along with other body image-related instruments. The cross-validation supported the generalizability of the one-factor respecified model of the BAS-2. The measure was invariant across body mass index and age, but not across sex. Internal consistency and test-retest reliability (a three-week period between each test) was excellent. In support of the validity of the BAS-2, it was positively associated with scores on body esteem, but negatively with body mass index, drive for thinness, and body dissatisfaction. Normal-weight and young adolescents groups showed higher body appreciation than excess-weight and late adolescents groups, respectively. Considering these findings, it is reasonable to conclude that the BAS-2 is a reliable and valid instrument to assess body appreciation in Mexican adolescents. LEVEL OF EVIDENCE: Level V, cross-sectional, descriptive study.

Cross-cultural adaptation of body image assessment instruments for university students: a systematic review

The theoretical-methodological process of cross-cultural adaptation of scales is fundamental for the expansion of research possibilities related to a given area and population, as instrument adequacy allows for the consistent assessment of the construct being studied. This article aims to highlight the different theoretical-methodological processes of cross-cultural adaptations of scales for assessing body image among young university students. The articles were selected in February 2020, with the following search descriptors: ("body image") and (young or "college students" or graduating or graduat *) and ("cross-cultural validation" or "cross-cultural adaptation"), in three databases-Scopus, PsycINFO, and Web of Science, without any time restrictions. Altogether, 304 studies were surveyed on the different bases mentioned above, and 14 studies published between 2010 and 2019 were evaluated. This study highlighted the methodological procedures used in the process of cross-cultural adaptation, as well as the population, the types of validity and reliability, and also the main limitations, strengths, and results reported in each study included in this review. The information presented in this review will allow new researchers to make more appropriate choices about instruments for assessing body image in young university students, in addition to presenting the methodological evolution on this theme.

Assessing positive body image, body satisfaction, weight bias, and appearance comparison in emerging adults: A cross-validation study across eight countries

Positive body image refers to individuals' ability to conceptualize their bodies with love, respect, and appreciation. The study of positive body image is relatively new, and instruments used to investigate this multi-faceted construct have received limited use in non-English speaking countries. Thus, the aim of this investigation is to consider four measures that are associated with positive body image across eight different countries. Participants (n = 6272) completed the Body Appreciation Scale-2, the Body Areas Satisfaction Scale, the Physical Appearance Comparison Scale, and the Weight Bias Internalization Scale. Multi-group confirmatory factor analyses (MG-CFAs) and item-response theory (IRT) models were used to examine the measurement invariance of these surveys. Our results generally suggest that positive body image, weight bias, and appearance comparison can be assessed using brief assessments and that these four instruments can be used in different countries, but care should be taken to consider individuals' gender, BMI, and socio-economic position.

The association between body appreciation and body mass index among males and females: A meta-analysis

To date, a number of studies have reported an association between body appreciation and body mass index (BMI), but the findings are not consistent. Using a meta-analytic approach, the current study aimed to clarify this association as well as to explore what factors might have contributed to the inconsistency across previous studies. By searching and screening potential studies published up to June 2019 in four databases, we identified 26 articles that reported an association between body appreciation and BMI among males, and 59 articles among females. Under a random-effects model, among males the overall estimate of the association between body appreciation and BMI was negative and small, with the pooled r = -.20 (95 % CI: -.25, -.14) and an adjusted (for publication bias) pooled r = -.11 (95 % CI: -.16, -.06). Among females, the overall estimate of the association was negative and small (but close to moderate), with r = -.27 (95 % CI: -.30, -.24). A mixed-effects model identified several moderators that contributed to the inconsistency across previous studies. These results indicate that the overall negative association between body appreciation and BMI is weak among males, and slightly larger among females. Potential explanations, implications, and future research directions are discussed.

An examination of the factor structure and preliminary assessment of the psychometric properties of a Hebrew translation of the Body Appreciation Scale-2 (BAS-2)

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.

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.

Cross-cultural measurement invariance of the Body Appreciation Scale-2 across five countries

The Body Appreciation Scale-2 (BAS-2; Tylka & Wood-Barcalow, 2015a, 2015b) is a widely used measure of positive body image within many cultures and countries; yet, cross-cultural examinations are few. The present study aimed to investigate the measurement invariance of the BAS-2 across adults from five countries: Iran, Japan, Poland, Serbia, and the U.S. The sample included 2944 participants ranging in age from 18 to 82 years. The findings provided evidence that the BAS-2's one-dimensional structure is the same in these countries. Partial metric invariance (when some but not all items contribute to a latent construct equally for groups) indicated that nine out of 10 items contributed to the latent body appreciation construct to a similar degree across the countries. When a Multiple Indicators Multiple Causes (MIMIC) model was applied with participants' age and gender as covariates, evidence of differential item functioning was found. Results suggest that both age and gender influenced body appreciation, indicating that the body appreciation factor means are different at different levels of the covariates. In conclusion, cross-culturally body appreciation may be shaped by country, language, age, and gender correlates to different degrees. In future research, measurement invariance analyses should be conducted prior to cultural group comparisons on the BAS-2.

Psychometric properties of the Japanese version of the Body Appreciation Scale-2 for Children (BAS-2C)

Despite the heightened interest in positive body image research in recent years, few studies have explored positive body image among children. Examining the Body Appreciation Scale-2 for Children (BAS-2C) using a different cultural sample than the original version would thus be beneficial in extending the research on this topic. This research aimed to validate the BAS-2C for use in Japan. The measures were administered to 243 children, and the participants completed the survey in their classrooms with the support of a teacher. The survey was repeated after four weeks. Confirmatory factor analysis showed that the one-factor structure was the same as that of the original version, and the BAS-2C was invariant across gender. Scores on the BAS-2C demonstrated good internal consistency and test-retest reliability over a four-week period. In addition, construct validity was accrued through the BAS-2C's correlation with body dissatisfaction (among girls), self-esteem, and life satisfaction. Results indicated that the BAS-2C shows good psychometric properties among Japanese children, and supports further research into positive body image in this group.

Meta-analysis of gender differences in body appreciation

There are a number of studies that have conducted comparisons of body appreciation between males and females. However, findings are largely inconsistent, making it unclear whether there are actual gender differences in body appreciation. With a meta-analytic approach, the current study quantitatively reviewed and synthesized previous findings, published up to May 2019, on gender differences in body appreciation. After searching and screening potential studies in four databases (i.e., PubMed, PsycINFO, Web of Science, and ProQuest Dissertations & Theses Global), we identified 40 relevant articles published from 2008 to 2019. A random-effects model reveals an overall estimate of gender difference in body appreciation of d = 0.27 (95 % CI: 0.21, 0.33; p <  .001); that is, males generally have a higher level of body appreciation than females, with a small effect size. Survey method, type of sample (cohorts), and age were identified as significant moderators that have contributed to the variability in previous findings. Future research and interventions in body appreciation may consider gender differences in their designs.

Associations between Body Appreciation and Disordered Eating in a Large Sample of Adolescents

Body appreciation is one of the main facets of a positive body image. The present study aimed to examine the psychometric properties of the Lithuanian version of the Body Appreciation Scale-2 (BAS-2-LT) and test the associations between body appreciation and disordered eating in a large sample of adolescents of both genders. Method: The sample consisted of 1412 adolescents (40.2% were boys). The ages ranged from 15 to 18 years (92.4% were 17), with a mean age of 16.9 (SD = 0.5) for girls and 17.0 (SD = 0.4) for boys. Participants completed the BAS-2-LT alongside the measures of body dissatisfaction, disordered eating, body mass index, self-esteem, body functionality, and participation in sports. Linear regressions were used to test the associations between study variables and disordered eating. Results: BAS-2-LT replicated the original one-dimensional structure in girls and boys. Invariance across genders was established. The instrument showed good internal consistency and temporal stability. Body appreciation was negatively correlated with higher levels of body mass index, body dissatisfaction, and disordered eating. Positive associations were observed between body appreciation, self-esteem, body functionality, and sports participation. Higher levels of body appreciation decreased the risk of disordered eating behaviors in both genders. Conclusions: The results of the present study support the psychometric properties of BAS-2-LT. Body appreciation is associated with lower disordered eating in adolescent girls and boys. These findings present empirical support for the development of interventions programs that promote positive body images and aim to prevent disordered eating in adolescent boys and girls.

Assessing the measurement invariance of a Latin-American Spanish translation of the Body Appreciation Scale-2 in Mexican, Argentinean, and Colombian adolescents

In order to advance in the study of positive body image among different cultures, it is important to create culturally appropriate measures. We examined the psychometric properties of a Latin-American Spanish translation of the Body Appreciation Scale-2 (BAS-2; Tylka & Wood-Barcalow, 2015a), specifically assessing measurement invariance using a large sample of 3845 male and female adolescents from Argentina, Mexico, and Colombia. Participants completed the BAS-2, Eating Disorder Inventory-2, Male Body Attitude Scale and the Sociocultural Attitudes Toward Appearance Questionnaire-3. The BAS-2 had a unidimensional factor structure in each of the three samples. We confirmed the structural, metric, and scalar invariance of the scale regardless of gender or country. Adolescents in Argentina had lower body appreciation compared with those in Mexico and Colombia. Overall, females had lower body appreciation than males, with the greatest gender difference found in the Argentinean sample. Our findings strongly support the validity and reliability of this Latin-American translation of the BAS-2 in measuring positive body image in adolescents in Argentina, Mexico, and Colombia.

Dimensional structure, psychometric properties, and sex and ethnic invariance of a Bahasa Malaysia (Malay) translation of the Intuitive Eating Scale-2 (IES-2)

The Intuitive Eating Scale-2 (IES-2; Tylka & Kroon Van Diest, 2013) is a widely-used measure of facets of intuitive eating. We examined the psychometric properties of a Bahasa Malaysia (Malay) translation of the IES-2 in a sample of Malaysian Malay and Chinese adults (N = 921). Participants completed a Malay translation of the IES-2 along with demographic items and measures of psychological well-being, positive and negative body image, and internalisation of appearance ideals. Exploratory factor analyses (EFAs) with Malay subsamples indicated that IES-2 scores reduced to 4 factors in women and 3 in men, both of which diverged from the parent model. Confirmatory factor analysis failed to confirm the parent 4-factor model, and indices for the EFA-derived models were acceptable but not ideal. Of the models tested, the EFA-derived 3-factor model had the best fit indices. Scores on this model had adequate internal consistency and were invariant across sex and ethnicity, but between-group differences in subscale scores were non-significant or negligible. Evidence of the construct validity of Malay IES-2 scores was mixed, particularly in men. These results lead us to question the degree to which intuitive eating as a construct is applicable to Malaysian populations specifically and non-Western populations generally.

Validation of the Body Appreciation Scale-2 and relationships to eating behaviors and health among sexual minorities

Although the study of positive body image continues to expand, researchers have predominantly focused the study of this newer construct among presumed heterosexual participants. The purpose of the present study was to examine the factor structure of a measure of positive body image, the Body Appreciation Scale-2 (BAS-2), among sexual minority participants. The present study also sought to psychometrically validate the BAS-2 among sexual minorities by assessing its relationship with other facets of positive body image, including functionality appreciation and body image flexibility, as well as other related constructs, such as body dissatisfaction, disordered eating behaviors, intuitive eating behaviors, and physical and mental health. Results from a confirmatory factor analysis of 223 sexual minority adults (M_age = 32.45, SD = 10.07) indicated that the BAS-2 displayed strong factorial validity with a unitary factor structure. Furthermore, the BAS-2's construct validity was supported based on correlations with other measures of positive body image, body dissatisfaction, and disordered eating behavior. Results from this cross-sectional study supported a relationship between body appreciation and intuitive eating behaviors, as well as physical and mental health among sexual minority participants. These findings provide an initial understanding of body appreciation and other related constructs among sexual minority individuals.

Translation and validation of a Brazilian Portuguese version of the Body Appreciation Scale-2 in Brazilian adults

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; M_age = 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.

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.

Dimensional structure, psychometric properties, and sex invariance of a Bahasa Malaysia (Malay) translation of the Multidimensional Body-Self Relations Questionnaire-Appearance Scales (MBSRQ-AS) in Malaysian Malay adults

The 34-item Multidimensional Body-Self Relations Questionnaire-Appearance Scales (MBSRQ-AS) is a widely-used measure of multidimensional body image. Here, we examined the psychometric properties of a Bahasa Malaysia (Malay) translation of the MBSRQ-AS. A sample of 629 Malaysian Malays (women n = 315) completed the MBSRQ-AS, as well as measures of body appreciation, psychological well-being, perceptions of appearance ideals, and internalisation of appearance ideals. Exploratory factor analysis indicated that the MBSRQ-AS items reduced to four dimensions, although one factor had less-than-adequate internal consistency. Omitting this factor resulted in a 23-item 3-factor solution, which we tested for fit using confirmatory factor analysis (CFA) alongside the parent 5-factor model. CFA indicated that both models had good fit on some indices, but less-than-ideal fit on other indices, with the 3-factor model showing comparatively better fit. Multi-group CFA indicated that it was not possible to achieve scalar invariance across sex, but internal consistency coefficients were adequate. Evidence of construct validity, as assessed through correlations between MBSRQ-AS scores and additional measures, was mixed. We discuss reasons that complicate interpretation of the dimensionality of MBSRQ-AS scores in this and previous studies, and call for further research on this issue.
