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.

Brazilian Portuguese Version of the Amputee Body Image Scale: Cultural Adaptation and a Psychometric Analysis

Body image adjustments after a limb loss are essential to rehabilitation. This study evaluated the psychometric properties of the Brazilian Portuguese version of the Amputee Body Image Scale (ABIS). We analyzed data from a nonprobability sample of 100 participants (71% men, mean age 48.26 ± 18.35 years) by using a confirmatory factor analysis with partial least square path modeling. We evaluated the structural model by using Pearson's coefficient of determination, path coefficients, indicator of Stone-Geisser, and Cohen's indicator. We evaluated item factor loadings and average variance extracted for model measurement. We tested the internal consistency with Cronbach's α test and composite reliability and evaluated the discriminant validity by adopting Fornell and Larcker (1981) criteria. We tested the original and a new three-factor model and performed correlational and variance analyses as additional tests. The new three-factor theoretical model had stronger structural support and better discriminant and convergent validities than the original three-factor model. The ABIS total score was inversely correlated with body appreciation. There were significant body image score differences between the groups of sedentary and physically active amputees and among those with differences in years since amputation, but there were no differences between those with different causes of amputation nor for those with different amputated limbs.
