Extending the use of the Body Appreciation Scale -2 in older adults: A Portuguese validation study.

Body appreciation is a key characteristic, and the most common operationalization, of positive body image. Positive body image is often measured using the Body Appreciation Scale-2 (BAS-2; Tylka & Wood-Barcalow, 2015a), which has demonstrated good psychometric properties in adult samples. The purpose of this study is to extend the validation of the BAS-2 to late adulthood facilitating future research with this population. A total of 202 male and female participants (aged 65-91 years) completed the Portuguese version of the BAS-2, along with other body image-related instruments and measures of self-esteem and intuitive eating. Confirmatory factor analysis supported the one-factor model and demonstrated sex invariance. There were no significant sex differences in BAS-2 scores. The BAS-2 had satisfactory convergent, discriminant, and incremental validity. Internal consistency and test-retest stability estimates were adequate. The BAS-2 will likely meet the needs of researchers interested in exploring body appreciation among elderly people.
