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

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

“…Nevertheless, it should be noted that adequate fit was obtained following the freeing of error covariances between items #1 and #9. Although this procedure is consistent with some previous BAS-2 translational studies (e.g., Geller et al, 2020;Junqueira et al, 2019;León et al, 2021), it is suggestive of possible item-content overlap. When analyzing the semantic content of these items, we identified that, in the Portuguese language, the adjectives "good" and "comfortable" can have a similar interpretation.…”

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

“…Furthermore, in the Western socio-cultural context, girls are objectified to a higher extent and socialized to care for their physical appearance and attractiveness (e.g., Daniels et al 2020 ). All of these — and the fact that puberty brings adolescent boys closer to the muscular ideal whereas girls move further from the thin ideal (Paquette et al 2022 ) — could stand behind the previous research results that found higher body appreciation in adolescent boys than girls (Escoto Ponce de León et al 2021 ; Góngora et al 2020 ; Paquette et al 2022 ).…”

“…The measurement of body appreciation is crucial in both research and practice, so Body Appreciation Scale-2 (BAS-2; Tylka and Wood-Barcalow 2015a ) was developed and adapted to multiple languages, including Dutch (Alleva et al 2016 ), Danish, Swedish, Portuguese (Lemoine et al 2018 ), Polish (Razmus and Razmus 2017 ), Spanish (Swami et al 2017 ), Romanian (Swami et al 2017 ), Italian (Casale et al 2021 ), Mandarin Chinese (Ma et al 2022 ), German (Behrend and Warschburger 2022 ), Korean (Lee 2023 ), and others. The above-mentioned research has documented the scale’s validity, most recently in the adolescent population (Escoto Ponce de León et al, 2021 ; Góngora et al 2020 ; Lemoine et al 2018 ; Paquette et al 2022 ).…”

“…Furthermore, adolescence is characterized by substantial physical and psychosocial developmental changes, including those related to body image, such as body shape and weight alterations, the increased awareness of physical appearance, and susceptibility to appearance-related peer pressure (Markey 2010 ). Accordingly, body appreciation seems to vary during adolescence, when younger adolescents reported higher body appreciation than older adolescents, although with a rather small effect magnitude (Escoto Ponce de León et al 2021 ).…”

“…While gender invariance has been more thoroughly investigated for the BAS-2, to our best knowledge, age invariance has been insufficiently verified in adolescent samples; only Escoto Ponce de León et al ( 2021 ) examined and supported the scale’s age invariance for Mexican adolescents. Yet, rapid developmental changes in body image and age differences in body appreciation during adolescence urge the need for the comparability of body appreciation across different adolescent age groups.…”
