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

Understanding the formation of body image­that is, how people view and evaluate their bodies­is crucial for the prevention and treatment of eating disorders. This is especially true in adolescence, when body image develops significantly. That being said, the psychological assessment of body image, both in research and practice, requires reliable, high-quality measurement scales. Since its development by Tylka and Wood-Barcalow (2015a), Body Appreciation Scale-2 has been routinely used to assess body appreciation, which includes positive attitudes towards one's body despite its perceived "flaws". Our study provides evidence for the quality of the Czech version of Body Appreciation Scale-2 for use with adolescents. We examined the scale's characteristics on data from two robust samples (613 and 1530 Czech adolescents). Our study showed that the qualities of Czech Body Appreciation Scale-2 are satisfactory, and we recommend the scale for the assessment of body appreciation for adolescents in the Czech context. We also documented that the scale scores can be accurately compared between adolescent girls and boys, and younger (13­15) and older (16­18) adolescents. Additionally, we discovered gender differences in the relationships between body appreciation and depressive moods and the internalization of media ideals, which demands further exploration in future research.
