The 10-item Body Appreciation Scale-2 for Children (BAS-2C; Halliwell et al., 2017) is a measure of positive body image that assesses the degree to which children appreciate and accept their bodies, respect their bodies by attending to their needs, and the influence of inner positivity on outer demeanour. The BAS-2C can be administered online or in-person to children and is free to use in any setting. This chapter first discusses the development of the BAS-2C, followed by evidence of its psychometric properties. More specifically, the Body Appreciation Scale-2 for Children has been found to have a unidimensional factor structure within exploratory and confirmatory factor analyses, with mixed evidence of measurement invariance across gender. Internal consistency reliability, test-retest reliability, convergent validity, and construct validity support the use of the BAS-2C. Next, this chapter provides the BAS-2C items in their entirety, instructions for administering the BAS-2C, the item response scale, and the scoring procedure. Abbreviated forms are offered, and known translations are provided. Logistics of use, such as permissions, copyright, and contact information, are provided for readers.
