A literature review on positive body image and adolescence was conducted, which shaped the development of the Positive Body Image among Adolescents Scale (PBIAS). In Study 1, four focus groups (totaling 14 adolescents) from Belgium explored the content, clarity, and applicability of the PBIAS items. In Study 2, an exploratory factor analysis (N = 565; Mage = 14.9, 63.8 % girls) revealed 4 factors body self-appreciation, body other-appreciation, resilience against media body ideals, and resilience against negative appearance feedback. This 4-factor structure was confirmed in Study 3 (N = 718; Mage = 15.2, 50.4 % girls), and gender invariance was upheld. The test-retest reliability of the PBIAS scores was partially supported in Study 4 (N = 309, Mage = 15.3, 66.3 % girls). Across studies, internal consistency was supported and construct validity (convergent and incremental) evidence was garnered. Further, the PBIAS was translated from Dutch to English to offer researchers an option for collecting data in English-speaking countries. Overall, the PBIAS is a brief measure with psychometric support that assesses four dimensions of adolescent positive body image. Improve understanding of the links between biological variables (sex, body size and anatomical position) and adaptive remodelling of autopodia, and the identification of traction use in the archaeological record. A modified version of the recording system for identifying draught cattle in the archaeological record (Bartosiewicz et al., 1997) was applied to a sample of 1509 bones from six sites from medieval England. Analysis focused on identifying correlations between pathological and sub-pathological changes in lower-limb bones in relation to anatomy, sex and body mass. A correla
