Two types of social goals associated with students' academic performance have received attention from researchers. One is the social responsibility goal and the other is the social relationship goal. While several scales have been validated for measuring social relationship and social responsibility goals in academic settings, few studies have applied these social goal scales to high school students in physical education settings. The purpose of this study was to assess the reliability, validity, and generalizability of the scores produced by the Social Goal Scale-Physical Education (SGS-PE) in high school settings. Participants were 544 students from two high schools in the southern United States. Reliability analyses, principal components factor analysis, confirmatory factor analysis, and multistep invariance analysis across two school samples revealed that the SGS-PE produced reliable and valid scores when used to assess students' social goal levels in high school physical education settings.
