The Personal and Academic Self-Concept Inventory (PASCI) measures global, social, physical, and academic components of self-concept, as well as social anxiety. Several competing structural models were tested by confirmatory factor analysis for a sample of high school (N = 222) and college (N = 338) students. Seven oblique factors which included two social factors (Social Acceptance and Social Anxiety) fit the data best, and a second-order model supported the hierarchical structure of the data. Internal-consistency and test-retest measures indicated that the scales were reliable. Girls and women scored lower than the boys and men on Physical Ability and on Math Ability, consistent with other findings. Self-Concept scales were stable across high school grades, but global self-concept was higher in the college group, also consistent with prior research.
