Abstract
This study investigates the conceptual issues, theoretical rationale, construct validity, psychometric properties, and empirical analysis of the Self‐Perception Profile for Adolescents (Harter, 1986). The scale was administered to 283 students (average age 13.1 years, 49% female) from 12 Year 7 classes in three non‐selective systemic high schools. The scale assesses competence in 8 self‐concept domains: scholastic competence, social acceptance, athletic competence, physical appearance, romantic appeal, conduct/morality, close friendships, job competence and, in addition, global self‐worth. Separate items relating to mathematics and English abilities were added. The internal consistencies were generally high. Results from factor analysis provided strong support for the a priori dimensions, the multidimensional conceptualisation of the self‐concept, thereby confirming Harter's (1985a) model.
