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 co
mpetence, social acceptance, athletic competence, physical appearance,
romantic appeal, conduct/morality, close friendships, job competence
and, in addition, global self-worth. Separate items relating to mathem
atics and English abilities were added. The internal consistencies wer
e generally high. Results from factor analysis provided strong support
for the a priori dimensions, the multidimensional conceptualisation o
f the self-concept, thereby confirming Harter's (1985a) model.
