The Adolescent Psychopathology Scale (APS; 1998a and 1998b) contains 20 Clinical, 5 Personality, 11 Psychosocial Problem Content, and 4 Response Style Scales. This study examined the factor structure of the 20 Clinical scales in a sample of pediatric medical institute for children (PMIC) inpatients. Participants were 162 adolescent inpatients at a state psychiatric hospital (94 boys and 68 girls) ranging in age from 12 to 17 years. Using the Principal Components method, three factors were determined with eigenvalues (11.) of 9.54, 1.83, and 1.35. These three factors accounted for 63.6% of the variance. The first factor is defined by high positive loadings for the scales that measure primarily internalizing symptomatology. The second factor is defined by high positive loadings for the scales that measure primarily externalizing symptomatology directed toward the environment. The second factor contrasted with the third factor which is also defined by high positive loadings for the externalizing symptomatology but directed toward the self. Factor loadings of the individual scales are discussed.
