title: MMPI and Rorschach indices of schizophrenic and depressive diagnoses among adolescent inpatients.
abstract: Although adolescent norms have been developed for the MMPI (e.g., Marks, Seeman, & Haller, 1974) and Rorschach (e.g., Exner, 1986a), little is known regarding the discriminate diagnostic validity of these measures with adolescents. This study investigated the usefulness of these measures in the detection of depression and schizophrenia among adolescent inpatients. Subjects (mean age = 15.3) consisted of 134 adolescents who received Rorschach and MMPI administrations at hospital admission. Clinical diagnoses resulted in the following groupings for this sample: schizophrenia = 15, dysthymic disorder = 41, major depression = 26, conduct disorder = 28, personality disorder = 18. MMPI scale Sc elevation was found to be the most effective single predictor of schizophrenic diagnoses, with a hit rate of .76, sensitivity of .62, and specificity of .78. Neither MMPI scale D scores nor Rorschach DEPI scores were found to be significantly related to patients' diagnoses. Results were interpreted in terms of prior findings in adult psychiatric populations and in relation to implications for the clinical assessment of adolescents.
