The Immaturity (IMM) scale was developed for the Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) to provide an objective measure of ego development or maturation. The present study examines the concurrent validity of the IMM scale based on a residential treatment sample of 66 adolescents, ages 13 through 18 years. Participants were administered the MMPI-A, the Defining Issues Test (DIT), a short form of the Washington University Sentence Completion Test (WUSCT), the Extended Objective Measure of Ego Identity Status-2nd Revision (EOM-EIS-2), and standardized measures of intelligence and reading ability. The results of this study provide evidence of the concurrent validity of the IMM scale, and a number of correlate descriptors are reported for the IMM scale.
