The Immaturity (IMM) Scale was developed as a supplementary scale for the Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A). This study describes the development of the IMM Scale and presents some concurrent validity data derived from the MMPI-A normative sample of 1,620 adolescents and a clinical sample of 122 adolescent inpatients. The IMM Scale was examined in relation to Biographical and Life Events data to identify external correlates for the MMPI-A normative sample. In the clinical sample, external correlates were derived from diagnostic and rating form data provided by the adolescents' treatment staff and by their parents. Current findings were discussed in terms of the relationship of correlate patterns to descriptions of the preconformist and conformist stages of Loevinger's (1976) concept of ego development, and future research directions were suggested.

Minnesota Multiphasic Personality inventory (MMPI) norms developed by Marks and Briggs (1967/1972) have served as the standard adolescent norms used for over 10 years. Additional adolescent, norms, have recently been produced by Gottesman, Hanson, Kroeker, and Briggs (1987) and by Colligan and Offord (1989), thereby providing MMPI users with a potential choice of adolescent norms. Our study examines the effects of these adolescent norm sets on single-scale and profile elevations. In addition, we examine the ability of these norm sets to generate T-score values that would serve to discriminate accurately among adolescents in outpatient (n = 100), inpatient (n = 100), and normal (n = 100) settings. Results indicated teat the choice of adolescent norms resulted in important differences in profile elevation. Findings from the discriminant function analyses, however, indicated that these normative sets were roughly equivalent in discrimmating among adolescents in the three settings.

Among the most consistent criticisms of the Minnesota Multiphasic Personality inventory (MMPI) has been the adequacy of the standardly employed adult norms. Recent work at the Mayo Foundation has provided revised adult norms, and the Restandardization Project at the University of Minnesota Press will soon provide an additional norm set. This article reviews findings from 21 studies of normal adults, comparing obtained MMPI scale values to the standard norms. These comparisons indicate that the traditional adult norms may have contained detectable degrees of bias since their publication, and that consistent patterns of differences from standard MMPI norms can be found in independent studies published as early as 1949. Two separate considerations impact on the development of new adult norms: the research need for adult norms which accurately reflect the response patterns of the general population and the clinical need to evaluate individual psychiatric patients on norms that produce codetypes related to an empirical literature spanning more than 40 years. This study notes the inherent tension between these two purposes and discusses the implications of new adult MMPI norms for research and clinical practice. [ABSTRACT FROM AUTHOR]

This article examines central issues involving the accuracy of Minnesota Multiphasic Personality Inventory (MMPI) adolescent norms through examination of findings from eight investigations (n = 17,286), reporting MMPI mean values for samples of normal adolescents conducted between 1949 and 1964, and four studies (n = 1,758), based on adolescent samples collected since 1975. Issues related to sex and racial differences in adolescent samples are also examined. In addition, MMPI data from 1,315 normal adolescents, collected at the Mayo Foundation, and from 217 normal adolescents, collected in Norfolk, Virginia, are evaluated in relation to adult normative values on the Harris-Lingoes (Harris & Lingoes, 1955) content subscales to identify unique characteristics of adolescents' response patterns. Results support the adequacy of the adolescent norms, developed by Marks, Seeman, and Hailer (1974), for evaluation of samples of normal adolescents collected between 1947 and 1965. MMPI patterns, produced by contemporary samples of adolescents collected since 1975, are elevated above the Marks et al. norms on most clinical scales. This latter finding indicated the need for the development of new adolescent norms that more precisely reflect current adolescent response frequencies and patterns. Finally, results from Harris-Lingoes subscales are reviewed to highlight unique aspects of adolescent developmental experience and to underscore the necessity of development of age appropriate adolescent norms for MMPI special scales.

This study examined the agreement or congruence rate between clinical-discharge diagnoses rendered by a psychiatrist, and admission and discharge MMPI-derived diagnoses from four diagnostic classification systems that have been developed for the MMPI. The four classification systems included a simple high-point code based on the most elevated clinical scale in the profile, the Henrichs revision of the Meehl-Dahlstrom rules, the Goldberg equations, and a system developed by Lachar. Subjects consisted of 150 patients selected from a larger pool of patients who had completed a 9-week adult residential treatment program. Overall, this study yielded modest hit rates between 26% and 34% for MMPI-derived diagnoses and psychiatric diagnoses across the various classification systems. In addition, stability of MMPI-based diagnoses from admission to discharge assessments ranged from 48% to 51% depending on the classification system employed. Findings are discussed in terms of their implications for the use of the MMPI in patient diagnosis. It is recommended that the MMPI be used in conjunction with other sources of clinical and test information in deriving clinical diagnoses. [ABSTRACT FROM AUTHOR]

This study examined the relationship of Minnesota Multiphasic Personality Inventory (MMPI) measure, including the MacAndrew alcoholism (MAC) scale, and the Sensation Seeking Scales (SSS) to adolescents drug use across nine drug categories. Subjects were 51 male and 72 female high school students between the ages of 14 and 18 (mean age = 16 years, 5 months). The drug use/abuse measure consisted of adolescents' self-reports on the Segal (1973) Alcohol-Drug Use Research Survey. Drug categories included for investigation were alcohol amphetamines, barbiturates, caffeine, cocaine, hallucinogens, marijuana, narcotics, and tobacco. Scores from standard MMPI scales, the MAC scale, and the SSS were examined in relation to individual drug use outcomes, and multivariate procedures were used to predict polydrug versus single drug use patterns. Results demonstrated significant and meaningful relationships between personality measures and drug use among adolescents, with consistently strong findings for the SSS. [ABSTRACT FROM AUTHOR]
