Black/white IQ differences: does age make the difference?

Data are presented on racial differences from the norms of the Kaufman Assessment Battery for Children, the recent renorming of the Wechsler Adult Intelligence Scale-Revised, the Stanford-Binet IV, and Raven's Progressive Matrices. The premise of the present article is that, while the one standard deviation IQ difference between Black and White adults has remained constant, IQ differences between Black and White children are declining. These data are discussed in the context of previous studies on possible racial bias of IQ tests, as well as marked changes in educational and economic opportunities that have occurred in the United States in the decades since Jensen's (1969) article.

The Exner Rorschach: an analysis of its clinical validity.

Data from Exner's 1985 and 1989 normative samples on nonpatient adults and comparison samples of patients with schizophrenia, depression, and character problems were reanalyzed using a standard of clinical significance appropriate for N = 1. The 1989 norms, which exclude Rorschach protocols with less than 14 responses, alter not only the number of significant variables, but also alter the ability of most variables that relate to form quality to differentiate among the patient comparison groups. The Exner Rorschach is judged to be a valid test for schizophrenia, but to have demonstrated little differential utility for depression and character disorders. It is recommended that the scoring of nonsignificant variables be abandoned.

Construct validity of the Diagnostic Inventory of Personality and Symptoms: external correlates.

This study extended knowledge of the construct validity of Vincent's Diagnostic Inventory of Personality and Symptoms (DIPS) by examining the relationships between the DIPS and the MMPI, the Millon Clinical Multiaxial Inventory, the Profile of Mood States, the Symptom Check List-90, and the California Psychological Inventory. Subjects were 300 predominantly male psychiatric inpatients. Correlational analyses revealed that the DIPS clinical scales were related most strongly to MMPI and MCMI clinical scales. Eleven of 14 DIPS clinical scales showed clinically significant correlations with similar scales of the external measures. The validities of the Stress-Adjustment Disorders and Psychological Factors Affecting Physical Condition scales were not ascertained directly.

The fragile nature of MMPI code types.

The percent of code type agreement with the original MMPI is compared with the new MMPI-2, an earlier re-norming of the MMPI by Colligan, Osborne, Swenson, and Offord (1983), the MMPI-168, and test/retest comparisons of the MMPI with itself. Code type agreement ranges from lows of 31 to 41% for the test/retest comparability of the original MMPI with itself to 40 to 67% hit rates for the MMPI-2, the MMPI 1983 norms, and the MMPI-168. The effect of this on interpretation is discussed in the context of previous studies on the MMPI code types in relation to broadband diagnosis and comparisons of clinical accuracy of computerized reports that have utilized various MMPI versions.

DSM-III-R diagnosis and code types of the diagnostic inventory of personality and symptoms in an adolescent clinical population.

The relationships of high-point code types of the Diagnostic Inventory of Personality and Symptoms (DIPS) to the Diagnostic and statistical manual III-R (DSM-III-R; American Psychiatric Association, 1987) were explored for adolescent patients (N = 263). Twelve DIPS code types that relate code types to Axis I diagnoses are prepared. The three DIPS personality disorder cluster scales and the eight combinations thereof are presented as well. Six of the personality disorder cluster scale code types that relate to DSM-III-R Axis II categories are identified. Finally, a narrative summation of each of the code types is given.

Psychological profile of patients with Menière's disease.

Forty-eight patients with Menière's disease underwent psychological assessment with the Minnesota Multiphasic Personality Inventory and Diagnostic Inventory of Personality and Symptoms. Using the presence or absence of recurrent vertigo or chronic dysequilibrium as the differentiating feature, the results of two groups were compared. A clinical diagnosis of depression (axis I) was evident in 80% of the patients with active vestibular symptoms examined by the Minnesota Multiphasic Personality Inventory and 70% by the Diagnostic Inventory of Personality and Symptoms compared with 32% (Minnesota Multiphasic Personality Inventory) and 39% (Diagnostic Inventory of Personality and Symptoms) in the inactive group. The data support the addition of depression to the clinical picture of active Menière's disease.

DSM-III diagnosis and code types of the Diagnostic Inventory of Personality and Symptoms in public hospital settings.

The relationships of high-point code types of the Diagnostic Inventory of Personality and Symptoms (DIPS) to the Diagnostic and statistical manual III of the American Psychiatric Association (DSM-III) were explored for public hospital patients (N = 448). Nineteen DIPS code types that relate code types to Axis I diagnoses are prepared. The three DIPS personality disorder cluster scales and the eight combinations thereof are presented as well. Eight of the personality disorder cluster scale code types that relate to DSM-III Axis II categories are identified. Finally, a narrative summation of each of the code types is given.

The modified WAIS: an alternative to short forms.

The Modified WAIS is an approach for shortening the total administration time of the WAIS by approximately 25%. The Modified WAIS uses the Information subtest as a criterion for raising the point at which initial questioning begins on 5 of the 11 subscales. The Modified WAIS was shown to correlate quite highly with the Standard WAIS: .999 for Verbal, Performance, and Full Scale IQ (N = 200). While the number of cases for which the Modified WAIS is applicable will vary from setting to setting depending on the number of cases that meet the criterion, the Modified WAIS appears to be a viable alternative to short forms.

Parental involvement as a requisite for successful adolescent therapy.

The effect of parental involvement in the treatment program of 66 consecutive adolescent patients is analyzed. Adolescents whose parents participated regularly in a parents' group or in individual parental consultation and therapy achieved a 64% success rate, using narrow success criteria. For those adolescents whose parents were not involved in the treatment process, the failure rate was virtually 100% (chi2=21.07, p less than 0.001). There was no statistically significant difference in treatment outcome between the cohorts of parental involvement. However, a parents' group is recommended where feasible in lieu of individual parent consultation alone for reasons of catharsis, universality, mutual support, and collective experience.

The relationship between stressful life events and hospitalized adolescent psychiatric patients.

The nature and magnitude of psychosocial stresses preceding adolescent hospitalization were investigated. The findings indicate that the adolescent psychiatric patients have a greater magnitude of stressful life events when compared with general hospitalized adolescents and normal adolescents. The difference is found to be largely quantitative rather than qualitative. The results of the present study utilizing a combined version of Coddington's Junior High School and Senior High School Social Readjustment Rating Questionnaires is similar to previous findings on adult populations using the Social Readjustment Rating Scale.

Validity of the MMPI 168 on private clinic subpopulations.

The diagnostic efficiency of the MMPI 168 and the standard MMPI was compared on three private psychiatric subpopulations: a hospitalized adult inpatient sample, a hospitalized adolescent inpatient sample, and an outpatient sample composed of vocational rehabilitation referrals. The MMPI 168 was found to be a viable alternative to the standard Form R on all three groups by separating invalid from valid profiles, normal from abnormal profiles, and by differentiating among neurotic, psychotic, characterological, and indeterminate profiles.

Capgras syndrome: case report of an adolescent and review of literature.

Case report of an adolescent with Capgras Syndrome in the absence of organic brain syndrome is presented. Four cardinal features associated with Capgras Syndrome--(1) moderate-to-severe anxiety or stress, (2) ambivalent love-hate relationships with important love objects, (3) body image distortion, and (4) rejection-abandonment phenomena--were developed vis-a-vis the developmental tasks of adolescence. The literature consisting of 75 case reports is reviewed from the standpoint of differential diagnosis especially with respect to organic brain syndromes and schizophrenia.
