MMPI-2: reliability with college students.

This study examined the temporal stability and internal consistency of the MMPI-2 in a sample of 128 college students. Mean score comparisons revealed significant differences across a number of scales, but in each case mean differences were slight and viewed as clinically insignificant. Moderate to high stability coefficients were obtained, from .60 to .90 (median of .74). Alpha coefficients ranged from .39 to .91 (median of .62). Analysis of individual difference scores revealed that for each scale approximately 20% of the sample had discrepancy scores that reached or exceeded 10 T-score points (i.e., one standard deviation). Findings are discussed relative to the reliability of the MMPI-2 in clinical assessment.

Situational variation in problem behavior at home and school in attention deficit disorder with hyperactivity: a factor analytic study.

The present investigation assesses situational variation in problem behaviors of children with Attention Deficit Disorder with Hyperactivity. Principal-component factors (VARIMAX rotation) were computed for the Home/School Situations Questionnaires (HSQ/SSQ). For the HSQ, four factors emerged, accounting for 61% of variance. For the SSQ, three factors emerged, accounting for 68% of variance. Factors were similar to those previously derived with non-referred children. To assess discriminative power, factors were compared (t-tests) to previous data. All factors significantly discriminated ADD/H from non-referred children. These data suggest the factors add to the utility of the HSQ/SSQ in assessing ADD/H.

Factor structures of the Home Situations Questionnaire and the School Situations Questionnaire.

Examined the factor structures of the Home Situations Questionnaire (HSQ) and the School Situations Questionnaire (SSQ). The sample included 955 (505 boys, 490 girls) ages 4 through 11 years old. Separate principal components factor analysis with Varimax rotations were computed for the HSQ and the SSQ. For the HSQ, four factors emerged, accounting for 57% of the variance. For the SSQ, three factors emerged, accounting for 71% of the variance. Factors are briefly discussed. Factor means, standard deviations, and significant cutoff points are provided for clinical use.

Luria Memory Words Test and Wechsler Memory Scale: comparison of utility in discriminating neurologically impaired from controls.

Memory deficits are among the most common initial complaints of patients who are suffering from neurological disorders. The present study compared the relative clinical utility of the Wechsler Memory Scale and the Luria Memory Words Test in differentiating brain-damaged (N = 60) from non-brain-damaged patients (N = 60). Separate stepwise regression analyses selected five variables from each test that accounted for the greatest between-group variance. Separate discriminant functions then were computed that used the WMS and the Luria Words variables selected through the regression analyses. The WMS correctly classified 72% of the subjects, whereas the Luria Words correctly classified 76% of the subjects. A final discriminant function was computed that used all 10 variables and resulted in a classification accuracy of 86%, with 6% false positives and 6% false negatives. Results are discussed relative to the use of each instrument in both a general psychological assessment situation and when specific memory functioning is in question.

Situational variability in boys and girls identified as ADHD.

The present investigation (N = 60) examined HSQ and SSQ (Home Situations Questionnaire/School Situations Questionnaire) protocols across individual items and recently developed factoral dimensions. The purpose was to assess the degree to which situational variability in behavior may prove sensitive to sex differences in ADHD children. Results did not support clear gender differences in children identified as ADHD.

The PPVT-R as a measure of psycholinguistic functioning: a caution.

The present investigation was undertaken to evaluate the use of the PPVT-R as a measure of psycholinguistic functioning. The sample included 75 school-aged children referred for evaluation. The mean PPVT-R standard score (94.59, SD = 15.85) was not significantly different (p less than .01) than the WISC-R Full Scale IQ (95.36, SD = 16.29), Verbal IQ (94.36, SD = 16.17), or Performance IQ (97.75, SD = 15.61), or the mean ITPA PLQ. The PPVT-R correlated positively and significantly with the WISC-R Full Scale IQ (.77), Verbal IQ (.71) and Performance IQ (.74) and the WISC-R subtests, with coefficients that ranged from .42 (object assembly) to .69 (vocabulary). In addition, the PPVT-R correlated positively and significantly with the ITPA Psycho-Linguistic Quotient (PLQ) (.72) and the ITPA) subtests, with coefficients that ranged from .38 (auditory sequential memory) to .72 (grammatic closure). Regression analyses determined that the ITPA PLQ and the PPVT-R standard score were not predictive of one another. The data are interpreted to suggest that the PPVT-R is not more appropriately used as a measure of receptive language ability than as a screen for intellectual functioning.
