Clinical utility of the WRAML screening index in neuropsychological populations

pie was 71.4% male. Diagnoses included behavioral disorders (n = 46), A D H D (n = 44), m o o d disorders (n = 40), learning disabilities (n = 37), cognitive disorder NOS (n = 17), and mixed clinical diagnoses (n = 22). Raw scores and factor scores from a two factor rotated model were used in the analysis. For the general diagnostic groups very poor discrimination was seen for both the raw (32.29% correctly classified) and factor (29.69% correctly classified) scores. Grouping the diagnoses into broader categories of A D H D (n = 44), psychiatric disturbances (n = 44), behavioral disorders (n =- 46), and learning/cognitive disorders (n = 53) improved the discriminative ability only slightly, and results were only marginally better than chance. Results of this analysis suggest that the WCST is an inadequate instrument for differentiation of neuropsychological, psychiatric, and behaviorally disturbed children.
van den Broek, A. L., Mahrou, M., Burns, W. J., & Golden, C. J. Clinical Utility of the W R A M L Screening Index in Neuropsychological Populations. The purpose of this study is to examine the clinical utility of the W R A M L Screening Index (SI) in estimating the General Memory Index (GMI) of the W R A M L in various clinical populations of children. The SI's relationship to other W R A M L indices as well as to W I S C - I I I index scores is also examined. Subjects were 200 children referred for neuropsychological testing. The average age of subjects was 10.27 years and the sample was 73.5% male. Diagnoses included: depression (n = 29), Cognitive Disorder, NOS (n = 19), behavioral disorders (n = 26), learning disabilities (n =- 45), A D H D (n = 40), mixed diagnoses (n = 26), and no diagnosis (n = 18). While the SI and G M I were significantly correlated at the p < .01 level for all groups, further analysis indicated that the SI's relationship to other W R A M L and WlSC-III indices is inconsistent between the groups. T-tests performed on SI and G M I standard scores for each group indicate significant differences in 2 of the 7 groups. Comparison of the correlations of G M I and SI to other indices scores found that of the 42 comparisons, 16 were significantly different at the p < .01 level and 2 at the p < .05 level. Results indicate that for some populations the SI should not be used in place of the GMI.
van den Broek, A. L., Devaraju-Backhaus, S., & Golden, C. J. Factor Analysis of the WCST on a Clinical Population of Children. The factor structure of the Wisconsin Card Sorting Test (WCST) has been widely researched in adult populations. The purpose of this study is to examine the factor structure and construct validity of the factors of the WCST in a clinical population of children. The subjects were 206 children referred for neuropsychological evaluations. Diagnoses included behavior disorders (n = 46), A D H D (n = 44), m o o d disorders (n = 40), learning disabilities (n = 37), cognitive disorder NOS (n = 17), and mixed clinical diagnoses (n = 22). The sample was 71.4% male with a mean age of 9.98 years. A rotated two factor solution provided the best fit to the data, and accounted for 80.6% of the variance. Factor 1 was interpreted as representing independent executive functions, and showed negative correlations with measures of intelligence and memory. Factor 2 appears to represent attentional processes and correlates positively with measures of intelligence and memory. A comparison of these findings to studies on adults is made. Additionally, the relationship of the factors to other neuropsychological tests is examined and implications for the use and interpretation of these tests in a clinical setting is discussed.
