The Henmon-Nelson, Cardall-Miles, slosson and quick tests as predictors of wais IQ

Abstract

PROBLEMThis paper reports on the last in a series of four projects in which the authors have attempted to assess the abilities of short intelligence tests to predict WAIS I&. The purpose of this series was to develop data on comparable samples from the same institution that could be used t o help clinicians determine which of the many short intelligence tests available are the most effective and efficient WAIS surrogates. Reports of the first three papers in this series-evaluations of particularly common short I& tests(5', group ability tests@), and nonverbal tests(7' have been published and will be discussed later in this paper.The purpose of the project described here was to compare the WAIS-predicting abilities of four relatively common verbal intelligence tests-the Henmon-Nelson Tests of Mental Ability (Form A, Grades 9-12) ( 3 ) , Cardall-Miles Mental Alertness (2), Slosson Intelligence ( 4 ) , and Quick ( l ) tests-to one another. METHODThe WAIS and the four tests mentioned above were administered to 120 new admissions/readmissions to the St. Cloud Veterans Administration Hospital. Prior to data collection the patients' clinical files were examined to eliminate individuals who might have taken any of the five tests within the preceding 6 months. The Ss were 120 (119 male, 1 female) volunteers under 60. The staff diagnoses of the Ss were Schizophrenia (34 cases), Alcohol Addiction (24), Personality Disorder (16), Anxiety Neurosis (13), Depressive Neurosis (1 1) , Drug Dependency and Manic Depressive Psychosis (4 each), Organic Brain Syndrome, Psychophysiological Disorder, and Adjustment Reaction to Adult Life (2 each), and Obsessive Compulsive Neurosis, Involutional Melancholia, and Psychotic Depressive Reaction (1 each). Five Ss left the hospital before they had been assigned a staff diagnosis. The mean age, education, total length of psychiatric hospitalization, and WAIS Full Scale I& of the sample were 38.7 years (SD = l2.0), 10.7 years (SD = 2.5), 9.8 months (SD = 21.6) and 99.2 (SD = 12.2). The administration order of the tests was counterbalanced in an effort to neutralizr practice and fatigue effects. RESULTS AND DISCUSSIONCorrelations between the various short intelligence test scores and WAIS measures are presented in Table 1.Henmon-Nelson. As a preliminary step thch relationship between HenmonNelson raw scores and Full Scale scale scores was evaluated for curvilinearity. The resulting F was 3 3 (df = 7, l l l ) , which was nonsignificant. Therefore Pearson r was used to study the Henmon-Nelson vs. WAIS relationships. As the Table indicates, the Henmon-Nelson us. WAIS correlations were very satisfactory and indicate that the test can be used as a basis for estimating WAIS scores. However, the Henmon-Nelson I& score underestimated WAIS Full Scale IQ in our study by 15 points (mean WAlS I& = 99.2; mean Henmon-Nelson I& = 84.4). The variabilities of the samplc on the two tests were very similar (SD = 12.2 for WAIS Full Scale I& and 13.2 for Henmon-Nelson IQ), Thus persons who desire to use the ~ 'The a...

The construct validity of an aftereffect-based subtyping system for alcoholics

“…Only men whose primary chemical problem was alcohol were included; however, approximately 30% of the patients in the program also reported at least sporadic use of street drugs, usually marijuana, as well. The mean age, education, and HenmonNelson estimated Wechsler Full Scale IQ (Watson & Klett, 1975) of the sample were 40.1 years (SD = 11.6), 11.6 years (SD = 2.2), and 109.9 (SD = 12.9).…”

Correlates of alpha, beta and theta wave production

“…All were individuals whose physician and ward nurse had agreed that the patient exhibited substantial anxiety, depression, or both. The mean age, education, months of previous psychiatric hospitalization and Henmon-Nelson-based estimates of WAIS Full Scale I& (Watson & Klett, 1975) of the sample, and their standard deviations, were 36.3 years (S = 11.3), 12.3 years (S = 2.2), 110.9 (S = 13.4), and 16.4 months (S = 34.4), respectively. Thirty-five of the patients were taking major tranquilizers a t the time of the study.…”

The comparative concurrent validities of the Shipley Institute of Living Scale and the Henmon-Nelson Tests of Mental ability

“…We (Klett, Watson, & Hoffman, 1986; Watson & Klett, 1968& Klett, , 1973& Klett, , 1974& Klett, , 1975; Watson et al, 1981) compared the abilities of the Shipley and 14 other brief intelligence tests to predict WAWWAIS-R IQs in a psychiatric hospital. The resulting concurrent validity coefficients varied greatly (rs from -3 5 to .85).…”
