This study examined differences between Wechsler Intelligence Scale for Children-Third Edition (WISC-III) and Wechsler Intelligence Scale for Children-Revised (WISC-R) scores for 40 elementary students with learning disabilities. WISC-III Full Scale, Verbal, and Performance scores were lower than comparable WISC-R scores by one-third to one-half a…

A brief overview is provided of the Conger-Lipshitz approach to estimating the reliability of a profile or test battery. A computational example from a recent study shows how canonical reliability can be obtained through existing statistical software. (SLD)

Presents data from the development and testing of an instrument created to evaluate the oral health of nursing home residents by nursing personnel. Examination of 100 residents by dentists and 3 categories of trained nurses established statistically significant interrater reliability, suggesting that nursing staff can be taught to evaluate the…

To determine whether the visuospatial n-back working memory task is a reliable and valid measure of cognitive processes believed to underlie intelligence, this study compared the reaction times and accuracy of performance of 70 participants, with performance on the Multidimensional Aptitude Battery (MAB). Testing was conducted over two sessions…

The aim of this study was to examine the psychometric properties of a Spanish version of the Social Skills Scale of the Social Skills Rating System-Teacher Form (SSRS-T) with a sample of children attending elementary schools in Puerto Rico (N = 357). The SSRS-T was developed for use with English-speaking children. Although translated, adapted, and…

The High School and Beyond study is a national large-scale longitudinal survey of a representative sample of approximately 58,000 high school students. Information was collected at various stages from 1980-1986, on over 1,500 variables including achievement in six different areas measured by a 126-item cognitive test. Previous analyses of the…

This study assessed the interchangeability of the Matthews Youth Test for Health (MYTH) and Hunter-Wolf A-B Rating Scale. Data from 25 elementary teachers and 300 of their students showed these scales to be weakly correlated, and the concordance of their A-B classifications to be only slightly above that expected by chance. Weak agreement was…

Comparisons of corresponding values of phi and kappa coefficients were made for 270 instances of data generated by a Monte Carlo technique to simulate a test-retest situation. Data were generated for distributions with the same mean but three different levels of standard deviation, standard error of measurement and cutting score. Ten samples of…

THE JOHNS HOPKINS PERCEPTUAL TEST (JHPT), REVIEWED IN THIS PAPER, WAS DESIGNED TO MEET THE NEED FOR A BRIEF, EASILY ADMINISTERED, NON-VERBAL INSTRUMENT TO ASSESS THE INTELLECTUAL FUNCTIONING OF CHILDREN. THE DATA ON THIS INSTRUMENT INDICATES THAT IT IS RELATIVELY CULTURE FAIR AND USEFUL FOR TESTING CHILDREN WHOSE PHYSICAL HANDICAPS PRECLUDE THE…

Livingston's reliability coefficients and Harris' indices of efficiency were computed along with the classical internal consistency coefficients, KR-20's (Kuder-Richardson internal consistency coefficient), for 678 criterion-referenced tests in the A through E levels of an individualized mathematics program. The coefficients were carefully studied…

The Wechsler Intelligence Scale for Children, and the revised form of that measure, were administered to a sample of sixth grade pupils. Although the correlation between measures was high, scores on the revised form were significantly lower. (JKS)

The Myers Briggs Type Indicator is a self-report inventory developed to measure variables in Carl Jung's personality typology. The four personality scales measured by the instrument, and the scoring process are described, and an extensive review of the intercorrelation, reliability, and validity research is presented. (Author/MV)

This study derives the economic costs of misclassification in nursing home patient classification systems. These costs are then used as weights to estimate the reliability of a functional assessment instrument. Results suggest that reliability must be redefined and remeasured with each substantively new application of an assessment instrument.…

Providing additional data concerning the reliability and discriminant validity of Aiken's Enjoyment of Mathematics and Value of Mathematics Scales resulted in a degree of correlation between scales lower than for Aiken's data. Also, the view that the scales measure different aspects of attitude toward mathematics was supported. (PN)

The Self-Description Questionnaire III (SDQ III) was designed to measure 13 factors of self-concept. The reliabilities of the factors were high, and correlations among them were low. Academic achievement measures in language and mathematics were correlated with self-concepts in the same areas but not with other self-concept factors. (Author/DWH)
