Conjectures and refutations in cognitive ability structural validity research
Latent profile analysis of classroom behavior problems in an American national sample of prekindergarten children
Problematic behaviors impede young children's ability to succeed in the classroom. Examining individual patterns of behavior problems allows researchers to identify profiles of students most in need of support. This study applied latent profile analysis (LPA) among a national sample ( N = 2764) of American prekindergarten children and found six distinct behavior profiles, which differed in the severity and type (underactive vs. overactive) of beh…

Construct validity of the Wechsler Intelligence Scale For Children – Fifth UK Edition
BACKGROUND: ; Wechsler, 2016a, Wechsler Intelligence Scale for Children-Fifth UK Edition, Harcourt Assessment, London, UK) to guide interpretation. AIMS AND METHODS: was examined using complementary exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) for all models proposed by Wechsler (2016b, Wechsler Intelligence Scale for Children-Fifth UK Edition: Administration and scoring manual, Harcourt Assessment, London, UK) as well…
Exploratory Factor Analysis
Exploratory factor analysis (EFA) is a multivariate statistical method that has become a fundamental tool in the development and validation of psychological theories and measurements. However, researchers must make several thoughtful and evidence-based methodological decisions while conducting an EFA, and there are a number of options available at each decision point, some better than others. Reviews of the professional literature have consistent…
The reliability of multidimensional neuropsychological measures
OBJECTIVE: To demonstrate that Coefficient omega, a model-based estimate, is more a more appropriate index of reliability than coefficient alpha for the multidimensional scales that are commonly employed by neuropsychologists. METHOD: As an illustration, a structural model of an overarching general factor and four first-order factors for the WAIS-IV based on the standardization sample of 2200 participants was identified and omega coefficients wer…
Construct validity of the Wechsler Intelligence Scale for Children - Fourth UK Edition with a referred Irish sample
BackgroundIrish educational psychologists frequently use the Wechsler Intelligence Scale for Children - Fourth UK Edition (WISC-IVUK; Wechsler, 2004, Wechsler Intelligence Scale for Children-Fourth UK Edition, London, UK, Harcourt Assessment) in clinical assessments of children with learning difficulties. Unfortunately, reliability and validity studies of the WISC-IVUK standardization sample have not yet been reported. Watkins et al. (2013, Inter…

Incremental validity of Wisc – IV UK factor index scores with a referred I rish sample
BACKGROUND: Subtest and factor scores have typically provided little incremental predictive validity beyond the omnibus IQ score. AIMS: This study examined the incremental validity of Wechsler Intelligence Scale for Children - Fourth UK Edition (WISC-IV(UK) ; Wechsler, 2004a, Wechsler Intelligence Scale for Children - Fourth UK Edition, Harcourt Assessment, London, UK) and factor index scores in predicting academic achievement on the Wechsler Ind…
Bifactor Modeling and the Estimation of Model-Based Reliability in the Wais-IV
Previous confirmatory factor analytic research that has examined the factor structure of the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) has endorsed either higher order models or oblique factor models that tend to amalgamate both general factor and index factor sources of systematic variance. An alternative model that has not yet been examined for the WAIS-IV is the bifactor model. Bifactor models allow all subtests to load onto b…
Factor Structure of the Wechsler Intelligence Scale for Children–Fourth Edition Among Referred Students
Factor analysis was applied to the Wechsler Intelligence Scale for Children–Fourth Edition (WISC-IV) scores of 432 Pennsylvania students referred for evaluation for special education services to determine the factor structure of the WISC-IV with this population. A first-order, four-factor oblique solution that mirrored that found in the WISC-IV normative sample was supported. When transformed to an orthogonalized higher order model, the general f…
Factor Structure of the Wechsler Intelligence Scale for Children–Third Edition among Gifted Students
Factor analysis was applied to the Wechsler Intelligence Scale for Children–Third Edition (WISC-III) scores of 505 gifted students to evaluate the construct validity of the WISC-III with this population. Multiple criteria were used to determine the number of factors to retain for principal axis extraction. A two-factor solution that roughly mirrored the verbal comprehension and perceptual organization factors of the WISC-III normative sample appe…
A Microcomputer Basic Program to Calculate Univariable Regression Model Analysis of Test Bias
There has been increased concern over the question of whether various educational and psychological tests may be biased against certain groups. A regression-based model such as the one described by Potthoff (1966) is presently considered one of the most tenable procedures for appraising bias in psychological testing. This paper presents a BASIC microcomputer program which calculates a regression model based analysis of predictive bias
A Microcomputer Basic Program to Calculate the Level of Agreement Between Two Raters Using Nominal Scale Classification
A simple percentage measure of agreement among raters using nominal scales may provide misleading reliability information. Scott's Pi and Cohen's Kappa are two chance-corrected statistics which have been widely utilized in assessing interrater agreement. This paper presents a BASIC microcomputer program which calculates these two chance-corrected measures of interrater reliability
A Computer Program for Measuring Levels of Overall and Partial Congruence Among Multiple Observers on Nominal Scales
A computer program entitled Program CONGRU is presented which analyzes the overall conjoint agreement among many observers for their classifications on categorical scales. A special feature assesses the significance of observers' congruence in assignments to each nominal category considered
A Fortran Program for Testing Agreement of Multiple Observers With a Categorical Standard on Nominal Scales
A computer program entitled Program STANDARD is presented which assesses the significance of the conjoint agreement of many observers with a standard or "correct" set of choices for assignments of subjects or objects on nominal scales

Correlation between Quick Word Test and Sixteen Personality Factor Questionnaire B Factor Scores
A correlation of .37 between scores on Sixteen Personality Factor Questionnaire source trait B and scores on the Quick Word Test of 104 male and 141 female American college students was calculated. It was concluded that Factor B's validity as an individual assessment of intelligence is not supported for this sample of college students
Effects of Parental Presence on Attendance and Input of Interdisciplinary Teams in an Institutional Setting
The present study examined the effect of parental involvement in interdisciplinary team meetings in a residential institution for the mentally retarded. At random from records of annual evaluative conferences, two groups each of 55 residents were selected, one group having parents present and the other having no parents present at the staffing. Analysis of group differences was through univariate analysis of variance. When parents were present mo…
