The present study investigated the stability of scores on the WISC-IV and WAIS-IV over an approximate six-year period. Previous research using older versions of the WISC and WAIS have suggested that these scales demonstrate strong stability of scores. Since research that has compared the stability of scores between the WISC-IV and the WAIS-IV is…

Dirlikov, Benjamin; Younes, Laurent; Nebel, Mary Beth; Martinelli, Mary Katherine; Tiedemann, Alyssa Nicole; Koch, Carolyn A.; Fiorilli, Diana; Bastian, Amy J.; Denckla, Martha Bridge; Miller, Michael I.; Mostofsky, Stewart H. – Journal of Occupational Therapy, Schools & Early Intervention, 2017
This study presents construct validity for a novel automated morphometric and kinematic handwriting assessment, including (1) convergent validity, establishing reliability of automated measures with traditional manual-derived Minnesota Handwriting Assessment (MHA), and (2) discriminant validity, establishing that the automated methods distinguish…

Mimeau, Catherine; Plourde, Vickie; Ouellet, Andrée-Anne; Dionne, Ginette – First Language, 2015
This study examined the validity and reliability of different measures of morphosyntactic complexity, including the Morphosyntactic Complexity Scale (MSCS), a novel adaptation of the Developmental Sentence Scoring, in French-speaking school-aged children. Seventy-three Quebec children from kindergarten to Grade 3 completed a definition task and a…

Casey, Beth M.; Lombardi, Caitlin McPherran; Pollock, Amanda; Fineman, Bonnie; Pezaris, Elizabeth – Journal of Cognition and Development, 2017
This study investigated longitudinal pathways leading from early spatial skills in first-grade girls to their fifth-grade analytical math reasoning abilities (N = 138). First-grade assessments included spatial skills, verbal skills, addition/subtraction skills, and frequency of choice of a decomposition or retrieval strategy on the…

WISC-IV Profiles Are Associated with Differences in Symptomatology and Outcome in Children with ADHD
Thaler, Nicholas S.; Bello, Danielle T.; Etcoff, Lewis M. – Journal of Attention Disorders, 2013
Objective: The current study investigated the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) cluster profiles of children with ADHD to examine the association between IQ profiles and diagnostic frequency, symptomatology, and outcome in this population. Method: Hierarchical cluster analysis was conducted on 189 children with a…

Rhemtulla, Mijke; Little, Todd D. – Journal of Cognition and Development, 2012
Data collection can be the most time- and cost-intensive part of developmental research. This article describes some long-proposed but little-used research designs that have the potential to maximize data quality (reliability and validity) while minimizing research cost. In "planned missing data designs", missing data are used…

Mrazik, Martin; Janzen, Troy M.; Dombrowski, Stefan C.; Barford, Sean W.; Krawchuk, Lindsey L. – Canadian Journal of School Psychology, 2012
A total of 19 graduate students enrolled in a graduate course conducted 6 consecutive administrations of the Wechsler Intelligence Scale for Children, 4th edition (WISC-IV, Canadian version). Test protocols were examined to obtain data describing the frequency of examiner errors, including administration and scoring errors. Results identified 511…

Curcic, Svjetlana; Johnstone, Robin S. – Computers in the Schools, 2016
This study examined the effects of an intervention in writing with digital interactive books. To improve the writing skills of seventh- and eighth-grade students with a learning disability in reading, we conducted a quasi-experimental study in which the students read interactive digital books (i-books), took notes, wrote summaries, and acted as…

Reanalysis of Wakefield and Carlson's data confirmed canonical correlations of .84 and .69, but analysis of redundancies revealed that only 34 percent of the total WISC subtest variance is redundant with the ITPA and 39 percent of the ITPA subtest variance is redundant with the WISC. (Author)

Peer reviewedWebster, Raymond E. – Psychology in the Schools, 1988
Examined temporal stability of Wechsler Intelligence Scale for Children-Revised (WISC-R) for adolescents (N=155) identified as either educable mentally retarded (EMR) or learning disabled (LD). Found three major scales of WISC-R to be more stable over three-year period for LD than for EMR group, while subtest scales for EMR group showed greater…

Peer reviewedOakland, Thomas; And Others – Journal of School Psychology, 1975
Interrater differences in scoring actual WISC protocols were determined for three different IQ levels. In general, differences among the 94 examiners tended to be within an acceptable range as established by the standard error of measurement; variance on two Verbal subtests occasionally exceeded their corresponding standard error of measurement.…

Designed to investigate the performance of American Indian youth on the "Wechsler Intelligence Scale for Children" (WISC) compared to the "Chicago Non-Verbal" (CNV) for the purpose of establishing validity and reliability of the measurement and appraisal tools, this study analyzed test data from 71 Indian youth (aged 11 to 15)…

SAFFORD, PHILIP L. – 1967
THE RELATIVE EFFECTIVENESS OF TASK SCORES VERSUS IQ AS PREDICTORS OF ACADEMIC ACHIEVEMENT WAS INVESTIGATED, AND THE CORRELATIONS BETWEEN TASK SCORES AND IQ RE-EXAMINED. SUBJECTS WERE 99 UPPER-MIDDLE CLASS ELEMENTARY SCHOOL CHILDREN WITH A MEAN STANFORD-BINET IQ OF 126 (SD EQUALS 19). THE INSTRUMENTS USED WERE DUNN'S OBJECT SORTING TASK (OST),…

Jensen, Arthur R. – 1975
The several statistical methods described for detecting test bias in terms of various internal features of a person's test performances and the test's construct validity can be applied to any groups in the population. But the evidence regarding groups other than U.S. blacks and whites is either lacking or is still too sketchy to permit any strong…
