In order to make appropriate educational recommendations, psychologists must understand how cognitive test scores influence specific academic outcomes for students of different ability levels. We used data from the WISC-V and WIAT-III (N = 181) to examine which WISC-V Index scores predicted children's specific and broad academic skills and if…

Introduction: There are different tests that assess attention and can help to make a differential diagnosis between ADHD and Learning Disabilities (LD), but there appears to be little research on the convergent and predictive validity of these tests. The aim of this study was to analyze the convergent validity of the EMAV, Caras, d2, AGL, CPT-II…

Social skills and academic competence are key factors influencing children's development and functioning across early childhood and through adolescence. There is a great need to understand the longitudinal patterns of growth in social and academic skills in order to further inform intervention, particularly for at-risk groups such as individuals…

Mothers of individuals with Prader-Willi syndrome (PWS) often experience numerous stressors, even when compared to mothers of children with other intellectual and developmental disabilities. Despite this, these mothers show great variability in self-reported life satisfaction. Using data from a longitudinal study of individuals with PWS and their…

This study is an examination of the incremental validity of Cattell-Horn-Carroll (CHC) broad clusters from the Woodcock-Johnson III Tests of Cognitive Abilities (WJ III COG) for predicting scores on the Woodcock-Johnson III Tests of Achievement (WJ III ACH). The participants were children and adolescents, ages 6-18 (n = 4,722), drawn from the WJ…

This study examines the application of the Simple View of Reading (SVR), a reading comprehension theory focusing on word recognition and linguistic comprehension, to English Language Learners' (ELLs') English reading development. This study examines the concurrent and predictive validity of two components of the SVR, oral language and word-level…

Socioecological theory suggests that there are a range of influences that affect the physical activity levels of children, including parents' perceptions of the neighborhood. A questionnaire instrument to quantify parental neighborhood perceptions was developed for the Location of Children's Activity in Their Environment study as a potential…

Measurement invariance (MI) is a property of measurement that is often implicitly assumed, but in many cases, not tested. When the assumption of MI is tested, it generally involves determining if the measurement holds longitudinally or cross-culturally. A growing literature shows that other groupings can, and should, be considered as well.…

This study explored the association between reading self-belief and reading achievement among a representative sample of nine year old children in the Republic of Ireland. Results from analysis of variance and simple effects analysis showed a positive linear association between reading achievement and "attitude to reading." The…

Given the disadvantaged position of working-class children in the education system, it is important to understand how parents and families might support their children to succeed academically. This paper reports on 35 case studies that were conducted as part of the Effective Provision of Pre-School, Primary and Secondary Education (EPPSE 3-16)…

Analyses were conducted, using the Early Childhood Longitudinal Study, Kindergarten Class (ECLS-K) database, to compare teachers' judgment of reading skill with direct measures of reading performance for kindergarten, first grade, and third grade students. Teacher judgments of kindergarten students' reading skill significantly predicted first and…

Aim: The objective of this study was to investigate which attentional components are of predictive utility in differentiating children with attention-deficit-hyperactivity disorder, combined type (ADHD-C) from their peers without ADHD. Methods: Thirty-four children participated in the study: 17 males with ADHD-C (mean age 10y 4mo, SD 1y 9mo) and…

Tests of the validity of the Wechsler Intelligence Scale for Children Third Edition Arithmetic, Coding, Information, and Digit Span (ACID) profile among 612 students with learning disabilities revealed that the ACID profile does not efficiently separate children with disabilities from those without disabilities. No ACID cutting score significantly…

Examined 128 children for contributions of biomedical risk conditions, SES, and HOME scores to prediction of intelligence, and association of extreme scores on HOME and SES to intelligence-test performance. Found home environment was the most important predictor of intelligence at all ages, with SES showing a smaller effect beginning at age 5.…

Examined the relationships of reading and math achievement with intelligence and adaptive behavior in Anglo, Black, and Mexican American children (N=345). The variance accounted for by the full model (race, sex, age, and socioeconomic status) was significant for reading and math. Variance associated with race and socioeconomic status was…
