There is limited recognition of self-determination concept in the Middle Eastern culture. Subsequently, there are no adapted measures of self-determination for Arabic adolescents with intellectual disability, learning disability, and multiple disabilities (intellectual disability and physical impairment). The purpose of this study was to examine…

The purpose of this article is to describe preliminary psychometric characteristics of a student self-report measure of self-determination, the "Self-Determination Inventory: Student Report" version (SDI-SR), designed for youth with and without disabilities. We administered the draft assessment to 311 youth and examined item functioning…

The factor structure of the CORE Phonics Survey was analyzed using a sample of 165 students in upper elementary school with specific learning disabilities. Confirmatory factor analysis was used to identify the hypothesized constructs of the CORE Phonics Survey and predictive validity of the CORE Phonics Survey to predict students' success in word…

Irish educational psychologists frequently use the Wechsler Intelligence Scale for Children-Fourth U.K. Edition (WISC-IV[superscript UK]) in clinical assessments of children with learning difficulties. Unfortunately, reliability and validity studies of the WISC-IV[superscript UK] have not yet been reported. This study examined the construct…

The purpose of this study was to identify subgroups of adult basic education (ABE) learners with different profiles of skills in the core reading components of decoding, word recognition, spelling, fluency, and comprehension. The analysis uses factor scores of those 5 reading components from on a prior investigation of the reliability and…

The Psychopathy Checklist-Revised (PCL-R) is the most widely used measure of psychopathy in forensic clinical practice, but the generalizability of the measure to offenders with intellectual disabilities (ID) has not been clearly established. This study examined the structural equivalence and scalar equivalence of the PCL-R in a sample of 185 male…

This study compared the underlying factors measured by a state standards-based grade 4 English-Language Arts (ELA) assessment given to several groups of students. The focus of the research was to gather evidence regarding whether or not the tests measured the same construct or constructs for students without disabilities who took the test under…

Based on the premises that strength-based assessment of children and adolescents is an important emerging area, and that additional tools for this purpose are needed, this study details development and validation efforts on a new strength-based assessment: the Social-Emotional Assets and Resilience Scale, parent form (SEARS-P). Following careful…

The purposes of this study were to investigate the reliability and construct validity of measures of reading component skills with a sample of adult basic education (ABE) learners, including both native and nonnative English speakers, and to describe the performance of those learners on the measures. Investigation of measures of reading components…

The construct validity of the Category Test (W. C. Halstead, 1947) was studied for 308 adults with heterogeneous cognitive dysfunction. Factor analysis indicated that Category subtests load on three factors distinct from intelligence: (1) symbol recognition/counting; (2) spatial position reasoning; (3) and proportional reasoning. Clinical…

The psychometric properties of the Hopelessness Scale for Children (A. Kazdin et al., 1983) were examined for children and adolescents with mental retardation or a learning disability. Analyses of scores from 261 students shows a factor structure almost identical to the original structure and scale scores of adequate validity. (SLD)

This study evaluated the construct validity of the Wechsler Intelligence Scale for Children, Third Edition (WISC-III) with children (ages 8 to 13) having learning disabilities who were either Hispanic (N=120) or Non-Hispanic white (N=120). Factor analyses found that the WISC III has a three factor structure consisting of verbal comprehension,…

Analysis of Kaufman Assessment Battery for Children (K-ABC) Sequential and Simultaneous Processing scores of 94 children (ages 6-12) with learning disabilities produced factor patterns generally supportive of the traditional K-ABC Mental Processing structure with the exception of Spatial Memory. The sample exhibited relative processing strengths…

The Windward Rating Scale (WRS), a locally-developed teacher rating scale of student behavior, was evaluated for potential use as a screening measure. Pre-certification ratings of 720 learning disabled students and non-special education students in grades K-6 were analyzed. Psychometric properties and diagnostic efficiency of the WRS were…
