The patient health questionnaire-9 (PHQ-9) is widely utilized in assessing individuals' depression levels. Nevertheless, research regarding its factor structure and measurement invariance remains inadequate. The aim of this study was to delve into the factor structure of the PHQ-9 and to further investigate its measurement invariance across gender…

The present study aims to validate the Flourishing Scale (FS) in a convenience sample of 233 special education teachers. The FS's psychometric properties were investigated using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). EFA had a one-factor solution that explained 49.9% of the variance, a Cronbach's alpha internal…

Academic Self-Efficacy for Self-Regulated Learning (ASE for SRL) represents individuals' belief in their abilities to regulate and organize their learning to achieve academic outcomes, and it is crucial for motivation and students' well-being. This study, conducted on a nationally representative sample of 26,564 10th grade Italian students (50.1%…

Students with learning disabilities (LD) represent a vulnerable population and are at higher risk for social and emotional challenges compared to their peers without LD. A strengths-based orientation is recommended to encourage building resilience factors to counteract the negative effects of LD over the lifespan. To identify areas of strength and…

Intervention researchers often use curriculum-based measurement of reading fluency (CBM-R) with a brief experimental analysis (BEA) to identify an effective intervention for individual students. The current study synthesized data from 22 studies that used CBM-R data within a BEA by computing the standard error of measure (SEM) for the median data…

This study examined the exchangeability of total scores (i.e., intelligent quotients [IQs]) from three brief intelligence tests. Tests were administered to 36 children with intellectual giftedness, scored live by one set of primary examiners and later scored by a secondary examiner. For each student, six IQs were calculated, and all 216 values…

Reading fluency is a critical yet commonly neglected component of early reading instruction. For the large percentage of English language learners (ELLs) who are struggling with or at risk for reading difficulties, there is insufficient research available to help educators implement time-efficient interventions with these students. Using an…

The interpretation of cognitive test scores often leads to decisions concerning the diagnosis, educational placement, and types of interventions used for children. Therefore, it is important that practitioners administer and score cognitive tests without error. This study assesses the frequency and types of examiner errors that occur during the…

Evidence-based practice approaches to interventions has come of age and promises to provide a new standard of excellence for school psychologists. This article describes several definitions of evidence-based practice and the problems associated with traditional statistical analyses that rely on rejection of the null hypothesis for the…

Examined 60 Wechsler Intelligence Scale for Children-Third Education (WISC-III) protocols administered by graduate students in training to obtain preliminary data on the frequency and types of administration and scoring errors that examiners commit. The five most frequent errors included failure to query, failure to record response verbatim,…

Examines various procedures for constructing confidence intervals that have been suggested in measurement texts in relation to their approximation to the most accurate procedure that uses the estimated true score as the center of the confidence interval and the standard error of estimate to determine width. (Author/ABL)

Analyzed for examiner errors 55 Wide Range Achievement Test-Revised (WRAT-R) protocols completed by 9 practitioners for metropolitan school district. All practitioners made errors, which occurred on 95 percent of protocols and averaged 3.0 errors per protocol. Most frequent errors included failures to obtain correct ceiling or basal, and failures…

Extensive evidence exists demonstrating the utility of Curriculum-Based Measurement in reading (R-CBM) for progress-monitoring purposes; however, most studies have evaluated R-CBM from a traditional psychometric perspective, which allows for variability in individual student's data that is not a function of increased skills (i.e., measurement…

Clinical psychology graduate students (N=14) administered Wechsler Intelligence Scale for Children-Revised. Found numerous scoring and mechanical errors that influenced full-scale intelligence quotient scores on two-thirds of protocols. Particularly prone to error were Verbal subtests of Vocabulary, Comprehension, and Similarities. Noted specific…

Studied the effects of experience in administration and scoring of the Wechsler Intelligence Scale for Children (Revised) on types of examiner errors. Results showed total score and administrative error rates dropped significantly with experience and feedback, but response scoring errors, mathematical errors, and IQ errors were not reduced…
