CDKL5 deficiency disorder (CDD) results in early-onset epilepsy and lifelong cognitive and motor impairments. With no validated measure for communication in CDD, this study evaluated the psychometric properties of the Communication and Symbolic Behavior Scales-Developmental Profile Infant Toddler Checklist (CSBS-DP ITC). Caregivers (n = 150;…

The Classroom Learning Activities Checklist (CLAC) is a brief classroom observation measure that assesses task-oriented and self-regulated learning in early childhood environments. We assessed the tool's dimensionality and validity in predicting prekindergarten (PreK) learning gains. The study sample is from the Midwest Child-Parent Center (MCPC)…

This study aimed to address the need for a comprehensive assessment tool to evaluate the mathematical abilities of first-grade students through cognitive diagnostic assessment (CDA). The primary challenge involved in this endeavor was to delineate the specific cognitive skills and sub-skills pertinent to first-grade mathematics (FG-M) and to…

The Modified Checklist for Autism in Toddlers (M-CHAT) is a screening questionnaire for Autism Spectrum Disorder (ASD). Previous findings have confirmed the M-CHAT's sensitivity and specificity across several cultures, yet few studies have considered M-CHAT scores as a distributed trait in a sample of typical infants. The current study examined…

Communication skills are fundamental in healthcare, but assessing them among medical students presents challenges. In the Indian context, the lack of a specific assessment tool further compounds the issue. Thus this study aimed to develop and validate an observation-based communication skills checklist tailored to Phase I Bachelor of Medicine and…

Students with autism spectrum disorders (ASDs) in Saudi Arabia are provided with the educational services they need in their local schools, but a standardized checklist is needed to measure the level of progress and the benefits acquired through the educational programs. This study aimed to standardize a version of Saudi performance norms on the…

Psychiatric disorders in individuals with co-occurring autism spectrum disorders (ASD) and intellectual disability (ID) are common, but diagnosis presents many challenges. The Psychopathology in Autism checklist (PAC) is among the very few instruments specifically developed for this group of individuals. The psychometric properties of the PAC…

Background: While empirical testing of many of the interRAI Child and Youth Mental Health (ChYMH) assessment scales have been found to be reliable and valid across both child and adult samples, other scales have yet to be psychometrically evaluated within child populations. Objective: The current study evaluates the psychometric properties of the…

The Hellenic WISC-III (Wechsler, 1997) is currently the only standardized and officially published tool for the assessment of the intelligence of children and adolescents in Greece. The test is also used with caution in Cyprus, among Greek speakers, but no specific norms exist for use in this country. The purpose of this study was to provide…

The prevalence of bullying has increased over the past decade and is a public health concern. Existing measures of bullying lack breadth and/or psychometric support, which may inaccurately represent current rates of bullying. The purpose of this study was to develop and validate a psychometrically sound measure, the Multidimensional Bullying…

This article presents information on the development and initial validation of the 16-item Response to Intervention (RTI) Beliefs Scale. The scale is designed to measure the extent to which educators working in schools hold beliefs consistent with the tenets of RTI. The authors administered the instrument to 2,430 educators in 62 elementary…

This study assessed the reliability and criterion-related validity of teacher ratings on the Adapted Skillstreaming Checklist for a sample of 133 children, aged 6-11 years, with autism spectrum disorder (without intellectual disability). Internal consistency for the total sample was 0.93. For a subsample, test-retest reliability was very good (r =…

In empirical applied linguistics research it is essential that the key variables are operationalized in a valid and reliable way, and that the scores are treated appropriately, allowing for a proper testing of the hypotheses under investigation. The current article addresses several theoretical and practical issues regarding the use of measurement…

Several studies have concluded that scores from Hare's (2003) Psychopathy Checklist--Revised (PCL-R) predict reoffense among sexual offenders, but most of those studies examined the predictive validity of scores from trained research staff, not clinicians in the field scoring the measure as part of actual forensic assessments. Therefore, we…

We report findings of a convergent validity study examining the internalizing subscale (SRSS-I6) of the Student Risk Screening Scale for Internalizing and Externalizing (SRSS-IE) with the internalizing subscale of the Teacher Report Form (TRF; Achenbach, 1991). Participants included 227 sixth- through 12th-grade students from nine schools across…
