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…

Supporting teachers professionally, both in their teaching skills and the inclusion of technology, is one of the few direct interventions to help them grow. Currently, few instruments assessing these perceptions exist, and evidence on their validity is sparse. Hence, this paper presents the development and validation of an instrument assessing…

Research Findings: The Classroom Assessment Scoring System Toddler (CLASS-T) is one of the most commonly used measures to assess the quality of teacher-child interactions in toddler classrooms. Despite widespread use of the CLASS-T, few studies have examined the factor structure of the CLASS-T for use in Early Head Start (EHS) and subsidized child…

Autism spectrum disorders are diagnosed globally, but recognition, interpretation and reporting may vary across cultures. To compare autism across cultures it is important to investigate whether the tools used are conceptually equivalent across cultures. This study evaluated the factor structure of the parent-reported Autism Spectrum Quotient…

The current study aimed to test the factorial structure and psychometric properties of a parent version of the Multidimensional School Climate Questionnaire (MSCQ), a multi-informant and multidimensional measure of school climate recently developed and validated in Italian for a student version, by also providing evidence of measurement invariance…

Item factor analysis (IFA), also known as Multidimensional Item Response Theory (MIRT), is a general framework for specifying the functional relationship between a respondent's multiple latent traits and their response to assessment items. The key element in MIRT is the relationship between the items and the latent traits, so-called item factor…

The Family Outcomes Survey--Revised (FOS-R) measures family outcomes of services for young children with disabilities or developmental delays, and it can be used to investigate change in outcome achievement over time. To confirm the validity of FOS-R change scores, it must be established that the FOS-R measures the same construct over time; if so,…

Emotional well-being, social inclusion, and academic self-concept are crucial for students' academic and socio-emotional development, and are seen as key factors for successful inclusion. Considering this relevance, the Perception of Inclusion Questionnaire (PIQ) has been developed as a short screening instrument to assess these three aspects--not…

This paper reports on the development and validation of the classroom assessment (CA) for self-regulated learning (SRL) Questionnaire (CASRLQ), a questionnaire intended to measure to what extent CA practices are SRL supportive. The original CASRLQ, consisting of 32 items to represent five SRL-supportive CA dimensions, was constructed and…

Background: The Evidence-Based Practice Attitudes Scale (EBPAS) is widely used in implementation research, but it has not been adapted and validated for use among general education teachers, who are most likely to deliver evidence-based prevention programs in schools, the most common setting where youth access social, emotional, and behavioral…

Background: The ability to navigate obstacles and embrace iteration following failure is a hallmark of a scientific disposition and is hypothesized to increase students' persistence in science, technology, engineering, and mathematics (STEM). However, this ability is often not explicitly explored or addressed by STEM instructors. Recent collective…

According to the literature, the use of the Berkeley Puppet Interview (BPI) to measure Big Five personality traits in children provides reliable and valid scores. However, the implementation of the BPI could be costly, especially when working with large sample sizes. Big Five self-reports were collected from 1118 Mexican children aged 7-8 years…

Prior studies investigating restricted and repetitive behavior (RRB) subtypes within autism spectrum disorder (ASD) have found varied factor structures for symptom groupings, in part, due to variation in symptom measurement and broad sample age ranges. This study examined RRBs among 827 preschool-age children, ages 35 to 71 months, through an…

The Children's Sleep Habits Questionnaire (CSHQ) is often used to assess sleep in children with autism spectrum disorder (ASD), but little is known about its factor structure in younger children with ASD. We evaluated alternative factor structures and measurement invariance for CSHQ items in 2- to 4-year-olds with ASD or typical development (TD).…

Evaluation of child-friendly school (CFS) policies is essential to determine the achievements of school efforts in reducing violence cases. This research aims to proving the reliability and validity of CFS policy evaluation instruments in elementary schools with different locations. This investigation uses the Context Input Process Product (CIPP)…
