Purpose: Wellbeing refers to a person's overall happiness and satisfaction with life. Wellbeing for people with Intellectual and Developmental Disabilities (I/DD) and their families is historically significantly lower compared to the general population. It is important in the context of behavioral health treatment to not only measure the…

The Eyberg Child Behavior Inventory (ECBI) is a frequently used measure to assess interfering behaviors in children and psychometric properties have recently been examined in children with autism spectrum disorder (ASD). There is a need to confirm the identified factors and examine the factor structure in a racially/ethnically diverse,…

From the perspective of positive psychology, the study and measurement of subjective well-being has popularized a growing interest towards variables such as affective perception. In an attempt to explain and evaluate the affective structure in positive terms (PA) and negative terms (NA), PANASN affect scale (Sandín, 2003) constitutes the version…

This study aimed to develop a comprehensive tool to assess underachievement in gifted students, incorporating input from parents, teachers, and students themselves. A total of 285 participants, including 95 gifted students, their parents, and teachers, were involved in the study. The results have revealed a four-factor structure for the Gifted…

The Autism Impact Measure is a caregiver-reported, behaviorally based measure designed to assess both frequency and functional impact of core ASD symptoms in children. This study used confirmatory factor analysis to determine if the factor structure of the AIM (Repetitive Behavior, Communication, Atypical Behavior, Social Reciprocity, and Peer…

This research aims to develop an instrument for the evaluation of impulsivity traits in children and to examine the psychometric features of the developed scale. The process of developing the scale involved three main phases: namely, item generation, evaluation of content validity, and analysis of psychometric properties. The study sample…

Purpose: To examine the factor structure and measurement invariance of the Körperkoordinations Test Für Kinder (KTK) and covariates of motor competence in a sample of Iranian children aged 5-14 years. Methods: Participants were children aged 5-14 years (N = 432, 61% boys). Age, sex, and body mass index were collected. Confirmatory factor analysis…

The aim of the current study was to validate the self-report version of the Rosenberg Self-Esteem Scale (RSES; Rosenberg, 1965) structure in a sample of Greek primary school students. The study was based on the original one-factor model suggested by the scale's author, as well as on the two-factor correlated model of positive and negative items.…

Sense of coherence (SOC) is a relevant contributor and predictor of the individuals' mental and physical health. There are a number of studies about SOC, but only two validation articles of the sense of coherence scale (SOCS) were found on adolescents and none on children. The aim of this research was to validate the SOC scale in youth under 18.…

Aim: To examine the latent structure of the "Test of Gross Motor Development--Third Edition" (TGMD-3) with a bifactor modeling approach. In addition, the study examines the dimensionality and model-based reliability of general and specific contributions of the test's subscales and measurement invariance of the TGMD-3. Methods: A…

This study described the development of the "Social Skills Improvement System Social Emotional Learning Edition Rating Forms" (SSIS SEL RF) for teachers, parents, and students. This new multirater assessment is a reconfiguration of the SSIS Rating Scales items inspired by the CASEL Social Emotional Competency framework. The internal…

Restricted repetitive behaviors (RRBs) are a core feature of autism spectrum disorders (ASD) and further occur in intellectual disability (ID), mental disorders (MD), and in typically developed people (TD). There is a need of a valid and reliable measure to record RRBs as transdiagnostic symptom, which captures RRBs heterogeneity and evaluates…

The Test of Emotion Comprehension (TEC) has been used extensively to investigate children's understanding of emotion. The present study aimed at investigating the TEC's factorial structure, its measurement invariance across age and gender, and defining age-referred TEC scores, in a large sample of 1,478 children (755 males, 723 females) aged…

The factorial structure of the WISC-IV for 859 Spanish children diagnosed with ADHD was examined. A bifactor model with the four factors first identified by Wechsler (2003a) was the best fit to the data. The Coding and Symbol Search subtests were particularly poor measures of "g" but relatively strong measures of the Processing Speed…

Confirmatory factor analysis (CFA) and exploratory and factor analysis (EFA) aimed to determine the optimum Autism Spectrum Quotient--Children (AQ-Child) model. Initial CFA of parent ratings of the AQ-Child for 404 clinic-referred children with ADHD, aged between 4 and 11 years, revealed mixed/moderate support for the implied AQ-Child five-factor…
