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…

Cultural background can influence cognition, including executive functions (EFs), abilities that encompass skills responsible for self-regulation of thoughts and behavior. The seminal unity and diversity model of EFs proposes the existence, in adulthood, of at least three correlated but separable EF latent (shared variance in more than one…

The study examines the concurrent and longitudinal associations between ratings-based measures (parents, secondary caregivers, and observers) and performance-based measures of focused attention in toddlers aged 30 (n = 147), 36 (n = 127), and 42 months (n = 107). Parents and secondary caregivers rated focused attention behaviours using the…

This study explores Tibetan students' L2 and L3 motivational systems and their interactions based on the framework of the L2 Motivational Self-System proposed by Dörnyei. Five hundred fifty-two participants were invited to respond to a questionnaire regarding their Chinese (L2) and English (L3) motivational selves, learning experiences and…

The "About Me" Questionnaire (AMQ) has been used to measure components of social identity, academic self-concept and self-worth in children and adolescents in the United Kingdom and abroad. Studies have reported simple reliability statistics but a comprehensive assessment of the scale's psychometric properties has not been conducted.…

The Woodcock-Johnson-III cognitive in the adult time period (age 20 to 90 plus) was analyzed using exploratory bifactor analysis via the Schmid-Leiman orthogonalization procedure. The results of this study suggested possible overfactoring, a different factor structure from that posited in the Technical Manual and a lack of invariance across both…

Scientists and clinicians regularly use clinical screening tools for attention deficit/hyperactivity disorder (ADHD) to assess comorbidity without empirical evidence that these measures are valid in youth with autism spectrum disorder (ASD). We examined the prevalence of youth meeting ADHD criteria on the ADHD rating scale fourth edition…

The study of anthropomorphism in adults has received considerable interest with the development of the Individual Differences in Anthropomorphism Questionnaire (IDAQ; Waytz, Cacioppo, & Epley, 2010). Anthropomorphism in children--its development, correlates, and consequences--is also of significant interest, yet a comparable measure does not…

This study is focused on adapting the scales known as "Antisocial Beliefs and Attitudes Scales" ("ABAS") into Turkish version. The general aim of the study is to propound the Turkish version of the ABAS and to see if the scale functions in a similar fashion in Turkey in terms of its psychometric properties. The scales were…

The purpose of this study was to provide evidence of validity for the Mindful Attention Awareness Scale scores in an Argentine sample (Spanish-language version). Results indicated satisfactory psychometric properties (a one-factor structure, good item discrimination, high reliability, and significant correlations with additional measures). This…

In most ELT classes, the importance of grammar, how it should be taught or how much it should be integrated into language teaching are still matters of discussion. Considering this fact, learning teachers' attitudes towards teaching grammar is significantly valuable for researchers. This study thus aimed to design a scale that identifies teachers'…

Understanding the factor structure of autistic symptomatology is critical to the discovery and interpretation of causal mechanisms in autism spectrum disorder. We applied confirmatory factor analysis and assessment of measurement invariance to a large ("N" = 9635) accumulated collection of reports on quantitative autistic traits using…

With the aim of measuring preschool children temperament, EASI temperament Survey has been applied. Preschool teachers (N = 192), all female, rated a total of N = 3275 children (1612 girls and 1639 boys) with mean age M 4.368 (SD = 1.482) within age range between 7 months and 7.7 years. Validation for the instrument was run. Factor analysis on…

Traditional resources for ascertaining risk and protection for disengaged youth are often unsuitable, due to the stamina and skill required to complete them. Many of these tools assess risk without considering participants' potential for personal growth. The present study outlines the development and initial validation of a tool titled the…

The purpose of this study was to investigate the factorial structure and psychometric properties of the Spence Children's Anxiety Scale (SCAS) in a sample of 1,708 Spanish children aged between 8 and 12 years. The SCAS was demonstrated to have satisfactory internal consistency with the Spanish sample, and factor analysis confirmed the six-factor…
