Validity is broadly defined as how well something measures what it's supposed to measure. The reliability and validity of scores from assessments are two concepts that are closely knit together and feed into each other.

Background: "How do I perceive my own body?" is a central question during adolescence, which addresses the subjective assessment of body image, called Body Esteem.

Research Findings: The Children's Social Understanding Scale (CSUS) assesses young children's theory of mind (ToM). The current study adapted the parent version of the CSUS-short form to Turkish and examined its utility, for the first time, as an assessment tool for teachers. The associations of parent and teacher reports of the CSUS-short form…

The present study aimed to adapt the Teacher Self-Efficacy Scale (TSES) developed by Schwarzer et al. (1999) into Italian and to test its validity and reliability. In a group of teachers (N = 683; 83% female), the factor structure (Confirmatory Factor Analyses), construct validity (latent relations with burnout variables), measurement invariance…

In recent years, research has focused on the factor structure of the Teacher Sense of Efficacy Scale (TSES), and the significant effects of teachers' self-efficacy on both teachers' outcomes (teachers' performance, enjoyment of teaching, and commitment to teach), and students' outcomes (student learning achievements, motivation, and own sense of…

This study aims to develop a valid and reliable assessment tool for the assessment of safety skills of individuals with intellectual disabilities, examine the effectiveness of the Safety Skills Instruction Program (SSIP) in teaching safety skills to these individuals, determine the preservation of skills after instruction by observation, and…

Low cost, non-invasive instruments for the identification of high academic potential in early childhood education and care are scarce, and the complexity of cognitive development indicates that combinations of screening instruments are needed. This study investigates the reliability and validity of three instruments (individually and in…

We aimed to refine the previously proposed antisocial subscale for the Dimensional Clinical Personality Inventory 2 (IDCP-ASPD). The sample involved 628 Brazilian adults between 18 and 81 years old. We administered the revised ASPD subscale (IDCP-ASPD-R), the Affective and Cognitive Measure of Empathy (ACME), the Crime and Analogous Behavior Scale…

Early childhood educators (ECEs) are highly influential role models in the childcare setting with respect to encouraging physical activity and outdoor play, and minimizing sedentary behavior among children in childcare. Measuring ECEs' behavioral intention (BI) and perceived behavioral control (PBC) is one way to monitor their determination and…

Background: The Personal Outcomes Scale is a measurement tool to examine quality of life among persons with intellectual disability. This paper addressed the validity and reliability of the Japanese version of the scale using both self-reports and reports of others. Method: Data were collected from 128 people with intellectual disability (90 men…

School algebra serves as the language of mathematics and a foundational subject for learning advanced mathematics courses. This makes developing learners' proficiency in algebra the most desirable instructional goal of school mathematics. Despite having such importance emphasis, however, studies indicate that the vast majority of learners are…

Background: Direct support professionals' (DSPs') attitudes toward nutrition are important for supporting a healthy lifestyle of persons with intellectual disabilities. However, there are no instruments to measure it. The aim of this study was to compose a questionnaire and determine its internal validity. Method: The previously validated Health…
