Objective: This study examines the validity of the ASRS-5 as a new screening tool for ADHD and evaluates its proposed screening cut-off in a general population context. Method: A nationally representative sample of 2,002 individuals aged 18 to 80 years was surveyed using the ASRS-5, with complete data obtained from 714 participants. Psychometric…

This study aimed to adapt the COVID-19 Stress Scales (CSS) into Turkish and provide evidence for construct validity. For this purpose, firstly, Confirmatory factor analysis (CFA) was applied for the 5-factor model obtained during the development of CSS and the theoretically expected 6-factor model with total of 546 respondents. The findings…

The Expectancy-Value model has been extensively used to understand students' achievement motivation. However, recent studies propose the inclusion of cost as a separate construct from values, leading to the development of the Expectancy-Value-Cost model. This study aimed to adapt Kosovich et al.'s ("The Journal of Early Adolescence", 35,…

The purpose of this study is to develop Education Value Perception Scale (EVPS) based on Bronfenbrenner's Ecological Theory and to investigate its psychometric properties according to Classical Test Theory (CTT) and Item Response Theory (IRT). The data were collected from 2872 secondary school students by stratified purposeful sampling method.…

Metacognition is a powerful predictor for learning performance, and for problem-solving. But how metacognition works for cognitive strategies and learning performance is not clear. The present study was designed to explore how metacognition affected the cognition (learning strategies and problem solving strategies) and different kinds of learning…

The study investigates consequences of eliminating items showing gender-specific differential item functioning (DIF) on the psychometric structure of a standard RIASEC interest inventory. Holland's hexagonal model was tested for structural invariance using a confirmatory methodological approach (confirmatory factor analysis and randomization…

Key concerns about the psychometric properties of the 25-item version of the Strengths and Difficulties Questionnaire (SDQ) have consistently been raised in the literature. The present study aimed at examining the meaningfulness of an alternative model to the SDQ in which 7 problematic items are excluded. French-speaking parents of 262 boys and…

This study attempted to develop valid and reliable Capstone Project Attitude Scales (CPAS). Among the scales reviewed, the Modified Fennema-Shermann Mathematics Attitude Scales was adapted in the construction of the CPAS. Usefulness, Confidence, and Gender View were the three subscales of the CPAS. Four hundred sixty-three students answered the…

Social-emotional health influences youth developmental trajectories and there is growing interest among educators to measure the social-emotional health of the students they serve. This study replicated the psychometric characteristics of the Social Emotional Health Survey (SEHS) with a diverse sample of high school students (Grades 9-12; N =…

This study examined the psychometric properties of the Personal Well-being Index for Adults (PWI-A), a measure of subjective well-being. The study used data from 533 high-ability American college students: honors students and participants in an early college entrance program. In earlier studies using the PWI-A, the instrument appeared to show…

The psychometric properties of the Revised Children's Manifest Anxiety Scale-Second Edition (RCMAS-2) were examined in a sample of 1,003 U.S. elementary and secondary students in Grades 2 to 12. Confirmatory factor analyses (CFAs) were performed comparing the five-factor (target) model consisting of three anxiety (Physiological Anxiety, Social…

Online learning constitutes the most popular distance-learning method, with flexibility, accessibility, visibility, manageability and availability as its core features. However, current research indicates that its efficacy is not consistent across all learners. This study aimed to modify and extend the factors of the Technology Acceptance Model…

Blended learning combines multiple delivery media that are designed to complement each other and promote learning and application-learned behavior (Smith & Dillon, 1999). This article reports on a study conducted in the College of Information Technology to evaluate levels of student' satisfaction with blended learning. The particular blend of…

Lahey and Waldman (2003, 2005) proposed a model in which three dispositions--sympathetic response to others; negative emotional response to threat, frustration, and loss; and positive response to novelty and risk--transact with the environment to influence risk for conduct disorder (CD). To test this model, the Child and Adolescent Dispositions…

Early childhood social-emotional assessment has traditionally focused on risk factors or psychopathology, and has less frequently examined protective factors that may serve to promote positive developmental outcomes for children. To advance conceptual models that include protective factors as key explanatory constructs, there is a need for…
