The present investigation explored the psychometric validity of the five-item Gratitude Questionnaire (GQ-5) using a construct validation approach. Concerning within-network construct validity, results of item response theory (IRT) analysis via graded response model (GRM) showed that this scale could not discriminate individuals who score high in…

Objective: The factor structure of the Grit-S is the subject of much debate. The purpose of this study was to examine the factor structure of the Grit-S and validate its psychometric properties among racially/ethically minoritized adolescents using Item Response Theory (IRT). Method: Data were collected from 651 racially/ethnically minoritized…

The construct validity of the International Cognitive Ability Resource (ICAR) has yet to be investigated using a gold-standard individually administered intelligence battery. The present study used a convenience sample of 97 students to examine the respective relations between the ICAR16 and overall intelligence (g) and the Cattell-Horn-Carroll…

The current study examined the psychometric properties and correlates of three measures assessing individual differences in mattering among people from Palestine assessed in January, 2024. This study uniquely considers mattering as a resource and feelings of not mattering as a risk factor among people experiencing traumatizing life circumstances.…

Using an established global academic interest scale, academic interest dimensions of undergraduate (n = 326) and graduate (n = 401) students were compared. The four-factor structure, consisting of passion for learning, confidence in the future, career aspiration, and self-expression, held for both student groups. However, the item scores and mean…

The Big Three Perfectionism Scale (BTPS) was created to integrate different aspects of perfectionism, including the newly conceptualized concept of narcissistic perfectionism. The goal of our two studies (N = 1341) was to examine the psychometric properties of the Polish adaptation of the BTPS, supporting the validity and portability of the…

General self-efficacy represents the global sense of personal capability across various situations and tasks. The aim of the present study was to develop and validate a single-item general self-efficacy scale which balances practical demands and psychometric concerns. The psychometric properties of the proposed Single-Item General Self-Efficacy…

The Woodcock-Johnson Tests of Achievement, Fourth Edition (WJ IV ACH) is purported to align with Cattell-Horn-Carroll (CHC) theory and offers upward of 20 scores within its interpretive and scoring system. The Technical Manual does not furnish validity evidence for the scores reported by the scoring system, suggesting that evidentiary support may…

The current study aimed to develop a measure of anticipated teacher-student relationship quality to be used with preservice teacher populations that is operationally similar to a measure commonly used with inservice teachers (i.e., short-form of the Student-Teacher Relationship Scale). To date, teacher-student relationship quality has been a…

The impact of teachers' beliefs on the implementation and effectiveness of Social and Emotional Learning (SEL) programs underscores the essential need for reliable measures of these beliefs.
