This dissertation presents an innovative approach to examining the keying method, wording method, and construct validity on psychometric instruments. By employing a mixed methods explanatory sequential design, the effects of keying and wording in two psychometric assessments were examined and validated. Those two self-report psychometric…

This study was conducted to develop an instrument with good psychometric properties to measure primary school students' attitudes towards mathematics. For this purpose, the screening model was utilised in the research. The form was prepared in the form of a five-point Likert scale (Very Unhappy, Unhappy, Neither Happy nor Unhappy, Happy, Very…

Anxiety, depression, and suicidality are major concerns among college students, though less is known about these constructs in autistic college students. Given the rising number of autistic individuals entering post-secondary education, adequate measurement and diagnosis of anxiety, depression, and suicidality is necessary to provide clinical care…

Student understanding of climate change is an active and growing area of research, but little research has documented undergraduate students' knowledge about the biotic impacts of climate change. Here, we address this literature gap by presenting the Inventory of Biotic Climate Literacy (IBCL), a concept inventory developed to assess undergraduate…

The development of a teacher identity (TI) profoundly impacts teacher education program graduates' career intention and teaching practices. Existing studies on pre-service physical education teachers' teacher identity (PPET-TI) have used qualitative methods to focus on the dynamic and reflective features of TI. Quantitative studies that help…

Possession of hope and meaning in life is critical for mental health, especially in times of adversity.

The psychometric integrity of a curriculum-based measure to screen for academic giftedness (Monitoring Instructional Responsiveness: Reading [MIR:R]) was evaluated by examining its ceiling, item gradient, and predictive capacity using 460 fourth grade students. Eighty fourth graders (17.39%) scored one standard deviation above the MIR:R mean. Ten…

Writing motivation is a multidimensional construct that has been demonstrated to be of great importance in writing performance and growth. Yet, much of the extant research has failed to examine the nuances of the various dimensions of writing motivation--in particular, task competency beliefs--and has neglected to investigate how the various…

The current study investigated Student-Teacher Relationship Measure (STRM) psychometric properties using Rasch analysis in a sample of middle school female students (N = 995). Rasch Principal Components Analysis revealed psychometric support of two subscales (i.e., Academic and Social Relations). Summary statistics showed good psychometric…

Hope is a defining characteristic of well-being, and research points to the positive contribution of hope to life adjustment (Snyder, Lehman, Kluck, & Monssan, 2006). Harris developed an initial version of an individual-differences measure of hope, the Trait Hope Scale (THS). Snyder, Harris, and colleagues (1991) further developed the THS by…

Background: The Developmental Behaviour Checklist (DBC) is an established, internationally used questionnaire for assessing behavioural and emotional problems among young people with developmental or intellectual disabilities (ID).
