This study reports the evaluation of four positive psychology assessments for use in clinical, education, and research settings with individuals in Ghana, Africa. The analyses attempted to identify validity evidence for internal structure and relationships with related variables for the Satisfaction with Life Scale (SLS; Diener et al.…

The aim of the present study was to determine the factor structure of the Positive Life Assets Scale (PLAS), a new measure to identify both internal and external life assets among high school students in Thailand, and to further examine the usefulness of the PLAS for a comprehensive, developmental, and strengths-based school and community…

This study explored the factor structure and psychometric properties of the Perceived Sense of School Membership (PSSM-18) Scale in two samples of South African adolescents. Principal components analysis (n = 1,052; males = 50.86%, M[subscript age] = 14.89, SD = 1.68) supported the retention of 15 items across a revised, three-factor structure of…

The implementation of data-driven decision-making practices (DDDM) is a key component of contemporary teachers' professional practice. As such, the measurement of DDDM and related constructs is important for multiple purposes in both research and practice (e.g., identifying teacher needs around DDDM, and monitoring teacher change in response to…

The purpose of this study is to further enhance the existing reliability and validity evidence related to the School Implementation Scale (SIS) and its use for evaluating the implementation of different integrated academic and behavior tiered Response-To-Intervention (RTI) models. Previous methodology conducted for validation of the instrument has…

Basic motor competencies (in German: Motorische Basiskompetenzen; MOBAK) are motor performance dispositions formulated as minimum standards that empower children to participate in the culture of human movement. In opposition to movement-specific and process-oriented fundamental movement skills assessing the quality of movement execution, basic…

This study aims to explore the construct structure of the Turkish version of the "Myself-As-A-Learner Scale" ("MALS"), which was designed to measure academic self-concept. A translated version of MALS was administered to 483 participants (mean age = 14.31, SD = 2.08) in six different cities across Turkey. An exploratory factor…

Purpose: A new measure of sportspersonship, which differentiates between compliance and principled approaches, was developed and initially validated in 3 studies. Method: Study 1 developed items, assessed content validity, and proposed a model. Study 2 tested the factorial validity of the model on an independent sample. Study 3 further tested the…

Numerous well-validated academic progress monitoring tools are used in schools, but there are fewer behavioral progress monitoring measures available. Some brief behavior rating scales have been shown to be effective in monitoring students' progress, but most focus only on students' social skills and do not address critical academic-related…

The Colorado Learning Attitudes about Science Survey (CLASS) is a widely used instrument designed to measure student attitudes toward physics and learning physics. Previous research revealed a fairly complex factor structure. In this study, exploratory and confirmatory factor analyses were conducted on data from an undergraduate introductory…

Numerous well validated academic progress monitoring tools are used in schools, but there are fewer behavioral progress monitoring measures available. Some brief behavior rating scales have been shown to be effective in monitoring students' progress, but most focus only on students' social skills and do not address critical academic-related…

Objective: This article examines the measurement invariance of "Family, School, and Peer Influence on Volunteerism Scale" (FSPV) across genders using the mean and covariance structure analysis approach. Method: A total of 2,845 Chinese high school adolescents aged 11 to 15 years completed the FSPV scale. Results: Results of the…

This study explored motivation and engagement among North American (the United States and Canada; n = 1,540), U.K. (n = 1,558), Australian (n = 2,283), and Chinese (n = 3,753) secondary school students. Motivation and engagement were assessed via students' responses to the Motivation and Engagement Scale-High School (MES-HS). Confirmatory factor…

Purpose: To examine the factorial structure of the "Coping Strategy Questionnaire"-24 (CSQ-24) in a sample of Canadians with chronic musculoskeletal pain. Method: The sample included 171 workers' compensation clients (50.9% men) recruited from outpatient rehabilitation facilities in Canada. Mean age of participants was 42.45 years (SD =…

The validity of the Student-Teacher Relationship Scale (STRS) was examined in a preschool community sample (N = 925) using confirmatory factor analysis (CFA). Factorial invariance across genders was also investigated as was concurrent and discriminant validity. Indicators of validity were teacher-rated social competence, problem behavior, and…
