The purpose of this study was to develop a questionnaire to assess body posture habits in adolescents' daily activities. To develop and assess the instrument we used the Delphi method, and a test-retest reliability design. The questionnaire consisted of 31 questions with 4-level Likert scale. One hundred and sixty-eight students were studied, 72…

Constraints-led approach (CLA) is widely used in physical education (PE). This four-phased study aimed to develop a self-report measurement of students' perceived constraints support in PE. The relationships among students' perceived constraints support, competence and novelty need satisfaction, motivation, effort, and engagement in PE were also…

Derived from the Expectancy-Value Theory (EVT) model, cost has drawn scholarly interest for being predicative of avoidance motivation. The study is an effort to develop and validate an instrument to measure students' perceived costs in physical education. Through literature review and student interviews, a draft of 39 items under seven domains was…

In combat sports, competition preparation is crucial, but research on this topic has been limited due to a lack of measurement tools. This study aimed to develop and validate the Multidimensional Assessment of Preparation for Sport Competition (MAPSC). In the first step, 61 athletes and 39 coaches collaborated to conceptualize and develop…

Using a multiphase approach, the purpose of the present study was to develop a psychometrically sound questionnaire to measure protégés' perceptions of peer athlete mentoring functions. Phase 1 consisted of three stages: (a) item development, (b) assessment of content validity via think-aloud interviews with peer mentored athletes, and (c)…

The purpose of this study was to develop an abbreviated version of the Perceived Motivational Climate in Exercise Questionnaire (PMCEQ-A) to provide a more practical instrument for use in applied exercise settings. In the calibration step, two shortened versions' measurement and latent model values were compared to each other and the original…

This study examined the psychometric properties of a questionnaire developed with the guidance of the socialization model of child behaviour to understand modifiable correlates of toddlers' physical activity and sedentary behaviour. Findings are based on 118 parents (33.7 ± 4.9 years; 86% female) of toddlers (19.3 ± 2.7 months; 48% female) from…

Organizational stressors can potentially elicit a number of undesirable consequences for sport performers. It is, therefore, imperative that psychologists better understand the demands that athletes encounter via their exploration and assessment. However, although researchers have identified a wide range of organizational stressors in competitive…

The current study presents the development process and initial validation of a measure designed for assessing psychological needs satisfaction in a secondary school physical education context (Psychological Needs Satisfaction Scale in Physical Education, PNSSPE). Junior secondary school (grades 7 to 9) students (N?=?1,258) were invited to…

The aim of the present study was to examine the validity and reliability of a multi-dimensional measure of trait anxiety specifically designed for the physical education lesson. The Physical Education Trait Anxiety Scale was initially completed by 774 high school students during regular school classes. A confirmatory factor analysis supported the…

New testing theories, concepts, and psychometric methods (e.g., item response theory, test equating, and item bank) developed during the past several decades have many advantages over previous theories and methods. In spite of their introduction to the field, they have not been fully accepted by physical educators. Further, the manner in which…

In addition to validity and reliability evidence, other psychometric qualities of the PE Metrics assessments needed to be examined. This article describes how those critical psychometric issues were addressed during the PE Metrics assessment bank construction. Specifically, issues included (a) number of items or assessments needed, (b) training…

The purpose of this study was to collect preliminary validity evidence for a time management scale for exercise. An initial pool of 91 items was developed from existing literature. Ten exercise/health psychologists evaluated each of the items in terms of relevance and representativeness. Forty-nine items met all criteria. Exploratory factor…

The purpose of this study was to develop the Scale for Program Facilitators (SPF) to assess the effectiveness of after school achievement programs through four steps: (a) identification of a theoretical framework, (b) formulation of the initial scale, (c) test of content validity, and (d) conducting confirmatory factor analyses (CFA). A…

This study extends validity evidence for the Coaching Efficacy Scale (CES; Feltz, Chase, Moritz, & Sullivan, 1999) by providing an evaluation of the psychometric properties of the instrument from previously collected data on high school and college coaches from United States. Data were fitted to a multidimensional item response theory model.…
