In physical education and exercise science, it is common to examine mean differences between groups or to assess change across time. However, before group differences or change can be confidently examined, measurement invariance can be tested. Measurement invariance tests the equivalence of a construct across groups or across time. If measurement…

The purpose of this study was to develop the Youth Physical Activity Attitude Scale (YPAAS). Questions were developed using dual-component (affective-cognitive, positive-negative) beliefs framework. Content validity was established with expert panel review. Two samples of 4th-8th grade students (51% Female; 9-14 years) completed the YPAAS (sample…

Purpose: The objectives were to develop and validate the Coaches' Interpersonal Style Questionnaire. The Coaches' Interpersonal Style Questionnaire analyzes the interpersonal style adopted by coaches when implementing their strategy of supporting or thwarting athletes' basic psychological needs. Method: In Study 1, an exploratory factor analysis…

There are existing measures of exercise motives (what people want from exercise), but corresponding measures of gains (what people get) are needed, because motives and gains could influence each other and together influence other variables. An exercise motives and gains inventory (EMGI) was developed by creating gains scales to complement existing…

The purpose of this research was to develop a measure of sport injury anxiety (SIA), defined as the tendency to make threat appraisals in sport situations where injury is seen as possible and/or likely. The Sport Injury Anxiety Scale (SIAS) was developed in three stages. In Stage 1, expert raters evaluated items to determine their adequacy. In…

Expectancy-Value Questionnaire (EVQ) measures student expectancy beliefs and task values of the domain content (Eccles & Wigfield, 1995). In this study the authors examine measurement invariance of EVQ in the domain of physical education between elementary and middle-school students. Participants included 811 students (3rd-5th grades) from 13…
