Based on the job demands--resources model, the study developed and validated an instrument that measures physical education teachers' job demands--resources perception. Expert review established content validity with the average item rating of 3.6/5.0. Construct validity and reliability were determined with a teacher sample (n = 397). Exploratory factor analysis established a five-dimension construct structure matching the theoretical construct deliberated in the literature. The composite reliability scores for the five dimensions range from .68 to .83. Validity coefficients (intraclass correlational coefficients) are .69 for job resources items and .82 for job demands items. Inter-scale correlational coefficients range from -.32 to .47. Confirmatory factor analysis confirmed the construct validity with high dimensional factor loadings (ranging from .47 to .84 for job resources scale and from .50 to .85 for job demands scale) and adequate model fit indexes (root mean square error of approximation = .06). The instrument provides a tool to measure physical education teachers' perception of their working environment. [ABSTRACT FROM AUTHOR]

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 elementary and 903 (6th–8th grades) from 13 middle schools. Students completed the EVQ in their physical education classes within the same semester. A series of hierarchical steps for testing the measurement invariance were conducted based on means and covariance structures. The results suggest that the questionnaire possesses configural and metric invariance, but noninvariant item intercepts between these two groups of students (∆CFI > .05). EVQ can be used to measure expectancy-value constructs in physical education for both middle-school and elementary students. Yet the noninvariant item intercepts posted questions on how the measured construct difference should be interpreted. [ABSTRACT FROM AUTHOR]
