Validity and reliability of teachers’ perceived beliefs about the purposes of physical education questionnaire

Abstract

The purpose of this study was to examine the psychometric properties of the Teachers’ Perceived Beliefs about the Purposes of Physical Education Questionnaire. A total of 473 school physical education teachers in Singapore took part in the study. The sample was randomly split into two sets. An initial measurement model was assessed using a confirmatory factor analysis (CFA) based on the calibration sample (n = 235). Next, a modified measurement model was proposed based on the first CFA results and tested with the validation sample (n = 238). Finally, a two-stage factorial invariance analyses (Jöreskog & Sörbom, 1993) was employed to ensure concurrent validation for the modified model with both sample sets. The results showed that the cross validation of the modified measurement was not supported by the data of the two samples. Specifically, the factors of being a good citizen and self-esteem lacked convergent validity.
