Development of a New Individual Interest Questionnaire in Physical Education

Recognizing the close interconnection between implicit-affective control and cognitive-rational aspects of individual interest, we designed this study to develop a new instrument - the Individual Interest Questionnaire in Physical Education (IIQ-PE). In study 1 (N=132), an exploratory factor analysis supported a model consisting of a single unified factor. In study 2 (N=117), Confirmatory Factor Analyses corroborated the construct validity of the IIQ-PE. Also, when examining multi-group invariance across the two study samples, no significant differences were found, suggesting that this factor structure held consistently. In study 3 (N=121), a path model further demonstrated that the individual interest significantly predicted learning strategies, the levels of attention, and self-confidence. The strong psychometric properties and the instrument's brevity together make the IIQ-PE a robust tool for evaluating students' individual interest in physical education.
