Measurement Properties of Constraints to Sport Participation: A Psychometric Examination with Adolescents

摘要

Constraint are a major focus of theoretical and empirical study in leisure research. However, analyses of psychometric properties of constraints measures are rare. This study assessed the factor structure and invariance of a leisure constraints measure applied to sport participation among middle school adolescents (ages 11 to 15 years old) using panel data over two time periods nine months apart (N = 2,029). We compared the validity of three baseline models: a theoretical 3-factor model, a 7-factor model, and a second-order factor model. The 7-factor model exhibited a more appropriate measurement model based on fit indices and statistical comparisons. Using the 7-factor model, construct validity and invariance of the model over time (Time 1 and Time 2) was examined by gender, grade level, race/ethnicity, and socioeconomic status. The model was found to be invariant at the factor loading and intercept levels, while there was some evidence of non-invariance at further constrained levels. In general, the 7-factor model appeared to be psychometrically stable and applicable over a range of demographic subgroups, lending evidence to its use as a measure in leisure or sport participation constraint studies that involve socio-demographic comparisons. The findings suggest that while the theoretical structure may be effective in simplifying constraint categories, a more detailed specification using subfactors of the dimensions is better for measurement.View full textDownload full textKeywordsadolescents, barriers, constraints, invariance, measurement, middle school, sportRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/01490400.2011.550221
