The purpose of this study was to develop and validate an instrument based on the Transtheoretical Model (TTM) for assessing physical educators’ intentions and teaching behavior to implement evidence-based practice for students with disabilities. Study participants were 148 physical education teachers who were recruited from both elementary and secondary schools in Northwest regions of the U.S. Item analysis was conducted to evaluate appropriate discriminate functions for items measuring three TTM constructs (self-efficacy [SE], decisional balance [DB], and processes of change [POC]). Internal structures of the TTM items were examined by confirmatory factor analyses. The responses from stage of change were compared to the three TTM constructs. Separate one-way analyses of variance and multiple analyses of variance on each construct by stage were conducted to assess differences among the stages of change. Item discrimination values for all items were good to very good, except for two negative DB items that were deleted. Internal consistencies of SE, DB, and POC were found to be good to excellent. Confirmatory factor analyses showed reasonable squared multiple correlation and factor loading estimates. Three structural models were partially supported by goodness of fit indices. Cross-validation with a large sample size will be desirable to refine this measurement system in the future studies. KCI Citation Count: 0
