Abstract
The purpose of this study was to validate of the parent education participation measurement scale(PEPMS) for golf player using Rasch partial credit model. Establishing content and face validity, 30-item(24-item: autonomy encourage factor, 6-item: exercise information supply factor) and 5-point scale were generated. The scale was administered to 213 golf player. The Rasch measurement computer program, WINSTEPS 4.2.0 was used to analyze the data. Model fit was decided by Infit and Outfit index (≥.60 and ≤1.40). The results are as follow. First 4-point scale was more appropriated than the 5-point scale that was showed the step calibration index increased step by step in each item. Second, the two factors were satisfied by the global fit statistics index as RMSR (Root mean square residual). Third, 2-item in the autonomy encourage factor was selected as the DIF(differential item functioning) between gender, and nothing item in the exercise information supply factor as the DIF between gender. Fourth, one item in the autonomy encourage factor was over the standard item fit (infit=1.40, outfit=1.55). The results indicated that 21 items in the autonomy encourage factor and 6 items in exercise information supply factor were finally selected. This study verified and showed the PEPMS that constructed 27-item and 4-point scale for golf player. In addition, the newly constructed this scale for golf players should be validated to increase external validity.
