title: Refinement and validation of the episode-specific interpretations of exercise inventory.
abstract: The purpose of this study was to refine an instrument to measure interpretations of exercise, the Episode-Specific Interpretations of Exercise Inventory (ESIE), and further examine its validity. This study was a secondary data analysis using community-dwelling older adults from two larger clinical trials. Fit indices from confirmatory factory analyses were strong. Cronbach's alphas for internal consistency reliability ranged from .70 to .91. Construct validity of the ESIE was supported by participants' reports of more sweating during the strength phase of exercise than during the flexibility phase and during the aerobic phase of exercise than during the flexibility and strength phases. In addition, correlations between the ESIE subscales and other feeling-related subscales made sense conceptually. In conclusion, that the ESIE provides a measure that examines older adults' exercise experience as well as their interpretations of that experience.
