Readiness, or stage of change, is a key component of adopting regular exercise. Prochaska's transtheoretical model served as the theoretical framework for the study. At least 15 self-report measures have been published, yet no studies have evaluated the extent to which exercise stage of change classification may vary according to measure used. There is a need for research comparing exercise stage of change measures with different formats. The purpose of this study was to (a) determine the percent of subjects who had 100% agreement in stage classification on three commonly used instruments (scale-true false, scale-ladder, scale-five answer choice) and a structured interview; (b) determine agreement in classification among instruments; (c) determine agreement in classification among instruments and interview; and (d) determine if exercise self-efficacy (a common exercise predictor variable) is a predictor of exercise stage of change classification across all measures. This cross-sectional study used a one-group design. Ninety-five healthy adults, aged 19 to 62, completed the four exercise stage of change measures in random order and then completed an exercise self-efficacy scale. The first stage of change, precontemplation, was not used in data analysis due to few subjects classified in this stage. There was 100% agreement in classification across instruments in 62% of the subjects; there was 100% agreement in classification across instruments and interview in 57% of the subjects. Among instruments, there was most agreement between scale-five answer choice and scale-ladder (kappa = 0.82, p < .01). Among instruments and interview, there was most agreement between scale-ladder and the structured interview (kappa = 0.86, p < .01). Exercise self-efficacy was a significant (p < .01) predictor of stage classification across all exercise stage of change measures Recommended revisions are to enhance clarity of wording on scale-true false scale-ladder and scale-five answer choice, and improve format of scale-ladder. The current study on agreement represents a first step in working toward standardization of exercise stage of change measures.
