摘要：Context: Understanding changes in athletic training program (ATP) commitment over time is crucial in retaining high-quality students in an ATP. Objective: The purpose of this study was to examine if changes over time in ATP commitment determinants are related to actual changes in ATP commitment. Design: Longitudinal and cross-sectional survey. Setting: Commission on Accreditation of Athletic Training Education-accredited ATP. Patients or Other Participants: A total of 99 male and female athletic training students participated in Time 1. A total of 71 (39% males, 61% females) of the original 99 participants participated in Time 2. Participants ranged in age from 18 to 24 years (mean = 20.05, standard deviation = 1.28). Data Collection and Analysis: Previously validated measures assessed students' perceptions of enjoyment, attractive alternatives, investments, social constraints and support, benefits and costs, and commitment to ATP over time. Change scores for Times 1 and 2 were calculated for each predictor and commitment to ATP. Two multiple regression analyses determined which changes in the determinants of commitment predicted a change in commitment. A repeated-measures analysis of variance (ANOVA) determined the magnitude of change in the model variables over time. Lastly, a multivariate ANOVA compared who continued, graduated, and discontinued in the ATP. Results: Increases in investments and enjoyment predicted positive changes in commitment from Time 1 to Time 2. Additionally, decreases in classmates' social constraints and increases in professors' social constraints positively predicted changes in commitment. When exploring the magnitude of change in the model variables, only increases and decreases in enjoyment from Time 1 to Time 2 were related to concomitant changes in commitment. Lastly, graduating students reported lower commitment and enjoyment and higher perceived costs than did those students who remained in the ATP and had not yet graduated. Conclusions: Athletic training program commitment predictors tend to change over time; ATP enjoyment is critical to continued motivation.
