本研究旨在以自我決定理論主張之行為調節探討大學生18個月階段改變屬性,並檢驗不同階段改變屬性在行為調節趨向情形。研究採縱貫調查進行,對象為458位完成四次評量大學生,平均年齡21.58(SD=5.21)歲,男、女生各有228、230人。評量工具包含運動階段改變問卷、運動行為調節問卷。將所得資料以兩階段集群分析、趨向分析處理。結果發現階段改變可因行為調節變項存在高、中、低自我決定組別,高比低組別在改變歷程有較高整合、認同調節,且有較多持續期人數比例;低比高組別在改變歷程有較高外在調節,並有較多無意圖期、意圖期人數比例。經討論獲得結論為:行為調節是改變大學生運動階段重要因素,自我決定愈高,愈有利於規律行為的養成與維持。
The purpose of this study was to adopt a behavior regulation of self-determination theory to investigate the attributes of stage of change among undergraduates. Furthermore, to test the relationships between trends in behavior regulation and the different attributes of stage of change during 18 month. The longitudinal approach survey was utilized in this study, and total 458 undergraduate students (male-228, female-230, aged 21.58±5.21) were participated and completed four questionnaires assessing stage of change for exercise and behavior regulation in the 18-month period. The measurement tools include the stage of change for exercise questionnaire and the behavior regulation in exercise questionnaire. All of the collected data has been analyzed by using two-approach cluster analysis and trend analysis. The results indicated that the behavior regulation could be the stage of change from the high, medium and low self-determined groups. The high self-determined had higher proportion of maintenance than low self-determined, and significantly higher integrated and identified regulation in the stage transitions. The low self-determined had higher proportion of precontemplation or contemplation than high self-determined, and significantly higher external regulation in the stage transitions. This study concluded that the behavior regulation was to change the stages of important factors, and the high self-determined was more conducive to the formation of regular exercise.
