The authors applied the stage-of-change construct in the transtheoretical model to examine the distribution of Asian (n = 869), African American (n = 373), White (n = 1322), and Hispanic (n = 535) American undergraduate students across the 5 stages of change for exercise. Stage of change varied as a function of ethnicity. Higher percentages of minorities were in the precontemplation and contemplation stages. The likelihood of being in these stages was from 43% to 82% greater for minorities than for White students. Also examined were the congruency between stage of change and self-reported levels of physical activity. Half of the sedentary students and 15.6% of the active students were misclassified by the stage-of-change procedure. Misclassification rates were higher for minority women (27.8%) than for White women (17.8%) and for Asian students (24.6%) compared with all others (20.6%). The results of this study have implications for the design of physical activity interventions based on stage of change.
作者运用跨理论模型中的行为改变阶段结构，研究了亚裔（n = 869）、非裔美国学生（n = 373）、白人（n = 1322）和西班牙裔美国本科生（n = 535）在运动行为改变的五个阶段中的分布情况。行为改变阶段因种族而异。少数族裔学生处于前意向和意向阶段的比例更高。少数族裔学生处于这些阶段的可能性比白人学生高43%至82%。研究还考察了行为改变阶段与自我报告的身体活动水平之间的一致性。在久坐不动的学生中，有一半以及在积极运动的学生中，有15.6%被行为改变阶段程序误分类。少数族裔女性的误分类率（27.8%）高于白人女性（17.8%），亚裔学生的误分类率（24.6%）高于其他所有学生（20.6%）。本研究结果对基于行为改变阶段设计身体活动干预措施具有启示意义。
