We investigated the health belief model and the health locus of control constructs as predictors of group membership (compliers or dropouts) with cardiac rehabilitation and whether they added predictive utility to routinely assessed patient demographics and health behaviors. Questionnaires were completed on entry into the study by 120 patients with coronary artery disease, and by the end of the 6 month program there were 58 compliers and 62 dropouts. Discriminant function analyses were carried out to determine prediction of group membership. The health belief model predicted group membership 64.6% of the time, explaining 5.2% of the variance. Demographics, health behaviors, and health belief model factors accounted for 21.1% of the variance between compliers and total dropouts with group membership correctly predicted 74.4% of the time; avoidable and unavoidable dropout was correctly predicted 84.2% of the time with 56.9% of the variance explained. Health locus of control did not distinguish between compliers and dropouts. The addition of the health belief model provided additional information about compliance with cardiac rehabilitation beyond that explained by demographic and health behavior variables alone, particularly when predicting avoidable/unavoidable dropout.
我们研究了健康信念模型和健康控制点结构，将其作为心脏康复治疗中组成员身份（依从者或退出者）的预测指标，并探讨它们是否能为常规评估的患者人口统计学特征和健康行为增添预测效用。120名冠心病患者在进入研究时完成了问卷调查，在为期6个月的项目结束时，有58名依从者和62名退出者。进行判别函数分析以确定组成员身份的预测情况。健康信念模型在64.6%的时间里预测了组成员身份，解释了5.2%的方差。人口统计学特征、健康行为和健康信念模型因素解释了依从者和退出者之间21.1%的方差，组成员身份在74.4%的时间里被正确预测；可避免和不可避免的退出在84.2%的时间里被正确预测，解释了56.9%的方差。健康控制点无法区分依从者和退出者。健康信念模型的加入提供了关于心脏康复依从性的额外信息，超出了仅由人口统计学和健康行为变量所解释的范围，特别是在预测可避免/不可避免的退出时。
