Despite frequent reference to the Health Belief Model (HBM), few studies address the internal consistency (within questionnaires) or the stability across populations of scales used to measure HBM variables. As part of a 1983 Michigan statewide blood pressure survey, trained interviewers administered 32 health belief questionnaire items to 2,802 randomly selected adult Michigan residents. Exploratory common factor analysis was used to examine the structure of these questionnaire items. Six correlated factors, which corresponded closely with theoretical constructs, appeared. Guided by these results, we developed a confirmatory common factor model. The model's fit was examined in random population halves and in univariate sex, race, and age subgroups. Except perhaps in the oldest age group, the model's fit appeared constant. Reliabilities estimated for HBM factor scales formed with these questionnaire items appeared independent of age, race, or sex.
尽管人们经常提及健康信念模型（HBM），但很少有研究探讨用于测量HBM变量的量表在问卷内部的一致性或在不同人群中的稳定性。作为1983年密歇根州全州血压调查的一部分，训练有素的访员向2802名随机抽取的密歇根州成年居民发放了32项健康信念调查问卷。采用探索性公共因子分析来检验这些问卷项目的结构。出现了六个与理论结构密切相关的相关因子。在这些结果的指导下，我们开发了一个验证性公共因子模型。在随机划分的人群以及单变量的性别、种族和年龄亚组中检验了该模型的拟合度。除了最年长的年龄组外，该模型的拟合度似乎是恒定的。用这些问卷项目形成的HBM因子量表的信度估计似乎与年龄、种族或性别无关。
