The purpose of this study was to refine scales to measure Health Belief Model concepts of benefits and barriers using the context of mammography screening. Both scales used a summated Likert format with five response options. Items were first subjected to content analysis by national experts. Data were then collected from a random sample of 581 women who were 35 years or over. Retest data were gathered on a subset of women approximately 4-6 weeks later. Construct validity was established using confirmatory factor analysis and exploratory factor analysis with results confirming independence of constructs. Construct validity was also tested by developing hypotheses based on theoretical relationships. Cronbach alpha reliability coefficients for the benefits scale was 0.79 and for the barriers scale was 0.73. Suggestions for further revisions are offered.
本研究的目的是在乳腺钼靶筛查的背景下完善量表，以测量健康信念模型中的益处和障碍概念。两个量表均采用五分制李克特量表形式。项目首先由国家专家进行内容分析。然后从581名35岁及以上的女性随机样本中收集数据。大约4至6周后，对一部分女性收集了重测数据。通过验证性因素分析和探索性因素分析建立结构效度，结果证实了各结构的独立性。还通过基于理论关系提出假设来检验结构效度。益处量表的克朗巴哈α信度系数为0.79，障碍量表的为0.73。文中还提供了进一步修订的建议。
