Women's beliefs regarding breast cancer and its screening approaches were considered antecedents of their behavioral changes. Understanding of these beliefs in women requires a valid and reliable instrument. The present study seeks to translate the English version of the Champion's Revised Health Belief Model Scale (CRHBMS) into the Persian language and assess its psychometric properties.
The study was conducted on 334 students at Urmia University of Medical Sciences, Iran, 2016. The 57-item CRHBMS was translated to Persian language, back translated, and tested. To test the face and content validity of the Persian version; item analysis, Content Validity Ratio (CVR), and Content Validity Index (CVI) were applied, respectively. Construct validity of the Persian scale was performed by Exploratory and Confirmatory Factor Analyses (EFA, CFA) using Kaiser-Meyer-Olkin and Bartlett's tests in SPSS 16 and LISREL8.72 software. The reliability of the translated scale was evaluated using Cronbach's alpha and test-retest approaches.
In the EFA, eight factors were extracted concerning breast cancer screening, and each item was loaded on its specific factor. These factors were self-efficacy, health motivation, benefits-mammography, benefits-Breast Self-Examination (BSE), barriers-mammography, barriers-BSE, susceptibility, and severity. The final 42-item scale was confirmed by the CFA, and all goodness of fit indices showed a proper fit of the model. Cronbach's alpha coefficient and test-retest correlation of the subscales ranged from 0.72-0.89 and 0.67-0.93, respectively.
The study suggests that the Persian version of CRHBMS is a feasible scale for evaluating women's health beliefs regarding breast cancer and its screening behaviors.
女性对乳腺癌及其筛查方法的信念被认为是其行为改变的先决条件。了解女性的这些信念需要一个有效且可靠的工具。本研究旨在将冠军修订版健康信念模型量表（CRHBMS）的英文版翻译成波斯语，并评估其心理测量特性。
该研究于2016年在伊朗乌尔米亚医科大学对334名学生进行。57项的CRHBMS被翻译成波斯语，进行回译并测试。为测试波斯语版本的表面效度和内容效度；分别应用了项目分析、内容效度比（CVR）和内容效度指数（CVI）。使用SPSS 16和LISREL8.72软件中的Kaiser-Meyer-Olkin和Bartlett检验，通过探索性和验证性因子分析（EFA、CFA）对波斯语量表进行结构效度分析。使用Cronbach's alpha和重测法评估翻译后量表的信度。
在探索性因子分析中，提取了八个与乳腺癌筛查相关的因子，每个项目都加载到其特定因子上。这些因子是自我效能感、健康动机、乳腺钼靶检查的益处、乳房自我检查（BSE）的益处、乳腺钼靶检查的障碍、BSE的障碍、易感性和严重性。最终的42项量表通过验证性因子分析得到确认，所有拟合优度指标均表明模型拟合良好。各子量表的Cronbach's alpha系数和重测相关性分别在0.72 - 0.89和0.67 - 0.93之间。
该研究表明，CRHBMS的波斯语版本是评估女性对乳腺癌及其筛查行为的健康信念的可行量表。
