BACKGROUND
The reliability and validity of the Champion's Health Belief Model Scale (CHBMS) used in assessing the belief of women regarding breast cancer (BC) and breast cancer screening (BCS) have been examined on various populations. However, the use of this tool has not been adequately assessed for its validity in ethnic minorities. This study assessed the validity and reliability of CHBMS by analyzing the factor structure and internal reliability of the factors among Yemeni women in Malaysia.
METHODS
A survey was conducted among 103 female teachers from 10 schools. SPSS version 22.0 was utilized in analyzing the data. Descriptive statistics were computed for the socio-demographic characteristics. The Cronbach's alpha coefficients were used in assessing the internal reliability. The Exploratory Factor Analysis (EFA) was used to analyze the factor structure of the translated items. Parallel analysis was performed to determine the number of factors accurately.
RESULTS
The alpha coefficients of the factors had acceptable values ranging between 0.76 and 0.87. The factor analysis yielded six and five factors for breast self-examination (BSE) and mammography (MMG), with a total explained variance of 47.69% and 52.63%, respectively. The Kaiser-Meyer-Olkin (KMO) index values of 0.64 and 0.72, and the Bartlett's Test of Sphericity (P = 0.0001) for BSE and MMG, respectively, verified the normality distribution and the adequacy of the sample size for EFA. All the items on each factor were from the same construct that were consistent with the number of factors obtained in the scale development study. The items achieved adequate factor loadings that ranged between 0.47 and 0.88.
CONCLUSIONS
The translated version of the CHBMS is a validated scale used in assessing the beliefs related to BC and BCS among Yemeni women living in Malaysia. Healthcare workers could use the scales to assess women's beliefs on BC and BCS. This instrument could be used to test the effectiveness of the intervention programs.
背景
冠军健康信念模型量表（CHBMS）用于评估女性对乳腺癌（BC）和乳腺癌筛查（BCS）的信念，其在不同人群中的可靠性和有效性已得到检验。然而，该工具在少数民族中的有效性尚未得到充分评估。本研究通过分析马来西亚也门女性的因素结构和内部信度，评估了 CHBMS 的有效性和可靠性。
方法
对 10 所学校的 103 名女教师进行了调查。使用 SPSS 版本 22.0 分析数据。对社会人口统计学特征进行描述性统计。Cronbach's alpha 系数用于评估内部信度。采用探索性因素分析（EFA）分析翻译项目的因素结构。并行分析用于准确确定因素的数量。
结果
各因素的 alpha 系数均具有可接受的值，范围在 0.76 至 0.87 之间。因素分析得出，乳房自我检查（BSE）和乳房 X 线照相术（MMG）的因素分别为 6 个和 5 个，总解释方差分别为 47.69%和 52.63%。BSE 和 MMG 的 Kaiser-Meyer-Olkin（KMO）指数值分别为 0.64 和 0.72，Bartlett 球形检验（P=0.0001），表明正态分布和 EFA 的样本量充足。每个因素的所有项目均来自同一结构，与量表开发研究中获得的因素数量一致。项目获得了 0.47 至 0.88 的充分因素负荷。
结论
该翻译版本的 CHBMS 是一种经过验证的量表，用于评估生活在马来西亚的也门女性与 BC 和 BCS 相关的信念。医疗保健工作者可以使用该量表评估女性对 BC 和 BCS 的信念。该工具可用于测试干预计划的效果。
