Knowledge and awareness about osteoporosis and its related risk factors are important contributors to osteoporosis preventive behavior. There is a need to assess the reliability of international osteoporosis-related knowledge and belief measurement tools in Arabic community. This study aimed to assess the reliability of the Arabic version of Osteoporosis Knowledge Assessment Tool (OKAT) and the Osteoporosis Health Belief Scale (OHBS) among Syrian women.
The study included two phases. The first phase included a forward and backward translation of the osteoporosis-related tools (OKAT and OHBS) followed by a pilot testing. The second phase was an assessment of the test-retest reliability of the tools among a convenience sample of one hundred working women at Damascus Faculty of Medicine and its teaching hospitals. For this purpose each instrument was administered twice to all women at an interval of two weeks. Data collection took place in the fall of 2011, and was facilitated by a trained interviewer whose task was to administer the tools and collect some background data from the women who consented to participate in the study.
A total of one hundred women were recruited in this study for the reliability test-retest of the Arabic version of the tools. The mean age of studied women was 37.1 (SD = 8.4) years. Most of the women were married and nearly one-half of them had a university education. The internal consistency values for OHBS (Cronbach's alpha = 0.806) as well as the OKAT (Cronbach's alpha = 0.824) met the 0.7 Cronbach's alpha value requirement. Item analysis did not necessitate any omissions in either tool. McNemar's test identified only three items on the OKAT questionnaire that significantly differed from the test to the retest. The OKAT mean score (SD) for the test was 9.4 (2.6) and that for the re-test was 10.1 (2.9). Paired t test did not show significant difference (P = 0.068).
The Arabic version of both the Osteoporosis Knowledge Assessment Tool (OKAT) and the Osteoporosis Health Belief Scale (OHBS) was found to be reliable as well as acceptable. Further research is needed as to complete the validation of those tools and to use them at larger scale whether in knowledge assessment or in assessing interventions.
对骨质疏松症及其相关危险因素的了解和认识是预防骨质疏松症行为的重要因素。有必要评估国际骨质疏松症相关知识和信念测量工具在阿拉伯社区的可靠性。本研究旨在评估叙利亚女性中骨质疏松症知识评估工具（OKAT）阿拉伯语版和骨质疏松症健康信念量表（OHBS）的可靠性。
该研究包括两个阶段。第一阶段包括对骨质疏松症相关工具（OKAT和OHBS）进行正向和反向翻译，然后进行预测试。第二阶段是在大马士革医学院及其教学医院的100名职业女性便利样本中评估这些工具的重测信度。为此，每个工具对所有女性进行两次测试，间隔两周。数据收集于2011年秋季进行，由一名经过培训的访谈员协助进行，其任务是管理这些工具并从同意参与研究的女性中收集一些背景数据。
本研究共招募了100名女性对工具的阿拉伯语版进行重测信度测试。研究女性的平均年龄为37.1（标准差 = 8.4）岁。大多数女性已婚，其中近一半拥有大学学历。OHBS（克朗巴哈系数 = 0.806）以及OKAT（克朗巴哈系数 = 0.824）的内部一致性值符合克朗巴哈系数0.7的要求。项目分析表明两个工具都无需删减任何项目。麦克尼马尔检验仅在OKAT问卷上识别出三个项目在测试和重测之间存在显著差异。OKAT测试的平均得分（标准差）为9.4（2.6），重测的平均得分为10.1（2.9）。配对t检验未显示出显著差异（P = 0.068）。
骨质疏松症知识评估工具（OKAT）和骨质疏松症健康信念量表（OHBS）的阿拉伯语版被发现是可靠且可接受的。需要进一步研究以完成这些工具的验证，并在更大范围内使用它们进行知识评估或评估干预措施。
