The aims of this study were to translate and examine the psychometric properties of the Malaysian version of the Osteoporosis Health Belief Scale (OHBS-M) among type 2 diabetes patients (T2DM) and to assess the correlation between osteoporosis knowledge, health belief and self-efficacy scales, as well as assess the osteoporosis risk in the sample population using quantitative ultrasound measurement (QUS).
A standard 'forward-backward' procedure was used to translate OHBS into the Malay language, which was then validated with a convenience sample of 250 T2DM. Bone mineral density (BMD) measurements were carried out using QUS at the calcaneus.
The mean score of OHBS-M was 158.31 ± 20.80. The Fleiss' kappa, content validity ratio range and content validity index were 0.99, 0.75-1.00 and 0.88, respectively. Seven factors of the OHBS-M were identified using exploratory factor analysis and were confirmed through confirmatory factor analysis. Internal consistency and test-retest reliability values were 0.89 and 0.555, respectively. In addition, only 22% had a normal BMD (low risk of abnormal BMD), while osteopenia and osteoporosis were 57.6% and 20.4% (considered as high risk of abnormal BMD), respectively.
The results showed that the OHBS-M is a reliable and valid instrument for measuring health belief toward osteoporosis in diabetic patients. In addition, it is an appropriate tool to identify patients needing a bone health-promoting intervention regarding lifestyle behavior changes in a clinical setting. Moreover, the sample population showed high risk of osteoporosis and would subsequently benefit from dual-energy x-ray absorptiometry scanning for definite evaluation and treatment.
本研究旨在翻译并检验马来西亚版骨质疏松症健康信念量表（OHBS-M）在2型糖尿病患者（T2DM）中的心理测量特性，评估骨质疏松症知识、健康信念和自我效能量表之间的相关性，并使用定量超声测量（QUS）评估样本人群的骨质疏松症风险。
采用标准的“前后”程序将OHBS翻译成马来语，然后用250名T2DM的便利样本进行验证。使用QUS在跟骨处进行骨密度（BMD）测量。
OHBS-M的平均得分为158.31±20.80。Fleiss'kappa、内容效度比范围和内容效度指数分别为0.99、0.75 - 1.00和0.88。使用探索性因素分析确定了OHBS-M的七个因素，并通过验证性因素分析得到证实。内部一致性和重测信度值分别为0.89和0.555。此外，只有22%的人骨密度正常（骨密度异常风险低），而骨质减少和骨质疏松分别为57.6%和20.4%（被认为骨密度异常风险高）。
结果表明，OHBS-M是一种可靠且有效的工具，可用于测量糖尿病患者对骨质疏松症的健康信念。此外，它是一种合适的工具，可用于识别在临床环境中需要进行生活方式行为改变以促进骨骼健康干预的患者。此外，样本人群显示出较高的骨质疏松症风险，随后将受益于双能X线吸收测定扫描以进行明确的评估和治疗。
