Aims The aims of this study were to translate and examine the psychometric properties of the Malaysian version of the Osteoporosi s Health Belief Scale ( OHBS ‐M) among type 2 diabetes patients (T2 DM ) 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 ). Methods A standard ‘forward–backward’ procedure was used to translate OHBS into the Malay language, which was then validated with a convenience sample of 250 T2 DM . Bone mineral density ( BMD ) measurements were carried out using QUS at the calcaneus. Results 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. Conclusion 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.
