Translation and validation of the roland–morris disability questionnaire in hausa-speaking patients with low back pain

Introduction: Measuring outcomes in the health-care system has been very well understood among health-care specialists for the past few decades and has been widely acknowledged by various authors. Roland–Morris Disability Questionnaire (RMDQ) is one of the most commonly used measures of disability in patients with low back pain (LBP) and has been translated and validated into many different languages around the world. However, Hausa version of the questionnaire is yet to be established. This study developed and assessed the validity of RMDQ in Hausa-speaking patients with LBP. Materials and Methods: Eligible participants (n = 375; age = 37.5; standard deviation = 7.48) with either acute or chronic LBP completed both the original version of the RMDQ (RMDQ-O) and the Hausa version of the RMDQ (RMDQ-H). In addition, other outcome measures including the Oswestry Disability Index and the Berg Balance Scale were also completed by the participants to enable equivalence of data. Pearson's product-moment correlation was used to establish the validity of the RMDQ-H. Results: The result of this study revealed that the concurrent validity of the RMDQ-H produced a significant value of 0.786 (n = 375; P= 0.001). The convergent validity and the divergent validity of the RMDQ-H were 0.692 (n = 375; P= 0.001) and 0.013 (n = 375; P= 0.671), respectively. Conclusion: The developed RMDQ-H is a valid outcome measure of disability among Hausa-speaking patients with LBP.
