Hindi Translation, Cross-Cultural Adaptation, Validation and Reliability of Istanbul Low Back Pain Disability Index in patients with Chronic Mechanical Low Back Pain

The original Istanbul Low Back Pain Disability Index scale (ILBPDI), developed in a Western context, may not fully capture culturally specific stressors, social influences, or triggers experienced by low back pain population in India. In India, a vast population speaks Hindi, in addition to this, it is very challenging for them to understand English or any other language. Even if the therapist explains the items and contents in native Hindi language there is a great probability that the subject can misinterpret as the verbal meaning of words may not express the appropriate meaning as in the original questionnaire. This study will be of great importance and will aid the general population who cannot read and speak English. Translation of the ILBPDI scale for low back pain patients will add more meaning to the literature for the future. Therefore it enables the more accurate assessment of ILBPDI scale in chronic mechanical low back pain patients among Hindi-speaking populations, which will ultimately be contributing to more effective assessment strategies and improved public health outcomes in India. This study aims to translate each domain of the Istanbul Low Back Pain Disability Index scale (ILBPDI) into Hindi, to assess its validation, and evaluate test-retest reliability among Hindi-speaking populations. The aim is also to create an official Hindi version of the questionnaire. The study method involves translating the Istanbul Low Back Pain Disability Index scale (ILBPDI) from English into Hindi by two translators, T1 and T2, with medical and non-medical backgrounds, respectively. The recording observer then takes a seat to create a T12 version of the translated questionnaire. The reverse translation from the T12 form to the previous form is now being done. Then, an expert panel analyses all the stages and all of the questionnaire items to ensure that the translated form of the questionnaire is free of errors, allowing it to be field tested. Evaluation of the content’s validity is done. The pre-final form is then fully tested on patients, and the scale’s validity is reported. Finally, the translated questionnaire version will be analyzed by the ethics committee.
