Abstract

Belief about Medications Questionnaire (BMQ) is a validated tool to assess the beliefs of patients about their medications. The objective was to translate the BMQ in Hindi, and to perform reliability and validity testing of Hindi version in Indian children (aged ≤ 12 y) with difficult-to-treat nephrotic syndrome (DTNS). The BMQ was first translated using the standard translation and back-translation procedure. The BMQ-Hindi was then applied to 110 children with DTNS. The Principal component analysis was performed, and Cronbach alpha (CA) was calculated. Construct validity was tested by assessing the correlation (Pearson r) between BMQ-Hindi scores and Reported Adherence to Medication (RAM-Hindi) scale. The BMQHindi displayed two-factorial (five-item each) structure similar to BMQ-English. The CA was 0.79 and 0.63 for 'necessity' and 'concerns' subscale, respectively and was comparable to BMQ-English. BMQ-Hindi is a valid and reliable tool for Indian children with DTNS to assess parental beliefs about their child's medications.
