Background/Aims: The aim of this study was to translate and cross-culturally adapt initiated psychometric tests of the Neck Disability Index (NDI) questionnaire into Hausa language. The prevalence of neck conditions among Hausa patients in Northern Nigeria necessitates the use of the NDI questionnaire. The fact that there was no Hausa version of this instrument has limited its use, hence there is a need for its translation into the Hausa language. Methods: The English version of the NDI questionnaire was translated into Hausa language through a forward and backward translation process. Sixty-two patients were selected for validation of the questionnaire using a purposive sampling technique. The original English version (NDI) and the Hausa version (NDI-H) were administered to the patients and re-administered within the space of one week to ensure validation. Psychometric testing was done to ascertain reliability and construct validity. Findings: The Hausa version of the NDI showed good internal consistency (α= 0.741) and test-retest reliability of r=0.84, p< 0.05. The responsiveness analysis revealed a significant relationship (r = 0.47, p=0.01). Factor analysis revealed a 2-factor 10 items structure which explained the variance of 49.7%. Conclusions: The NDI was successfully translated into Hausa language and validated with good psychometric properties.
