To translate and cross-culturally adapt the Northwick Park Neck Pain Questionnaire (NPQ) into Hausa and assess its psychometric properties. The NPQ was translated and cross-culturally adapted into Hausa using recommended guidelines. A consecutive sample of 92 Hausa-speaking patients with non-specific neck pain recruited from three tertiary hospitals in north-western Nigeria, completed the questionnaire to assess factorial validity (using confirmatory factor analysis), convergent validity (by correlating the Hausa-NPQ with the Numerical Pain Rating Scale [NPRS]), and internal consistency (using Cronbach's α). A subsample of 50 patients completed the questionnaire again 3 days after the first administration to assess relative reliability using intraclass correlation coefficients (ICC) and absolute reliability using standard error of measurement (SEM), smallest detectable change (SDC), and 95% limits of agreement (LOA). The factor analysis confirmed a single-factor structure with excellent internal consistency (α = 0.94). The questionnaire showed a strong positive correlation with the NPRS (rho = 0.68). The ICC was 0.86, with SEM and SDC of 6.32 and 17.5, respectively. The LOA was − 29.3 to + 37.1 with no evidence of proportional bias. The Hausa-NPQ is a valid and reliable measure of disability due to neck pain. This study describes the translation, cross-cultural adaptation, and psychometric assessment of the Hausa-NPQ in Hausa-speaking patients with non-specific neck pain. The questionnaire demonstrated adequate psychometric properties in terms of factorial and convergent validity, internal consistency, and test-retest reliability. The questionnaire will be useful in clinical and research settings to assess disability due to neck pain for screening purposes, evaluation of treatment effectiveness, as well as cross-cultural comparisons involving Hausa-speaking individuals with neck pain.
