Abstract: Background Evaluating physical activity (PA) patterns in Sub-Saharan Africa requires linguistically adapted and psychometrically robust self-report instruments. This study evaluated the cross-cultural adaptation, criterion-related validity, and psychometric agreement of the Hausa version of the International Physical Activity Questionnaire Short Form (IPAQ-SF) against objective triaxial accelerometry and cardiorespiratory fitness (VO 2max ) among university students in Nigeria. Methods A cross-sectional validation study was conducted among N = 106 university students (56 men, 50 women; age 23.80 ± 2.14 years). Participants completed the self-administered Hausa IPAQ-SF, wore an ActiGraph triaxial accelerometer for 7 consecutive days (≥ 10 h/day wear time over ≥ 4 days required), and underwent submaximal treadmill testing using the Modified Balke protocol to estimate VO 2max . Criterion validity was evaluated via non-parametric Spearman’s rank correlation coefficients (ρ). Absolute psychometric agreement and systematic bias were quantified using Bland-Altman analysis with 95% Limits of Agreement (LoA) and proportional bias regression models. Results The Hausa IPAQ-SF walking subscale demonstrated a statistically significant, moderate positive correlation with accelerometer-tracked walking volume (ρ = 0.38, p < 0.001). Vigorous physical activity (VPA) exhibited a weak positive correlation with accelerometer-derived VPA (ρ = 0.24, p = 0.013), but showed a significant inverse correlation with estimated VO 2max (r = -0.30, p = 0.002). No significant correlations were observed for moderate physical activity (MPA; ρ = 0.10, p = 0.308) or sedentary time (ρ = 0.11, p = 0.262). Bland-Altman analysis revealed a systematic positive proportional bias (y = 0.284x − 176.3, t = 4.12, p < 0.001), with the Hausa IPAQ-SF overestimating total PA by a mean of + 142.5 MET-min/week (95% LoA: -399.2 to + 684.2 MET-min/week). Overall, 94.3% of individual data points fell within the 95% agreement boundaries. Conclusion The Hausa IPAQ-SF exhibits acceptable criterion validity for capturing ambulatory walking behaviors and high-intensity movement patterns in Hausa-literate young adults. However, the instrument demonstrates proportional overestimation bias and fails to yield valid estimates for moderate physical activity or sedentary duration. Researchers should pair the Hausa IPAQ-SF with objective motion sensors when evaluating low-to-moderate physical activity and sedentary patterns in clinical or epidemiological surveillance.
