Analytical Investigation of Factors Influencing Radiographer Job Satisfaction Across Nigerian Geopolitical Zones: A Multi-Site Empirical Study

Radiographer job satisfaction is a critical determinant of workforce retention, service quality, and patient safety outcomes in Nigerian healthcare, yet the factors shaping satisfaction have not been empirically examined across multiple geopolitical zones simultaneously. This study analytically investigates the demographic, organisational, and professional factors predicting radiographer job satisfaction across all six Nigerian geopolitical zones. A cross-sectional analytical survey is conducted among 480 registered radiographers selected through proportionate stratified sampling from 36 hospitals, six per zone. The validated Minnesota Satisfaction Questionnaire Short Form measures intrinsic, extrinsic, and overall satisfaction, alongside measures of workload, remuneration, career development opportunity, equipment adequacy, and management support. Multiple linear regression and structural equation modelling in AMOS identify direct and indirect predictors of satisfaction. Available job satisfaction literature from Nigerian radiography identifies remuneration inadequacy and equipment inadequacy as the dominant dissatisfaction drivers, yet zonal comparisons of these relationships are absent. The Job Demands-Resources Model provides the theoretical framework for analysing the satisfaction pathway. Findings are expected to reveal significant zonal variation in satisfaction determinants, with equipment adequacy having a stronger effect in South East and North East zones and remuneration dominance in the North West and South West zones. The study fills a gap in multi-zonal evidence on radiographer satisfaction. Recommendations address a national radiographer retention strategy addressing geographically differentiated workforce challenges.
