This study examines how government anti-corruption policies have influenced police officers' perceptions of corruption in Ghana over a decade. The study employed a longitudinal design with data collected through surveys administered to police officers in Ghana at both time points. The CPI scores were analysed for trends over time. A significant decrease in CPI scores was observed among police officers from to , indicating improved perceptions of corruption control efforts by the government. The findings suggest that despite some challenges, anti-corruption policies have had a positive impact on reducing perceived levels of corruption within Ghana's police force. However, persistent issues remain. Further research is recommended to explore the effectiveness of specific anti-corruption measures and to identify areas for improvement in policy implementation.
