The use of qualitative research in Public Service Motivation research is growing and its impact on the field is beginning to be felt. This study contributes to our understanding of PSM by exploring the dimension of “commitment to public interest” and the challenges to development in Ghana. The analysis of 34 semi-structured in-depth interviews conducted with employees of the Financial Intelligence Centre demonstrates that commitment to public interest is influenced by leadership actions and organizational culture. The outcome of this paper is useful for public organizations in their attempt to improve employee commitment and productivity in the public sector.
