Small and medium-sized enterprises (SMEs) act as drivers of economic growth due to their positive impact in creating jobs and driving social change. However, their owner-managers (entrepreneurs) generally face a lot of stress in running a business through role conflicts, working long hours, high time pressure, coping with past failures and managing many economic demands. This project examines the impact of a psychosocial intervention on the business performance of female entrepreneurs in Nigeria. This project update shares the methodology used to address this research question and early insights that have emerged so far.
