Young adults face unemployment-related challenges, particularly in low- and middle-income countries. Self-employment is encouraged by the Tanzanian government and international institutions such as the World Bank. It has been found that young adults who are employed or self-employed show more functional independence and less inequality and social polarization, as well as a decrease in deviant behaviour. However, limited knowledge and skills related to entrepreneurial activities contribute to lack of motivation towards self-employment among young adults. In order to examine these behaviours, an intervention study implementing an entrepreneurship and beekeeping training in Dar es Salaam, Tanzania was conducted. After completion of the intervention, a qualitative study was conducted that used focus group discussions (FGDs) to explore the experiences and changes in behaviour of young adults following the intervention. A total of 36 of the original 57 young adults from four camps who fully participated in the four arms of interventions were recruited. Qualitative content analysis was used to analyze the FGD data. Three themes emerged from the findings: establishment and maintenance of an entrepreneurial business, changes in behaviour, and perceived challenges. Improved entrepreneurial skills, customer care, and financial management were expressed as positive changes the participants attained relating to business management. Similarly, changes in the participants’ behaviours, attitudes, and lifestyle practices led to improved health and increased recognition and respect in their communities. Insufficient start-up capital and long intervals between sessions were the main challenges. The study showed an improvement in the ability of the participants to generate the human, social, and financial capital prerequisite to business development. Increase in customer care, social capital and financial management are key factors for successful microbusiness activities for stable self-employment.
