This study aims to investigate the relevance of the theory of planned behaviour (TPB) in predicting the intentional behaviour of refugee entrepreneurs. This paper uses key components of the theory on attitude, subjective norms and perceived control to explore the willingness of refugees to participate in microenterprise support programmes (MESP) in refugee camps. This study used a positivist research approach, comprising a quantitative basis of enquiry and gathered data via survey questionnaires. In total, 400 usable questionnaires were completed and used for analysis. This study uses descriptive and inferential analysis with SPSS and confirmatory factor analysis with AMOS to test three key TPB hypotheses. The structured model revealed acceptable high goodness-of-fit indices. Also, the findings indicated that out of three hypotheses, two hypotheses (attitude and perceived control) were substantial, positive and significant. However, the relationship between subjective norms of refugees and their intention to participate in MESP was insignificant. The findings of this study indicate the low-profile refugees give to the views and opinions of the surrounding communities when it comes to determining their intentional behaviour. As such, some poignant implications may relate to microfinance and microcredit programmes targeting refugees. The present study illustrates the interrelationships between the proposed variables. Also, by understanding the relationships between the selected variables, the findings would be useful for the concerned authorities to ameliorate and upgrade the well-being of refugees along with empowering their environment, which would facilitate their engagement in business and entrepreneurship.
