The study examines the effect of coaching on the well-being of refugees in Greece when their housing needs are met. Forty two refugees in Greece were provided with a year-long housing contract and 8 sessions of coaching. Participants were matched for demographic characteristics and then randomly assigned to the control or the experimental group. The experimental group received both provisions and the control group received only the housing provision. After data were collected, the control group also received coaching for ethical reasons. The treatment was the coaching and housing was a confounding variable. Data were collected and analysed with qualitative methods (in-depth interviews) and with quantitative methods (the WHO-5 well-being questionnaire) at three points: immediately after all participants received the housing provision(Phase 1), immediately after the experimental group finished with coaching (Phase 2), and 3 months after the experimental group finished with coaching (Phase 3). The findings show that coaching statistically improved the well-being of refugees and that this positive effect continued to increase after phase 2. The well-being of the control group remained the same throughout the study. The study concludes first that coaching may increase the well-being of refugees when their housing needs are met and second, that a "housing first" approach may be an enabler of the positive effect of coaching on the well-being of refugees.
