Art therapy programmes have emerged as a promising intervention for addressing psychological distress among refugee populations. In the context of Congolese refugees in Kinshasa, DR Congo, there is limited empirical research exploring their effectiveness over time. A mixed-methods approach was employed, including pre- and post-programme surveys for quantitative data collection and qualitative interviews for deeper insights into participant experiences. Data were analysed using statistical software and thematic analysis. Participants reported a significant decrease in stress levels from baseline to follow-up (p < 0.05), with an average reduction of 23% in perceived stress scores. Themes emerged around the therapeutic benefits, including improved self-expression and coping strategies. Art therapy programmes appear effective in enhancing psychological wellbeing among Congolese refugees in Kinshasa. Further research should explore long-term effects and replication across different contexts. Given the positive findings, it is recommended that art therapy be integrated into mental health services for refugee populations as a cost-effective and accessible intervention.
