Financial difficulties and mental health are closely interlinked, with each influencing the other. Managing finances poses a major challenge for individuals living with psychosis. To better understand these challenges, it is important to adopt a qualitative approach that captures perspectives from all members of the therapeutic triad. This study explores how people with psychosis, their family members, and mental health professionals perceive financial problems and the factors contributing to them. Using purposive sampling, we recruited 14 individuals with psychosis, 15 family members, and 16 professionals. Participants took part in semi-structured, individual interviews. Data were examined through an iterative thematic analysis. Analysis revealed five main themes related to financial problems: managing daily expenses, financial skills and performance, housing and living conditions, interpersonal conflicts and vulnerability to exploitation, and challenges tied to regulations and legislation. Additionally, five categories of associated factors emerged: psychotic symptoms, indirect consequences of psychosis, substance use and addiction, financial socialization and life events, and broader societal influences. Across the therapeutic triad, participants described overlapping and often interrelated financial difficulties, highlighting the risk of reinforcing cycles of hardship. Breaking these cycles requires increased awareness and joint action among all stakeholders involved in the care and support of people with psychosis.
