Psychosis is a severe mental disorder that substantially disrupts daily functioning. When experienced by individuals who are also fathers, the condition raises important questions about how symptoms influence paternal identity and parenting practices. This study explored how fathers who have experienced psychosis understand and navigate their role as parents. Semi-structured interviews were conducted with four fathers who had experienced at least one psychotic episode and who had at least one child. Interpretative phenomenological analysis was used to examine their accounts. The findings show that psychosis can profoundly alter fathers’ relationships with their children, particularly during acute episodes when hallucinations, delusions, and emotional withdrawal disrupt ordinary family life. Participants described uncertainty about their capacity to meet parental responsibilities, accompanied by persistent fears about their children’s future. Despite these challenges, the fathers reported that their children played a supportive and stabilising role, helping them to maintain their sense of being a parent. The fathers also highlighted that their children’s acceptance and involvement fostered emotional connection and contributed to their recovery. These findings suggest that fatherhood in the context of psychosis is characterised by both significant disruption and meaningful therapeutic potential within the parent-child relationship.
