PurposeCo‐creation, characterised by artists and patients creating a joint work of art, may support patients with the integration of life events, such as living with cancer, into their life story. In the process of co‐creation, resonance relationships between patients, artists and material may evolve that support such integration. Using the framework of resonance theory, we aim to investigate if and how patients move through the three phases of resonance during a process of co‐creation and explore the role of uncontrollability in this process.MethodsTen patients who received cancer treatment with palliative intent completed co‐creation processes, which were audio recorded. These recordings were imported in Atlas‐Ti and analysed by applying content analysis. We searched for the three phases of resonance, Being affected, touched and moved; Self‐efficacy and responding; Adaptive transformation. We additionally searched for signs of uncontrollability.ResultsPatients used 4–8 sessions (median 5 sessions) with a duration 90–240 min per session (median duration 120 min). We found that patients move through the three phases of resonance during co‐creation processes. Uncontrollability both presents a challenge and an invitation to integrate experiences of contingency into one's life narrative. Patients express self‐recognition and the experience of contingency in their work of art.ConclusionsIntegration of experiences of contingency into a life narrative can be supported by the process of co‐creation of art, which invites patients to relate to their illness, their environment and themselves. The phases of resonance in combination with uncontrollability as a continuously present factor, provide a means to both study and support the integration of experiences of contingency into the life narrative.
