Studies have shown that the qualitative process assessment of cancer couple-based psychosocial interventions is often ignored. This article aims to evaluate the implementation process of an integrated psychosocial program developed for colorectal cancer couples. Semi-structured qualitative interviews were conducted with eight colorectal cancer couple participants and two intervention facilitators. Normalization Process Theory was used to guide the data collection and analysis. Data analysis was conducted using a directed content analysis approach within a framework approach. Participants had a good understanding of the program significance. For most participants, the intervention duration was appropriate, and was well integrated into daily life. A lack of understanding of psychological nursing, and a lack of confidence in the use of online platforms and other personal factors, inhibited participants' experience of participating in the intervention. The facilitator's challenge in the implementation process was being flexible in dealing with situations occurring outside of the framework plan. Face-to-face and online psychological interventions require more flexibility, and participant cognition of psychosocial care was the key to the successful implementation of the intervention. Future research should consider raising participants' awareness of psychological care to better integrate this type of intervention into participants' daily lives and routine care.
