Objective To explore the peer support experiences of patients with spinal cord injury during home rehabilitation, and to provide references for developing and improving peer support intervention strategies. Methods Based on the Theory of Social Support,a descriptive qualitative research method was used to conduct semi-structured interviews with 12 patients with spinal cord injury during home rehabilitation by purposive sampling. Content analysis was used to encode, classify, interpret and comprehensively analyze the data. Results Four main themes and eleven sub-themes were identified:ways to obtain peer support and forms of interaction(autonomous connection through informal channels, the introduction and organization of professional institutions, an interactive form of online and offline integration), core values of peer support (emotional support and psychological adjustment, experiential knowledge and practical guidance, self-growth and identity transformation, infusion of hope and confidence), perceived characteristics of peer support (deep empathy and psychological belonging, unique and irreplaceable), limitations and risks of peer support (emotional infection and psychological depletion, lack of information accuracy and professionalism). Conclusion Healthcare professionals should actively build a systematic and standardized peer support network system for patients with spinal cord injury, and deeply grasp the core value of peer support to fully activate its unique functions and advantages.At the same time, attention should be paid to identify the limitations and potential risks of peer support, and optimize intervention strategies to ensure the effectiveness and sustainability of peer support.
