The effect of communication therapy based on the Peplau model on sense of coherence and psychological well-being in people with chronic renal failure undergoing hemodialysis: a quasi-experimental study

Background and Aim Hemodialysis is a stressful treatment for chronic kidney failure, often leading to psychological issues like anxiety and depression. Sense of coherence and psychological well-being are vital for coping with these stresses. This study aimed to evaluate the effect of therapeutic communication based on Peplau’s model on these parameters in hemodialysis patients. Methods This semi-experimental study involved patients with chronic kidney failure undergoing hemodialysis at Hajar Hospital in Shahrekord. Participants were randomly assigned to intervention (Peplau-based communication therapy) and control (routine care) groups. The intervention was delivered over 7–8 individual sessions. Data were collected using Antonovsky’s Sense of Coherence Scale and Ryff’s Psychological Well-Being Questionnaire, and analyzed with SPSS 28. Results There were no significant demographic differences between groups. In the intervention group, sense of coherence and psychological well-being scores significantly improved immediately and two months post-intervention ( P < 0.001). No significant changes were observed in the control group. Clinical trial number IRCT20251011067591N1. Conclusion Therapeutic communication based on Peplau’s model significantly enhanced psychological well-being and sense of coherence in hemodialysis patients. It is a practical and effective intervention to support mental health in this population.
