The Effect of Diet Training on Quality of Life and Subjective Happiness in Celiac Patients: A Randomised Controlled Trial

Aims This study aimed to examine the effect of nurse-led diet training on quality of life and subjective happiness in adults with celiac disease in remission. Design: This study is a discussion article based on findings from an experimental intervention. Data Sources: Data were collected between 1 March and 1 August 2023 through face-to-face interviews using validated assessment tools. Implications for Nursing: The findings emphasize the essential role of nurses in celiac disease management through structured, evidence-based diet training. Nurse-led dietary education supports lifelong adherence to a gluten-free diet by enhancing patients’ knowledge, addressing psychosocial challenges, and promoting effective coping strategies. Integrating regular diet training into routine nursing care may improve patient outcomes, reduce disease-related complications, and support holistic, biopsychosocial care. Conclusion Nurse-led diet training resulted in meaningful improvements in both quality of life and subjective happiness among adults with celiac disease. Given the lifelong dietary restrictions and behavioral demands of celiac disease, strengthening patient education strategies and identifying factors influencing dietary adherence are critical to optimizing long-term clinical and psychosocial outcomes. Impact: This study demonstrates that nurse-led diet training yields clinically relevant benefits, supported by moderate to large effect sizes. The findings highlight dietary education as a practical and cost-effective nursing intervention that can enhance patient well-being, improve treatment adherence, and potentially reduce long-term healthcare utilization. Patient or Public Contribution: Patients with celiac disease participated by completing validated questionnaires and engaging in face-to-face interviews. Although patients were not involved in the design phase of the study, their responses and shared experiences contributed to determining patient-centered outcomes for nursing practice.
