Developing personas for nutritional self-management in nasopharyngeal carcinoma patients: a qualitative study based on the Fogg Behavior Model

Rákkutatás · Nasopharyngeal carcinoma

Patients with nasopharyngeal carcinoma exhibit heterogeneous nutritional self‑management behaviors that can be categorized into five distinct personas based on motivation, ability, prompt, psychological state, and family support, enabling personalized nutritional interventions.

Malnutrition is common among nasopharyngeal carcinoma (NPC) patients and requires long‑term self‑management. Standard nutritional models are insufficient to meet diverse patient needs. This qualitative study, conducted from July–September 2025 in a Chongqing cancer hospital, recruited 21 NPC patients by purposive sampling and collected data through semi‑structured interviews. Directed content analysis, guided by the Fogg Behavior Model, generated a label framework covering motivation, ability, prompt, psychological state, and family support. Five behavioral personas emerged: proactive managers, symptom‑driven active managers, survival‑driven passive copers, cognition‑behavior disconnected individuals, and family‑led passive compliers. Nutritional self‑management behaviors varied markedly among NPC patients, allowing for personalized intervention strategies. Future work could develop a dynamic, persona‑based nutritional management system for NPC patients.

Malnutrition during NPC treatment worsens immune function, reduces radiotherapy efficacy, and lowers survival and quality of life. Identifying discrete behavioral patterns permits tailored nutritional support, potentially improving treatment adherence, clinical outcomes, and patient quality of life.
