This randomized controlled trial aims to evaluate the effect of a navigator nurse-supported mobile application, developed based on the Information-Motivation-Behavioral Skills (IMB) model, on the quality of life of adult patients newly diagnosed with celiac disease. Participants will be randomized into intervention and control groups.
