Effect of Nutrition Education on the Quality of Life, Chronic Disease Adaptation in Patients With Thyroid Dysfunction

This thesis study is designed to examine the effects of nutrition education provided to individuals with thyroid dysfunction on their quality of life and adaptation to the disease. The data will be collected using the Descriptive Characteristics Form, the Nutrition Attitude Scale, the Quality of Life Scale for Thyroid Patients (ThyPRO), and the Chronic Illness Adherence Scale. The Body Mass Index (BMI) of participating patients will be calculated by the researcher based on measured height and weight. Laboratory values including TSH, free T4, and free T3 will be obtained from the patients' medical records on the day of assessment. Data collection will be conducted in two phases. The study population will consist of all patients diagnosed with thyroid dysfunction who present to Dr. Burhan Nalbantoğlu Hospital. Using the G\*Power 3.1.9.2 software, the required sample size was calculated prior to data collection with a 95% confidence level. For correlation analysis, an alpha value of 0.05, an effect size of 0.455, and a statistical power of 95% were assumed, resulting in a minimum sample size of 56 participants (30 per group). Accounting for potential data loss, a total of 60 patients (30 per group) are planned to be included in the sample.
