Patients in the experimental group will be administered a "Patient Information Form" on the morning of surgery. Standard discharge education will be provided within 72 hours after surgery. After discharge, patients will be contacted at 1, 2, 3 weeks, and 2, 4, and 5 months for informational purposes only; no scales will be administered. During this period, regular follow-up and support will be provided to enhance patient compliance with post-surgical care. The "Interview Information Collection Form" will be used during telephone interviews with patients to collect and evaluate current health data. This practice will ensure the systematic and accurate recording of patients' current conditions. Patients will be contacted at 1, 3, and 6 months to complete the "Medication Adherence Scale" and the "Nutrition and Exercise Attitude Scale," which will collect data on medication adherence and behavioral attitudes.

Patients in the control group will be administered a "Patient Information Form" on the morning of surgery. This form will be used to assess the patients' demographic and clinical characteristics. Patients will receive standard discharge education within 72 hours after surgery and then be discharged. Post-discharge follow-up will be conducted via telephone at 1, 3, and 6 months. An "Interview Information Collection Form" will be used during telephone interviews to collect and evaluate current health data. This practice will ensure systematic and accurate recording of patients' current conditions. At each follow-up interview, patients will be administered the "Medication Adherence Scale" and the "Nutrition and Exercise Attitude Scale" to collect data on medication adherence and nutritional and exercise habits. These measurement tools will be used systematically to assess patients' treatment adherence and behavioral attitudes.

The Medication Adherence Reporting Scale (IAS) is a scale developed to assess medication adherence. The scale asks participants to evaluate five statements based on their own circumstances. This structure allows for the systematic examination of individual attitudes and behaviors toward medication use. The Medication Adherence Reporting Scale (IAS) is assessed using a 5-point Likert-type rating system, with response options of 5=never, 4=rarely, 3=sometimes, 2=often, and 1=very often. The test score is calculated by summing the scores obtained from the scale items.

The Nutrition and Exercise Attitude Scale (NUAS) was developed in Turkey to measure individuals' attitudes toward nutrition and exercise. Its validity and reliability study was conducted by Yurt (2008). It is structured as a Likert-type scale. This allows individuals to evaluate their own attitudes and behaviors based on various statements. The statements in the scale are rated on a scale according to individuals' level of agreement. Each item in the scale is scored, and a total score is calculated for the subdimensions. Higher scores indicate a more positive attitude in the relevant subdimension. Lower scores indicate that the individual is experiencing difficulties in a particular area. The internal consistency of the scale was assessed using Cronbach's Alpha coefficient and was found to be 0.70. This value indicates that the scale has an acceptable level of internal consistency (Yurt, 2008; Ekici and Yıldız 2018).
