The Effect of a Mobile Application on Patient Outcomes in Colorectal Cancer Patients

Patients will use the mobile application for 6 weeks after receiving the first course of chemotherapy. The Multidimensional Scale of Perceived Social Support, Memorial Symptom Rating Scale, EORTC QLQ-C30 Quality of Life Scale and QLQ-CR29 Module, Beck Anxiety Scale will be administered when they come to the hospital for their 2nd course of chemotherapy. Patients will use the mobile application for 6 more weeks after receiving the second chemotherapy course. 3. The scales will be reapplied when they come to the hospital for a chemotherapy course. Patients will continue to use the mobile application for three more weeks after receiving their 4th and final cure. When the patients come to the outpatient clinic control in the 12th week, the use of the mobile application will be terminated and the Mobile Application Efficiency Evaluation Form will be applied together with the other scales.
