Patients were informed about the application, and a Reiki application video prepared/selected by the researchers was shared with the patients. Patients were asked to perform Reiki every day for a week following each chemotherapy session for 4 cycles. A reminder message was sent to the patients the day before each cycle for the Reiki application. The level of hopelessness was reassessed at the end of each week.

Only data collection forms were filled in the control group. No intervention was made.

Individual Information Form: The form prepared by the researchers consists of 14 questions.

Beck Hopelessness Scale: The Beck Hopelessness Scale was developed by Beck and colleagues in 1974 to determine the degree of pessimism an individual has about the future. The scale consists of 20 items in a five-point Likert format. The questions are answered as true or false and reflect negative expectations. Each answer that matches the given key scores 1 point, while answers that do not match score 0 points. The total score obtained is considered the "hopelessness" score, with higher scores indicating higher levels of hopelessness. The scale's score range is 0-20. The questions on the scale cover emotional, motivational, and cognitive dimensions. The scale consists of three factors: "Feelings about the Future," "Loss of Motivation," and "Future Expectations" (Durak & Palabıyıkoğlu, 1994). In this study, the Cronbach's Alpha value for hopelessness was calculated as 0.952.
