The Effect of Reiki on Subjective Well-being, Happiness, and Some Metabolic Variables in Patients With Type-II Diabetes: Single-blind Randomized Controlled Trial

This study, designed as a randomized controlled trial with a pretest-posttest design, was conducted between September 2022 and August 2023 at the Internal Medicine clinic of Kanuni Sultan Süleyman Training and Research Hospital, Istanbul Provincial Health Directorate. The participants were voluntary individuals who had been diagnosed with Type-II Diabetes Mellitus at least 6 months prior, had a BMI ≥ 25kg/m² (overweight or obese), HbA1c ≥ 6.5%, were following a diabetes-specific diet or using oral antidiabetics, and were neither Reiki practitioners nor instructors. Randomization was used to assign participants to either the Reiki group or the control group. During the pretest, participants were asked to complete the Personal Information Form, the Subjective Well-Being Scale (SWS), and the OXFORD Happiness Scale (OHS). Pre-intervention fasting and postprandial blood glucose levels, HbA1c percentage, body mass index, LDL-HDL/total cholesterol, triglyceride levels, and blood pressure measurements were obtained from the patients' records and documented.The Reiki group received 20 minutes of remote Reiki once a day for 4 consecutive days, while no intervention was applied to the control group. The Subjective Well-Being Scale and OXFORD Happiness Scale were reapplied to both groups at the first and second months following the intervention, and the metabolic values, along with these scales, were measured again in the third month.
