The Effect of Mindfulness-Based Psychoeducation

This study is a randomized controlled experimental study conducted to determine the effect of mindfulness-based psychoeducation on levels of mindfulness, cognitive defusion, and depression in patients with depression. The sample of the study will consist of 60 patients (30 experimental, 30 control) diagnosed with major depression, recruited from a state hospital. Mindfulness-based psychoeducation will be applied to the experimental group once a week for a total of 8 weeks in the form of group sessions. No intervention other than routine treatment will be applied to the control group. The primary questions that the study aims to answer are as follows: Does mindfulness-based psychoeducation increase levels of mindfulness and cognitive defusion in depression patients? Does mindfulness-based psychoeducation decrease levels of depression in depression patients?

In this research, the sample size calculation was performed using the G Power program by conducting a priori power analysis. Previous studies were reviewed and using the Beck Depression Inventory, expected confidence intervals were determined. With a confidence interval of α=0.05 and a test power (1-β) of 0.95, with an effect size of d=0.9632193, a total of 60 patients were calculated, with 30 patients in the experimental group and 30 patients in the control group. Participants included in the study will be assigned to experimental or control groups using block randomization.
