Randomization will run by using the Software Allocation Random. We will use the simple randomization method to assign subjects to three study groups. We will assign a unique number to every member of our study's sample (from 1 to 45). An independent researcher makes random allocation codes using computer-generated random numbers. Then, we will use the random allocation generator software to randomly assign each number to experimental groups and control groups.

The study was single blind. The patients in three groups (cognitive-behavioral therapy and integrated meta-diagnostic therapy and control group) did not know about the type of intervention that was performed. Also, the data analyst and the person conducting the assessments will be blind to the specific participant’s group.
