The block randomization method is performed by the statistical consultant as follows: randomization is performed in three groups: unified transdiagnostic treatment, application of Roy's adaptation model and control. First, a list of eligible individuals is provided and coded. We first code the groups in Latin letters as follows: A = unified transdiagnostic treatment, B= application of Roy's adaptation model and C = control group. In this study with three groups A, B, and C, we create the following six groups and assign a number from 1 to 6 to each group: ABC-ACB-BAC-BCA-CAB-CBA, Then, using the table of random numbers, we contract that if the numbers 1, 2, 3, 4, 5, and 6 appear in order, one of these blocks will be selected, and if another number appears, we will assume it to be void and move on to the next selection. We have obtained a random sequence of numbers with a table of random numbers that for each number we consider the desired order of assignment. In this way, the number of people in the groups will be approximately equal.
