The block randomization method is performed by the statistical consultant as follows: randomization is performed in three groups: Spirituality Therapy, Acceptance and Commitment therapy, and control: First, a list of eligible individuals is provided and coded. In block randomization, the number of participants in all groups will be very close together by making blocks of sequences so that the same number of participants are assigned to study groups within each group. We first code the groups in Latin letters as follows:
A = Spirituality Therapy, B = Acceptance and Commitment therapy, and C control group
In this study with three groups A, B and C we create the following six groups and assign 1 to 6 each:
ABC-ACB-BAC-BCA-CAB-CBA
Then, using the random number table, we choose one of these blocks whenever the numbers 1, 2, 3, 4, 5, 6 appear, and if the other number appears, consider null and go to the next choice. . In fact, we have obtained a random sequence of numbers with a random number table that we consider the order of assignment for each number. This way the number of people in the groups will be approximately equal.
