Randomized randomized clinical trial method
In order to sample and randomize the block randomization method, it is to ensure that exactly the same number of participants enter the intervention and control group at consecutive but equal intervals, in order to hide the allocation, the size of the blocks, Will be considered heterogeneous. (To select a sample after preparing a list of patients referred to Amirabad Diabetes Clinic in Tehran, contact them, select 75 people who wanted to participate in the treatment using the available sampling method, based on the inclusion criteria And were randomly assigned to three groups (hope therapy group = 25 people, spiritual therapy group = 25 people and control group = 25 people). For this purpose, participants first complete the research questionnaires, then blood tests are performed to perform tests for glycosylated hemoglobin and fasting blood sugar (fasting sugar should not exceed 135 mg / dL, hemoglobin A and C should not exceed 8%).
In other words, the invitation to participate in the study project will be distributed through a brochure and announcement at the Amirabad Diabetes Center in Tehran. After examining the entry conditions based on what was said above, they are divided into three groups of 25, because we have three study groups, we name each group with the English letters a, b, c. We write the letters a, b, c in three envelopes or on three pieces of paper and close them and mix them like lots so that it is not clear what we have written in which one. By announcing the candidacy of each person to enter the study, we randomly remove one of the envelopes and attribute the person to that group according to the letter inside it. When the second person arrives, we select one of the remaining two envelopes and assign it to that person. Then the third person will be assigned to the group written in the envelope that were not selected in the previous two selections. Work continues until the required number of samples is completed in all three groups.
