In this research, randomization into three PLISSIT intervention groups (35 people), sexual health model group (35 people) and control group (35 people) will be done by simple randomization method.Random numbers were used to randomize and assign individuals to groups; randomization using Excel software is as follows: First, in a column, groups are entered as A, B, C, and below, because the number of samples in each group is set to 35 (including the sample fall), so 35, B, A, C must be as follows. And they come in regularly. In the opposite column, random numbers are generated using the RAND command. In the next step, using the sort command, random numbers generated from small to large or vice versa are arranged, which causes the order of the groups, C, A, B, to change. Using the new order, people are assigned to different groups.
