Participants
The number of participants was determined using MedCalc software, with α = 0.05, β = 0.2, MeanIn the present study, for the purpose of sampling, the research assistant attended the MS association and provided the eligible patients who referred to the association with explanations about the research plan. The patients who agreed to participate in the study filled the informed consent form. Then, with block randomization (15 blocks of 4), they were placed in one of the two intervention and control groups. The selection order of the blocks was determined using the block randomization website. Finally, equal number of people were placed in each group. A total of 60 patients were included in the study. Three people from the intervention group were excluded from the study due to not participating in the online training sessions. Finally, the data of 57 patients (27 in the intervention group and 30 in the control group) were analyzed. The study flow diagram is presented in Fig. Study flow diagram. The diagram shows the progress of the participants throughout the study. After random allocation of patients to the intervention and control groups, three patients in the intervention group did not receive the allocated intervention. Finally, the data of 27 individuals in the intervention group and 30 individuals in the control group were analyzed
