The mean age of the case group was 58.93 ± 11.12 and 54.53 ± 9.06 for the control group. Mean duration of the disease was reported 7.63 ± 3.82 years in case group and 6.16 ± 2.13 years in control group. According to the outcome evaluated by Mann-Whitney and Chi-square tests, both groups had the same education level. Moreover, no significant difference was observed between the case and control groups in terms of demographic factors (Table 1). The results of t-test (independent samples t-test) were calculated based on the differential between means of the self-regulations with regard to a pretest and posttest taken from case and control groups (first P value) (Table 2). As a result, mean of self-regulation training was higher in case than the control group (P = 0.001).
