Sample characteristics
The final sample of 80 respondents was randomly assigned into two groups of 40, intervention and control subjects. The youngest participant in this study was 41 years old and the oldest was 65 years old, and the mean age of the participants was 56.60 ± 5.546 years. According to the Mann-Whitney test, there was no significant difference between the two groups in terms of age (P = 0.68). The majority of the subjects in both groups were male (61.3%) and married (83.8%). Most participants in the intervention and control groups (52.5%) had a diploma and were retired (32.5%). The results of the chi-square test showed that there was no significant difference between the two groups in terms of demographic characteristics including gender, marital status, education level, and job (P > 0.05). Details of the respondents are presented in Table The BMI of the participants was reported 25.65 ± 2.896. The means of their BMI were 25.85 ± 2.88, and 25.43 ± 2.92 in the intervention and control groups, respectively. The results showed no significant difference between the two groups in terms of BMI (Z=-4.63, P = 0.67) (Table According to the results shown in Table As shown in Table This study indicated that there was no statistically significant difference between the resilience mean scores of the two groups before the intervention (P = 0.92). On the other hand, the resilience mean score of patients in the intervention and control groups was statistically significant after the intervention (P < 0.001). The mean score of resilience inpatients of the intervention group before and after the intervention was significantly different (P < 0.001). There was a statistically significant difference in the resilience mean scores of patients in the control group before and after the intervention (P = 0.02); however, this difference was reduced in the control group.
