The age variable is expressed separately as mean and standard deviation for the control and intervention groups. The average age was 52.83 ± 8.71 years in the control group and 52.66 ± 9.23 years in the intervention group, without a statistically significant difference (P = 0.943).The findings indicated that most patients were male (56%), married (78%), and urban residents (98%). There were no significant differences between the two groups regarding demographic variables such as age, marital status, place of residence, educational attainment, and history of renal transplants (P > 0.05). However, the two groups differed significantly in terms of some demographic features, such as employment status (P = 0.009), economic status (P = 0.011), and the number of dialysis sessions (P = 0.001) (Table 
Distribution of frequency and percentage of demographic characteristics of patients in intervention and control groupsAccording to the results, there were significant differences between the two groups before the intervention concerning the scores of some specific dimensions of quality of life, such as renal complications, dialysis, patient satisfaction, and quality of social interactions. The distortive effects of these variables were analyzed through ANCOVA. Given the P-value (P = 0.001), it could be concluded that the intervention caused intergroup differences, and the abovementioned factors did not affect the results. The independent 
Intergroup comparison of specific aspects of quality of life of patients before and after intervention in intervention and control groups

Concerning the general dimensions of quality of life before the intervention, there were significant differences between the two groups regarding some dimensions, such as energy level, emotions and feelings, role limitation due to emotional and physical problems, and general health. The distortive effects of these variables were analyzed through ANCOVA, which indicated that the intervention caused intergroup differences and that the above mentioned factors did not affect the results. According to the independent
