Finding showed majority of participants (71.9%) in both groups were within the age range 45-60. In the both groups (62.7%) were female and majority of participants (58.7%) base of education level in both groups were bachelor degree, another demographic characterized showed in Table 1. The Chi-square test showed that the intervention and control groups were no significant different base of demographic variables, P < 0.05, showed in Table 1. Findings indicated that care plan based on Roy adaptation model can influence maladaptive behaviors of patients with heart failure in all physiologic, self-concept, role function and interdependence modes, so that significant reduction was observed in the number of maladaptive behaviors after intervention compared to before intervention.
Results of current research showed that in relation with mean score fatigue and daily activities of life were not significant in intervention and control group before intervention, while it was significant after intervention P < 0.05. Pair t-test showed mean score of fatigue and daily activities in intervention group before and after intervention was significant P < 0.01, so that in the intervention group the mean score of fatigue were significantly decreased after intervention (3.5 ± 1.7) compared to before intervention (6.2 ± 2.2).Also in the intervention group the mean score of daily activities were significantly increased after intervention (62.2 ± 12.8) compared to before intervention (45.3 ± 11.2), showed in Table 2.T-test showed significant difference between intervention and control groups in terms of mean score of fatigue and daily activities, so that the intervention group had significantly lower mean scores in fatigue and higher daily activities after intervention compared to the control group P < 0.01, shows in Table 3.
The ANOVA test showed there was a significant relationship between the duration of time heart failure disease and frequency of hospitalization with fatigue in both intervention and control groups P  ≤ .05, so that, the mean score of fatigue was less than other participants in patients hospitalized twice a month because of the nature of the disease and their duration of heart failure was 5 years or less. The ANOVA test showed there was a significant relationship between the duration of time heart failure disease and frequency of hospitalization with daily activities level P  ≤ .05, so that, the mean score of daily activities level in the participants both control and intervention groups was more than other participants in the first 5 years of heart failure and hospitalization twice per month. The result showed no significant relationship was observed between another demographic characterized and variables of fatigue and daily activities in both groups.
