The results of this study showed that QOL scores for patients in the control group exhibited no statistically significant difference before and after routine care. However, in the intervention group, QOL scores significantly improved across all dimensions, enhancing the patients' overall QOL. Family caregivers’ QOL scores did not show a statistically significant difference in the control group, with declines observed in aspects like emotional problems and mental health. Conversely, in the intervention group, QOL scores significantly improved across all dimensions, suggesting that the SSP effectively enhanced caregivers' overall QOL.
In terms of resilience, family caregivers in the control group exhibited no significant changes in resilience scores before and after the intervention, with some decline observed. In contrast, resilience scores significantly improved in the intervention group, demonstrating the effectiveness of the SSP in enhancing caregivers' resilience.
These findings are consistent with those of Zangbari et al., who reported a statistically significant improvement in QOL scores following SSP intervention (P < 0.001) in the intervention group, while no significant differences were observed in the control group (
25). Similarly, Yadegarfar demonstrated that proper education significantly improved QOL in stroke patients (
26).
Pitthayapong et al. supported the idea that family caregivers participating in post-stroke care intervention programs acquired essential caregiving skills, improving work efficiency and reducing stroke complications in patients (
9). Amraei et al. also found that educational programs for hemiplegic stroke patients reduced caregiver stress, anxiety, and depression, increasing their awareness and ability to adapt to caregiving roles (
27). This enhanced their communication with patients and improved their QOL.
Behzadi et al. noted that caregiver resilience improves after support program interventions, influenced by factors like knowledge, social support, and family structure (
28). Similar supportive programs for chronic conditions like mental disorders and heart failure have demonstrated improved long-term resilience for caregivers, reducing caregiving pressure and enhancing QOL. Fathani's study also confirmed that SSP interventions improve QOL for caregivers of heart patients (
29).
The independent variable in this study was the SSP, with QOL as the dependent variable and resilience as an intermediate variable. A structural equation model was established to analyze and verify the causal relationships between these three variables. The results showed that family QOL had a direct positive effect on caregivers’ QOL and could also indirectly affect it through resilience. Resilience itself had a direct positive effect on caregivers’ QOL. Acting as an intermediary variable, resilience played a significant dual role by mediating the relationship between family QOL and caregiver QOL. In the process of adaptation and acceptance among stroke patients, resilience played a positive role during the self-psychological adjustment stage, serving as a source of strength for psychological transformation (
30). Resilience, recognized as a protective factor for individual psychological well-being, has been identified as a mediating variable in numerous research studies (
31,
32). This study further demonstrated that resilience had a practical intermediary effect, reinforcing its potential as a focus for nursing interventions.
The limitations of this research include non-cooperation from some caregivers and stroke patients during data collection, personal challenges when answering the questionnaire, unconscious biases in responses, and insufficient attention to cultural conditions. Despite these challenges, this study concludes that SSP significantly improves resilience and QOL for family caregivers, offering a practical framework for better caregiving outcomes.
5.1. Implications
This randomized controlled trial demonstrates SSP effectiveness for caregivers of stroke patients, with implications for nursing practice, research, policy, and education. The program improves QOL, resilience, and outcomes for patients while reducing caregiver burden. The findings highlight the need for resource investment and SSP integration into nursing practice.
The study recommends conducting additional clinical trials to evaluate SSP's impact on caregivers of other chronic diseases. Strategies such as practical training sessions and psychological support should be developed to foster family caregiver involvement, enhance their awareness, and ensure attention to cultural contexts. Healthcare managers should use these findings to design effective caregiver support strategies. The program developed in this study should be applied to patients and caregivers with similar conditions to maximize its benefits.
5.2. Conclusions
The findings indicate that implementing an SSP for family caregivers of stroke patients is effective in enhancing the well-being of both caregivers and patients. The program provides essential support, training, and guidance, enabling caregivers to manage daily activities and address mental, emotional, physical, and psychological challenges effectively. This study emphasizes the importance of family participation in patient care and underscores the value of nursing theories like Orem's self-care theory.
