International Journal of Clinical Case Reports, 2025, Vol.15, No.6, 283-292 http://medscipublisher.com/index.php/ijccr 288 5.3 Results of pilot projects or case-based stress intervention practices A randomized controlled trial of intervention using mobile phone applications independently showed that after three months of follow-up, participants' stress and depressive symptoms were significantly reduced, and their emotional health, optimistic mindset and social support levels continued to improve (Sui et al., 2022). This result confirms the value of digital intervention programs when they are adapted to caregivers' time and preferences. Studies on mindfulness intervention programs have found that mindfulness-based cognitive therapy (MBCT) may be more effective in reducing stress for caregivers than mindfulness-based stress reduction therapy (MBSR). The intervention plan should be adjusted in combination with the actual situation of the caregivers and the elderly being cared for, so as to maintain the intervention effect (Gimm et al., 2022). 6 Support Mechanism and Intervention Effect Analysis 6.1 Evaluate the implementation effects of various support mechanisms After the implementation of the family-centered care support approach for disabled elderly people, the conditions of both caregivers and the elderly have improved significantly. Comprehensive care models like the SMART system are willing and convenient for the elderly to use. They can also customize exclusive care plans through online platforms and arrange various care affairs properly (Guo et al., 2025). The assistance measures led by nurses and carried out in the elderly people's homes have also achieved good results. Actual experimental data show that after 12 months of follow-up observation, the quality of life of caregivers has improved, and the corresponding utility score has also increased (Rico-Blazquez et al., 2021). Whether social support is sufficient and the ability of caregivers themselves is strong are the key factors influencing the relationship between the severity of disability in the elderly and the quality of family care. Studies have shown that increasing social support and providing targeted training for caregivers can directly improve the level of care and alleviate the adverse effects brought by elderly disability. However, the effectiveness of these support mechanisms is often influenced by regional differences. For example, whether the services in different places are considerate, whether the policy support is strong, and whether the medical and social health systems are well combined will all have an impact on it (Zhang and Yang, 2024; Yu et al., 2025). 6.2 The effectiveness, limitations and influencing factors of stress intervention measures Social psychological intervention, especially mindfulness-based intervention (MBI) and cognitive behavioral therapy (CBT), has become the most effective strategy for reducing the burden and stress of caregivers. Network meta-analysis shows that MBIs is particularly beneficial for caregivers of patients with cognitive impairment, while CBT is very effective in the family environment (Chen et al., 2025). Web-based intervention measures can reduce depression and anxiety among caregivers. Despite these achievements, there are still some deficiencies at present. The effect of intervention methods is influenced by factors such as the educational level of caregivers, their perceived health status, the severity of disability of the elderly being cared for, and whether they can obtain social support (Yu et al., 2025). Moreover, it is still uncertain whether the intervention effect can be maintained over time. Studies have pointed out that after the initial intervention ended, the previous benefits gradually weakened (Khiewchaum et al., 2024). 6.3 Challenges and directions for improving the long-term operation of the nursing support system There are still many problems that remain unsolved to ensure the long-term and stable operation of the nursing support system. For example, relevant policies are not unified, supporting facilities cannot keep up, the connection between medical services and social care is not close, and society does not attach enough importance to the labor and value of nursing staff, etc. (Zhang and Yang, 2024; Yu et al., 2025). In addition, the care needs of disabled elderly people vary, and there must be dedicated corresponding services. However, current systems often fail to provide personalized assistance in a timely manner, lacking both continuous feedback and comprehensive support (Guo et al., 2025).
