Objective The aim of this study is to analyze the impact and significance of Alzheimer's disease (AD) patients on caregiver burden, psychological status and quality of life from the perspective of Precision Psychological Capital Intervention (P-PCI). Methods Patients diagnosed with AD and their caregivers from our hospital between May 2019 and October 2022 were enrolled in the study, and all patients underwent conventional treatment for AD. The patients and their caregivers were divided into a control group (n=37), who underwent usual care, and an observation group (n=41), who underwent P-PCI on top of that, using a randomized numerical table. The psychological status of the carers was assessed by the positive psychological-capital questionnaire (PPQ), the readiness of the carers was assessed by the caregiver preparedness scale (CPS), the caring capacity of the carers was assessed by the family caregiver task inventory (FCTI), the carer burden was assessed by the caregiver burden inventory (CBI), the carer's social support was assessed by the social support rating scale (SSRS), and the WHOQOL-BREF assessed patient/carer quality of survival. Results After the intervention, compared with the Control group, the observation group: (1) showed a significant upward trend in PPQ dimensions: PPQ dimensions: self-efficacy, optimism, resilience, and hope, as well as the total score; (2) showed an upward trend in CPS, and an even more pronounced downward trend in FCTI; (3) showed a significant upward trend in CBI dimensions: time-dependent, developmentally limited, physical, social, and emotional load scores, as well as a significant downward trend in the total score; (4) showed a significant upward trend in all SSRS dimensions: a more pronounced upward trend in the objective support, subjective support, and utilisation of support scores, as well as in the total score; (5) showed a significant upward trend in WHOQOL-BREF score in caregiver's and patient's of all dimensions: trend in the physiological, psychological, social relationship, and environmental were more pronounced upward. Conclusion P-PCI can reduce the burden of caregiving and improve the quality of life of caregivers of patients with AD by effectively enhancing their psychological capital, which in turn leads to improved quality of life for patients.
