Abstract: Objective: Based on the actor-partner interdependence model, this study aims to explore the relationships between self-efficacy, resilience, social support, and Quality of Life (QOL) among elderly patients following hip fracture surgery and their family caregivers, so as to provide a theoretical basis for clinical interventions. Methods: From July to December 2024, 221 pairs of elderly patients who had undergone hip fracture surgery and their caregivers, who were conveniently selected from the outpatient clinics of three tertiary grade A hospitals in Qingdao for reexamination, were surveyed by using the General Information Questionnaire, the Self-Efficacy for Rehabilitation Exercise Scale, the General Self-Efficacy Scale, the Social Support Rating Scale, the 10-item Connor-Davidson Resilience Scale, and the Short Form 12 Health Survey. An actor-partner interdependence model was constructed to analyze actor effects and partner effects at the dyadic level. Results: In terms of the actor effect, both the self-efficacy (β=0.697; β=0.536), psychological resilience (β=0.441; β=0.599), and social support (β=0.628; β=0.613) of patients and caregivers influenced their own QOL (all P<0.05). In terms of the partner effect, the QOL of patients was affected by the psychological resilience (β=0.300) and social support (β=0.309) of caregivers (all P<0.05), while the QOL of caregivers was influenced by the psychological resilience (β=0.711) and social support (β=0.336) of patients (all P<0.05). Conclusion: The QOL of elderly patients after hip fracture surgery and their caregivers has an interactive influence on the psychological resilience and social support of both. This indicates that nurses can conduct interventions based on a dyadic perspective, taking into account the psychological resilience and social support of patients and their caregivers, so as to effectively enhance the QOL of both parties.
