A structural equation model showing relationships between social support, dyadic coping and oral frailty. Active Dyadic Coping is influenced by Pressure/Communication (e1, 0.78), Supports Dyadic Coping (e2, 0.84), Dyadic Coping Proxy (e3, 0.88) and Joint Dyadic Coping (e4, 0.83). Social support impacts Objective support (e5, 0.83), Subjective support (e6, 0.90), Utilization of supported features (e7, 0.73) and Oral health-related behaviors (e8, 0.75). Oral Frailty is affected by Chewing ability (e9, 0.45), Function of deglutition (e10, 0.43), Dentures? (e11, 0.49) and Engagement? (e12, 0.13). Connections include: Active Dyadic Coping to Oral Frailty (-0.55), Social support to Oral Frailty (-0.63) and Active Dyadic Coping to Social support (0.76). The model includes various coefficients indicating the strength of relationships between these components. — Mediation model of positive dyadic coping in social support and oral frailty.
