The Relationship Between Dyadic Type and Quality of Life in Patients With Stroke: Mediating Effects of Depression, Anxiety, and Health-Promoting Behaviors.

This study aimed to identify the mediating effects of depression, anxiety, and health promoting behaviors (HPB) on the relationship between dyadic types and quality of life (QoL) in patients with stroke. This study used a cross-sectional correlational study design. Participants were 147 dyads (outpatients and their caregivers) from the department of neurology at a university hospital in Seoul, South Korea. The dyadic types were collaborative-oriented (37.4%), patient-oriented (32.7%), incongruent (20.4%), and caregiver-oriented (9.5%). The caregiver-oriented type had higher depression and anxiety scores, and the collaborative-oriented type had higher HPB. Patient- and collaborative-oriented types had higher QoL. In a hierarchical regression analysis, the factors influencing QoL were language deficit, modified Rankin Scale score, hyperlipidemia, depression, and HPB. In addition, depression, anxiety, and HPB had partial mediating effects on the relationship between dyadic type and QoL. Therefore, the dyadic type should be evaluated together when evaluating QoL along with depression, anxiety, and health-promoting behaviors, since the dyadic type influences QoL. In addition, interventions considering dyadic type are required, and these strategies may contribute to improving HPB and QoL in patients with stroke.
