To explore the relationship between sleep quality and health-related quality of life (HRQoL) among middle-aged and elderly adults with multiple chronic conditions and their family caregivers based on the actor-partner interdependence model, and to further explore the mediating role of depressive symptoms.
A general information questionnaire, the Pittsburgh Sleep Quality Index (PSQI), the Geriatric Depression Scale (GDS-15), and the Short Form Health Scale (SF-36) were used to survey middle-aged and elderly adults with multimorbidity and their family caregivers, and data were analyzed using actor-partner interdependence model.
Participants’ sleep quality negatively predicted their HRQoL, and depressive symptoms partially mediated the relationship between sleep quality and HRQoL (the actor effect). In addition, sleep quality in middle-aged and elderly adults with multimorbidity positively predicted caregivers’ depressive symptoms, which in turn negatively predicted their HRQoL (β=-0.25, P<0.05)(the partner effect).
Sleep quality in middle-aged and elderly adults with multimorbidity and caregivers can affect their own HRQoL through depressive symptoms. The patient’s sleep can influence the caregivers’ depressive symptoms and the caregivers’ depressive symptoms can influence the patient’s HRQoL.
