This integrative review aims to explore the current state of dyadic interventions in older people with chronic diseases and to review how these interventions are developed and conducted. 'Older people' and 'dyadic intervention' were searched in six databases to include studies published before August 2021. The constant comparison method was used for data synthesis, combined with the Joanna Briggs Institute (JBI)1 and mixed methods appraisal tool (MMAT)2 to assess the quality of the literature. Nineteen studies were included and could be divided into four types in which caregivers could be seen as subordinators, directors, cooperators and collaborators. Dyadic interaction could be observed in all studies, including dyad coled, patient-led, and caregiver-led interactions. The outcome indicators included patient-, caregiver-, dyad-, and family-related indicators. It is important not only to include the dyad but also to consider the dyadic interactions. In the future, dyadic intervention can be guided by matching dyadic theories. NO PATIENT OR PUBLIC CONTRIBUTION: This study is an integrative review; the study population was not directly contacted. Data from included studies were analysed and interpreted.
Keywords: Caregiver; Chronic disease; Dyadic interaction; Dyadic intervention; Older people.
