Factors influencing the psychosocial well‐being of people with dementia and their informal caregivers: A systematic review of dyadic studies

Abstract

AbstractIndividuals with dementia and their informal caregivers face significant challenges to their psychosocial well‐being, necessitating immediate attention. In spite of the prevalence of this problem, there is limited data regarding the factors that influence the dyadic psychosocial well‐being and potential actor–partner influencing mechanisms. Therefore, this review was conducted to synthesise the factors associated with the psychosocial well‐being of people with dementia and their informal caregivers. MEDLINE via EBSCOhost, CINAHL, PsycINFO, Embase and Scopus were systematically searched to identify relevant studies. Quantitative, qualitative or mixed‐method studies examining the factors influencing dyadic psychosocial well‐being outcomes were included. The quality of included studies was assessed using Joanna Briggs Institute Critical Appraisal checklists. A narrative synthesis approach was employed for data analysis. A total of 3217 records were yield, out of which 26 studies were included in the analysis. Quality of life emerged as the most extensively investigated dyadic psychosocial well‐being outcome, followed by depression. The interrelation between the quality of life for people with dementia and caregivers was observed, where individual members' quality of life was influenced by their own, partner and dyadic factors. However, there is a dearth of research exploring the mechanisms through which one member's factors exert influence on both their own and partner's quality of life within the dyad. This gap also exists for other psychosocial well‐being outcomes, such as depression and anxiety. Further research is warranted to elucidate the underlying mechanisms through which dyadic members influence their own and their partner's psychosocial well‐being.
