Health literacy interventions for informal caregivers: systematic review

Abstract

Aim The aim of the systematic review was to identify conceptual models and interventions designed to improve health literacy in caregivers of adults with a chronic disease/disability.

Methods MEDLINE, CINAHL, PsycINFO and Embase were searched for relevant literature. Articles were included if they focused on adults who provided informal care to someone aged 18+ with a chronic disease/disability. Quantitative studies were included if they reported an intervention designed to improve caregiver health literacy (CHL) and assessed outcomes using a validated measure of health literacy. Qualitative and mixed method studies were included if they described a conceptual model or framework of CHL or developed/assessed the feasibility of an intervention. Study quality was appraised using the Mixed Methods Assessment Tool.

Results Eleven studies were included. Five studies used pre–post design to assess outcomes of an intervention; four described intervention development and/or pilot testing; two described conceptual models. Two of five studies reported pre–post intervention improvements in CHL; one reported an improvement in one of nine health literacy domains; two reported no improvements following intervention. Interventions predominantly aimed to improve: caregiver understanding of the disease, treatment and potential outcomes, day-to-day care, self-care and health provider engagement. Few interventions targeted broader interpersonal and health service factors identified as influencing CHL.

Discussion Evidence on the development and assessment of comprehensive CHL interventions is scarce. Recommendations include the development of interventions that are guided by a CHL framework to ensure they address individual, interpersonal and health service/provider factors that influence CHL.
