A mixed-method systematic literature review of health literacy interventions for people with disabilities

Abstract

Aims: To identify the components and characteristics of health literacy interventions for people with disabilities and to explore the outcomes in terms of health literacy competencies.

Design: A mixed-method systematic literature review.

Review methods: The search results were reported based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. The quality appraisal was guided by the Mixed Methods Appraisal Tool. The contents of each intervention were mapped to the health literacy intervention model and the outcomes were annotated using the integrated model of health literacy.

Data sources: The literature search was conducted using several electronic databases, including PubMed, EMBASE, CINAHL, Cochrane library and PsycINFO in December 2022.

Results: Ten studies were selected for this systematic literature review. Seven studies were quantitative, two were qualitative and one was a mixed-methods study. The four components of the health literacy interventions included empowering individuals with low-health literacy (n = 10), strengthening individuals' social support system (n = 3), improving communication with health professionals (n = 1) and reducing barriers to access health systems (n = 3). No intervention addressed improving health professionals' health literacy competencies. Health literacy competencies identified as outcomes in the studies included access (n = 1), understand (n = 7), appraise (n = 1) and apply (n = 9) the health information.

Conclusions: The significant findings of this systematic literature review provide baseline data and evidence for developing health literacy interventions for people with disabilities. However, this review demonstrates that only a handful of intervention studies have addressed the low-health literacy of people with disabilities. Further and more rigorous interventions addressing health literacy for people with diverse disabilities are warranted.

Impact: This review provides insights into how health literacy interventions can be tailored to the type of disability. Further, efforts should be expanded to comprehensively promote all the four core competencies of health literacy to reduce health disparities for individuals living with disabilities.
