Mental health and disability research in Ghana: a rapid review

The objective of this rapid review was to explore the current evidence base for mental health and disability research in Ghana. The PRISMA-ScR (Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews) checklist was followed. Online databases were used to identify primary studies, systematic reviews, meta-analyses, rapid reviews, or guidelines published between 2010 and 2020. All relevant published (both peer-reviewed articles and grey literature) on mental health and/or disability research conducted in or on Ghana between 2010 and 2020 were included in this review. 4,791 articles were identified in the initial search. After the removal of duplicates, followed by title and abstract screening, 930 articles were selected for full-text review. An additional 8 articles identified from reference lists of included articles were also included in full-text review. After review, 375 articles were selected for inclusion; 234 (62%) were on mental health while the remaining 141 (38%) were on disability. There is an increasing trend in the absolute number of mental health and/or disability studies. Most of the mental health studies included in this review were either observational quantitative studies (n=132; 56%) or observational qualitative studies (n=79; 34%). There were very few interventional studies (n=6; 3%). A similar finding was noted for the disability studies. External funding accounted for 51% of mental health articles. Although there was a steady year-on-year increase in the absolute number of mental health and/or disability studies conducted between 2010 to 2020, there is a need for more intervention studies to evaluate what mental health and/or disability interventions work, for whom, and under what circumstances. These should include evaluations of the cost, benefits, effectiveness, and acceptability of various interventions for policy and planning. Further, there is a need for the Ministry of Health to prioritize research funding for mental health and disability and enhance technical and methodological capacity of researchers to conduct disability and mental health research in Ghana.
