Impact of Community Interventions on the Social Representation of Depression in Rural Gujarat

Systematic review of interventions to reduce mental health stigma in India

BACKGROUND

Stigma is a barrier for help-seeking, mental health service access, and contributes to the mental health treatment gap. Because the mental health treatment gap is greatest in low- and middle-income countries, it is vital to identify effective strategies to reduce stigma in these settings. To date, there has been a lack of synthesis of findings from interventions to reduce stigma related to mental disorders within India.

METHOD

A systematic review was conducted to provide an overview of the characteristics and effectiveness of stigma reduction interventions studies in India. PubMed, Embase and PsycINFO databases were searched for literature published up to 30th June 2020.

RESULTS

From a total of 1,984 articles identified, only 9 were eligible for final inclusion, published between 1990-2020. No study was found from North, North-East, Central or East India. Most stigma-reduction interventions were multi-level, that is, using a combination of intra-personal, inter-personal and community level strategies to target changes in outcomes of individuals, environments and community groups. Three studies focused on health and stigma-related changes at the organisational/institutional level. No interventions focused on the governmental/structural level. There were only two randomised controlled trials, and two studies focused on all three stigma components of knowledge, attitudes and behaviour. Most interventions were delivered to community members. None focused on mental health professionals as intervention delivery target.

CONCLUSION

There is a need for the development of comprehensive, culturally acceptable evidence-based interventions that act at multiple levels, and involve a mixture of various stigma reducing strategies with multiple target groups.

Health Literacy Interventions to Improve Health Outcomes in Low- and Middle-Income Countries

Background:

Health care systems in many low- and middle-income countries (LMICs) face considerable challenges in providing high-quality, affordable, and universally accessible care. Feasible solutions to these issues require health literacy (HL) interventions for people who live in LMICs. Low HL is a significant problem in many LMICs because of the low levels of general literacy and poorly resourced and functioning health systems. A comprehensive understanding of HL interventions is essential to determine whether these interventions meet the health information needs of people who live in LMICs and to develop other effective HL interventions specifically for people who live in LMICs, improve health outcomes, and reduce inequalities.

Methods:

A medical research librarian developed and implemented search strategies to identify relevant evidence. Included studies needed to contain HL in LMICs component to understand or evaluate HL interventions that target people who live in LMICs. Two reviewers selected studies, conducted quality assessments, and extracted data by using standard forms. Discussion or third-party adjudication resolved disagreements. The collected data include the design of the study, type of HL intervention, target audience, theoretical influences, approaches to evaluating the intervention delivered, intervention received, intervention fidelity, intervention reach, data analysis, and study outcomes.

Key Results:

The reviewers systematically analyzed the data from 23 published research studies, including 20 quantitative, 1 qualitative, and 2 mixed-method studies, on HL interventions to improve the health outcomes in LMICs. The various HL interventions for different groups of the population depend on the health outcomes of the study. The reviewers identified four themes: traditional HL interventions, art-based HL interventions, interactive learning strategies, and technology-based HL interventions. The researchers of a few studies also used multicomponent interventions to improve the HL of the population.

Discussion:

Despite global improvements in health indicators over time, such as decreased mortality and morbidity, significant challenges remain regarding the quality of the delivery of health care in many LMICs. All of the HL interventions were effective and significantly improved the knowledge and awareness of the population. However, based on the literature review, the reviewers found significant evidence that only a limited number of HL interventions are delivered through innovative and technological learning strategies. In addition, the sustainability and scalability of these interventions is not clear. Therefore, future research on sustainability measures for effective HL interventions in LMICs is still needed.
