Introduction

Formulating and implementing mental health policy is foundational to public mental health. The implementation of mental health policy varies in low- and middle-income countries (LMICs), with some countries having better implementation outcomes than others. Low implementation poses challenges relating to addressing the high burden and wide treatment gaps of mental health conditions. While different implementation strategies are applied to implement mental health policy in different contexts, there is little knowledge of what category of strategies are being used and how and why their implementation produces varied outcomes. To this end, we propose to conduct a realist synthesis to explain how, why, for whom, and under what health system conditions certain policy implementation strategies work or not in LMICs.

Methods and analysis

This paper will detail the protocol on conducting a realist review of the literature on mental health policy implementation in LMICs. Realist reviews/syntheses are theory-driven reviews designed to formulate and test (confirm, refute, or refine) initial programme theories to explain how, why, for whom and under what contexts a programme, intervention or policy works as intended or not. Theory is built by exploring and abstracting context-mechanism-outcome (CMO) configurations in the data. These CMO configurations are identified through retroductive theorizing, a mechanism-centred approach to theory development. We will adopt these steps to guide the process of realist synthesis: i) identify the research question, clarifying the scope of the review and formulating the initial programme theory (ii) conducting background searches in PubMed, PsycINFO, Africa-Wide Information, African Index Medicus (AIM), CINAHL and Scopus databases, and grey literature (iii) appraising the quality of studies and data extraction and (iv) synthesising data.

Registration

The review is part of a realist evaluation exploring mental health policy implementation in LMICs and is registered under PROSPERO (registration number: CRD42024580312). Findings will inform the development of initial mental health policy implementation programme theories explaining why and how mental health policy implementation in LMICs works.

Abstract:

Realist synthesis is a recognized methodological approach to evidence synthesis to inform evidence-based health policy and practice. The implicit assumption behind research synthesis is that the evidence it generates should be generalizable––drawing broad inferences from specific observations. While this understanding is generally shared among social scientists, tensions exist between having generalizable evidence and how this evidence can be useful in specific contexts. This paper considers the role of mechanism-based middle-range theories obtained from realist synthesis in bridging specificity to context and generalizability. Retroductive theorizing in realist synthesis helps to identify ideas about mechanisms related to the phenomenon embedded in the social and organizational contexts that could, in principle, have a much broader application. Also, because mechanism-based middle-range theories are linked to contextual features, they capture contextual nuances to enhance evidence implementation. We conclude that middle-range mechanisms provide an opportunity to achieve generalizability and contextualization in implementation science.

Abstract:

A realist review is a theory-driven approach to synthesizing evidence based on the realist philosophy of science. Realist reviews are conducted to provide the policy and practice community with a rich, detailed and practical understanding of complex social interventions that will likely be of much more use to them when planning and implementing programmes. Robust realist reviews must balance philosophical engagement, methodological rigour and relevance to practice. Nevertheless, they have been criticized for being more philosophically inclined and less methodologically robust, with findings that have little implication for practice. Using the philosophy/epistemology➔ methodology➔ theory➔ practice concept flow, we report how we balanced philosophical principles and practical insights in a recently conducted realist review on participatory practices that impact the benefits of non-communicable disease research and interventions in low- and middle-income countries. If realist reviews are not comprehensible enough for these practitioners, their utility and relevance may suffer from being limited to a specialist cohort of academics. We propose that realist review findings and outputs must be framed and communicated to meaningfully engage practitioners without undertaking translational efforts.

Abstract:

Introduction

Community engagement and participatory research are widely used and considered important for ethical health research and interventions. Based on calls to unpack their complexity and observed biases in their favour, we conducted a realist review with a focus on non-communicable disease prevention. The aim was to generate an understanding of how and why engagement or participatory practices enhance or hinder the benefits of non-communicable disease research and interventions in low- and middle-income countries.

Methods

We retroductively formulated theories based on existing literature and realist interviews. After initial searches, preliminary theories and a search strategy were developed. We searched three databases and screened records with a focus on theoretical and empirical relevance. Insights about contexts, strategies, mechanisms and outcomes were extracted and synthesised into six theories. Five realist interviews were conducted to complement literature-based theorising. The final synthesis included 17 quality-appraised articles describing 15 studies.

Results

We developed six theories explaining how community engagement or participatory research practices either enhance or hinder the benefits of non-communicable disease research or interventions. Benefit-enhancing mechanisms include community members’ agency being realised, a shared understanding of the benefits of health promotion, communities feeling empowered, and community members feeling solidarity and unity. Benefit-hindering mechanisms include community members’ agency remaining unrealised and participation being driven by financial motives or reputational expectations

Conclusion

Our review challenges assumptions about community engagement and participatory research being solely beneficial in the context of non-communicable disease prevention in low- and middle-income countries. We present both helpful and harmful pathways through which health and research outcomes are affected. Our practical recommendations relate to maximising benefits and minimising harm by addressing institutional inflexibility and researcher capabilities, managing expectations on research, promoting solidarity in solving public health challenges and sharing decision-making power.

Abstract:

The realist review/synthesis has become an increasingly prominent methodological approach to evidence synthesis that can inform policy and practice. While there are publication standards and guidelines for the conduct of realist reviews, published reviews often provide minimal detail regarding how they have conducted some methodological steps. This includes selecting and appraising evidence sources, which are often considered for their ‘relevance, richness and rigour.’ In contrast to other review approaches, for example, narrative reviews and meta-analyses, the inclusion criteria and appraisal of evidence within realist reviews depend less on the study's methodological quality and more on its contribution to our understanding of generative causation, uncovered through the process of retroductive theorising. This research brief aims to discuss the current challenges and practices for appraising documents' relevance, richness and rigour and to provide pragmatic suggestions for how realist reviewers can put this into practice.

Abstract:

Adolescents living with HIV (ALHIV) need support from family, peers and health workers to remain on antiretroviral therapy and achieve and sustain viral suppression. This paper qualitatively explores the implementation of a psychosocial support intervention (PSS) in five primary health care facilities in the Ehlanzeni district, South Africa. Data were collected through key informant interviews and focus group discussions with ALHIV on ART. Data analysis employed inductive thematic analysis. Informed consent was obtained prior to all data collection. The PSS intervention facilitated full disclosure of HIV status to adolescents, supported treatment adherence through health education, peer support, health care provider- and client relations, and quick access to health service delivery. However, COVID-19 restrictions and regulations challenged the implementation of the intervention. The PSS intervention showed promise to support adolescent’s adherence and retention in care. We recommend innovative approaches to account for systemic disruptions, as evidenced by the COVID-19 pandemic.

Abstract:

Differentiated service delivery for HIV treatment seeks to enhance medication adherence while respecting the preferences of people living with HIV. Nevertheless, patients’ experiences of using these differentiated service delivery models or approaches have not been qualitatively compared. Underpinned by the tenets of descriptive phenomenology, we explored and compared the experiences of patients in three differentiated service delivery models using the National Health Services’ Patient Experience Framework. Data were collected from 68 purposively selected people living with HIV receiving care in facility adherence clubs, community adherence clubs, and quick pharmacy pick-up. Using the constant comparative thematic analysis approach, we compared themes identified across the different participant groups. Compared to facility adherence clubs and community adherence clubs, patients in the quick pharmacy pick-up model experienced less information sharing; communication and education; and emotional/psychological support. Patients’ positive experience with a differentiated service delivery model is based on how well the model fits into their HIV disease self-management goals.
