A systematic review of the effectiveness and implementation readiness of psychosocial interventions for psychosis in South Asia

BACKGROUND

Little is known about the effectiveness and implementation of psychosocial interventions for psychosis in low- and middle-income countries (LMICs). In South Asia, specialist psychiatric resources are scarce. Support for psychosis often falls on the family or caregiver which can increase feelings of burden, impact caregivers' wellbeing, and increase mental health stigma. Psychosocial interventions are increasingly used for psychosis in South Asia and could reduce relapse and symptoms, reduce caregiver burden, conserve cost and resources. The aim of this review was to appraise the effectiveness and implementation readiness of psychosocial interventions for people with psychosis in South Asia.

METHOD

A systematic search was conducted on MEDLINE, PsycINFO, Global Health, and Web of Science. The review was prospectively registered on PROSPERO (CRD42022329254). Studies were rated on two scales assessing quality and implementation readiness.

RESULTS

Twenty-six papers were included, nine intervention-types including community-based interventions/assertive outreach; CaCBTp; FAP; psychoeducation; cognitive retraining/rehabilitation; social cognition/skills; family/ caregiver intervention; telehealth intervention; yoga-based intervention in six South Asian countries. Findings suggest a multicomponent community-based intervention (MCBI) was the most implementation ready due to its standardisation, good clinical outcomes for patients and caregivers, and training and cost evaluations.

CONCLUSION

Of the included studies, MCBI and community-based outreach interventions utilising lay health workers appear to be the most implementation ready and are suggested to best address the treatment gap in South Asia.

Exploring biomedical and traditional care pathways for people with psychosis in Karachi, Pakistan

Background

Psychosis is known to have an adverse impact on an individual's quality of life, social and occupational functioning. A lack of treatment options for psychotic disorders such as schizophrenia contributes to adverse outcomes for individuals. A significant proportion of people with psychosis consult both formal and traditional routes of care. This warrants a need to explore perceptions around treatment options provided by diverse care providers, as the identification of avenues for support can improve psychiatric, alternative treatment and social outcomes.

Methods

Focus groups discussions (FGDs) and in-depth interviews (IDIs) were used. Interactive Research and Development (IRD) research staff conducted 20 IDIs and 2 FGDs to obtain information about the perspectives, treatment pathways and experiences of individuals with psychosis, their caregivers, and service providers. Questions for clinician care providers and faith healers revolved around perceptions of psychosis, service users' background, subject knowledge and treatment, feedback and referral mechanisms, and promotion of services. A thematic analysis was used to analyze the interviews and coding was conducted on NVivo.

Results

The results were categorized into five themes: perception of psychosis, experience of seeking/receiving care, assessment and diagnosis methods, promotion of services, and living with psychosis. Across service providers and patients, there was a wide variety of causes attributed to psychosis, and an overall lack of awareness regarding severe mental health conditions from both formal and informal care-providers. Biomedical treatment received mixed reviews, while some reported it as beneficial, the limited number of institutes and clinicians to cater for patients, stigma within society and care providers, the burden of caregiving, and misinformation from faith healers were all significant barriers to treatment.

Conclusion

The results highlight the use of traditional healing practices for psychosis in Pakistan, which, coupled with inadequate referral mechanisms, present an opportunity to bridge the treatment gap between clinical and traditional healing practices through integration of treatment within community structures and systems. Better awareness of psychosis and its treatment methods, alongside interventions that reduce stigma could help facilitate help-seeking behavior and reduce the burden of caregiving.

Assessing the effectiveness and cost-effectiveness of a solution-focused resource-orientated approach (DIALOG+) to improving the quality of life for people with psychosis in India and Pakistan-a cluster RCT

BACKGROUND

Severe mental illness (SMI) presents a major challenge worldwide, affecting approximately 5-8% of the world's population. It causes significant distress to affected people, families and wider communities, generating high costs through loss of productivity and ongoing healthcare use. Over 75% of patients with psychosis receive inadequate care and experience a negative financial impact and reduced quality of life (QoL). It is therefore a priority to reduce the treatment gap by providing low-cost, effective interventions for people with psychosis. Our research project, PIECEs, is designed to explore, adapt and test a low-cost, approach (DIALOG+) that makes use of existing resources to improve community-based care for patients with psychosis. The research will be conducted in two urban sites: Karachi, Pakistan and Chennai, India. DIALOG+ is a novel, technology-assisted and resource-oriented intervention, based on QoL research, concepts of patient-centred communication, IT developments and solution-focused therapy. However, the approach has not been rigorously tested within India and Pakistan. Our randomised controlled trial (RCT) aims to test the effectiveness and cost-effectiveness of DIALOG+ in improving the QoL and clinical outcomes for individuals with long-term psychosis being treated in the community in India and Pakistan.

METHODS

To assess the acceptability, feasibility, and cost effectiveness of DIALOG+, we will conduct a cluster RCT with 210 patients and 14 clinicians in each country. The intervention will be used during a routine interaction between a clinician and a patient. It consists of a patient-centred assessment (the DIALOG scale) whereby the clinician invites the patient to rate their satisfaction with different life domains and treatment aspects, which forms the active control group. The intervention group will follow this up with a four-step solution-focused approach to identify the patient's resources and develop solutions to deal with the patient's concerns (DIALOG+).

DISCUSSION

If shown to be effective DIALOG+ has the potential to improve community-based care and the QoL for millions of people within India and Pakistan who experience psychosis.

TRIAL REGISTRATION

The trial was registered prospectively on the ISRCTN Registry: ISRCTN13022816 on 9 February 2022.

Implementing psychosocial interventions within low and middle-income countries to improve community-based care for people with psychosis-A situation analysis

BACKGROUND

Globally, a treatment gap exists for individuals with severe mental illness, with 75% of people with psychosis failing to receive appropriate care. This is most pronounced in low and middle-income countries, where there are neither the financial nor human resources to provide high-quality community-based care. Low-cost, evidence-based interventions are urgently needed to address this treatment gap.

AIM

To conduct a situation analysis to (i) describe the provision of psychosocial interventions within the context of existing care in two LMICs-India and Pakistan, and (ii) understand the barriers and facilitators of delivering a new psychosocial intervention.

METHOD

A situation analysis including a quantitative survey and individual interviews with clinicians, patients and caregivers was conducted. Quantitative survey data was collected from staff members at 11 sites (private and government run hospitals) to assess organizational readiness to implement a new psychosocial intervention. To obtain in-depth information, 24 stakeholders including clinicians and service managers were interviewed about the typical care they provide and/or receive, and their experience of either accessing or delivering psychosocial interventions. This was triangulated by six interviews with carer and patient representatives.

RESULTS AND DISCUSSION

The results highlight the positive views toward psychosocial interventions within routine care and the enthusiasm for multidisciplinary working. However, barriers to implementation such as clinician time, individual attitudes toward psychosocial interventions and organizational concerns including the lack of space within the facility were highlighted. Such barriers need to be taken into consideration when designing how best to implement and sustain new psychosocial interventions for the community treatment of psychosis within LMICs.

Lay-delivered talk therapies for adults affected by humanitarian crises in low- and middle-income countries

BACKGROUND

Published by the World Health Organization (WHO) and United Nations High Commissioner for Refugees (UNHCR) in 2015, the mental health Gap Action Programme Humanitarian Intervention Guide (mhGAP-HIG) recommends brief versions of structured psychological interventions for people experiencing symptoms of common mental disorders (CMDs). mhGAP-HIG acknowledges a growing body of evidence suggesting these interventions can be delivered by lay workers to people affected by humanitarian crises in low- and middle-income countries (LMICs). However, there has not yet been a systematic review and synthesis of this evidence. This paper reports the results of a systematic review of qualitative, quantitative, and mixed-methods studies assessing the implementation and/or effectiveness of talk therapies for CMDs when provided by lay workers in LMICs to adults who have survived or are currently living in humanitarian situations.

METHODS

Seven electronic databases were searched: MEDLINE, Embase, PsycINFO, PsycEXTRA, Global Health, Cochrane Library, and ClinicalTrials.gov . We also hand-searched the contents pages of three academic journals, reference lists of 30 systematic reviews, and online resource directories of two mental health networks. A preliminary list of included studies was circulated to topical experts for review, and all included studies were backward and forward searched. All titles, abstracts, and full-texts were independently double-screened. Quality appraisal and data extraction were carried out by a single reviewer and checked by a second reviewer, using standardised tools. Any disagreements were discussed and referred to a third reviewer as needed.

RESULTS

We identified 23 unique studies and carried out a narrative synthesis of patient and implementation outcome data. Every evaluation of the effectiveness of lay-delivered talk therapies for adults affected by humanitarian crises in LMICs showed some treatment effect for at least one CMD, and often multiple CMDs. Implementation research generally found these interventions to be acceptable, appropriate and feasible to implement, with good fidelity to manualised therapies.

CONCLUSION

Although results are promising, particularly for individually-delivered talk therapies based on cognitive behavioural therapy techniques, there is a high degree of heterogeneity in this literature. We make several recommendations on how to improve the quality and generalisability of research on this topic, to facilitate further evidence synthesis.

Barriers and drivers to stakeholder engagement in global mental health projects

Background

Engagement with diverse stakeholders, including policy makers, care providers and service users and communities, is essential for successful implementation of global mental health interventions. Despite being a fundamental factor in the implementation process, evidence about challenges and drivers to stakeholder engagement is limited in the global mental health literature.

Methods

We conducted semi-structured qualitative interviews with 29 recipients of Grand Challenges Canada Global Mental Health funding to assess barriers and drivers to global mental health implementation across a portfolio of projects. We used framework analysis to identify key themes related to implementation barriers and drivers. This paper reports on barriers and drivers to stakeholder engagement, with results related to capacity development and service delivery reported elsewhere in this journal.

Results

Barriers and drivers to stakeholder engagement were identified across four themes: (1) Contextual Considerations, (2) Resources, (3) Participation, Uptake and Empowerment, and (4) Stigma. While complex contextual challenges create barriers, mechanisms such as formative research can facilitate a deeper contextual understanding that supports effective implementation planning. Limited financial and human resources and competing priorities can lead to substantial challenges. Investing in and leveraging existing local resources and expertise can help to mitigate these barriers. The challenge of achieving active participation from stakeholders and diverging expectations about the nature of participation were identified as barriers, while providing opportunities for meaningful participation and empowerment acted as drivers. Stigma at the institutional, community and individual level was also identified as a substantial barrier to engagement.

Conclusion

The findings of this study are relevant to implementers in global mental health. They also have implications for global mental health funding agencies and policy organizations, who can support improved stakeholder engagement by investing in high-quality formative research, supporting capacity building for policy engagement, investing in longer-term funding schemes to support sustainable partnerships and scale-up, thus fostering successful engagement and supporting effective implementation of global mental health innovations.

Lessons from a theory of change-driven evaluation of a global mental health funding portfolio

BACKGROUND

Given the underinvestment in global mental health to-date, it is important to consider how best to maximize the impact of existing investments. Theory of Change (ToC) is increasingly attracting the interest of funders seeking to evaluate their own impact. This is one of four papers investigating Grand Challenges Canada's (GCC's) first global mental health research funding portfolio (2012-2016) using a ToC-driven approach.

METHODS

A portfolio-level ToC map was developed through a collaborative process involving GCC grantees and other key stakeholders. Proposed ToC indicators were harmonised with GCC's pre-existing Results-based Management and Accountability Framework to produce a "Core Metrics Framework" of 23 indicators linked to 17 outcomes of the ToC map. For each indicator relevant to their project, the grantee was asked to set a target prior to the start of implementation, then report results at six-month intervals. We used the latest available dataset from all 56 projects in GCC's global mental health funding portfolio to produce a descriptive analysis of projects' characteristics and outcomes related to delivery.

RESULTS

12,999 people were trained to provide services, the majority of whom were lay or other non-specialist health workers. Most projects exceeded their training targets for capacity-building, except for those training lay health workers. Of the 321,933 people screened by GCC-funded projects, 162,915 received treatment. Most projects focused on more than one disorder and exceeded all their targets for screening, diagnosis and treatment. Fewer people than intended were screened for common mental disorders and epilepsy (60% and 54%, respectively), but many more were diagnosed and treated than originally proposed (148% and 174%, respectively). In contrast, the three projects that focused on perinatal depression exceeded screening and diagnosis targets, but only treated 43% of their intended target.

CONCLUSIONS

Under- or over-achievement of targets may reflect operational challenges such as high staff turnover, or challenges in setting appropriate targets, for example due to insufficient epidemiological evidence. Differences in delivery outcomes when disaggregated by disorder suggest that these challenges are not universal. We caution implementers, funders and evaluators from taking a one-size-fits all approach and make several recommendations for how to facilitate more in-depth, multi-method evaluation of impact using portfolio-level ToC.

Barriers and drivers to service delivery in global mental health projects

BACKGROUND

Research in global mental health (GMH) has previously documented how contextual factors like political instability, poverty and poorly-funded health infrastructure continue to compromise effective and equitable mental health service delivery. There is a need to develop more feasible and evidence-based solutions through implementation research. This paper, one in a series pertaining to implementation in GMH projects worldwide, focuses on implementation factors influencing mental health service delivery.

METHODS

This is a qualitative study carried out as part of a Theory of Change-driven evaluation of Grand Challenges Canada's (GCC's) Global Mental Health portfolio. Purposive sampling was used to recruit twenty-nine GCC grantees for interviews. A semi-structured interview schedule was used to guide the interviews which were recorded and subsequently transcribed. Transcripts were double-coded and analyzed in NVivo 11 using framework analysis. This paper reports results related to detection and treatment of mental illness, mental health promotion and prevention of mental illness.

RESULTS

Key barriers included: lack of appropriate human resources and expertise for service delivery; lack of culturally appropriate screening tools and interventions; and difficulties integrating services with the existing mental health system. Formative research was a key driver facilitating the cultural adaptation of mental health detection, treatment, promotion and preventative approaches. Recruiting local providers and utilizing mHealth for improving screening, monitoring and data management were also found to be successful approaches in reducing workforce burden, improving sustainability, mental health literacy, participant engagement and uptake.

CONCLUSIONS

The study identifies a number of key barriers to and drivers of successful service delivery from the perspective of grantees implementing GMH projects. Findings highlight several opportunities to mitigate common challenges, providing recommendations for strengthening systems- and project-level approaches for delivering mental health services. Further, more inclusive research is required to inform guidance around service delivery for successful implementation, better utilization of funding and improving mental health outcomes among vulnerable populations in low-resource settings.

Barriers and drivers to capacity-building in global mental health projects

BACKGROUND

The global shortage of mental health workers is a significant barrier to the implementation and scale-up of mental health services. Partially as a result of this shortage, approximately 85% of people with mental, neurological and substance-use disorders in low- and middle-income countries do not receive care. Consequently, developing and implementing scalable solutions for mental health capacity-building has been identified as a priority in global mental health. There remains limited evidence to inform best practices for capacity building in global mental health. As one in a series of four papers on factors affecting the implementation of mental health projects in low- and middle-income countries, this paper reflects on the experiences of global mental health grantees funded by Grand Challenges Canada, focusing on the barriers to and drivers of capacity-building.

METHODS

Between June 2014 and May 2017, current or former Grand Challenges Canada Global Mental Health grantees were recruited using purposive sampling. N = 29 grantees participated in semi-structured qualitative interviews, representing projects in Central America and the Caribbean (n = 4), South America (n = 1), West Africa (n = 4), East Africa (n = 6), South Asia (n = 11) and Southeast Asia (n = 3). Based on the results of a quantitative analysis of project outcomes using a portfolio-level Theory of Change framework, six key themes were identified as important to implementation success. As part of a larger multi-method study, this paper utilized a framework analysis to explore the themes related to capacity-building.

RESULTS

Study participants described barriers and facilitators to capacity building within three broad themes: (1) training, (2) supervision, and (3) quality assurance. Running throughout these thematic areas were the crosscutting themes of contextual understanding, human resources, and sustainability. Additionally, participants described approaches and mechanisms for successful capacity building.

CONCLUSIONS

This study demonstrates the importance of capacity building to global mental health research and implementation, its relationship to stakeholder engagement and service delivery, and the implications for funders, implementers, and researchers alike. Investment in formative research, contextual understanding, stakeholder engagement, policy influence, and integration into existing systems of education and service delivery is crucial for the success of capacity building efforts.

Barriers and facilitators of mental health programmes in primary care in low-income and middle-income countries

Integration of services into primary health care for people with common mental disorders is considered a key strategy to improve access to mental health care in low-income and middle-income countries, yet services at the primary care level are largely unavailable. We did a systematic review to understand the barriers and facilitators in the implementation of mental health programmes. We searched five databases and included studies published between Jan 1, 1990, and Sept 1, 2017, that used qualitative methods to assess the implementation of programmes for adults with common mental disorders at primary health-care settings in low-income and middle-income countries. The Critical Appraisal Skills Programme Qualitative Checklist was used to assess the quality of eligible papers. We used the so-called best fit framework approach to synthesise findings according to the Consolidated Framework for Implementation Research. We identified 24 papers for inclusion. These papers described the implementation of nine programmes in 11 countries. Key factors included: the extent to which an organisation is ready for implementation; the attributes, knowledge, and beliefs of providers; complex service user needs; adaptability and perceived advantage of interventions; and the processes of planning and evaluating the implementation. Evidence on implementation of mental health programmes in low-income and middle-income countries is scarce. Synthesising results according to the Consolidated Framework for Implementation Research helped to identify key areas for future action, including investment in primary health-care strengthening, capacity building for health providers, and increased support to address the social needs of service users.
