Grand Challenges in Global Mental Health

Grand Challenges in Global Mental Health

OVERVIEW

The Grand Challenges in Global Mental Health Initiative was led by the National Institute of Mental Health (NIMH) and the Global Alliance for Chronic Disease in partnership with the Wellcome Trust, the McLaughlin-Rotman Centre for Global Health, and the London School of Hygiene and Tropical Medicine.

The Grand Challenges Initiative provided a critical opportunity to bring mental, neurological and substance use (MNS) disorders to the forefront of global attention and scientific inquiry. The aim of the initiative was to identify research priorities that, if addressed within the next decade, could lead to substantial improvements in the lives of people living with neuropsychiatric illnesses.  A grand challenge was defined as a specific barrier that, if removed, would help to improve the lives of those affected by mental, neurological, or substance use disorders.

For the purposes of the Grand Challenges Initiative, the broad category called ‘mental health’ referred to factors (including disorders) influencing the health of the mind, brain, and nervous system. These conditions account for approximately 10% of the global burden of disease, as indicated by disability-adjusted life years (DALYs) reported by the World Health Organization [1] and the Global Burden of Disease 2010 study. [2] As a group, they are the leading causes of disability worldwide.[3] MNS disorders within the Initiative’s remit included depression, anxiety disorders, schizophrenia, bipolar disorder, alcohol and drug use disorders, mental disorders of childhood, migraines, dementias, epilepsy, etc. Conditions with a vascular or infectious etiology were excluded, as these were addressed in previous Grand Challenges initiatives.

The term ‘global’ encompasses mental health in any country of the world. A core focus in global mental health is to both reduce the overall burden of illness and to reduce -- and ultimately eliminate -- health inequities within and between countries. The term ‘global’ also refers to global influences on mental health -- for example, cross-national factors such as conflict, climate change or macroeconomic policies. The responsibility for improving global mental health transcends national borders, class, race, gender, ethnicity and culture; promoting global mental health requires collective action based on global partnerships.

BACKGROUND AND RATIONALE

Recognizing the importance of collective action for overcoming scientific hurdles, the global health community embraced the use of challenge initiatives for improving the lives of its global constituency. In 2003, the Grand Challenges in Global Health project promoted the discovery and development of new tools to fight infectious diseases that cause millions of deaths each year in developing countries. [1] In 2007, the Grand Challenges in Chronic Non-Communicable Diseases study addressed non-communicable disorders (excluding mental health) which have reached epidemic proportions in both the developed and developing worlds.[2] Both of these initiatives led to the commitment of significant new programs of funding from a community of private and federal organizations around the world.

In 2010, the Grand Challenges in Global Mental Health initiative was launched to focus our collective efforts on global mental health.

The 2010 Global Burden of Disease Study identified MNS/neuropsychiatric disorders as substantial sources of disease burden.[3],[4] As a group, mental and behavioral disorders are the leading causes of disability worldwide. In combination with neurological disorders, these disorders account for around 10 percent of the total global burden of disease.

Disease burden is not the only factor that renders neuropsychiatric disorders a high-priority topic. Across the world, the treatment gaps for these conditions are large; thus, many in need of care do not receive adequate or effective interventions. People living with neuropsychiatric disorders often face systematic discrimination in diverse domains of their lives. Despite the suffering and disability that neuropsychiatric disorders can cause, relatively few resources are allocated worldwide to fund the necessary research to effectively prevent and treat neuropsychiatric disorders.

In order to assist in targeting the limited resources for action, several priority-setting exercises have resulted in proposed research strategies in global mental health. A series of papers in The Lancet in 2007 reference identified gaps in the evidence base for depressive disorders, alcohol and substance-use disorders, child and adolescent mental disorders, and psychotic disorders, with a focus on closing the 

treatment gaps in developing countries. This group suggested a prioritization of research on implementation science, for example health policy and systems research, research on affordable delivery of cost-effective interventions, and epidemiological research on childhood disorders and substance use disorders.[1] In addition, WHO and the Global Forum for Health Research assessed priorities for research in low- and middle-income countries reporting that epidemiology, health systems, and social science research were top priorities. [2],[3]

The Grand Challenges in Global Mental Health Initiative built on these and other exercises to identify impediments to reducing the suffering associated with neuropsychiatric disorders. Identifying these challenges will help us determine the major scientific advances that are needed to make a significant impact on the lives of people living with neuropsychiatric disorders worldwide. The Initiative was unique in that its scope was global in perspective; it addressed a wide range of disorders that affect the nervous system; the consultation process involved a wide community of stakeholders; and, this initiative was explicitly linked to the support of a community of funders.

METHODOLOGY

The methodology was an adaptation of the Delphi method used for the Grand Challenges in Chronic Non-communicable Diseases study. A Delphi Panel consisting of approximately 400 stakeholders was surveyed three times. Panel members were selected to provide a representation of the diverse clinical, policy, advocacy, user and research communities whose interests are covered within the Initiative’s scope of global mental health.

Specifically, the Initiative's adapted Delphi method consisted of the following major steps:

  1. The Scientific Advisory Board established the scope and question for the Initiative.
  2. The Scientific Advisory Board guided the selection of a broad and representative Delphi Panel.
  3. Round 1: Each member of the Delphi Panel submitted his or her suggestions in response to the Grand Challenges question.
  4. The NIMH Working Group qualitatively synthesized the Round 1 responses.
  5. Round 2: Each member of the Delphi Panel selected his or her top 40 challenges from the longer list of Grand Challenges identified in and synthesized following Round 1.
  6. The NIMH Working Group compiled a consolidated list of the top 40 Grand Challenges from Delphi Panelists’ selections.
  7. Round 3: Each member of the Delphi Panel rated the consolidated list of 40 Grand Challenges on four dimensions (Feasibility; Potential for disease burden reduction; Impact on equity in population; and Immediacy of impact).
  8. The NIMH Working Group analyzed the results and presented them in summary form to the Scientific Advisory Board for interpretation.
  9. The leadership teams published a manuscript in July 2011 describing the initiative and presenting the top 25 challenges.

RESULTS

The findings from the Grand Challenges in Global Mental Health initiative were published as a comment in the July 7, 2011 issue of Nature (PMC3173804 ).

Of the 594 individuals nominated to the Delphi panel, 422 agreed to participate.  They worked in 60 countries around the world, with the largest percentage (24%) working in Asia, followed by Africa and North America (both 20%), Central and South America (18%), Europe (16%), and Australia, and New Zealand (2%). 

The three rounds of the prioritization exercise yielded six grand challenge goals (Table 1) and 40 grand challenges (Table 2).  These identified priorities encompass a spectrum of research activities, ranging from basic, discovery science to implementation and policy research.  Four themes recurred throughout the data: 1) use a life-course approach to study MNS disorders; 2) use system-wide approaches to address suffering; 3) use evidence-based interventions for MNS disorders; and, 4) understand environmental influences on risk and resilience for MNS disorders.

Table 1. Grand Challenge Goals
Goal A Identify root causes, risk and protective factors
Goal B Advance prevention and implementation of early interventions
Goal C Improve treatments and expand access to care
Goal D Raise awareness of the global burden
Goal E Build human resource capacity
Goal F Transform health system and policy responses
