In the 19th century, psychiatric institutions were the focus of thousands of articles in the leading English-language medical and psychiatric journals. This area of concern remained important through the first half of the 20th century, with some decline in the number of published articles in the second half of the 20th century as de-institutionalisation gathered pace. The number of articles about this topic has declined sharply in the past 25 years, and psychiatric institutions are not the focus of any of the Grand Challenges in Global Mental Health even though psychiatric institutions of all kinds are widely acknowledged to be the among the main sites of human rights abuses. In this commentary we present examples of impressive transformations of institutions in Sri Lanka and Vietnam, and suggest that the field of global mental health should devote more of its efforts to improving the lives of persons with mental disorders who have been incarcerated in a variety of settings, often under the care of mental health specialists.

Guideline methods to develop recommendations dedicate most effort around organising discovery and corroboration knowledge following the evidence-based medicine (EBM) framework. Guidelines typically use a single dimension of information, and generally discard contextual evidence and formal expert knowledge and consumer's experiences in the process. In recognition of the limitations of guidelines in complex cases, complex interventions and systems research, there has been significant effort to develop new tools, guides, resources and structures to use alongside EBM methods of guideline development. In addition to these advances, a new framework based on the philosophy of science is required. Guidelines should be defined as implementation decision support tools for improving the decision-making process in real-world practice and not only as a procedure to optimise the knowledge base of scientific discovery and corroboration. A shift from the model of the EBM pyramid of corroboration of evidence to the use of broader multi-domain perspective graphically depicted as ‘Greek temple’ could be considered. This model takes into account the different stages of scientific knowledge (discovery, corroboration and implementation), the sources of knowledge relevant to guideline development (experimental, observational, contextual, expert-based and experiential); their underlying inference mechanisms (deduction, induction, abduction, means-end inferences) and a more precise definition of evidence and related terms. The applicability of this broader approach is presented for the development of the Canadian Consensus Guidelines for the Primary Care of People with Developmental Disabilities.

Given the multitude of risk factors for depression in modern society and given the negative consequences of depressive problems for successful ageing, investigating resilience in relation to depression may help identifying entry points for reducing the burden of morbidity. Research on resilience begins with the realisation that individuals may demonstrate good physical or psychological functioning despite being exposed to risk experiences that can have serious negative impact on functioning. Interest in investigating resilience within ageing research has been increasing. Among the approaches toward investigating resilience are so-called a priori approaches, where criteria for inferring resilience are established a priori. In this editorial, we highlight some of the advantages of taking a priori approaches to the study of resilience and we touch on the implications for a priori approaches for the topic of resilience and depression. We argue that depression should take a prominent role in resilience research, because depression is strongly associated with opportunities for successful ageing.

Mental, neurological and substance use disorders (MNS) are a leading cause of disability in Africa. In response to the large treatment gap for MNS, a growing body of evidence-based treatments (EBTs) is emerging from Africa; however, there is a dearth of knowledge on how to scale up EBT. The Friendship Bench intervention is a brief psychological treatment delivered through the primary health care system in Zimbabwe by trained lay health workers. It has contributed significantly towards narrowing the treatment gap for common mental disorders in Zimbabwe where it has been scaled up to over 70 primary health care facilities. A three-pronged approach consisting of community engagement, use of EBTs and a government endorsed scale-up plan is described as part of the key strategy leading to the scale up of the Friendship Bench.

The persistence of attention-deficit hyperactivity disorder (ADHD) from adolescence to adulthood is not matched by continuity of care in this transition period. Many adolescents with ADHD have poor medication adherence or even stop medication treatment, and use of behavioural interventions is also suboptimal. The present commentary focuses on treatment strategies that might improve effects of ADHD medication treatment by improving adherence in adolescents with ADHD and/or optimise behavioural interventions for ADHD in adolescence. Most treatment strategies in adolescents with ADHD are merely copied from treatments offered to children. Instead however treatment should be focused on what makes adolescents special and vulnerable, such as poor insight into own functioning and poor decision making. Techniques that offer promise for adolescents are motivational interviewing, use of ecological momentary assessments and interventions, mindfulness-based training and serious games. Systematic studies into the effects of these techniques alone and in combination with medication are lacking.

Comprehensive psychiatric rehabilitation programs in Latin America have been designed across several countries in the region without yet achieving full implementation. Facing an increasing burden of disease due to mental disorders, including alcohol and substance use disorders, the region has responded unevenly to the challenge. Moreover, low priority for mental health in national policies and insufficient funding for mental health services are common barriers for the much-needed mental health services reforms. Reestablishing a primary care community-based model of care has been a shared aspiration for most countries during the last two decades. Comprehensive models of psychiatric rehabilitation developed predominantly in high-income countries need to be culturally adapted to local contexts, while strengthening health systems research will provide evidence on the efficiency of locally designed interventions and on the critical milestones to succeed in the scaling up strategies. Increasing participation of patients and their families in the mental health delivery system is another key factor in order to ensure comprehensive patient-centred psychosocial rehabilitation programs in Latin America.

To describe the core elements of modern psychiatric rehabilitation. Based on selected examples we describe the discussion about values in mental health care with focus on Europe. We present outcome data from studies, which have tried to implement care structures based on this value discussion. In the second half of the 20th century, mental health care in all European and other high-income countries changed conceptually and structurally. Deinstitutionalisation reduced the number of psychiatric beds and transferred priority to outpatient care and community-based services, but community mental health programs developed differently across and within these countries. High-income countries in Europe continued to invest in costly traditional services that were neither evidence-based nor person-centered by emphasising inpatient services, sheltered group homes and sheltered workshops. We argue that evidence-based, person-centred, recovery-oriented psychiatric rehabilitation offers a parsimonious solution to developing a consensus plan for community-based care in Europe. The challenges to scaling up effective psychiatric rehabilitation services in high-income countries are not primarily a lack of resources, but rather a lack of political will and inefficient use and dysfunctional allocation of resources.

The extension of life does not appear to be slowing, representing a great achievement for mankind as well as a challenge for ageing populations. As we move towards an increasingly older population we will need to find novel ways for individuals to make the best of the challenges they face, as the likelihood of encountering some form of adversity increases with age. Resilience theories share a common idea that individuals who manage to navigate adversity and maintain high levels of functioning demonstrate resilience. Traditional models of healthy ageing suggest that having a high level of functioning across a number of domains is a requirement. The addition of adversity to the healthy ageing model via resilience makes this concept much more accessible and more amenable to the ageing population. Through asset-based approaches, such as the invoking of individual, social and environmental resources, it is hoped that greater resilience can be fostered at a population level. Interventions aimed at fostering greater resilience may take many forms; however, there is great potential to increase social and environmental resources through public policy interventions. The wellbeing of the individual must be the focus of these efforts; quality of life is an integral component to the enjoyment of additional years and should not be overlooked. Therefore, it will become increasingly important to use resilience as a public health concept and to intervene through policy to foster greater resilience by increasing resources available to older people. Fostering wellbeing in the face of increasing adversity has significant implications for ageing individuals and society as a whole.

The explicit inclusion of mental health within the Sustainable Development Goals is a welcome development, borne out of powerful advocacy using public health, economic and human rights arguments. As funding comes on line for scale-up of evidence-based mental health care by task-sharing with primary care, it is time to take stock about care for people affected by severe mental illness (SMI). The existing evidence base for task shared care for SMI provides an imperative to get started, but is skewed towards relatively more affluent and urban populations in middle-income countries where specialist mental health professionals provide most of the care. Randomised, controlled trials and rigorous implementation research on task shared service models are underway which will go some way to improving understanding of the quality, safety, effectiveness and acceptability of more widely generalisable care for people with SMI. A sub-group of people with SMI have more complex and long-term needs for care, with a high risk of homelessness, imprisonment and human rights violations as family and social supports become overwhelmed. Case studies from non-governmental organisations provide examples of holistic approaches to rehabilitation, recovery and empowerment of people with SMI, but rigorous comparative studies are needed to identify the most efficient, effective and scalable approaches to care. Health system constraints are emerging as the over-riding barriers to successful task-sharing, highlighting a need to develop and evaluate chronic care models for people with SMI that succeed in reducing premature mortality, improving wellbeing and achieving better social outcomes. Addressing these evidence gaps is essential if task-sharing mental health care is going to deliver on its promise of promoting recovery for the full range of people affected by SMI.

There is considerable variation in practice, both between and with different countries in the management of attention deficit hyperactivity disorder (ADHD). Whilst there is no one optimal model of service organisation there are general principles of care that can be introduced to reduce this variability. There are frequent debates and discussions about which professional group is best placed to manage ADHD at different points in the life cycle. Who delivers care is however less important than ensuring that training schemes provide adequate exposure, training and experience to both the core and non-core skills required to provide a comprehensive package of care. Most evidence-based guidelines recommend a multi-modal, multi-professional and multi-agency approach. Many also promote the use of both stepped care and shared care approaches for the management of ADHD. As most of those with ADHD continue to have ADHD-related problems into adulthood, it is important to consider how best to transition care into adulthood and think about who should deliver care to adults with ADHD. Young people with ADHD should generally be transferred to adult mental health services if they continue to have significant symptoms of ADHD or other coexisting conditions that require treatment. Unfortunately services for adults with ADHD remain relatively scarce across much of the world and some adult psychiatrists remain unsure of the diagnosis and uncertain about the appropriate use of ADHD medications in adults, but there is a strong case for increased services for adults. ADHD is on the one hand easy to treat; it is much more difficult to treat well. Although optimised care for ADHD requires routine measurement of outcomes, this often does not happen in routine clinical practice. Focusing on optimising symptoms and minimising adverse effects can significantly improve both short- and long-term outcomes.

Mental hospitals in India, as elsewhere in the world, have played an important role in the care of persons with mental illness. Since their inception, they have both been decried for gross violations of human rights and dignity as well as lauded as places of refuge and care for persons turned away by the communities. In a country where community interventions for mental health care are still fragmentary, the mental hospital still continues to be a relevant and legitimate locus of care along with other limited resources available for the care of persons with mental illness outside of the family. In India, positive changes in the infrastructure and resourcing of mental hospitals, reductions in involuntary admissions and improvements in facilities have largely occurred through judicial interventions. Recent pilot interventions for rehabilitation of long-stay patients point towards the need to develop rehabilitation and community facilities for persons with severe mental illness.

Politics and policy: It is important to understand why, in the translational continuum from pilot research and randomised controlled efficacy trials to roll-out programmes and routine effectiveness studies, some service innovations are taken up by health service purchasers and providers, while others are not. Why do some innovative interventions or models of care get to the stage of implementation, while others fail to be funded?
