In Britain, there has been a major increase in economic inactivity due to mental ill-health. This has huge fiscal costs. Clearly, such people need treatment for their condition. But they also need help with finding work and keeping it.
This chapter examines the well-tested system of Individual Placement and Support (IPS). Most trials show quite large increases in the proportion of people in work. Using reasonable assumptions, we find that, for people with mild or moderate mental health problems, IPS pays for itself within five years. For people with severe mental health problems, the BCR is 1.7. This is quite low, but one should note that the beneficiaries of the policy are among the most unhappy members of the community.

Mental illness is common: at least 20 per cent of adults suffer from it at any one time. Depression and anxiety disorders are the most common conditions and they reduce life satisfaction by 0.7 points (out of 10). In the UK the health watchdog NICE recommends that all patients are offered psychological therapy. Until 2008 almost none were, but since then, NHS Talking Therapies (NHSTT) has treated some eight million patients of whom half have recovered during therapy. Many have gone back to work and the service brings more money into the Exchequer in taxes paid (and benefits not paid) to more than cover the original cost of the therapy. This happens within two years of the end of treatment. There are also important reductions in the use of NHS physical healthcare services.
But the service does not cover people suffering from addiction, personality disorder or other severe mental illness. This chapter evaluates provision of psychological therapy on a large scale to those people. It concludes that this provision too would pay for itself within two years.
In this introductory chapter we provide an overview of the whole book and discuss the wider context of legal practice and lawyers’ ethics. We then explore insights from general morality as an underlying framework for the four approaches to lawyers’ ethics discussed in Chapter 2. This framework compensates, to some extent, for the lack of an explicit statement of values in our current rules of professional conduct. We then consider the ethical decision-making process, including the skills we need to put our ethics into action. In each chapter, we make extensive use of case studies to illustrate our points and to provide an opportunity for students (and other readers) to develop their own values-based judgements and apply the law of lawyering in respect of the topics covered.
In Chapter 1, human well-being is defined and compared globally as inherently relational and creative, based on current research, indicating that the impact of technology is causing societal and individual stress, particularly due to social isolation.
Depression and post-traumatic stress disorder (PTSD) are highly prevalent and frequently co-occur in conflict-affected populations, yet the complex relationships among their symptoms remain poorly understood. This study applied psychological network analysis and Bayesian network modelling to examine symptom associations and exploratory directional dependencies among participants living in Cox’s Bazar and neighbouring Bandarban, Bangladesh.
Methods
Baseline data were obtained from 9,397 participants, including forcibly displaced Rohingya refugees and host-community members. Depression symptoms (Patient Health Questionnaire-9) and PTSD symptoms (Harvard Trauma Questionnaire-16) were analysed using regularized partial correlation networks and directed acyclic graphs. Symptom centrality, bridge centrality, predictability and network stability were assessed, alongside sensitivity analyses by settlement status and sex.
Results
Distinct yet interconnected clusters of depression and PTSD symptoms emerged. Guilt, anhedonia, recurrent traumatic thoughts, emotional detachment, hopelessness about the future and rumination emerged as the most central symptoms. Bridge-strength analyses identified guilt and physical health problems as the most prominent bridge symptoms linking depression and PTSD symptom communities. Bayesian network analysis identified several highly stable exploratory directional dependencies involving anhedonia, guilt, rumination, recurrent traumatic thoughts and emotional detachment. The network demonstrated excellent stability (correlation stability = 0.75), while symptom-level classification accuracy ranged from 0.542 to 0.791. Sensitivity analyses indicated that network structure differed across settlement settings, whereas no significant difference in overall network structure was detected between sexes.
Conclusions
These findings provide a nuanced understanding of symptom interrelationships between depression and PTSD in a major humanitarian setting. Symptoms such as guilt, rumination, recurrent traumatic thoughts and physical health problems warrant further interventions as potential intervention targets, potentially informing more focused and culturally sensitive mental health strategies for conflict-affected populations.
Animal welfare investigations on farms often reveal livestock neglect that may be associated with psychological distress, reduced capacity, or other challenges affecting farmer well-being. Most animal welfare assessment tools focus on animal-based indicators, and do not typically incorporate observable human or property indicators. This study explored animal protection officers’ observations and experiences during farm animal welfare investigations to identify observable human, property, and animal indicators associated with these investigations and to develop a One Welfare-informed assessment tool to support field-based assessments. Although investigations frequently involve animals already in distress, these indicators may reflect underlying strain that contributes to worsening welfare issues if unaddressed. Focusing on farming operations in Alberta, Canada, data were collected through focus groups and interviews with animal protection officers (n = 18) and analysed using inductive thematic analysis. Six themes were identified: property and grounds disrepair; compromised human living conditions; farmer distress; animal neglect; unusual livestock management; and animal and material overaccumulation. These themes reflected interconnected human, property, and animal indicators. Findings were translated into a 60-item assessment tool of farmer behaviour, property conditions, and animal care indicators that may support early identification of risk and guide tailored interventions when education or enforcement alone are insufficient. The tool includes Levels of Concern with recommended follow-up actions and was pilot tested by two officers. Integrating human and property indicators into animal welfare assessments would offer a practical approach to identifying concerns related to farmer well-being and animal welfare.
Prolonged war-related adversity places Ukrainian university students at heightened risk of psychological distress. Scalable, low-intensity interventions such as WHO Self-Help Plus (SH+) show promise, yet evidence of their implementation and short-term effectiveness during active conflict is limited.
Methods
A multicenter longitudinal study was conducted across five universities. Students with mild-to-moderate distress (PSS-10) joined a 5-week offline Acceptance and Commitment Therapy-based SH+ course led by trained non-specialist facilitators. Outcomes included psychological distress (PHQ-9, GAD-7, PCL-5), well-being (WHO-5), daily functioning (WHODAS 2.0), and resilience (CD-RISC-10), assessed at baseline (T1), post-intervention (T2), and 3-month follow-up (T3). Analyses used non-parametric longitudinal tests on 297 completers.
Results
SH+ participation significantly reduced perceived stress, depression, anxiety, and post-traumatic stress from T1 to T2. Well-being and daily functioning improved, with all gains sustained at T3. Resilience remained stable. Implementation barriers included security threats, power outages, and exam overlaps, contributing to attrition.
Conclusions
WHO SH+ is an effective, scalable first-line psychosocial intervention for university students in wartime. It alleviates distress, enhances functioning, and maintains benefits over 3 months. SH+ can be rapidly deployed by non-specialists within stepped-care university frameworks during humanitarian crises. Flexible delivery and alignment with academic schedules are essential to overcome conflict-driven barriers.
Major depressive disorder is not a single, uniform condition. Different causes of depression produce distinct symptom patterns, creating discrete subtypes. The human capacity for mood variation evolved because it once offered adaptive benefits, but rapid cultural change has created a mismatch between ancestral and modern environments, making some traits that used to be beneficial maladaptive in contemporary environments. An evolutionary framework suggests that systemic inflammation, chronic stress, and gut dysbiosis can intensify symptoms and prolong adaptive mood states into maladaptive depression episodes.This book demonstrates that lifestyle interventions can be effective in both preventing and treating depression. After critically evaluating current treatments, Markus J. Rantala and Severi Luoto argue for individualized treatment approaches. They propose a new hypothesis for depression founded in evolutionary science. Written for researchers, clinicians, and informed readers, the book challenges how depression is currently diagnosed and treated.
Multiple birth fathers remain largely invisible in perinatal research, policy and practice, despite facing distinctive practical, emotional and financial challenges. This study explores the early parenting experiences of multiple birth fathers in the United Kingdom using qualitative survey data from 107 participants, analysed using thematic analysis. Drawing on a social capital framework, it examines how access to structural, relational and cognitive resources shapes fathers’ wellbeing. Four themes were identified: the complexities of early multiple birth fatherhood, fathers’ mental health, the visibility of their needs, and experiences of support. Fathers described the intensity of raising multiples as ‘doubly hard’, characterized by exhaustion, financial strain, and ‘survival mode’ in the first year. Many reported significant mental health challenges, including stress, guilt, and feelings of being ‘stretched to breaking point’, yet often did not seek support or found available services generic and unhelpful. Experiences of support were inconsistent: while some benefited from flexible employers or strong social networks, others reported minimal professional engagement and perceived services as primarily mother–focused. Peer support from other multiple birth parents was valued but not always accessible. Access to structural resources such as paternity leave, financial support and tailored services was limited, while relational and cognitive resources, including shared understanding from professionals and peers, were uneven. Although UK-based, these findings reflect wider international gaps in father-inclusive perinatal care. Greater recognition of multiple birth fathers, alongside tailored mental health support and multiples-specific services, is needed to improve outcomes for families with multiples.
The prevailing paradigm used by most researchers and physicians to understand depression appears myopic and deficient, and the treatments derived from it are ineffective. A broader perspective is required for understanding why people in contemporary societies are vulnerable to chronic depression. Evolutionary psychoneuroimmunology synthesizes insights from evolutionary biology, evolutionary psychiatry, neuroscience, immunology, and psychology to provide a broad scientific framework for understanding the relatively high prevalence of depression in people with contemporary western lifestyles. A range of findings indicates that the mismatch between the environments in which Homo sapiens evolved and the environments it currently habits – characterized by sedentary lifestyles, obesogenic diets, fragmented communities, loneliness – contributes in several ways to depression prevalence in contemporary societies. Understanding depression in contemporary Homo sapiens requires not just analyzing the proximate mechanisms contributing to it, such as chronic stress, poor diet, and low-grade systemic inflammation, but also the evolutionary question of why a mind that has undergone hundreds of thousands of years of evolution can be so vulnerable to such severe and debilitating mental health problems. Tinbergen’s four questions, a fundamental conceptual framework used in ethology, evolutionary biology, and evolutionary psychology, organizes these different levels of analysis in a coherent framework for this book.
This chapter normalizes failure as a routine part of AI research and of the PhD itself. It describes how setbacks can appear as technical breakdowns, weak results, conceptual dead ends, or stalled momentum, and explains why these experiences often feel personal even when they are structurally built into research. The chapter offers a simple way to diagnose “stuckness” and outlines practical responses: simplify and test assumptions when experiments misbehave, step back and reframe when the question no longer holds, restore structure when process slips, and prioritize recovery when motivation collapses. It also reframes rejection as feedback and encourages documenting failures so they become reusable knowledge rather than repeated pain.
Chapter 5 examines ‘restrictive practices’ and their legal and ethical implications for nurses. Restrictive practices are actions that restrict a person’s freedom of movement, such as locking the person in a room, secluding them by confining them to a physical space, putting them in manacles or straps, medicating them or directly holding them to restrict their movement. These practices can only be carried out as a last resort to protect the patient or another person, and must be authorised by a medical practitioner. A patient subject to restrictive practices must be observed closely at all times. In years past, the use of physical restraints in a clinical setting was not uncommon and included tying a person to a chair with a sheet, or tying the hands of a bed-bound person to the side of the bed. Besides any obvious cruelty, these practices were known to result in death by strangulation, falls, head injuries, lacerations and tissue necrosis. Nurses who use unauthorised restrictive practices may be liable for charges of kidnapping, assault and battery and, in the worst case, manslaughter.
Extremism is often regarded as an exceptional or pathological state, typically associated with ideology, violence, or deviance. Yet psychological extremism can also emerge in the rhythms of ordinary life – through devotion to work, relationships, parenting, wellness, or digital identity. This chapter reframes extremism as a motivational imbalance, a condition in which a single need dominates attention, suppressing alternative needs and relaxing their constraints on behavior. Such imbalance may lead to rigidity, burnout, and suffering when behavior chosen to address the dominant need undermines other fundamental concerns. Drawing on empirical research and theoretical models of significance-seeking, goal systems, and self-complexity, the chapter illustrates how modern environments – shaped by media algorithms, economic pressure, and norms – can amplify extreme behavior without ideology or coercion. Also explored are early indicators of imbalance and the psychological and social mechanisms that sustain it. The chapter concludes by proposing interventions to redirect the need for significance toward more pluralistic, flexible, and sustainable engagement.
Autistic adults experience high rates of co-occurring mental health difficulties, yet little is known about their representation within secondary adult mental health services. This study aimed to examine the actual prevalence and clinical presentation of autistic adults attending a community general adult mental health service in Ireland.
Methods:
A cross-sectional retrospective chart review was conducted in July 2023 within a community-based secondary mental health service serving a population of 92,610. Demographic characteristics, autism-related factors, diagnoses, self-harm/suicidality, and multidisciplinary service utilisation were extracted and analysed using descriptive and inferential statistics.
Results:
Forty autistic service users were identified among a total caseload of 1,270 (3.1%). The median age was 23 years, and 67.5% were male. Most autism diagnoses (65%) were made through Child and Adolescent Mental Health Services. Psychotic disorders were the most common psychiatric diagnosis (30%), followed by mood and anxiety disorders. Over half (52.5%) had a history of self-harm and/or suicidality, and 17.5% had required psychiatric inpatient admission. Although 95% were referred to at least one multidisciplinary team (MDT) service, 30% did not attend these appointments.
Conclusions:
Autistic adults represented a small proportion of service users despite their high burden of mental health difficulties, suggesting possible underrecognition of autism and barriers to accessing secondary mental health services. Those receiving care demonstrated complex clinical needs, including high rates of psychosis and suicidality. Improving autism recognition, developing integrated care pathways, and adapting multidisciplinary services to better meet autistic adults’ needs are essential to delivering equitable mental healthcare.
More than one billion people worldwide live with a mental health disorder, and rising prevalence continues to outpace the capacity of mental health services. Artificial intelligence, and large language models in particular, have been widely proposed as a remedy. Nevertheless, psychiatry’s limited mechanistic understanding of illness processes (compounded by their psychosocial roots) and its reliance on largely subjective clinical assessments limit what any artificial intelligence model can achieve. We examine where artificial intelligence genuinely helps, including large multimodal data-sets and administrative tools such as ambient scribes, and where evidence for direct therapeutic use remains preliminary and safety concerns are real. We also highlight risks posed by artificial intelligence to the research process itself, from hallucinated citations to unverifiable analysis pipelines. Ultimately, whether artificial intelligence comes to augment psychiatric care or hollow it out depends less on model capability than on the choices of stakeholders and policymakers.
This study examined how subjective disaster recovery and cancer-care satisfaction jointly shape family well-being in Japan, and when better cancer care accompanies higher well-being.
Methods
A quota-stratified web survey of 2,179 adults aged 20-69 was conducted across Japan (September 2019), with quotas by Fukushima residency and family cancer experience. Subjective recovery from any major disaster within 10 years (unexposed; recovered or in prospect; no prospect), household cancer experience, and Short FAMCARE satisfaction were modeled against latent well-being by structural equation modeling.
Results
Among non-cancer households (n = 1,324), unrecovered damage was associated with lower well-being (β = −0.08, 95% CI −0.13 to −0.03, P = 0.001), with no association in cancer-affected households (β = 0.00, P = 0.98). Among cancer-affected families (n = 855), high satisfaction was associated with higher well-being (β = 0.17, P < 0.001), more so in recovered than unrecovered households (contrast 0.149, 95% CI 0.031 to 0.268, P = 0.014). Resting on small subgroups, this interaction is exploratory.
Conclusions
Better cancer care did not offset incomplete disaster recovery; its association with higher well-being was confined to households with recovery achieved or in prospect. These cross-sectional findings are consistent with delivering reconstruction and cancer care together.
Disasters, large-scale crises, and prolonged adversities such as pandemics can place sustained psychosocial pressure on families and disrupt everyday family functioning. Although family resilience is increasingly used to explain why some families adapt better than others, the evidence base is dispersed across conceptual, empirical, and intervention-focused work.
Methods
We searched PubMed, Scopus, and Web of Science and included peer-reviewed studies that examined family resilience or family coping in disaster, pandemic, or sustained adversity contexts. Study selection followed PRISMA 2020 principles. Data were extracted using a standardized form and synthesized using narrative and thematic approaches.
Results
Forty-two studies were included in the qualitative synthesis. Across contexts, family resilience was most often described as a dynamic, system-level process that involves shared meaning-making, organizational flexibility, and effective communication. Parenting practices repeatedly emerged as a key pathway linking family resilience to child adjustment. Resilience-oriented family interventions reported overall beneficial effects across disaster, pandemic, and serious illness contexts, with no evidence of harm.
Conclusions
Family resilience is a critical contributor to psychosocial adaptation during disasters and large-scale crises. Interventions that strengthen family-level processes—especially communication, coping skills, and supportive parenting—may offer a scalable approach to improve preparedness, response, and longer-term recovery.
Governments spend billions on our behalf. But how should this money be spent? The purpose should be to increase the wellbeing of the people. So the best policies are those which produce the most wellbeing per pound spent. The new science of wellbeing now enables us to make these calculations. The authors of this book, led by Richard Layard, do just that across a whole range of government policies. And the results call for radical changes in priorities. This path-breaking book opens up a new approach to policy-making. It combines traditional economics with the new psychology of happiness. By valuing non-monetary outcomes it does what politicians have always wanted. Its methods have already been adopted by the UK Treasury and are relevant worldwide. If followed, they would produce a happier world. When people ask where do we go 'beyond GDP', this is the answer.
The European Psychiatric Association (EPA) undertook a study to investigate treatment preferences of European psychiatrists towards Bipolar Disorder (BD), as part of the Ambassador programme series of surveys.
Methods
We conducted a cross-sectional online survey among psychiatrists and psychiatry trainees from 40 European countries. The questionnaire contained clinical vignettes of different phases of BD including manic, rapid cycling, mixed, hypomanic, and depressive episodes, for both initial and subsequent treatment strategies.
Results
The final sample consisted of 654 participants, from Central and Eastern Europe (CEE), Southern Europe (SE), Northern Europe (NE), and Western Europe (WE). The majority preferred pharmacotherapy, most commonly as a combination of two or three drugs to treat all phases of the BD, with lithium being the most preferred option in all phases.
Among antipsychotics, olanzapine and quetiapine were the most commonly chosen. Antidepressants were applied in almost 20% of responses for the depressive phase. Psychosocial interventions were not systematically implemented, particularly during manic and mixed episodes, but when recommended, the most common approaches included psychoeducation, cognitive behavioural therapy (CBT) in up to 40% in depressive phase, and lifestyle recommendations. However, latent class analysis identified four different classes of prescribers.
Conclusions
Psychiatrists showed broadly similar pharmacological treatment preferences for BD, with frequent use of lithium-based combination therapies and limited implementation of psychosocial interventions, although latent class analysis revealed distinct prescribing profiles. These findings support the need for enhanced dissemination of evidence-based guidelines and greater integration of psychosocial approaches in BD care.
Early intervention increases the likelihood of eating disorder recovery but many young people delay help-seeking. We developed a smartphone-friendly, online decision-making tool to address this gap (FREED-Mobile (FREED-M)).
Aims
To conduct a randomised controlled feasibility trial of the FREED-M decision-making tool with 16- to 25-year-olds with a suspected eating disorder and no previous treatment for this.
Method
Participants were randomly allocated to FREED-M or an active control in a parallel group, two-arm trial. Outcomes were measured at weeks 0 (baseline), 4 (post-intervention) and 12 (follow-up). The primary feasibility outcome was attrition at follow-up. Other outcomes included motivational, clinical and economic measures.
Results
We over-recruited with 204 randomised participants (including 20 fraudulent participants). Main analyses were conducted with 184 genuine responders (FREED-M: n = 91, control: n = 93). At baseline, participants’ mean age was 21.0 (s.d. 2.0) years, 89% identified as female and 64% as White. Mean body mass index was 23.1 kg/m2 (6.3). N = 83 participants had an anorexia nervosa-like disorder, 101 had another eating disorder or high eating disorder risk. Attrition at week 12 was n = 112 (61%). Of the n = 42 FREED-M participants who provided acceptability ratings, 79% liked the intervention and 66% found it useful. Between-group effect sizes for motivation and readiness to change were small to medium at 4 weeks (d = 0.27 and d = 0.15, respectively) favouring FREED-M, but differences were not sustained at follow-up (d = −0.02 and d = −0.12, respectively).
Discussions
Although the attrition rate was high, recruitment exceeded expectations. Acceptability of FREED-M was high among participants who provided acceptability ratings. Motivation/readiness to change and help-seeking are candidates for primary outcomes in a future randomised controlled trial.
