All psychiatrists should be able to construct a psychodynamic formulation of a case. A key advantage of formulation over diagnosis is that it can be used to predict how an individual might respond in certain situations and to various psychotherapies. This article looks in some depth at what psychiatric trainees need to be taught about psychodynamic formulation. We introduce formulation in terms of four levels, each level corresponding to a different degree of theoretical and clinical sophistication and therefore to different trainees' needs. We use a case vignette to illustrate how a clinical situation might be formulated at each of these levels.

Pathological gambling has so far received scant attention in the psychiatric literature. It has a prevalence rate of about 1% in most countries, and with the deregulation of gambling in the UK the prevalence is set to rise here. Pathological gambling can adversely affect the individual, family and society, and also carries high rates of psychiatric comorbidity. Early identification and appropriate treatment can limit the long-term adverse consequences and improve outcome. This article reviews assessment techniques and tools, and treatment strategies for pathological gambling.

Substance use disorders are a frequent comorbidity in adult attention-deficit hyperactivity disorder (ADHD). This review discusses the relationship between adult ADHD and substance use disorder, including use of licit and illicit substances such as nicotine, alcohol, cocaine and cannabis. We discuss treatment studies in this area and provide a treatment algorithm to guide clinicians in the management of adult ADHD comorbid with different forms and severities of substance use disorder.

Attention-deficit hyperactivity disorder (ADHD) is a persistent, pervasive disorder characterised by symptoms of inattention, impulsivity and hyperactivity. Although traditionally considered a disorder of childhood, symptoms and associated impairments persist into adulthood for a significant proportion of individuals. Untreated ADHD can have a number of adverse effects for both the individual and wider society. Despite this, ADHD in adults is often misdiagnosed or its diagnosis is ‘missed’ in general psychiatric settings and this article highlights some reasons for this.

Knowledge management sounds superficially like yet another of those topical expressions describing something that has been developed outside medicine and is possibly ill-suited for application within the field, but offering an excuse for yet more change. However, one of the distinguishing features of every profession is that it applies a body of specialist knowledge and skills to a defined purpose. Knowledge in medicine is growing exponentially. In a recent survey of just 22 general practices, the practice guidelines identified weighed 28 kg (Hibble et al, 1998)! In psychiatry, about 5500 papers which potentially have clinical relevance are published annually. Keeping pace with knowledge as it grows is a major challenge for all clinicians. This is reflected in the National Health Service (NHS) information strategy, which identifies three specific needs of clinicians (NHS Executive, 1998). These are:

1. • fast, reliable and accurate information about patients in their care;

2. • access to knowledge to inform clinical practice;

3. • access to information to underpin evaluation of clinical practice, planning and research, clinical governance and continuing professional development.

Almost all psychiatric training programmes include a journal club. These clubs are experiencing a revival as a result of the introduction of a critical review paper into Part II of the MRCPsych examinations. Successful clubs are generally those with a single designated leader and mandatory attendance; provision of food is also helpful. A number of possible formats are discussed, designed to make the club an entertaining and stimulating experience.

Herbal remedies are used by many people suffering from anxiety or depression. It is therefore important to know whether they generate more good than harm. A systematic review of the published literature revealed trial data for Ginkgo biloba, Lavandula angustifolia, Hypericum perforatum, Valeriana officinalis, Crataegus oxyacantha, Eschscholzia californica, Matricaria recutita, Melissa officinalis, Passiflora incarnate and Piper methysticum. Only two of these herbal remedies are supported by sound evidence: Hypericum perforatum (St John's wort) for mild to moderate depression and Piper methysticum (kava) for anxiety. Neither is free of risks. Our knowledge of herbal remedies is incomplete and the subject merits rigorous study.

In the wake of the deinstitutionalisation of mental health services, community treatment orders (CTOs) have been introduced in around 75 jurisdictions worldwide. They make it a legal requirement for patients to adhere to treatment plans outside of hospital. To date, about 60 CTO outcome studies have been conducted. All studies with a methodology strong enough to infer causality conclude that CTOs do not have the intended effect of preventing relapse and reducing hospital admissions. Despite this, CTOs are still debated, possibly reflecting different attitudes to the role of evidence-based practice in community psychiatry. There are clinical, ethical, legal, economic and professional reasons why the current use of CTOs should be reconsidered.

This article outlines common psychodynamics in psychosis. We consider psychosis as a response to unbearable aspects of reality and illustrate how psychodynamic concepts of psychological defence can be used as a framework for understanding this. We also present a psychodynamic approach to understanding the development of psychosis, using the stress–vulnerability model, and discuss interpersonal dynamics in psychosis, particularly their relevance to therapeutic relationships and to interactions between patients and their families. The perspectives presented are intended to complement and enrich other frameworks rather than compete with them.

Home treatment as an alternative to acute adult in-patient care is part of the National Health Service Plan for mental health services in the UK. As a form of crisis intervention, it benefits from an understanding of, and ways of working with, the social systems relevant to the patient in crisis. This article reviews relevant terminology and background theory, and considers the social factors associated with psychiatric admission.

Conversion disorders tend to be poorly understood and diagnosis can be difficult. In this article, we aim to clarify what conversion disorders are and how they can be distinguished from other psychiatric disorders that involve physical symptoms. Prevalence, prognosis and relationship to organic disease are controversial areas; we outline what is known about them and provide some historical context. Aetiological theories and management strategies are discussed, the latter with the aid of case vignettes.

The health of family carers may affect not only their own lives but also the lives of the people for whom they provide care. This article describes how the caring role can affect the health and well-being of a carer of a person who has a mental or physical disorder. Suggestions are made about how to recognise and ameliorate some of the detrimental effects of the caring role on the carer's own health.

For nearly three decades, closure of large psychiatric and learning disability hospitals has continued and more people with mental health needs remain in the community. With this continuing decrease in hospital provision, there has been an increased focus on the development of systems of safe care and effective treatment for people with significant mental health problems living in the community. Attempts to make this a central plank of mental health care have been reflected in legislation and guidance produced by the Department of Health. The Care Programme Approach (CPA) was introduced in 1991 after the publication of HC (90) 23/LASSL (90) 11 and subsequent guidance from the White Paper Caring for People (Department of Health, 1990).

General principles of management of patients with personality disorders admitted in crises to the in-patient unit are discussed. The role of the acute ward in the overall plan of care, the clinical thresholds to consider in deciding whether admission is appropriate and the main elements of the in-patient care plan are outlined. The management of patients with borderline personality disorder, who constitute the majority of such admissions, is discussed in detail.

Sensory (visual and hearing) impairment has significant detrimental impact on sociocognitive and language development. Despite this, it is very much underrecognised and underdiagnosed in people with intellectual disability. Raising awareness of sensory impairment among professionals and carers is extremely important for early management to prevent further social handicap in people with intellectual disability. This article reviews sensory impairment in intellectual disability and its association with autism-spectrum disorder and mental illness.

Mental health professionals regard the assessment of suicide risk as part of normal clinical practice, but most shy away from assessment of risk of interpersonal violence, either doubting that such predictions are possible, or, if possible, are part of their role. In part, this fastidiousness reflects the influence of a consensus which emerged in the 1970s to the effect that there was no substantial relationship between mental illness and violent behaviour. The only basis for risk assessments which remained were those factors in the general population known to be associated with criminality. Even here, however, the accuracy of predictions made by clinicians had been subject to considerable critical scrutiny, which undermined any claims the profession may have had to expertise (Monahan, 1981; Brizer, 1989). There seems to have been wide acceptance that psychiatrists were doubly disabled in the business of predicting violence by having no relevant specialist knowledge and by being poor at applying knowledge gleaned from other disciplines such as criminology.

Sleep disorders are relevant to psychiatric practice in a number of ways, including the possibility that they may be misdiagnosed as fundamentally psychiatric conditions in patients of all ages. This risk exists in a wide range of collectively very common sleep disorders which need to be considered in explaining insomnia, excessive sleepiness or disturbed episodes of behaviour associated with sleep (parasomnias). Examples given include circadian sleep–wake cycle disorders (such as the delayed sleep phase syndrome), obstructive sleep apnoea, narcolepsy, Kleine–Levin syndrome, sleep paralysis and rapid eye movement (REM) sleep behaviour disorder. Failure to recognise and treat such disorders is likely to cause and perpetuate psychological problems. Correct recognition requires familiarity with the range and manifestations of sleep disorders.

Homeless families are defined as all adults with dependent children who are statutorily accepted by local authorities (housing departments) in the UK, and are usually accommodated for a brief period in voluntary agency, local authority or housing association hostels. This period varies from a few days to several months, although the target for rehousing is usually around 4 to 6 weeks. Some housing departments, particularly in London, also use bed and breakfast accommodation.

During the past decade, increasing attention has been paid to the primary care level of service for children and adolescents with mental health problems. In particular, a number of national reports have advised service commissioners and providers to increase the amount of specialist child and adolescent mental health services (CAMHS) support to primary care colleagues (Department of Health/Department for Education/Social Services Inspectorate, 1995; National Health Service (NHS)/Health Advisory Service (HAS), 1995; Audit Commission, 1999).

Health anxiety is an important new diagnosis that is increasing in frequency because of changing attitudes towards health, particularly excessive use of health information on the internet (cyberchondria). People with abnormal health anxiety become over-diligent monitors of their health, misinterpret most somatic sensations as evidence of disease, consult medical professionals unnecessarily and frequently, and are often over-investigated. Relatively few patients with health anxiety present to psychiatrists; most are seen in primary and secondary medical care. This paper reviews the diagnosis and presenting features of health anxiety, its identification in practice and its treatment. A range of simple psychological treatments have been shown to have long-lasting benefit for the disorder but are greatly under-used.
