Many countries have set targets for suicide reduction, and suggested that mental health care providers and general practitioners have a key role to play.

A systematic review of the literature.

Among those in the general population who commit suicide, up to 41% may have contact with psychiatric inpatient care in the year prior to death and up to 9% may commit suicide within one day of discharge. The corresponding figures are 11 and 4% for community-based psychiatric care and 83 and 20% for general practitioners.

Among those who die by suicide, contact with health services is common before death. This is a necessary but not sufficient condition for clinicians to intervene. More work is needed to determine whether these people show characteristic patterns of care and/or particular risk factors which would enable a targeted approach to be developed to assist clinicians in detecting and managing high-risk patients.

The role of viruses in the aetiology of both chronic fatigue syndrome (CFS) and depressive illness is uncertain.

A prospective cohort study of 250 primary care patients, presenting with glandular fever or an ordinary upper respiratory tract infection (URTI).

The incidence of an acute fatigue syndrome was 47% at onset, after glandular fever, compared with 20% with an ordinary URTI (relative risk 2.3, 95% CI 1.3–4.1). The acute fatigue syndrome lasted a median (interquartile range) of eight weeks (4–16) after glandular fever, but only three weeks (2–4) after an URTI. The prevalence of CFS was 9–22% six months after glandular fever, compared with 0–6% following an ordinary URTI, with relative risks of 2.7–5.1. The most conservative measure of the incidence of CFS was 9% after glandular fever, compared with no cases after an URTI. A conservative estimate is that glandular fever accounts for 3113 (95% C11698–4528) new cases of CFS per annum in England and Wales. New episodes of major depressive disorder were triggered by infection, especially the Epstein – Barr virus, but lasted a median of only three weeks. No psychiatric disorder was significantly more prevalent six months after onset than before.

Glandular fever is a significant risk factor for both acute and chronic fatigue syndromes. Transient new major depressive disorders occur close to onset, but are not related to any particular infection if they last more than a month.

The dose – effect relationships of cumulative trauma to the psychiatric symptoms of major depression and post-traumatic stress disorder (PTSD) in a community study of Cambodian survivors of mass violence were evaluated.

In 1990, a survey of 1000 households was conducted in aThai refugee camp (Site 2) using a multi-stage random sampling design. Trauma history and psychiatric symptoms were assessed for two time periods. Analysis used linear dose – response regression modelling.

993 Cambodian adults reported a mean of 14 Pol Pot era trauma events and 1.3 trauma events during the past year. Symptom categories of depression, PTSD, dissociative and culturally dependent symptoms exhibited strong dose – effect responses with the exception of avoidance. All symptom categories, except avoidant symptoms, were highly correlated.

Cumulative trauma continued to affect psychiatric symptom levels a decade after the original trauma events. The diagnostic validity of PTSD criteria, with the notable exception of avoidance, was supported. Inclusion of dissociative and culturally dependent symptoms increased the cultural sensitivity of PTSD.

It is not known why the most common mental disorders, anxiety and depression, are more prevalent among women than men. The aim was to test the hypothesis that this gender difference could be explained by differences between men and women in social role occupancy, after adjusting for age and socio-economic status.

A cross-sectional survey of 8979 adults aged 16–74 years living in private households in England. Wales and Scotland was carried out. Prevalence of common mental disorders was assessed using the General Health Questionnaire.

The gender difference in the prevalence of the common mental disorders (unlike social role occupancy) did not vary with age to a statistically significant degree (unadjusted odds ratio 1.35, 95% C11.23–1.48) (P < 0.0001). Although those of either gender occupying the fewest, and women occupying the most social roles (after adjusting for age) had the highest prevalence of common mental disorders, neither number of social roles, occupancy of traditional ‘female’ caring and domestic roles, nor socio-economic status explained the gender difference in these conditions (adjusted OR 1.26, 95% C11.14–1.41) (P < 0.001).

The gender difference in the prevalence of the common mental disorders is not explained by differences between men and women in the number or type of social roles occupied.

Recent research suggests that high familial loading is associated with early onset of schizophrenia. Results concerning outcome have been controversial.

We assessed the relationship between familial loading, age at onset and outcome in all Finnish patients with schizophrenia born between 1950 and 1969. Patients and their first-degree relatives were identified using nationwide registers. Familial loading scores were calculated for schizophrenia and for combined psychotic disorders, and patients were accordingly classified into three groups: high (n = 761), intermediate (n = 14 247), and low familial loading (n = 725). Linear mixed models and the Cox proportional hazard model were used in the analyses.

Onset was earliest, hospitalisation longest and risk of retirement in receipt of a disability pension highest in the group with high familial loading, with opposite extremes found in the group with low familial loading.

High familial loading for schizophrenia is associated with early onset and poor outcome of schizophrenia.

The objective is to estimate parameters of the natural history of panic disorder, including its prodrome, incidence, recovery and recurrence.

In 1981 the Baltimore Epidemiologic Catchment Area Study interviewed 3481 individuals probabilistically selected from the household population. During 1993–1996, 1920 of these individuals (73% of survivors) were interviewed again. Baseline and follow-up interviews included the National Institute of Mental Health Diagnostic Interview Schedule. During the follow-up, a subsample was assessed by psychiatrists using the World Health Organization Schedules for Clinical Assessment in Neuropsychiatry (SCAN).

There were 35 new cases of panic disorder in 24 475 person years of exposure, yielding an annual incidence of 1.43 per 1000 per year. Data from the SCAN assessments suggest the incidence estimate is conservative. Incidence is greater in females and declines with age. About one-third of the new cases arise without agoraphobia, but about half have anxiety of some sort present for many years prior to meeting criteria for diagnosis. People with agoraphobia have less intense onsets but slower recoveries than those without agoraphobia.

Panic is heterogeneous in its pattern of onset and recovery. Some of the heterogeneity is associated with the presence of other anxiety over a long period of the life.

Little is known about psychiatric disorders in adolescents who attend primary care.

Prospective study of 13- to 16-year-olds consecutively attending general practice. Information was obtained from adolescents, parents and general practitioners, using questionnaires and research interviews.

136/200 (68%) of adolescent attenders took part. Two per cent presented with psychiatric complaints. From research interviews with adolescents, psychiatric disorder in the previous year was found in 38%, with moderate impairment of functioning in over half (according to Children's Global Assessment Scale scores). Most disorders (42/50, 84%) were emotional (‘internalising’) disorders. Psychiatric disorders were significantly associated with high levels and intensity of physical symptoms and with increased health risks. General practitioner assessment of psychiatric disorders was low on sensitivity (20.8%) but high on specificity (90.7%). Doctors identified most severely affected adolescents.

Depressive and anxiety disorders are common among adolescent general practice attenders and linked to increased physical symptoms; general practitioner recognition is limited.

Mania with chronic course has been overlooked in the recent literature. Our aim was clinically to characterise and validate this form of mania.

We evaluated 155 people with DSM–III–R mania and assessed their family history, temperament, symptomatology and course. We used a semi-structured interview for mood disorders, as well as the Comprehensive Psychopathological Rating Scale and the Scale for the Assessment of Positive Symptoms.

Twenty (13%) had a chronic course arising from a background of hyperthymic temperament and recurrent mania, with a deteriorative pattern. Clinically, they were characterised by a significantly high rate of almost constant euphoria, grandiose delusions and related delusions, but had relatively low rates of sleep disturbance, psychomotor agitation and hypersexuality.

Even with current therapies a significant number of people with bipolar disorders have a deteriorative outcome associated with the gradual disappearance of acute mania with an increase in mregalomanic delusions, alienation from loved ones and decreased likelihood of medical and psychiatric care.

Aims of the Defeat Depression Campaign between 1991 and 1996 included the reduction of stigma associated with depression, education of the public about the disorder and its treatment and encouragement of earlier treatment-seeking. Newspaper and magazine articles, radio and television programmes and other media activities were employed.

Surveys of public attitudes were conducted by MORI in late 1991, early 1995 and mid-1997. Each covered approximately 2000 subjects, sampled to be representative of the population of Great Britain. Structured interviews covered views on depression, treatment and general practitioners (GPs).

There were significant positive changes regarding attitudes to depression, reported experience of it, attitudes to antidepressants, and less consistently, to treatment from GPs. Changes were of the order of 5–10%. Throughout, attitudes to depression and to treatment by counselling were very favourable, whereas antidepressants were regarded as addictive and less effective.

Positive attitude change was achieved during the Campaign, although there is still room for improvement in some aspects.

We aimed to examine the hypotheses that major depression is aetiologically heterogeneous consisting of a mixture of ‘genetic’ and ‘non-genetic’ forms or, alternatively, a mixture of one form that is ‘pure’ depression and another that has a familial relationship with alcohol dependency or other disorders.

One hundred and eleven twin pairs (44 monozygotic, 67 dizygotic) where the proband had received treatment for DSM–IV major depression were ascertained via a hospital register. Family history information on parents and siblings was obtained from the proband, co-twin or both. Diagnoses on parents and siblings were made blind to twin zygosity or concordance and compared in the relatives of concordant versus discordant twins.

The lifetime prevalence and age-corrected risk of depression were no different in the relatives of concordant and discordant twin pairs. There was a marginally significant increase in the rate of alcohol abuse or dependence among the relatives of concordant twins but no difference between concordant and discordant pairs in respect of other axis I diagnosis among family members.

The results argue against genetic heterogeneity and suggest that major depression cannot usefully be divided into genetic and non-genetic forms or into ‘pure’ depression and depression associated with other disorders such as alcohol dependency.

We investigated whether family history had prognostic significance in depression in a study which addressed some of the methodological shortcomings of previous studies.

We collected family history data on a consecutive series of 89 patients admitted with RDC major depression, blind to the outcome of the proband. This comprised 116, 283 and 120 first-degree relatives examined with the SADS–L, FH–RDC and case note data, respectively. The outcome of 74 of these probands (83%), previously categorised into four operationally defined groups, was then examined.

A positive family history of severe psychiatric illness (i.e. a relative with a history of either a psychosis, hospitalised depression or suicide) was associated with poor outcome in the proband. This association persisted after controlling for variable family size, age structure and gender. As family history was correlated with neither Kendell's neurotic/psychotic index nor the probands neuroticism score, an individual with high scores an all three would have a greatly increased chance of having a poor outcome.

A family history of severe psychiatric illness in a first-degree relative may be useful as one of the vulnerability factors for predicting poor long-term outcome in depression.

This study investigated three questions with major implications for suicide prevention: the sensitivity of the history of previous suicide attempt(s) as an indicator of suicide risk, the time interval from a preceding suicide attempt to the fatal one, and switching of suicide methods by those eventually completing suicide.

The lifetime history of suicide attempts and the methods the victims (n=1397) used were examined in a nationwide psychological autopsy study comprising all suicides in Finland within a 12-month research period in 1987–1988.

Overall, 56% of suicide victims were found to have died at their first suicide attempt, more males (62%) than females (38%). In 19% of males and 39% of females the victim had made a non-fatal attempt during the final year. Of the victims with previous attempts, 82% had used at least two different methods in their suicide attempts (the fatal included).

Most male and a substantial proportion of female suicides die in their first suicide attempt, a fact that necessitates early recognition of suicide risk, particularly among males. Recognition of periods of high suicide risk on the grounds of recent non-fatal suicide attempts is likely to be important for suicide prevention among females. Subjects completing suicide commonly switch from one suicide method to another, a finding that weakens but does not negate the credibility of restrictions on the availability of lethal methods as a preventive measure.
