The NHS is no longer a virtual monopoly provider of mental health residential care. This makes it difficult to assess the volume, range and adequacy of local provision.

Local data collectors used standard instruments to collect detailed information about 368 facilities (with 1951 residents) providing mental health residential care in eight districts. Because local definitions were inconsistent, facilities were reclassified on the basis of facility size and extent of day and night cover. The eight categories of accommodation are compared on levels of staffing, staff qualifications and the characteristics of their residents.

There was a nearly threefold variation between districts in the total number of residential places available per unit of population, and even greater variation in the number of places with 24-hour waking cover. Most residents have long-term, severe mental illness and severe impairment. Long-stay wards accommodate people who pose greater risk of violence than do the two types of non-hospital facility with 24-hour waking cover (P<0.001). The former also employ a much greater proportion of staff with formal care qualifications and, in particular, nursing qualifications than the latter (49% v. 15%, P < 0.001).

It is suggested that one consequence of the diversification in provision of mental health residential accommodation has been a relative reduction in the proportion of provision available to the most severely disabled. This might apply particularly to those who pose a risk of acting violently.

Auditory verbal hallucinations are thought to arise from the disordered monitoring of inner speech (thinking in words). We tested the hypothesis that a predisposition to verbal auditory hallucinations would be associated with an abnormal pattern of brain activation during tasks which involved the generation and monitoring of inner speech.

The neural correlates of tasks which engaged inner speech and auditory verbal imagery were examined using positron emission tomography in (a) schizophrenic patients with a strong predisposition to auditory verbal hallucinations (hallucinators), (b) schizophrenic patients with no history of hallucinations (nonhallucinators), and (c) normal controls.

There were few between-group differences in activation during the inner speech task. However, when imagining sentences spoken in another person's voice, which entails the monitoring of inner speech, hallucinators showed reduced activation in the left middle temporal gyrus and the rostral supplementary motor area, regions which were strongly activated by both normal subjects and nonhallucinators (P<0.001). Conversely, when nonhallucinators imagined speech, they differed from both hallucinators and controls in showing reduced activation in the right parietal operculum.

A predisposition to verbal hallucinations in schizophrenia is associated with a failure to activate areas implicated in the normal monitoring of inner speech, whereas the absence of a history of hallucinations may be linked to reduced activation in an area concerned with verbal prosody.

Unipolar and bipolar patients with a chronic illness pattern were investigated to determine whether they experienced a higher number of life events prior to the onset of recurrent affective episodes.

The study participants consisted of 27 recovered bipolar patients, 24 recovered unipolar patients and 26 healthy control subjects. Life events and psychiatric status were assessed by bimonthly interviews over the period of one year using the Inventory for Recent Life Events and the Research Diagnostic Criteria.

In both unipolar and bipolar patients, analyses revealed no significant differences in the number of life events experienced, irrespective of whether the patients had presented with a depressive episode of at least minor intensity during the study (all P > 0.1). Specifically, an increase in marital problems was observed in bipolar patients prior to the onset of recurrent hypomanic and manic episodes (P=0.06).

The causal association between life events and the onset of depression, shown to be relevant in non-chronically depressed subjects, does not apply in chronic affective disorders. In addition, our results suggest that marital events have an impact on the onset of recurrent hypomanic and manic episodes.

Literature and clinical experience suggest that some people experience atypical, complicated or pathological bereavement reactions in response to a major loss.

Three groups of community-based bereaved subjects – spouses (n=44), adult children (n=40), and parents (n=36) – were followed up four times in the 13 months after a loss. A 17-item scale of core bereavement times was developed and used to investigate the intensity of the bereavement response over time.

Cluster analysis revealed a pattern of bereavement-related symptoms approximating a syndrome of chronic grief in 11 (9.2%) of the 120 subjects. None of the respondents displayed a pattern consistent with delayed or absent grief.

In a non-clinical community sample of bereaved people, delayed or absent grief is infrequently seen, unlike chronic grief, which is demonstrated in a minority.

The police are the gatekeepers to the criminal justice system (CJS). It is agreed that where possible mentally ill people should be diverted to psychiatric care. The purpose of this investigation was to determine what factors were associated with the entry of obviously mentally ill people into the CJS.

The population of all detainees arrested in seven London police stations was observed to determine the presence of obvious mental illness. All detainees regarded as ill or known to have significant psychiatric histories were followed through the CJS to court disposal. Defendants diagnosed as psychotic by court liaison psychiatrists were identified and the circumstances of their arrest and detention examined.

Of all police detainees observed, 1.4% were found to be acutely ill. Diversion of obviously ill detainees was common practice. The factor most strongly associated with entry to the CJS was the presence of violence at time of arrest. Other factors were the persistence of (petty) offending and the operation of court warrants issued as a result of the person's failure to appear at court when required to do so.

Both police and courts are well aware of the inappropriateness of custody for acutely ill people and efforts are made to divert such people out of the CJS. Persistent petty offenders are often being recycled from the street to police station to court and back to the street without the benefit of care. A dedicated facility is recommended in central London to meet this need.

Depressed patients are often characterised by marital distress, but few studies investigate the effects of marital therapy on depressed mood and relationship dysfunction.

Twenty-seven depressed patients experiencing marital distress were randomly assigned to either individual behavioural–cognitive therapy or marital therapy. The individual treatment condition focused on depressed mood, behavioural activity and dysfunctional cognitions, whereas in the marital condition the partner was involved in the treatment and the focus was on the communication process in the marital relationship. MANOVAs revealed that treatment led to statistically significant improvements in depressed mood, behavioural activity and dysfunctional cognitions, an increase in relationship satisfaction and improvement of communication in patients and spouses. A significant interaction effect was found, showing that marital therapy had more impact on relationship variables than the individual treatment.

Both individual cognitive–behaviour therapy and marital therapy lead to less depressive complaints, and both treatment conditions have a positive effect on the relationship, although the effect on the relationship is significantly stronger in couples who were treated by marital therapy compared with patients who were treated individually.

Hypochondriasis is a distressing disorder for which there is no adequate established treatment. This study evaluates the effect of cognitive–behavioural treatment of hypochondriasis, compared with a waiting list control.

Thirty-two patients were randomly assigned to either cognitive–behavioural therapy or a no treatment waiting list control. Cognitive–behavioural treatment consisted of 16 individual treatment sessions over a four-month period. The waiting list control lasted for four months and was followed by 16 sessions of cognitive–behavioural treatment. Assessments were made before allocation and after treatment or waiting list control. Patients who had cognitive–behavioural treatment were reassessed three months after completion of treatment.

Paired comparisons on post-treatment/wait scores indicated that the cognitive–behavioural group showed significantly greater improvements than the waiting list on all but one patient rating, all therapist ratings and all assessor ratings. After three months the benefits of therapy were maintained.

Cognitive–behavioural treatment is an effective therapy for hypochondriasis. Implications of the study are discussed.

Body dysmorphic disorder (BDD) consists of a preoccupation with an ‘imagined’ defect in appearance which causes significant distress or impairment in functioning. There has been little previous research into BDD. This study replicates a survey from the USA in a UK population and evaluates specific measures of BDD.

Cross-sectional interview survey of 50 patients who satisfied DSM–IV criteria for BDD as their primary disorder.

The average age at onset was late adolescence and a large proportion of patients were either single or divorced. Three-quarters of the sample were female. There was a high degree of comorbidity with the most common additional Axis I diagnosis being either a mood disorder (26%), social phobia (16%) or obsessive–compulsive disorder (6%). Twenty-four per cent had made a suicide attempt in the past. Personality disorders were present in 72% of patients, the most common being paranoid, avoidant and obsessive–compulsive.

BDD patients had a high associated comorbidity and previous suicide attempts. BDD is a chronic handicapping disorder and patients are not being adequately identified or treated by health professionals.

Deliberate self-harm (DSH) is common in adolescents in the United Kingdom and suicide has greatly increased in frequency in older male adolescents. There is, however, very little information about DSH in older children and young adolescents.

Analysis of data collected by the Oxford Monitoring System for Attempted Suicide between 1976 and 1993 for all cases of DSH in under 16-year-olds referred to the general hospital in Oxford.

Seven hundred and fifty-five individuals were involved in 854 episodes of DSH. There were very few cases under 12 years of age but after that the behaviour increased greatly in frequency with each year of age, especially in girls. Eighty-five per cent were girls, the sex ratio being 5.7 girls to each boy. Most cases involved self-poisoning. During the final six years of the study period paracetamol was involved in 54.7% of overdoses, compared with 19.5% in 1976–1981. A minority of individuals had had previous psychiatric treatment. The most frequent problems were relationship difficulties with parents, followed by difficulties with friends, school and social isolation. Among those who reported previous episodes of DSH, in the majority of cases these had not come to medical attention. Repetition of self-harm occurred in 9.4% of cases within a year of an episode and 19.3% during the overall study period. There was some indication that repetition was most common in youngsters discharged from the Accident and Emergency Department without a psychiatric assessment.

DSH in under 16-year-olds is not uncommon and there is evidence that it occurs far more frequently in the community than is reflected in general hospital figures. The problem of paracetamol self-poisoning in this age group needs to be addressed. A psychiatric assessment should be performed in all cases coming to the general hospital.

The aim was an investigation of the symptom composition of the negative syndrome of schizophrenia.

A hundred schizophrenic patients were assessed with various rating scales for positive and negative symptoms and typological criteria. A subgroup with a negative syndrome was defined, and a discriminant analysis performed using symptoms from the Scale for the Assessment of Negative Symptoms (SANS) as discriminant variables.

The discriminant function classified 92% of patients correctly. All but four SANS symptoms (inappropriate affect, both attentional items and blocking) were significantly correlated with the discriminant function.

With the exception of some items, the SANS seems to capture adequately the negative syndrome of schizophrenia.

For many common medical and neuropsychiatric disorders, early age at onset reflects high familial liability to illness. However, for schizophrenia, most studies do not find such a relationship.

Using Cox proportional hazard models, we investigate this question in the epidemiologically-based Roscommon family study.

No relationship was found between age at onset in schizophrenic probands and the hazard rate for schizophrenia in their relatives. Similar results were obtained when the definition of illness was expanded to include schizoaffective disorder and other non-affective psychoses.

For schizophrenia, a ‘common-sense’ model for age of onset (i.e. those with highest familial liability to illness succumb first while those with lower liability survive longer before falling ill) does not seem to apply. Our results are more consistent with a model in which variation in age at onset of schizophrenia is due to random developmental effects or to environmental experiences unique to the individual.

Maladaptive behaviours are frequently present in individuals with learning disabilities; however, their prevalence varies between studies and the aetiology, classification and most appropriate management of such behaviours remain unclear. The aims of the study were twofold: firstly to determine the prevalence of maladaptive behaviours, and secondly to develop a classification typology.

A population of 2202 adults with learning disabilities was surveyed to determine the prevalence of maladaptive behaviours. These were subjected on the basis of 13 behavioural characteristics to cluster analysis. The clusters were further examined in respect of secondary variables.

Over 60% of individuals demonstrated the presence of at least one maladaptive behaviour and in 40% this problem was of either severe degree or frequent occurrence. Men were more likely to demonstrate physical aggression, property destruction, tantrums and verbal abuse than women. Although some severe maladaptive behaviours diminished with age, many persisted through all age groups. Six behavioural clusters were devised which demonstrated face validity and which differed in respect of demographic and developmental variables, and the prevalence of maladaptive habits and autistic symptoms.

These findings demonstrate a high prevalence of maladaptive behaviours and ‘objectionable habits’ among people with learning disabilities. A classification of behavioural symptoms may be possible on the basis of symptom clusters.

An epidemiological survey of childhood autism as defined in ICD–10 Research Criteria was conducted in the northern part of Yokohama, Japan.

The routine health checkup for 18-month-old children served as the initial mass-screening, and all facilities which provide child care services function to detect all cases with childhood autism and refer them to the Yokohama Rehabilitation Centre. Cumulative incidence of childhood autism up to 5 years of age among the birth cohort of 1988, and prevalence on 1 January 1994, among residents born in 1988 were estimated.

Cumulative incidence and prevalence were 16.2 per 10 000 and 21.1 per 10 000, respectively. Children with high-functioning autism who had IQs of 70 and over constituted approximately half of all the children with childhood autism.

It was confirmed through better detection of high-functioning cases that childhood autism in Japan is more common than formerly estimated.

The aim of this study was to determine the association between physical and psychiatric morbidity among general practice patients and to explore the influence of possible intervening variables.

Physical and psychiatric morbidity in 1620 consecutive patients attending their general practitioner (GP) was assessed using a two-stage design. Ninety-four per cent of the patients (n=1523) were successfully screened using the General Health Questionnaire (GHQ–12); 428 of the 602 patients (71%) eligible for the second stage were interviewed using the Composite International Diagnostic Instrument adapted for use in primary health care (CIDI–PHC), the Brief Disability Questionnaire (BDQ) and the Groningen Social Disability Schedule (GSDS) to assess psychiatric, physical and social status. Assessments of physical and psychiatric morbidity were also obtained from the patients' GPs.

There was a significant association between physical and psychiatric morbidity, although patients with four symptoms or less of physical illness were no more likely to be psychiatric cases than those with none. The association was accounted for by patients at the severe end of the physical continuum with five or more medically explained somatic symptoms: these were twice as likely to be psychiatric cases as those with no such symptoms. Female gender, social disability and physical disability were all significantly more likely to be associated with psychiatric disorder, whether measured by GP or research interview; and these relationships remained after the data were corrected for age differences.

Patients in general practice with moderate to severe physical morbidity are at increased risk of developing psychiatric illness, and when medical illness is present, psychiatric symptoms are more severe. As physical and psychiatric comorbidity is relatively common in general practice, the specific needs of these patients should receive greater attention.

Reports of an association between restriction fragment length polymorphisms (RFLPs) at the dopamine D2 receptor (DRD2) locus and alcoholism have suggested involvement of that locus in the aetiology of alcoholism.

Sib pair linkage analyses were conducted in families multiply affected by alcoholism, using both the Taql ‘A’ RFLP and a microsatellite repeat polymorphism at the DRD2 locus.

The ‘Identical By Descent’ analysis provided significant evidence of an effect of the DRD2 locus on the liability to develop heavy drinking (P<0.0016) and Research Diagnostic Criteria alcoholism (P<0.0003) in the first sample of families studied. However, this result was explicable by the segregation of alleles in a single large sibship, and it was not replicated in a second sample of families.

The results do not support linkage between the DRD2 locus and alcoholism in most of the families studied. It remains possible that this locus influences the predisposition to alcoholism in some families.
