The International Pilot Study of Schizophrenia: five-year follow-up findings.

A five-year follow-up of the patients initially included in the International Pilot Study of Schizophrenia was conducted in eight of the nine centres. Adequate information was obtained for 807 patients, representing 76% of the initial cohort. Clinical and social outcomes were significantly better for patients in Agra and Ibadan than for those in the centres in developed countries. In Cali, only social outcome was significantly better.

Problems of transformation.

Despite the progressive reduction over many years in patient populations of psychiatric hospitals in America and many European countries, there have been few attempts to evaluate this policy. The Team for the Assessment of Psychiatric Services (TAPS) was established to monitor and evaluate the closure of two large psychiatric hospitals in North London. A number of important problems have been identified in the course of the TAPS research programme. These include: the inertia of the planning process, the selection of the best patients first for discharge at the expense of the more disabled, the accumulation of new long-stay patients entering the admission wards of psychiatric hospitals, the policy of introducing patients into the community as unobtrusively as possible, and the difficulties of deinstitutionalising staff. Despite these problems, evidence is presented that discharge of long-stay patients into the community has been relatively successful.

The perception of emotion by schizophrenic patients.

Studies which have examined the perception of emotion by schizophrenic patients have produced conflicting results, an outcome which may, in part, be due to difficulties in presenting a realistic portrayal of emotion. This study exposed 32 schizophrenic patients in remission and ten controls to five videotaped scenes of emotional situations played by actors. The schizophrenic patients were divided into three groups, namely those living with high-EE relatives, those living with low-EE relatives and those living alone, in order to test the hypothesis that patients in a high-EE environment are less able to identify emotionally charged situations. Measures of electrodermal activity and self-ratings of tension were recorded concomitantly. The schizophrenic patients in all groups were as adept at identifying emotions as were the controls. There was no difference between the groups in electrodermal activity and subjective tension for all video scenes, except for the one which portrayed the only pleasant interaction; the high-EE group was significantly more aroused on both measures, which were independent of each other.

Schizophrenia in the melting pot.

The puzzle of schizophrenia has been approached from many directions. But, despite the development of molecular genetic techniques, the origin of the condition remains obscure.

Family therapy outcome research: a trial for families, therapists, and researchers.

This article describes the process of an evolving research project. Initially conceived as a study investigating outcome measures and their sensitivity to change after a course of family therapy, the project soon changed its focus. As unexpected results were recorded, the clinical research team became destabilized and the individual team members responded by making their own "sense" of the data, reflecting their respective clinical and scientific positions. As clinicians and researchers began to challenge each other's belief systems, the project entered a new stage. The interactions within the team became of increasing interest and themselves objects of research. The recursive nature of re-search was demonstrated, and the act of writing this report completed the circle, as the various authors tried to achieve a balance between reporting the content and the process of this project.

Relatives' expressed emotion and the course of schizophrenia in Chandigarh. A two-year follow-up of a first-contact sample.

A two-year follow-up was conducted of a subsample of the Chandigarh cohort of first-contact schizophrenic patients from the WHO Determinants of Outcome project. The patients were those living with family members who had been interviewed initially to determine their levels of expressed emotion (EE). The interview was repeated for 74% of the relatives at one-year follow-up. A dramatic reduction had occurred in each of the EE components and in the global index. No rural relative was rated as high EE at follow-up. Of the patients included in the one-year follow-up, 86% were followed for two years. In contrast to the one-year findings, the global EE index at initial interview did not predict relapse of schizophrenia over the subsequent two years. However, there was a significant association between initial hostility and subsequent relapse. The better outcome of this cohort of schizophrenic patients compared with samples from the West is partly attributable to tolerance and acceptance by family members.

A trial of family therapy versus a relatives' group for schizophrenia. Two-year follow-up.

The results are reported of a two-year follow-up of a trial of family sessions in the home (including patients) (12 families) versus a relatives' group (excluding patients) (11 families). Subjects were patients with schizophrenia living in high face-to-face contact with high-EE relatives. Patients were maintained on neuroleptic drugs for two years where possible. Relatives' critical comments and hostility were significantly lowered by nine months, but no significant changes occurred subsequently. Relatives' overinvolvement reduced steadily throughout the trial, and reduction in relatives' EE, either alone or in combination with reduced face-to-face contact, appeared to be associated with a lower relapse rate. The relapse rates for patients in the family-therapy and relatives'-group streams were 33% and 36% at two years. When these data were combined with the results of a previous trial, it was found that patients in families assigned to any form of social intervention had a two-year relapse rate of 40%, significantly lower than the 75% relapse rate for patients whose families were offered no help. We therefore recommend that relatives' groups are established in conjunction with some family sessions in the home for patients at high risk of relapse.

The TAPS project. 3: Predicting the community costs of closing psychiatric hospitals.

The planning of long-term care in the community as an alternative to in-patient care requires accurate information on the likely expense of altering the balance of provision. Unfortunately, as very few long-stay psychiatric hospitals have yet closed, the planning of these resource requirements has had to proceed in a vacuum. By examining the costs of community reprovision for the first 136 people to leave Claybury and Friern Hospitals, a prediction equation has been estimated from existing data which links the hospital-assessed characteristics (including psychiatric symptoms and behavioural problems) of these people to the subsequent cost of community care. About a third of the observed variation in these costs can be explained statistically by these 'baseline' characteristics. However, the first cohorts exhibit fewer behavioural problems and other symptoms of mental illness, they have been in hospital for shorter lengths of time, and they are younger. The prediction equation for the leavers is thus used to extrapolate community costs for those hospital residents yet to leave. It is found that community costs are lower than hospital costs, not just for the first cohorts of leavers, but for the full populations of the two hospitals scheduled to close.

The TAPS Project. 4: An observational study of the social life of long-stay patients.

Observations of long-stay patients in a club in a psychiatric hospital were carried out unobtrusively over several months. Much of the social activity that went on was stimulated by an economy based around the purchase and exchange of tea and cigarettes, and the borrowing and lending of small change. Most patients could be fitted into one of four social categories: helpers, friends, nuisances, and the asocial. The inter-rater reliability of the observations was found to be 0.95. A close correspondence emerged between the observations of patients' social behaviour and material reported by patients when interviewed with the Social Network Schedule.

The TAPS Project. 5: The structure of social-network data obtained from long-stay patients.

The Social Network Schedule was successfully completed on 489 (64%) of 770 long-stay patients in Friern and Claybury Hospitals and the data on 3774 social contacts of the patients subjected to log-linear modelling. This showed that the category 'confidant' was salient in understanding the data. Latent-class analysis highlighted the importance of the nature of the social interaction between patients and their contacts. In particular, non-verbal exchanges of goods and services emerged as important in creating social bonds.

A trial of family therapy v. a relatives group for schizophrenia.

Schizophrenic patients living in high contact with relatives having high expressed emotion (EE) were recruited for a trial of social interventions. The patients were maintained on neuroleptic medication, while their families were randomly assigned to education plus family therapy or education plus a relatives group. Eleven out of 12 families accepted family therapy in the home, whereas only six out of 11 families were compliant with the relatives group. Non-compliance was associated with a poorer outcome for the patients in terms of the relapse rate. The relapse rate over nine months in the family therapy stream was 8%, while that in compliant families in the relatives group stream was 17%. Patients' social functioning showed small, non-significant, gains. The data from the current trial were compared with data from a previous trial. The lowering of the relapse rate in schizophrenia appears to be mediated by reductions in relatives' EE and/or face-to-face contact, and is not explained by better compliance with medication. Reduction in EE and/or contact was associated with a minuscule relapse rate (5%). Very little change occurred in families who were non-compliant with the relatives group. On the basis of these findings, we recommend that the most cost-effective procedure is to establish relatives groups in conjunction with family education and one or more initial family therapy sessions in the home. It is particularly important to offer home visits to families who are unable to or refuse to attend the relatives groups.
