In a Dutch treatment intervention study of patients (n=76) with first psychotic episodes of schizophrenia the hypothesis tested was whether early differential treatment after an acute psychotic break improved outcome as compared with other studies. Patients had a relatively short duration of untreated psychosis. No significant effect between two treatment conditions on relapse rate was found. The 15-month intervention program kept the psychotic relapse rate as low as 15%; lower than comparable studies. Thus, the initial results were in support of the hypothesis. After completion of the 15 months study, patients were referred to other agencies and followed for five years. Results of the follow up study showed that the low relapse rate could not be maintained. Of the remaining 71 patients of the initial sample, 52% had one or more psychotic relapses, 25% developed chronic positive symptoms and 23% did not have another psychotic episode. In addition, the level of social functioning turned out to be low: the majority of patients were dependent upon their parents, few held down a skilled or paid job and also their quality of life seemed low, results indicate that early intervention may improve short term but not long term outcome in schizophrenia. Our results also suggest that referral to other mental health agencies after intervention is not sufficient. Continuity of outpatient care, including continuity of a professional relationship, continuity of support for the family, and the continuity in management of illness, medication and stress may be a key issue in the first five years after the onset of psychosis in schizophrenia. Early recognition and intervention may not nearly be as important for outcome as continuity in care and caregivers. At present, however, it remains questionable whether early intervention programs in first-episode patients with a short duration of untreated psychosis can offer the prospect of altering the course of schizophrenia without a sustained comprehensive treatment program. Little is known about the medium-term durability of cognitive-behavioural therapy (CBT) in a community sample of people with schizophrenia.
                To investigate whether brief CBT produces clinically important outcomes in relation to recovery, symptom burden and readmission to hospital in people with schizophrenia at 1-year follow-up.
                Participants (336 of 422 randomised at baseline) were followed up at a mean of 388 days (s.d. = 53) by raters masked to treatment allocation (CBT or usual care).
                At 1-year follow-up, participants who received CBT had significantly more insight (P = 0.021) and significantly fewer negative symptoms (P = 0.002). Brief therapy protected against depression with improving insight and against relapse; significantly reduced time spent in hospital for those who did relapse and delayed time to admission. It did not improve psychotic symptoms or occupational recovery, nor have a lasting effect on overall symptoms or depression at follow-up.
                Mental health nurses should be trained in brief CBT for schizophrenia to supplement case management, family interventions and expert therapy for treatment resistance. The paper describes a randomized controlled trial of targeting cognitive behavioural therapy (CBT) during prodromal or early signs of relapse in schizophrenia. We hypothesized that CBT would result in reduced admission and relapse, reduced positive and negative symptoms, and improved social functioning.
                A total of 144 participants with schizophrenia or a related disorder were randomized to receive either treatment as usual (TAU) (N = 72) or CBT+TAU (N = 72). Participants were prospectively followed up between entry and 12 months.
                At 12 months, 11 (15.3%) participants in the CBT group were admitted to hospital compared to 19 (26.4%) of the TAU group (hazard ratio = 0.53, P = 0.10, 95% CI 0.25, 1.10). A total of 13 (18.1%) participants in CBT relapsed compared to 25 (34.7%) in TAU (hazard ratio = 0.47, P < 0O05, 95% CI 0.24, 0.92). In addition, the CBT group showed significantly greater improvement in positive symptoms, negative symptoms, global psychopathology, performance of independent functions and prosocial activities.
                The study provides evidence for the feasibility and effectiveness for targeting CBT on the appearance of early signs of relapse in schizophrenia. The results are discussed in context of the study's methodological limitations. Carers' satisfaction with psychiatric services related to information and advice is generally poor. This may be particularly true for services trying to meet the needs of ethnically diverse communities. It is important that services attempt to ameliorate carers' concerns as early as possible. The authors aimed to assess the impact of a brief educational and advice support service on carers of patients with a first episode of psychotic illness.
                Carers of all patients identified with a first episode of psychosis in a defined psychiatric catchment area of North London were invited to participate. Following consent from patients and relatives, relatives were randomly allocated to receive (in addition to usual services) a brief intervention comprising education and advice about the disorder from a support team or to usual care from community psychiatric services.
                One hundred and six carers were recruited to the study. Take-up of the intervention was less than expected and the intervention had little impact. The authors found no differences over time between the randomized arms for relatives' satisfaction (F = 23, p = 0 .4, df = 1) or number of days spent by patients in hospital over nine months from entry to the trial (F= 1.7, p= 0.18, df = 1).
                It was found that the support and advice intervention for families had little impact on their satisfaction or on patients' outcomes. However, failure to take up the intervention threatens the conclusions as the power to show an effect was reduced. Although family interventions, in general, are considered an important adjunct to the treatment of patients with chronic psychosis, there may be difficulties in providing an educational and support intervention shortly after first onset. How and when psychiatric services provide information and advice to carers of people newly diagnosed with a psychosis requires further study. Family psychoeducation has a well-documented effect on the short-term prognosis in schizophrenia. Less is known about the effectiveness of shorter programmes with the main focus on information for patients (patient education) or for patients and relatives (family education).
                A randomized study of the effectiveness of an eight-session psychoeducational programme for patients with schizophrenia and for their relatives was conducted in two community mental health centres, in Arhus and Viborg (Denmark). Patient outcome measures were knowledge, relapse, compliance, insight and satisfaction, and relative outcome measures were knowledge and satisfaction. Post-intervention outcome and follow-up evaluation 1 year after the start of the intervention are presented.
                A statistically significant increase in knowledge of schizophrenia in both relatives and patients was demonstrated at postintervention and a non-significant trend at 1-year follow-up. Statistically significant changes in the Verona Service Satisfaction Scale Scores in the subdimension of satisfaction with Relatives involvement were demonstrated both for patients and relatives postintervention and for patients at 1-year follow-up. There was a tendency that time-to-relapse increased in the intervention group at postintervention and that the schizophrenia subscore of the Brief Psychiatric Rating Scale was reduced in the intervention group at 1-year follow-up. No differences were found between the groups regarding compliance, insight into psychosis, psychosocial function (General Assessment of Function) or in relatives' expressed emotion scores postintervention or at 1-year follow-up.
                A short patient and relative education programme seems to be able to influence knowledge and some aspects of satisfaction, but does not seem to be sufficient to influence important variables such as relapse, compliance, psychopathology, insight or psychosocial functioning. Family intervention reduces relapse rates in psychosis. Cognitive-behavioural therapy (CBT) improves positive symptoms but effects on relapse rates are not established.
                To test the effectiveness of CBT and family intervention in reducing relapse, and in improving symptoms and functioning in patients who had recently relapsed with non-affective psychosis.
                A multicentre randomised controlled trial (ISRCTN83557988) with two pathways: those without carers were allocated to treatment as usual or CBT plus treatment as usual, those with carers to treatment as usual, CBT plus treatment as usual or family intervention plus treatment as usual. The CBT and family intervention were focused on relapse prevention for 20 sessions over 9 months.
                A total of 301 patients and 83 carers participated. Primary outcome data were available on 96% of the total sample. The CBT and family intervention had no effects on rates of remission and relapse or on days in hospital at 12 or 24 months. For secondary outcomes, CBT showed a beneficial effect on depression at 24 months and there were no effects for family intervention. In people with carers, CBT significantly improved delusional distress and social functioning. Therapy did not change key psychological processes.
                Generic CBT for psychosis is not indicated for routine relapse prevention in people recovering from a recent relapse of psychosis and should currently be reserved for those with distressing medication-unresponsive positive symptoms. Any CBT targeted at this acute population requires development. The lack of effect of family intervention on relapse may be attributable to the low overall relapse rate in those with carers. The Early Detection and Intervention Programme of the German Research Network on Schizophrenia (GRNS) investigates the initial prodromal phase of psychosis in a multidimensional approach. Two intervention strategies are being studied by two large-scale multicentre projects.
                To present the concept of the intervention studies, and to provide an interim report of the recruitment procedure.
                Comprehensive cognitive-behavioural therapy has been developed for patients in the "early initial prodromal state". For patients in the "late initial prodromal state" the atypical neuroleptic amisulpride is explored. Both interventions are evaluated in randomised controlled trials using clinical management as the control condition.
                Between January 2001 and March 2003, 1212 individuals seeking help for mental health problems were screened for putative prodromal symptoms at four university centres. More than 388 individuals fulfilled criteria for both interventions and 188 (48.5%) gave informed consent to participate in the trials.
                The screening procedure appears to be feasible and trial participation seems to be acceptable to a relevant proportion of people at increased risk of developing psychosis. Schizophrenic patients were recruited into a trial of a prophylactic behavioural intervention with families. Families with at least one high Expressed Emotion (EE) relative were randomly allocated to one of four intervention groups: Behavioural Intervention Enactive; Behavioural Intervention Symbolic; Education Only; Routine Treatment. Patients from low-EE families were randomly allocated to two groups: Education Only or Routine Treatment. Relapse rates over nine months after discharge were significantly lower for patients in the two Behavioural Intervention, compared with Education Only and Routine Treatment groups. There was little difference between the two low-EE groups. Patients returning to high-EE relatives showed significantly higher relapse rates than those returning to low-EE relatives, in groups not receiving active intervention. Changes from high to low EE occurred in the Behavioural Intervention groups, and similar although less extensive changes occurred in the Education Only and Routine Treatment groups. Changes in criticism and marked emotional over-involvement (EOI) occurred generally in high-EE groups but were larger in magnitude in the Enactive and Symbolic groups. Reduction of hostility only occurred in the Behavioural Intervention groups. These results give partial support for the causal role of EE in relapse. There were no significant differences between the groups with respect to contact with the psychiatric services or medication. Recent research indicates that early detection of young persons suffering from psychosis and subsequent intensive intervention enhances treatment response and prognosis, but the data are only preliminary and suggestive.
                We present the rationale and design of the largest study to date to evaluate two major issues in the field of secondary prevention: (1) Does education and intensified collaboration with general practice, social services etc. reduce the duration of untreated psychosis? and (2) Can modified assertive community treatment improve the course and outcome in young persons suffering from psychosis as compared to treatment in community mental health centres? The article aims additionally to put the study in context and assist in designing future studies.
                Preliminary experiences are described. The findings of the first 312 patients show that modified assertive community treatment results in patients adhering to treatment significantly better than standard treatment in community mental health centres.
                The surge of interest in preventively oriented detection and treatment models for untreated psychosis in young people calls for research programmes and evidence. The obstacles to this are manifold. The initial findings of the OPUS study suggest, however, that better adherence to treatment is possible.
This review indicates that early warning signs interventions may have a positive effect on the proportions of people re-hospitalised and on rates of relapse, but not on time to recurrence. However, the overall quality of the evidence was very low, indicating that we do not know if early warning signs interventions will have similar effects outside trials and that it is very likely that further research will alter these estimates. Moreover, the early warning signs interventions were used along side other psychological interventions, and we do not know if they would be effective on their own. They may be cost-effective due to reduced hospitalisation and relapse rates, but before mental health services consider routinely providing psychological interventions involving the early recognition and prompt management of early warning signs to adults with schizophrenia, further research is required to provide evidence of high or moderate quality regarding the efficacy of early warning signs interventions added to usual care without additional psychological interventions, or to clarify the kinds of additional psychological interventions that might aid its efficacy. Future RCTs should be adequately-powered, and designed to minimise the risk of bias and be transparently reported. They should also systematically evaluate resource costs and resource use, alongside efficacy outcomes and other outcomes that are important to people with serious mental illness and their carers.
