Abstract
BACKGROUND Health anxiety is an under-recognised but a frequent cause of distress. It is particularly common in general hospitals. METHODS We carried out an 8-year follow-up of medical out-patients with health anxiety (hypochondriasis) enrolled in a randomised-controlled trial in five general hospitals in London, Middlesex and Nottinghamshire. Randomisation was to a mean of six sessions of cognitive behaviour therapy adapted for health anxiety (CBT-HA) or to standard care in the clinics. The primary outcome was a change in score on the Short Health Anxiety Inventory, with generalised anxiety and depression as secondary outcomes. Of 444 patients aged 16-75 years seen in cardiology, endocrinology, gastroenterology, neurology and respiratory medicine clinics, 306 (68.9%) were followed-up 8 years after randomisation, including 36 who had died. The study is registered with controlled-trials.com, ISRCTN14565822. RESULTS There was a significant difference in the HAI score in favour of CBT-HA over standard care after 8 years [1.83, 95% confidence interval (CI) 0.25-3.40, p = 0.023], between group differences in generalised anxiety were less (0.54, 95% CI -0.29 to 1.36), p = 0.20, ns), but those for depression were greater at 8 years (1.22, 95% CI 0.42-2.01, p < 0.003) in CBT-HA than in standard care, most in standard care satisfying the criteria for clinical depression. Those seen by nurse therapists and in cardiology and gastrointestinal clinics achieved the greatest gains with CBT-HA, with greater improvement in both symptoms and social function. CONCLUSIONS CBT-HA is a highly long-term effective treatment for pathological health anxiety with long-term benefits. Standard care for health anxiety in medical clinics promotes depression. Nurse therapists are effective practitioners.

Abstract
The effects of establishing a full multidisciplinary community psychiatric team in central London are described. The nature of referrals, and referrers' satisfaction with the service were examined during two comparable six-month periods, before and after the changes. The number and severity of referrals increased, and referrers were more satisfied with the new service. In contrast to the inter-agency model, the new multidisciplinary team was associated with more appropriate referral of those patients with the greatest need for specialist services. Clinical skill mix in the team and referrer education are the two factors most likely to have promoted these important changes. The key role of the psychiatrist in a full multidisciplinary team who can empower multi-professional case managers in their day-to-day management of severely ill patients is highlighted.

Abstract
Aims and methodTo compare an existing crisis resolution service with a new crisis resolution team (CRT) in Wales. The impact of the new team was measured by changes in bed days and admissions. A random sample of patients from each service was assessed for service satisfaction, social functioning and quality of life after first presentation.ResultsThe total number of bed days was reduced following the introduction of the new CRT (27.3%). The frequency and duration of compulsory admissions increased by 31% in the CRT between the first and second years and by 7% in the control service, offset by a greater reduction in informal admissions in the CRT (23.5%) compared with the control group (13.3%); overall bed usage was unchanged. Service satisfaction, social functioning and quality of life showed no important differences between the services.Clinical implicationsCrisis resolution teams may reduce informal admissions in the short term but at the cost of more compulsory admissions later.

Abstract
BACKGROUND Aggressive challenging behaviour is very common in care homes for people with intellectual disability, and better psychological treatments are needed. Nidotherapy aims to change the environment of people with mental illness and is an appropriate treatment for this group of disorders. METHOD The design was a cluster randomised trial of 20 care homes in which the staff either received training in nidotherapy or the enhanced care programme approach (ECPA), with equivalent duration of treatment in each arm. Cluster randomisation of care homes was carried out at the beginning of the study by an independent statistician. Primary and secondary outcomes were not specified exactly in view of absence of previous study data, but changes over time in scores on two scales, the Modified Overt Aggression Scale and the Problem Behaviour Check List were the main outcome measures. Serious violent incidents were recorded using the Quantification of Violence Scale. All these measures were recorded monthly by research assistants who were carefully kept blind to the allocation of treatment. RESULTS A total of 200 residents entered the trial, 115 allocated to the ECPA arm and 85 to the nidotherapy one. Seven residents left the care homes in the course of the study, and six were replaced; these were included 79 in the analysis as the trial was a pragmatic one. There were no material reductions in challenging behaviour in the first 8 months of the trial in either group, but in the last 7 months, those allocated to nidotherapy had a 33% reduction in Modified Overt Aggression Scale (MOAS) scores and a 43% reduction in Problem Behaviour Check List scores compared with 5% and 13%, respectively, for the ECPA group, differences which for the MOAS were close to statistical significance. DISCUSSION Nidotherapy shows promise in the management of aggressive challenging behaviour in care homes, but a delay in its benefit might be expected if given to staff only. The treatment is worthy of further evaluation and development.

Abstract
A comparison of the prevalence of health anxiety in genitourinary medicine (GUM) clinics in two UK centres was carried out using a new rating scale, the Health Anxiety Inventory (HAI). The relationship of health anxiety to demographic and clinical variables, and its impact on service contacts, was also examined in one of these centres. 694 patients were assessed and significant health anxiety was identified in 8–11%. HAI scores were stable over time and high levels persisted in the absence of treatment. Attenders with sexually transmitted infections had significantly lower levels of health anxiety than those with other conditions. Contacts with clinic doctors and health advisors in the nine months before and after assessment were significantly greater in those with high health anxiety, with doctor appointments 37% higher in the high HAI group ( P = 0.005). Health anxiety is a source of considerable morbidity in GUM clinics deserving further study.

Abstract
BACKGROUND Both the classification of personality disorder in intellectual disability (ID) and its identification in practice are deemed to be difficult. A simpler approach to classification and its relationship to challenging behaviours were tested in an adult Jamaican population with ID. METHOD The study was carried out in Kingston, Jamaica, as part of a programme of field trials to determine the utility of the proposed revision of personality disorders in the 11th Revision of the International Classification of Diseases (ICD-11), in a population of adults with ID living with their families or in supported care homes. Thirty-eight people with borderline (n = 5), mild (n = 16), moderate (n = 14) and severe (n = 3) ID were assessed at face-to-face interview and with relatives or staff using the provisional criteria for severity of personality disorder and its associated domain traits, and challenging behaviour was assessed using the Problem Behaviour Check List (PBCL) (a 5-point, 7-item scale). RESULTS Using the severity scale 18 patients (47%) had no personality disorder, 7 (18%) had personality difficulty, 9 (24%) had mild personality disorder, and 4 (11%) had moderate personality disorder. None of the sample had severe personality disorder in which there is high risk of harm to self or others. Of the four major trait domains, provisionally named anankastic, detached, emotional and dissocial, three were evenly distributed in those with personality disturbance with the antagonistic (antisocial) trait less commonly shown (6 only). Scores on the PBCL were higher in those with increasing severity of personality disorder (P = 0.03) and those in the antagonistic personality trait domain had the highest PCL scores. CONCLUSIONS Despite previous difficulties in assessing personality disorder in intellectual difficulties the ICD-11 classification was easy to administer in practice in this population, and the higher problem behaviour scores in those with greater severity of personality disturbance support its construct validity.

Abstract
BACKGROUND There has been major concern about the 'over-representation' of Black and ethnic minority groups amongst people detained under the Mental Health Act (MHA). We explored the effect of patient ethnicity on detention following an MHA assessment, once confounding variables were controlled for. METHOD Prospective data were collected for all MHA assessments over 4-month periods in the years 2008, 2009, 2010 and 2011 each in three regions in England: Birmingham, West London and Oxfordshire. Logistic regression modelling was conducted to predict the outcome of MHA assessments - either resulting in 'detention' or 'no detention'. RESULTS Of the 4423 MHA assessments, 2841 (66%) resulted in a detention. A diagnosis of psychosis, the presence of risk, female gender, level of social support and London as the site of assessment predicted detention under the MHA. Ethnicity was not an independent predictor of detention. CONCLUSIONS There is no evidence for that amongst those assessed under the MHA, ethnicity has an independent effect on the odds of being detained.

Abstract
OBJECTIVE Clinicians often consider whether or not offenders with psychosis have a history of offending pre-dating the onset of their illness. The typology of offenders based on age at first offence, developed in the field of criminology, has been recently extended to mentally disordered groups, but this ignores the potential role of illness onset. METHOD Using a large UK cohort of individuals with both psychosis and offending histories (n=331), we compared those with a history of offending pre-dating their illness (pre-morbid offenders) to those who commenced offending after becoming unwell (post-morbid offenders). We compared the demographic, clinical and offending pattern characteristics of the two groups. RESULTS 198 (60%) had offended before the onset of psychosis. These pre-morbid offenders were more likely to be male, have a lower pre-morbid IQ and have had a history of neurological abnormality. Pre-morbid offenders also committed more crime overall, but this was due to an excess of acquisitive, drug and minor offending, rather than violent offending, which was comparable to the post-morbid offending group. CONCLUSION Currently, standardised clinical risk assessment tools view offenders with mental illness as a homogenous group with respect to life-course patterns of offending in relation to illness. Taking account of an individual's pathway to offending may improve risk assessment and management.

Abstract
OBJECTIVE To examine the clinical effectiveness and cost-effectiveness of referral to group art therapy plus standard care, compared with referral to an activity group plus standard care and standard care alone, among people with schizophrenia. DESIGN A three-arm, parallel group, single-blind, pragmatic, randomised controlled trial. Participants were randomised via an independent and remote telephone randomisation service using permuted blocks, stratified by study centre. SETTING Study participants were recruited from secondary care mental health and social services in four UK centres. PARTICIPANTS Potential participants were aged 18 years or over, had a clinical diagnosis of schizophrenia, confirmed by an examination of case notes, and provided written informed consent. We excluded those who were unable to speak sufficient English to complete the baseline assessment, those with severe cognitive impairment and those already receiving arts therapy. INTERVENTIONS Group art therapy was delivered by registered art therapists according to nationally agreed standards. Groups had up to eight members, lasted for 90 minutes and ran for 12 months. Members were given access to a range of art materials and encouraged to use these to express themselves freely. Activity groups were designed to control for the non-specific effects of group art therapy. Group facilitators offered various activities and encouraged participants to collectively select those they wanted to pursue. Standard care involved follow-up from secondary care mental health services and the option of referral to other services, except arts therapies, as required. MAIN OUTCOME MEASURES Our co-primary outcomes were global functioning (measured using the Global Assessment of Functioning Scale - GAF) and mental health symptoms (measured using the Positive and Negative Syndrome Scale - PANSS) at 24 months. The main secondary outcomes were level of group attendance, social functioning, well-being, health-related quality of life, service utilisation and other costs measured 12 and 24 months after randomisation. RESULTS Four hundred and seventeen people were recruited, of whom 355 (85%) were followed up at 2 years. Eighty-six (61%) of those randomised to art therapy and 73 (52%) of those randomised to activity groups attended at least one group. No differences in primary outcomes were found between the three study arms. The adjusted mean difference between art therapy and standard care at 24 months was -0.9 [95% confidence interval (CI) -3.8 to 2.1] on the GAF Scale and 0.7 (95% CI -3.1 to 4.6) on the PANSS Scale. Differences in secondary outcomes were not found, except that those referred to an activity group had fewer positive symptoms of schizophrenia at 24 months than those randomised to art therapy. Secondary analysis indicated that attendance at art therapy groups was not associated with improvements in global functioning or mental health. Although the total cost of the art therapy group was lower than the cost of the two comparison groups, referral to group art therapy did not appear to provide a cost-effective use of resources. CONCLUSIONS Referring people with established schizophrenia to group art therapy as delivered in this randomised trial does not appear to improve global functioning or mental health of patients or provide a more cost-effective use of resources than standard care alone.

Abstract
OBJECTIVE To investigate the relationship between science production and the indexation level of low- and middle-income countries (LAMIC) journals in international databases. METHOD Indicators of productivity in research were based on the number of articles produced over the 1994-2004 period. A survey in both Medline and ISI/Thomson was conducted to identify journals according to their country of origin. A WPA Task Force designed a collaborative process to assess distribution and quality of non-indexed LAMIC journals. RESULTS Twenty LAMIC were found to present more than 100 publications and a total of 222 indexed psychiatric journals were found, but only nine were from LAMIC. The Task Force received 26 questionnaires from editors of non-indexed journals, and concluded that five journals would meet criteria for indexation. CONCLUSION Barriers to indexation of journals contribute to the difficulties in achieving fair representation in the main literature databases for the scientific production in these countries.

Abstract
BACKGROUND Aggressive challenging behaviour in people with intellectual disability (ID) is frequently treated with antipsychotic drugs, despite a limited evidence base. METHOD A multi-centre randomised controlled trial was undertaken to investigate the efficacy, adverse effects and costs of two commonly prescribed antipsychotic drugs (risperidone and haloperidol) and placebo. RESULTS The trial faced significant problems in recruitment. The intent was to recruit 120 patients over 2 years in three centres and to use a validated aggression scale (Modified Overt Aggression Scale) score as the primary outcome. Despite doubling the period of recruitment, only 86 patients were ultimately recruited. CONCLUSIONS Variation in beliefs over the efficacy of drug treatment, difficulties within multidisciplinary teams and perceived ethical concerns over medication trials in this population all contributed to poor recruitment. Where appropriate to the research question cluster randomised trials represent an ethically and logistically feasible alternative to individually randomised trials.

Abstract
OBJECTIVE(S) To assess the effects and cost-effectiveness of haloperidol, risperidone and placebo on aggressive challenging behaviour in adults with intellectual disability. DESIGN A double-blind randomised controlled trial of two drugs and placebo administered in flexible dosage, with full, independent assessments of aggressive and aberrant behaviour, global improvement, carer burden, quality of life and adverse drug effects at baseline, 4, 12 and 26 weeks, and comparison of total care costs in the 6 months before and after randomisation. At 12 weeks, patients were given the option of leaving the trial or continuing until 26 weeks. Assessments of observed aggression were also carried out with key workers at weekly intervals throughout the trial. SETTING Patients were recruited from all those being treated by intellectual disability services in eight sites in England, one in Wales and one in Queensland, Australia. PARTICIPANTS Patients from all severity levels of intellectual disability; recruitment was extended to include those who may have been treated with neuroleptic drugs in the past. EXCLUSION CRITERIA treatment with depot neuroleptics/another form of injected neuroleptic medication within the last 3 months; continuous oral neuroleptic medication within the last week; those under a section of the Mental Health Act 1983 or Queensland Mental Health Act 2000. INTERVENTIONS Randomisation to treatment with haloperidol (a typical neuroleptic drug), risperidone (an atypical neuroleptic drug) or placebo using a permuted blocks procedure. Dosages were: haloperidol 1.25-5.0 mg daily; risperidone 0.5-2.0 mg daily. MAIN OUTCOME MEASURES Primary: reduction in aggressive episodes between baseline and 4 weeks using Modified Overt Aggression Scale. Secondary: Aberrant Behaviour Checklist; Uplift/Burden Scale; 40-item Quality of Life Questionnaire; Udvalg for Kliniske Undersøgelser scale; Clinical Global Impressions scale. Economic costs recorded using a modified version of Client Service Receipt Inventory for 6 months before and after randomisation. RESULTS There were considerable difficulties in recruitment because of ethical and consent doubts. Twenty-two clinicians recruited a total of 86 patients. Mean daily dosages were 1.07 mg rising to 1.78 mg for risperidone and 2.54 mg rising to 2.94 mg for haloperidol. Aggression declined dramatically with all three treatments by 4 weeks, with placebo showing the greatest reduction (79%, versus 57% for combined drugs) (p = 0.06). Placebo-treated patients showed no evidence of inferior response in comparison to patients receiving neuroleptic drugs. An additional study found that clinicians who had not participated in clinical trials before were less likely to recruit. Mean total cost of accommodation, services, informal care and treatment over the 6 months of the trial was 16,336 pounds for placebo, 17,626 pounds for haloperidol and 18,954 pounds for risperidone. CONCLUSIONS There were no significant important benefits conferred by treatment with risperidone or haloperidol, and treatment with these drugs was not cost-effective. While neuroleptic drugs may be of value in the treatment of aggressive behaviour in some patients with intellectual disability, the underlying pathology needs to be evaluated before these are given. The specific diagnostic indications for such treatment require further investigation. Prescription of low doses of neuroleptic drugs in intellectual disability on the grounds of greater responsiveness and greater liability to adverse effects also needs to be re-examined.

BACKGROUND Antipsychotic drugs are used in the routine treatment of adults with intellectual disabilities (ID) and challenging behaviour in the UK despite limited evidence of their effectiveness. There is no evidence on their cost-effectiveness. METHODS The relative cost-effectiveness of risperidone, haloperidol and placebo in treating individuals with an ID and challenging behaviour was compared from a societal perspective in a 26-week, double-blind, randomised controlled trial. Outcomes were changes in aggression and quality of life. Costs measured all service impacts and unpaid caregiver inputs. RESULTS After 26 weeks, patients randomised to placebo had lower costs compared with those in the risperidone and haloperidol treatment groups. Aggression was highest for patients treated with risperidone and lowest for patients treated with haloperidol; however, quality of life was lowest for patients treated with haloperidol and highest for patients treated with risperidone. CONCLUSION The treatment of challenging behaviour in ID with antipsychotic drugs is not a cost-effective option.

Abstract
BACKGROUND Little information exists on treatment effectiveness in antisocial personality disorder (ASPD). We investigated the feasibility and effectiveness of carrying out a randomized controlled trial of cognitive behaviour therapy (CBT) in men with ASPD who were aggressive. METHOD This was an exploratory two-centre, randomized controlled trial in a community setting. Fifty-two adult men with a diagnosis of ASPD, with acts of aggression in the 6 months prior to the study, were randomized to either treatment as usual (TAU) plus CBT, or usual treatment alone. Change over 12 months of follow-up was assessed in the occurrence of any act of aggression and also in terms of alcohol misuse, mental state, beliefs and social functioning. RESULTS The follow-up rate was 79%. At 12 months, both groups reported a decrease in the occurrence of any acts of verbal or physical aggression. Trends in the data, in favour of CBT, were noted for problematic drinking, social functioning and beliefs about others. CONCLUSIONS CBT did not improve outcomes more than usual treatment for men with ASPD who are aggressive and living in the community in this exploratory study. However, the data suggest that a larger study is required to fully assess the effectiveness of CBT in reducing aggression, alcohol misuse and improving social functioning and view of others. It is feasible to carry out a rigorous randomized controlled trial in this group.

Abstract
OBJECTIVE To quantify levels of engagement and retention in specialist services for people with personality disorder (PD). METHOD Demographic and clinical data were collected on referrals to 10 specialist services for people with PD. Follow-up data on retention and drop-out from services were collected over the following 30 months. RESULTS Seven hundred and thirteen (60.1%) of 1186 people referred to services were taken by them, of whom 164 (23.0%) subsequently dropped out prior to the completion of an episode of care. Men, younger people and those with higher levels of personality disturbance were less likely to complete a package of care. CONCLUSION Specialist community-based services for adults with PD are able to engage most of those that are referred to them, but further efforts need to be made to find ways to engage younger people and men with PD.

Abstract
The World Psychiatric Association (WPA) Task Force and a small group previously convened by the WPA publications committee initiated three activities between 2006-2008 that aimed to respond to the need for greater support for psychiatry journals in LAMI countries. In a joint venture with participants from the Global Mental Health Movement the Task Force editors from LAMI countries in Africa, Asia, Eastern Europe and Latin America were contacted to identify potential journals to target for indexation (Medline and ISI). The committee analyzed the editors' applications on the following criteria: a) geographical representativeness; b) affiliation to a professional mental health society; c) regular publication of at least 4 issues per year over the past few years; d) comprehensive national and international editorial boards; e) publication of original articles, or at least abstracts, in English; f) some level of current indexation; g) evidence of a good balance between original and review articles in publications; and h) a friendly access website. The committee received 26 applications (11 from Latin America, 7 from Central Europe, 4 from Asia and 4 from Africa), and selected 8 journals, 2 from each geographical area, on the basis of the overall scores obtained for the items mentioned, to participate in an editors meeting held in Prague in September 2008. The aims of the committee are twofold: a) to concentrate support for those selected journals; and b) to assist all LAMI mental health editors in improving the quality of their journals and fulfilling the requirements for full indexation. This report summarizes the procedures conducted by the committee, the assessment of the current non-indexed journals, and offers suggestions for further action.

Abstract
Closure of asylums and institutions for the mentally ill, coupled with government policies focusing on reducing the number of hospital beds for people with severe mental illness in favor of providing care in a variety of nonhospital settings, underpins the rationale behind care in the community. A major thrust toward community care has been the development of community mental health teams.

Abstract
BACKGROUND Personality disorder (PD) in psychosis is poorly studied. As PD can affect outcome in mental disorders, it is important to understand its prevalence in order to plan services, understand prognosis more fully and maximize management options. MethodLiterature searching revealed 3972 potential papers. Twenty papers including 6345 patients were included in the final analysis. There was great variation in prevalence and multilevel modelling was used to identify possible reasons for this heterogeneity. RESULTS The prevalence of PD varied from 4.5% to 100%. Multilevel analysis suggested country of study, study type, the instruments used to diagnose PD and patient care correlated with the prevalence data explaining the study level heterogeneity, with 34.2, 33.4, 17.0 and 4.5% by each variable respectively. Personality studies in Canada and Sweden reported lower PD prevalence, whereas in Spain it was higher than the multinational study. Compared with randomized controlled trials, case-control studies reported lower prevalence [odds ratio (OR)=0.35, 95% confidence interval (CI) 0.15-0.79] and observational studies higher prevalence (OR 70.5, 95% CI 8.5-583). Primary-care patients were less likely to be diagnosed (OR 0.02, 95% CI 0-0.19) than hospital patients, and out-patients had higher prevalence (OR 12.5, 95% CI 1.77-88.6). CONCLUSIONS The reported prevalence of PD in schizophrenia varies significantly. Statistical modelling suggests care, country, study type and diagnostic tools for PD all bias prevalence rates. The number of papers reaching the inclusion criteria, the relative paucity of information and the difficulties in developing an accurate statistical model limited interpretation from the study.

Abstract
OBJECTIVE The aim of this study was to establish the prevalence and predictors of violent victimization amongst a community-dwelling sample of individuals with psychosis. METHOD The 2-year prevalence of self-reported violent victimization was estimated for a sample of 708 individuals with chronic psychosis living in the community in four urban UK centres. Baseline socio-demographic and clinical factors were examined as possible risk factors for victimization over the 2-year follow-up period. RESULTS The 2-year prevalence of violent victimization in the sample was 23%. Four factors were found to be independently predictive of victimization - history of victimization, less than daily family contact, young age at illness onset and the presence of co-morbid Cluster B personality disorder. CONCLUSION Those with psychotic illnesses are at elevated risk of being assaulted. Given the likely adverse health implications, clinicians should routinely enquire about victimization in their assessments of those with psychotic disorders particularly amongst those who are socially isolated, with a younger age of illness onset and in those with co-morbid personality disorder.
