The magnetic resonance imaging studies investigating the volumes of the orbitofrontal cortex in patients suffering from schizophrenia are here presented, trying to elucidate its role for the pathophysiology and for the cognition of the disease.

Although the anatomy of the parietal lobe has been under-investigated in schizophrenia, some magnetic resonance imaging studies have shown decreased volumes, suggesting its possible implication for the pathophysiology of the disease.

Here we briefly summarize the most consistent structural MRI studies on hippocampus in major depression and debate the effects of clinical variables on hippocampal morphology.

Imaging studies have tried to identify morphological outcome measures of schizophrenia in the last two decades. In particular, longitudinal studies have reported a correlation between larger ventricles, decreased prefrontal volumes and worse outcome. This would potentially allow to isolate subtypes of schizophrenia patients with a worse prognosis and more evident biological impairments, ultimately helping in designing specific rehabilitation interventions.

This paper describes the process of preparing a Clinical Guideline for “NICE”, the National Institute for Health and Clinical Excellence in the United Kingdom. The procedure involves the group appointed to prepare the guideline relating to the various “stakeholders” who have an interest on the one hand, and satisfying the fairly demanding standards set by NICE on the other. The strengths and limitations of the approach based on evidence based medicine are discussed.

Aims — This study had two objectives: 1) to design and develop a computer-based tool, called Multi-Objective Evolutionary Algorithm/Hot-Spots (MOEA/HS), to identify and geographically locate highly autocorrelated zones or hot-spots and which merges different methods, and 2) to carry out a demonstration study in a geographical area where previous information about the distribution of schizophrenia prevalence is available and which can therefore be compared. Methods — Local Indicators of Spatial Aggregation (LISA) models as well as the Bayesian Conditional Autoregressive Model (CAR) were used as objectives in a multicriteria framework when highly autocorrelated zones (hot-spots) need to be identified and geographically located. A Multi-Objective Evolutionary Algorithm (MOEA) model was designed and used to identify highly autocorrelated areas of the prevalence of schizophrenia in Andalusia. Hot-spots were statistically identified using exponential-based QQ-Plots (statistics of extremes). Results — Efficient solutions (Pareto set) from MOEA/HS were analysed statistically and one main hot-spot was identified and spatially located. Our model can be used to identify and locate geographical hot-spots of schizophrenia prevalence in a large and complicated region. Conclusions — MOEA/HS enables a compromise to be achieved between different econometric methods by highlighting very special zones in complex areas where schizophrenia shows a high autocorrelation.

Aims – Impulsivity is a multifaceted aspect of behavior that is prominent in psychiatric disorders and has serious behavioral consequences. This paper reviews studies integrating behavioral and physiological mechanisms in impulsivity and their role in severity and course of bipolar and related disorders. Methods – This is a review of work that used questionnaire, human behavioral laboratory, and neurophysiological measurements of impulsivity or related aspects of behavior. Subjects included individuals with bipolar disorder, substance-use disorders, antisocial personality disorder, and healthy controls. Results – Models of impulsivity include rapid-response impulsivity, with inability to reflect or to evaluate a stimulus adequately before responding, and reward-based impulsivity, with inability to delay response for a reward. In normal subjects, rapid-response impulsivity is increased by yohimbine, which increases norepinephrine release. Impulsivity is increased in bipolar disorder, whether measured by questionnaire, by measures of rapid-response impulsivity, or by measures of ability to delay reward. While affective state has differential effects on impulsivity, impulsivity is increased in bipolar disorder regardless of affective state or treatment. Impulsivity, especially rapid-response, is more severe with a highly recurrent course of illness or with comorbid substance-use disorder, and with history of medically severe suicide attempt. In antisocial personality disorder, rapid-response impulsivity is increased, but rewardbased impulsivity is not. In general, impulsivity is increased more in bipolar disorder than in antisocial personality disorder. In combined bipolar disorder and antisocial personality disorder, increased impulsivity is associated with substance-use disorders and suicide attempts. Conclusions – Impulsivity is associated with severe behavioral complications of bipolar disorder, antisocial personality disorder, and substance-use disorders.

Aims – Based on findings from population surveys, we provide an overview of the public's emotional reactions to people with mental illness. Methods – A literature search for populations studies using measures of emotional response to people with mental illness was carried out. In addition, data on the public's emotional reactions, originating from representative surveys conducted in Germany in the years 1990, 1993 and 2001, were analysed. Results – Positive emotional reactions to people with mental illness are most prevalent, followed by fear and anger. This pattern appears relatively stable across different cultures. In recent years, the emotional response of the public remained unchanged or even deteriorated. The public seems to react quite differently to people with different mental disorders. Emotional reactions have a substantial effect on the desire for social distance. The association between familiarity with mental disorder and the desire for social distance is to a considerable extent mediated through emotions. Conclusions – The public's emotional reactions to people with mental disorder are relatively under-researched. More research may help better understand the complexities of the stigma surrounding mental illness. Interventions aimed at reducing the stigma of mental illness may benefit from paying more attention to emotions.

Aims — To describe patterns of experienced andanticipated discrimination in a sample of schizophrenic patients recruited in Italy in the context of the International Study of Discrimination and Stigma Outcomes (INDIGO). Methods — Cross-sectional survey on a sample of 50 people with clinical diagnosis of schizophrenia recruited in the Italian INDIGO sites of Verona and Brescia. The 41-item interview-based Discrimination and Stigma Scale (DISC-10), which assesses how experienced and anticipated discrimination affects the life of people with schizophrenia, was used. Results — The most frequently occurring areas of experienced discrimination were discrimination by family members (44%), making and keeping friends (33%), keeping (36%) and finding a job (34%), getting or keeping a driving licence (32%). Anticipated discrimination was common in applying for work, training or education (58%), lookingfor close relationships (50%) and doing something important (48%); 68% felt the need to conceal their diagnosis. Positive experiences were rare, and getting welfare benefits/disability pensions was the only area where participants reported being treated with advantage (34%) more commonly than with disadvantage (8%). Overall, experienced discrimination reported by Italian patients was in the intermediate position of the score range of all INDIGO sites, whereas anticipated discrimination was lower than that reported in the other countries. Conclusions — Interventions to reduce discrimination against people with schizophrenia may need to address both actual and anticipated discrimination. Targeted therapeutic strategies aiming to improve self-esteem of people with schizophrenia may be usefulto facilitate their social participation and full inclusion in the community.

Aims – The Diagnostic Interview for Psychoses (DIP) is a comprehensive interview schedule for psychotic disorders, linked to the OPCRIT diagnostic algorithm, bridging the gap between fully structured, lay-administered schedules and semistructured, psychiatrist-administered interviews. Here we describe the validity, reliability and applications of the Italian version of the DIP. Methods – The interview was translated into Italian and its content validity tested by back translation. Sixty patients, drawn from among those who contacted the South-Verona Community Mental Health Service, were included in the study. Each patient was first assessed independently by two raters, one of whom conducted the interview, while the other assumed the role of observer. Subsequently (median: 89 days), 44 of these patients were re-interviewed by a third rater, who made an independent assessment. Diagnostic validity was assessed in 18 cases, interviewed with the DIP and using the SCAN as ‘gold standard. Results – The mean duration of the interview was 37 minutes for the inter-rater interviews and 39 minutes for the retest interviews. Good to excellent inter-rater reliability was demonstrated for both ICD-10 and DSM-IV diagnoses, while in the test-retest reliability pairwise agreement was high for half of the items. Diagnostic validity was good, with twelve out of the 18 DIP-OPCRIT diagnoses (67%) matching the SCAN diagnosis. Conclusions – Overall, the results support the reliability and validity of the Italian translation of the DIP. The Italian version will be useful both in routine practice to establish standard reference diagnoses of psychosis and in the research field, where it can be used by academic researchers in clinical trials and epidemiological studies.

Aims – The relationship between eating disorders, attachment, personality traits and eating psychopathology remains unexplored. This study tested the mediating role of temperament and character between parental bonding and psy-chopathology in bulimic women. Methods – 154 bulimic subjects and 154 healthy controls were compared using Parental Bonding Instrument (PBI), Temperament and Character Inventory (TCI), Eating Disorder Inventory-2 (EDI-2), and Beck Depression Inventory (BDI). Multiple regression analysis tested the mediation of personality traits between parenting and eating psy-chopathology. Results – Bulimic subjects displayed low maternal and paternal care and low self-directedness, and high novelty seeking and eating psychopathology. Maternal care was negatively related to social insecurity, inadequacy and impulsiveness. Paternal care predicted novelty seeking, self-directedness, interoceptive awareness, impulsiveness, and asceticism. The mediation effect of self-directedness between paternal care and psychopathology was significant, not the one of novelty seeking. Conclusions – Parental care is lower in bulimic than in control women even when controlled for possible confounding variables. Some eating psychopathology traits are related to maternal and paternal care, but not the bulimia subscale. Paternal care is also related to temperament and character traits which are related to eating psychopathology. Self-directedness mediates with different degrees between parenting and eating psychopathology. Clinical implications are discussed.

Aims – This paper seeks to provide a methodology to assess the cost-effectiveness of anti-stigma campaigns for people with mental health problems. Methods – The costs of running a national campaign in Scotland were obtained and combined with the number of adults in the Scottish population and the estimated number of people with improved attitudes towards people with mental health problems. A decision model was constructed to estimate the economic impact of a campaign in terms of increased use of services by people with depression and increased work time. Results – If the campaign caused 10% of changed attitudes then it was estimated to cost £35 per one less person who felt that people with mental health problems were dangerous and £186 per one less person who felt the public needs protection from people with mental health problems. The decision model suggested extra economic benefits (employment gains minus service costs) as a result of an anti-stigma campaign compared to the absence of a campaign. Conclusions – Data on the economic impact of anti-stigma campaigns are scarce and evaluation is intrinsically difficult. We have demonstrated a method to conduct such analyses. The model proposed here should be tested further as data become available.

Aim – to provide a conceptual and practical analysis of the impacts of mental health diagnoses on consumers and to consider how service users might contribute to the new psychiatric classifications currently being drawn up. Methods – A search was carried out revealing a very sparse literature on this topic. Consultations with service users were conducted and the views of experts sought. Results – Diagnosis is important as it marks the formal status of psychiatric patient being conferred. Consumers react differently, and often, negatively to this. Stigma can follow from a diagnosis. The process of giving a diagnosis can range from one of negotiation and taking the person's strengths into account to the blunt allocation of an unwanted label. Consumers can be reduced to their diagnosis so it becomes their whole personhood and this can have an effect on their sense of self. However, consumers are not passive victims and have their own strategies for dealing with these issues. Conclusion – Consumers can use these experiences to make contributions to the new diagnostic classification systems and to future research.

Aim – Instruments to measure the process - the daily activities of home care workers - have received little attention and may impede research in refining the active ingredients, the clientele best served and continuous quality improvement. We developed a decade ago in Quebec, Canada, a new daily contact log (relevé quotidien des contacts or RQC) that has now reached in practice 1 million entries. Methods – Three features distinguish the RQC development, namely, practical ergonomics, a clear logic, and response categories easy to understand and retain. The instrument is filled following any 10-minute or more contact with or about the client, and covers the location, time and actors of the episode of care, and the nature of the intervention (crisis, representing, accompanying, discussing) in 10 areas (i.e. medication, daily living activities, housing, relationships, substance abuse, legal, etc.). Inter-rater agreement for each RQC response category and rater agreement with a criterion measure (coded vignettes) were evaluated. Results – Kappa coefficients and intra-class correlation coefficients yielded results ranging from at least moderate to generally substantial agreement for all 77 response categories. Conclusions – The new RQC may support international studies of the implementation and application of various forms of intensive home care, refining its indications, and serves as a clinical and managerial tool to ensure quality of the interventions.

People with mental illness face stigma and discrimination in a variety of settings which can have an economic impact. Aim – The aim of this paper was to identify literature on the economic impact of mental illness stigma. Methods – A systematic review of the literature identified 30 papers from 27 studies by searching electronic databases and hand searching reference lists. Results – Mental illness stigma/discrimination was found to impact negatively on employment, income, public views about resource allocation and healthcare costs. Conclusions – Stigma and discrimination regarding mental health problems lead to adverse economic effects for people with these conditions. Interventions that reduce stigma may therefore also be economically beneficial.

Aim – To investigate whether employers who have experience of hiring people with mental health problems differ significantly from those without such experience in terms of knowledge, attitudes and behaviours regarding mental health in the workplace, and the concerns which they report about employing people with mental health problems. We also examine whether non-workplace social contact is associated with the above variables. Methods – A telephone survey was conducted with a randomly selected sample of British employers. The sample included a similar number of human resource managers and managers/executive employees in other roles. Results – 502 employers took part. Having employed someone with a mental health problem was associated with closer non-workplace social contact. Those with experience of employing applicants with mental health problems had significant differences in knowledge (regarding the law), and behaviour (having a policy on hiring applicants with disabilities) but not in attitudes. Conclusions – Non-workplace social contact may be useful to consider in understanding hiring practices. The nature of social contact at work and possible lack of impact of this contact on employer attitudes and concerns warrants further study. Greater support is needed for employers to understand the law regarding mental health problems in the workplace.

Aim – Delinquency among adolescents and antecedent conduct disorder among children has been recognized as a growing public mental health problem in contemporary societies. The contribution of the neighbourhood environment to delinquent behaviour was examined in a cohort of Dutch adolescents (aged approximately 11 years at baseline; n=394). Methods – Multilevel regression analyses estimated associations between baseline neighbourhood socioeconomic status and social capital, and delinquent behaviour two years later controlling for individual-level variables. Results – A significant interaction effect was found between neighbourhood environment variables and gender in models of delinquency, indicating that associations between neighbourhood environment variables and delinquency were apparent, for the most part, in girls only. However, higher level of neighbourhood informal social control was associated with increased delinquency rates in boys. Conclusion – In girls there is a longitudinal association between neighbourhood characteristics and delinquency, suggesting complex gender differences in the way the wider social environment impacts on behavioural outcomes.

Aim – To identify whether financial or material incentives improve treatment adherence in people with severe mental illness. Method – A systematic review of studies published between 1950 and 2008 was conducted. EMBASE, MEDLINE, EBM, AMED and PsycINFO were searched. Studies were included if a financial or material incentive was offered and if the sample had a severe mental illness. Results – Fourteen articles were identified; three studies on adherence to psychiatric treatment and one on physical exercise. Ten articles used incentives for adherence to substance misuse treatment programmes. In all studies, financial incentives were associated with an increase in adherence; however the effect was not always maintained once the incentive was withdrawn. Conclusion – While existing research suggests that financial incentives may improve treatment adherence in severely mentally ill populations, very few studies focus on psychiatric treatment. Further research may address the long term effectiveness of incentives on adherence in this population.

Declaration of Interest: The authors on this paper were supported by funds from the Wellcome Trust. All authors worked on a Wellcome Trust funded qualitative focus group study exploring stakeholder views on offering patients financial incentives to adhere to antipsychotic medication. Priebe is also lead applicant on a National Institute of Health Research (England) (NIHR) awarded grant to conduct a clinical trial on the use of financial incentives to achieve maintenance antipsychotic medication adherence.

Aim – We aimed at developing a prioritized set of quality indicators for schizophrenia care to be used for continuous quality monitoring. They should be evidence-based and rely on routine data. Methods – A systematic literature search was performed to identify papers on validated quality indicators published between 1990 to April 2008 in MEDLINE, the Cochrane databases, EMBASE and PsycINFO. Databases of relevant national and international organizations were searched. Indicators were described with respect to meaningfulness, feasibility and actionability. A workshop with relevant stakeholders evaluated the measures through a structured consensus process. Results – We identified 78 indicators through literature search and selected 22 quality indicators. Furthermore, 12 structural and case-mix indicators were choosen. Only five quality indicators were rated “essential indicators” (priority 1), 14 were rated “additional first choice” (priority 2), and three were rated as “additional second choice” (priority 3). Only four indicators assessed outcome quality. In the majority of indicators the evidence base supporting the indicator recommendation was weak. None of the selected indicators was validated in experimental studies. Conclusions – Evidence and validation base played only a subordinate role for indicator prioritisation by stakeholders indicating that there are discrepancies between clinical questions and requirements in schizophrenia care and scientific research.

Aim – To review the literature on the efficacy of electroconvulsive therapy [ECT], with a particular focus on depression, its primary target group. Methods – PsycINFO, Medline, previous reviews and meta-analyses were searched in an attempt to identify all studies comparing ECT with simulated-ECT [SECT]. Results – These placebo controlled studies show minimal support for effectiveness with either depression or ‘schizophrenia’ during the course of treatment (i.e. only for some patients, on some measures, sometimes perceived only by psychiatrists but not by other raters), and no evidence, for either diagnostic group, of any benefits beyond the treatment period. There are no placebo-controlled studies evaluating the hypothesis that ECT prevents suicide, and no robust evidence from other kinds of studies to support the hypothesis. Conclusions – Given the strong evidence (summarised here) of persistent and, for some, permanent brain dysfunction, primarily evidenced in the form of retrograde and anterograde amnesia, and the evidence of a slight but significant increased risk of death, the cost-benefit analysis for ECT is so poor that its use cannot be scientifically justified.
