Abstract
BACKGROUND Suicide has been recognised as one of the major causes of premature death in psychosis. However, predicting suicidal behaviour (SB) is still challenging in the clinical setting and the association of neurocognition with SB in psychosis remains poorly understood. This study aimed to investigate the role of neurocognitive performance as predictor of SB. Also, we sought to explore differences in the evolution of clinical and neurocognitive functioning between participants with/without history of suicide attempts (SA) over follow-up period. METHODS The sample of the study is composed by 517 patients. Sociodemographic, clinical, functional and neurocognitive measures were evaluated at baseline as well as 1-year and 3 years after first episode of psychosis. Bivariate and multivariate analyses explored the influence of these variables as putative baseline predictors of SB. Repeated measures analyses of variance tested differences in clinical and neurocognitive outcomes at 1- and 3-year follow-up. RESULTS Global cognitive functioning (GCF) (OR = 1.83, 95% CI = 1.25-2.67) and severe depressive symptoms (OR = 1.17, 95% CI = 1.07-1.28) predicted SB. Longitudinal analyses revealed that patients with SB at follow-up presented with higher levels of remission in terms of positive psychotic symptoms and depression. In addition, those with a history of SB had worse GCF and visual memory than those without such antecedents. CONCLUSIONS GCF was found to be the most robust predictor of SB along with severe depressive symptomatology. Hence, poorer cognitive performance in FEP appears to emerge as a risk factor for suicidal behaviour from early stages of the illness and a comprehensive neurocognitive assessment may contribute to risk assessment.

Abstract
BACKGROUND Cognitive reserve (CR) reflects the capacity of the brain to endure neuropathology, minimize clinical manifestations and successfully complete cognitive tasks. The present study aims to determine whether high CR may constitute a moderator of cognitive functioning in bipolar disorder (BD). METHODS 102 patients with BD and 32 healthy controls were enrolled. All patients met DSM-IV criteria for I or II BD and were euthymic (YMRS≤6 and HDRS≤8) during a 6-month period. All participants were tested with a comprehensive neuropsychological battery, and a Cerebral Reserve Score (CRS) was estimated. Subjects with a CRS below the group median were classified as having low CR, whereas participants with a CRS above the median value were considered to have high CR. RESULTS Participants with BD with high CR displayed a better performance in measures of attention (digits forward: F=4.554, p=0.039); phonemic and semantic verbal fluency (FAS: F=9.328, p=0.004; and Animal Naming: F=8.532, p=0.006); and verbal memory (short cued recall of California Verbal Learning Test: F=4.236, p=0.046), after multivariable adjustment for potential confounders, including number of admissions and prior psychotic symptoms. LIMITATIONS The cross-sectional design of the study does not allow the establishment of causal inferences. Additionally, the small size of the sample may have limited some results. CONCLUSIONS High cognitive reserve may therefore be a valuable construct to explore for predicting neurocognitive performance in patients with BD regarding premorbid status.

Abstract
OBJECTIVE Cognitive reserve (CR) is a concept that was postulated as a protective factor for some clinical symptoms after the observation that there is not a direct relationship between the degree of brain damage and its clinical manifestation. This study aimed to explore the association between CR and the main outcomes in bipolar disorder (BD): cognitive functions, psychosocial functioning and perceived quality of life. METHOD A sample of 224 euthymic bipolar patients was assessed with a neuropsychological battery, the Functioning Assessment Short Test and the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). CR was calculated through three proxies: estimated premorbid Intelligent Quotient, educational level and occupational attainment. Relationships between CR and cognitive functions, psychosocial functioning and quality of life were assessed by multiple linear regression models. RESULTS Higher CR was associated with better cognitive functioning (P < 0.001 in processing speed, working memory, verbal and visual memory, and executive function; P = 0.026 in attention) and better psychosocial functioning (P = 0.008). For quality of life, CR was positively associated with the physical component of the SF-36 (P = 0.016) but negatively associated with the mental component (P = 0.004). CONCLUSION The results suggest that CR may play an important role in the course and prognosis of bipolar patients and it should be considered in both clinical and research settings related to BD.

Abstract
BACKGROUND Few randomised clinical trials have examined the efficacy of an intervention aimed at improving psychosocial functioning in bipolar disorder. AIMS To examine changes in psychosocial functioning in a group that has been enrolled in a functional remediation programme 1 year after baseline. METHOD This was a multicentre, randomised, rater-masked clinical trial comparing three patient groups: functional remediation, psychoeducation and treatment as usual over 1-year follow-up. The primary outcome was change in psychosocial functioning measured by means of the Functioning Assessment Short Test (FAST). Group×time effects for overall psychosocial functioning were examined using repeated-measures ANOVA (trial registration NCT01370668). RESULTS There was a significant group×time interaction for overall psychosocial functioning, favouring patients in the functional remediation group (F = 3.071, d.f. = 2, P = 0.049). CONCLUSIONS Improvement in psychosocial functioning is maintained after 1-year follow-up in patients with bipolar disorder receiving functional remediation.

Abstract
BACKGROUND Functional remediation is a novel intervention with demonstrated efficacy at improving functional outcome in euthymic bipolar patients. However, in a previous trial no significant changes in neurocognitive measures were detected. The objective of the present analysis was to test the efficacy of this therapy in the enhancement of neuropsychological functions in a subgroup of neurocognitively impaired bipolar patients. METHOD A total of 188 out of 239 DSM-IV euthymic bipolar patients performing below two standard deviations from the mean of normative data in any neurocognitive test were included in this subanalysis. Repeated-measures analyses of variance were conducted to assess the impact of the treatment arms [functional remediation, psychoeducation, or treatment as usual (TAU)] on participants' neurocognitive and functional outcomes in the subgroup of neurocognitively impaired patients. RESULTS Patients receiving functional remediation (n = 56) showed an improvement on delayed free recall when compared with the TAU (n = 63) and psychoeducation (n = 69) groups as shown by the group × time interaction at 6-month follow-up [F 2,158 = 3.37, degrees of freedom (df) = 2, p = 0.037]. However, Tukey post-hoc analyses revealed that functional remediation was only superior when compared with TAU (p = 0.04), but not with psychoeducation (p = 0.10). Finally, the patients in the functional remediation group also benefited from the treatment in terms of functional outcome (F 2,158 = 4.26, df = 2, p = 0.016). CONCLUSIONS Functional remediation is effective at improving verbal memory and psychosocial functioning in a sample of neurocognitively impaired bipolar patients at 6-month follow-up. Neurocognitive enhancement may be one of the active ingredients of this novel intervention, and, specifically, verbal memory appears to be the most sensitive function that improves with functional remediation.

Abstract
BACKGROUND Neurocognitive impairment is a core component of schizophrenia. However, patients show great variability in the level and course of deficits. The goal of the present longitudinal study was to identify predictors of neurocognitive impairment in first episode psychosis patients. METHODS Neurocognitive performance was analyzed in a cohort of 146 patients 3 years after a first episode non-affective psychosis. Subgroups, impaired vs. unimpaired, were compared on baseline clinical, neuropsychological, premorbid and sociodemographic characteristics. RESULTS Fifty-nine percent of participants presented general neurocognitive impairment and regression analyses demonstrated that clinical and sociodemographic characteristics were not predictive variables. A model composed of premorbid IQ, verbal memory and motor dexterity correctly classified 79.6% of the individuals. CONCLUSIONS The present study gives information on frequency and neurocognitive profile of subtypes of patients showing impairment. Our results suggest general neurocognitive impairment is a trait dimension of the disorder related to specific cognitive dysfunctions.

Abstract
OBJECTIVE To analyze, in a general population sample, clustering of delusional and hallucinatory experiences in relation to environmental exposures and clinical parameters. METHOD General population-based household surveys of randomly selected adults between 18 and 65 years of age were carried out. SETTING 52 countries participating in the World Health Organization's World Health Survey were included. PARTICIPANTS 225 842 subjects (55.6% women), from nationally representative samples, with an individual response rate of 98.5% within households participated. RESULTS Compared with isolated delusions and hallucinations, co-occurrence of the two phenomena was associated with poorer outcome including worse general health and functioning status (OR = 0.93; 95% CI: 0.92-0.93), greater severity of symptoms (OR = 2.5 95% CI: 2.0-3.0), higher probability of lifetime diagnosis of psychotic disorder (OR = 12.9; 95% CI: 11.5-14.4), lifetime treatment for psychotic disorder (OR = 19.7; 95% CI: 17.3-22.5), and depression during the last 12 months (OR = 11.6; 95% CI: 10.9-12.4). Co-occurrence was also associated with adversity and hearing problems (OR = 2.0; 95% CI: 1.8-2.3). CONCLUSION The results suggest that the co-occurrence of hallucinations and delusions in populations is not random but instead can be seen, compared with either phenomenon in isolation, as the result of more etiologic loading leading to a more severe clinical state.

Abstract
BACKGROUND Cognitive remediation is accepted as an important therapeutic intervention in schizophrenia, but few studies provide data on whether the benefits extend to affective disorders. OBJECTIVES To review quantitatively studies of cognitive remediation with samples that included cases of schizoaffective disorder, affective psychosis, unipolar and/or bipolar disorders. METHODS Twenty one studies met preliminary inclusion criteria, comprising a total of 940 participants of which 35% had an affective or schizoaffective disorder. Effect sizes (ES) for pre- to post-intervention change in cognitive performance were estimated. RESULTS A meta-analysis of 16 studies gave a pooled ES for change in cognitive function of 0.32 (95% Confidence Intervals 0.20 to 0.43) and produced statistical homogeneity. Overall, ES were significantly positively correlated with higher proportion of schizo-affective and affective cases (r=0.61; p=0.007), even when age, gender and duration of therapy were included as covariates in the analysis (r=.59, p=0.017). LIMITATIONS The quality of and small number of affective disorder only studies mean the findings must be treated with caution. CONCLUSIONS The estimated ES reflect those reported in the literature on cognitive remediation for schizophrenia. As such a conservative interpretation is that cognitive remediation has at least equivalent benefits in affective and schizo-affective disorder as demonstrated in schizophrenia. Further studies are urgently required to examine the durability of any gains with cognitive remediation in affective populations and to determine if any changes in cognitive deficits lead to improvements in symptoms or functioning and/or whether post-intervention cognitive changes differ in character or magnitude from those reported in schizophrenia.

Abstract
This study aimed to determine the incidence of AIDS dementia complex (ADC), the clinical data which distinguish it from other neurological complications of HIV infection, and the impact of zidovudine (AZT) therapy on the appearance and course of this condition. Data on the neurological complications of HIV patients treated at a community hospital from 1988 to 1992 were collected prospectively. Out of 500 AIDS patients treated at the hospital, there were 142 patients with neurological complications, with an average of 1.42 complications/patient There were 23 patients diagnosed as having ADC; with an estimated incidence of 4.6%, it was the most frequent neurological complication, after cerebral toxoplasmosis. Age was higher in patients with ADC as first manifestation of AIDS with respect to ADC patients with previous AIDS diagnosed. Compared with the group of patients suffering from other neurological complications, patients with ADC showed significant differences in several biological markers of progression to AIDS, such as hemoglobin, hematocrit, global lymphocyte count, serum β2-microglobulin and serum IgA. CD4 count was similar in both groups. Ten ADC patients had been treated previously with AZT. Dementia continued progressing in seven of these patients and remained stable in three. Of the other 13 cases not treated previously with the drug, eight received AZT therapy, and a favourable response was obtained in three patients (p = 0.068). ADC represents a major neurological complication in AIDS patients. AZT therapy may delay the appearance of ADC, but not prevent it. A trend towards a favourable response to AZT was observed in ADC patients who had not been treated with it previously.

Abstract
OBJECTIVE To test the impact of socio-economic and psychological adversity and healthcare on long-term recovery from depression. METHOD A community sample of 347 people with depressive disorders was followed up after 9 years. Baseline socio-economic adversity, social support, healthcare use, and psychiatric history were identified. Respondents completed self-report instruments on current depressive status (Beck depression inventory) and longstanding psychosocial adversity (sexual, physical or emotional abuse). Univariate analyses tested for association between recovery and respondent characteristics. RESULTS Follow-up was achieved for 182 (52%) of the sample, of whom 75 (41%) indicated recovery from depression. Psychological adversity definitely and socio-economic adversity probably were associated with lack of recovery. Baseline healthcare had no apparent impact on outcome. Rurality and support after life events were associated with recovery. History of depression was associated with non-recovery. CONCLUSION Psychological adversity is, and socio-economic adversity may be, associated with long-term non-recovery from depression in community settings.

Abstract
BACKGROUND The impact of different levels of depression severity on quality of life (QoL) is not well studied, particularly regarding ICD-10 criteria. The ICD classification of depressive episodes in three levels of severity is also controversial and the less severe category, mild, has been considered as unnecessary and not clearly distinguishable from non-clinical states. The present work aimed to test the relationship between depression severity according to ICD-10 criteria and several dimensions of functioning as assessed by Medical Outcome Study (MOS) 36-item Short Form general health survey (SF-36) at the population level. METHOD A sample of 551 participants from the second phase of the Outcome of Depression International Network (ODIN) study (228 controls without depression and 313 persons fulfilling ICD criteria for depressive episode) was selected for a further assessment of several variables, including QoL related to physical and mental health as measured with the SF-36. RESULTS Statistically significant differences between controls and the depression group were found in both physical and mental markers of health, regardless of the level of depression severity; however, there were very few differences in QoL between levels of depression as defined by ICD-10. Regardless of the presence of depression, disability, widowed status, being a woman and older age were associated with worse QoL in a structural equation analysis with covariates. Likewise, there were no differences according to the type of depression (single-episode versus recurrent). CONCLUSIONS These results cast doubt on the adequacy of the current ICD classification of depression in three levels of severity.

Abstract
BACKGROUND Bipolar disorder has generally been regarded as having a better functional outcome than schizophrenia. However, studies have suggested low functioning in bipolar patients even when they are in clinical remission. Our aim was to determine the degree of functioning and disability in bipolar patients. Secondly, we reviewed factors potentially associated with the low functioning of bipolar patients. METHOD The authors conducted an extensive Medline and Pubmed search of the published literature from 1980 up to December 2007, using a variety of search terms to find relevant articles. Bibliographies of retrieved papers were further analysed for publications of interest. Articles that reported clinically significant findings on functioning and disability, and research reports were reviewed in detail. RESULTS From these articles, we determined that bipolar disorder is associated with significant impairment in work, family and social life, beyond the acute phases of the illness. The aspects that appear to increase the risk of low functioning and disability in bipolar patients are mainly subsyndromal symptoms and neurocognitive impairment, among others. CONCLUSIONS Suitable pharmacological and psychological interventions may improve the level of functioning and reduce the disability in bipolar patients. Potential targets to be considered for intervention should be residual symptoms, comorbid conditions and neurocognitive deficits. Further research is required to better identify the factors that best predict functioning in bipolar patients.

Abstract
BACKGROUND For some phenomena the mean of population distributions predicts the proportion of people exceeding a threshold value. AIMS To investigate whether in depression, too, the population mean predicts the number of individuals at the extreme end of the distribution. METHOD We used data from the European Outcome in Depression International Network (ODIN) study from populations in Finland, Norway and the UK to create models that predicted the prevalence of depression based on the mean Beck Depression Inventory (BDI) score. The models were tested on data from Ireland and Spain. RESULTS Mean BDI score correlated well with the prevalence of depression determined by clinical interviews. A model based on the beta distribution best fitted the BDI distribution. Both models predicted the depression prevalence in Ireland and Spain fairly well. CONCLUSIONS The mean of a continuous population distribution of mood predicts the prevalence of depression. Characteristics of both individuals and populations determine depression rates.

Abstract
BACKGROUND Access to employment for people with intellectual disability (ID) has become a social priority. The aim of the present study is to try to determine which variables [sociodemographic variables, intelligence quotient (IQ), presence or absence of a psychiatric disorder, functioning, self-determination, and behavioural problems] could most reliably account for access to remunerated employment of people with ID. METHODS Two groups of people with ID participated in this study: (1) 69 workers in a sheltered-employment programme; and (2) 110 clients of programmes in sheltered workshops. Both programmes were run by the Pardo-Valcarce Foundation in Madrid (Spain). The following variables were assessed for every participant: IQ, functioning, behavioural problems, self-determination and presence of psychiatric symptoms. A binary logistic regression analysis was carried out in order to identify the variables that best explained work outcome (sheltered workshop programme vs. sheltered employment programme). RESULTS Although IQ showed no significant differences between the two groups of participants, the remaining variables did: behavioural problems, functioning, psychiatric symptoms and self-determination significantly explained work outcome. As for sociodemographic variables, whereas gender did not show any significant relationship with the labour status of the participants, significant differences were found when considering variables such as age and pension benefits. CONCLUSIONS All the main variables considered, except IQ, turned out to be significant. Our findings should be considered encouraging, as they apparently show that both personal and social efforts can help individuals to overcome their low intellectual functioning in order to achieve access to employment. Such study highlights the importance of a prior psychopathological evaluation and efforts to enhance self-determination in order to improve work inclusion for people with ID.

Abstract
BACKGROUND There is little information on the psychometric properties of instruments for assessing family care burden in adults with intellectual disabilities (ID). The aim of this study is therefore to analyse the usefulness of the 'Subjective and Objective Family Burden Interview' (SOFBI) in the assessment of principal caregivers in Spain. METHODS The SOFBI was administered to 166 principal caregivers of adults with ID in a vocational centre. The psychometric analysis included: internal consistency, inter-rater and test-retest reliability, construct validity, convergent validity with the World Health Organization's Disability Assessment Schedule II, and feasibility. RESULTS The Cronbach's alpha was 0.88 for the overall interview and always above 0.7 in the quantitative subdomains. The Kappa coefficients for test-retest were between 0.5 and 0.8, whereas inter-rater agreement was nearly perfect. Maximum-likelihood factor analysis showed four well-defined factors, which fitted the previously designed domains. Feasibility was also good. CONCLUSIONS The SOFBI is a multi-domain, modular instrument which is feasible, reliable and valid for measuring the burden of family caregivers to adults with ID living in the community.

Abstract
OBJECTIVE Care planning integrates a growing number of disciplines, research fields and analysis techniques. A framework of the main areas of interest with regard to evidence-based health care in mental health is provided here. METHOD The framework is based on the experience of working with data analysts and health and social decision makers at the PSICOST/RIRAG network, a Spanish research association which includes psychiatrists, health economists and health policy experts, as well as on a review of the literature. RESULTS Three main areas have been identified and described here: outcomes management, knowledge discovery from data, and decision support systems. Their use in mental health care is reviewed. CONCLUSION It is important to promote bridging strategies among these new fields in order to enhance communication and information transfer between the different parts involved in mental health decision making: i) clinicians and epidemiologists, ii) data analysts, iii) care policy makers and other end-users.

Abstract
BACKGROUND This study sought to evaluate the acceptance of two brief psychological interventions for depressed individuals, contacted through a community survey, and to look for predictors of adherence at the patient level. METHOD The authors used data from the Outcomes of Depression International Network (ODIN) study, which included a randomized controlled trial in which depressed individuals from five European countries, and nine geographical areas were assigned to one of three groups: individual problem-solving treatment, group psychoeducation, or control group. In this analysis, we included all of the individuals who had been assigned to one of the psychological interventions. Compliance with intervention was defined in two different ways. Multiple logistic regression was used to see which variables might predict an individual's compliance with psychological treatment. RESULTS Psychological intervention was offered to 236 subjects. Treatment was completed by 128 subjects and not by 108 (compliance definition A). Three variables were found to have an effect on compliance A: the presence of a confidant, the use of antidepressant medication during the previous 6 months, and the previous use of any social or health services. On the other hand, 164 subjects had agreed to at least start the treatment, and 72 had not (compliance definition B). The three factors associated with compliance B were presence of a confidant, previous use of services, and the 'desire for change' score. CONCLUSIONS Social support and previous use of services are the main predictors of compliance with a psychological treatment in depressed individuals from the community. Implications for clinical practice and community programs are discussed.

Abstract
INTRODUCTION Functioning is increasingly being taken into account when assessing the impact of bipolar disorder (BD) on the individual, as well as the effectiveness of treatments. With the International Classification of Functioning, Disability and Health (ICF), we can now rely on a globally agreed-upon framework and system for classifying the typical spectrum of problems in functioning, given the environmental context in which subjects live. ICF Core Sets are subgroups of ICF items selected to capture those aspects of functioning that are most likely to be affected by specific disorders. Within a given disorder, both Brief and Comprehensive Core Sets can be established to serve specific purposes. OBJECTIVE The aim of this paper is to outline the development process of the ICF Core Sets for BD. METHODS The final definition of ICF Core Sets for BD will be determined at an ICF Core-Sets Consensus Conference, which will integrate evidence from preliminary studies, namely (a) semi-structured interviews with people with BD in different countries, (b) a Delphi exercise with international experts participating and (c) a cross-sectional study. CONCLUSION ICF Core Sets are being designed with the goal of providing useful standards for research, clinical practice and teaching. We believe that these ICF Core Sets for BD will stimulate research leading to improved understanding of functioning, disability and health in BD. Such research, we hope, will lead to interventions and accommodations to improve restoration and maintenance of functioning and minimise disability among people with BD throughout the world.

Abstract
INTRODUCTION Few studies have examined the clinical, neuropsychological and pharmacological factors involved in the functional outcome of bipolar disorder despite the gap between clinical and functional recovery. METHODS A sample of 77 euthymic bipolar patients were included in the study. Using an a priori definition of low versus good functional outcome, based on the psychosocial items of the Global Assessment of Functioning (GAF, DSM-IV), and taking also into account their occupational adaptation, the patients were divided into two groups: good or low occupational functioning. Patients with high (n = 46) and low (n = 31) functioning were compared on several clinical, neuropsychological and pharmacological variables and the two patient groups were contrasted with healthy controls (n = 35) on cognitive performance. RESULTS High- and low-functioning groups did not differ with respect to clinical variables. However, bipolar patients in general showed poorer cognitive performance than healthy controls. This was most evident in low-functioning patients and in particular on verbal memory and executive function measures. CONCLUSIONS Low-functioning patients were cognitively more impaired than highly functioning patients on verbal recall and executive functions. The variable that best predicted psychosocial functioning in bipolar patients was verbal memory.

Abstract
OBJECTIVE To estimate the cost-effectiveness of interventions for reducing the burden of schizophrenia in Spain. METHOD The study examined the cost-effectiveness of seven different types of clinical interventions at the level of Spanish population: i) current situation; ii) older antipsychotics alone; iii) new antipsychotics alone (risperidone); iv) older antipsychotics plus psychosocial treatment; v) new antipsychotics plus psychosocial treatment; vi) older antipsychotics plus case management and psychosocial treatment; vii) new antipsychotics plus case management and psychosocial treatment. RESULTS Interventions based on the combination of haloperidol with psychosocial treatment or psychosocial treatment plus case management proved to be the most efficient strategies. CONCLUSION The relatively modest additional cost of concurrent psychosocial treatment has significant health gains, thereby making such a combined strategy for schizophrenia more cost-effective than pharmacology alone.

Abstract
Serotonin syndrome, which occurs as a result of enhanced serotonin concentration in the central nervous system, is a well-known adverse effect of serotonin-active medications. The concomitant use of antidepressant drugs associated with lithium as a co-adjuvant seems to increase the risk of this adverse reaction. We report a case of the serotonin syndrome during treatment with lithium and venlafaxine, an antidepressant with a dual selective re-uptake inhibition mechanism, and review the literature for similar cases. A 71-year-old woman developed serotonin syndrome while receiving treatment with moderate doses of lithium and venlafaxine for refractory depression. She had been taking higher doses of venlafaxine during the previous months with no significant secondary effects. Use of the Naranjo adverse drug reaction probability algorithm indicated a probable relationship between serotonin syndrome and treatment with lithium and venlafaxine.
