Background: Frequent attenders to GP clinics can place an unnecessary burden on primary care. Interventions to reduce frequent attendance have had mixed results.Aim: To assess the effectiveness of a GP intervention to reduce frequent-attender consultations.Design Of Study: Randomised controlled trial with frequent attenders divided into an intervention group and two control groups (one control group was seen by GPs also providing care to patients undergoing the intervention).Setting: A health centre in southern Spain.Method: Six GPs and 209 randomly-selected frequent attenders participated. Three GPs were randomly allocated to perform the new intervention: of the 137 frequent attenders registered with these three GPs, 66 were randomly allocated to receive the intervention (IG) and 71 to a usual care control group (CG2). The other three GPs offered usual care to the other 72 frequent attenders (CG1). The main outcome measure was the total number of consultations 1 year post-intervention. Baseline measurements were recorded of sociodemographic characteristics, provider-user interface, chronic illnesses, and psychosocial variables. GPs allocated to the new intervention received 15 hours' training which incorporated biopsychosocial, organisational, and relational approaches. After 1 year of follow-up frequent attenders were contacted. An intention-to-treat analysis was used.Results: A multilevel model was built with three factors: time, patient, and doctor. After adjusting for covariates, the mean number of visits at 1 year in IG was 13.10 (95% confidence interval [CI]=11.39 to 14.94); in the CG1 group was 19.37 (95% CI=17.31 to 21.55); and in the CG2 group this was 16.72 (95% CI=4.84 to 18.72).Conclusion: The new intervention with GPs resulted in a significant and relevant reduction in frequent-attender consultations. Although further trials are needed, this intervention is recommended to GPs interested in reducing consultations by their frequent attenders. [ABSTRACT FROM AUTHOR]

Purpose: Our aim is to examine which risk factors have a greater impact in women than in men on the risk of major depressive disorder (MDD) and whether factors differ between a possible recurrent MDD and a first onset of MDD.Methods: Prospective cohort study of general practice attendees in seven countries, who were followed up at 6 and 12 months (predictD). Absolute risk differences (interaction contrast) across sex for onset of DSM-IV MDD after 6 or 12 months of follow-up were estimated for 35 risk factors from 7101 participants without MDD at baseline.Results: A total of 599 participants (80% female) had an onset of MDD at 6 or 12 months. Most risk factors had a greater impact in women than in men on the risk of MDD and were not restricted to a specific class of risk factors. After we stratified for a history of depressive symptoms, we found that the impact of risk factors across sex was generally stronger on possible recurrent MDD than on a first onset of MDD.Conclusions: Our findings may partly account for the observed difference in incidence of MDD between men and women.

Schizophrenia is a heterogeneous and severe psychotic disorder. Epidemiological findings have suggested that the exposure to infectious agents such as Toxoplasma gondii (T. gondii) is associated with an increased risk for schizophrenia. On the other hand, there is evidence involving the catechol-O-methyltransferase (COMT) Val105/158Met polymorphism in the aetiology of schizophrenia since it alters the dopamine metabolism. A case−control study of 141 patients and 142 controls was conducted to analyse the polymorphism, the prevalence of anti-T. gondii IgG, and their interaction on the risk for schizophrenia. IgG were detected by ELISA, and genotyping was performed with TaqMan Real-Time PCR. Although no association was found between any COMT genotype and schizophrenia, we found a significant association between T. gondii seropositivity and the disorder (χ2 = 11.71; p-value < 0.001). Furthermore, the risk for schizophrenia conferred by T. gondii was modified by the COMT genotype, with those who had been exposed to the infection showing a different risk compared to that of nonexposed ones depending on the COMT genotype (χ2 for the interaction = 7.28, p-value = 0.007). This study provides evidence that the COMT genotype modifies the risk for schizophrenia conferred by T. gondii infection, with it being higher in those individuals with the Met/Met phenotype, intermediate in heterozygous, and lower in those with the Val/Val phenotype.

The aims of this study were to determine the prevalence of severe mental illness (SMI) in patients in contact with mental health services and to determine the factors associated with SMI. A total of 260 patients who met diagnostic criteria for SMI were assessed using the Global Assessment of Functioning (GAF) scale and Health of the Nation Outcome Scales. The overall prevalence of SMI was 6.08 per thousand. According to the three different cutoff points with GAF, the prevalence of SMI ranged from 5.38 per thousand under the weak criterion (GAF < 70) to 1.01 per thousand under the strict criterion (GAF < 50). In the regression model, the dependent variable (presence of SMI) was defined using a GAF < 60, and the variables independently associated with the dependent variable were years of disease duration since diagnose, mental health service use, alcohol or other substance abuse, and depressive anxiety and other psychological symptoms.

Background: Little is known about the risk of progressing to hazardous alcohol use in abstinent or low-risk drinkers., Aim: To develop and validate a simple brief risk algorithm for the onset of hazardous alcohol drinking (HAD) over 12 months for use in primary care., Design and Setting: Prospective cohort study in 32 health centres from six Spanish provinces, with evaluations at baseline, 6 months, and 12 months., Method: Forty-one risk factors were measured and multilevel logistic regression and inverse probability weighting were used to build the risk algorithm. The outcome was new occurrence of HAD during the study, as measured by the AUDIT., Results: From the lists of 174 GPs, 3954 adult abstinent or low-risk drinkers were recruited. The 'predictAL-10' risk algorithm included just nine variables (10 questions): province, sex, age, cigarette consumption, perception of financial strain, having ever received treatment for an alcohol problem, childhood sexual abuse, AUDIT-C, and interaction AUDIT-C*Age. The c-index was 0.886 (95% CI = 0.854 to 0.918). The optimal cutoff had a sensitivity of 0.83 and specificity of 0.80. Excluding childhood sexual abuse from the model (the 'predictAL-9'), the c-index was 0.880 (95% CI = 0.847 to 0.913), sensitivity 0.79, and specificity 0.81. There was no statistically significant difference between the c-indexes of predictAL-10 and predictAL-9., Conclusion: The predictAL-10/9 is a simple and internally valid risk algorithm to predict the onset of hazardous alcohol drinking over 12 months in primary care attendees; it is a brief tool that is potentially useful for primary prevention of hazardous alcohol drinking., (© British Journal of General Practice 2017.)

Background: Sadness and anhedonia (loss of interest in activities) are central symptoms of major depression. However, not all people with these symptoms meet diagnostic criteria for major depression. We aimed to assess the importance of suicidality in the outcomes for primary care patients who present with sadness and anhedonia., Method: Cohort study of 2,599 unselected primary care attenders in six European countries followed up at 6 and 12 months., Results: 1) In patients with sadness and/or anhedonia who were not depressed at entry to the study, suicide plans (OR = 3.05; 95 % CI = 1.50-6.24; p = 0.0022) and suicide attempts (OR = 9.08; 95 % CI = 2.57-32.03; p = 0.0006) were significant predictors of developing new onset depression at 6 or 12 months. 2) In patients with sadness and/or anhedonia who met CIDI criteria for major depression at entry, suicidal ideation (OR = 2.93; 95 % CI = 1.70-5.07; p = 0.0001), suicide plans (OR = 3.70; 95 % CI = 2.08-6.57; p < 0.0001), and suicide attempts (OR = 3.33; 95 % CI = 1.47-7.54; p = 0.0040) were significant predictors of persistent depression at 6 or 12 months., Conclusions: Three questions on suicidality could help primary care professionals to assess such patients more closely without necessarily establishing whether they meet criteria for major depression.

Background: There is limited evidence for a moderating role of both serotonin transporter (SERT) and brain-derived neurotrophic factor (BDNF) genes on the risk for major depression (MD) developing after childhood maltreatment. However, research on this topic remains inconclusive, and there is a lack of data from longitudinal studies with large and representative population samples. Our study aimed to clarify whether, in the presence of previous childhood maltreatment, individuals carrying low functional alleles for both SERT 5-HTTLPR and BDNF Val66Met polymorphisms had a higher risk for MD., Methods: We explored 2- and 3-way gene (SERT and BDNF) × environment (childhood maltreatment) interactions in a large sample of Spanish adults who were followed up over a 3-year period and assessed in person for both DSM-IV MD and exposure to childhood maltreatment., Results: Our study included 2679 participants. Those with both the 5-HTTLPR s allele and the BDNF Met allele showed the highest risk of MD if they had previously experienced emotional (z = 2.08, p = 0.037), sexual (z = 2.19, p = 0.029) or any kind of childhood abuse (z = 2.37, p = 0.018). These 3-way interactions remained significant regardless of whether the 5-HTTLPR triallelic or the 5-HTTLPR biallelic polymorphisms were included in the analyses., Limitations: Retrospective assessment of childhood maltreatment may have resulted in a moderate degree of recall bias., Conclusion: Our results confirm that the risk of depression conferred by childhood maltreatment is modified by variation at both SERT and BDNF genes.

Background: There are no risk algorithms for the onset of anxiety syndromes at 12 months in primary care. We aimed to develop and validate internally a risk algorithm to predict the onset of anxiety syndromes at 12 months., Methods: A prospective cohort study with evaluations at baseline, 6 and 12 months. We measured 39 known risk factors and used multilevel logistic regression and inverse probability weighting to build the risk algorithm. Our main outcome was generalized anxiety, panic and other non-specific anxiety syndromes as measured by the Primary Care Evaluation of Mental Disorders, Patient Health Questionnaire (PRIME-MD-PHQ). We recruited 3,564 adult primary care attendees without anxiety syndromes from 174 family physicians and 32 health centers in 6 Spanish provinces., Results: The cumulative 12-month incidence of anxiety syndromes was 12.2%. The predictA-Spain risk algorithm included the following predictors of anxiety syndromes: province; sex (female); younger age; taking medicines for anxiety, depression or stress; worse physical and mental quality of life (SF-12); dissatisfaction with paid and unpaid work; perception of financial strain; and the interactions sex*age, sex*perception of financial strain, and age*dissatisfaction with paid work. The C-index was 0.80 (95% confidence interval=0.78-0.83) and the Hedges' g=1.17 (95% confidence interval=1.04-1.29). The Copas shrinkage factor was 0.98 and calibration plots showed an accurate goodness of fit., Conclusions: The predictA-Spain risk algorithm is valid to predict anxiety syndromes at 12 months. Although external validation is required, the predictA-Spain is available for use as a predictive tool in the prevention of anxiety syndromes in primary care.

Background: People with schizophrenia face prejudice and discrimination from a number of sources including professionals and families. The degree of stigma perceived and experienced varies across cultures and communities. We aimed to develop a cross-cultural measure of the stigma perceived by people with schizophrenia., Method: Items for the scale were developed from qualitative group interviews with people with schizophrenia in six countries. The scale was then applied in face-to-face interviews with 164 participants, 103 of which were repeated after 30 days. Principal Axis Factoring and Promax rotation evaluated the structure of the scale; Horn's parallel combined with bootstrapping determined the number of factors; and intra-class correlation assessed test-retest reliability., Results: The final scale has 31 items and four factors: informal social networks, socio-institutional, health professionals and self-stigma. Cronbach's alpha was 0.84 for the Factor 1; 0.81 for Factor 2; 0.74 for Factor 3, and 0.75 for Factor 4. Correlation matrix among factors revealed that most were in the moderate range [0.31-0.49], with the strongest occurring between perception of stigma in the informal network and self-stigma and there was also a weaker correlation between stigma from health professionals and self-stigma. Test-retest reliability was highest for informal networks [ICC 0.76 [0.67 -0.83]] and self-stigma [ICC 0.74 [0.64-0.81]]. There were no significant differences in the scoring due to sex or age. Service users in Argentina had the highest scores in almost all dimensions., Conclusions: The MARISTAN stigma scale is a reliable measure of the stigma of schizophrenia and related psychoses across several cultures. A confirmatory factor analysis is needed to assess the stability of its factor structure.

Objective: Existing measures of needs in severe mental illness have been developed mainly from professionals' viewpoints and are Eurocentric. Our aim was to standardize a measure of the needs of people with schizophrenia across several cultures and based on users' own viewpoints., Method: An instrument to measure needs, based on qualitative data on users', carers' and professionals' views, was tested in 164 people with schizophrenia or related psychoses in six countries. Participants underwent face-to-face interviews, one third of which were repeated 30 days later. Principal axis factoring and Promax rotation evaluated scale structure; Horn's parallel combined with bootstrapping determined the number of factors; and intra-class correlation assessed test-retest reliability., Results: The instrument contained four factors: (1) health needs; (2) work and leisure needs; (3) existential needs; and (4) needs for support in daily living. Cronbach's α for internal consistency was 0.81, 0.81, 0.77 and 0.76 for factors 1-4 and 0.81 for the scale as a whole. Correlation between factors was of moderate range for the first three factors (0.41-0.50) and low for the fourth factor (0.14-0.29). Intra-class correlation coefficient for test-retest reliability was 0.74 (0.64-0.82) for the whole scale. Mean item score on needs for support in daily living was lower than for the other factors., Conclusions: The MARISTÁN Scale of Needs evaluates needs from the patient perspective and it is a valid instrument to measure the needs of people with severe mental illness across cultures.

Objectives: To compare the prevalence of elder abuse using a multilevel approach that takes into account the characteristics of participants as well as socioeconomic indicators at city and country level., Methods: In 2009, the project on abuse of elderly in Europe (ABUEL) was conducted in seven cities (Stuttgart, Germany; Ancona, Italy; Kaunas, Lithuania, Stockholm, Sweden; Porto, Portugal; Granada, Spain; Athens, Greece) comprising 4467 individuals aged 60-84 years. We used a 3-level hierarchical structure of data: 1) characteristics of participants; 2) mean of tertiary education of each city; and 3) country inequality indicator (Gini coefficient). Multilevel logistic regression was used and proportional changes in Intraclass Correlation Coefficient (ICC) were inspected to assert explained variance between models., Results: The prevalence of elder abuse showed large variations across sites. Adding tertiary education to the regression model reduced the country level variance for psychological abuse (ICC=3.4%), with no significant decrease in the explained variance for the other types of abuse. When the Gini coefficient was considered, the highest drop in ICC was observed for financial abuse (from 9.5% to 4.3%)., Conclusion: There is a societal and community level dimension that adds information to individual variability in explaining country differences in elder abuse, highlighting underlying socioeconomic inequalities leading to such behavior., (Copyright © 2014 Elsevier Inc.

Background: The List of Threatening Experiences (LTE) questionnaire is frequently used to assess stressful events; however, studies of its psychometric properties are scarce. We examined the LTE's reliability, factorial structure, construct validity and explored the association between LTE scores and psychosocial variables and mental disorders., Method: This study involved interviewing 5442 primary care attendees from Spain. Associations between four different methods of quantifying LTE scores, psychosocial factors, major depression (CIDI), anxiety disorders (PRIME-MD), alcohol misuse and dependence (AUDIT) were measured., Results: The LTE showed high test-retest reliability (Kappa range=0.61-0.87) and low internal consistency (α=0.44). Tetrachoric factorial analysis yielded four factors (spousal and relational problems; employment and financial problems; personal problems; illness and bereavement in close persons). Logistic multilevel regression found a strong association between greater social support and a lower occurrence of stressful events (OR range=0.36-0.79). The association between religious-spiritual beliefs and the LTE, was weaker. The association between mental disorders and LTE scores was greater for depression (OR range=1.64-2.57) than anxiety (OR range=1.35-1.97), though the highest ORs were obtained with alcohol dependence (OR range=2.86-4.80). The ordinal score (ordinal regression) was more sensitive to detect the strength of association with mental disorders., Limitations: We are unable to distinguish the direction of the association between stressful events, psychosocial factors and mental disorders, due to our cross-sectional design of the study., Conclusions: The LTE is a valid and reliable measure of stress in mental health, and the strength of association with mental disorders depends on the method of quantifying LTE scores., (© 2013 Elsevier B.V.

Purpose: Major depressive disorder may vary according to number and duration of episodes. It is unclear whether risk factors for onset of multiple or long episodes of depression (MDE) differ from risk factors for the onset of single and short ones., Methods: Data were used from a cohort study of 5,256 GP attendees without major depressive disorder at baseline, who were followed up three times (predictD). The numbers and duration of MDE were noted and categorized into no episodes, single and short (≤3 months), and multiple or long (>3 months) episodes at follow-up. Log-binomial regression models were used to calculate relative risks between the groups for 18 risk factors examined at baseline., Results: 165 persons (3 %) had a single and short MDE and 328 (6 %) had multiple or long MDE at follow-up. Lower education, anxiety, problems at work and financial strain significantly increased the risk of multiple or long MDE when compared to single and short MDE. Younger people were at reduced risk of multiple or long MDE., Conclusions: Our findings suggest that several risk factors can be identified that may help to predict onset of different types of MDE. These factors are easy to assess and may be used in the prevention of depression.

Background: Depression, anxiety and physical function may be bi-directionally related. We aim to estimate the strength of the longitudinal associations between depression, anxiety and physical function., Methods: Prospective cohort study of general practice attendees across Europe (N=4757) assessed at baseline, 6, 12 and 24 months. Main outcome measures were Diagnostic and Statistical Manual of Mental Disorders-IV major depression, Patient Health Questionnaire anxiety and Short Form 12 physical function. Complete-case analyses using random coefficient models and logistic regression models were performed., Results: Those with depression (β=-1.90, 95% CI -3.42 to -0.39), anxiety (β=-4.12, 95% CI -5.39 to -2.86) or depression and anxiety (β=-5.74, 95% CI -7.38 to -4.10) had lower levels of physical function at baseline and over time compared with no diagnosis after adjustment for potential confounders. Physical function increased over time, but the rate of increase was not different between the groups. When compared with depression, those with anxiety (β=-2.22, 95% CI -4.08 to -0.36) or depression and anxiety (β=-3.83, 95% CI -5.95 to -1.71) had significantly lower levels of physical function at baseline. Lower levels of physical function at baseline were associated with onset of depression (OR 1.83, 95% CI 1.08 to 3.10) but even stronger with anxiety (OR 2.79, 95% CI 1.52 to 5.12) or depression and anxiety (OR 5.05, 95% CI 2.55 to 9.99) during 24 months compared with no dysfunction, after adjustment for potential confounders., Conclusion: It is essential to prevent lower levels of physical function as this is likely to lead to onset of depression and anxiety over time.

Background: The authors examined an additive model for the association of life events and age with onset of major depressive disorder (MDD) and whether the combination of life events and age posed greater risk than the sum of their independent effects., Methods: Data were used from a prospective cohort study of 10,045 general practice attendees (PredictD). We included those without MDD at baseline (N=8293). We examined age divided into tertiles and into 10 year groups. Life events were assessed at baseline using the List of Threatening Life Experiences Questionnaire and categorized according to type. Main outcome measure was onset of DSM-IV MDD at 6 or 12 months of follow-up. The authors calculated Relative Excess Risks due to Interaction (RERI)., Results: 6910 persons (83.3%) had a complete follow-up, of whom 589 (8.5%) had an onset of MDD (166 younger, 254 middle aged and 169 older). The combined effect of personal problems (RERI=1.30; 95% CI 0.29 to 2.32), events in family or friends (RERI=1.23; 95% CI 0.28 to 2.19), or problems with law (RERI=1.57; 95% CI 0.33 to 2.82) and middle age was larger than the sum of individual effects., Limitations: Lower response to recruitment in the UK and the Netherlands., Conclusions: Recent life events carry the largest risk of onset of MDD in mid-life. Understanding the different vulnerability to life events according to age may help to indicate groups at a particular risk and assist in preventive strategies., (Copyright © 2011 Elsevier B.V.

This prospective analysis aimed to study the influence of psychopathological dimensions on the global functioning of persons suffering from psychotic disorders, taking into account the role of a broad range of potential confounders. A large international cohort (n=1888) with ICD-10 non-affective psychosis was evaluated both at baseline during a hospital admission and three months after discharge. Trained interviewers administered a global functioning scale (GAF) and a psychopathological scale (BPRS) at baseline and follow-up). Baseline BPRS psychopathological dimensions were extracted using Principal Component Analysis. Results of multiple linear regression analyses demonstrated that affective symptoms (depressive or manic) prospectively predict a better global functioning, whilst agitation/cognitive symptoms determined poorer global functioning. Other predictors showing an independent effect on better global functioning were medication compliance, country of residence, female gender, married or coupled status, younger age and having a diagnosis of schizoaffective disorder rather than schizophrenia or other ICD-10 psychosis. A predicting model for global functioning in patients with psychosis is provided, showing that assessment of affective and agitation/cognitive symptoms should be emphasised during admission as they can be more informative than positive/negative symptoms in prospectively planning follow-up care that is geared towards a better functional recovery., (Copyright © 2011 Elsevier B.V.

Patients' views of inpatient care need to be assessed for research and routine evaluation. For this a valid instrument is required. The Client Assessment of Treatment Scale (CAT) has been used in large scale international studies, but its psychometric properties have not been well established. The structural validity of the CAT was tested among involuntary inpatients with psychosis. Data from locations in three separate European countries (England, Spain and Bulgaria) were collected. The factorial validity was initially tested using single sample confirmatory factor analyses in each country. Subsequent multi-sample analyses were used to test for invariance of the factor loadings, and factor variances across the countries. Results provide good initial support for the factorial validity and invariance of the CAT scores. Future research is needed to cross-validate these findings and to generalise them to other countries, treatment settings, and patient populations., (Copyright © 2011 Elsevier Ltd.

Objective: To examine existential questions in the daily life of people with schizophrenia and their caregivers., Methods: Qualitative study with focus groups. 146 people with schizophrenia (55% men) and 80 caregivers (75% women) participated. They came predominantly from primary and secondary health services of Argentina, Brazil, Chile, Spain, England and Venezuela. Each group had between six and ten participants. The data was explored through a content analysis process., Results: Four omnipresent existential themes were identified from the discussions: the need for personal development and to find meaning in life; the need to be respected and not suffer discrimination or stigma; the conflict resulting from the loss of autonomy; the importance of understanding the illness and recognizing it as an illness. The existential questions were closely associated with objective needs, such as the lack of occupational opportunities and employment, which generally result in a life without meaning., Conclusions: It is necessary to develop a new type of health care in which both the consideration for the person with schizophrenia and their subjectivity are as important as biological treatment. Health promotion strategies need to combat stigma and use mechanisms of occupational inclusion.

The current study aims to discover the opinions of patients and their (informal and formal) carers concerning the mental health care of individuals with long term schizophrenic disorders within different contexts and cultures. It's a qualitative study with focus groups,in which 6 research centers (from Argentina, Brazil, Chile, Spain, England and Venezuela) participated. Eight focus groups were conducted in each center, totaling 303 individuals in 46 groups. The data were analyzed with the aid of the Qualitative Solutions and Research/Non-numerical Unstructured Data Indexing program (QSR NUD*IST 4.0). The perception regarding the quality of care is influenced by the professional-patient relationship and the availability of resources. Poor quality of care is also perceived as discrimination. People with schizophrenia in general consider themselves to be ostracized by professionals and services and lacking in more humanized care. In the contexts in which community care is less advanced, the complaints center on resources and services that do not meet demands. On the other hand, in more developed contexts criticism centers more on the attitude of the professionals and the professional patient relationship. Over and above the need for resources and services, people with schizophrenia require more humanized health care.

Introduction: Coerced admission to psychiatric hospitals, defined by legal status or patient's subjective experience, is common. Evidence on clinical outcomes however is limited. This study aimed to assess symptom change over a three month period following coerced admission and identify patient characteristics associated with outcomes., Method: At study sites in 11 European countries consecutive legally involuntary patients and patients with a legally voluntary admission who however felt coerced, were recruited and assessed by independent researchers within the first week after admission. Symptoms were assessed on the Brief Psychiatric Rating Scale. Patients were re-assessed after one and three months., Results: The total sample consisted of 2326 legally coerced patients and 764 patients with a legally voluntary admission who felt coerced. Symptom levels significantly improved over time. In a multivariable analysis, higher baseline symptoms, being unemployed, living alone, repeated hospitalisation, being legally a voluntary patient but feeling coerced, and being initially less satisfied with treatment were all associated with less symptom improvement after one month and, other than initial treatment satisfaction, also after three months. The diagnostic group was not linked with outcomes., Discussion: On average patients show significant but limited symptom improvements after coerced hospital admission, possibly reflecting the severity of the underlying illnesses. Social factors, but not the psychiatric diagnosis, appear important predictors of outcomes. Legally voluntary patients who feel coerced may have a poorer prognosis than legally involuntary patients and deserve attention in research and clinical practice.

Background: Few data exist on the psychosocial factors associated with attrition in longitudinal surveys. This study was undertaken to determine psychosocial and sociodemographic predictors of attrition from a longitudinal study of the onset and persistence of episodes of major depression in primary care., Methods: A systematic random sample of general practice attendees was recruited in seven Spanish provinces between October 2005 and February 2006. Major depression was diagnosed using the Composite International Diagnostic Interview and a set of 39 individual and environmental risk factors for depression were assessed at baseline and after 6 and 12 months of follow-up. Data were analysed using multilevel logistic regression., Results: 7777 primary care attendees aged 18-75 years were selected, of whom 1251 (16.1%) were excluded. Of the remaining 6526, 1084 (16.6%) refused to participate. Thus, 5442 patients (attending 231 family physicians in 41 health centres) were interviewed at baseline, of whom 3804 (70%) and 3567 (66%) remained at 6 and 12 months of follow-up, respectively. The province and sociodemographic factors were stronger predictors of attrition than psychosocial factors. Depression and anxiety had no effect but other psychosocial factors affected attrition. There were different profiles for the patients lost at 12 months when predictors measured at baseline versus 6 months were included., Conclusions: These findings suggest that several psychosocial factors might be considered factors of attrition in primary care cohorts and confirm that baseline characteristics are insufficient for analysing non-response in longitudinal studies, indicating that different retention strategies should be applied for patients interviewed at 6 and 12 months.

Background: Legislation and practice of involuntary hospital admission vary substantially among European countries, but differences in outcomes have not been studied., Aims: To explore patients' views following involuntary hospitalisation in different European countries., Method: In a prospective study in 11 countries, 2326 consecutive involuntary patients admitted to psychiatric hospital departments were interviewed within 1 week of admission; 1809 were followed up 1 month and 1613 3 months later. Patients' views as to whether the admission was right were the outcome criterion., Results: In the different countries, between 39 and 71% felt the admission was right after 1 month, and between 46 and 86% after 3 months. Females, those living alone and those with a diagnosis of schizophrenia had more negative views. Adjusting for confounding factors, differences between countries were significant., Conclusions: International differences in legislation and practice may be relevant to outcomes and inform improvements in policies, particularly in countries with poorer outcomes.

Background: Factors associated with depression are usually identified from cross-sectional studies., Aims: We explore the relative roles of onset and recovery in determining these associations., Method: Hazard ratios for onset and recovery were estimated for 39 risk factors from a cohort study of 10,045 general practice attendees whose depression status was assessed at baseline, 6 and 12 months., Results: Risk factors have a stronger relative effect on the rate of onset than recovery. The strongest risk factors for both onset and maintenance of depression tend to be time-dependent. With the exception of female gender the strength of a risk factor's effect on onset is highly predictive of its impact on recovery., Conclusions: Preventive measures will achieve a greater reduction in the prevalence of depression than measures designed to eliminate risk factors post onset. The strength of time-dependent risk factors suggests that it is more productive to focus on proximal rather than distal factors.

Studies on the association between the functional uMAOA polymorphism and depression have yielded non-conclusive results up till now. One thousand two hundred twenty eight consecutive Spanish primary care attendees, participating in the PREDICT study, agreed to take part in this genetic PREDICT-Gene study. We explored the association between depression and either high-activity uMAOA alleles or genotypes. Depression was diagnosed using the Composite International Diagnostic Interview (CIDI) to establish three different depressive outcomes (ICD-10 Depressive Episode (DE), ICD-10 Severe Depressive Episode (SDE) and DSM-IV Major Depression (MD)). uMAOA genetic variation was determined by PCR amplification and subsequent electrophoresis. Crude and adjusted (gender and/or age) odds ratios, with 95% confidence intervals, were calculated for the associations between allele or genotype frequencies and all three depressive outcomes. We found associations between all three depressive phenotypes and either high-activity alleles or high-activity genotypes in both sexes. The associations were statistically significant for females but not for males. Testing the same associations on the entire sample (males and females) also yielded significant associations between depression and either high-activity alleles or high-activity genotype distribution that were independent of age and/or gender (ICD-10 DE: OR = 1.98; 95% CI: 1.42-1.77; P = 0.00002; ICD-10-SDE: OR = 2.05; 95% CI: 1.38-3.05; P = 0.0002; DSM-IV MD: OR = 1.91; 95% CI: (1.26-2.91); P = 0.0014). Our results provide fairly consistent evidence that high-activity variants of the MAOA promoter polymorphism confer a modestly higher risk for depression., ((c) 2008 Wiley-Liss, Inc.)

Background: The effects of putative risk factors on the onset and/or persistence of depression remain unclear. We aim to develop comprehensive models to predict the onset and persistence of episodes of depression in primary care. Here we explain the general methodology of the predictD-Spain study and evaluate the reliability of the questionnaires used., Methods: This is a prospective cohort study. A systematic random sample of general practice attendees aged 18 to 75 has been recruited in seven Spanish provinces. Depression is being measured with the CIDI at baseline, and at 6, 12, 24 and 36 months. A set of individual, environmental, genetic, professional and organizational risk factors are to be assessed at each follow-up point. In a separate reliability study, a proportional random sample of 401 participants completed the test-retest (251 researcher-administered and 150 self-administered) between October 2005 and February 2006. We have also checked 118,398 items for data entry from a random sample of 480 patients stratified by province., Results: All items and questionnaires had good test-retest reliability for both methods of administration, except for the use of recreational drugs over the previous six months. Cronbach's alphas were good and their factorial analyses coherent for the three scales evaluated (social support from family and friends, dissatisfaction with paid work, and dissatisfaction with unpaid work). There were 191 (0.16%) data entry errors., Conclusion: The items and questionnaires were reliable and data quality control was excellent. When we eventually obtain our risk index for the onset and persistence of depression, we will be able to determine the individual risk of each patient evaluated in primary health care.
