The European Study of the Epidemiology of Mental Disorders (ESEMeD/MHEDEA 2000) project: rationale and methods

Self-reporting of psychiatric illness in an online patient registry is a good indicator of the existence of psychiatric illness

Online registries offer many advantages for research, including the ability to efficiently assess large numbers of individuals and identify potential participants for clinical trials and genetic studies. Of particular interest is the validity and utility of self-endorsement of psychiatric disorders in online registries, which, while increasingly more common, remain understudied. We thus assessed the comparability of prevalence estimated from self-endorsement of psychiatric disorders in one such registry, the Brain Health Registry (BHR) to prevalence computed from large US-based epidemiological studies and the degree to which BHR participants report psychiatric disorders consistently. We also examined the concordance between self-report and clinically determined diagnoses of various DSM-5 psychiatric disorders in a subset of participants who underwent direct assessments and identified possible reasons for discordance. Rates of self-reported psychiatric disorders were closest to previously reported population prevalence rates when endorsed at multiple timepoints, and accuracy was at least 70% for all except Hoarding Disorder as compared to the clinical diagnoses. Clinical data suggested that self-endorsement of a given psychiatric diagnosis was indicative of the presence of a closely related condition, although not necessarily for the specific disorder, with the exception of major depressive disorder, panic disorder, and hoarding disorder, which had high positive predictive values (85%, 73%, 100%, respectively). We conclude that self-reporting of psychiatric conditions in an online setting is a fair indicator of psychopathology, but should be accompanied by more in-depth interviews if using data from a participant for a specific disorder.

Gender Differences in the Prevalence of Mental Health, Psychological Distress and Psychotropic Medication Consumption in Spain: A Nationwide Population-Based Study

BACKGROUND

To assess gender differences in the prevalence of self-reported mental disorders, psychological distress and psychotropic drug consumption, and to identify sociodemographic and health-related variables associated with these conditions in the male and female population (aged ≥ 18 years).

METHODS

A cross-sectional study was carried on 22,141 subjects aged 18 and over, using data from the Spanish National Health Interview Survey 2017.

RESULTS

We found an overall prevalence of mental disorders, psychological distress and psychotropic drug consumption of 13.8%, 18.3% and 13.9%, respectively. After multivariable adjustment, women showed significantly increased probabilities of 1.74-fold for mental disorders, 1.26-fold for psychological distress and 1.26-fold for psychotropic drug consumption compared to men. Variables such as gender, age, nationality, marital status, educational level, self-rated health, the presence of different chronic disorders, alcohol consumption and smoking habit were independently associated with mental disorders, psychological distress and psychotropic drug consumption. Several variables showed a differential effect on mental health status and psychotropic drug consumption according to gender.

CONCLUSIONS

Women suffer from mental disorders, experience psychological distress and consume psychotropic drugs significantly more than men in Spain. Possible explanations for these results may be related to differences in emotional processing, willingness to report diseases and even intrinsic biological traits. Screening for mental health status and psychotropic drug consumption should be considered, particularly in Spanish women, younger adults and individuals who are not married, are obese, have poor self-rated health, suffer from chronic diseases or have a smoking habit.

Post-traumatic stress burden in a sample of hospitalized patients with Bipolar Disorder: Which impact on clinical correlates and suicidal risk?

BACKGROUND

Increasing evidence suggests Bipolar Disorder (BD) to be frequently associated to a history of traumatic experiences and Post-traumatic Stress Disorder (PTSD), with consequent greater symptoms severity, number of hospitalizations and worsening in quality of life. The aim of the present study was to investigate the lifetime exposure to traumatic events and PTSD rates in-patients with BD and to analyze the relationships between PTSD symptoms, clinical characteristics and severity of the mood disorder.

METHODS

A consecutive sample of 212 in-patients with a DSM-5 diagnosis of BD was enrolled at the psychiatric unit of a major University hospital in Italy and assessed by the SCID-5 and MOOD Spectrum-Self Report lifetime version (MOODS-SR). Socio-demographic characteristics, clinical features, substance or alcohol abuse, history of suicide related behaviors were also collected.

RESULTS

Lifetime trauma exposure emerged in 72.3% subjects, with a DSM-5 PTSD diagnosis reported by 35.6%. Patients with PTSD showed more frequently a (hypo)manic episode at onset, alcohol or substance abuse, psychotic features, suicide behaviors, higher scores in almost all the MOODS-SR domains, compared to those without PTSD.

LIMITATIONS

Cross sectional study. Lack of data about the time since trauma exposure or PTSD onset.

CONCLUSIONS

Our findings show a history of multiple traumatic experiences in hospitalized patients with BD besides high rates of PTSD, with the co-occurrence of these conditions appearing to be related to a more severe BD. Detailed investigation of post-traumatic stress symptoms is recommended for the relevant implications on the choice of a tailored treatment and the prognosis assessment.

[Use of psychotherapy among adults with a history of suicide attempt: Results form a large population-based study]

OBJECTIVES

The current study aims to identify the factors associated with the use of psychotherapy among adults with a history of suicide attempt.

METHODS

A large cross-sectional survey (N=22,138) was conducted in four regions of France to characterize mental health care needs in the general population. Data were collected between April and June 2005 by trained interviewers using a computer-assisted telephone interviewing system (CATI). Sociodemographics, past-year mental disorders, lifetime and 12-month history of suicide attempts, and use of psychotherapy were assessed.

RESULTS

Overall, 7.1% of adults reported having undergone psychotherapy in the course of their life, and 2.0% in the previous 12 months. While 8.3% of adults with a lifetime suicide attempt (prior to the previous 12 months) underwent a psychotherapy in the previous 12 months, 27.5% of adults with a past-year suicide attempt underwent a psychotherapy in the previous 12 months. Psychotherapy was provided by psychiatrists (49.5%), psychologists (28.2%), and psychoanalysts (10.6%). While the frequency of psychotherapy sessions was greater among those with a prior attempt as compared to those with no prior attempt [Chi² (10)=21.35, P=.019], there was no difference in therapy duration [Chi² (8)=6.71, P=.568]. Compared to adults who did not report a prior attempt, those with a prior suicide attempt were 3,3 more likely to undergo psychotherapy with a psychologist [AOR=3.31 (2.54-4.31)]. Among adults with a prior suicide attempt, increased odds of undergoing a psychotherapy in the course of their life was predicted by higher education [AOR=2.81 (1.56-5.06)], living in the Paris region [AOR=2.06 (1.32-3.23)], and being a woman [AOR=1.50 (1.08-2.09)]. Increased odds of undergoing a psychotherapy in the previous 12 months was predicted by a major depressive disorder [AOR=2.59 (1.57-4.27)], any anxiety disorder [AOR=1.79 (1.07-2.97)], higher education [AOR=3.60 (1.29-10.0)], living in a city of 20,000 to 100,000 inhabitants [AOR=2.71 (1.13-6.50)] and more [AOR=2.50 (1.12-5.57)] (outside of the Paris region), a 2000 to 3000 euros monthly income [AOR=2.37 (1.15-4.85)].

DISCUSSION

One third of adults with a lifetime suicide attempt and close to half of those with a past-year attempt have received some form of psychotherapy in the course of their life. In line with prior work, higher education and income level predicted past-year use of psychotherapy among adults with a prior suicide attempt. These findings highlight the association between major depressive disorder or anxiety disorders and increased odds of undergoing psychotherapy in the previous 12 months among adults with prior attempt. While pharmacological treatment, inpatient hospitalizations for mental health problems, visits with a general practitioner or specialized physician are free of charge in France, psychotherapy provided by psychologists or psychotherapists is currently not covered by the French Social Security health care system. As the treatment of mental disorders plays an important role in the reduction of suicide risk, supporting evidence-based psychotherapy through its reimbursement appears to be an important public health issue.

Study approach and field work procedures of the MentDis_ICF65+ project on the prevalence of mental disorders in the older adult European population

BACKGROUND

This study describes the study approach and field procedures of the MentDis_ICF65+ study, which aims to assess the prevalence of mental disorders in older adults.

METHODS

An age-appropriate version of the Composite International Diagnostic Interview (CIDI65+) was developed and tested with regard to its feasibility and psychometric properties in a pre-test and pilot phase. In the cross-sectional survey an age-stratified, random sample of older adults (65-84 years) living in selected catchment areas of five European countries and Israel was recruited.

RESULTS

N = 3142 participants (mean age 73.7 years, 50.7% female) took part in face-to-face interviews. The mean response rate was 20% and varied significantly between centres, age and gender groups. Sociodemographic differences between the study centres appeared for the place of birth, number of grandchildren, close significants, retirement and self-rated financial situation. The comparison of the MentDis_ICF65+ sample with the catchment area and country population of the study centres revealed significant differences, although most of these were numerically small.

CONCLUSIONS

The study will generate new information on the prevalence of common mental disorders among older adults across Europe using an age-appropriate, standardized diagnostic instrument and a harmonized approach to sampling. Generalizability of the findings and a potentially limited representativeness are discussed.

The Saudi National Mental Health Survey: Methodological and logistical challenges from the pilot study

Several challenges exist in carrying out nation-wide epidemiological surveys in the Kingdom of Saudi Arabia (KSA) due to the unique characteristics of its population. The objectives of this report are to review these challenges and the lessons learnt about best practices in meeting these challenges from the extensive piloting of the Saudi National Mental Health Survey (SNMHS), which is being carried out as part of the World Mental Health (WMH) Survey Initiative. We focus on challenges involving sample design, instrumentation, and data collection procedures. The SNMHS will ultimately provide crucial data for health policy-makers and mental health specialists in KSA.

Baclofen to prevent agitation in alcohol-addicted patients in the ICU: study protocol for a randomised controlled trial

Background

Alcohol is the leading psychoactive substance consumed in France, with about 15 million regular consumers. The National institute on Alcohol Abuse and Alcoholism (NIAAA) considers alcohol abuse to be more than 14 units of alcohol a week for men and 7 units for women. The specific complication of alcoholism is the alcohol withdrawal syndrome. Its incidence reaches up to 30 % and its main complications are delirium tremens, restlessness, extended hospital stay, higher morbidity, and psychiatric and cognitive impairment. Without appropriate treatment, delirium tremens can lead to death in up to 50 % of patients.

Methods/design

This prospective, double-blind, randomised controlled study versus placebo will be conducted in twelve French intensive care units (ICU). Patients with an alcohol intake level higher than the NIAAA threshold, who are under mechanical ventilation, will be included. The primary objective is to determine whether baclofen is more efficient than placebo in preventing restlessness-related side effects in the ICU. Secondary outcomes include mechanical ventilation duration, length of ICU stay, and cumulative doses of sedatives and painkillers received within 28 days of ICU admission. Restlessness-related side effects in the ICU are defined as unplanned extubation, medical disposal removal (such as urinary catheter, venous or arterial line or surgical drain), falling out of bed, ICU runaway (leaving ICU without physician's approval), immobilisation device removal, self-aggression or aggression towards medical staff. Daily doses of baclofen/placebo will be guided by daily creatinine clearance assessment.

Discussion

Restlessness in alcoholic patients is a life-threatening issue in ICUs. BACLOREA is a randomised study assessing the capacity of baclofen to prevent agitation in mechanically ventilated patients. Enrolment of 314 patients will begin in June 2016 and is expected to end in October 2018.

Suicidality and its relationship with depression, alcohol disorders and childhood experiences of violence: results from the ESEMeD study

BACKGROUND

Suicidality constitutes a major health concern in many countries. The aim of the present paper was to analyse 10 of its risk factors and their interdependence.

METHODS

Data on suicidality, mental disorders and experience of childhood violence was collected from 8796 respondents in the European Study of the Epidemiology of Mental Disorders (ESEMeD). The CIDI was used to assess mental disorders. Individuals were randomly divided into two subgroups. In one, a Graphical Markov model to predict suicidality was constructed, in the second, predictors were cross-validated.

RESULTS

Lifetime suicidality was predicted mainly by lifetime depression and early experiences of violence, with a pseudo R-square of 12.8%. In addition, alcohol disorders predicted suicidality, but played a minor role compared with the other risk factors in this sample.

CONCLUSION

In addition to depression, early experience of violence constitutes an important risk factor of suicidality.

LIMITATIONS

This is a cross-sectional and retrospective study assessing risk factors for suicidality, not for suicide itself.

Frequency of trauma exposure and Post-Traumatic Stress Disorder in Italy: analysis from the World Mental Health Survey Initiative

Epidemiological studies have examined the relative importance of Traumatic Events (TEs) in accounting for the societal burden of post-traumatic stress disorder (PTSD). However, most studies used the worst trauma experienced, which can lead to an overestimation of the conditional risk of PTSD. Although a number of epidemiological surveys on PTSD have been carried out in the United States, only a few studies in limited sample have been conducted in Italy. This study, carried out in the framework of the World Mental Health Survey Initiative, is a cross-sectional household survey of a representative sample of the Italian adult population. Lifetime prevalence of TEs and 12-month prevalence of PTSD were evaluated using the Composite International Diagnostic Interview (CIDI). Reports of PTSD associated with randomly selected TEs were weighted by the individual-level probabilities of TE selection to generate estimates of population-level PTSD risk associated with each TE. Network events was the most commonly reported class of TEs (29.4%). War events had the highest conditional risk of PTSD (12.2%). The TEs that contributed most to societal PTSD burden were unexpected death of a loved one (24.1%) and having seen atrocities (18.2%). Being female was related to high risk of PTSD after experiencing a TE. Exposure to network events is commonly reported among Italian adults, but two TEs are responsible for the highest burden associated with PTSD: the unexpected death of someone close and sexual assault. These results can help designing public health interventions to reduce the societal PTSD burden.

Epidemiology and genetics of common mental disorders in the general population: the PEGASUS-Murcia project

BACKGROUND

Multidisciplinary collaboration between clinicians, epidemiologists, neurogeneticists and statisticians on research projects has been encouraged to improve our knowledge of the complex mechanisms underlying the aetiology and burden of mental disorders. The PEGASUS-Murcia (Psychiatric Enquiry to General Population in Southeast Spain-Murcia) project was designed to assess the prevalence of common mental disorders and to identify the risk and protective factors, and it also included the collection of biological samples to study the gene-environmental interactions in the context of the World Mental Health Survey Initiative.

METHODS AND ANALYSIS

The PEGASUS-Murcia project is a new cross-sectional face-to-face interview survey based on a representative sample of non-institutionalised adults in the Region of Murcia (Mediterranean Southeast, Spain). Trained lay interviewers used the latest version of the computer-assisted personal interview of the Composite International Diagnostic Interview (CIDI 3.0) for use in Spain, specifically adapted for the project. Two biological samples of buccal mucosal epithelium will be collected from each interviewed participant, one for DNA extraction for genomic and epigenomic analyses and the other to obtain mRNA for gene expression quantification. Several quality control procedures will be implemented to assure the highest reliability and validity of the data. This article describes the rationale, sampling methods and questionnaire content as well as the laboratory methodology.

ETHICS AND DISSEMINATION

Informed consent will be obtained from all participants and a Regional Ethics Research Committee has approved the protocol. Results will be disseminated in peer-reviewed publications and presented at the national and the international conferences.

DISCUSSION

Cross-sectional studies, which combine detailed personal information with biological data, offer new and exciting opportunities to study the gene-environmental interactions in the aetiology of common mental disorders in representative samples of the general population. A collaborative multidisciplinary research approach offers the potential to advance our knowledge of the underlying complex interactions and this opens the field for further innovative study designs in psychiatric epidemiology.

Use of general practitioners versus mental health professionals in six European countries: the decisive role of the organization of mental health-care systems

OBJECTIVE

To investigate patterns of use of general practitioners (GPs) and/or mental health professionals (MHPs) for mental health reasons, across six European countries, and the extent to which these patterns of use are associated with differences in mental health-care delivering systems.

METHODS

Data are based on the European Study of the Epidemiology of Mental Disorders (ESEMeD): a cross-sectional survey of a representative sample of 8,796 non-institutionalized adults from six European countries, conducted between 2001 and 2003 using computer-assisted interviews with the CIDI-3.0. Countries were classified into: MHP- for countries where access to medical professionals tends to predominate (Belgium, France, Italy), and MHP+ where access to non-medical MHPs predominates (Germany, Spain, The Netherlands).

RESULTS

Among respondents consulting GPs and/or MHPs in the past year (n = 1,019), respondents from the MHP- group more often consulted GPs (68 vs. 55 % in MHP+ group), GPs and psychiatrists (23 vs. 14 %). People from the MHP+ group more often used MHPs only (45 vs. 32 %), GPs and non-medical MHPs (16 vs. 8 %). GPs from the MHP+ group were more inclined to refer patients to MHPs. Factors associated with use of GPs versus MHPs were: being over 49 years, not highly educated, lower income and suffering from mood or severe mental disorders.

CONCLUSIONS

Differences in the use of GPs versus MHPs are markedly linked to individual as well as organizational factors. Interventions are needed, in countries fostering medical access, to reimburse sessions with non-medical MHPs and improve cooperation between professionals to obtain better practice in access to care.

Cultural adaptation of the Latin American version of the World Health Organization Composite International Diagnostic Interview (WHO-CIDI) (v 3.0) for use in Spain

OBJECTIVE

To develop a Spanish version of the WHO-Composite International Diagnostic Interview (WHO-CIDI) applicable to Spain, through cultural adaptation of its most recent Latin American (LA v 20.0) version.

METHODS

A 1-week training course on the WHO-CIDI was provided by certified trainers. An expert panel reviewed the LA version, identified words or expressions that needed to be adapted to the cultural or linguistic norms for Spain, and proposed alternative expressions that were agreed on through consensus. The entire process was supervised and approved by a member of the WHO-CIDI Editorial Committee. The changes were incorporated into a Computer Assisted Personal Interview (CAPI) format and the feasibility and administration time were pilot tested in a convenience sample of 32 volunteers.

RESULTS

A total of 372 questions were slightly modified (almost 7% of approximately 5000 questions in the survey) and incorporated into the CAPI version of the WHO-CIDI. Most of the changes were minor - but important - linguistic adaptations, and others were related to specific Spanish institutions and currency. In the pilot study, the instrument's mean completion administration time was 2h and 10min, with an interquartile range from 1.5 to nearly 3h. All the changes made were tested and officially approved.

CONCLUSIONS

The Latin American version of the WHO-CIDI was successfully adapted and pilot-tested in its computerized format and is now ready for use in Spain.

Benzodiazepines revisited--will we ever learn?

AIMS

To re-examine various aspects of the benzodiazepines (BZDs), widely prescribed for 50 years, mainly to treat anxiety and insomnia. It is a descriptive review based on the Okey Lecture delivered at the Institute of Psychiatry, King's College London, in November 2010.

METHODS

A search of the literature was carried out in the Medline, Embase and Cochrane Collaboration databases, using the codeword 'benzodiazepine(s)', alone and in conjunction with various terms such as 'dependence', 'abuse', etc. Further hand-searches were made based on the reference lists of key papers. As 60,000 references were found, this review is not exhaustive. It concentrates on the adverse effects, dependence and abuse.

RESULTS

Almost from their introduction the BZDs have been controversial, with polarized opinions, advocates pointing out their efficacy, tolerability and patient acceptability, opponents deprecating their adverse effects, dependence and abuse liability. More recently, the advent of alternative and usually safer medications has opened up the debate. The review noted a series of adverse effects that continued to cause concern, such as cognitive and psychomotor impairment. In addition, dependence and abuse remain as serious problems. Despite warnings and guidelines, usage of these drugs remains at a high level. The limitations in their use both as choice of therapy and with respect to conservative dosage and duration of use are highlighted. The distinction between low-dose 'iatrogenic' dependence and high-dose abuse/misuse is emphasized.

CONCLUSIONS

The practical problems with the benzodiazepines have persisted for 50 years, but have been ignored by many practitioners and almost all official bodies. The risk-benefit ratio of the benzodiazepines remains positive in most patients in the short term (2-4 weeks) but is unestablished beyond that time, due mainly to the difficulty in preventing short-term use from extending indefinitely with the risk of dependence. Other research issues include the possibility of long-term brain changes and evaluating the role of the benzodiazepine antagonist, flumazenil, in aiding withdrawal.

The size and burden of mental disorders and other disorders of the brain in Europe 2010

AIMS

To provide 12-month prevalence and disability burden estimates of a broad range of mental and neurological disorders in the European Union (EU) and to compare these findings to previous estimates. Referring to our previous 2005 review, improved up-to-date data for the enlarged EU on a broader range of disorders than previously covered are needed for basic, clinical and public health research and policy decisions and to inform about the estimated number of persons affected in the EU.

METHOD

Stepwise multi-method approach, consisting of systematic literature reviews, reanalyses of existing data sets, national surveys and expert consultations. Studies and data from all member states of the European Union (EU-27) plus Switzerland, Iceland and Norway were included. Supplementary information about neurological disorders is provided, although methodological constraints prohibited the derivation of overall prevalence estimates for mental and neurological disorders. Disease burden was measured by disability adjusted life years (DALY).

RESULTS

Prevalence: It is estimated that each year 38.2% of the EU population suffers from a mental disorder. Adjusted for age and comorbidity, this corresponds to 164.8million persons affected. Compared to 2005 (27.4%) this higher estimate is entirely due to the inclusion of 14 new disorders also covering childhood/adolescence as well as the elderly. The estimated higher number of persons affected (2011: 165m vs. 2005: 82m) is due to coverage of childhood and old age populations, new disorders and of new EU membership states. The most frequent disorders are anxiety disorders (14.0%), insomnia (7.0%), major depression (6.9%), somatoform (6.3%), alcohol and drug dependence (>4%), ADHD (5%) in the young, and dementia (1-30%, depending on age). Except for substance use disorders and mental retardation, there were no substantial cultural or country variations. Although many sources, including national health insurance programs, reveal increases in sick leave, early retirement and treatment rates due to mental disorders, rates in the community have not increased with a few exceptions (i.e. dementia). There were also no consistent indications of improvements with regard to low treatment rates, delayed treatment provision and grossly inadequate treatment. Disability: Disorders of the brain and mental disorders in particular, contribute 26.6% of the total all cause burden, thus a greater proportion as compared to other regions of the world. The rank order of the most disabling diseases differs markedly by gender and age group; overall, the four most disabling single conditions were: depression, dementias, alcohol use disorders and stroke.

CONCLUSION

In every year over a third of the total EU population suffers from mental disorders. The true size of "disorders of the brain" including neurological disorders is even considerably larger. Disorders of the brain are the largest contributor to the all cause morbidity burden as measured by DALY in the EU. No indications for increasing overall rates of mental disorders were found nor of improved care and treatment since 2005; less than one third of all cases receive any treatment, suggesting a considerable level of unmet needs. We conclude that the true size and burden of disorders of the brain in the EU was significantly underestimated in the past. Concerted priority action is needed at all levels, including substantially increased funding for basic, clinical and public health research in order to identify better strategies for improved prevention and treatment for disorders of the brain as the core health challenge of the 21st century.

Measurement and description of underlying dimensions of comorbid mental disorders using Factor Mixture Models: results of the ESEMeD project

Epidemiological studies on mental health and mental comorbidity are usually based on prevalences and correlations between disorders, or some other form of bivariate clustering of disorders. In this paper, we propose a Factor Mixture Model (FMM) methodology based on conceptual models aiming to measure and summarize distinctive disorder information in the internalizing and externalizing dimensions. This methodology includes explicit modelling of subpopulations with and without 12 month disorders ("ill" and "healthy") by means of latent classes, as well as assessment of model invariance and estimation of dimensional scores. We applied this methodology with an internalizing/externalizing two-factor model, to a representative sample gathered in the European Study of the Epidemiology of Mental Disorders (ESEMeD) study -- which includes 8796 individuals from six countries, and used the CIDI 3.0 instrument for disorder assessment. Results revealed that southern European countries have significantly higher mental health levels concerning internalizing/externalizing disorders than central countries; males suffered more externalizing disorders than women did, and conversely, internalizing disorders were more frequent in women. Differences in mental-health level between socio-demographic groups were due to different proportions of healthy and ill individuals and, noticeably, to the ameliorating influence of marital status on severity. An advantage of latent model-based scores is that the inclusion of additional mental-health dimensional information -- other than diagnostic data -- allows for greater precision within a target range of scores.

Functional disability as an explanation of the associations between chronic physical conditions and 12-month major depressive episode

BACKGROUND

The link between physical conditions and mental health is poorly understood. Functional disability could explain the association of physical conditions with major depressive episode (MDE) as an intermediary factor.

METHODS

Data was analyzed from a subsample (N=8796) of the European Study of the Epidemiology of Mental Disorders (ESEMeD), a cross-sectional general population survey. MDE during the last 12 months was assessed using a revision of the Composite International Diagnostic Interview (CIDI 3.0). Lifetime chronic physical conditions were assessed by self-report. Functional disability was measured using a version of the World Health Organization Disability Assessment Schedule (WHODAS). The associations of physical conditions with MDE and explanation by functional disability were quantified using logistic regression.

RESULTS

All physical conditions were significantly associated with MDE. The increases in risk of MDE ranged from 30% for allergy to amply 100% for arthritis and heart disease. When adjusted for physical comorbidity, associations decreased and were no longer statistically significant for allergy and diabetes. Functional disability explained between 17 and 64% of these associations, most substantially for stomach or duodenum ulcer, arthritis and heart disease.

LIMITATIONS

Due to the cross-sectional nature of the study the temporal relationship of the variables could not be assessed and the amount of explanation cannot simply be interpreted as the amount of mediation.

CONCLUSIONS

Our findings suggest that the association of chronic physical conditions with MDE is partly explained by functional disability. Such explanation is more pronounced for pain causing conditions and heart disease. Health professionals should be particularly aware of the increased risk of depressive disorder when patients experience disability from these conditions.

Usage of benzodiazepines: A review

Abstract Purpose. The use of benzodiazepines remains a source of controversy. Some prescribers believe that they are beneficial and espouse their use; others regard their risk:benefit ratio as too adverse for any but occasional use. This review considers these viewpoints based on the appropriate literature. Survey. The recent English-language literature relating to this topic was surveyed. The publications proved too heterogeneous for a formal meta-analysis, so a descriptive review is provided. Overview. Surveys of benzodiazepine use provide data mainly from the UK, Europe and North America. Prescribing patterns varied widely but long-term usage is common and sometimes the norm. Conclusions. Long-term prescription of benzodiazepines still takes place despite general warnings from the medical and other professions and drug regulatory bodies that long-term use is unjustified both from the lack of a systemic database establishing such efficacy and a large literature documenting the risks of long-term usage, such as dependence. The young and the old are particularly at risk. Continued monitoring is essential, but the regulatory authorities may need to take a more active role in curbing such undesirable practice.

Comparing mental health of francophone populations in Canada, france, and belgium: 12-month prevalence rates of common mental disorders (part 1)

OBJECTIVE

To compare the 12-month prevalence of common mental disorders among francophones in Canada, France, and Belgium. This is the first article in a 2-part series comparing mental disorders and service use prevalence of French-speaking populations.

METHODS

This is a secondary analysis of data from the Canadian Community Health Survey: Mental Health and Well-Being (CCHS 1.2) in 2002 and the European Study of Epidemiology of Mental Disorders-Mental Health Disability (ESEMeD) from 2001 to 2003, where comparable questionnaires were administered to representative samples of adults in Canada, France, and Belgium. In Canada, francophone respondents living in Quebec (n = 7571) and outside Quebec (n = 500) completed the French version of the CCHS 1.2 questionnaire. Francophone respondents in Belgium (n = 389) and in France (n = 1436) completed the French version of the ESEMeD population survey questionnaire. Major depressive episodes (MDEs), specific anxiety disorders (ADs), and alcohol abuse and (or) dependence disorders' rates were assessed.

RESULTS

The overall prevalence rate for the presence of any MDE, AD, or alcohol abuse and (or) dependence was similar in all francophone populations studied in Canada and Europe and averaged 8.5%.

CONCLUSIONS

Mental disorders were equally distributed in all francophone populations studied. Cross-national comparisons continue to be instrumental in providing information useful for the creation of appropriate policies and programs for specific subsets of populations.

Comparing mental health of francophones in Canada, france, and belgium: 12-month and lifetime rates of mental health service use (part 2)

OBJECTIVES

To compare 12-month and lifetime service use for common mental disorders in 4 francophone subsamples using data from national mental health surveys in Canada, Quebec, France, and Belgium. This is the second article in a 2-part series comparing mental disorders and service use prevalence of French-speaking populations.

METHODS

Comparable World Mental Health-Composite International Diagnostic Interviews (WMH-CIDI) were administered to representative samples of adults (aged 18 years and older) in Canada during 2002 and in France and Belgium from 2001 to 2003. Two groups of francophone adults in Canada, in Quebec (n = 7571) and outside Quebec (n = 500), and respondents in Belgium (n = 389) and France (n = 1436) completed the French version of the population survey. Prevalence rates of common mental health service use were examined for major depressive episodes and specific anxiety disorders (that is, agoraphobia, social phobia, and panic disorder).

RESULTS

Overall, most francophones with mental disorders do not seek treatment. Canadians consulted more mental health professionals than their European counterparts, with the exception of psychiatrists.

CONCLUSIONS

Patterns of service use are similar among francophone populations. Variations that exist may be accounted for by differences in health care resources, health care systems, and health insurance coverage.

Evaluating the drug use "gateway" theory using cross-national data: consistency and associations of the order of initiation of drug use among participants in the WHO World Mental Health Surveys

BACKGROUND

It is unclear whether the normative sequence of drug use initiation, beginning with tobacco and alcohol, progressing to cannabis and then other illicit drugs, is due to causal effects of specific earlier drug use promoting progression, or to influences of other variables such as drug availability and attitudes. One way to investigate this is to see whether risk of later drug use in the sequence, conditional on use of drugs earlier in the sequence, changes according to time-space variation in use prevalence. We compared patterns and order of initiation of alcohol, tobacco, cannabis, and other illicit drug use across 17 countries with a wide range of drug use prevalence.

METHOD

Analyses used data from World Health Organization (WHO) World Mental Health (WMH) Surveys, a series of parallel community epidemiological surveys using the same instruments and field procedures carried out in 17 countries throughout the world.

RESULTS

Initiation of "gateway" substances (i.e. alcohol, tobacco and cannabis) was differentially associated with subsequent onset of other illicit drug use based on background prevalence of gateway substance use. Cross-country differences in substance use prevalence also corresponded to differences in the likelihood of individuals reporting a non-normative sequence of substance initiation.

CONCLUSION

These results suggest the "gateway" pattern at least partially reflects unmeasured common causes rather than causal effects of specific drugs on subsequent use of others. This implies that successful efforts to prevent use of specific "gateway" drugs may not in themselves lead to major reductions in the use of later drugs.

Treatment of major depressive disorder in the Finnish general population

BACKGROUND

Few general population studies of the treatment of major depressive disorder (MDD) have included the whole spectrum of treatments. We estimated the rates of different treatments and the effect of individual and disorder characteristics plus provider type on treatment received.

METHODS

In the Health 2000 Study, a representative sample (n=6,005) from the adult Finnish population (> or =30 years) were interviewed (CIDI) in 2000-2001 for the presence of DSM-IV mental disorders during the past 12 months. Logistic regression models were used to examine factors influencing the type of treatment: either pharmacotherapies (antidepressants, anxiolytics, sedatives/hypnotics, antipsychotics) or psychological treatment.

RESULTS

Of the individuals with MDD (n=288), currently 24% used antidepressants, 11% anxiolytics, 16% sedatives/hypnotics, 5% antipsychotics, and 17% reported having received psychological treatment. Overall, 31% received antidepressants or psychological treatment or both; 18% received minimally adequate treatment. Of those 33% (n=94) using health care services for mental reasons, 76% received antidepressants or psychological treatment or both; 54% received minimal adequate treatment. In logistic regression models, the use of antidepressants was associated with female sex, being single, severe MDD, perceived disability, and comorbid dysthymic disorder; psychological treatment with being divorced, perceived disability, and comorbid anxiety disorder.

CONCLUSIONS

Due to the low use of health services for mental reasons, only one-third of subjects with MDD use antidepressants, and less than one-fifth receives psychological treatment. The treatments provided are determined mostly by clinical factors such as severity and comorbidity, in part by sex and marital status, but not education or income.

Epidemiology of major depressive episode in a southern European country: results from the ESEMeD-Spain project

BACKGROUND

Information of the epidemiology of Major Depressive Episode (MDE) in Spain, one of the biggest southern European countries, is scarce and heterogeneous. The objective of this study was to assess the epidemiology of the disorder in the Spanish sample of the ESEMeD project.

METHODS

The ESEMED-Spain project is a cross-sectional, general population, household survey conducted with a representative sample of Spanish non-institutionalized adult population. The survey instrument was the CIDI 3.0, a structured diagnostic interview to assess disorders and treatment.

RESULTS

Lifetime prevalence was 10.6% while 12-month prevalence was 4.0%. A monotonic increase in lifetime overall prevalence was found from the youngest to the 50-64 cohort, declining then in the oldest group. Median age of onset was 30.0. Being a woman (OR=2.7), previously married (OR=1.8), unemployed or disabled to work (OR=2.9) was associated to higher risk of 12-month-MDE. The highest comorbid associations were with dysthymia (OR=73.1) and panic disorder (OR=41.8).

LIMITATIONS

1. Psychiatric diagnoses were made by trained lay interviewers and this could have an imperfect sensitivity/specificity; 2. Individuals with mental illness could have more frequently rejected to participate in the survey; 3. Age-related recall bias could have affected the accuracy of age of onset estimates.

CONCLUSIONS

The study shows that prevalence MDE in Spain is lower than in other Western countries. Important findings are the early age of onset, the high proportion of chronicity, and the high female/male ratio. Taken together, results offer a complex picture of the epidemiology of MDE in Spain, when compared to other countries in Europe. The role of cultural factors is discussed.

Is it always the same? Variability of depressive symptoms across six European countries

Using common diagnostic systems together with structured interviews to assess mental disorders has made it possible to compare diagnostic groups of mental disorders across countries. The implicit assumption is that the symptomatology of a particular disorder as defined by the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) will not vary between different countries. However, it is conceivable that there will be some variability in the symptom patterns. The present study examines if differences in depressive symptom patterns across European countries can be found and if there are different associations between symptoms and the latent construct depression. Data from 4025 individuals of the European Study of the Epidemiology of Mental Disorders (ESEMeD) project were analysed. Individuals were interviewed using the Composite International Diagnostic Interview (CIDI 3.0). Confirmatory factor analysis was used to examine the associations between depressive symptoms and the latent construct of depression in each country. The proportions of endorsed symptoms of depression showed only slight variation across European countries and only minor to moderate differences in the associations between depressive symptoms and the latent construct depression. The results demonstrated that in European countries using a fully structured and standardized interview based on European-American diagnostic concepts leads to similar results with regard to depressive symptom patterns.

Comparison of different valuation methods for population health status measured by the EQ-5D in three European countries

OBJECTIVE

The purpose of this study was to analyze and compare different valuation methods for population health status measured by the EuroQol-5D (EQ-5D) in three European countries.

METHODS

A representative survey of the noninstitutionalized population aged 18 and above was conducted in three European countries (Germany, The Netherlands, and Spain). A total of 11,932 respondents were interviewed using the EQ-5D self-classifier. Health state values based on community preferences (EQ-5D index) were calculated for each country using four different value sets: national value sets based on the time trade-off (TTO) and the visual analogue scale (VAS), the UK TTO-based value set and the European VAS-based value set. Linear regression analysis was conducted to evaluate the factors associated with different EQ-5D index scores depending on the value set used. Loss of quality-adjusted life-years (QALYs) was calculated for each country using the four value sets by multiplying the age and gender-specific values with the respective population size.

RESULTS

In all countries, means of all EQ-5D index scores were higher for men than women, and decreased with age. Index scores calculated using the national value set based on TTO were higher than those calculated using the UK TTO-based value set and, also, slightly higher than those calculated using the European VAS-based value set or the national value set based on the VAS. The mean loss of QALYs estimated for Germany per inhabitant varied between 0.062 (national value set based on TTO) and 0.094 (European VAS-based value set). In The Netherlands, the mean loss of QALYs per inhabitant ranged from 0.090 (national value set based on TTO) to 0.125 (national value set based on VAS). In Spain, the mean loss of QALYs per inhabitant ranged between 0.072 (national value set based on TTO) and 0.085 (European VAS-based value set).

CONCLUSIONS

In general, the differences among countries and valuations were rather small; nevertheless, some important variations should be taken into account while applying different valuation methods to the EQ-5D descriptive system. The associations between sociodemographic variables and health state scores remained the same across countries regardless of which value sets were used. Using different valuation methods lead to different QALY losses. To overcome this problem in international surveys aimed to compare health state scores or QALYs, it is advisable to use a single valuation method, making these scores comparable.

Mental disorders among persons with diabetes--results from the World Mental Health Surveys

OBJECTIVE

To estimate 12-month prevalence rate of mood, anxiety, and alcohol-use disorders among community samples of diabetic persons. We assess whether associations of specific mental disorders with diabetes are consistent across diverse countries after controlling for age and gender.

RESEARCH DESIGN AND METHODS

Eighteen surveys of household-residing adults were conducted in two phases across 17 countries in Europe, the Americas, the Middle East, Africa, Asia, and the South Pacific (Part 1, N=85,088). Mental disorders, identified by the World Mental Health-Composite International Diagnostic Interview, included anxiety disorders (generalized anxiety disorder, panic disorder/agoraphobia, posttraumatic stress disorder, and social phobia), mood disorders (dysthymia and major depressive disorder), and alcohol abuse/dependence. Diabetes was ascertained by self-report (Part 2, N=42,697). Association was assessed by age-gender adjusted odds ratios.

RESULTS

Risk of mood and anxiety disorders was slightly higher among persons with diabetes relative to those without: odds ratio of 1.38 for depression (95% CI=1.15-1.66) and 1.20 for anxiety disorders, (95 % CI=1.01-1.42), after adjusting for age and gender. Odds ratio estimates across countries did not differ more than chance expectation. Alcohol-use disorders were uncommon among persons with diabetes in most countries, and not associated with diabetes in pooled survey data.

CONCLUSIONS

Population sample surveys revealed mood and anxiety disorders occurred with somewhat greater frequency among persons with diabetes than those without diabetes. Prevalence of major depression among persons with diabetes was lower in the general population than suggested by prior studies of clinical samples. Strength of association did not differ significantly across disorders or countries.

Mediators of the association between depression and role functioning

OBJECTIVE

While the adverse effect of Major Depressive Episode on role functioning is well established, the exact pathways remain unclear.

METHOD

Data from The European Study of the Epidemiology of Mental Disorders, a cross-sectional survey including 21 425 adults from six European countries, were used to assess 12-month depression (Composite International Diagnostic Interview), activity limitations and role functioning in the past 30 days (Disability Assessment Schedule). An a priori model based on the World Health Organization's International Classification of Functioning, Disability and Health was designed and a structural equation model for categorical and ordinal data was used (MPlus) to estimate the extent to which six limitations mediated the association between depression and role functioning.

RESULTS

The unadjusted association between depression and role functioning was strong (0.43; SE = 0.04). In the best-fitting model, only concentration and attention problems and embarrassment mediated a significant amount of association (direct effect dropped to 0.17; SE = 0.10, which was no longer significant).

CONCLUSIONS

Targeting cognition and embarrassment in treatment could help reduce depression-associated role disfunctioning.

The relation between body mass index, mental health, and functional disability: a European population perspective

OBJECTIVE

To examine the association between body mass, mental disorders, and functional disability in the general population of 6 European countries.

METHOD

Data (n = 21 425) were derived from the European Study on the Epidemiology of Mental Disorders (ESEMeD). The third version of the Composite International Diagnostic Interview was administered to assess mental disorders (mood, anxiety, and alcohol disorders) according to the Diagnostic Statistical Manual of Mental Disorders-fourth edition, body mass index (BMI) (kg/m(2), based on self-reported height and weight), and functional disability in the previous 30 days, assessed with the World Health Organization Disablement Assessment Scale-second version.

RESULTS

About 3% of the respondents were underweight (BMI < 18.5 kg/m(2)), 53% had normal weight (BMI 18.5 to 24.9 kg/m(2)), 33% were overweight (BMI 25 to 29.9 kg/m(2)), and the remaining 12% met criteria for obesity (BMI >or= 30.0 kg/m(2)). Compared with individuals of normal weight, obese individuals were more likely to have mood (OR 1.3; 95%CI, 1.0 to 1.8) or more than one mental disorder (OR 1.4; 95%CI, 1.0 to 2.2). BMI had no impact on work loss days, whereas mental disorders had a considerable effect on work loss days.

CONCLUSIONS

This is the first cross-national study investigating the role between BMI, mental disorders, and functional disability in the general population. Being overweight or obese is a common condition in the 6 ESEMeD countries. Although there is a moderate association between obesity and mental disorders, BMI did not independently influence functional disability.

Clinical factors influencing the prescription of antidepressants and benzodiazepines: results from the European study of the epidemiology of mental disorders (ESEMeD)

OBJECTIVE

To examine factors associated with the use of antidepressants (AD) and benzodiazepines (BZD) in 6 European countries.

METHODS

A cross-sectional, population-based study was conducted in: Belgium, France, Germany, Italy, the Netherlands and Spain. 21,425 non-institutionalized individuals aged 18 years and over were interviewed using the third version of the Composite International Interview (CIDI-3.0). Respondents were asked about AD and BZD use, and whether they consulted formal health services for emotional problems in the previous year. Sociodemographic variables, presence of mood/anxiety disorders and of painful physical symptoms were collected.

RESULTS

34.38% and 9.17% of the sample reported the use of AD and BZD respectively in the previous 12 months. Only 29.95% of subjects with a 12-month prevalence of major depressive episode (MDE) had been taking antidepressants. After controlling for several clinical and non-clinical factors, help seeking for emotional problems was the most important independent predictor for the use of AD or BZD (OR: 13.58 and 5.17, respectively). Higher age was the second important predictor (OR: 6.52 and 4.86, respectively). A 12-month or lifetime prevalence of MDE or an anxiety disorder were also predictors for AD or BZD use (OR for MDE: 5.00 and 2.82, OR for anxiety disorders: 2.13 and 1.85). Finally, the presence of painful physical symptoms also predicted the use of AD and BZD, while female gender, lower education and higher age predicted only the use of BZD.

CONCLUSION

Less than one third of subjects with a 12-month prevalence of MDE had been taking antidepressants. But seeking help for emotional problems was a more important predictor of the use of ADs or BZDs than a formal (DSM-IV) psychiatric diagnosis, suggesting that usage of ADs is not always according to the licensed DSM-IV indication.

Comorbid painful physical symptoms and anxiety: prevalence, work loss and help-seeking

BACKGROUND

There is evidence that painful physical symptoms (PPS) are increased in patients with anxiety disorder (AD). This survey reports the 12-month prevalence and sociodemographic characteristics of PPS in subjects with and without AD, taking into account somatic comorbidity. In addition, the impact of PPS on work loss days (WLDs) and help-seeking was examined.

METHODS

In a cross-sectional, population-based study, a representative random sample of non-institutionalised adults from Belgium, France, Germany, Italy, The Netherlands and Spain (N=21,425) was interviewed using the World Mental Health Composite Diagnostic Interview (CIDI 3.0 of the WHO). 8296 respondents provided data on the occurrence of PPS, from which 5489 respondents reported the number of work loss days.

RESULTS

PPS were reported by 28% of respondents without AD and by 45% in those with AD. Female gender, higher age and lower educational level were predictive of PPS. No additive effect of AD and PPS was found on the WLD score, neither did the presence or not of a comorbid somatic disorder change the findings. Finally, respondents with both AD and PPS had numerically higher rates of help-seeking for emotional reasons (20.8% vs. 15.0% for respondents with AD but not PPS) and delayed their help-seeking for a numerically shorter period of time (289 vs. 413 days, respectively).

LIMITATIONS

The most important limitation of this study was its reliance on self-reported data about somatic disorders.

CONCLUSION

Approximately 45% of persons with anxiety disorder also reported the presence of PPS. No additive effect of AD and PPS was found on the WLD score, and the presence of PPS in AD does not delay help-seeking for emotional problems.

Toward a global view of alcohol, tobacco, cannabis, and cocaine use: findings from the WHO World Mental Health Surveys

BACKGROUND

Alcohol, tobacco, and illegal drug use cause considerable morbidity and mortality, but good cross-national epidemiological data are limited. This paper describes such data from the first 17 countries participating in the World Health Organization's (WHO's) World Mental Health (WMH) Survey Initiative.

METHODS AND FINDINGS

Household surveys with a combined sample size of 85,052 were carried out in the Americas (Colombia, Mexico, United States), Europe (Belgium, France, Germany, Italy, Netherlands, Spain, Ukraine), Middle East and Africa (Israel, Lebanon, Nigeria, South Africa), Asia (Japan, People's Republic of China), and Oceania (New Zealand). The WHO Composite International Diagnostic Interview (CIDI) was used to assess the prevalence and correlates of a wide variety of mental and substance disorders. This paper focuses on lifetime use and age of initiation of tobacco, alcohol, cannabis, and cocaine. Alcohol had been used by most in the Americas, Europe, Japan, and New Zealand, with smaller proportions in the Middle East, Africa, and China. Cannabis use in the US and New Zealand (both 42%) was far higher than in any other country. The US was also an outlier in cocaine use (16%). Males were more likely than females to have used drugs; and a sex-cohort interaction was observed, whereby not only were younger cohorts more likely to use all drugs, but the male-female gap was closing in more recent cohorts. The period of risk for drug initiation also appears to be lengthening longer into adulthood among more recent cohorts. Associations with sociodemographic variables were consistent across countries, as were the curves of incidence of lifetime use.

CONCLUSIONS

Globally, drug use is not distributed evenly and is not simply related to drug policy, since countries with stringent user-level illegal drug policies did not have lower levels of use than countries with liberal ones. Sex differences were consistently documented, but are decreasing in more recent cohorts, who also have higher levels of illegal drug use and extensions in the period of risk for initiation.

Cost of disorders of the brain in Italy

The aim of this study was to estimate the cost of "brain" disorders in Italy. Country-specific prevalence and health-economic data on addiction, affective, anxiety and psychotic disorders, tumours, dementia, epilepsy, migraine/other headaches, multiple sclerosis, Parkinson's disease, stroke and head trauma were reviewed. Direct medical/non-medical and indirect costs were computed. Population-based samples and national or regional registries were used. The Italian population expected with a brain disorder was 12.4 million in 2004. The highest cost per case was for tumours and multiple sclerosis; the lowest was for anxiety disorders and migraine. Dementia (8.6 billion euros), psychotic and affective disorders (18.7 billion euros), migraine (3.5 billion euros) and stroke (3.4 billion euros) represented the highest total costs. Direct medical costs were predominant for psychiatric and neurosurgical disorders, direct non-medical costs for dementia, and indirect costs for neurological disorders. The total cost of brain disorders in Italy was 40.8 billion euros, 3% of the gross national product, and 706 euros per Italian citizen/year. This figure is however likely to be underestimated as it is based on retrospective methodology and samples of brain disorders, and does not include intangible costs.

Adverse parenting as a risk factor in the occurrence of anxiety disorders : a study in six European countries

OBJECTIVE

The aim of the study was to test the homogeneity of the association between adverse parenting and anxiety disorders within these disorders as well as among six European countries.

METHOD

Based on data from 8,232 respondents (part II sample) originating from the European study of the epidemiology of mental disorders (ESEMeD), we examined the association between three dimensions of parental rearing (care, overprotection, authoritarianism) measured by a short form of the parental bonding instrument (PBI) and anxiety disorders by computing one logistic regression model per disorder.

RESULTS

A similar pattern of recalled parenting behaviour across the four anxiety disorders assessed was found, with care and overprotection having the strongest associations. There were only minor country-specific variations of this pattern.

CONCLUSION

Our results suggest an association between adverse parenting and the risk of anxiety disorders in particular as well as psychiatric disorders in general that is rather non-disorder specific.

Psychometric properties of the World Health Organization Disability Assessment Schedule used in the European Study of the Epidemiology of Mental Disorders

This study assessed the factor structure, internal consistency, and discriminatory validity of the World Health Organization Disability Assessment Schedule (WHODAS) version used in the European Study of the Epidemiology of Mental Disorders (ESEMeD). In total 8796 adults were assessed using the ESEMeD WHODAS (22 severity and 8 frequency items). An Exploratory Factor Analysis (EFA) with promax rotation was done with a random 50%. The other half was used for confirmatory factor analysis (CFA) comparing models (a) suggested by EFA; (b) hypothesized a priori; and (c) reduced with four items. A CFA model with covariates was conducted in the whole sample to assess invariance across Mediterranean (Spain, France and Italy) and non-Mediterranean (Belgium, Germany and the Netherlands) countries. Cronbach's alphas and discriminatory validity were also examined. EFA identified seven factors (explained variance: 80%). The reduced model (six factors, four frequency items excluded) presented the best fit [Confirmatory Fit Index (CFI) = 0.992, Tucker-Lewis Index (TLI) = 0.996, Root Mean Square Error of Approximation (RMSEA) = 0.024]. The second-order factor structure also fitted well (CFI = 0.987, TLI = 0.991, RMSEA = 0.036). Measurement non-invariance was found for Embarrassment. Cronbach's alphas ranged from 0.84 for Participation to 0.93 for Mobility. Preliminary data suggest acceptable discriminatory validity. Thus, the ESEMeD WHODAS may well be a valuable shortened version of the WHODAS-II, but future users should reconsider the filter questions.

Prevalence of suicide ideation, plans, and attempts and related risk factors in Italy: results from the European Study on the Epidemiology of Mental Disorders--World Mental Health study

BACKGROUND

As in other Mediterranean countries, suicide mortality rates in Italy are generally lower than they are in Northern and Central European countries and on other continents (eg, North America, Australia). Yet, no studies to date have examined the prevalence of and risk factors for suicide ideation, plans, and attempts, in the general population in Italy.

METHODS

Suicide ideation, plans, and attempts and potential risk factors were assessed in a community survey conducted with 4712 adult respondents (response rate, 71.2%). The participants had been selected from Italian municipality resident registries and made up a stratified, multistage, clustered probability sample. The project was part of the World Health Organization World Mental Health (WMH) Survey Initiative.

RESULTS

The lifetime prevalence (SE) of suicide ideation, plans, and attempts was 3.0% (0.3), 0.7% (0.1), and 0.5% (0.1), respectively. Prevalence rates of these suicide-related phenomena did not differ by Italian geographic macro-area (Northern, Central, and Southern Italy, including the islands of Sicily and Sardinia). Among ideators, the probability of ever making a plan was 24.6% (4.0) and attempt was 18.2% (4.5). The probability of making an attempt for ideators having made a suicide plan was nearly 50%. Risk factors for lifetime suicide-related phenomena were female sex, younger cohort, fewer years of education, and earlier onset age of suicide ideation. The presence of a common mental disorder, especially if comorbid, was associated with a significantly increased risk for all suicide phenomena investigated (ideation, plans, and attempts suicide). There were no substantial differences in the frequency of these phenomena among the 3 main macro-areas examined, that is, Northern, Central, and Southern Italy (including Sicily and Sardinia), which conversely show marked climate, socioeconomic, and cultural differences.

CONCLUSION

As shown in previous studies examining suicide, suicide continuum phenomena (in terms of ideation, plans, and attempt) in Italy were lower than typically observed for other European countries and did not differ for different macro-areas presenting remarkably different socioeconomic conditions. Prevalence rates of common mental disorders were equally lower in Italy than in other European countries. Although the detection of mental disorders represents an important step in suicide prevention, the correlations observed between various suicidal continuum manifestations suggest that timely recognition of suicide ideation and plans is an equally crucial factor in the implementation of effective preventive policies.

Delays in seeking treatment for mental disorders in the Belgian general population

OBJECTIVES

To provide data on rates and predictors of lifetime treatment for mental disorders in Belgium from the European Study on the Epidemiology of Mental Disorders (ESEMeD).

MATERIAL AND METHOD

This is a cross-sectional population study of 1,043 non-institutionalized adult (18+) inhabitants from Belgium, The third version of the Composite International Diagnostic Interview (CIDI-3.0) was administered to assess lifetime mental disorders according to the Diagnostic and Statistical Manual, 4th version (DSM-IV), failure and delay of treatment for mental disorders, the duration of the delay between onset of the disorder and first treatment contact, and the proportion of persons seeking help in the same year as the onset of the disorder.

RESULTS

Cumulative lifetime probability curves show that the vast majority of persons with mental disorders will eventually make a first treatment contact, although more so for mood (93.7%) and anxiety disorders (84.5%) than for alcohol disorders (61.2%). Median duration of delay in treatment was lowest for mood disorders (1 year), but peaked for anxiety (16 years) and alcohol disorders (18 years). Both older cohorts and late age of onset of the disorder predicted a higher probability of lifetime treatment.

CONCLUSION

Although most disorders are eventually treated, the delays between onset of the disorder and first treatment contact are impressive, despite the high-density and high accessibility of primary and specialized care in Belgium.

Lifetime risk and age-of-onset of mental disorders in the Belgian general population

AIMS

To estimate lifetime risk and age of onset of mental disorders in the adult general population of Belgium.

METHOD AND MATERIALS

For the World Mental Health Surveys of the World Health Organization, a representative random sample of non-institutionalized inhabitants from Belgium aged 18 or older (n = 2419) were interviewed between April 2001 and June 2002. The interview took place by means of the Composite International Diagnostic Interview, version 3.0. Lifetime prevalence, projected lifetime risk, and age-of-onset of mental disorders were assessed.

RESULTS

Lifetime risk for any mental disorder was 37.1%: 22.8% for mood disorders, 15.7% for anxiety disorders, and 10.8% for alcohol disorders. Median age of onset was 38 years for mood, 14 years for anxiety, and 23 years for alcohol disorders. Prevalence estimates of mood and alcohol disorders were significantly higher in the cohorts between 18 and 34 years.

CONCLUSION

This is the first study that assessed projected lifetime risk and age of onset of mental disorders in the Belgian general population. About one-third of the Belgian non-institutionalized adult population will meet the criteria for a DSM-IV mental disorder at some time during their life. Median age of onset varies from disorder to disorder and younger cohorts had higher likelihood for developing mental disorders.

Mental disorders among adults with asthma: results from the World Mental Health Survey

OBJECTIVE

Our objectives were (a) to determine which common mental disorders are associated with asthma in the general population after controlling for age and sex, and (b) to assess whether the associations of mental disorders with asthma are consistent across diverse countries.

METHOD

Eighteen population surveys of household-residing adults were carried out in 17 countries (N=85,088). Mental disorders were assessed with the Composite International Diagnostic Interview 3.0, a fully structured diagnostic interview. The disorders considered here are 12-month anxiety disorders (generalized anxiety disorder, panic disorder/agoraphobia, posttraumatic stress disorder and social phobia), depressive disorders (dysthymia and major depressive disorder) and alcohol use disorders (abuse and dependence). Asthma was ascertained by self-reports of lifetime diagnosis among a subsample (n=42,697).

RESULTS

Pooled estimates of age-adjusted and sex-adjusted odds of mental disorders among persons with asthma relative to those without asthma were 1.6 [95% confidence interval (95% CI)=1.4, 1.8] for depressive disorders, 1.5 (95% CI=1.4, 1.7) for anxiety disorders and 1.7 (95% CI=1.4, 2.1) for alcohol use disorders.

CONCLUSION

This first cross-national study of the relationship between asthma and mental disorders confirms that a range of common mental disorders occurs with greater frequency among persons with asthma. These results attest to the importance of clinicians in diverse settings being alert to the co-occurrence of these conditions.

Parental bonding and suicidality in adulthood

OBJECTIVE

The short-term effect of an adverse parental child rearing style on suicidality in adolescence has been extensively discussed. Nevertheless, little is known about the long-term effect of adverse parental child rearing on lifetime suicidality in adulthood. So the present study aims to examine the relation between parental bonding on the one hand and suicidality in adulthood on the other.

METHOD

We used data from 7740 respondents of the European Study of Epidemiology of Mental Disorders project, a cross-sectional household survey carried out in six European countries. The data were assessed with the World Mental Health Composite International Diagnostic Interview, a comprehensive, fully structured psychiatric diagnostic interview. Suicidality was categorized as follows: 'no ideation', 'ideation', 'attempt'. Parental bonding was assessed by means of a three-factor ('care', 'overprotection', 'authoritarianism') short form of the Parental Bonding Instrument. Using a multinomial-logistic regression model to investigate the association between these two constructs, we also adjusted for mood disorders, anxiety disorders, alcohol abuse/dependence and possible country effects.

RESULTS

We found associations between low maternal and paternal care on the one hand and suicidality on the other. Country-specific differences proved negligible.

CONCLUSIONS

Prevention programs can help better equip parents in their child-rearing role to create a more caring parenting environment. This can be a protective factor for suicidality in adulthood. Nevertheless, more efforts are necessary to better describe the paths that lead from child-rearing behaviour to suicidality in adulthood.

Prevalence of common mental disorders in Italy: results from the European Study of the Epidemiology of Mental Disorders (ESEMeD)

OBJECTIVE

To present 1-month, 12-month and lifetime prevalence estimates of mood, anxiety and alcohol disorders in Italy; and the socio-demographic correlates and comorbidity patterns of these estimated disorders.

METHOD

A representative random sample of non-institutionalised citizens of Italy aged 18 or older (N=4,712) was interviewed between January 2001 and July 2003, with a weighted response rate of 71.3%. DSM-IV disorders were assessed by lay interviewers using Version 3.0 of the Composite International Diagnostic Interview (CIDI).

RESULTS

A total of 11% of respondents reported a lifetime history of any mood disorder, 10.3% any anxiety disorder and 1.3% any alcohol disorder. About 5% reported having an anxiety disorder in the past 12 months compared to 3.3% for any mood disorder and 0.2% for any alcohol disorder. Major depression and specific phobia were the most common mental disorders. Women were twice as likely as men to report a mood disorder and four times as likely as men to report an anxiety disorder, while men were twice as likely as women to report an alcohol disorder. High comorbidity of mood and anxiety disorders was observed. Prevalence estimates were generally lower than in parallel surveys carried out in other Western European countries.

CONCLUSION

A high proportion of adults in Italy have a history of mood, anxiety or alcohol disorders. The lower than expected prevalence estimate of alcohol use disorder may be due to under-reporting or to low social harm from alcohol consumption.

Lifetime prevalence and projected lifetime risk of DSM-IV disorders in Te Rau Hinengaro: the New Zealand Mental Health Survey

OBJECTIVE

To estimate the lifetime prevalence and projected lifetime risk at age 75 years of DSM-IV disorders in New Zealand.

METHOD

A nationwide face-to-face household survey carried out in 2003-2004. A fully structured diagnostic interview, the World Health Organization Composite International Diagnostic Interview (CIDI 3.0), was used. There were 12,992 completed interviews from participants aged 16 years and over. The overall response rate was 73.3%. In this paper, the outcomes reported are lifetime prevalence and projected lifetime risk at age 75 years.

RESULTS

The lifetime prevalence of any disorder was 39.5%. The lifetime prevalences for disorder groups were: anxiety disorders, 24.9%; mood disorders, 20.2%; substance use disorders, 12.3%; and eating disorders, 1.7%. The prevalences for all disorders were higher in the younger age groups. Females had higher prevalences of anxiety, mood and eating disorders compared with males; males had higher prevalences of substance use disorders. The estimated projected lifetime risk of any disorder at age 75 years was 46.6% with the median age of onset being 18 years. Adjustment for age, sex, education and household income did not remove all differences between Māori and the composite other ethnic group in the risk of disorder (hazard ratio = 1.1-1.4). After adjustment, hazard ratios for Pacific people ranged from 0.8 to 2.5.

CONCLUSIONS

These results confirm those of other studies: mental disorders are relatively common and tend to have early onset. Females are more likely to experience anxiety, mood and eating disorders than males, who experience more substance use disorders. Adjustment for socioeconomic factors and demography does not explain all ethnic differences, although remaining differences are small relative to cohort and even sex differences.

Who visits the psychiatric emergency room for the first time?

OBJECTIVE

To examine patient and system characteristics of first-time ("incident") vs. recurrent ("recurrent") use of a psychiatric emergency room (PER).

METHODS

Data on demographic and clinical characteristics and health service utilization were collected for incident and recurrent users (n=3,719) who visited the PER of the university hospital in Leuven, Belgium, between March 2000 and March 2002.

RESULTS

About 64% (n=2,368) were incident and 36% (n=1,351) were recurrent users. The PER was the first treatment setting ever for 50% of the incident users. Incident users were most likely over 69 years (OR=2.84, P<0.001), employed (OR=2.21, P<0.001), or referred by a health care professional (OR=1.72, P<0.001). They were less likely to have a personality disorder (OR=0.40, P<0.001) or to have used inpatient or outpatient services in the past (OR's 0.11 and 0.65, respectively, P<0.001). About 44% were admitted, 38% referred for outpatient treatment, 9% referred to the outpatient crisis-intervention program, and 9% refused any follow-up.

CONCLUSIONS

The PER was a first treatment setting ever for 1 in 3 patients. Incident and recurrent users differed in sociodemographic characteristics, pathways to care, service use, and the presence of a personality disorder. They did not differ in axis 1 disorders, comorbid mental disorders, or pathways after care.

Relationship between parental bonding and mood disorder in six European countries

The linkage between adverse parental child-rearing styles and the occurrence of mood disorders in adulthood has been investigated in a number of studies from different countries and cultural backgrounds. However, as direct cross-cultural comparisons hardly exist, little is known about cultural variations of this relationship. The European Study of the Epidemiology of Mental Disorders (ESEMeD) is a cross-sectional study in a stratified multi-stage random sample of 21,425 adults (18 years or older) from the general population of six European countries (Belgium, France, Germany, Italy, Netherlands, and Spain). Parental child-rearing styles were measured by means of a short form of the Parental Bonding Instrument (PBI) in 8,232 of the respondents. Based on the extraction and confirmation of a three-factor model of the PBI in a previous study, the association between parental bonding and mood disorders was studied by computing hierarchical nested multiple logistic regression models. The relationship between parental child-rearing styles and mood disorders was mostly homogeneous across the six countries. The PBI dimensions maternal and paternal care had the strongest associations with mood disorders. A significant association of overprotection was observable only for the mother. There was no significant relationship between authoritarianism and the occurrence of mood disorders. In the European countries studied, the association between parental child-rearing styles and the occurrence of mood disorders appears not to be culture-dependent. It would be of interest to assess whether this also holds for the rest of Europe and non-European countries.

Comorbid painful physical symptoms and depression: prevalence, work loss, and help seeking

BACKGROUND

Painful physical symptoms (PPS) are frequent in patients with Major Depressive Episode (MDE). Here, the 12-month prevalence and sociodemographic characteristics of PPS were examined taking into account somatic comorbidity; quantitative and qualitative aspects of MDE with or without PPS were investigated as well as their impact on work loss days (WLD). Finally, help seeking and delay in help seeking were explored.

METHODS

In a cross-sectional, population-based study, a representative random sample of non-institutionalised adults from Belgium, France, Germany, Italy, the Netherlands and Spain (N = 21,425) was interviewed using the World Mental Health Composite Diagnostic Interview (CIDI 3.0 of the WHO).

RESULTS

PPS were reported by 29% of respondents without MDE and by 50% in those with MDE. Female gender, higher age and lower educational level were predictive of PPS. PPS were more frequent in more severely depressed patients but no qualitative differences were found in MDE with and MDE without PPS. An additive effect of MDE and PPS was found on the WLD score. Whether a comorbid somatic disorder was present or not did not change the findings. Finally, respondents with MDE and PPS had lower rates of help seeking for emotional reasons and show a trend to delay their help seeking longer.

LIMITATIONS

The most important limitation of this study was its reliance on self-report data about somatic disorders.

CONCLUSION

Approximately one in two persons with a mood disorder also reported the presence of PPS. MDE and PPS result in decreased productivity and in lower rates of help seeking.

Functional disability of mental disorders and comparison with physical disorders: a study among the general population of six European countries

OBJECTIVE

To examine the association of mental and physical disorders with multiple domains of functioning and compare the two.

METHOD

Data were derived from the European Study of the Epidemiology of Mental Disorders, a general population study in which adults (n > 21,000) from Belgium, France, Germany, Italy, the Netherlands and Spain were assessed using the Composite International Diagnostic Interview (mental disorders), World Health Organization Disability Assessment Schedule second edition (functional disability) and self-report (physical disorders). Means in different groups were compared using the Mann-Whitney U-test and multiple regression analyses.

RESULTS

Mental disorders were related to disability in all domains of functioning: anxiety disorders the most, followed by mood disorders, and finally alcohol disorders. The findings suggest that mental disorders are associated with similar or higher levels of disability in all domains, except getting around, than arthritis and heart disease.

CONCLUSION

Mental disorders are associated with a similar or higher negative impact on daily functioning than arthritis and heart disease.

The state of mental health in old-age across the 'old' European Union-- a systematic review

OBJECTIVE

The paper provides the first syllabus on the prevalence of mental disorders in old-age focusing on surveys conducted in the 15 countries, which comprised the 'old' European Union.

METHOD

A systematic search of the literature published from 1990 onwards was conducted.

RESULTS

Mental disorders in old-age are common. The most serious threats to mental health in old-age are posed by dementia and depression. It is a clear cut finding that dementia exponentially increases with age. The basic issue of whether depression increases or decreases with age remains unsolved. Databases on substance use, mild cognitive impairment, psychotic syndromes, anxiety, and somatoform disorders in old-age are much smaller, making conclusions difficult to draw.

CONCLUSION

Numerous questions in the field remain to be answered. Concerted action is needed to produce comparable data across Europe.

Prevalencia de los trastornos mentales y factores asociados: resultados del estudio ESEMeD-España

BACKGROUND AND OBJECTIVE

The ESEMeD-Spain project is an epidemiological study about mental disorders in Spain. We present 12 month-prevalence and lifetime-prevalence of the main mood, anxiety and alcohol use disorders; the influence of sociodemographic factors on its presence and age of onset of the disorders.

SUBJECTS AND METHOD

Cross-sectional household survey of a representative sample of the population of Spain 18 years or older. Sample size was 5.473 individuals. The WHO World Mental Health Survey Initiative version of the Composite International Diagnostic Interview (WMH-CIDI) was used. Response rate was 78.6%. Results have been weighted to represent the population of Spain.

RESULTS

19.5% of the individuals presented a mental disorder sometime in their lifetime (lifetime-prevalence) and 8.4% in the last 12 months (12 month-prevalence). The most frequent mental disorder was major depressive episode, with a 12-month prevalence of 3.9% and a lifetime-prevalence of 10.5%. The other most lifetime prevalent disorders were specific phobia, alcohol abuse disorder, and dysthymia. Factors associated to presenting a mental disorder were being female, being separated, divorced or widowed, and being unemployed, on sick leave or incapacitated. Social phobia, agoraphobia and specific phobia appear at younger ages, while mood disorders and panic disorder appears later in life.

CONCLUSIONS

The ESEMeD-Spain study can provide careful outcomes to understand the impact of mental disorders in Spain.

Predicting aftercare in psychiatric emergencies

BACKGROUND

Aftercare dispositions in psychiatric emergencies have often been limited to the classic armamentarium of admission vs nonadmission. It is unknown to what extent there are differences in predicting follow-up after psychiatric emergency room (PER) visits when focusing on a broader scope of aftercare possibilities.

MATERIAL AND METHODS

This observational study describes and predicts aftercare dispositions after a psychiatric emergency referral: admission, onsite short-term crisis-intervention program (CIP), refusal of any aftercare, and outpatient aftercare. From March 2000 until March 2002, PER patients (N=3,719) of the university hospital were monitored regarding sociodemographic and clinical characteristics, and use of health services.

RESULTS

Forty-four percent were admitted, 38% were referred to outpatient treatment, 9% refused any aftercare, and the remainder was referred to the CIP. Psychotic patients were most likely to be admitted [odds ratios (ORs) between 5.98 and 6.52], followed by patients with suicidal symptoms (OR=2.25) and those who reported outpatient service utilization (OR=1.43). Young patients (OR=3.36) or those with anxiety disorders (OR=2.03) were most likely to be referred for outpatient aftercare. Patients diagnosed with a personality disorder were at highest risk of refusing any aftercare (OR=1.81).

CONCLUSION

Despite the existence of a short-term onsite CIP, the majority of the patients were admitted after PER referral. We assume that the existence of this program decreased the number of patients who otherwise would refuse all aftercare. More research is needed in order to explain aftercare dispositions more appropriately.
