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.

Modified WHODAS-II provides valid measure of global disability but filter items increased skewness

OBJECTIVE

The WHODAS-II was substantially modified for use in the World Mental Health Surveys. This article considers psychometric properties and implications of filter items used to reduce respondent burden of the modified WHODAS-II.

STUDY DESIGN AND SETTING

Seventeen surveys in 16 countries administered a modified WHODAS-II to population samples (N=38,934 adults). Modifications included introducing filter questions for four subscales and substituting questions on the number of days activity was limited for the Life Activities domain. We evaluated distributional properties, reliability, and validity of the modified WHODAS-II.

RESULTS

Most respondents (77%-99%) had zero scores on filtered subscales. Lower bound estimates of internal consistency (alpha) for the filtered subscales were typically in the 0.70s, but were higher for the Global scale. Loadings of subscale scores on a Global Disability factor were moderate to high. Correlations with the Sheehan Disability Scale were modest but consistently positive, while correlations with SF-12 Physical Component Summary were considerably higher. Cross-national variability in disability scores was observed, but was not readily explainable.

CONCLUSIONS

Internal consistency and validity of the modified WHODAS-II was generally supported, but use of filter questions impaired measurement properties. Group differences in modified WHODAS-II disability scores may be compared within, but not necessarily across, countries.

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.

The impact of home hospitalization on healthcare costs of exacerbations in COPD patients

Home-hospitalization (HH) improves clinical outcomes in selected patients with chronic obstructive pulmonary disease (COPD) admitted at the emergency room due to an exacerbation, but its effects on healthcare costs are poorly known. The current analysis examines the impact of HH on direct healthcare costs, compared to conventional hospitalizations (CH). A randomized controlled trial was performed in two tertiary hospitals in Barcelona (Spain). A total of 180 exacerbated COPD patients (HH 103 and CH 77) admitted at the emergency room were studied. In the HH group, a specialized respiratory nurse delivered integrated care at home. The average direct cost per patient was significantly lower for HH than for CH, with a difference of euro 810 (95% CI, euro 418-1,169) in the mean cost per patient. The magnitude of monetary savings attributed to HH increased with the severity of the patients considered eligible for the intervention.

[The impact of mood and anxiety disorders, and physical chronic conditions in the quality of life of general population of Spain. Results of the ESEMeD-Spain study]

INTRODUCTION

Mental disorders and chronic physical conditions significantly impair health related quality of life (HRQOL). To date, there are no studies in the general population of Spain about their impact. The aim of the present study is to evaluate the impact of mood and anxiety disorders and chronic physical conditions in HRQOL and functional disability (estimated considering work loss days).

METHODS

The ESEMeD-Spain is an epidemiological study carried out in the general population of Spain aged 18 years or older. Mental disorders were assessed with the Composite International Diagnostic Interview (CIDI 3.0); the HRQOL with the SF-12; and functional disability with the WHO Disability Assessment Schedule. Additionally, chronic physical conditions were assessed.

RESULTS

A total of 5,473 individuals were assessed. Response rate was 78.6 %. Mental disorders, specially mood disorders, showed the highest impairment in HRQOL and functional disability (more work loss days). This impairment was even higher than the impairment associated to chronic physical conditions. Comorbidity between mood and anxiety disorders was associated to the worst HRQOL. In general, mental HRQOL was more impaired than physical HRQOL.

CONCLUSIONS

Mood disorders substantially impair HRQOL and augment functional disability in Spain. Their comorbidity with anxiety disorders in especially impairing.

[Mental health care use in the Spanish general populations. Results of the ESEMeD-Spain study]

INTRODUCTION

Between 17% and 30% of the world population suffers from a mental disorder in a given year and only a small proportion of them established contact with health services. This information is not available concerning the Spanish population. This study aims to describe the health services utilization related with mental disorders in Spain, as well as to identify factors related with such utilization.

METHODS

The ESEMeD-Spain is an epidemiological study carried out on a representative sample of the Spanish adult general population, with a sample size of 5,473 individuals. We used the Composite International Diagnostic Interview (version 3.0) to collect information concerning mental disorders symptoms, health services utilization related with mental health, and administered treatments, with a 12 months time frame.

RESULTS

57% of those suffering from a mood disorder, 30.3 % of those suffering from an anxiety disorder and 71.7% of those suffering from both contacted health services in the year they suffered the disorder. Psychiatrists were the most frequently consulted professionals when a 12 month mental disorder was present, with the exception of anxiety disorders or comorbid mood-anxiety disorders. A 30.8% of those with any 12 month mental disorder who did consult were not prescribed with any treatment. Variables significantly related to 12 month health services utilization were age, gender, marital status, and mental disorders.

CONCLUSIONS

A large proportion of individuals suffering from mental disorders do not use health services or, if indeed use them, do not receive any type of treatment.

[Psychotropic medications use in Spain. Results of the ESEMeD-Spain study]

INTRODUCTION

Psychotropic drugs are frequently used in the population and account for a big share of the Spanish health budget. This study aims to describe the patterns of use of psychotropic drugs in the Spanish general population and its relationship with mental health.

METHODS

A stratified, multistage, clustered area, probability sample design was used and 5,473 non-institutionalized individuals older than 18 were randomly selected among the Spanish population. They were administered the Spanish version of the World Health Organization- Composite International Diagnostic Interview (CIDI 3.0). Information on previous 12-months psychiatric symptoms and psychotropic drugs use was obtained. The proportion of individuals using psychotropic drugs was estimated and stratified according mental health diagnosis. Multivariate analyses were carried out in order to assess the influence of sociodemographic factors on use.

RESULTS

16% of the sample had used some psychotropic drug. Benzodiacepines (11.4 %) and antidepressants (4.7%) were the most commonly used and the most common combination (1.8%). Women showed the highest use of any drug (odds ratio [OR]: 2.1; 95 confidence interval [CI]: 1.7-2.5), benzodiacepines (OR: 2.3; 95 CI: 1.9-2.8), antidepressants (OR: 2.2; 95 CI: 1.6-3.1) and antipsychotics (OR: 1.9; 95 CI: 1.2-3.0). The odds of use did increase with age, and was related with the presence and number of mental disorders.

CONCLUSIONS

Use of psychotropic drugs in the Spanish general population is high, although many individuals with mental disorders remain untreated. Gender and age showed an association with psychotropic drug use independent of mental health.

[One year prevalence of mental disorders comorbidity and associated socio-demographic risk factors in the general population of Spain. Results of the ESEMeD-Spain study]

INTRODUCTION

Comorbidity among mental disorders in the general population is common, affecting more than the 50 % of individuals with a lifetime mental disorder. In Spain, there are no data describing it or its associated risk factors.

METHOD

The ESEMeD-Spain study is an epidemiological study assessing mental disorders in a sample of 5,473 individuals from the general population of Spain aged 18 years or older. The aims of the present study were to evaluate the frequency of mental disorders comorbidity in Spain (assessed with the Composite International Diagnostic Interview: CIDI 3.0) and associated sociodemographic risk factors. Response rate was 78.6%.

RESULTS

Mood disorders showed the highest comorbidity frequency. Analysing specific disorders, generalized anxiety disorder, dysthymic and panic disorders showed the highest comorbidity percentages. Female gender, ages above 24 years old and being previously married were found to be risk factors associated to the presence of comorbid mood and anxiety disorders.

CONCLUSIONS

As it has been suggested for other European countries and for the United States, in the general population of Spain mental disorders, specially mood disorders, are frequently comorbid. When treating mental disorders, comorbidity should be taken into account.

Risk factors for suicidality in Europe: results from the ESEMED study

BACKGROUND

Precise knowledge of the epidemiology of suicidality provides necessary information for designing prevention programs. The aims of the present study were to investigate the prevalence and correlates of suicidal ideas and attempts in the general population of Europe.

METHODS

The European Study on the Epidemiology of Mental Disorders (ESEMED) is a cross-sectional household survey carried out in a probability representative sample of non-institutionalised adults (aged 18 years or older) of six European countries (Belgium, France, Germany, Italy, the Netherlands and Spain). The Composite International Diagnostic Interview (CIDI 3.0) was administered to 21,425 individuals.

RESULTS

Lifetime prevalence of suicidal ideation was 7.8% and of suicidal attempts 1.3%. Being women, younger and divorced or widowed were associated with a higher prevalence of suicide ideation and attempts. Psychiatric diagnoses were strongly related to suicidality. Among them, major depressive episode (Rate ratio 2.9 for lifetime ideas and 4.8 for lifetime attempts), dysthymia (RR 2.0 and 1.6), GAD (RR 1.8 and 2.3 for lifetime), PTSD (RR 1.9 and 2.0) and alcohol dependence (RR 1.7 and 2.5) were the most important. Population attributable risks for lifetime suicidal attempt was 28% for major depression.

LIMITATIONS

Information about suicidal ideas and attempts was self reported, psychiatric diagnoses were made using fully structured lay interviews rather than clinician-administered interviews.

CONCLUSIONS

In spite of meaningful country variation in prevalence, risk factors for suicidality are consistent in the European countries. Population prevention programmes should focus on early diagnosis and treatment of major depression and alcohol abuse and in those individuals with recent appearance of suicidal ideas.

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.

Population level of unmet need for mental healthcare in Europe

BACKGROUND

The high prevalence of mental disorders has fuelled controversy about the need for mental health services.

AIMS

To estimate unmet need for mental healthcare at the population level in Europe.

METHOD

As part of the European Study of Epidemiology of Mental Disorders (ESEMeD) project, a cross-sectional survey was conducted of representative samples of the adult general population of Belgium, France, Germany, Italy, The Netherlands and Spain (n=8796). Mental disorders were assessed with the Composite International Diagnostic Interview 3.0. Individuals with a 12-month mental disorder that was disabling or that had led to use of services in the previous 12 months were considered in need of care.

RESULTS

About six per cent of the sample was defined as being in need of mental healthcare. Nearly half (48%) of these participants reported no formal healthcare use. In contrast, only 8% of the people with diabetes had reported no use of services for their physical condition. In total, 3.1% of the adult population had an unmet need for mental healthcare. About 13% of visits to formal health services were made by individuals without any mental morbidity.

CONCLUSIONS

There is a high unmet need for mental care in Europe, which may not be eliminated simply by reallocating existing healthcare resources.

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.

Treatment adequacy of anxiety and depressive disorders: primary versus specialised care in Spain

BACKGROUND

Literature suggests that a high proportion of the population with mental disorders remains either untreated or poorly treated. This study aimed to describe the adequacy of treatment for Anxiety and Depressive disorders in Spain, how this differs between providers (primary versus specialised care) and which factors are associated with appropriate care.

METHOD

Data were derived from the Spanish sample (N=5473) of the European Study of the Epidemiology of Mental Disorders (ESEMeD), a cross sectional study in a representative sample of adults. The subsample analyzed was composed by the 133 subjects with a mental disorder in the year prior to the interview who received treatment. Treatment adequacy was evaluated in two different ways: (1) considering definitions of minimally adequate treatment evidence based guidelines and criteria used in other epidemiological studies; (2) considering experts rating of treatment appropriateness based on the information contained in the case vignettes created from the CIDI answers. Generalised Estimating Equation (GEE) models and simple logistic regression were conducted to assess the correlates of adequate treatment.

RESULTS

Similar proportions of patients in specialty and general medical treatment received a minimally adequate treatment (31.8% and 30.5%, respectively). Associated factors to appropriateness were living in a large city, having a high educational level, and having a good self rated health state.

LIMITATIONS

Treatment adequacy was based on simple information and criteria.

CONCLUSIONS

Only one third of the mental health treatment in Spain met minimal adequacy criteria. More research is needed in order to find out reasons for these low rates.

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.

Concordance of the Composite International Diagnostic Interview Version 3.0 (CIDI 3.0) with standardized clinical assessments in the WHO World Mental Health surveys

The DSM-IV diagnoses generated by the fully structured lay-administered Composite International Diagnostic Interview Version 3.0 (CIDI 3.0) in the WHO World Mental Health (WMH) surveys were compared to diagnoses based on follow-up interviews with the clinician-administered non-patient edition of the Structured Clinical Interview for DSM-IV (SCID) in probability subsamples of the WMH surveys in France, Italy, Spain, and the US. CIDI cases were oversampled. The clinical reappraisal samples were weighted to adjust for this oversampling. Separate samples were assessed for lifetime and 12-month prevalence. Moderate to good individual-level CIDI-SCID concordance was found for lifetime prevalence estimates of most disorders. The area under the ROC curve (AUC, a measure of classification accuracy that is not influenced by disorder prevalence) was 0.76 for the dichotomous classification of having any of the lifetime DSM-IV anxiety, mood and substance disorders assessed in the surveys and in the range 0.62-0.93 for individual disorders, with an inter-quartile range (IQR) of 0.71-0.86. Concordance increased when CIDI symptom-level data were added to predict SCID diagnoses in logistic regression equations. AUC for individual disorders in these equations was in the range 0.74-0.99, with an IQR of 0.87-0.96. CIDI lifetime prevalence estimates were generally conservative relative to SCID estimates. CIDI-SCID concordance for 12-month prevalence estimates could be studied powerfully only for two disorder classes, any anxiety disorder (AUC = 0.88) and any mood disorder (AUC = 0.83). As with lifetime prevalence, 12-month concordance improved when CIDI symptom-level data were added to predict SCID diagnoses. CIDI 12-month prevalence estimates were unbiased relative to SCID estimates. The validity of the CIDI is likely to be under-estimated in these comparisons due to the fact that the reliability of the SCID diagnoses, which is presumably less than perfect, sets a ceiling on maximum CIDI-SCID concordance.

Empirical evidence for an invariant three-factor structure of the Parental Bonding Instrument in six European countries

The objective of the present study was to test the Parental Bonding Instrument's (PBI) three-factor structure (care, overprotection, and authoritarianism) found by [Cox, B.J., Enns, M.W., Clara, I.P. 2000, The Parental Bonding Instrument: confirmatory evidence for a three-factor model in a psychiatric clinical sample and in the National Comorbidity Survey, Social Psychiatry and Psychiatric Epidemiology 35 (2000) 353-357.] on an eight-item short form of the scale. A total of 8813 respondents from the six European countries participating in the ESEMeD project (Belgium, France, Germany, Italy, The Netherlands, and Spain) completed either the PBI-paternal or the PBI-maternal scale. Maximum likelihood confirmatory factor analysis was used to compare the original factor model of Cox et al. with a three-factor solution that emerged from an exploration of the structure with principal component factor analysis. When gender and age subgroups, as well as different countries, were taken into account, the accuracy of the model was confirmed. The fit indices for the new model indicated a generally better model fit than the ones for the model originally developed by Cox et al. Further efforts should be directed to the modeling of the dimension authoritarianism. The results provide the opportunity to estimate the influence of the extracted factors on mental disorders in different countries. The application of the short form of the PBI seems suitable primarily for large epidemiological studies.

El Cuestionario de Salud SF-36 español: una década de experiencia y nuevos desarrollos

OBJECTIVE

The Short Form-36 Health Survey (SF-36) is one of the most widely used and evaluated generic health-related quality of life (HRQL) questionnaires. After almost a decade of use in Spain, the present article critically reviews the content and metric properties of the Spanish version, as well as its new developments.

METHODS

A review of indexed articles that used the Spanish version of the SF-36 was performed in Medline (PubMed), the Spanish bibliographic databases IBECS and IME. Articles that provided information on the measurement model, reliability, validity, and responsiveness to change of the instrument were selected.

RESULTS

Seventy-nine articles were found, of which 17 evaluated the metric characteristics of the questionnaire. The reliability of the SF-36 scales was higher than the suggested standard (Cronbach's alpha) of 0.7 in 96% of the evaluations. Grouped evaluations obtained by meta-analysis were higher than 0.7 in all cases. The SF-36 showed good discrimination among severity groups, moderate correlations with clinical indicators, and high correlations with other HRQL instruments. Moreover, questionnaire scores predicted mortality and were able to detect improvement due to therapeutic interventions such as coronary angioplasty, benign prostatic hyperplasia surgery, and non-invasive positive pressure home ventilation. The new developments (norm-based scoring, version 2, the SF-12 and SF-8) improved both the metric properties and interpretation of the questionnaire.

CONCLUSIONS

The Spanish version of the SF-36 and its recently developed versions is a suitable instrument for use in medical research, as well as in clinical practice.

Health-related quality of life during the bereavement period of caregivers of a deceased elderly person

Few studies have addressed the health-related quality of life (HRQL) impact of bereavement. The objective of this study was to evaluate the HRQL of the main caregiver after the death of a close elderly relative. 142 caregivers were invited to participate in a phone interview with the SF-36. General population SF-36 norms, were used to calculate the gender and age standardised physical component summary (PCS) and mental component summary (MCS) scores. A MCS below 43 was used as an indicator of possible depression. Databases of several patient studies were additionally used to facilitate interpretation of results. 130 caregivers (91.5%) participated, the majority being women (80%), middle aged (56 years), and the spouse (22%) or son/daughter (56%) of the deceased person. Caregivers' SF-36 scores were lower than expected for mental health, role emotional and social functioning. Their MCS was below that expected by 0.6 SD units, whereas their PCS was above by 0.2 SD. The proportion of caregivers with possible depression was 33.8%. First-degree family relationship with the deceased (OR = 4.5), and lower age of the deceased (OR = 3.8) were significantly associated (p < 0.02) to a possible depression. The recent death of an elderly person is associated with significant emotional health impact on the caregiver.

Disability and quality of life impact of mental disorders in Europe: results from the European Study of the Epidemiology of Mental Disorders (ESEMeD) project

OBJECTIVE

This manuscript examines the impact of mental health state and specific mental and physical disorders on work role disability and quality of life in six European countries.

METHOD

The ESEMeD study was conducted in: Belgium, France, Germany, Italy, the Netherlands and Spain. Individuals aged 18 years and over who were not institutionalized were eligible for an in-home computer-assisted interview. Common mental disorders, work loss days (WLD) in the past month and quality of life (QoL) were assessed, using the WMH-2000 version of the CIDI, the WHODAS-II, and the mental and physical component scores (MCS, PCS) of the 12-item short form, respectively. The presence of five chronic physical disorders: arthritis, heart disease, lung disease, diabetes and neurological disease was also assessed. Multivariate regression techniques were used to identify the independent association of mental and physical disorders while controlling for gender, age and country.

RESULTS

In each country, WLD and loss of QoL increased with the number of disorders. Most mental disorders had approximately 1.0 SD-unit lower mean MCS and lost three to four times more work days, compared with people without any 12-month mental disorder. The 10 disorders with the highest independent impact on WLD were: neurological disease, panic disorder, PTSD, major depressive episode, dysthymia, specific phobia, social phobia, arthritis, agoraphobia and heart disease. The impact of mental vs. physical disorders on QoL was specific, with mental disorders impacting more on MCS and physical disorders more on PCS. Compared to physical disorders, mental disorders had generally stronger 'cross-domain' effects.

CONCLUSION

The results suggest that mental disorders are important determinants of work role disability and quality of life, often outnumbering the impact of common chronic physical disorders.

Use of mental health services in Europe: results from the European Study of the Epidemiology of Mental Disorders (ESEMeD) project

OBJECTIVE

Comprehensive information about access and patterns of use of mental health services in Europe is lacking. We present the first results of the use of health services for mental disorders in six European countries as part of the ESEMeD project.

METHOD

The study was conducted in: Belgium, France, Germany, Italy, the Netherlands and Spain. Individuals aged 18 years and over who were not institutionalized were eligible for an computer-assisted interview done at home. The 21 425 participants were asked to report how frequently they consulted formal health services due to their emotions or mental health, the type of professional they consulted and the treatment they received as a result of their consultation in the previous year.

RESULTS

An average of 6.4% of the total sample had consulted formal health services in the previous 12 months. Of the participants with a 12-month mental disorder, 25.7% had consulted a formal health service during that period. This proportion was higher for individuals with a mood disorder (36.5%, 95% CI 32.5-40.5) than for those with anxiety disorders (26.1%, 95% CI 23.1-29.1). Among individuals with a 12-month mental disorder who had contacted the health services 12 months previously, approximately two-thirds had contacted a mental health professional. Among those with a 12-month mental disorder consulting formal health services, 21.2% received no treatment.

CONCLUSION

The ESEMeD results suggest that the use of health services is limited among individuals with mental disorders in the European countries studied. The factors associated with this limited access and their implications deserve further research.

Prevalence, severity, and unmet need for treatment of mental disorders in the World Health Organization World Mental Health Surveys

CONTEXT

Little is known about the extent or severity of untreated mental disorders, especially in less-developed countries.

OBJECTIVE

To estimate prevalence, severity, and treatment of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) mental disorders in 14 countries (6 less developed, 8 developed) in the World Health Organization (WHO) World Mental Health (WMH) Survey Initiative.

DESIGN, SETTING, AND PARTICIPANTS

Face-to-face household surveys of 60 463 community adults conducted from 2001-2003 in 14 countries in the Americas, Europe, the Middle East, Africa, and Asia.

MAIN OUTCOME MEASURES

The DSM-IV disorders, severity, and treatment were assessed with the WMH version of the WHO Composite International Diagnostic Interview (WMH-CIDI), a fully structured, lay-administered psychiatric diagnostic interview.

RESULTS

The prevalence of having any WMH-CIDI/DSM-IV disorder in the prior year varied widely, from 4.3% in Shanghai to 26.4% in the United States, with an interquartile range (IQR) of 9.1%-16.9%. Between 33.1% (Colombia) and 80.9% (Nigeria) of 12-month cases were mild (IQR, 40.2%-53.3%). Serious disorders were associated with substantial role disability. Although disorder severity was correlated with probability of treatment in almost all countries, 35.5% to 50.3% of serious cases in developed countries and 76.3% to 85.4% in less-developed countries received no treatment in the 12 months before the interview. Due to the high prevalence of mild and subthreshold cases, the number of those who received treatment far exceeds the number of untreated serious cases in every country.

CONCLUSIONS

Reallocation of treatment resources could substantially decrease the problem of unmet need for treatment of mental disorders among serious cases. Structural barriers exist to this reallocation. Careful consideration needs to be given to the value of treating some mild cases, especially those at risk for progressing to more serious disorders.

Psychotropic drug utilization in Europe: results from the European Study of the Epidemiology of Mental Disorders (ESEMeD) project

OBJECTIVE

To assess psychotropic drug utilization in the general population of six European countries, and the pattern of use in individuals with different DSM-IV diagnoses of 12-month mental disorders.

METHOD

Data were derived from the European Study of the Epidemiology of Mental Disorders (ESEMeD/MHEDEA 2000), a cross-sectional psychiatric epidemiological study in a representative sample of 21 425 adults aged 18 or older from six European countries (e.g. Belgium, France, Germany, Italy, the Netherlands and Spain). Individuals were asked about any psychotropic drug use in the past 12 months, even if they used the drug(s) just once. A colour booklet containing high-quality pictures of psychotropic drugs commonly used to treat mental disorders was provided to help respondents recall drug use.

RESULTS

Psychotropic drug utilization is generally low in individuals with any 12-month mental disorder (32.6%). The extent of psychotropic drug utilization varied according to the specific DSM-IV diagnosis. Among individuals with a 12-month diagnosis of pure major depression, only 21.2% had received any antidepressants within the same period; the exclusive use of antidepressants was even lower (4.6%), while more individuals took only anxiolytics (18.4%).

CONCLUSION

These data question the appropriateness of current pharmacological treatments, particularly for major depression, in which under-treatment is coupled with the high use of non-specific medications, such as anxiolytics.
