Role of common mental and physical disorders in partial disability around the world

BACKGROUND

Mental and physical disorders are associated with total disability, but their effects on days with partial disability (i.e. the ability to perform some, but not full-role, functioning in daily life) are not well understood.

AIMS

To estimate individual (i.e. the consequences for an individual with a disorder) and societal effects (i.e. the avoidable partial disability in the society due to disorders) of mental and physical disorders on days with partial disability around the world.

METHOD

Respondents from 26 nationally representative samples (n = 61 259, age 18+) were interviewed regarding mental and physical disorders, and day-to-day functioning. The Composite International Diagnostic Interview, version 3.0 (CIDI 3.0) was used to assess mental disorders; partial disability (expressed in full day equivalents) was assessed with the World Health Organization Disability Assessment Schedule in the CIDI 3.0.

RESULTS

Respondents with disorders reported about 1.58 additional disability days per month compared with respondents without disorders. At the individual level, mental disorders (especially post-traumatic stress disorder, depression and bipolar disorder) yielded a higher number of days with disability than physical disorders. At the societal level, the population attributable risk proportion due to physical and mental disorders was 49% and 15% respectively.

CONCLUSIONS

Mental and physical disorders have a considerable impact on partial disability, at both the individual and at the societal level. Physical disorders yielded higher effects on partial disability than mental disorders.

Days out of role due to common physical and mental conditions: results from the WHO World Mental Health surveys

Days out of role because of health problems are a major source of lost human capital. We examined the relative importance of commonly occurring physical and mental disorders in accounting for days out of role in 24 countries that participated in the World Health Organization (WHO) World Mental Health (WMH) surveys. Face-to-face interviews were carried out with 62 971 respondents (72.0% pooled response rate). Presence of ten chronic physical disorders and nine mental disorders was assessed for each respondent along with information about the number of days in the past month each respondent reported being totally unable to work or carry out their other normal daily activities because of problems with either physical or mental health. Multiple regression analysis was used to estimate associations of specific conditions and comorbidities with days out of role, controlling by basic socio-demographics (age, gender, employment status and country). Overall, 12.8% of respondents had some day totally out of role, with a median of 51.1 a year. The strongest individual-level effects (days out of role per year) were associated with neurological disorders (17.4), bipolar disorder (17.3) and post-traumatic stress disorder (15.2). The strongest population-level effect was associated with pain conditions, which accounted for 21.5% of all days out of role (population attributable risk proportion). The 19 conditions accounted for 62.2% of all days out of role. Common health conditions, including mental disorders, make up a large proportion of the number of days out of role across a wide range of countries and should be addressed to substantially increase overall productivity.

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.

Prevalence and correlates of respiratory and non-respiratory panic attacks in the general population

BACKGROUND

Panic attacks are heterogeneous with regards to symptom profile. Subtypes of panic attacks have been proposed, of which the most investigated is respiratory panic attacks (RPA). Limited information exists about RPA in the general population.

METHOD

The prevalence and correlates of RPA and non-respiratory panic attacks (NRPA) were examined in a subsample (n=8.796) of individuals participating in a cross-sectional survey of the adult general population of six European countries. Panic attacks, mental disorders, and chronic physical conditions were assessed with the Composite International Diagnostic Interview (CIDI) 3.0. Data on use of health services and disability were obtained.

RESULTS

The lifetime prevalence of RPA was 6.77 and the 12-month prevalence was 2.26. No robust associations of RPA with sociodemographic characteristics, mental disorders or physical conditions were found as compared to NRPA. RPA were associated with increased use of health services but similar disability in comparison to NRPA.

LIMITATIONS

Few direct data are available on the validity of the CIDI to assess RPA. Other definitions of RPA exist in the literature.

CONCLUSIONS

Our findings suggest that there are very few differences between RPA and NRPA and do not support the need of subtyping panic attacks in current classification systems.

Mental health care and out-of-pocket expenditures in Europe: results from the ESEMeD project

BACKGROUND

Most published data on out-of-pocket spending on mental health originate from the United States, where insurance payments for mental health have traditionally been much less generous than benefits for other health care services. Given the difference in the structure of health care funding in Europe, it is clearly important to obtain similar information on out-of-pocket expenditure in different European countries.

AIM OF THE STUDY

To estimate out-of-pocket costs paid by people who receive mental health care in six European countries (Belgium, France, Germany, Italy, the Netherlands, and Spain).

METHODS

Of the 8,796 participants in a cross-sectional survey conducted in these six European countries, 1,128 reported having consulted a professional for a mental health problem in the year preceding the interview and provided information on how many times in the past year they consulted each type of provider, and the money they and their family members had paid out-of-pocket for their mental health care. In addition to sociodemographic characteristics, information on mental health status was collected using the CIDI 3.0. Descriptive statistics on out-of-pocket expenditure and share of income across countries were generated. Two-part models were employed to identify the relationship between the different covariates, notably the types of providers consulted, and out-of-pocket expenditure.

RESULTS

Overall, 41.0% of those who used services for a mental health problem paid something for the care they received. This represented a minority of respondents in all countries except Belgium (87.9%) and Italy (61.7%). The financial burden of these costs relative to income was found to be low (1.2%), ranging from 0.4% in Germany to 2.3% in France. Out-of-pocket expenditure differed according to the type of providers consulted, with non-physician health professionals and medical specialists being more often associated with significant expenditure.

DISCUSSION AND LIMITATIONS

Although the study is limited principally by data collection from self-report, it is the first of its kind, to our knowledge, and suggests that out-of-pocket costs for mental health care in Europe are relatively low compared to the United States. However, differences between countries exist, which may be partially due to differences in coverage for specialized care.

IMPLICATIONS FOR HEALTH POLICIES

Consultations with non-physician mental health professionals such as psychologists are expensive for patients, since they are reimbursed to a lesser extent than consultations with physicians, or not reimbursed at all. This limits their role and increases the burden on psychiatrists.

IMPLICATIONS FOR FURTHER RESEARCH

Monitoring out-of-pocket spending on mental health, preferably on the basis of administrative data when available, is essential in the current context of cost containment policy, where out-of-pocket spending may be expected to increase.

The ESEMeD-WMH project: strenghtening epidemiological research in Europe through the study of variation in prevalence estimates

The European Study of the Epidemiology of Mental Disorders (ESEMeD) project is the first cross-national European survey to collect data on prevalence, risk factors, health-related quality of life and use of services associated with common mental disorders. Representative samples of the non-institutionalized populations of Belgium, France, Germany, Italy, the Netherlands and Spain were interviewed using the CIDI 3.0, totaling 21,425 adult individuals. There was important variation across countries in prevalence estimates of the disorders studied, with Belgium and France in the highest proportions and Italy and Spain the lowest. Comorbidity of mood and anxiety disorders was frequent in all countries. Use of services due to mental health is low in all European countries, but especially low in Italy. Remarkably, only about one in five participants with a mental disorder had consulted the health services in the prior year. We discuss about the possible explanations of cross-national differences in prevalence estimates of mental disorders, and some of the limitations of the data on alcohol abuse and dependence gathered in the study. We conclude that despite the advances in knowledge about determinants and treatment methods, the care of the mentally ill is rather limited in Europe.

Including information about co-morbidity in estimates of disease burden: results from the World Health Organization World Mental Health Surveys

BACKGROUND

The methodology commonly used to estimate disease burden, featuring ratings of severity of individual conditions, has been criticized for ignoring co-morbidity. A methodology that addresses this problem is proposed and illustrated here with data from the World Health Organization World Mental Health Surveys. Although the analysis is based on self-reports about one's own conditions in a community survey, the logic applies equally well to analysis of hypothetical vignettes describing co-morbid condition profiles.

METHOD

Face-to-face interviews in 13 countries (six developing, nine developed; n=31 067; response rate=69.6%) assessed 10 classes of chronic physical and nine of mental conditions. A visual analog scale (VAS) was used to assess overall perceived health. Multiple regression analysis with interactions for co-morbidity was used to estimate associations of conditions with VAS. Simulation was used to estimate condition-specific effects.

RESULTS

The best-fitting model included condition main effects and interactions of types by numbers of conditions. Neurological conditions, insomnia and major depression were rated most severe. Adjustment for co-morbidity reduced condition-specific estimates with substantial between-condition variation (0.24-0.70 ratios of condition-specific estimates with and without adjustment for co-morbidity). The societal-level burden rankings were quite different from the individual-level rankings, with the highest societal-level rankings associated with conditions having high prevalence rather than high individual-level severity.

CONCLUSIONS

Plausible estimates of disorder-specific effects on VAS can be obtained using methods that adjust for co-morbidity. These adjustments substantially influence condition-specific ratings.

Use of primary and specialized mental health care for a major depressive episode in Spain by ESEMeD respondents

OBJECTIVE

This study described use of services for a major depressive episode and determined factors associated with use in Spain, a country with universal access to care and a relatively low prevalence of depression.

METHODS

Data were from the European Study of the Epidemiology of Mental Disorders (ESEMeD). ESEMeD-Spain was a cross-sectional, general population survey conducted with a representative sample of noninstitutionalized adults (N=5,473). The Composite International Diagnostic Interview was used, and 12-month use of services for a major depressive episode, types of services used, and receipt of minimally adequate treatment were assessed.

RESULTS

Among the 247 respondents with a major depressive episode in the past 12 months, 59% reported any use of past-year services for their disorder; of this group, 76% reported receipt of any active treatment (from a health care or mental health professional). Among respondents with severe depression, 31% used no services. A higher likelihood of service use was found among those who were unemployed or too disabled to work (OR=4.9, CI=1.3-19), who had moderate depression symptoms (OR=3.2, CI=1.1-9.0), and who had one mental disorder comorbid with depression (OR=2.9, CI=1.2-7.0) or two or more such comorbid disorders (OR=4.1, CI=1.9-8.9). In the active treatment group, only 31.2% received treatment that was minimally adequate.

CONCLUSIONS

There is a need in Spain to increase use of services for a major depressive episode, especially among certain population groups, such as women, and to improve adequacy of treatments. The role of specific factors, such as availability of services and of professionals, deserves further research.

Health status of the advanced elderly in six European countries: results from a representative survey using EQ-5D and SF-12

Background

Due to demographic change, the advanced elderly represent the fastest growing population group in Europe. Health problems tend to be frequent and increasing with age within this cohort.

Aims of the study

To describe and compare health status of the elderly population in six European countries and to analyze the impact of socio-demographic variables on health.

Methods

In the European Study of the Epidemiology of Mental Disorders (ESEMeD), representative non-institutionalized population samples completed the EQ-5D and Short Form-12 (SF-12) questionnaires as part of personal computer-based home interviews in 2001-2003. This study is based on a subsample of 1659 respondents aged ≥ 75 years from Belgium (n = 194), France (n = 168), Germany (n = 244), Italy (n = 317), the Netherlands (n = 164) and Spain (n = 572). Descriptive statistics, bivariate- (chi-square tests) and multivariate methods (linear regressions) were used to examine differences in population health.

Results

68.8% of respondents reported problems in one or more EQ-5D dimensions, most frequently pain/discomfort (55.2%), followed by mobility (50.0%), usual activities (36.6%), self-care (18.1%) and anxiety/depression (11.6%). The proportion of respondents reporting any problems increased significantly with age in bivariate analyses (age 75-79: 65.4%; age 80-84: 69.2%; age ≥ 85: 81.1%) and differed between countries, ranging from 58.7% in the Netherlands to 72.3% in Italy. The mean EQ VAS score was 61.9, decreasing with age (age 75-79: 64.1; age 80-84: 59.8; age ≥ 85: 56.7) and ranging from 60.0 in Italy to 72.9 in the Netherlands. SF-12 derived Physical Component Summary (PCS) and Mental Component Summary (MCS) scores varied little by age and country. Age and low educational level were associated with lower EQ VAS and PCS scores. After controlling for socio-demographic variables and reported EQ-5D health states, mean EQ VAS scores were significantly higher in the Netherlands and Belgium, and lower in Germany than the grand mean.

Conclusions

More than two thirds of the advanced elderly report impairment of health status. Impairment increases rapidly with age but differs considerably between countries. In all countries, health status is significantly associated with socio-demographic variables.

Seeking help for mental health problems outside the conventional health care system: results from the European Study of the Epidemiology of Mental Disorders (ESEMeD)

OBJECTIVE

In certain countries, it is not uncommon to turn to professionals outside the conventional health care system for psychological problems. As this situation is not well documented in Europe, we assessed use of nonconventional care for mental health in 6 European countries.

METHOD

A cross-sectional survey was conducted in representative samples of noninstitutionalized adults in 6 European countries. Participants (n = 8796) completed a survey, which included, among other items, the Composite International Diagnostic Interview 3.0 and in-depth questions about lifetime consultations for mental health problems.

RESULTS

Among the respondents (n = 2928) who reported having already sought help in their lifetime for psychological problems (20.0%), 8.6% turned to complementary and alternative medicine (CAM) providers, such as chiropractors and herbalists, and a similar proportion (8.4%) to religious advisers such as ministers, priests, or rabbis. Only a small proportion (2.9%) consulted only these professionals for their problems. CAM providers were more frequently used in the Netherlands (13.5%) and Germany (9.4%), while religious advisers were more often consulted in Italy (12.6%) and Germany (11.6%). Multivariate analyses confirmed differences between countries and revealed that people turning to religious advisers tended to be older, foreign born, and with alcohol problems, whereas those consulting CAM providers were younger, wealthier, and more frequently depressed.

CONCLUSIONS

In Europe, patients who turn to CAM therapists and those who seek help from religious advisers for psychological problems are not exactly the same. In addition, these professionals are not consulted frequently in most countries, and are almost always associated with more traditional follow-up when used.

Obsessive-compulsive symptom dimensions in the general population: results from an epidemiological study in six European countries

BACKGROUND

The prevalence of obsessive-compulsive symptom dimensions and their sociodemographic and psychopathological correlates at the population level are unknown.

METHOD

Obsessive-compulsive symptom dimensions and mental disorders were assessed with the Composite International Diagnostic Interview 3.0 in a random subsample (n=2804) of individuals participating in a cross-sectional survey of the adult general population of six European countries.

RESULTS

The lifetime prevalence of any obsessive-compulsive symptom dimension was 13%. Harm/Checking was the most prevalent dimension (8%) followed by Somatic obsessions (5%) and Symmetry/Ordering (3%). Females were more likely to have symptoms in Contamination/Cleaning (OR=3, 95%CI=1.06-8.51) and Somatic obsessions (OR=1.88, 95%CI=1.05-3.37). All symptom dimensions were associated with an increased risk of most mental (but not physical) disorders. There were some differences in prevalence between countries.

LIMITATIONS

The interference associated with each symptom dimension could not be assessed. Few direct data are available on the validity of the CIDI to assess obsessive-compulsive symptom dimensions.

CONCLUSIONS

Obsessive-compulsive symptom dimensions are relatively frequent in the general population. Their sociodemographic and psychopathological correlates may be slightly different in clinical and community samples. They are associated with an increased risk of most mental disorders.

Impact of recent life events on the health related quality of life of adolescents and youths: the role of gender and life events typologies in a follow-up study

Background

Most studies on the effect of life events (LEs) have been carried out in convenience samples which cannot be considered representative of the general population. In addition, recent studies have observed that gender differences in the health related quality of life (HRQoL) impact of LEs might be lower than believed. We assessed the relationship between LEs and HRQoL in a representative sample of Spanish adolescents/youths, focusing on gender differences.

Methods

Participants (n = 840) completed the KIDSCREEN-27 to measure HRQoL at baseline and again after 3 years (n = 454). Follow-up assessment included the Coddington Life Events Scales (CLES) to measure LEs experiences in the previous 12 months. Respondents were categorized according to the amount of stress suffered. We calculated both the number of LEs and the Life Change Unit (LCU) score, a summary of the amount of stress inherent to the event and the time elapsed since occurrence. LEs were classified as desirable or undesirable, and family-related or extra-family. Effect sizes were calculated to evaluate changes in HRQoL. To assess the impact of LEs typologies, multiple linear regression models were constructed to evaluate their effect on HRQoL.

Results

Girls reported a mean 5.7 LEs corresponding to 141 LCUs, and boys 5.3 and 129, respectively. The largest impact of LEs on HRQoL was observed in the group of boys that reported to have lived more stress (third tertil of LCUs distribution). The linear association between LEs and HRQoL tended to be stronger among boys than girls, but the difference was not statistically significant. The effect on HRQoL was deemed important when undesirable events had been experienced. To have an important impact on HRQoL, 200 LCUs due to undesirable events were necessary in boys. In girls, slightly higher scores were necessary for a similar impact.

Conclusions

A moderate association was found between recent LEs and HRQoL, mainly among those who experienced several undesirable events that correspond to at least 200 LCUs. No gender differences were found in this association. Results may be useful for identifying adolescents with particular health risks, regardless of gender.

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.

Validation of the "World Health Organization Disability Assessment Schedule, WHODAS-2" in patients with chronic diseases

BACKGROUND

The WHODAS-2 is a disability assessment instrument based on the conceptual framework of the International Classification of Functioning, Disability, and Health (ICF). It provides a global measure of disability and 7 domain-specific scores. The aim of this study was to assess WHODAS-2 conceptual model and metric properties in a set of chronic and prevalent clinical conditions accounting for a wide scope of disability in Europe.

METHODS

1,119 patients with one of 13 chronic conditions were recruited in 7 European centres. Participants were clinically evaluated and administered the WHODAS-2 and the SF-36 at baseline, 6 weeks and 3 months of follow-up. The latent structure was explored and confirmed by factor analysis (FA). Reliability was assessed in terms of internal consistency (Cronbach's alpha) and reproducibility (intra-class correlation coefficients, ICC). Construct validity was evaluated by correlating the WHODAS-2 and SF-36 domains, and comparing known groups based on the clinical-severity and work status. Effect size (ES) coefficient was used to assess responsiveness. To assess reproducibility and responsiveness, subsamples of stable (at 6 weeks) and improved (after 3 moths) patients were defined, respectively, according to changes in their clinical-severity.

RESULTS

The satisfactory FA goodness of fit indexes confirmed a second order factor structure with 7 dimensions, and a global score for the WHODAS-2. Cronbach's alpha ranged from 0.77 (self care) to 0.98 (life activities: work or school), and the ICC was lower, but achieved the recommended standard of 0.7 for four domains. Correlations between global WHODAS-2 score and the different domains of the SF-36 ranged from -0.29 to -0.65. Most of the WHODAS-2 scores showed statistically significant differences among clinical-severity groups for all pathologies, and between working patients and those not working due to ill health (p < 0.001). Among the subsample of patients who had improved, responsiveness coefficients were small to moderate (ES = 0.3-0.7), but higher than those of the SF-36.

CONCLUSIONS

The latent structure originally designed by WHODAS-2 developers has been confirmed for the first time, and it has shown good metric properties in clinic and rehabilitation samples. Therefore, considerable support is provided to the WHODAS-2 utilization as an international instrument to measure disability based on the ICF model.

Discriminative capacity of the EQ-5D, SF-6D, and SF-12 as measures of health status in population health survey

PURPOSE

To compare the EQ-5D, SF-6D, and SF-12 in terms of their capacity to discriminate between groups defined by relevant socio-demographic and health characteristics in a general population survey.

METHODS

Data were obtained from the 2006 Catalan Health Interview Survey, a representative sample (n = 4,319) of the general population of Catalonia (Spain). Effect sizes (ES) and Receiver Operating Characteristic (ROC) curves were calculated to evaluate the instruments' capacity to distinguish between groups based on socio-demographic variables, recent health problems, perceived health, psychological distress, and selected chronic conditions.

RESULTS

All instruments showed a similar discriminative capacity between groups based on socio-demographic variables, recent medical visit (ES = 0.47-0.55), activity limitations (ES = 0.92-0.98), perceived health (ES = 0.97-1.33), and psychological well-being (ES = 1.17-1.57). Effect sizes between respondents with and without any of fourteen selected chronic conditions were large (0.76-1.04) for 4, moderate (0.55-0.74) for 8, and small (0.17-0.39) for two on the EQ-5D index. A similar pattern was observed for the SF-12 but ES were predominantly moderate (7 conditions) or small (6 conditions) on the SF-6D.

CONCLUSIONS

The EQ-5D and SF-12 were largely comparable in estimating the health burden of chronic conditions, recent health problems, and social inequalities. The SF-6D was less sensitive than the EQ-5D index and SF-12, particularly for physical chronic conditions.

Are attitudes towards mental health help-seeking associated with service use? Results from the European Study of Epidemiology of Mental Disorders

OBJECTIVE

To investigate the prevailing attitudes towards mental health help-seeking in Europe, their correlates, and whether these attitudes are associated with actual service use for mental health problems.

METHOD

Data were derived from the European Study of Epidemiology of Mental Disorders, a survey representative of the adult population of six countries: Belgium, France, Germany, Italy, the Netherlands and Spain (n = 8,796). The World Mental Health Composite International Diagnostic Interview was used to assess attitudes and DSM-IV diagnoses. The attitudes referred to beliefs that the respondents would seek professional help when faced with a serious emotional problem, would feel comfortable talking about personal problems with a professional, would not be embarrassed if friends knew about the professional help, and respondents' perceived effectiveness of mental health care.

RESULTS

Almost a third of the respondents held the view that professional care was worse than or equal to no help when faced with serious emotional problems. Female gender, being younger than 65 years of age, high income, living in Spain or Italy, presence of mood disorder and previous service use were associated with at least two of the four assessed attitudes towards mental health help-seeking. All four attitudes were significantly associated with mental health care use, also after adjustment for previous service use.

CONCLUSION

The low perceived effectiveness of professional care calls for serious action aiming to improve the visibility and credibility of the mental health care sector.

[Attitudes to the seeking of psychiatric help from mental health care professionals and actually seeking help: differences in Europe]

BACKGROUND

Little is known about attitudes to seeking help from mental health care professionals.

AIM

To investigate these attitudes and their correlates, and find out whether these attitudes are associated with the use of care services.

METHOD

Data were derived from the European Study of Epidemiology of Mental Disorders, a survey that is representative of the adult population of six countries (n = 8,796).

RESULTS

Almost a third of respondents were of the opinion that professional help was worse than or equivalent to no help at all, in relation to serious psychiatric problems. Females, respondents under the age of 65, with a higher income, living in Spain or Italy, with a mood disorder, and those who had previously sought mental health care, more often stated that they would seek professional help if beset by a serious mental health problem. All these groups, except for the younger than 65, also reported more often that they would feel comfortable discussing mental health problems with a professional or that they were receiving this kind of help. All these attitudes were associated with an increased chance that persons would use professional help if beset by mental health problems.

CONCLUSION

Definite steps need to be taken to increase the visibility and credibility of the mental health services.

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.

Perceived stigma among individuals with common mental disorders

BACKGROUND

Severe mental disorders are associated with social distance from the general population, but there is lack of data on the stigma reported by individuals with common mental disorders.

AIMS

To identify the correlates and the impact of stigma among individuals with common mental disorders.

METHODS

Cross-sectional, household interview survey of 8796 representing the non-institutionalized adults of Belgium, France, Germany, Italy, the Netherlands and Spain. Two perceived stigma questions (embarrassment and discrimination) were asked to respondents with significant disability. Health-related quality of life measured by the SF-12, work and activity limitation and social limitation were also assessed.

RESULTS

Among the 815 participants with a 12-month mental disorder and significant disability, 14.8% had perceived stigma. Stigma was significantly associated with low education, being married/living with someone and being unemployed. Perceived stigma was associated with decreased quality of life (SF-12 PCS score -4.65; p<0.05), higher work and role limitation and higher social limitation.

CONCLUSION

Individuals with mental disorders are more likely to report stigma if they have lower education, are married, or are unemployed. Perceived stigma is associated with considerably decrease in quality of life and role functioning. Health professionals and society at large must be aware of these findings, which suggest that fighting stigma should be a public health priority.

The epidemiology of eating disorders in six European countries: results of the ESEMeD-WMH project

Few data are available to estimate the prevalence of eating disorders (EDs) and their correlates in the community. This paper reports data on EDs obtained in the framework of the ESEMeD project, aimed at investigating the prevalence of non-psychotic mental disorders in six European countries (Belgium, France, Germany, Italy, the Netherlands and Spain), using a new version of the Composite International Diagnostic Interview. The ESEMeD study was a general population cross-sectional household survey. In total, 21,425 respondents aged 18 or older provided data for the project between January 2001 and August 2003. A subsample (N=4139) underwent a detailed investigation on EDs. Lifetime estimated prevalence of anorexia nervosa, bulimia nervosa, binge eating disorder, sub-threshold binge eating disorder, and any binge eating were 0.48%, 0.51%, 1.12%, 0.72%, and 2.15%, respectively, and they were 3-8 times higher among women for all EDs. However, since people under 18 were excluded from this study, our prevalence should be taken as lower-bound estimate of real frequencies. Indeed, cumulative lifetime prevalence analysis showed that the majority of eating disorders had their initial onset between 10 and 20 years of age. Role impairment and comorbidity with other mental disorders were highly common, yet only small proportions of patients with a lifetime diagnosis of EDs requested medical treatment. It still has to be proven whether early diagnostic identification and access to specialized care can reduce the burden caused by these disorders.

Perceived need for mental health care and service use among adults in Western Europe: results of the ESEMeD project

OBJECTIVE

This study assessed prevalence and correlates of perceived need for mental health care and its role in help seeking.

METHODS

Data were from general population surveys conducted for the European Study of the Epidemiology of Mental Disorders. The sample consisted of adults who screened positive for specific mood and anxiety symptoms in surveys conducted in Belgium, France, Germany, Italy, The Netherlands, and Spain (N=8,796). These individuals were further assessed for mental disorders with the Composite International Diagnostic Interview 3.0. Respondents who reported voluntary use of health services to address concerns with their "emotions or mental health" or who reported a need for services for mental health reasons were considered to have perceived need.

RESULTS

Nine percent of the total sample perceived some need for mental health care in the past 12 months. Among those who had a mental disorder in the past 12 months, 33% had perceived need. Psychiatric morbidity was the major determinant of perceived need. Among those with perceived need, older age, nonurban residence, and residence in Germany were positively associated with use of services.

CONCLUSIONS

Only a third of those with a 12-month mental disorder perceived need for mental health care. Psychiatric morbidity was the main determinant of perceived need; however, other factors (being female and being older) were associated with use of health services among those with perceived need. Among those with perceived need, it is important to increase access to care for the youngest and those living in urban areas.

DSM-IV personality disorders in the WHO World Mental Health Surveys

BACKGROUND

Little is known about the cross-national population prevalence or correlates of personality disorders.

AIMS

To estimate prevalence and correlates of DSM-IV personality disorder clusters in the World Health Organization World Mental Health (WMH) Surveys.

METHOD

International Personality Disorder Examination (IPDE) screening questions in 13 countries (n = 21 162) were calibrated to masked IPDE clinical diagnoses. Prevalence and correlates were estimated using multiple imputation.

RESULTS

Prevalence estimates are 6.1% (s.e. = 0.3) for any personality disorder and 3.6% (s.e. = 0.3), 1.5% (s.e. = 0.1) and 2.7% (s.e. = 0.2) for Clusters A, B and C respectively. Personality disorders are significantly elevated among males, the previously married (Cluster C), unemployed (Cluster C), the young (Clusters A and B) and the poorly educated. Personality disorders are highly comorbid with Axis I disorders. Impairments associated with personality disorders are only partially explained by comorbidity.

CONCLUSIONS

Personality disorders are relatively common disorders that often co-occur with Axis I disorders and are associated with significant role impairments beyond those due to comorbidity.

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.

Main traumatic events in Europe: PTSD in the European study of the epidemiology of mental disorders survey

A potentially traumatic event (PTE) contributes to trauma through its frequency, conditional probability of posttraumatic stress disorder (PTSD), and experience of other PTEs. A cross-sectional survey was conducted, enrolling 21,425 adults nationally representative of six European countries. Using the WHO-Composite International Diagnostic Interview, 8,797 were interviewed on 28 PTEs and PTSD. Prevalence of 12-month PTSD was 1.1%. When PTSD was present, the mean number of PTEs experienced was 3.2. In a multivariate analysis on PTEs and gender, six PTEs were found to be more traumatic, and to explain a large percentage of PTSD, as estimated by their attributable risk of PTSD: rape, undisclosed private event, having a child with serious illness, beaten by partner, stalked, beaten by caregiver.
