Is the prevalence of mental disorders a good measure of the need for services?

Is there a sexual difference in the relationship between sociodemographic information and the unmet dental care needs of disabled adults? An analysis from a national survey on persons with disabilities

BACKGROUND

Health status and health care utilization in people with disabilities are more likely to be poorer than those without disabilities. Previous studies showed that there were gaps in health-related conditions by sociodemographic information and gender but the association between these factors was not explained. This study aims to analyze the relationship between sociodemographic information and the unmet dental care needs of people with disabilities and explore the effect of sex within this relationship.

METHODS

The 2014 national survey on persons with disabilities was used, which separated unmet healthcare needs into medical and dental services. Unweighted samples included 6,824 people with disabilities in total and 6,555 (96.1% of the total, weighted as 6,583) people aged 20 years or older were selected as the study population. Frequency and chi-square tests were conducted to determine differences in the prevalence of unmet dental needs based on socioeconomic information, chronic diseases, and behavioral factors after applying weights. Logistic regressions were performed using an adjusted model with sociodemographic information, chronic diseases, and behavioral variables. All analyses were performed using IBM SPSS Statistics for Windows, version 26 (IBM Corp., Armonk, N.Y., USA).

RESULTS

Analysis of the sociodemographic factors related to unmet dental care revealed that they were higher in women and the elderly. In the fully adjusted logistic model, most of the sociodemographic information was significantly associated with unmet dental needs. The lowest group was 4.18 times more likely to have unmet dental care needs than the richest group, and females and middle-school graduates were almost twice as likely to experience unmet dental care needs than males and university graduates. Considering the interaction effect of age on unmet dental needs depending on sex differences, the odds ratio decreased for females with every annual increase in both models. Compared with the younger group, the older group showed a lower risk of having unmet dental needs, especially in females.

CONCLUSIONS

The factor most closely related to the unmet dental care needs of disabled people was socioeconomic problems. Its influence also differed by sex and age. Therefore, economic support measures and sexual differences are needed for long-term policy consideration to reduce the unmet dental care needs of disabled people.

Clinical Need, Perceived Need, and Treatment Use: Estimating Unmet Need for Mental Health Services in the Adult Population

Estimates of unmet need for mental health services in the adult population are too high because many recover without treatment. Untreated recovery suggests that individuals accurately perceive professional help as unnecessary and do not pursue it. If so, perceived need for treatment should predict service use/nonuse more strongly than the presence or seriousness of disorder. With National Comorbidity Survey-Replication data, respondents who recovered from prior disorder by the current year (N = 1,054) were compared to currently unrecovered respondents with less serious (N = 999) and more serious disorders (N = 294). Perceived need covaried positively with the presence and seriousness of disorder and linked to far higher odds of treatment use than disorder seriousness, supporting perceptual accuracy. Two-thirds of respondents who perceived a treatment need obtained care; only one-third had unmet need. Need perceptions may better estimate a treatment gap and prompt research on individuals' self-assessments and treatment decision-making.

Perceived unmet substance use and mental health care needs of acute care patients who use drugs: A cross-sectional analysis using the Behavioral Model for Vulnerable Populations

INTRODUCTION

The perceived unmet service needs of acute care-seeking people who use illegal drugs (PWUD) have been poorly documented, despite evidence of frequent hospital utilisation. This study applies the Behavioral Model for Vulnerable Populations to investigate correlates of unmet service needs in this subpopulation.

METHODS

Survey data from 285 PWUD at three urban Canadian acute care centres were examined. The survey included the Perceived Need for Care Questionnaire, which measured service seeking and care satisfaction for mental health and substance use concerns across seven types of services, as well as barriers to having care needs met. The Behavioral Model for Vulnerable Populations was applied in hierarchical setwise logistic regression to examine associations between high unmet service need and socio-structural predictors (i.e. predisposing, enabling and need factors).

RESULTS

Almost half (46%) of participants reported a high level of unmet service need, despite seeking services during the past year. Participants reporting recent criminal activity, adverse childhood experiences, transitory sleeping, having no community support worker, and meeting screening criteria for depression were more likely to report a high level of unmet service needs. Structural barriers to care (57%) were more commonly reported than motivational barriers (43%).

DISCUSSION AND CONCLUSIONS

Acute care-seeking PWUD experience high rates of unmet service needs for their mental health and substance use problems. Strategies that can help overcome structural barriers to care are necessary to help address the service needs of this population.

Lessons from a theory of change-driven evaluation of a global mental health funding portfolio

BACKGROUND

Given the underinvestment in global mental health to-date, it is important to consider how best to maximize the impact of existing investments. Theory of Change (ToC) is increasingly attracting the interest of funders seeking to evaluate their own impact. This is one of four papers investigating Grand Challenges Canada's (GCC's) first global mental health research funding portfolio (2012-2016) using a ToC-driven approach.

METHODS

A portfolio-level ToC map was developed through a collaborative process involving GCC grantees and other key stakeholders. Proposed ToC indicators were harmonised with GCC's pre-existing Results-based Management and Accountability Framework to produce a "Core Metrics Framework" of 23 indicators linked to 17 outcomes of the ToC map. For each indicator relevant to their project, the grantee was asked to set a target prior to the start of implementation, then report results at six-month intervals. We used the latest available dataset from all 56 projects in GCC's global mental health funding portfolio to produce a descriptive analysis of projects' characteristics and outcomes related to delivery.

RESULTS

12,999 people were trained to provide services, the majority of whom were lay or other non-specialist health workers. Most projects exceeded their training targets for capacity-building, except for those training lay health workers. Of the 321,933 people screened by GCC-funded projects, 162,915 received treatment. Most projects focused on more than one disorder and exceeded all their targets for screening, diagnosis and treatment. Fewer people than intended were screened for common mental disorders and epilepsy (60% and 54%, respectively), but many more were diagnosed and treated than originally proposed (148% and 174%, respectively). In contrast, the three projects that focused on perinatal depression exceeded screening and diagnosis targets, but only treated 43% of their intended target.

CONCLUSIONS

Under- or over-achievement of targets may reflect operational challenges such as high staff turnover, or challenges in setting appropriate targets, for example due to insufficient epidemiological evidence. Differences in delivery outcomes when disaggregated by disorder suggest that these challenges are not universal. We caution implementers, funders and evaluators from taking a one-size-fits all approach and make several recommendations for how to facilitate more in-depth, multi-method evaluation of impact using portfolio-level ToC.

Newcomers and Old Timers: An Erroneous Assumption in Mental Health Services Research

Based on the premise that treatment changes people in ways that are consequential for subsequent treatment-seeking, we question the validity of an unrecognized and apparently inadvertent assumption in mental health services research conducted within a psychiatric epidemiology paradigm. This homogeneity assumption statistically constrains the effects of potential determinants of recent treatment to be identical for former patients and previously untreated persons by omitting treatment history or modeling only main effects. We test this assumption with data from the 2001-2003 Collaborative Psychiatric Epidemiology Surveys; the weighted pooled sample is representative of noninstitutionalized U.S. adults (18+; analytic n = 19,227). Contrary to the homogeneity assumption, some associations with recent treatment are conditional on past treatment, including psychiatric disorder and race-ethnicity-measures of need and treatment disparities, respectively. We conclude that the widespread application of the homogeneity assumption probably masks differences in the determinants of recent use between previously untreated persons and former patients.

Estimating Service Needs for Alcohol and Other Drug Users According to a Tiered Framework: The Case of the São Paulo, Brazil, Metropolitan Area

OBJECTIVE

The purpose of this study was to estimate the need for population-level services for alcohol and other drug abuse in support of local planning.

METHOD

Data were drawn from a subsample of 2,942 interviewees from the São Paulo Megacity Study, which evaluated mental health in the general population (18 years and older) of residents in the São Paulo metropolitan area. This population was classified into five hierarchical categories of severity, making it possible to obtain estimates of need for services, combining evaluation criteria regarding drug and alcohol use and general and mental health comorbidities over the last 12 months. For the at-risk groups in this population, estimates from the Potential Demand for the Use of Services survey interviews over the last year were generated.

RESULTS

Concerning the need for services, 86.5% of the population (Tier 1) had no problems related to drug and alcohol use, 8.9% (Tier 2) used heavily, 3.5% (Tiers 3, 4, and 5) met criteria for substance abuse disorders, among whom 1.3% (Tiers 4 and 5) require more specialized and intensive treatment and support. The following estimates for the Potential Demand for the Use of Services were found: 25.5% (Tier 3) and 51.1% (Tier 4), indicating that a significant number of individuals met criteria for substance abuse disorders but did not perceive any need for professional help or neglected the help available.

CONCLUSIONS

In São Paulo there exists a large sector of the population that requires prevention strategies regarding the risks and harm resulting from alcohol and drug use, followed by a group requiring more specialized care. But a large number of substance users requiring specialized support did not use services and did not believe that they needed professional help.

Changes in percentages of perceived met needs for care over time in a Canadian longitudinal cohort

There is a paucity of research on determinants associated with changes in perceived met needs for care over time. This study used a longitudinal cohort to explore changes in percentages of perceived met needs over time and to identify its related determinants. Data analyzed was from a longitudinal community-based survey. A total of 150 participants received at least one type of help both at baseline and a 2-year follow-up. Multivariate analyses were used. Perceived met needs of the study sample slightly increased over time. People who had a higher percentage of met needs at baseline were less likely to have an increase in percentage of perceived met needs at the 2-year follow-up, whereas, those who had a higher value of wellbeing and an increase in the value of mental wellbeing over time, were associated with an increase in the percentage of met needs at the 2-year follow-up. Determinants associated with changes in percentages of perceived met needs could be the target for improving perceived need for mental health care. Findings of this study indicate the need for longitudinal studies in perceived need for mental health services.

Factors associated with health service utilisation for common mental disorders: a systematic review

BACKGROUND

There is a large treatment gap for common mental disorders (CMD), with wide variation by world region. This review identifies factors associated with formal health service utilisation for CMD in the general adult population, and compares evidence from high-income countries (HIC) with that from low-and-middle-income countries (LMIC).

METHODS

We searched MEDLINE, PsycINFO, EMBASE and Scopus in May 2016. Eligibility criteria were: published in English, in peer-reviewed journals; using population-based samples; employing standardised CMD measures; measuring use of formal health services for mental health reasons by people with CMD; testing the association between this outcome and any other factor(s). Risk of bias was assessed using the adapted Mixed Methods Appraisal Tool. We synthesised the results using "best fit framework synthesis", with reference to the Andersen socio-behavioural model.

RESULTS

Fifty two studies met inclusion criteria. 46 (88%) were from HIC. Predisposing factors: There was evidence linking increased likelihood of service use with female gender; Caucasian ethnicity; higher education levels; and being unmarried; although this was not consistent across all studies. Need factors: There was consistent evidence of an association between service utilisation and self-evaluated health status; duration of symptoms; disability; comorbidity; and panic symptoms. Associations with symptom severity were frequently but less consistently reported. Enabling factors: The evidence did not support an association with income or rural residence. Inconsistent evidence was found for associations between unemployment or having health insurance and use of services. There was a lack of research from LMIC and on contextual level factors.

CONCLUSION

In HIC, failure to seek treatment for CMD is associated with less disabling symptoms and lack of perceived need for healthcare, consistent with suggestions that "treatment gap" statistics over-estimate unmet need for care as perceived by the target population. Economic factors and urban/rural residence appear to have little effect on treatment-seeking rates. Strategies to address potential healthcare inequities for men, ethnic minorities, the young and the elderly in HIC require further evaluation. The generalisability of these findings beyond HIC is limited. Future research should examine factors associated with health service utilisation for CMD in LMIC, and the effect of health systems and neighbourhood factors.

Perceived Need for Mental Health Care: The Intersection of Race, Ethnicity, Gender, and Socioeconomic Status

Racial/ethnic minority populations underutilize mental health services, even in the presence of psychiatric disorder, and differences in perceived need may contribute to these disparities. Using the Collaborative Psychiatric Epidemiology Surveys, we assessed how the intersections of race/ethnicity, gender, and socioeconomic status affect perceived need. We analyzed a nationally representative sample of U.S. adults (18 years or older; N=14,906), including non-Latino whites, Asian Americans, Latinos, African Americans, and Afro-Caribbeans. Logistic regressions were estimated for the total sample, a clinical need subsample (meets lifetime diagnostic criteria), and a no disorder subsample. Perceived need varies by gender and nativity, but these patterns are conditional on race/ethnicity. Men are less likely than women to have a perceived need but only among non-Latino whites and African Americans. Foreign-born immigrants have lower perceived need than U.S.-born persons, only among Asian Americans. Intersectional approaches to understanding perceived need may help uncover social processes that lead to disparities in mental health care.

Racial/ethnic differences in perceived need for mental health care and disparities in use of care among those with perceived need in 1990-1992 and 2001-2003

OBJECTIVES

This study examines whether there are racial/ethnic differences in perceived need for mental health care among those with a mood and/or anxiety disorder in 1990-1992 and 2001-2003 in the US. Then among those with perceived need, we examine whether racial/ethnic disparities in use of mental health care existed in both time periods.

DESIGN

Using data from the 1990-1992 National Comorbidity Survey (NCS) and 2001-2003 National Comorbidity Survey - Replication (NCS-R), the study analyzes whether whites differed from blacks and Latinos in rates of perceived need among those with a mood and/or anxiety disorder in 1990-1992 and 2001-2003. Then among those with a disorder and perceived need, rates of mental health care use for whites are compared to black rates and Latino rates in within the 1990-1992 cohort and then within the 2001-2003 cohort.

RESULTS

There were no statistical racial/ethnic differences in perceived need in both time periods. Among those with perceived need in 1990-1992, there were no statistical racial/ethnic disparities in the use of mental health care. However, in 2001-2003, disparities in mental health care use existed among those with perceived need.

CONCLUSIONS

The emergence of racial/ethnic disparities in use of mental health care among those with a perceived need for care in 2001-2003 suggests that personal/cultural belief along with issues concerning access and quality of mental health care may create barriers to receiving perceived needed care. More research is needed to understand why these disparities emerged among those with perceived need in the latter time period and whether these disparities continue to exist in more recent years.

Mental health service use and need for care of Australians without diagnoses of mental disorders: findings from a large epidemiological survey

AIMS

While epidemiological surveys worldwide have found a considerable proportion of people using mental health services not to have a diagnosis of a mental disorder, with possible implications of service overuse, other work has suggested that most people without a current diagnosis who used services exhibited other indicators of need. The aims of the present study were, using somewhat different categorisations than previous work, to investigate whether: (1) Australians without a diagnosis of a mental disorder who used mental health services had other indicators of need; and (2) how rate and frequency of service use in Australia related to level of need, then to discuss the findings in light of recent developments in Australian Mental Health Policy and other epidemiological and services research findings.

METHODS

Data from the Australian National Survey of Mental Health and Wellbeing (NSMHWB) 2007 was analysed.

RESULTS

Most people using mental health services had evident indicators of need for mental health care (MHC), and most of those with lower evident levels of need did not make heavy use of services. Only a small proportion of individuals without any disorders or need indicators received MHC (4%). Although this latter group comprises a fair proportion of service users when extrapolating to the Australian population (16%), the vast majority of these individuals only sought brief primary-care or counselling treatment rather than consultations with psychiatrists. Access and frequency of MHC consultations were highest for people with diagnosed lifetime disorders, followed by people with no diagnosed disorders but other need indicators, and least for people with no identified need indicators. Limitations include some disorders not assessed in interview and constraints based on survey size to investigate subgroups defined, for instance, by socioeconomic advantage and disadvantage individually or by characteristics of area.

CONCLUSIONS

MHC for individuals with no recognised disorders or other reasonable need for such care may be occurring but if so is likely to be an area-specific phenomenon. Rather than revealing a large national pool of treatment resources being expended on the so-called 'worried well', the findings suggested a generally appropriate dose-response relationship between need indicators and service use. Definitive ascertainment of area-specific disparities in this national pattern would require a different survey approach. Government proposals for widespread introduction of stepped-care models that may seek to divert patients from existing treatment pathways need to be implemented with care and well informed by local data.

The role of consumer perspectives in estimating population need for substance use services: a scoping review

Background

A growing body of research assesses population need for substance use services. However, the extent to which survey research incorporates expert versus consumer perspectives on service need is unknown. We conducted a large, international review to (1) describe extant research on population need for substance use services, and the extent to which it incorporates expert and consumer perspectives on service need, (2) critically assess methodological and measurement approaches used to study consumer-defined need, and (3) examine the potential for existing research that prioritizes consumer perspectives to inform substance use service system planning.

Methods

Systematic searches of seven databases identified 1930 peer-reviewed articles addressing population need for substance use services between January 1980 and May 2015. Empirical studies (n = 1887) were categorized according to source(s) of data used to derive population estimates of service need (administrative records, biological samples, qualitative data, and/or quantitative surveys). Quantitative survey studies (n = 1594) were categorized as to whether service need was assessed from an expert and/or consumer perspective; studies employing consumer-defined need measures (n = 217) received further in-depth quantitative coding to describe study designs and measurement strategies.

Results

Almost all survey studies (96%; n = 1534) used diagnostically-oriented measures derived from an expert perspective to assess service need. Of the small number (14%, n = 217) of survey studies that assessed consumer’s perspectives, most (77%) measured perceived need for generic services (i.e. ‘treatment’), with fewer (42%) examining self-assessed barriers to service use, or informal help-seeking from family and friends (10%). Unstandardized measures were commonly used, and very little research was longitudinal or tested hypotheses. Only one study used a consumer-defined need measure to estimate required service system capacity.

Conclusions

Rhetorical calls for including consumer perspectives in substance use service system planning are belied by the empirical literature, which is dominated by expert-driven approaches to measuring population need. Studies addressing consumer-defined need for substance use services are conceptually underdeveloped, and exhibit methodological and measurement weaknesses. Further scholarship is needed to integrate multidisciplinary perspectives in this literature, and fully realize the promise of incorporating consumer perspectives into substance use service system planning.

Patterns and predictors of health service use among people with mental disorders in São Paulo metropolitan area, Brazil

AIMS

Important transformations in psychiatric healthcare (HC) delivery have been implemented in Latin America during the beginning of 21st century. However, information on current service uses patterns is scant, obstructing the estimates and proper planning of service needs for general population. The current investigation aims to describe patterns and estimates predictors of 12-month HC use by individuals with mental disorders in São Paulo metropolitan area, Brazil.

METHOD

Data are from São Paulo Mental Health Survey, a cross-sectional multistage representative study. Participants were face-to-face interviewed in their household, using a structured diagnostic interview, the World Mental Health Survey Initiative version of the Composite International Diagnostic Interview. A total of 5037 respondents, non-institutionalised, aged 18 years and older were interviewed. The response rate was 81.3%. We determined the percentages of individuals with 12-month DSM-IV anxiety, mood and substance disorders that received treatment in the 12 months prior to assessment in main service sectors (specialty mental health, general medicine, human services (HS), and complementary and alternative medicine). The number of visits and percentage of individuals who received treatment at minimally adequacy also was estimated. Multilevel regression controlled contextual variables that influenced the use of service and treatment adequacy.

RESULTS

Only 10.1% of respondents used some HC service in the 12 months prior to assessment for their psychiatric problems, including 3.9% of them being treated either by a psychiatrist, 3.5% by a non-psychiatrist mental health specialist, 3.3% by a general medical (GM) provider, 1.5% by a HS provider and 1.4% by a complementary and alternative medical provider. In general, those participants who received service in the mental health specialty sector reported more visits than those in the GM sector (median 3.9 v. 1.5 visits). The cases seen in specialty sector outnumber those visiting GM treatment in terms of minimally adequate treatment (54.6 v. 23.2%). The likelihood of receiving treatment was significantly greater among individuals diagnosed with any anxiety and mood disorder, presenting more severe disorders, and with possession of HC insurance.

CONCLUSIONS

The great majority of individuals with an active mental disorder in São Paulo were either untreated or insufficiently treated. Awareness and training programmes to GM professionals are advocated to improve recognition, care take and referral to specialty care when needed. Proper integration among HC sectors is recommended.

Help-seeking for mental health problems by employees in the Australian Mining Industry

BACKGROUND

The current study examined help-seeking behavior for mental health problems of employees in the mining industry.

METHODS

The research involved a paper-based survey completed by a cross-section of employees from eight coalmine sites. The research aimed to investigate the frequency of contact with professional and non-professional sources of support, and to determine the socio-demographic and workplace factors associated.

RESULTS

A total of 1,457 employees participated, of which, 46.6 % of participants reported contact with support to discuss their own mental health within the preceding 12 months. Hierarchical logistic regression revealed a significant contribution of workplace variables, with job security and satisfaction with work significantly associated with help-seeking behavior.

CONCLUSIONS

The results provide an insight into the help-seeking behaviour of mining employees, providing useful information to guide mental health workplace program development for the mining industry, and male-dominated industry more broadly.

Mental health services use among adults with or without mental disorders: Do development stages matter?

BACKGROUND

Mental health services (MHS) use is a complex behaviour that does not only concern individuals with current mental disorder. To date, few studies have examined age-related contextualisation of MHS use. Reasons for seeking help may vary according to development stages in adulthood.

AIMS

This study aimed to determine which predisposing, enabling and need factors, using Andersen's model, were associated with MHS use according to adult development stages among individuals with or without current psychiatric diagnosis.

METHODS

Three age groups were examined: 18- to 29-year-olds (n = 775), 30- to 49-year-olds (n = 1,560) and 50- to 64-year-olds (n = 960). Data were obtained from the Montreal Longitudinal Catchment Area Study. Bivariate and multivariate logistic regression analyses were conducted for each age group separately to determine which predisposing, enabling and need factors were associated with MHS use in the past 12 months.

RESULTS

For 18- to 29-year-olds, one enabling factor (Internet search) and two need factors (presence of major depressive disorder and number of stressful events) were positively associated with MHS use. For 30- to 49-year-olds, one predisposing factor (family history of mental disorder), four enabling factors (not currently working or in school, perceiving neighbourhood disorder, social cohesion and Internet searching) and one need factor (major depressive disorder) correlated with help seeking. For 50- to 64-year-olds, two predisposing factors (family history of mental disorder and higher self-perceived stigma), two enabling factors (low satisfaction in personal relationship and Internet searching) and one need factor (alcohol dependence) were associated with MHS use.

CONCLUSIONS

Factors associated with MHS use differ according to adult development stages. Programmes and policies should be based on age-related contextualisation to increase MHS use.

Diagnostic Issues and Controversies in DSM-5: Return of the False Positives Problem

The fifth revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) was the most controversial in the manual's history. This review selectively surveys some of the most important changes in DSM-5, including structural/organizational changes, modifications of diagnostic criteria, and newly introduced categories. It analyzes why these changes led to such heated controversies, which included objections to the revision's process, its goals, and the content of altered criteria and new categories. The central focus is on disputes concerning the false positives problem of setting a valid boundary between disorder and normal variation. Finally, this review highlights key problems and issues that currently remain unresolved and need to be addressed in the future, including systematically identifying false positive weaknesses in criteria, distinguishing risk from disorder, including context in diagnostic criteria, clarifying how to handle fuzzy boundaries, and improving the guidelines for "other specified" diagnosis.

Understanding service demand for mental health among Australians aged 16 to 64 years according to their possible need for treatment

BACKGROUND

To inform decisions about mental health resource allocation, planners require reliable estimates of people who report service demand (i.e. people who use or want mental health services) according to their level of possible need.

METHODS

Using data on 6915 adults aged 16-64 years in Australia's 2007 National Survey of Mental Health and Wellbeing, we examined past-year service demand among respondents grouped into four levels of possible need: (a) 12-month mental disorder; (b) lifetime but no 12-month mental disorder; (c) any other indicator of possible need (12-month symptoms or reaction to stressful event, or lifetime hospitalisation); (d) no indicator of possible need. Multivariate logistic regression analyses examined correlates of service demand, separately for respondents in each of levels 1-3.

RESULTS

Sixteen per cent of Australian adults reported service demand, of whom one-third did not meet criteria for a 12-month mental disorder (equivalent to 5.7% of the adult population). Treatment patterns tended to follow a gradient defined by level of possible need. For example, service users with a 12-month disorder received, on average, 1.6-3.9 times more consultations than their counterparts in other levels of possible need, and had 1.9-2.2 times higher rates of psychologist consultation. Service users with a lifetime but not 12-month disorder or any other indicator of need consumed a similar average number of services to people with mild 12-month mental disorders, but received relatively fewer services involving the mental health sector. Service demand was associated with increased suicidality and psychological distress in all levels of possible need examined, and with poorer clinical and functional status for those with 12-month or lifetime disorders.

CONCLUSIONS

Many Australians reporting service demand do not meet criteria for a current mental disorder, but may require services to maintain recovery following a past episode or because they are experiencing symptoms and significant psychological distress.

Family Influences on the Use of Mental Health Services among African Americans

We examine how families influence mental health service (MHS) utilization among African Americans by drawing on the concept of family ambivalence, which encompasses both family support and stress, and by placing utilization within the context of family histories of psychiatric disorder and treatment. Data are from the 2001-2003 National Survey of American Life, a nationally representative sample of African American adults (n = 3,149), including a clinical need subsample (n = 605) of respondents with a disorder. Negative family interactions have indirect positive effects on use of any MHS through need for care, whereas family social support lacks any effect. Although poor self-rated mental health (SRMH) is associated with greater utilization of any and specialty MHS given family histories of no disorder or treated disorder, utilization is low given a family history of untreated disorder, irrespective of SRMH. Screening for family histories of psychiatric disorder in primary care is recommended.

Unmet mental health care need 10-11 years after the 9/11 terrorist attacks: 2011-2012 results from the World Trade Center Health Registry

BACKGROUND

There is little current information about the unmet mental health care need (UMHCN) and reasons for it among those exposed to the World Trade Center (WTC) terrorist attacks. The purpose of this study was to assess the level of UMHCN among symptomatic individuals enrolled in the WTC Health Registry (WTCHR) in 2011-2012, and to analyze the relationship between UMHCN due to attitudinal, cost, and access factors and mental health symptom severity, mental health care utilization, health insurance availability, and social support.

METHODS

The WTCHR is a prospective cohort study of individuals with reported exposure to the 2001 WTC attacks. This study used data from 9,803 adults who completed the 2003-2004 (Wave 1) and 2011-2012 (Wave 3) surveys and had posttraumatic stress disorder (PTSD) or depression in 2011-2012. We estimated logistic regression models relating perceived attitudinal, cost and access barriers to symptom severity, health care utilization, a lack of health insurance, and social support after adjusting for sociodemographic characteristics.

RESULTS

Slightly more than one-third (34.2%) of study participants reported an UMHCN. Symptom severity was a strong predictor of UMHCN due to attitudinal and perceived cost and access reasons. Attitudinal UMHCN was common among those not using mental health services, particularly those with relatively severe mental health symptoms. Cost-related UMHCN was significantly associated with a lack of health insurance but not service usage. Access-related barriers were significantly more common among those who did not use any mental health services. A higher level of social support served as an important buffer against cost and access UMHCN.

CONCLUSIONS

A significant proportion of individuals exposed to the WTC attacks with depression or PTSD 10 years later reported an UMHCN, and individuals with more severe and disabling conditions, those who lacked health insurance, and those with low levels of social support were particularly vulnerable.

How Many People have Alcohol Use Disorders? Using the Harmful Dysfunction Analysis to Reconcile Prevalence Estimates in Two Community Surveys

Community prevalence rates of alcohol use disorders (AUDs) provided by epidemiological studies using DSM-based diagnostic criteria pose several challenges: the rates appear implausibly high to many epidemiologists; they do not converge across similar studies; and, due to low service utilization by those diagnosed as disordered, they yield estimates of unmet need for services so high that credibility for planning purposes is jeopardized. For example, two early community studies using DSM diagnostic criteria, the Epidemiologic Catchment Area Study (ECA) and the National Comorbidity Survey (NCS), yielded lifetime AUD prevalence rates of 14 and 24%, respectively, with NCS unmet need for services 19% of the entire population. Attempts to address these challenges by adding clinical significance requirements to diagnostic criteria have proven unsuccessful. Hypothesizing that these challenges are due to high rates of false-positive diagnoses of problem drinking as AUDs, we test an alternative approach. We use the harmful dysfunction (HD) analysis of the concept of mental disorder as a guide to construct more valid criteria within the framework of the standard out-of-control model of AUD. The proposed HD criteria require harm and dysfunction, where harm can be any negative social, personal, or physical outcome, and dysfunction requires either withdrawal symptoms or inability to stop drinking. Using HD criteria, ECA and NCS lifetime prevalences converge to much-reduced rates of 6 and 6.8%, respectively. Due to higher service utilization rates, NCS lifetime unmet need is reduced to 3.4%. Service use and duration comparisons suggest that HD criteria possess increased diagnostic validity. Moreover, HD criteria eliminate 90% of transient teenage drinking from disorder status. The HD version of the out-of-control model thus potentially resolves the three classic prevalence challenges while offering a more rigorous approach to distinguishing AUDs from problematic drinking.

Common mental disorder diagnosis and need for treatment are not the same: findings from a population-based longitudinal survey

BACKGROUND

Controversy exists regarding whether people in the community who meet criteria for a non-psychotic mental disorder diagnosis are necessarily in need of treatment. Some have argued that these individuals require treatment and that policy makers need to develop outreach programs for them, whereas others have argued that the current epidemiologic studies may be diagnosing symptoms of distress that in many cases are self-limiting and likely to remit without treatment. All prior studies that have addressed this issue have been cross-sectional. We examined the longitudinal outcomes of individuals with depressive, anxiety and substance use (DAS) disorder(s) who had not previously received any treatment. Method Data came from a nationally representative US sample. A total of 34 653 non-institutionalized adults (age ≥20 years) were interviewed at two time points, 3 years apart. DAS disorders, mental health service use and quality of life (QoL) were assessed at both time points.

RESULTS

Individuals with a DAS disorder who had not previously received any treatment were significantly more likely than those who had been previously treated to have remission of their index disorder(s) without subsequent treatment, to be free of co-morbid disorder(s) and not to have attempted suicide during the 3-year follow-up period (50.7% v. 33.0% respectively, p < 0.05). At wave 2, multiple linear regression demonstrated that people with a remission of their baseline DAS disorder(s) had levels of functioning similar to those without a DAS disorder.

CONCLUSIONS

Individuals with an untreated DAS disorder at baseline have a substantial likelihood of remission without any subsequent intervention.

Divorce and changes in the prevalence of psychotropic medication use: a register-based longitudinal study among middle-aged Finns

The annual prevalence of psychotropic medication use exceeds 10 percent in Europe and the United States, the prevalence being higher among the divorced than the married. We analysed changes in the three-month prevalence of psychotropic medication use (psycholeptics and psychoanaleptics excluding medication for dementia) by proximity to divorce, sex, medication type and socio-demographic characteristics, using register-data on 304,111 Finns between 25 and 64 years of age, of whom 23,956 divorced between 1995 and 2003 and 142,093 were continuously married from 1995 to 2004. Five years before divorce, men and women already displayed about one percentage point higher prevalence of psychotropic medication use than those who continued their marriage. The excess prevalence increased with approaching divorce and peaked six to nine months before divorce, reaching 7.3 percent (95% CI 6.8-8.0) among divorcing men and 8.1 percent (95% CI 7.5-8.8) among divorcing women. The peak was followed by an 18-month decline, after which the excess compared to the continuously married settled at nearly three percentage points. The excess was not due to being socio-economically disadvantaged, and socio-demographic factors also seemed to have few modifying effects. The changes in prevalence were largest for antidepressants and almost non-existent for antipsychotics. Our results suggest that the high prevalence of psychotropic medication use among the divorced results both from selective factors already present five years before divorce and the acute and long-term causal effects of becoming and being divorced. Counselling is needed for individuals in the process of divorce, rather than economic support for divorced individuals.

Factors associated with reported service use for mental health problems by residents of rural and remote communities: cross-sectional findings from a baseline survey

BACKGROUND

The patterns of health service use by rural and remote residents are poorly understood and under-represented in national surveys. This paper examines professional and non-professional service use for mental health problems in rural and remote communities in Australia.

METHODS

A stratified random sample of adults was drawn from non-metropolitan regions of New South Wales, Australia as part of a longitudinal population-based cohort. One-quarter (27.7%) of the respondents were from remote or very remote regions. The socio-demographic, health status and service utilization (professional and non-professional) characteristics of 2150 community dwelling residents are described. Hierarchical logistic regressions were used to identify cross-sectional associations between socio-demographic, health status and professional and non-professional health service utilization variables.

RESULTS

The overall rate of professional contacts for mental health problems during the previous 12 months (17%) in this rural population exceeded the national rate (11.9%). Rates for psychologists and psychiatrists were similar but rates for GPs were higher (12% vs. 8.1%). Non-professional contact rates were 12%. Higher levels of help seeking were associated with the absence of a partner, poorer finances, severity of mental health problems, and higher levels of adversity. Remoteness was associated with lower utilization of non-professional support. A Provisional Service Need Index was devised, and it demonstrated a broad dose-response relationship between severity of mental health problems and the likelihood of seeking any professional or non-professional help. Nevertheless, 47% of those with estimated high service need had no contact with professional services.

CONCLUSIONS

An examination of self-reported patterns of professional and non-professional service use for mental health problems in a rural community cohort revealed relatively higher rates of general practitioner attendance for such problems compared with data from metropolitan centres. Using a measure of Provisional Service Need those with greater needs were more likely to access specialist services, even in remote regions, although a substantial proportion of those with the highest service need sought no professional help. Geographic and financial barriers to service use were identified and perception of service adequacy was relatively low, especially among those with the highest levels of distress and greatest adversity.

Level of physical activity among children and adolescents in Europe: a review of physical activity assessed objectively by accelerometry

This study explored the proportion of European youth who are sufficiently active according to physical activity (PA) recommendations, based exclusively on objective assessment through accelerometers. A systematic electronic search of studies published up to March 2012 was conducted. PubMed was used to identify accelerometry-assessed PA studies that involved European youth. Within the 131 European studies, only 35 clearly reported the proportion of youth meeting the PA recommendations. Different thresholds lying between 1000 and 4000 counts/min (cpm) were used to define moderate-to-vigorous PA (MVPA). Overall, up to 100% of youth may be sufficiently active when using a threshold of approximately >1000-1500 cpm. With the most cited cut-off point (i.e. >2000 cpm), up to 87% of European youth might be considered physically active with reference to the current recommendations. Alternatively, with a cut-off point >3000 cpm, no more than 3-5% of them appeared to achieve these recommendations. The large discrepancy in outcomes released by accelerometer data is mainly due to the variety of cut-off points for MVPA among youth, hindering the definition of a clear goal towards PA promotion in Europe. Standardization of methods is urgently required.

Is mental health in the Canadian population changing over time?

OBJECTIVE

Mental health in populations may be deteriorating, or it may be improving, but there is little direct evidence to support either possibility. Our objective was to examine secular trends in mental health indicators from national data sources.

METHODS

We used data (1994-2008) from the National Population Health Survey and from a series of cross-sectional studies (Canadian Community Health Survey) conducted in 2001, 2003, 2005, and 2007. We calculated population-weighted proportions and also generated sex-specific, age-standardized estimates of major depressive episode prevalence, distress, professionally diagnosed mood disorders, antidepressant use, self-rated perceived mental health, and self-rated stress.

RESULTS

Major depression prevalence did not change over time. No changes in the frequency of severe distress were seen. However, there were increases in reported diagnoses of mood disorders and an increasing proportion of the population reported that they were taking antidepressants. The proportion of the population reporting that their life was extremely stressful decreased, but the proportion reporting poor mental health did not change.

CONCLUSIONS

Measures based on assessment of symptoms showed no evidence of change over time. However, the frequency of diagnosis and treatment appears to be increasing and perceptions of extreme stress are decreasing. These changes probably reflect changes in diagnostic practice, mental health literacy, or willingness to report mental health concerns. However, no direct evidence of changing mental health status was found.

Acculturation and perceived mental health need among older Asian immigrants

The demographic landscape of the United States is changing as the general population ages and the size of racial/ethnic minority groups grows. Most prior studies on mental health service use among Asians in America have overlooked older adults. A deeper understanding of the way acculturation factors impact help-seeking behaviors among older Asian Americans will inform behavioral health practice and program planners as they address the disparities affecting a diverse racial group. The California Health Interview Survey was used to examine the correlates of perceived mental health need among 980 older Asian immigrants. The study found that English proficiency and other covariates affected how Asian Americans perceived mental health need. Implications for understanding the help-seeking behaviors of older Asian immigrants are discussed.

Patterns of mental health care utilisation: distribution of services and its predictability from routine data

OBJECTIVES

Explore if a multi-dimensional analytic approach to routinely registered data provides a comprehensive way to characterise utilisation patterns, and to test if the patients' functional status is a predictor for the use of services.

METHOD

We linked register contact data during a two-year period, including all types of specialised mental health services, in the population of a Norwegian county. Cox regression was applied in the models for prediction of admission and readmission.

RESULTS

Great variability and complexity in patterns of utilisation were found, including multiple transitions between in-patient and out-patient statuses. The distribution of services was characterised by a small group of patients receiving a disproportionally large amount of resources. A majority of 77% appeared as out-patients only. Severity of symptoms as well as of dysfunction, as assessed by the split GAF-score, differentiated amongst utilisation groups. Both dimensions were significant predictors for admission. In contrast, only the severity of dysfunction predicted readmission.

CONCLUSION

Multi-dimensional data architecture and analytical perspectives can be applied to routine data, and should be used to analyse the diverse patterns of utilisation. Risk populations could be predicted by routinely registered information on functional status.

Attitudes toward help-seeking and duration of untreated mental disorders in a sectorized Athens area of Greece

The purpose of the present study was to investigate the association of opinions towards seeking psychiatric help with the duration of untreated mental disorders in a sectorized Athens area, served by a Community Mental Health Centre. The sample consisted of 134 individuals who had sought help from health or mental health non sectorized services prior to their visit to the Centre (group A) and 156 individuals whose visit to the Center was their first ever contact with a mental health service (group B). Opinions were assessed by the "Attitudes Toward Seeking Professional Psychological Help scale. Both groups were selected from a total of 1,008 individuals who had visited the Centre in four consecutive years. The duration of untreated mental disorders was found to be shorter in group A compared to group B. Males and females of both groups, who had visited the Centre in a time period shorter than 12 months since the onset of their psychopathology, expressed more positive views towards help-seeking, compared to their counterparts with longer duration of untreated mental disorder. The variables of gender (females), age at symptom onset (younger) and education (higher) predicted a shorter duration without psychiatric treatment and more positive views about the necessity of help-seeking. More severe type of diagnoses was associated with shorter durations before accessing care. Our findings underline that mental health awareness programs are clearly required in order to strengthen the early recognition of the need for help- seeking. The development of liaison and outreach activities could also prevent prolonged delays in psychiatric treatment.

Effects of sexual orientation and gender on perceived need for treatment by persons with and without mental disorders

OBJECTIVE

Research has shown that sexual minority groups have higher prevalence rates of psychiatric disorders (both mental and substance use disorders) and that they may seek treatment at higher rates than heterosexuals. However, relationships between treatment need and treatment use are not well understood. This study examined the relationship of sexual orientation and gender to perceived need for treatment and treatment use among individuals with and without mental or substance use disorders.

METHODS

Data were obtained from a probability sample of California residents that oversampled for persons from sexual minority groups (unweighted N=2,079). Bivariate analyses compared perceived treatment need and treatment use among groups defined by sexual orientation, gender, and presence of a mood, anxiety, or substance use disorder. Logistic regression models that controlled for sociodemographic factors were used to predict no use of treatment among those who perceived a need for it (unmet need), testing the interactive effects of gender, disorder, and sexual orientation.

RESULTS

Women from sexual minority groups had about half the odds of unmet treatment need as heterosexual women, but no interaction was found for men between sexual minority status and unmet need. Among individuals without any of the disorders assessed, men and women from sexual minority groups had lower odds of unmet need for treatment than heterosexual men and women.

CONCLUSIONS

Sexual orientation and gender differentially influenced treatment utilization, particularly among those who did not have a diagnosed disorder but perceived a need for treatment. Diagnostic criteria appear to be less relevant to understanding treatment use in sexual minority populations.

Subjective distress predicts treatment seeking for depression, bipolar, anxiety, panic, neurasthenia and insomnia severity spectra

OBJECTIVE

To examine correlates of mental health treatment seeking such as gender, diagnosis, impairment, distress and mastery.

METHOD

Longitudinal epidemiological data from the Zurich Study of common psychiatric syndromes, including unipolar and bipolar depression, panic, anxiety, neurasthenia and insomnia, were utilized. In longitudinal Generalized Estimating Equations, treatment seeking was regressed on measures of subjective distress and impairment, childhood family problems, mastery and number of comorbid diagnoses.

RESULTS

Approximately half of all treated participants across all six syndromes suffered from subthreshold disorders. Meeting full or subthreshold diagnostic criteria was associated with treatment seeking for insomnia. Being female was associated with treatment seeking for depression. The only variable highly and consistently associated with treatment seeking, across all syndromes, was subjective distress. Treated participants reported high levels of distress, work and social impairment in both diagnostic and subthreshold groups.

CONCLUSION

Subjective distress may be a better indicator of treatment seeking than symptom count.

Mental health care use in later life: results from a national survey of Canadians

OBJECTIVE

To estimate the proportion of older adults who have used mental health services in the past 12 months among those who meet the criteria for one or more Diagnostic and Statistical Manual of Mental Disorders (DSM), Fourth Edition, 12-month psychiatric disorders. We also examine the factors associated with mental health care use in this population.

METHOD

We used secondary data from the Canadian Community Health Survey: Mental Health and Well-Being (CCHS 1.2). We first estimated the proportion of adults aged 55 years and older who used a range of mental health services. Next, using logistic regression, we examined the relative contribution of predisposing, enabling, and need characteristics in predicting any service use in this population.

RESULTS

Among the 12 792 adults aged 55 years and older in the CCHS 1.2, 513 (4.23%, 95% CI 3.89% to 4.95%) met the criteria for at least one 12-month DSM-IV disorder. Among these respondents, 37% (95% CI 31% to 43%) saw at least one type of mental health care provider in the past 12 months. Visits to a general health care provider for mental health reasons were most common, followed by specialist care. Only psychological distress was significantly and positively associated with using mental health care services.

CONCLUSIONS

Over 60% of the older adults who met the criteria for a DSM-IV disorder were not using mental health care services. Social and demographic factors did not predict service use in this population.

Mediating effect of mental disorders in the pathway between life events and mental health services use: results from the Baltimore Epidemiologic Catchment Area study

This study assessed the role of some common mental health conditions as mediators in the pathway between suffering life events and using mental health services. The participants were from the Baltimore Epidemiologic Catchment Area cohort, interviewed in 1993 to 1996 and 2004 to 2005. Longitudinal data analysis was used to identify models with significant mediation. Only alcohol abuse/dependence disorder was a significant mediator in the pathway between suffering a life-threatening illness and using mental health services in a general medical setup. Female gender, being more than 65 years old, prior use of services and availability of health insurance were some of the factors that significantly predicted service use in that model. Some of other factors like social networks and social support, attitudes towards services, and stigma, may play a role in determining service use. Future research should investigate the role of such factors as mediators for mental health service use.

Examining critical health policy issues within and beyond the clinical encounter: patient-provider relationships and help-seeking behaviors

Among notable issues in health care policy and practice over the past 50 years have been those centered on the changing dynamics in clinical encounters, predominantly the relationship between physicians and patients and access to health care. Patient roles have become more active, diverse, long-term, and risk-based, while patient-provider relationships are multifaceted, less paternalistic, and more pivotal to health outcomes. Extensive literatures on help-seeking show how much social influences affect both undertreatment and inappropriate high utilization of health care. The challenge in trying to contain the growth of health care costs is two-fold: developing better ways of defining need for care and promoting better access for those who could benefit most from health care. Both of these strategies need to be considered in the context of addressing racial, ethnic, socioeconomic, and health status disparities. Rebuilding the primary care sector as a sociologically informed strategy and a key component of health care reform may optimize both health care delivery and patient outcomes.

From trauma to PTSD: beliefs about sensations, symptoms, and mental illness

Despite the ongoing debate about its legitimacy as a diagnostic entity, posttraumatic stress disorder (PTSD) continues to be the prevailing model for posttrauma suffering in Western societies. In this article, we examine how U.S. veterans came to conceptualize their posttrauma suffering as reflecting the mental disorder of PTSD. We describe the criteria veterans used to evaluate the potential clinical importance of their posttrauma reactions, and the process by which they came to label these reactions as PTSD. Difficulties that veterans experienced in evaluating their posttrauma reactions and in labeling them as PTSD mirror issues that have been raised about the diagnosis of PTSD in the professional literature.

Influence of gender, sexual orientation, and need on treatment utilization for substance use and mental disorders: findings from the California Quality of Life Survey

BACKGROUND

Prior research has shown a higher prevalence of substance use and mental disorders among sexual minorities, however, the influence of sexual orientation on treatment seeking has not been widely studied. We use a model of help-seeking for vulnerable populations to investigate factors related to treatment for alcohol or drug use disorders and mental health disorders, focusing on the contributions of gender, sexual orientation, and need.

METHODS

Survey data were obtained from a population-based probability sample of California residents that oversampled for sexual minorities. Logistic regression was used to model the enabling, predisposing, and need-related factors associated with past-year mental health or substance abuse treatment utilization among adults aged 18-64 (N = 2,074).

RESULTS

Compared with individuals without a diagnosed disorder, those with any disorder were more likely to receive treatment. After controlling for both presence of disorder and other factors, lesbians and bisexual women were most likely to receive treatment and heterosexual men were the least likely. Moreover, a considerable proportion of sexual orientation minorities without any diagnosable disorder, particularly lesbians and bisexual women, also reported receiving treatment.

CONCLUSION

The study highlights the need to better understand the factors beyond meeting diagnostic criteria that underlie treatment utilization among sexual minorities. Future research should also aim to ascertain the effects of treatment provided to sexual minorities with and without diagnosable disorders, including the possibility that the provision of such treatment may reduce the likelihood of their progression to greater severity of distress, disorders, or impairments in functioning.

Barriers in recognising, diagnosing and managing depressive and anxiety disorders as experienced by Family Physicians; a focus group study

BACKGROUND

The recognition and treatment of depressive- and anxiety disorders is not always in line with current standards. The results of programs to improve the quality of care, are not encouraging. Perhaps these programs do not match with the problems experienced in family practice. This study aims to systematically explore how FPs perceive recognition, diagnosis and management of depressive and anxiety disorders.

METHODS

focus group discussions with FPs, qualitative analysis of transcriptions using thematic coding.

RESULTS

The FPs considered recognising, diagnosing and managing depressive- and anxiety disorders as an important task. They expressed serious doubts about the validity and usefulness of the DSM IV concept of depressive and anxiety disorders in family practice especially because of the high frequency of swift natural recovery. An important barrier was that many patients have difficulties in accepting the diagnosis and treatment with antidepressant drugs. FPs lacked guidance in the assessment of patients' burden. The FPs experienced they had too little time for patient education and counseling. The under capacity of specialised mental health care and its minimal collaboration with FPs were experienced as problematic. Valuable suggestions for solving the problems encountered were made

CONCLUSION

Next to serious doubts regarding the diagnostic concept of depressive- and anxiety disorders a number of factors were identified which serve as barriers for suitablemental health care by FPs. These doubts and barriers should be taken into account in future research and in the design of interventions to improve mental health care in family practice.

Geographic patterns of frequent mental distress: U.S. adults, 1993-2001 and 2003-2006

BACKGROUND

Mental illnesses and other mental health problems often lead to prolonged, disabling, and costly mental distress. Yet little is known about the geographic distribution of such mental distress in the U.S.

METHODS

Since 1993, the CDC has tracked self-perceived mental distress through the Behavioral Risk Factor Surveillance System (BRFSS). In 2007 and 2008, analysis was performed on BRFSS data reported by 2.4 million adults from 1993-2001 and 2003-2006 to map and describe the prevalence of frequent mental distress (FMD)-defined as having >or=14 mentally unhealthy days during the previous 30 days-for all states and for counties with at least 30 respondents.

RESULTS

The adult prevalence of FMD for the combined periods was 9.4% overall, ranging from 6.6% in Hawaii to 14.4% in Kentucky. From 1993-2001 to 2003-2006, the mean prevalence of FMD increased by at least 1 percentage point in 27 states and by more than 4 percentage points in Mississippi, Oklahoma, and West Virginia. Most states showed internal geographic variations in FMD prevalence. The Appalachian and the Mississippi Valley regions had high and increasing FMD prevalence, and the upper Midwest had low and decreasing FMD prevalence.

CONCLUSIONS

Geographic areas were identified with consistently high and consistently low FMD prevalence, as well as areas in which FMD prevalence changed substantially. Further evaluation of the causes and implications of these patterns is warranted. Surveillance of mental distress may be useful in identifying unmet mental health needs and disparities and in guiding health-related policies and interventions.

Should gambling be included in public health surveillance systems?

This paper examines the question of whether indicators of pathological or disordered gambling should be included in current public health surveillance systems. Such inclusion can be justified in terms of the emerging associations between disordered gambling and the leading indicators of the risk for premature morbidity and mortality. Additional justification can be seen in terms of the potential of Internet gambling to increase the incidence of gambling disorders, particularly among younger and older populations. The paper describes characteristics of public health surveillance systems and recommends including gambling in such systems, on at least a provisional basis.

Beyond parity: primary care physicians' perspectives on access to mental health care

About two-thirds of primary care physicians (PCPs) reported in 2004-05 that they could not get outpatient mental health services for patients-a rate that was at least twice as high as that for other services. Shortages of mental health care providers, health plan barriers, and lack of coverage or inadequate coverage were all cited by PCPs as important barriers to mental health care access. The probability of having mental health access problems for patients varied by physician practice, health system, and policy factors. The results suggest that implementing mental health parity nationally will reduce some but not all of the barriers to mental health care.

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.

Major depression prevalence is very high, but the syndrome is a poor proxy for community populations' clinical treatment needs

OBJECTIVES

Some basic questions about the epidemiology of major depression (MD) remain open to debate and interpretation. Prevalence is a case in point. There have been claims that prevalence has been both over- and underestimated. This review is an attempt to reconcile this apparent contradiction.

METHOD

A literature search was carried out using MEDLINE. Articles were screened for relevance in 2 stages and bibliographies were examined to identify additional relevant publications.

RESULTS

The claim that prevalence has been overestimated appears to hinge on a concern that current diagnostic criteria fail to adequately differentiate between pathological and nonpathological mood disturbances. These arguments pertain to the validity of diagnostic criteria rather than to the prevalence of the syndrome that the criteria define. Conversely, the claim that prevalence has been underestimated is based on studies providing evidence of recall bias. If DSM-IV criteria are accepted as a diagnostic definition, MD prevalence is considerably higher than usually cited figures. However, the same literature indicates that the spectrum of severity is much broader than is usually acknowledged. The DSM-IV criteria appear to be a poor proxy for treatment need in community populations.

CONCLUSIONS

Increasing evidence suggests that MD is very common but also that DSM-IV and ICD-10 definitions capture such a broad spectrum of morbidity that they should not be regarded as de facto indicators of need, at least not in community populations.

How many forensic assertive community treatment teams do we need?

Despite the growing interest in forensic assertive community treatment (FACT), there is no standardized definition of FACT eligibility and no guidelines for how many FACT teams communities may need. In this brief report a definition for FACT eligibility is proposed-severe and persistent mental illness and three jail detentions in a one-year period-and modeled by using 5.5 years of administrative data (July 1, 1993, through December 31, 1998) from a large, urban county in the western United States. Findings suggest that large, urban communities should develop enough FACT teams to serve approximately 44% of their populations of persons with severe mental illness, or roughly .05% of their adult populations. Developing standardized eligibility criteria for FACT is an important first step toward developing its evidence base.

A spatial needs assessment of indigent acute psychiatric discharges in California

State and local mental health agencies have responsibility for the psychiatric care of Medicaid beneficiaries and indigents meeting pre-defined criteria. A significant uninsured caseload may prove draining to agencies and hospitals mandated to provide emergency services, resulting in limited access. A spatial needs assessment was conducted to find areas having a greater relative proportion of indigent psychiatric hospitalizations. Robust descriptive and inferential spatial techniques were applied to California 1999-2003 public-use Zip-Code-level hospital discharge data to create maps. These maps reveal a more stable view of spatial variation in the proportion of indigent discharges compared to all psychiatric discharges. Synthetic estimation techniques were also applied to U.S. Census data to estimate the proportion of severe mental illness among households at less than 200% poverty level compared to estimated mental illness among all households. Visually comparing these maps suggests areas of potential mismatch. These results and methods may inform public decision-making.

Depression and mental health visits to physicians--a prospective records-based study

Previous studies of access to care for depression have been based on cross-sectional surveys of self-reported use of mental health service use. As the recall of use may be differentially biased by mood states, inferences about how well persons with depression are accessing services in comparison to other groups may be misleading. Accordingly, we estimated the magnitude of the depression-use associations in relation to key covariates based on prospective records of mental health visits to physicians. The sample, N = 23,063, of persons 12 years and older, was drawn from the 1996/97 Ontario Health Survey and linked to their administrative mental health care records 24 months forward in time. We found that depression-use associations were in the expected direction but similar in magnitude to associations for gender and education unlike previous self-reported use surveys. Female gender was positively related to the use of a primary care physician but negatively related to seeing a psychiatrist as opposed to a primary care physician. Those who had attained higher levels of education were more likely to be seen by physicians than those with lower education levels. The meaning behind these findings bears further study as it may have implications for primary care reform and the design of future studies of access.
