Past-year use of outpatient services for psychiatric problems in the National Comorbidity Survey

Health service utilization for eating disorders: findings from a community-based study

BACKGROUND

Prior use of health services was examined in a community sample of women with bulimic-type eating disorders.

METHOD

Participants (n = 159) completed a structured interview for the assessment of eating disorder psychopathology as well as questions concerning treatment-seeking and type of treatment received.

RESULTS

Whereas a minority (40.3%) of participants had received treatment for an eating problem, most had received treatment for a general mental health problem (74.2%) and/or weight loss (72.8%), and all had used one or more self-help treatments. Where treatment was received for an eating or general mental health problem, this was from a primary care practitioner in the vast majority of cases. Only half of those participants who reported marked impairment associated with an eating problem had ever received treatment for such a problem and less than one in five had received such treatment from a mental health professional.

CONCLUSION

Women with bulimic-type eating disorders rarely receive treatment for an eating problem, but frequently receive treatment for a general mental health problem and/or for weight loss. The findings underscore the importance of programs designed to improve the detection and management of eating disorders in primary care.

Role of pregabalin in the treatment of generalized anxiety disorder

Generalized anxiety disorder (GAD) is a common, typically persistent, and disabling condition that is often not recognised, or treated in an evidence-based manner. Current pharmacological and psychological treatment approaches have a number of drawbacks, including a delay in onset of clinical effect, varying relative efficacy against psychological or somatic symptoms of anxiety, potentially troublesome adverse effects, and discontinuation symptoms on stopping treatment. Pregabalin is a structural analog of the inhibitory neurotransmitter gamma amino butyric acid (GABA) but is thought to exert its anxiolytic effects through binding in a state-dependent manner to the alpha-2-delta sub-unit of voltage-gated calcium channels in "over-excited" pre-synaptic neurones, reducing release of excitatory neurotransmitters such as glutamate and substance P. At fixed doses of 200 mg/day or greater, it has consistent proven efficacy in acute treatment of DSM-IV-defined GAD, with some evidence of an early onset of clinical effect, and of efficacy across psychological and somatic anxiety symptom clusters. A pregabalin dosage of 450 mg/day is efficacious in the prevention of relapse. There is at present no published direct comparison with an SSRI. The current known adverse effect profile and studies in healthy volunteers together suggest that pregabalin may have some tolerability advantages over benzodiazepines and venlafaxine, at least in short-term treatment.

Physical and mental comorbidity, disability, and suicidal behavior associated with posttraumatic stress disorder in a large community sample

OBJECTIVE

To assess if posttraumatic stress disorder (PTSD), recognized as a common mental disorder in the general population and veteran samples, has a unique impact on comorbidity, disability, and suicidal behavior (after adjusting for other mental disorders, especially depression).

METHODS

Data came from the Canadian Community Health Survey Cycle 1.2 (n = 36,984; age > or = 15 years; response rate 77%). All respondents were asked if they had been given a diagnosis of PTSD by a healthcare professional. A select number of mental disorders were assessed by the Composite International Diagnostic Interview. Chronic physical health conditions, measures of quality of life, disability, and suicidal behavior were also assessed.

RESULTS

The prevalence of PTSD as diagnosed by health professionals was 1.0% (95% CI = 0.90-1.15). After adjusting for sociodemographic factors and other mental disorders, PTSD remained significantly associated with several physical health problems including cardiovascular diseases, respiratory diseases, chronic pain conditions, gastrointestinal illnesses, and cancer. After adjusting for sociodemographic factors, mental disorders, and severity of physical disorders, PTSD was associated with suicide attempts, poor quality of life, and short- and long-term disability.

CONCLUSIONS

PTSD was uniquely associated with several physical disorders, disability, and suicidal behavior. Increased early recognition and treatment of PTSD are warranted.

The impact of post-traumatic stress disorder on treatment outcomes for heroin dependence

AIMS

To examine the impact of post-traumatic stress disorder (PTSD) on 2-year treatment outcomes for heroin dependence.

DESIGN

Prospective longitudinal study.

PARTICIPANTS

Data were obtained from a predominantly treatment seeking sample of 615 dependent heroin users who were followed-up at 3, 12 and 24 months (follow-up rates: 89%, 81% and 76%, respectively).

MEASUREMENTS

Outcomes examined include treatment retention and exposure, substance use, general physical and mental health and employment.

FINDINGS

Despite improvements in substance use, PTSD was associated with continued physical (beta - 1.69, SE 0.61, P < 0.01) and mental disability (beta - 2.07, SE 0.66, P < 0.01), and reduced occupational functioning (OR 0.67, 95% CI: 0.48-0.93) throughout the 2-year follow-up.

CONCLUSIONS

Although conventional treatment services are successful in producing improvements in substance use and associated disability, the disability associated with PTSD remains. An intervention targeting both heroin dependence and PTSD may help to improve the outcomes of those with PTSD.

Risk factor research and prevention for anxiety disorders: introduction to the special series on risk and prevention of anxiety pathology

In relation to treatment-related research in the United States, there is relatively little systematic effort focused on the combination of risk and prevention for anxiety pathology. This article broadly discusses risk factor research and prevention program development for anxiety psychopathology. The authors also specifically discuss papers in this special issue that are focused on these topics. Risk factor research should be used by clinical researchers to inform prevention programs, and reciprocally, prevention knowledge should be effectively utilized to drive new, clinically focused risk factor research.

Long-term social functioning after depression treated by psychiatrists: a review

OBJECTIVES

Numerous long-term studies of depression in psychiatric settings have shown a poor clinical outcome but little emphasis has been placed on psychosocial or functional outcome in studies to date. This article reviews published data on long-term social functioning after depression and considers why psychosocial recovery appears delayed compared with clinical recovery.

METHODS

Searches were carried out of the databases MEDLINE, PSYCHLIT and EMBASE for articles published from 1980 using keywords relating to social and functional outcomes of unipolar and bipolar depression. Review articles and relevant textbooks were also searched.

RESULTS

The few outcome studies published have described long-term functional impairment in the majority of patients but have been limited by methodological shortcomings. Psychosocial impairment tends to persist even after clinical remission from depression. Residual symptomatology after remission from depression may lead to enduring psychosocial impairment, as may subtle neurocognitive deficits. Axis I and II comorbidities predict a poor psychosocial outcome, but episodes of depression do not appear to lead to personality 'scarring'.

CONCLUSIONS

Future outcome studies need to focus on longitudinal social functioning. Full functional recovery after an episode of depression should be the goal of treatment as enduring residual symptoms lead to long-term psychosocial impairment.

Cognitive-behavioral therapy for anxiety in the elderly

Anxiety is a significant problem among the elderly. Due to complexities in the medical management of elderly patients, researchers and clinicians have sought psychosocial alternatives to pharmacotherapy in order to treat anxiety in the elderly. Cognitive-behavioral therapy (CBT) in particular has been investigated as a promising treatment. Research conducted to date has established that CBT produces significant improvement in anxiety symptoms among the elderly. However, there is some concern that CBT does not benefit elderly anxiety patients as much as it does younger patients. Investigators are seeking methods of augmenting or supplementing CBT in order to develop more effective treatments for anxiety in the elderly.

Trends in psychotropic medication use among U.S. adults

PURPOSE

To examine trends and prevalence of prescription psychotropic medication use among noninstitutionalized US adults.

METHODS

Prescription medication data from the third National Health and Nutrition Examination Survey (NHANES; 1988-1994; n = 20 050) and the 1999-2002 NHANES (n = 12 060), two nationally representative cross-sectional health examination surveys, were examined for persons aged > or =17 years.

RESULTS

The age-adjusted prevalence of psychotropic medication use increased from 6.1% in 1988-1994 to 11.1% in 1999-2002 (p < 0.001). This was due to more than a three-fold increase in antidepressant use (2.5%, 1988-1994 vs. 8.1%, 1999-2002 (p < 0.001)). Significant increases between time periods for antidepressant use were seen for all age, gender, and race-ethnic groups although increases were less pronounced for males than females and non-Hispanic blacks and Mexican Americans than non-Hispanic whites. Prevalence of use remained relatively constant from 1988-1994 to 1999-2002 for anxiolytic/sedative/hypnotic (ASH) medications (3.5-3.8%), antipsychotics (0.8-1.0%), and antimanic agents (0.3-0.4%). The age-adjusted prevalence of multiple psychotropic medication use increased from 1.2% in 1988-1994 to 3.1% in 1999-2002 (p < 0.001).

CONCLUSIONS

Psychotropic medication use among US adults increased since 1988-1994, specifically of antidepressants. Increases varied by gender and race-ethnicity indicating under-utilization for non-Hispanic blacks and Mexican Americans compared to non-Hispanic whites for both males and females.

Racial differences in mental health service utilization among low-income women

The authors present data on mental health outpatient services in non-specialty settings in a sample of low-income women by exploring service use in the general medical sector, specialty mental health/substance services, the human service sector, and self-help groups. Findings are reported from 668 African American and White women in the Mothers' Well-Being Study (MWS). The MWS measured a range of psychiatric and substance dependence disorders using the Composite International Diagnostic Interview, Version 2.1 (CIDI2.1). The MWS also gathered data regarding outpatient mental health service utilization. In the year preceding the study, 43.9% of the White respondents and 39.0% of the African American respondents had at least one of the mental health disorders measured in the MWS. There were no significant differences in the frequency of any of the disorders by race. However, White respondents with disorders received more treatment than African American women in the general medical sector. In the year prior to the interview, nearly a quarter (22.4%) of White women with any diagnosis received care in the general medical sector compared to only 9.1% of African American women. The racial disparity in mental health treatment in the general medical sector may indicate that African American low-income women are not receiving the same level of care as White women. The authors discuss the implications of this disparity and suggest ways of expanding access to care for African American women in the general medical setting.

There are no association between IgE levels and symptoms of anxiety and depression in the adult female general population. The Hordaland Health Study (HUSK)

There are multiple reports of increased prevalence of anxiety and depression in patients with asthma, eczema and rhinitis. Suggested biological mechanisms underlying these associations most commonly involve IgE. However, the association between anxiety/depression and IgE has hardly been studied, and the aim of the present study will therefore be to examine the hypothesized association between anxiety/depression and IgE in a general adult female population. A sub-sample of 374 female participants in a population-based general health study in Norway (the Hordaland Health Study) with participation rate 70% was screened for total and allergen-specific IgE. Anxiety and depression were measured employing the Hospital Anxiety and Depression Scale (HADS). This design ensured adequate statistical power, and the population-approach ensured satisfactory variance in both IgE and anxiety/depression. No association between case level or symptom load of anxiety/depression and total or allergen-specific IgE was found. Non-significant tendencies were both positive and negative. This finding was robust across continuous and categorical statistical approaches. Our finding does not question the commonly reported associations between anxiety/depression and asthma, rhinitis and eczema. We do, however, question the relevance of IgE as an aetiological factor in the biological chain underlying these associations.

The Mood Spectrum Self-Report: validation and adaptation into Spanish

This study explores the psychometric properties of the Spanish adaptation of the Mood Spectrum Self-Report (MOODS-SR), an instrument designed to assess a broad range of manifestations of mood psychopathology. A total of 71 Spanish subjects participated: 49 outpatients who met criteria for a mood disorder or generalized anxiety disorder, and 22 normal controls. The instrument proved to have good internal consistency and test-retest reliability. Significant positive correlations were found between the depressive subdomains of the questionnaire and the Beck Depression Inventory, as well as between the manic-hypomanic subdomains and the Clinician-Administered Rating Scale for Mania. Clinical subjects displayed higher mean scores than normal subjects in all domains, and patients with bipolar disorder displayed higher scores than patients with unipolar disorder in the Manic component, particularly in the Energy and the Cognition subdomains. Differences between patients with generalized anxiety and mood disorders were small. The former, however, did not differ from normal controls in several subdomains, whereas patients with mood disorders did.

Impact of program services on treatment outcomes of patients with comorbid mental and substance use disorders

OBJECTIVE

This study examined the outcomes of individuals with co-occurring disorders who received drug treatment in programs that varied in their integration of mental health services. Patients treated in programs that provided more on-site mental health services and had staff with specialized training were expected to report less substance use and better psychological outcomes at follow-up.

METHODS

Participants with co-occurring disorders were sampled from 11 residential drug abuse treatment programs for adults in Los Angeles County. In-depth assessments of 351 patients were conducted at treatment entry and at follow-up six months later. Surveys conducted with program administrators provided information on program characteristics. Latent variable structural equation models revealed relationships of patient characteristics and program services with drug use and psychological functioning at follow-up.

RESULTS

Individuals treated in programs that provided specific dual diagnosis services subsequently had higher rates of utilizing mental health services over six months and, in turn, showed significantly greater improvements in psychological functioning (as measured by the Brief Symptom Inventory and the RAND Health Survey 36-item short form) at follow-up. More use of psychological services was also associated with less heroin use at follow-up. African Americans reported poorer levels of psychological functioning than others at both time points and were less likely to be treated in programs that provided mental health services.

CONCLUSIONS

Study findings support continued efforts to provide specialized services for individuals with co-occurring disorders within substance abuse treatment programs as well as the need to address additional barriers to obtaining these services among African Americans.

Ready! Fire! Aim! The Status of Psychological Debriefing and Therapeutic Interventions: In the Work Place and after Disasters

Psychological debriefing (PD) is a brief, short-term intervention aimed at mitigating long-term distress and preventing the emergence of posttraumatic stress. In recent years, it has become a ubiquitous intervention, one which has evolved as almost prescriptive following harrowing events and grew through a practical need to offer assistance to those who are exposed to severe trauma. Despite disturbing data from the recent refereed literature of psychology, it is still referred to as the “standard of care” for disaster and crisis response and its use in many quarters continues. This article critically reviews the evidence for and against its use and outlines the weaknesses in the research. The emphasis of this review is on the appropriateness of debriefing in organizations. This article also proposes a set of hypothesized constructs that may, in part, be responsible for the paradoxical effects found in some outcome studies on debriefing. Guidelines are also proposed to help organizations and professionals react appropriately using evidence-based interventions.

Remission of psychiatric symptoms among drug misusers after drug dependence treatment

The study investigates changes in psychiatric symptoms after drug dependence treatment, and relationships between pretreatment problems, illicit drug use, treatment retention, and changes in psychiatric symptoms. The sample comprised 662 drug-dependent adults recruited at admission to treatment in residential rehabilitation programs (15 agencies) or outpatient methadone treatment (16 methadone maintenance programs and 15 methadone reduction programs). Using a longitudinal, prospective cohort design, data were collected by structured interviews at intake to treatment and at 1-month and 6-month follow-ups. Reductions were found in a range of psychiatric symptoms after admission to drug dependence treatment and among patients treated in outpatient and in residential programs. These reductions occurred rapidly (during the first month) and were maintained at subsequent follow-up. At intake to treatment, 39% of the residential sample met criteria for psychiatric caseness. This figure dropped to 3% at both 1-month and 6-month follow-up. Among methadone patients, 15% met criteria for psychiatric caseness at intake, and this dropped to 5% at 1 month and 3% at 6 months. Improvement in psychiatric symptoms was positively related to treatment retention. Some of the psychiatric symptoms presented by drug-dependent patients at admission to treatment are associated with drug misuse and show rapid remission after substance misuse treatment.

Twelve-month and lifetime health service use in Te Rau Hinengaro: The New Zealand Mental Health Survey

OBJECTIVE

To estimate the 12 month and lifetime use of health services for mental health problems.

METHOD

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

RESULTS

Of the population, 13.4% had a visit for a mental health reason in the 12 months before interview. Of all 12 month cases of mental disorder, 38.9% had a mental health visit to a health or non-health-care provider in the past 12 months. Of these 12 month cases, 16.4% had contact with a mental health specialist, 28.3% with a general medical provider, 4.8% within the human services sector and 6.9% with a complementary or alternative medicine practitioner. Most people with lifetime disorders eventually made contact if their disorder continued. However, the percentages seeking help at the age of onset were small for most disorders and several disorders had large percentages who never sought help. The median duration of delay until contact varies from 1 year for major depressive disorder to 38 years for specific phobias.

CONCLUSIONS

A significant unmet need for treatment for people with mental disorder exists in the New Zealand community, as in other comparable countries.

Pregabalin: in the treatment of generalised anxiety disorder

Pregabalin, the pharmacologically active S-enantiomer of 3-aminomethyl-5-methyl-hexanoic acid, is a structural analogue of GABA, although it is not active at GABA receptors, nor does it acutely alter GABA uptake or degradation.black triangle Pregabalin binds with high affinity to the alpha2-delta subunit protein of voltage-gated calcium channels in CNS tissues and acts as a presynaptic modulator of the excessive release, in hyperexcited neurons, of various excitatory neurotransmitters. Binding of pregabalin to the alpha2-delta subunit appears necessary for its demonstrable anxiolytic, analgesic and anticonvulsant activities in animal models.black triangle Oral pregabalin, typically at dosages of 300-600 mg/day, was superior to placebo and similar to lorazepam 6 mg/day, alprazolam 1.5 mg/day and venlafaxine 75 mg/day in improving anxiety and depressive symptoms in patients with moderate-to-severe generalised anxiety disorder (GAD). Pregabalin had a rapid onset of anxiolytic activity relative to alprazolam and venlafaxine, which was evident after 1 week. Additionally, pregabalin (initial dosage 450 mg/day) was effective for the prevention of relapse of GAD over 34 weeks. Pregabalin was well tolerated during dosage escalation to fixed dosages (maximum 600 mg/day) over 7 days. Dizziness and somnolence, usually of mild to moderate severity, were the most common adverse events.black triangle The drug was not associated with a clinically significant medication withdrawal syndrome during a 1-week taper following 4 or 6 weeks' double-blind treatment.

Cluster B and C personality traits, symptom correlates, and treatment utilization in postacute schizophrenia

Unusually high levels of Cluster B and C personality traits have been observed in schizophrenia. While these have been linked to poorer function, less clear is the association of these personality traits with symptoms and service utilization. To examine this issue, 46 participants with schizophrenia or schizoaffective disorder were administered the Millon Clinical Multiaxial Inventory, Third Edition, and the Positive and Negative Syndrome Scale, and an inventory was taken of medical and psychiatric service utilization. Two sets of multiple regression analyses using Cluster B and C traits to predict treatment utilization and symptoms revealed that emotional discomfort symptoms were significantly related to level of borderline traits. Higher levels of positive symptoms were linked with more avoidant traits and fewer dependent traits. Higher levels of negative symptoms were linked with greater avoidant traits. Service utilization was predicted by borderline, antisocial, and avoidant traits. Implications for rehabilitation and treatment are discussed.

Treating incarcerated women: gender matters

Research on incarcerated women has shown they have a high degree of comorbid psychopathology, including substance dependence, posttraumatic stress disorder (PTSD), antisocial personality disorder (ASPD), and major depression. Incarcerated women differ from their community peers by having more symptoms related to addiction, ASPD, and PTSD. At the same time, incarcerated women are every bit as likely as incarcerated men to be dependent on drugs and almost as likely to be dependent on alcohol. What emerges is a picture of the incarcerated woman far more likely to have had traumatic experiences, including early sexual and physical abuse, than her male peers but every bit as likely to have substance dependence and, in some correctional populations (eg, sentenced felons), antisocial personality disorder. Central to the discussion of how best to treat female offenders is the need to address how programs would best be structured for women with severe substance dependence, substantial trauma histories, and personality pathology, including ASPD. Incarcerated women are a population with complex medical and mental health needs and are likely to be high users of services within the correctional system. This poses challenges to a system already stretched thin in caring for these complex inmates. This article emphasizes that gender differences need to be appreciated, and that service delivery to male and female inmates needs to be structured with gender in mind. The article recommends case management, treatment in highly structured therapeutic communities, and emphasizing abstinence from substances and development of skill sets to engage in healthy relationships.A major future challenge lies in researching treatment interventions for women in the correctional system. There are few existing trials of treatment efficacy and, as previously noted, the incarcerated female population differs from populations of incarcerated men and women in the community. Opiate-dependent women undergoing treatment in the community may prove to be a reasonable comparison group in beginning to develop evidence-based treatment for female offenders in prisons and jails. Ultimately, the development of services for incarcerated women will consider gender, race, and psychopathology in determining treatment setting and modalities. We are on new ground. It is a promising and exciting time to be involved with treatment of female offenders.

Risk-factor research and prevention programs for anxiety disorders: A translational research framework

The aim of the present essay is to discuss the interconnection between risk-factor research and prevention program development for panic-spectrum psychopathology. We argue that prevention of panic-spectrum psychopathology specifically, and anxiety disorders more generally, is likely to be best advanced through active, systematic translation of basic, risk-factor research. After operationalizing key terminology, we present some exemplar risk-factor candidates for panic-spectrum psychopathology, summarize research related to their role as risk-factors for panic problems, and link this discussion to risk-factor nomenclature. We then present a translational framework for extrapolating extant knowledge on these and other potential risk-factors for panic-spectrum psychopathology with respect to the development of preventative interventions. The proposed translational framework is intended to describe a forward-feeding process by which risk-factor research could be used by clinical researchers to inform prevention programs; and reciprocally, how such prevention knowledge could be most effectively utilized to drive new, clinically focused risk-factor research.

Worker productivity and outpatient service use after the September 11th attacks: results from the New York City terrorism outcome study

BACKGROUND

Research has shown that the terrorist attacks in New York City (NYC) on September 11, 2001 had an impact on the psychological status of area residents. Since a major goal of many terrorist attacks is to also adversely affect local socioeconomic activities, the long-term impact of exposure to terrorist attacks on productivity and outpatient service utilization among workers in NYC is assessed.

METHODS

The impact of the World Trade Center disaster (WTCD) among 1,167 workers in NYC is examined using a prospective cohort design. The study included measures of WTCD exposures, stressful life events, other traumatic events, post-traumatic stress disorder (PTSD), and depression, assessed at 1 year and 2 years post-disaster.

RESULTS

Bivariate analyses suggest that exposure to WTCD events is associated with high productivity loss at baseline, but not consistently at follow-up. Both PTSD and depression are associated with lower quality workdays at baseline and follow-up, but depression is more consistently associated with high work loss and medical service use. In multivariate analyses, WTCD exposure is associated with productivity loss at baseline, but less consistently at follow-up. At baseline, depression and history of traumatic events are associated with lower quality workdays and negative life events with greater workdays lost. Multivariate analyses at follow-up indicated that experiencing negative life events is associated with higher workdays lost and lower quality workdays and that PTSD is associated with lower quality workdays. Similar regression models suggested that increased outpatient service use is associated with depression and lifetime traumatic events at baseline and with negative life events at follow-up.

CONCLUSION

This study suggests that while the WTCD had an impact on worker productivity within the first year after the attack, this did not generally persist, especially after controlling for baseline status. Having PTSD or experiencing stressful life events at follow-up, however, is associated with lower quality workdays, even after controlling for baseline status.

Mental health service use among American Red Cross disaster workers responding to the September 11, 2001 U.S. terrorist attacks

In this article, we explored 1) the extent of mental health (MH) service use by American Red Cross disaster relief workers, both before (lifetime) and 1 year after the September 11, 2001 terrorist attacks, and 2) demographic, disaster and MH variables predicting (1-year) post-September 11 MH service use in this population. A sample of 3015 Red Cross disaster workers was surveyed 1 year after the attacks, regarding demographic characteristics, MH service use before and since the attacks, and posttraumatic stress disorder (PTSD) symptoms. Findings revealed that while 13.5% used MH services before the attacks, 10.7% used services after. Variables increasing the likelihood of MH service use after the attacks included the following: no previous MH treatment, younger age, being divorced/widowed, and higher PTSD intrusion or hyperarousal symptoms. Findings support other recent research on MH service use after the September 11 attacks.

Escitalopram in the treatment of generalized anxiety disorder

The selective serotonin reuptake inhibitor escitalopram is the active enantiomer of citalopram and has proven efficacy in the treatment of major depression, panic disorder and social phobia. Accumulating data indicate that it is also efficacious in the treatment of patients with generalized anxiety disorder. This drug profile summarizes the current evidence-base for the treatment of generalized anxiety disorder, describes the findings of a series of randomized placebo-controlled and comparator-controlled trials of escitalopram, examines the strengths and weaknesses of current treatment approaches and considers potential new therapies for the treatment of this common, chronic and impairing anxiety disorder. In summary, escitalopram is effective and well tolerated in both the short- and long-term treatment of generalized anxiety disorder, and has advantages over benzodiazepines and the selective serotonin reuptake inhibitor paroxetine.

Where have they been? Service use of regular substance users with and without abuse and dependence

OBJECTIVE

To present lifetime rates of service use for psychological and substance use related problems among regular substance users and to examine factors associated with service use.

METHOD

Data come from a prospective-longitudinal, epidemiological study of a community sample of adolescents and young adults (n = 2548, age 14-24 years at baseline) in Munich, Germany. The Munich-Composite International Diagnostic Interview (M-CIDI) was used at baseline and at two follow-ups to assess substance use and service use.

RESULTS

Cumulated lifetime incidence of any substance abuse or dependence was 43.7%. Of those with abuse and dependence 23% had ever used any services for psychological or substance use related problems. Illicit substance users especially those with dependence had the highest rates of lifetime service use (52.1%). Psychotherapists and counseling services were contacted most frequently among regular substance users over their lifetimes. Utlilisation rates of substance abuse services were low (2%). Comorbid anxiety disorders and distressing life events were associated with increased lifetime service use.

CONCLUSIONS

Only a minority of adolescents and young adults with substance use disorders have ever sought professional help. Specialized substance abuse services play only a minor role. The core role of psychotherapists and non-substance abuse specialized services needs critical research attention. Linkages between psychotherapists and the substance use service system should be strengthened to detect and intervene at early developmental stages of abuse and dependence.

What should non-US behavioral health systems learn from the USA?: US behavior health services trends in the 1980s and 1990s

Several countries, such as the USA, inadvertently created a different behavioral health payment system from the rest of medicine through the introduction of diagnostic-related group exemptions for psychiatric care. This led to isolation in the administration and delivery of care for patients with mental health and substance abuse disorders from other medical services with significant, yet unintended, consequences. To insure an efficient and effective health-care system, it is necessary to recognize the problems introduced by segregating behavioral health from the rest of medical care. In this review, the authors assess trends in behavioral health services during the last two decades in the USA, a period in which independently managed behavioral health care has dominated administrative practices. During this time, behavioral health has been an easy target for aggressive cost cutting measures. There have been no clinically significant improvements in the number of adults receiving minimally adequate treatment or in the percentage of the population with behavior health problems receiving psychiatric care with the possible exception of depression. While decreased spending for behavioral health services has been well documented during this period, these savings are offset by costs shifted to greater medical service use with a net increase in the total cost of health care. Targeting behavioral health for reduction in health-care spending through independent management, starting with diagnostic procedure code or diagnostic-related group exemption may not be the wisest approach in addressing the increasing fiscal burden that medical care is placing on the national economy.

The burden of psychological symptoms in UK Armed Forces

OBJECTIVE

To assess the prevalence of psychological symptoms during periods of relatively low deployment activity and the factors associated with each psychological health outcome.

METHODS

A survey of 4500 randomly selected UK service personnel was carried out in 2002. The questionnaire included the General Health Questionnaire (GHQ-12), the post-traumatic stress disorder checklist (PCL), 15 symptoms and an assessment of alcohol intake.

RESULTS

A total of 20% were above cut-offs for GHQ-12, 15% for symptoms, 12% for alcohol intake and 2% for PCL. Gender, age, excessive drinking and smoking were independently associated with most outcomes of interest. Number of deployments was independently associated with multiple symptoms and excessive drinking. High post-traumatic stress disorder score was more frequent in the Army and in lower ranks.

CONCLUSIONS

Psychological symptoms are highly prevalent in UK Armed Forces. Many risk factors are associated with measures of psychological ill-health.

Obstacles for rural American Indians seeking alcohol, drug, or mental health treatment

The purpose of this study was to identify factors associated with 4 clusters of obstacles (self-reliance, privacy issues, quality of care, and communication and trust) to mental health and substance abuse treatment in 3 treatment sectors for residents of 3 reservations in the United States. Participants (N=3,084) disclosed whether they had sought treatment for emotional, drug, or alcohol problems in the past year and, if so, whether they had faced obstacles in obtaining care from Indian Health Services, tribal services, and other public or private systems. Correlates of these obstacles included negative social support, instrumental social support, utility of counselors, utility of family doctors, treatment sector, treatment type, diagnosis of an anxiety disorder, and tribe.

Common-sense descriptions of depression as social representations

BACKGROUND

Major depression is such a prevalent illness worldwide that practically everyone has either direct or indirect experience of it. It is important, then, from both practical and theoretical points of view, to examine this particular experience and related conceptions.

AIM

Drawing on the theory of social representations, this research set out to examine the ways in which people define depression in terms of the symptoms they attribute to people they know personally and consider to suffer from depression.

METHOD

A group of adult participants (n = 117) were instructed to think of an individual whom they knew personally and considered to suffer from depression, to indicate the age and gender of the person, and to describe his/her symptoms.

RESULTS

A great majority of the female participants thought of a female, while the male participants thought of male and female target persons quite evenly. The symptoms attributed to depression with fair unanimity included fatigue and decreased capacity to work, to concentrate, to make decisions and to take part in hobbies. The descriptions of the depressive person were quite unanimously distinguished from the signal symptoms attaching to schizophrenia. The descriptions varied according to the characteristics of the target individuals, and their gender and age in particular, rather than the characteristics of the participants.

CONCLUSION

People have perceptive personal experiences of depression, which are guided by socially shared interpretative frameworks.

Personality correlates of outpatient mental health service utilization: findings from the U.S. national comorbidity survey

OBJECTIVE

The present paper investigated the relationships between several personality constructs and the use of outpatient mental health services.

METHODS

Respondents were from the National Comorbidity Survey (NCS) Part II data set and included those with a past-year mood, anxiety, alcohol/substance use disorder (n=1750). Bivariate logistic regressions were used to examine associations between participants' self-reports of personality traits and outpatient mental health service utilization. Similar multivariate analyses were used to investigate these associations after adjusting for sociodemographic variables and the presence of psychiatric disorders and their comorbidity.

RESULTS

The bivariate and multivariate analyses revealed significant positive associations between outpatient mental health service utilization and both Powerful Others Locus of Control and Self-criticism.

CONCLUSIONS

These findings suggest that personality traits may play a role in treatment seeking behaviors for mental health problems over and above the presence of psychiatric disorders alone. The assessment of relevant personality constructs has the potential to inform and improve treatment outreach efforts.

The relationship of religiosity to older adults' mental health service use

This article uses data from the Naturally Occurring Retirement Community (NORC) Demonstration Project (N = 326) to examine older adults' utilization of mental health services. This study is guided by the behavioral model of health service utilization and helps to fill gaps in the literature by including religious affiliation, religiosity, and interaction terms as variables in regression models. These variables are important, as religion is more important in the lives of older adults than in the lives of their younger counterparts. This study found the rate of use of mental health services during the previous six months to be 19.0%, and those with higher levels of private religious activity and higher levels of intrinsic religiosity are more likely to have accessed some form of mental health service. However, frequency of attendance at religious services is not associated with the use or non-use of services. Information from this study suggests that more research is needed to specify the manner in which religious affiliation and religiosity work to affect the use of mental health services, and future studies must include religious variables in order for models of service use to be complete.

Disposition of emergency department patients with psychiatric comorbidity: results from the 2004 National Hospital Ambulatory Medical Care Survey

BACKGROUND

Few emergency department (ED) studies have examined how psychiatric comorbidity relates to hospitalisation decisions.

METHODS

We assessed the relationship of psychiatric comorbidity to hospitalisation decisions among ED patients in the 2004 National Hospital Ambulatory Medical Care Survey.

RESULTS

Patients with psychiatric comorbidity were five times more likely to be hospitalised than patients with a single psychiatric diagnosis. The most frequent psychiatric comorbidities involved substance use disorders (SUDs).

CONCLUSIONS

Psychiatric disorders are underdiagnosed among ED patients. We believe that this underdiagnosis may be partly responsible for the high hospitalisation rates of ED patients with SUDs.

Cognitive behavioral psychotherapy for generalized anxiety disorder: a primer

Generalized anxiety disorder is a highly debilitating psychologic disorder associated with cognitive, affective, behavioral and physiologic forms of rigidity and dysfunction. Chronic and uncontrollable worry, a future-oriented and highly negative form of verbal thought, is its hallmark symptom. Cognitive behavioral therapy, the most well-established psychologic treatment for generalized anxiety disorder, entails techniques designed to target and reduce dysfunction in each of these mutually interrelating domains. This review serves as an introduction to cognitive behavioral therapy for generalized anxiety disorder, including conceptualization, treatment methods and evidence for efficacy. Future directions for augmenting treatment efficacy are also discussed.

Explaining service use for mental health problems in the Dutch general population: the role of resources, emotional disorder and functional impairment

OBJECTIVE

To analyse explanations of service use in terms of resources, emotional (mood or anxiety) disorder and functional impairment.

METHOD

Data was derived from a prospective cohort study in a sample representative (n = 4848) of the Dutch adult general population.

RESULTS

The occurrence of an emotional (mood or anxiety) disorder led to a greater use of services as a partial consequence of the functional impairments that accompanied the disorder, but this applied only to primary care services and not to specialised mental health services. After adjustment for the influence of all other determinants in the model, people with more education and those with higher neuroticism scores were more likely to use specialised services in particular.

CONCLUSIONS

Future research could benefit from applying the models derived here to further clarify the use of the two service modalities, as well as to assess additional psychological resources.

Was there unmet mental health need after the September 11, 2001 terrorist attacks?

BACKGROUND

This study examined the use of professionals for mental health problems among New York City residents who were directly affected by the September 11, 2001 terrorist attacks on the World Trade Center (WTC) or had a probable diagnosis of post-traumatic stress disorder (PTSD) or depression in its aftermath. Correlates of help seeking from professionals for mental health problems after the attacks and barriers to care were also assessed.

METHOD

Data were from a random digit dial telephone survey of 2,752 adults representative of the Greater New York Metropolitan area conducted 6 months after the September 11 terrorist attacks.

RESULTS

Fifteen percent of those directly affected and 36% of those with probable PTSD or depression sought help from a professional for a mental health problem after the attacks. There was little new utilization of professionals for mental health problems after the attacks among persons who were not already receiving care prior to September 11. Barriers that prevented people from seeking help for mental health problems 6 months after the September 11 attacks included traditional barriers to care (e.g., cost) and barriers that are unique to the post-disaster context (e.g., the belief that others need the services more than oneself).

CONCLUSIONS

This study suggests that there was potential unmet mental health need in New York City 6 months after the September 11 attacks on the WTC, but these findings should be tempered by research showing an apparent decrease in population-rates of PTSD. In the aftermath of a disaster, interventions should target persons with mental health needs who were not previously seeking help from a professional for a mental health problem.

Idiopathic physical symptoms: a common manifestation of psychiatric disorders in primary care

Worldwide, patients with common mental disorders, such as depression and anxiety, have a tendency to present first to primary care exhibiting idiopathic physical symptoms. Typically, these symptoms consist of pain and other physical complaints that remain medically unexplained. While in the past, traditional psychopathology emphasized the relevance of somatic presentations for disorders, such as depression, in the last few decades, the "somatic component" has been neglected in the assessment and treatment of psychiatric patients. Medical specialties have come up with a variety of "fashionable" labels to characterize these patients and the new psychiatric nomenclatures, such as the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, attempt to classify these patients into a separate "somatoform disorders" category. These efforts fall short, and revisionists are asking altogether for the elimination of "somatoform disorders" from future nomenclatures. This review emphasizes the importance of idiopathic physical symptoms to the clinical phenomenology of many psychiatric disorders, offers suggestions to the diagnostic conundrum, and provides some hints for the proper assessment and management of patients with these common syndromes.

Prevalence and incidence studies of anxiety disorders: a systematic review of the literature

OBJECTIVE

To present the results of a systematic review of literature published between 1980 and 2004 reporting findings of the prevalence and incidence of anxiety disorders in the general population.

METHOD

A literature search of epidemiologic studies of anxiety disorders was conducted, using Medline and HealthSTAR databases, canvassing English-language publications. Eligible publications were restricted to studies that examined age ranges covering the adult population. A set of predetermined inclusion and exclusion criteria were used to identify relevant studies. Prevalence and incidence data were extracted and analyzed for heterogeneity.

RESULTS

A total of 41 prevalence and 5 incidence studies met eligibility criteria. We found heterogeneity across 1-year and lifetime prevalence rates of all anxiety disorder categories. Pooled 1-year and lifetime prevalence rates for total anxiety disorders were 10.6% and 16.6%. Pooled rates for individual disorders varied widely. Women had generally higher prevalence rates across all anxiety disorder categories, compared with men, but the magnitude of this difference varied.

CONCLUSION

The international prevalence of anxiety disorders varies greatly between published epidemiologic reports. The variability associated with all anxiety disorders is considerably smaller than the variability associated with individual disorders. Women report higher rates of anxiety disorders than men. Several factors were found to be associated with heterogeneity among rates, including diagnostic criteria, diagnostic instrument, sample size, country studied, and response rate.

High-end specificity of the children's depression inventory in a sample of anxiety-disordered youth

Using a receiver operating characteristic (ROC) analysis, the present study investigated the ability of the Children's Depression Inventory (CDI) to correctly detect depression in a sample of treatment-seeking anxious youth (N=44). The ADIS-C/P was used to determine diagnostic status of participants. Anxious children who met diagnostic criteria for a depressive disorder scored higher on the CDI than anxious children who did not meet criteria for a depressive disorder, supporting the CDI as a continuous measure of depressive symptomatology. In contrast, with regard to detecting a depressive disorder, CDI cut scores did not achieve favorable values across diagnostic utility indices (including the cut score of 13 that has been recommended). These findings support the CDI as a continuous measure of depressive symptoms, but do not support the CDI as a sole assessment for a diagnosis of depression within a sample of anxiety-disordered youth.

The cost of treating anxiety: the medical and demographic correlates that impact total medical costs

The purpose of this retrospective, multivariate analysis is to examine how medical conditions and demographic characteristics affect the costs of treating individuals diagnosed with anxiety. Data from MarketScan Databases [The MEDSTAT Group, 2000] were used to identify individuals with new episodes of anxiety. Multivariate analysis was used, with the dependent variable being the log of total medical costs. This analysis controlled for demographic characteristics, medical comorbidities, anxiety diagnosis, and prior resource utilization. A smearing estimate is used to calculate the total medical costs for patients with any anxiety disorder. The mean estimated total medical cost for individuals diagnosed with any anxiety disorder was $6,475. The multivariate model indicates that controlling for demographics and other disease states, generalized anxiety disorder (GAD), panic disorders, and posttraumatic stress disorder (PTSD) are associated with a $2,138, $1,603, and $3,940 increase, respectively, in the total medical cost (P < .0001). The incremental impact of depression, other anxiety disorders, and prior mental health diagnoses on the total medical costs were $1,945, $1,900, and $1,515, respectively (P < .0001). Individuals with the highest costs, and therefore the greatest need for intervention, are anxious patients with depression, individuals diagnosed with PTSD or GAD, and individuals diagnosed with both anxiety and a comorbid medical condition such as an acute myocardial infarction or diabetes.

Use of mental health services in a developing country. Results from the Nigerian survey of mental health and well-being

BACKGROUND

Evidence from developed industrialized countries suggests poor uptake of mental health services. No data exist in developing resource-constrained countries about met and unmet need for mental health service in the community.

METHOD

A four-stage stratified probability sample of households was studied in the Yoruba-speaking part of Nigeria (population, approximately 25 million people or 22% of the Nigerian national population). Face-to-face interviews were conducted with persons 18 years old and above (n=4,984) using the World Mental Health version of the Composite International Diagnostic Interview. We determined the proportions of respondents with 12-month Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) anxiety, mood, or substance use disorder who had received any mental health treatment and the correlates of treatment receipt.

RESULTS

Only 9.0% of those with any 12-month DSM-IV disorder had received treatment. While 11% of those with a mood disorder had received some treatment, none of those with substance use disorders had used a mental health service. Most treatments were received from general medical settings, with only about 1% of those with DSM-IV disorders receiving specialist mental health service. Surprisingly, complementary or alternative health providers were also consulted by only about 4% of those with mental disorders, although a much higher proportion of 57% of those with no DSM-IV disorders but who nevertheless received mental health treatment did so from such providers. Irrespective of the disorders or the sector where treatment was received, virtually no treatment was adjudged minimally adequate.

CONCLUSION

There is a striking level of unmet need for mental health service in the community in this developing country setting. While inadequacy of the formal public health sector may be partly responsible for this observation, there is the likelihood that receipt of treatment for mental health problems may also be hampered by the public's poor knowledge of the nature of the disorders and by stigma.

Challenges in the treatment of anxiety disorders: beyond guidelines

Anxiety disorders are highly prevalent, come in many forms and are often chronic, with many patients requiring long-term maintenance therapy. Anxiety and depression may also be comorbid in up to 50% of patients, leading to problems during diagnosis and treatment. Despite their frequency, the recognition and treatment of anxiety disorders is frequently suboptimal, with as few as 15% of patients obtaining treatment consistent with evidence-based care recommendations. Current treatment guidelines for anxiety disorders include a range of pharmacological and non-pharmacological approaches. However, the use of these guidelines alone may not be sufficient to improve patient outcomes. Optimal treatments for anxiety should be based on chronic disease management and balance efficacy with long-term tolerability. Current first-line therapies should include broad-spectrum agents that have proven efficacy in treating both anxiety and depression and are effective across all treatment phases. The allosteric serotonin reuptake inhibitor (ASRI), escitalopram, is a particularly effective treatment, offering high rates of remission combined with relatively low rates of discontinuation due to adverse events. Combination therapy involving medication and psychological approaches, e.g., cognitive behavioral therapy, may also be helpful. Novel approaches to delivering psychotherapy and self-management via the Internet may address accessibility issues for evidence-based psychological treatments.

Recovery from depression: a two-year follow-up study of general population subjects

BACKGROUND

The recovery from depression and factors associated with it are not well known in the general population.

AIMS

To conduct a two-year follow-up of general population subjects and investigate their recovery from depression.

METHODS

Individuals who were assessed as suffering from depression on the basis of Beck Depression Inventory (BDI) scores were monitored for two years.

RESULTS

Sixty-five per cent were still depressed after two years of follow-up. Negative life events had occurred more often in those who had remained depressed than in the others. Logistic regression analysis revealed that a high initial BDI score and a worsening of a subject's economic situation during the follow-up period were associated with failure to recover. Lack of use of health services was associated with non-recovery.

CONCLUSION

Depression may be more chronic in the general population than previously has been thought.

Clinical differences among patients treated for mental health problems in general medical and specialty mental health settings in the National Comorbidity Survey Replication

OBJECTIVE

General medical (GM) treatments for mental health disorders are less likely than specialty mental health (SMH) treatments to be adequate. We explored whether differences in the clinical characteristics of patients treated in each sector (GM-only or SMH-only) or in both sectors (GM+SMH) may help to explain this finding.

METHOD

We analyzed data from the National Comorbidity Survey Replication (NCS-R), a nationally representative household survey of 5692 English-speaking adult household residents that was carried out in 2001-2003. The NCS-R used a fully structured diagnostic interview to assess DSM-IV disorders, including mood, anxiety, impulse control and substance use disorders. We classified disorders in terms of a three-category severity gradient (serious, moderate and mild) based on information about clinically significant distress and role impairment. We collected self-report data on chronic physical conditions, sociodemographics and type of treatment received for emotional and substance use problems in the 12 months before the interview.

RESULTS

Patients who received GM+SMH treatment had more severe mental disorders and a higher prevalence of mood and anxiety disorders than patients who received treatment in only one of the two sectors. Patients seen in the GM-only and GM+SMH sectors had more chronic physical conditions than patients seen in the SMH-only sector.

CONCLUSION

Patient characteristics may partially explain the lower intensity and adequacy of GM treatment.

Major depression and allergy: does neuroticism explain the relationship?

OBJECTIVE

To determine the association between major depression, neuroticism, and self-reported allergy among adults in the community.

METHODS

Data were drawn from the Midlife Development in the United States Survey, a nationally representative sample of 3,032 adults age 25 to 74. ANOVA and multiple logistic regression analyses were used to determine the association between depression and allergy and the role of neuroticism in these relationships. These links were also examined by gender.

RESULTS

Among adults in the community, major depression was associated with a significantly increased likelihood of allergy (odds ratio [OR], 1.5; 95% confidence interval [CI], 1.14-1.98). Higher levels of neuroticism were also significantly associated with increased likelihood of allergy (OR, 1.22; 95% CI, 1.04-1.43). Among women, major depression was associated with a significantly increased likelihood of allergy (OR, 1.67; 95% CI, 1.15-2.41), and this relationship persisted after adjusting for demographic characteristics and neuroticism. Among men, there was no significant relationship between allergy and depression, yet neuroticism was related to allergy (OR, 1.42; 95% CI, 1.42-1.82), which persisted after adjustment for depression.

CONCLUSION

These data are consistent with results of previous studies showing an association between major depression and allergy among adults and extend these data by providing preliminary evidence suggesting that this association is specific to women and independent of the effects of neuroticism among women. In addition, the data provide preliminary evidence that neuroticism may be related to allergy among men, though no link between depression and allergy was found among men. Future research with prospective, longitudinal studies is needed next to understand the possible biological underpinnings of these associations.

The mood spectrum: improving the diagnosis of bipolar disorder

Although the distinction between bipolar and unipolar disorders served our field well in the early days of psychopharmacology, in clinical practice it is apparent that their phenotypes are only partially described by current diagnostic classification systems. A substantial body of evidence has accrued suggesting that clinical variability needs to be viewed in terms of a broad conceptualization of mood disorders and their common threshold or subthreshold comorbidity. The spectrum model provides a useful dimensional approach to psychopathology and is based on the assumption that early-onset and enduring symptoms shape the adult personality and establish a vulnerability to the subsequent development of Axis-I disorders. To obtain a clearer understanding of the depressive phenotype, it is pivotal that we increase our detection of hypomanic symptoms so that clinicians can better distinguish bipolar II disorder from unipolar depression. Diagnostic criteria sensitive to hypomanic symptoms have been identified that suggest bipolar II disorder is at least as prevalent as major depression. Moreover, the comorbidities of these illnesses are very different and alcoholism in particular appears to be a greater problem in bipolar II disorder than in unipolar depression. Structured clinical interviews and patient self-report questionnaires have also successfully identified the presence of hypomanic symptoms in patients with unipolar disorder and support the concept of a spectrum of bipolar illness. In conclusion, the importance of subthreshold syndromes should not be underestimated as failure to recognize bipolar spectrum disorder could delay treatment and worsen prognosis.

Generalised anxiety disorder in Singapore: prevalence, co-morbidity and risk factors in a multi-ethnic population

BACKGROUND

There has been a relative lack of epidemiological data on generalised anxiety disorder (GAD) in Southeast Asia. A previous study reported a lifetime prevalence of 1.5% and highlighted low preference for seeking professional help and consultation by persons suspected to be suffering from mental health problems. The present study is part of a National Mental Health survey of adults conducted from February 2003-March 2004 specifically assessing anxiety and depression in Singapore. In this paper we report on prevalence, co-morbidity and risk factors associated with GAD.

METHODS

We interviewed 2,847 households from an ethnically stratified random sample of adults aged 20-59 years who were Singapore citizens or permanent residents. The General Health Questionnaire and Schedule for Clinical Assessment of Neuropsychiatry were administered, which generated Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) diagnoses of GAD. We assessed socio-demographic correlates, life events, medical and other psychiatric co-morbidities related to GAD.

RESULTS

Lifetime prevalence of GAD was 3.3%, current prevalence is 3.0%. Female to male ratio is 3.6:1. GAD was significantly associated (p<0.001) with the presence of other psychiatric co-morbidities, including major depressive disorder, dysthymia, panic disorder, agoraphobia and social phobia. Prevalence increased in older individuals, with the odds of association greatest in subjects with three or more co-morbid medical conditions [adjusted odds ratio (OR) 3.66]. Those who had experienced one or more threatening life events showed increased odds of association with GAD. Chinese ethnicity, the divorced and persons from both the upper and the lowest socio-economic status had highest odds of association with GAD.

CONCLUSIONS

We challenge established notions that GAD tends to be a disorder of the socially disadvantaged. Life events are important as precipitating factors in GAD, and uniquely different types of events appear to affect both extremes of social classes. High co-morbidity associations with current GAD are grounds for concern. This may suggest failure to seek treatment, hence giving rise to an increase in severity of the primary condition.

Inequities in mental health care after health care system reform in Chile

OBJECTIVES

We compared differences in mental health needs and provision of mental health services among residents of Santiago, Chile, with private and public health insurance coverage.

METHODS

We conducted a cross-sectional survey of a random sample of adults. Presence of mental disorders and use of health care services were assessed via structured interviews. Individuals were classified as having public, private, or no health insurance coverage.

RESULTS

Among individuals with mental disorders, only 20% (95% confidence interval [CI]=16%, 24%) had consulted a professional about these problems. A clear mismatch was found between need and provision of services. Participants with public insurance coverage exhibited the highest prevalence of mental disorders but the lowest rates of consultation; participants with private coverage exhibited exactly the opposite pattern. After adjustment for age, income, and severity of symptoms, private insurance coverage (odds ratio [OR]=2.72; 95% CI=1.6, 4.6) and higher disability level (OR=1.27, 95% CI=1.1, 1.5) were the only factors associated with increased frequency of mental health consultation.

CONCLUSIONS

The health reforms that have encouraged the growth of the private health sector in Chile also have increased risk segmentation within the health system, accentuating inequalities in health care provision.
