Mental disorders and disability among patients in a primary care group practice.

OBJECTIVE: This article examines social and occupational disability associated with several DSM-IV mental disorders in a group of adult primary care outpatients. METHOD: The subjects were 1,001 primary care patients (aged 18-70 years) in a large health maintenance organization. Data on each patient's sociodemographic characteristics and functional disability, including scores on the Sheehan Disability Scale, were collected at the time of a medical visit. A structured diagnostic interview for current DSM-IV disorders was then completed by a mental health professional over the telephone within 4 days of the visit. RESULTS: The most prevalent disorders were phobias (7.7%), major depressive disorder (7.3%), alcohol use disorders (5.2%), generalized anxiety disorder (3.7%), and panic disorder (3.0%). A total of 8.3% of the patients met the criteria for more than one mental disorder. The proportion of patients with co-occurring mental disorders varied by index disorder from 50.0% (alcohol use disorder) to 89.2% (generalized anxiety disorder). Compared with patients who had a single mental disorder, patients with co-occurring disorders reported significantly more disability in social and occupational functioning. After adjustment for other mental disorders and demographic and general health factors, compared with patients with no mental disorder, only patients with major depressive disorder, bipolar disorder, phobias, and substance use disorders had significantly increased disability, as measured by the Sheehan Disability Scale. CONCLUSIONS: Primary care patients with more than one mental disorder are common and highly disabled. Individual mental disorders have distinct patterns of psychiatric comorbidity and disability.

Vulnerability of Jews to affective disorders.

OBJECTIVE: Psychiatric literature over the past 100 years suggests that Jews are at higher risk for affective disorders than numbers of other religious groups. To examine these claims, the authors analyzed data from the National Institute of Mental Health Epidemiologic Catchment Area (ECA) study. In addition, the relationships among gender, alcoholism, and major depression were investigated. METHOD: The period prevalence and lifetime rates of DSM-III major depression among Jews, Catholics, Protestants, individuals in other religious groups, and individuals with no religious affiliation were examined in the Los Angeles and New Haven, Conn., ECA data. Logistic regression with covariates for site, gender, marital status, and socioeconomic status was used to estimate odds ratios and 95% confidence intervals. The calculated rates, based on the combined data from ECA study waves 1 and 2 for the white population, were weighted according to the 1980 U.S. population census. Female-to-male rate ratios and rates of alcohol abuse/dependence were also obtained. RESULTS: While no differences were found among females, Jewish males had significantly higher rates of major depression than Catholics, Protestants, and all non-Jews combined. Jews had a 1:1 female-to-male ratio for major depression, in contrast to the other religious groups, which approached the universal 2:1 ratio. Rates of alcohol abuse/dependence were inversely related to rates of major depression. CONCLUSIONS: The results support only in part the earlier reports that Jews have higher rates of depression. The equal gender distribution of major depression among Jews may be associated with the lower rate of alcoholism among Jewish males.

Interpersonal psychotherapy: current status.

Interpersonal psychotherapy (IPT), a time-limited treatment for major depression, was developed, defined in a manual, and tested in randomized clinical trials by the late Gerald L Klerman, MD, and collaborators. It has subsequently been modified for different age groups (adolescents-elderly), types of mood disorders (dysthymia, bipolar disorder, antepartum and postpartum patients), and non-mood disorders (bulimia, drug abuse, borderline personality disorder, social phobia, somatization, medically ill patients). It has been used as a long-term treatment, in a group format, over the telephone, and as a patient guide. It has been translated into Italian, German and recently Japanese. Having begun as a research intervention, IPT is only recently being disseminated among clinicians or in residency training programs. The publication of efficacy data, the appearance of two practice guidelines in the United States that include IPT among treatments for depression, the interest in defined treatments for managed care and the endorsement of Consumers Guide have led to increasing requests for information and training. This paper briefly describes the concepts and techniques of IPT and the current status of adaptation. In summary, evidence from controlled clinical trials suggests that IPT is a reasonable alternative or adjunct to medication as an acute, continuation, and/or maintenance treatment for patients with major or mild depression, patients who are human immunodeficiency virus (HIV) positive, or who have bulimia. It is a promising treatment for depressed adolescents and for geriatric patients, for patients with dysthymia and as treatment for depressed couples marital disputes. A final conclusion awaits the completion of clinical trials underway before substantial claims can be made. IPT is not effective, as compared to a standard drug program, for opiate and cocaine addicted patients.

Unipolar relatives in bipolar pedigrees: a search for elusive indicators of underlying bipolarity.

In an effort to identify features indicative of underlying bipolarity within the unipolar relatives of bipolar probands, we compared unipolar relatives of bipolars with unipolar relatives of controls. Using data from the Yale-NIMH Collaborative Study of Depression, we compared a number of demographic and clinical features individually, and then developed a logistic regression model for the differences found. Unipolar relatives of bipolars were generally similar to relatives of controls, but they were older and more likely to suffer from more severe, even psychotic, depression, and somewhat less likely to report a brief transition into their illness. A multiple logistic regression model for observed differences was highly statistically significant, but had limited ability to discriminate effectively between the two groups. These findings suggest that more stringent diagnostic criteria might be beneficial if unipolar relatives are counted as affected in linkage studies of bipolar disorder. The ability of this strategy to improve the "clinical phenotype" is limited, however, and other approaches may be needed to identify features of underlying bipolarity and thus to define "caseness" for unipolar relatives in linkage analyses of bipolar disorder.

Subthreshold psychiatric symptoms in a primary care group practice.

BACKGROUND: The authors define 6 groups of subthreshold psychiatric symptoms that do not meet the full criteria for a DSM-IV Axis I disorder and examine the clinical significance of these symptoms in an outpatient primary care sample. METHODS: The subjects were 1001 adult primary care patients in a large health maintenance organization. Data on sociodemographic characteristics and functional impairment, including scores on the Sheehan Disability Scale, were collected at the time of the medical visit, and a structured diagnostic interview for DSM-IV disorders was completed by telephone within 4 days of the visit. Subthreshold symptoms were defined for depressive, anxiety, panic, obsessive-compulsive, drug, and alcohol symptoms. RESULTS: Subthreshold symptoms were as or more common than their respective Axis I disorders: panic (10.5% vs 4.8%), depression (9.1% vs 7.3%), anxiety (6.6% vs 3.7%), obsessive-compulsive (5.8% vs 1.4%), and alcohol (5.3% vs 5.2%) and other drug (3.7% vs 2.4%) cases. Patients with each of the subthreshold symptoms had significantly higher Sheehan Disability Scale scores (greater impairment) than did patients with no psychiatric symptoms. Many patients (22.6%-53.4%) with subthreshold symptoms also met the full criteria for other Axis I disorders. After adjusting for the confounding effects of other Axis I disorders, other subthreshold symptoms, age, sex, race, marital status, and perceived physical health status, only depressive symptoms, major depressive disorder, and, to a lesser extent, panic symptoms were significantly correlated with the impairment measures. CONCLUSIONS: In these primary care patients, the morbidity of subthreshold symptoms was often explained by confounding mental, physical, or demographic factors. However, depressive symptoms and, to a lesser extent, panic symptoms were disabling even after controlling for these factors. Primary care clinicians who detect subthreshold psychiatric symptoms should consider a broad psychiatric assessment.

Comparison of RDC, DSM-III, DSM-III-R diagnostic criteria for generalized anxiety disorder.

The diagnosis of generalized anxiety disorder (GAD) has been controversial since its inception. It remains unclear whether more stringent diagnostic criteria, such as in DSM-III-R, have improved the validity of GAD. Family studies suggest that GAD aggregates at least weakly in families of probands with GAD, and support the separation of panic disorder (PD) and GAD. Therefore, we can use a family study design to examine the validity of GAD. Independent familial transmission of GAD supports the validity of GAD. We report here the risk of GAD according to RDC, DSM-III, and DSM-III-R criteria in the first-degree relatives of probands from four diagnostic groups: panic disorder, panic disorder with major depression, early-onset major depression (MDD), and normal controls. We did not find an elevated risk of DSM-III or DSM-III-R GAD in the relatives of any of the ill proband groups compared to the relatives of the never mentally ill when controlling for proband comorbidity for GAD. In contrast, RDC GAD aggregates in the first-degree relatives of probands from both of the PD proband groups (with and without MDD) compared to relatives of the normal control group. The inclusion of cases of subsyndromal panic attacks that did not meet the strict RDC for panic disorder as meeting the less restrictive RDC for GAD may partially account for the familial aggregation of RDC panic disorder and RDC GAD. RDC GAD seems to identify one or more syndrome(s) that may be on the familial spectrum of panic disorder. This syndrome may represent a mild or early variant of panic disorder. We also found a trend for RDC and DSM-III GAD to aggregate in the first-degree relatives of the MDD proband group compared to the relatives of the never mentally ill controls. These data suggest that GAD demonstrates more independent familial transmission from PD and MDD when defined by DSM-III-R criteria than when defined by RDC or DSM-III, and thus support the validity of DSM-III-R GAD.

Suicidal ideation in primary care.

OBJECTIVE: To describe the prevalence and clinical characteristics of primary care patients who report suicidal ideation during the month before their medical visit. DESIGN: Analysis of a self-administered suicidal ideation screening item using sociodemographic data, treatment history, and clinical data from structured interviews. SETTING: Three Rhode Island private family practices, a South Carolina family medicine residency, and a California prepaid internal medicine group practice. PATIENTS: Adult primary care patients (N = 2,749), 18 to 70 years old, who are able to read and write English, able to complete study forms, and willing to provide informed consent. RESULTS: Sixty-seven (2.44%) of the patients reported suicidal ideation ("feeling suicidal") during the past month, and most of those patients (58.2%) received no mental health care during that time. The adjusted risk of suicidal ideation was significantly elevated for patients with self-reported fair or poor physical health (odds ratio [OR] 2.5; 95% confidence interval [CI] 1.5, 4.1), fair to poor emotional health (OR 18.0; 95% CI 8.8, 37.0), marital distress (OR 4.4; 95% CI 2.2, 8.8), and recent mental health-related work loss (OR 6.3; 95% CI 3.7, 10.5). In the California sample, patients with major depression (R 31.2; 95% CI 12.8, 76.1). generalized anxiety disorder (OR 23.4; 95% CI 8.1, 67.1), and drug abuse or dependence (OR 9.6; 95% CI 2.9, 31.6) were at increased risk of suicidal ideation. The "feeling suicidal" item identified 10 of 12 patients who acknowledged a recent plan to kill themselves. CONCLUSIONS: In these primary care patients, suicidal ideation is strongly associated with mental disorder and mental health-related functional impairment, and can be detected with a single self-report "feeling suicidal" item.

Brief screens for mental disorders in primary care.

We evaluated a set of diagnostic screens for mental disorders in primary care. A self-administered screening questionnaire containing 26 items testing for multiple mental disorders was completed by 1,001 patients. Brief diagnostic modules, structured for psychiatric diagnoses, were subsequently administered to each patient by a research nurse. Operating characteristics of the screens were as follows: alcohol dependence (sensitivity [SE] 0.75; positive predictive value [PPV] 0.58; [kappa] 0.63), drug dependence (SE 0.50; PPV 0.50; kappa 0.50), generalized anxiety disorder (SE 0.74; PPV 0.44; kappa 0.44), major depressive disorder (SE 0.71; PPV 0.52; kappa 0.50), obsessive compulsive disorder (SE 0.71; PPV 0.15; kappa 0.21), and panic disorder (SE 0.71; PPV 0.43; kappa 0.48). Other chance-corrected measures of agreement are also reported, and criterion validity of the screens is examined. The results provide evidence that the screens discriminate between patients with symptomatology meeting established diagnostic criteria and those without. They detected previously unrecognized cases in this study and may prove to be valuable tools for psychiatric diagnosis in primary care.

The role of drug and alcohol abuse in recent increases in depression in the US.

Previous studies have reported an increase in depression among recent birth cohorts. Concurrent with the increase in rates of depression, there have been increases in rates of drug and alcohol abuse and dependence. This study sought to determine if the recent increase in rates of depression could be attributed to co-morbid alcohol and drug abuse. The data derived from two studies: (1) a sample of relatives of probands with affective disorder; and (2) a community survey of the US population. The piecewise exponential statistical model was applied to evaluate the association of gender, age, period and birth cohort with rates of major depressive disorder (MDD) separately for those with, and without, diagnoses of alcohol or drug abuse. Elevated rates of MDD occurred among those with co-morbid drug and alcohol abuse in both the family and community samples. However, there were also temporal increases in rates of MDD in those with no such co-morbidity. Specifically there were effects of age and gender for both studies; in addition, there was a period effect in the family study and a birth cohort effect in the community sample. The recent increases in depression in the US cannot be accounted for solely by concurrent increases in co-morbid drug and alcohol abuse. Temporal (period and cohort) effects on rates of depression occur in addition to the contribution of co-morbid drug and alcohol abuse or dependence.

The NIMH Methods for the Epidemiology of Child and Adolescent Mental Disorders (MECA) Study: background and methodology.

OBJECTIVE: A collaborative study was conducted to develop methods for surveys of mental disorder and service utilization in unscreened population-based samples of children and adolescents. METHOD: Probability household samples of youths 9 through 17 years of age were selected at four sites and interviews were conducted with a total of 1,285 pairs of youths and their adult caretakers in their homes. Lay interviewers administered a computer-assisted version of the NIMH Diagnostic Interview Schedule for Children Version 2.3 and structured interviews to assess demographic variables, functional impairment, risk factors, service utilization, and barriers to service utilization. RESULTS: More than 7,500 households were enumerated at four sites, with enumeration response rates above 99%. Across sites, 84% of eligible youth-caretaker pairs were interviewed for about 2 hours each. Ninety-five percent of both youths and caretakers found the interview to be acceptable enough to recommend to a friend. CONCLUSIONS: These findings indicate that large-scale epidemiological surveys of mental disorders and mental health service use involving lengthy interviews in the homes of unscreened population-based samples of youths and their adult caretakers are acceptable to the community and can achieve good response rates. The other reports in this Special Section address the reliability and validity of the various survey instruments and other key findings.

The cross-national epidemiology of social phobia: a preliminary report.

We present a preliminary report on cross-national rates, age at onset, comorbidity, suicide attempts and symptom profiles of social phobia. These data are based on epidemiologic community surveys using similar methods from the United States, Canada, Puerto Rico and Korea. The lifetime rate of social phobia (cases per 100 persons) varies by country, from 2.6 in the United States to 0.5 in Korea. Rates are higher in females than in males in all countries. The age of onset for any phobia is mid-teens to early twenties, and social phobia usually has its first onset before other psychiatric disorders. Only a third or fewer cases of social phobia are uncomplicated by another psychiatric disorder. The presence of social phobia increases the risk of suicide attempts in persons with any other psychiatric disorder. Symptom profiles vary by country. Our data indicate consistent patterns but different cultural expressions of social phobia in the countries studied. The early age of onset of social phobia followed subsequently by another psychiatric disorder raises the possibility that early treatment of social phobia could prevent the onset of other psychiatric disorders.

Psychotic symptoms in primary care.

BACKGROUND: Psychotic symptoms include a variety of disturbances in perception, reality testing, speech, and behavior. We examine the prevalence, distribution, treatment, and functional impairment associated with psychotic symptoms in primary care patients. METHODS: Data are drawn from a recent study of adult primary care patients (N = 1001) in a large, urban, prepaid group practice. At the medical visit, patients completed a questionnaire that probed demographic characteristics, health status, and mental health care utilization. Following the visit, patients received a telephone-administered, structured psychiatric interview that included 11 psychotic symptoms. Medication prescription data were also available. Comparisons are presented of patients with and without psychotic symptoms. RESULTS: Thirty-seven (3.7%) patients reported one or more psychotic symptoms, most commonly a belief that others were spying on or following them (n = 16). As compared with patients without psychotic symptoms, a larger proportion of the patients with psychotic symptoms reported mental health-related work loss (54.1% vs 17.9%, P < .0001), suicidal ideation (21.6% vs 2.6%, P < .0001), major depressive disorder (32.4% vs 6.3%, P < .0001), bipolar disorder (29.7% vs 1.2%, P < .0001), and several other mental disorders. An antipsychotic medication had been prescribed during the previous 17 to 20 months for only two (5.4%) of the patients with psychotic symptoms. CONCLUSIONS: Psychotic symptoms were relatively common (3.7%) in this practice and were strongly associated with functional impairment and affective, anxiety, or substance use disorders. Primary care physicians are encouraged to examine patients with these mental disorders for the presence of psychotic symptoms.

Evaluation of screens for mental disorders in primary care: methodological issues.

Several brief screens are available to help identify mental disorders in primary care. In choosing among them, an investigator must consider the clinical research setting, the sampling framework, and the strategy used to assess the reliability and validity of the instruments. These issues are considered in the context of the study that revised the Symptom-Driven Diagnostic System for Primary Care (SDDS-PC) for the DSM-IV. The sample size determination strategy used in that study rendered a sample that was large enough to allow for a split-sample approach to data analysis. The screen algorithms were developed on an index sample, and the operating characteristics were cross-validated with data from a separate sample. Standard operating characteristics as well as chance-corrected, or quality operating characteristics were used to evaluate the construct validity of the screens. Criterion-related validity of the screens was evaluated by examining functional impairment. Screens such as these may be valuable clinical and research tools for psychiatric diagnosis in primary care.

Depression in women: implications for health care research.

Epidemiologic data from around the world demonstrate that major depression is approximately twice as common in women than men and that its first onset peaks during the childbearing years. Progress has been made in understanding the epidemiology of depression and in developing effective treatments. Much remains to be learned about the basic pathogenesis of depression and the specific treatment needs of depressed women and their offspring, especially during the reproductive years.

Family psychiatric screening instruments for epidemiologic studies: pilot testing and validation.

Family history, a risk factor for psychiatric disorders, is infrequently assessed in epidemiologic studies due to time and cost constraints. We designed a brief computer-scorable instrument, the Family History Screen for Epidemiologic Studies (FHE), which collects a pedigree and screens for 15 DSM-III diagnoses in an informant and in his family members. The FHE was administered to one informant in 77 families in which we had collected pedigrees, interviewed 77 informants and 239 relatives using the Lifetime Anxiety version of the schedule for Affective Disorders and Schizophrenia or the Epidemiologic version of the Schedule for Affective Disorders and Schizophrenia for School-Aged Children, and performed best-estimate diagnoses. We evaluated the accuracy with which the FHE predicted best-estimate diagnoses. For adults reporting on themselves, the FHE demonstrated high levels of sensitivity and specificity for depression (67.4, 75.0) and panic (92.5, 89.2), and low sensitivity and high specificity for substance abuse (33.3, 93.6). For informants reporting on adult relatives, sensitivity was low and specificity was high for depression (35.2, 84.9), panic (20.0, 91.7), and substance abuse (42.1, 93.4). For informants reporting on children, perhaps due to lower prevalence, sensitivity and specificity were poor. The FHE is a good screen for psychiatric disorders in adult informants, but it is not useful for family history. It may be useful in primary care medical settings as a screen for psychiatric history.
