Health-related quality of life in primary care patients with mental disorders. Results from the PRIME-MD 1000 Study.

OBJECTIVE: To determine if different mental disorders commonly seen in primary care are uniquely associated with distinctive patterns of impairment in the components of health-related quality of life (HRQL) and how this compares with the impairment seen in common medical disorders. DESIGN: Survey. SETTING: Four primary care clinics. SUBJECTS: A total of 1000 adult patients (369 selected by convenience and 631 selected by site-specific methods to avoid sampling bias) assessed by 31 primary care physicians using PRIME-MD (Primary Care Evaluation of Mental Disorders) to make diagnoses of mood, anxiety, alcohol, somatoform, and eating disorders. MAIN OUTCOME MEASURES: The six scales of the Short-Form General Health Survey and self-reported disability days, adjusting for demographic variables as well as psychiatric and medical comorbidity. RESULTS: Mood, anxiety, somatoform, and eating disorders were associated with substantial impairment in HRQL. Impairment was also present in patients who only had subthreshold mental disorder diagnoses, such as minor depression and anxiety disorder not otherwise specified. Mental disorders, particularly mood disorders, accounted for considerably more of the impairment on all domains of HRQL than did common medical disorders. Finally, we found marked differences in the pattern of impairment among different groups of mental disorders just as others have reported unique patterns associated with different medical disorders. Whereas mood disorders had a pervasive effect on all domains of HRQL, anxiety, somatoform, and eating disorders affected only selected domains. CONCLUSIONS: Mental disorders commonly seen in primary care are not only associated with more impairment in HRQL than common medical disorders, but also have distinct patterns of impairment. Primary care directed at improving HRQL needs to focus on the recognition and treatment of common mental disorders. Outcomes studies of mental disorders in both primary care and psychiatric settings should include multidimensional measures of HRQL.

Gender differences in depression in primary care.

OBJECTIVES: To determine gender differences in the frequency and manifestation of depression in primary care. STUDY DESIGN: PRIME-MD, a new assessment tool, was tested in 1000 patients as an aid to diagnose depression in primary care patients. Answers to a self-assessment questionnaire completed by patients determined whether physicians administered the mood module in the Clinician Evaluation Guide to diagnose depression. Functional status was assessed with the Medical Outcomes Study Short Form (SF-20). RESULTS: More women than men were diagnosed as having a mood disorder (31% vs 19%; p < 0.01), and an antidepressant was newly prescribed only for women (p < 0.001). There were no gender differences in physician ratings of patients' health, but women rated their health significantly more poorly than did men. Similarly, functional impairment scores were significantly lower in women than in men. CONCLUSIONS: Women are much more likely than men to have depressive disorders, and when these disorders are diagnosed, to receive a prescription for antidepressant medication. Further research is needed to determine why women seem to suffer disproportionately from symptoms of depression and signs of functional impairment.

Psychiatric comorbidity, health status, and functional impairment associated with alcohol abuse and dependence in primary care patients: findings of the PRIME MD-1000 study.

The psychiatric comorbidity, health, and functioning of primary care patients with alcohol abuse and dependence (AAD) were investigated in a sample of 1,000 patients. Psychiatric symptomatology was assessed with the Primary Care Evaluation of Mental Disorders (PRIME-MD) diagnostic system. Health and functional status was assessed with the Medical Outcomes Study Short Form General Health Survey (SF-20). Results indicated that use of the PRIME-MD system brought about a 71% increase in physician recognition of AAD. AAD patients were diagnosed with substantial psychiatric comorbidity, and they reported poorer health and functioning than did patients without any psychiatric disorders. However, they reported less impairment and psychiatric comorbidity than did patients with other psychiatric disorders. Results also indicated that AAD patients' health and functioning were associated with the presence or absence of psychiatric comorbidity.

Binge eating disorder in a community-based sample of successful and unsuccessful dieters.

This study examined binge eating and weight cycling in a community-based sample of successful (46 women, 44 men) and unsuccessful (29 women, 25 men) dieters. Successful dieters had lost at least 15% of body weight, kept the weight off for at least 1 year, and regained no more than 10 lb (average weight loss = 48 lb). Subjects completed a written questionnaire and were interviewed by phone several weeks later. Unsuccessful dieters were more obese when starting on a diet (average body mass index = 35.6 compared to 32.1) and were much more likely to have lost and regained 20 lb. Six-month prevalence of binge eating disorder (BED) was 19% for unsuccessful dieters and 6% for successful dieters; lifetime prevalence was 15% and 13%, respectively. Unsuccessful dieters were two to three times more likely to perceive a lack of control during an episode of overeating, to be disgusted with themselves for overeating, and to eat alone because they were embarrassed. Encouraging dieters to set realistic goals, identify potential relapse situations, and interpret lapses may help them succeed.

Utility of a new procedure for diagnosing mental disorders in primary care. The PRIME-MD 1000 study.

OBJECTIVE: To assess the validity and utility of PRIME-MD (Primary Care Evaluation of Mental Disorders), a new rapid procedure for diagnosing mental disorders by primary care physicians. DESIGN: Survey; criterion standard. SETTING: Four primary care clinics. SUBJECTS: A total of 1000 adult patients (369 selected by convenience and 631 selected by site-specific methods to avoid sampling bias) assessed by 31 primary care physicians. MAIN OUTCOME MEASURES: PRIME-MD diagnoses, independent diagnoses made by mental health professionals, functional status measures (Short-Form General Health Survey), disability days, health care utilization, and treatment/referral decisions. RESULTS: Twenty-six percent of the patients had a PRIME-MD diagnosis that met full criteria for a specific disorder according to the Diagnostic and Statistical Manual of Mental Disorders, Revised Third Edition. The average time required of the primary care physician to complete the PRIME-MD evaluation was 8.4 minutes. There was good agreement between PRIME-MD diagnoses and those of independent mental health professionals (for the diagnosis of any PRIME-MD disorder, kappa = 0.71; overall accuracy rate = 88%). Patients with PRIME-MD diagnoses had lower functioning, more disability days, and higher rates of health care utilization than did patients without PRIME-MD diagnoses (for all measures, P < .005). Nearly half (48%) of 287 patients with a PRIME-MD diagnosis who were somewhat or fairly well-known to their physicians had not been recognized to have that diagnosis before the PRIME-MD evaluation. A new treatment or referral was initiated for 62% of the 125 patients with a PRIME-MD diagnosis who were not already being treated. CONCLUSION: PRIME-MD appears to be a useful tool for identifying mental disorders in primary care practice and research.

Physical symptoms in primary care. Predictors of psychiatric disorders and functional impairment.

OBJECTIVE: To examine how the type and number of physical symptoms reported by primary care patients are related to psychiatric disorders and functional impairment. DESIGN: Outpatient mental health survey. SETTING: Four primary care clinics. PATIENTS: One thousand adult clinic patients, of whom 631 were selected randomly or consecutively and 369 by convenience. MAIN OUTCOME MEASURES: Psychiatric disorders as determined by the Primary Care Evaluation of Mental Disorders procedure; the presence or absence of 15 common physical symptoms and whether symptoms were somatoform (ie, lacked an adequate physical explanation); and functional status as determined by the Medical Outcomes Study Short-form General Health Survey. RESULTS: Each of the 15 common symptoms was frequently somatoform (range, 16% to 33%). The presence of any physical symptom increased the likelihood of a diagnosis of a mood or anxiety disorder by at least twofold to three-fold, and somatoform symptoms had a particularly strong association with psychiatric disorders. The likelihood of a psychiatric disorder increased dramatically with increasing numbers of physical symptoms. The prevalence of a mood disorder in patients with 0 to 1, 2 to 3, 4 to 5, 6 to 8, and 9 or more symptoms was 2%, 12%, 23%, 44%, and 60%, respectively, and the prevalence of an anxiety disorder was 1%, 7%, 13%, 30%, and 48%, respectively. Finally, each physical symptom was associated with significant functional impairment; indeed, the number of physical symptoms was a powerful correlate of functional status. CONCLUSIONS: The number of physical symptoms is highly predictive for psychiatric disorders and functional impairment. Multiple or unexplained symptoms may signify a potentially treatable mood or anxiety disorder.

Association of binge eating disorder and psychiatric comorbidity in obese subjects.

OBJECTIVE: The authors determined the prevalence of binge eating disorder in a self-referred study group of moderately and severely obese subjects and investigated whether binge eating disorder was associated with psychiatric disorders, a history of psychotherapy, a family history of psychiatric illness, or a history of sexual abuse. METHOD: They interviewed 89 obese women and 39 obese men (body mass index > 30 kg/m2) who were not currently in weight loss treatment, using the Binge Eating Disorder Clinical Interview, the Structured Clinical Interview for DSM-III-R, and the Structured Clinical Interview for DSM-III-R Personality Disorders. RESULTS: Forty-three (34%) of the subjects met criteria for binge eating disorder--33 women and 10 men. Black and white subjects had similar rates of binge eating disorder. Subjects with binge eating disorder were significantly more likely than those without the disorder to have a lifetime prevalence of a DSM-III-R axis I or axis II diagnosis and to have undergone psychotherapy or counseling. The lifetime rates of major depression, panic disorder, bulimia nervosa, borderline personality disorder, and avoidant personality disorder were all significantly higher in subjects with binge eating disorder. The rate of reported sexual abuse was not higher among subjects with binge eating disorder; however, they were significantly more likely to have a family history of substance abuse. The relative risks for psychiatric disorders were higher in both moderately and severely obese subjects with binge eating disorder than in those without the disorder. CONCLUSIONS: Among both moderately and severely obese subjects, binge eating disorder is associated with higher rates of axis I and axis II psychiatric disorders.

The reliability of three definitions of bizarre delusions.

OBJECTIVE: This study was conducted to determine whether the interjudge reliability of the DSM-III-R concept of bizarre delusions could be improved by alternative definitions of the concept. METHOD: Twelve raters evaluated 180 delusions of separate psychiatric patients according to the DSM-III-R and two alternative definitions of bizarre delusions. RESULTS: The kappas for the DSM-III-R definition and for one of the alternative definitions were 0.64 and 0.65, respectively; for the other alternative definition it was 0.45. All three definitions were highly intercorrelated, largely identifying the same cases. CONCLUSIONS: Neither of the alternative definitions of bizarre delusions was more reliable than the DSM-III-R definition. The reliability of the DSM-III-R definition, although only fair, is comparable to that of other important clinical concepts that play a major role in the DSM-III-R diagnostic criteria for psychotic disorders.

Binge eating disorder: its further validation in a multisite study.

Binge eating disorder (BED) is a new eating disorder that describes the eating disturbance of a large number of individuals who suffer from recurrent binge eating but who do not regularly engage in the compensatory behaviors to avoid weight gain seen in bulimia nervosa. This multisite study of BED involved 1,785 subjects drawn from 18 weight control programs, 942 subjects from five nonpatient community samples, and 75 patients with bulimia nervosa. Approximately 29% of subjects in weight control programs met the criteria for BED. In the nonpatient community samples BED was more common than purging bulimia nervosa. The validity of BED was supported by its strong association with (1) impairment in work and social functioning, (2) overconcern with body/shape and weight, (3) general psychopathology, (4) significant amount of time in adult life on diets, (5) a history of depression, alcohol/drug abuse, and treatment for emotional problems.

Binge eating disorder should be included in DSM-IV: a reply to Fairburn et al.'s "the classification of recurrent overeating: the binge eating disorder proposal".

Extensive recent research supports a proposal that a new eating disorder, binge eating disorder (BED), be included in DSM-IV. BED criteria define a relatively pure group of individuals who are distressed by recurrent binge eating who do not exhibit the compensatory features of bulimia nervosa. This large number of patients currently can only be diagnosed as eating disorder not otherwise specified (EDNOS). Recognizing this new disorder will help stimulate research and clinical programs for these patients. Fairburn et al.'s critique of BED fails to acknowledge the large body of knowledge that indicates that BED represents a distinct and definable subgroup of eating disordered patients and that the diagnosis provides useful information about psychopathology, prognosis, and outcome (Fairburn, Welch, & Hay [in press]. The classification of recurrent overeating: The "binge eating disorder" proposal. International Journal of Eating Disorders.) Against any reasonable standard for adding a new diagnosis to DSM-IV, BED meets the test.

The Structured Clinical Interview for DSM-III-R (SCID). I: History, rationale, and description.

The history, rationale, and development of the Structured Clinical Interview for DSM-III-R (SCID) is described. The SCID is a semistructured interview for making the major Axis I DSM-III-R diagnoses. It is administered by a clinician and includes an introductory overview followed by nine modules, seven of which represent the major axis I diagnostic classes. Because of its modular construction, it can be adapted for use in studies in which particular diagnoses are not of interest. Using a decision tree approach, the SCID guides the clinician in testing diagnostic hypotheses as the interview is conducted. The output of the SCID is a record of the presence or absence of each of the disorders being considered, for current episode (past month) and for lifetime occurrence.

The Structured Clinical Interview for DSM-III-R (SCID). II. Multisite test-retest reliability.

A test-retest reliability study of the Structured Clinical Interview for DSM-III-R was conducted on 592 subjects in four patient and two nonpatient sites in this country as well as one patient site in Germany. For most of the major categories, kappa s for current and lifetime diagnoses in the patient samples were above .60, with an overall weighted kappa of .61 for current and .68 for lifetime diagnoses. For the nonpatients, however, agreement was considerably lower, with a mean kappa of .37 for current and .51 for lifetime diagnoses. These values for the patient and nonpatient samples are roughly comparable to those obtained with other structured diagnostic instruments. Sources of diagnostic disagreement, such as inadequate training of interviewers, information variance, and low base rates for many disorders, are discussed.

A structured diagnostic interview for hypochondriasis. A proposed criterion standard.

We developed a structured diagnostic interview for DSM-III-R hypochondriasis (SDIH) that is the first such clinician-administered instrument. The SDIH was administered to 88 general medical outpatients who scored above a predetermined cutoff on a hypochondriacal symptom questionnaire, and to 100 comparison patients randomly chosen from among those below the cutoff. Using the joint assessment method, interrater agreement on the DSM-III-R diagnostic criteria was 88% to 97% and agreement on the diagnosis was 96%. Concurrent validity was suggested by a significant correlation between the interview and the primary care physicians' ratings of hypochondriasis. A measure of external validity was demonstrated in that several clinical characteristics thought to be ancillary features of hypochondriasis were significantly more prevalent in interview-positive patients than in interview-negative patients. Finally, the SDIH appeared to have discriminant validity in that patients diagnosed as hypochondriacal had several other clinical features that distinguished them from the patients who scored above the cutoff on hypochondriacal symptomatology, but failed to be diagnosed as hypochondriacal with the SDIH.

Reliability of dual diagnosis. Substance dependence and psychiatric disorders.

The Structured Clinical Interview for DSM-III-R was used to examine the effects of the co-occurrence of psychiatric and substance dependence disorders on diagnostic reliability. The test-retest reliability over a 1-week period was studied in groups of: a) individuals with current substance abuse diagnoses (N = 97), b) individuals with past, but not current, drug histories (N = 146), and c) individuals without substance abuse diagnoses (N = 356; primarily psychiatric patients). A measurement of reliability (Kappa coefficients) was estimated for four general psychiatric categories (psychotic, mood, anxiety, and eating disorders), along with specific most-frequent diagnoses in each category (schizophrenia, major depression, panic disorders, and bulimia nervosa, respectively). Past use and non-drug-use groups were similar in their generally reliable reporting of current and past psychiatric disorders. However, current mood and psychotic disorders were less reliably diagnosed in the group with current substance use disorders.

Now is the time to retire the term "organic mental disorders".

The organic/nonorganic distinction in contemporary classifications of mental disorders such as DSM-III and DSM-III-R has important prognostic and treatment implications, because it directs the clinician to pay special attention to the possibility of an underlying "physical" disorder as the cause of the mental disturbance. However, the term "organic" raises serious and intractable problems, since the connotative meaning of the term always returns to its historical roots, which imply an outmoded functional/structural, psychological/biological, and mind/body dualism. The authors present a proposal being considered for DSM-IV that would eliminate the term "organic" and reorganize the classification of organic mental disorders. Disorders previously referred to as "organic mental disorders" would be renamed as either "secondary disorders" (if they are due to "physical" disorders) or "substance-induced disorders." The entire classification of mental disorders would be reorganized to distribute the secondary and substance-induced disorders into the major groups with which they share phenomenology. The traditional organic mental disorders--delirium, dementia, and amnestic disorder--would be grouped together under the rubric of "cognitive impairment disorders." While acknowledging problems with the suggested new terminology and reorganization of the classification, the authors argue that the potential benefits of the proposal for clarity and for facilitating differential diagnosis justify putting to rest the familiar but now anachronistic term "organic mental disorders."

International reliability of a diagnostic intake procedure for panic disorder.

Test-retest diagnostic reliability interviews using the Upjohn version of the Structured Clinical Interview for DSM-III (SCID) were conducted with 72 patients at 13 international sites of the Cross-National Collaborative Panic Study. Agreement on the diagnosis of panic disorder was very good. For the subtypes (uncomplicated, with limited phobic avoidance, and agoraphobia), agreement was fair to good.

An outsider-insider's views about revising the DSMs.

After having a leadership role in the development of the 3rd edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III; American Psychiatric Association, 1980) and its revision (DSM-III-R; American Psychiatric Association, 1987), I now comment as an outsider-insider on the development of DSM-IV. Many features of the DSM-IV process, such as systematic literature reviews and focused field trials, represent significant advances that will increase the role of empirical findings in the decision-making process in this latest edition of the DSM. However, it is likely that when final decisions are made about DSM-IV, the decisions will still be based primarily on expert consensus, rather than on data, as was the case with DSM-III and DSM-III-R.
