Use of psychiatric emergency services and enrollment status in a public managed mental health care plan.
OBJECTIVE: This study examined the sociodemographic and clinical characteristics of acute-care psychiatric patients who visited the emergency department at a large public hospital in terms of the patients' enrollment status in the region's public managed mental health care plan. The results of the analyses were expected to provide information about the degree and types of access to care for individuals who are and are not enrolled in the plan. METHODS: Data were collected over a seven-month period for 2,419 patients who visited a large, inner-city crisis triage unit. Patients were grouped according to whether they were currently enrolled, previously enrolled, or never enrolled in the public managed mental health care plan. Univariate and logistic regression models were used to determine differences between the three groups. RESULTS: In general, patients who were currently enrolled in the plan had a higher rate of functional psychosis, past use of psychiatric services, and functional disability and lower rates of substance use and homelessness. Previously enrolled patients had a more moderate rate of psychosis but a higher rate of substance use, functional disability, and homelessness. The never-enrolled patients had a lower rate of psychosis, functional disability, and past use of psychiatric services, and moderate substance use. CONCLUSIONS: The region's public health plan appeared to be succeeding in engaging and keeping the most psychiatrically impaired patients in treatment; however, individuals with moderate psychiatric symptoms and high levels of substance abuse may never have been enrolled in the plan because of Medicaid ineligibility or because they dropped out of treatment. Problematic behavior and history of hospitalization were the best predictors of enrollment status.

Stressful life events and impulsiveness in failed suicide.
The relationship of recent stressful life events with impulsiveness in triggering suicide attempts and how impulsiveness changes from one suicide attempt to another is unclear. This study used structured-interview tools and standardized measurements to examine the relationship between life stress and impulsiveness in a sample of patients who required hospitalization for a medically serious suicide attempt. After controlling for potentially confounding variables, the number of disrupted interpersonal relationships in the preceding year was a significant predictor of the impulsiveness of the suicide attempt, with three or more losses (but not other life stresses) associated with less impulsive attempts (T = 2.4, p = .02). Female gender (T = -1.98, p = .05) and lifetime DMS-III-R diagnoses (T = -2.45, p = .02) were significantly associated with more impulsive attempts. In 55 patients with at least two suicide attempts, impulsiveness, lethal intent, and communication of intent were significantly greater for the present compared to the prior attempt (p = 0.000). Certain stressful life events, gender, and total lifetime DSM-III-R diagnoses are associated with impulsiveness of failed suicide attempts; yet, impulsiveness is not necessarily consistent from one suicide attempt to another. This evidence supports and amplifies a stress-diathesis model of suicide behavior. Accordingly, efforts to increase personal resilience in individuals who have "failed suicide" may be more effective at preventing suicide morbidity than simple stress-reduction measures alone.

Attention-deficit/hyperactivity disorder and learning disabilities in adults.
Attention-Deficit/Hyperactivity Disorder (ADHD) is a developmental disorder which begins in childhood. It is now recognized that ADHD persists into adolescence and adulthood in the majority of cases. Significant psychiatric comorbidity, particularly substance abuse, antisocial personality disorder, and mood and anxiety disorders occurs in adolescent and adult ADHD. Perhaps one fifth of childhood cases of ADHD may also have co-morbid learning disorder. Significant legal, academic, social, and occupational problems have been observed in adults with ADHD. The clinician faces a diagnostic and treatment challenge in trying to determine whether ADHD and learning disabilities (LDs) are present in the adult patient. Treatment and recommendations for accommodations in institutions of higher education and the workplace may rest on accurate discrimination between ADHD and LD.

Reliability and validity of screening instruments for drug and alcohol abuse in adults seeking evaluation for attention-deficit/hyperactivity disorder.
A growing number of adults are seeking evaluation for Attention-Deficit/Hyperactivity Disorder (ADHD). Screening for substance use disorders should be included as part of any comprehensive ADHD evaluation. We describe the validity and reliability of the Drug Abuse Screening Test (DAST) and the Alcohol Use Disorders Identification Test (AUDIT) in adults seeking evaluation for ADHD. Internal reliability estimates were excellent for both instruments. Scores on the DAST and AUDIT were higher among patients with a DSM-IV diagnosis of current drug abuse or dependence or current alcohol abuse or dependence, respectively. A cutoff score of 6 or above appears to be optimal for identifying individuals who are current drug abusers. A cutoff score of 6 or above on the AUDIT is suggested for detection of current alcohol abuse in this population. Comparable rates of substance use disorders were observed in ADHD and non-ADHD patients. Both measures are valid and reliable instruments for screening for alcohol and drug abuse among adults seeking evaluation for ADHD.

Shorter hospital stays and more rapid improvement among patients with schizophrenia and substance disorders.
OBJECTIVE: Length of stay and treatment response of inpatients with acute schizophrenia were examined to determine whether differences existed between those with and without comorbid substance-related problems. METHODS: The sample comprised 608 patients with a diagnosis of schizophrenia or schizoaffective disorder treated on hospital units with integrated dual diagnosis treatment. They were rated on admission and discharge by a psychiatrist using a structured clinical instrument. Patients with no substance-related problems were compared with those with moderate to severe problems using t tests, chi square tests, and analysis of variance. RESULTS: When analyses controlled for age, gender, and other clinical variables, dually diagnosed patients were found to have improved markedly faster compared with patients without a dual diagnosis. Their hospital stays were 30 percent shorter on both voluntary and involuntary units. They also showed somewhat greater symptomatic improvement and no increase in 18-month readmission rates. On admission the dual diagnosis group was more likely to be younger, male, and homeless and more likely to be a danger to self and others. Severity of psychosis was the same at admission for the two groups, but the dually diagnosed patients were rated as less psychotic at discharge. CONCLUSIONS: Dually diagnosed patients with schizophrenia appear to stabilize faster during acute hospitalization than those without a dual diagnosis. The authors hypothesize that substance abuse may temporarily amplify symptoms or that these patients may have a higher prevalence of better-prognosis schizophrenia. The availability of integrated dual-focus inpatient treatment and a well-developed outpatient system may also have helped these patients recover more rapidly.

Discriminant validity of the Wender Utah Rating Scale for attention-deficit/hyperactivity disorder in adults.
The authors examined the factor structure and discriminant validity of the Wender Utah Rating Scale (WURS) in adults seeking evaluation for attention-deficit/hyperactivity disorder (ADHD). Three factors (Dysthymia, Oppositional/Defiant Behavior, and School Problems) accounted for 59.4% of the variance. In a stepwise discriminant function analysis, age and childhood school problems emerged as significant variables. The classification procedure correctly classified 64.5% of patients. Among those who did not have ADHD, only 57.5% were correctly classified compared with 72.1% among those with ADHD. The WURS is sensitive in detecting ADHD, but it misclassifies approximately half of those who do not have ADHD.

Placebo-controlled, multicenter study of sertraline treatment for obsessive-compulsive disorder.
The safety and efficacy of sertraline versus placebo were examined in a group of nondepressed outpatients with obsessive-compulsive disorder (OCD). Patients with moderate-to-severe OCD were recruited at 10 sites. After a 1-week placebo lead-in, patients were treated in a double-blind fashion for 12 weeks with sertraline or placebo. Sertraline was administered at a starting dose of 50 mg/day, with flexible titration up to 200 mg/day. The efficacy measures were the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), the National Institute of Mental Health Global Obsessive Compulsive Scale (NIMH), and the Clinical Global Impression Scale (CGI) Severity of Illness and Improvement subscales. One hundred sixty-seven patients were randomly assigned and received at least one dose of double-blind medication: 86 received sertraline and 81 received placebo. All efficacy measures showed significantly greater improvement in the sertraline group from the end of week 8 until the end of week 12. Significantly greater improvement (p < 0.05) in the sertraline group first became apparent by the end of week 3 on the Y-BOCS and the CGI Improvement scale, and by the end of weeks 6 and 8, respectively, on the NIMH and CGI Severity scale. Sertraline was well tolerated, without serious adverse effects. In conclusion, sertraline was safe and effective in the treatment of patients with OCD.

A brief medical necessity scale for mental disorders: reliability, validity, and clinical utility.
Managed care organizations (MCOs) use the concept of "medical necessity" to decide whether a prescribed treatment is warranted for a given medical condition. Because mental disorders lack the objective disease criteria common to medical illness, behavioral health administrators need a validated means to identify and quantify the severity of "medically important" aspects of mental disorders. The authors developed and tested a brief medical necessity scale for mental disorders in 205 patients presenting for initial evaluation. The scale had a factor structure with four subscales; good internal consistency, interrater reliability, and concurrent and predictive validity; and modest ability to identify patients requiring hospitalization and, in hospitalized patients, those requiring involuntary hospitalization. The authors propose use of the scale to better clarify decisions about level of care assignments and to better assess patient characteristics predictive of good outcome.

The MOS 36-Item Short Form Health Survey: reliability, validity, and preliminary findings in schizophrenic outpatients.
OBJECTIVES: The authors test the reliability and validity of the Medical Outcomes Study Short Form 36-Item Health Survey (SF-36) as a written, self-administered survey in outpatients with chronic schizophrenia. METHODS: Thirty-six schizophrenic outpatients completed a written and oral form of the SF-36. A psychiatrist rated the patients using the Brief Psychiatric Rating Scale to determine severity of psychopathology. Cognitive functioning and academic achievement were also assessed. Internal consistency, test-retest reliability, concurrent and discriminative validity of the oral and written versions were determined. RESULTS: The SF-36 in both forms was shown to have good internal consistency, stability, and concurrent validity. The mental health SF-36 subscales had poor discriminant validity, compared with the physical functioning scale that demonstrated good discriminant validity. CONCLUSIONS: The validity of using the written form of the SF-36 on a sample of patients with chronic mental illness was demonstrated. The SF-36 appears to be an appropriate outcome measure for changes in physical and role functioning in consumers of outpatient mental health programs.

Mental illness and nursing home reform: OBRA-87 ten years later. Omnibus Budget Reconciliation Act.
OBJECTIVE: This literature review examined data on the effects of nursing home reform initiated by the Omnibus Budget Reconciliation Act of 1987 (OBRA), with particular attention to use of antipsychotic medications, use of physical restraints, and preadmission screening. METHODS: Data on the outcomes of the nursing home reform were obtained from a MEDLINE search of peer-reviewed articles from January 1985 through January 1997 and from PsycINFO from 1967 through 1997. RESULTS AND CONCLUSIONS: Survey and observational data suggest that the reform legislation is having the intended impact, especially in reducing the use of antipsychotic medications and physical restraints in nursing homes. Preadmission screening of nursing home residents with mental illness is the most widely criticized component of the reform, and the component that has been the subject of the fewest data-based studies. More data are needed to describe the economic costs of the reform and to link the reform to improvements in nursing home residents' quality of life.

Cardiovascular and catecholamine response to orthostasis in panic and obsessive-compulsive disorder and normal controls: effects of anxiety and novelty.
OBJECTIVE: Studies of the cardiovascular and catecholamine response to orthostatic challenge in panic disorder patients have yielded conflicting results. Failure to control for the effects of both anxiety and novelty, which contribute to subjects' response to orthostatic challenge in control patients, could possibly account for this. METHODS: The blood pressure, pulse, plasma norepinephrine and epinephrine responses to orthostasis were examined in patients with panic disorder, obsessive-compulsive disorder (to control for nonspecific anxiety effects), and controls, on two separate days a week apart (to control for novelty). RESULTS: All measures showed robust and significant increases with orthostatic challenge that were generally similar across groups. Pressure responses were greater on average on the first compared with the second day and panic disorder patients had higher plasma norepinephrine levels throughout the study and a diminished diastolic blood pressure response on the first day. CONCLUSIONS: These findings in general support the absence of consistent peripheral autonomic nervous system differences in response to orthostatic challenge in panic disorder patients.

The relationship of patient-administered outcome assessments to quality of life and physician ratings: validity of the BASIS-32.
The reliability and validity of a patient-administered version of the Behavior and Symptom Identification Scale (BASIS-32) was compared to the original interviewer-administered version. The construct validity of BASIS-32 subscales was assessed by examining their relationship with functional and satisfaction quality of life and physician ratings of functional and clinical status. A total of 361 acute psychiatric inpatients were given a self-administered BASIS-32, nurse-administered Lehman's Quality of Life Interview (QOLI), and Psychiatrist Assessment Form at admission and discharge. The original factor structure, internal consistency reliability, discriminant validity, and sensitivity to change were replicated. The patient-administered BASIS-32 is equally as reliable and valid as the interview. Construct validity analyses revealed that functional and satisfaction QOLI indices were moderately related to the BASIS-32 in the hypothesized directions. All satisfaction scales were associated with significantly less severity. Physician ratings were only mildly related to the subscales. The BASIS-32 used in outcome assessments with inpatients provides important and unique perspectives on functional and clinical status that are not tapped by clinician-rated assessments.

Longitudinal assessment of quality of life in acute psychiatric inpatients: reliability and validity.
This study examined the reliability, validity, and responsiveness of Lehman's Quality of Life Interview (QOLI) as an outcome measure on 981 acutely ill psychiatric inpatients assessed longitudinally at admission and discharge. Patients were stratified into five diagnostic (DX) (depressed bipolar, depressed unipolar, schizophrenia, mania, and other diagnoses) and two substance use disorder (SA) strata (with and without concurrent substance abuse/dependence) based on DSM-III-R criteria. There was good replication of the factor structure, excellent internal consistency, overall and within DX and SA groups. Intercorrelations showed that the functional and satisfaction indices measure unique aspects of the quality of life. The construct consistency of the QOLI was dependent upon psychiatric diagnosis and life domain. Intercorrelations of functional and satisfaction indices for patients with depression were greater than for manic patients. We demonstrated strong consistency of construct validity for family and social relation domains, but not safety or leisure activities. Construct validity was shown to hold longitudinally. Analyses of DX and SA group differences on satisfaction and functional indices of the 8 life domains supported discriminative validity: Depressed patients reported the most dissatisfaction, followed by schizophrenic patients, and manic patients reported the greatest satisfaction in most life domains. Patients with concurrent substance abuse generally reported less satisfaction and lower quality of life than patients without a dual diagnosis. Examination of longitudinal changes in satisfaction indicated the QOLI is responsive to changes in global life, leisure activities, living situation, and social relations from hospital admission to discharge (an average of 2 weeks). This study supports the use of the QOLI as an outcome measure to assess quality of life in acutely ill hospitalized psychiatric patients.

Psychiatric status, quality of life, and level of care as predictors of outcomes of acute inpatient treatment.
OBJECTIVE: The study examined the role of five types of variables--demographic characteristics, psychiatric status, functional quality of life, satisfaction with quality of life, and level of care--in predicting key outcomes of inpatient treatment. METHODS: Multivariate canonical regression and univariate multiple regression models were constructed using data from 1,053 inpatients at a public hospital in Washington State. The models were used to predict length of stay, change in symptom severity during hospitalization, psychiatrists' ratings of patients' insight into their illness at discharge, patients' global satisfaction with life, and rehospitalization within 18 months. Hierarchical stepwise procedures were used to select variables that were significant predictors of outcomes. RESULTS: All five classes of predictors were related to the outcomes. The roles of demographic characteristics and diagnoses were minimal. Previous hospitalization and severity of symptoms at admission were strong predictors of psychiatric status. Indicators of functional quality of life and satisfaction with quality of life explained significant variance in all models after accounting for the other classes of predictors. Frequency of family visits was the strongest functional quality-of-life predictor, relating to positive outcomes. Pretreatment satisfaction with life was a significant predictor of most outcomes, and increased satisfaction was associated with positive outcomes. CONCLUSIONS: Patients' quality of life before psychiatric inpatient treatment predicted treatment outcomes independently of psychiatric status, demographic characteristics, and level-of-care variables. Prospective studies are needed to predict outcomes using multidimensional constructs.

Reduced benzodiazepine sensitivity in patients with panic disorder: comparison with patients with obsessive-compulsive disorder and normal subjects.
OBJECTIVE: The authors sought to replicate their previous finding of reduced response to diazepam in patients with panic disorder, to test whether this effect was specific for panic disorder, and to determine whether this reduced response was merely an artifact of resistance to sedation from anxiety-related overarousal. METHOD: The effects of four increasing intravenous doses of diazepam on saccadic eye movement velocity and accuracy (the latter being a saccadic variable that is unaffected by sedation), short-term memory, and self- and observer-rated sedation were assessed in 18 patients with panic disorder, 15 patients with obsessive-compulsive disorder, and 14 normal comparison subjects. The ratios of effect to blood level areas under the curve for both ascending and descending limbs of the effect/blood level curves were compared for each variable. RESULTS: Patients with panic disorder showed significantly less diazepam effect on saccadic velocity and accuracy for the ascending limb of the blood level curve than comparison subjects. Patients with obsessive-compulsive disorder showed similar differences from comparison subjects but only for saccadic velocity. There were no group differences in diazepam effects on memory and sedation. CONCLUSIONS: Patients with panic disorder are less sensitive than comparison subjects to diazepam. Although this difference is not an artifact of resistance to sedation, it may not be specific for panic disorder but rather may reflect a more nonspecific aspect of anxiety disorders.
