A computer method for assessing satisfaction with hearing aids.

The purpose of this study was to evaluate a new clinical assessment, the Dynamic Assessment of Hearing Aids (DAHA), for a large clinical population. Unlike traditional questionnaire methods, the DAHA has patients use an intuitive graphical computer interface to record visual analogue ratings of satisfaction with various features of their hearing aids (e.g. clarity, cost, appearance). Data were collected from 191 participants.A subset of participants returned for retest. The DAHA items assess satisfaction with hearing aids within four domains: communication, physical features, sound quality, and personal reactions. The concurrent validity was determined by comparing DAHA results to those obtained with the satisfaction with amplification in daily life (SADL). Ratings for personal reactions to hearing aids indicate the most satisfaction, and ratings for communication (especially group conversations and phone use) indicate the least satisfaction. The DAHA total score was found to have good test/retest and high internal consistency. Concurrent validity was supported by a strong correlation between total scores on the DAHA and the SADL. Results suggest the DAHA maybe an effective tool for clinical use.

Women, Co-occurring Disorders, and Violence Study: evaluation design and study population.

The Women, Co-occurring Disorders, and Violence Study (WCDVS) was a multi-site cooperative study to evaluate new service models for women with co-occurring mental health and substance use disorders and a history of physical and/or sexual abuse. Despite common features in the service interventions and evaluation procedures, diversity across the nine sites plus differences introduced by non-random assignment led to numerous methodological challenges. This article describes the design, measurement, and analysis decisions behind the WCDVS and lays the foundation for understanding participant-level outcomes and service costs. This article also describes the study population, as recruited and following attrition at the 6-month follow-up, in order to address the threat of selection bias to inferences drawn from this multi-site study.

Reliability of instruments in a cooperative, multisite study: employment intervention demonstration program.

Reliability of well-known instruments was examined in 202 people with severe mental illness participating in a multisite vocational study. We examined interrater reliability of the Positive and Negative Syndrome Scale (PANSS) and the internal consistency and test-retest reliability of the PANSS, the Rosenberg Self-Esteem Scale, the Medical Outcomes Study Short Form-36 (SF-36), and the Quality of Life Interview. Most scales had good levels of reliability, with intraclass correlation coefficients (ICCs) and coefficient alphas above .70. However, the SF-36 scales were generally less stable over time, particularly Social Functioning (ICC = .55). Test-retest reliability was lower among less educated respondents and among ethnic minorities. We recommend close monitoring of psychometric issues in future multisite studies.

Does competitive employment improve nonvocational outcomes for people with severe mental illness?

The authors examined the cumulative effects of work on symptoms, quality of life, and self-esteem for 149 unemployed clients with severe mental illness receiving vocational rehabilitation. Nonvocational measures were assessed at 6-month intervals throughout the 18-month study period, and vocational activity was tracked continuously. On the basis of their predominant work activity over the study period, participants were classified into 4 groups: competitive work, sheltered work, minimal work, and no work. The groups did not differ at baseline on any of the nonvocational measures. Using mixed effects regression analysis to examine rates of change over time, the authors found that the competitive work group showed higher rates of improvement in symptoms; in satisfaction with vocational services, leisure, and finances; and in self-esteem than did participants in a combined minimal work-no work group. The sheltered work group showed no such advantage.

Converting day treatment centers to supported employment programs in Rhode Island.

OBJECTIVE: The purpose of the study was to compare vocational and nonvocational outcomes of clients of two community mental health centers that underwent conversion from day treatment programs to supported employment programs with outcomes of clients of a center that delayed conversion until after the study was completed. METHODS: As part of a statewide effort in Rhode Island to convert day treatment programs to supported employment programs, the authors assessed 127 day treatment clients with severe mental illness in three community mental health centers. Two of the centers converted to supported employment, and one continued its rehabilitative day program. Participants were assessed prospectively for 30 to 36 months, with special attention to vocational and social outcomes. RESULTS: Former day treatment clients in the converted centers attained higher rates of competitive employment than those in the comparison group (44.2 percent and 56.7 percent versus 19.5 percent). Other employment outcomes also improved, and hospitalization rates and overall social functioning were unchanged. CONCLUSIONS: This study supports findings of previous studies suggesting that replacing rehabilitative day treatment programs with supported employment programs yields improvements in employment outcomes without adverse effects.

Psychophysiological reactivity in female sexual abuse survivors.

This study examined psychophysiological reactivity in 37 female childhood sexual abuse (CSA) survivors. After assessment of posttraumatic stress disorder (PTSD), psychiatric comorbidity, and trauma history, we conducted a psychophysiological assessment of forehead muscle tension, electrodermal activity, and heart rate during a mental arithmetic task and4 script-driven imagery tasks (neutral, consensual sex, pleasant, and trauma). PTSD symptom severity correlated positively with psychophysiologic changes and negative emotions during the trauma imagery task. During mental arithmetic, PTSD symptom severity correlated negatively with autonomic changes and positively with negative emotions. These results extend earlier PTSD research showing trauma-specific increased psychophysiological reactivity related to CSA in women with PTSD. They further suggest a negative association between PTSD severity and autonomic reactions to mental arithmetic.

The effects of clozapine on alcohol and drug use disorders among patients with schizophrenia.

Several case studies indicate that clozapine use is associated with reductions in the use of nicotine, alcohol, or illicit drugs. Although not designed to assess clozapine, this study explored a posteriori the effects of clozapine on alcohol and drug use disorders among schizophrenia patients. Among 151 patients with schizophrenia or schizoaffective disorder and co-occurring substance use disorder who were studied in a dual-disorder treatment program, 36 received clozapine during the study for standard clinical indications. All participants were assessed prospectively at baseline and every 6 months over 3 years for psychiatric symptoms and substance use. Alcohol-abusing patients taking clozapine experienced significant reductions in severity of alcohol abuse and days of alcohol use while on clozapine. For example, they averaged 54.1 drinking days during 6-month intervals while off clozapine and 12.5 drinking days while on clozapine. They also improved more than patients who did not receive clozapine. At the end of the study, 79.0 percent of the patients on clozapine were in remission from alcohol use disorder for 6 months or longer, while only 33.7 percent of those not taking clozapine were remitted. Findings related to other drugs in relation to clozapine were also positive but less clear because of the small number of patients with drug use disorders. This study was limited by the naturalistic design and the lack of prospective, standardized measures of clozapine use. The use of clozapine by patients with co-occurring substance disorders deserves further study in randomized clinical trials.

Acute stress disorder symptomatology during hospitalization for pediatric injury.

OBJECTIVE: To examine and identify predictors of acute stress disorder (ASD) and ASD symptomatology (ASDS) in children hospitalized for injuries. METHOD: Fifty-four youths were assessed while hospitalized for injuries. Dependent variables were parent and nurse ratings of children's ASDS. Independent variables included children's prior trauma exposure and behavior problems, injury severity and permanence, brain injury, injury or death to family/friend(s), parental distress, and child reports of the injury/hospitalization experience as meeting criterion A for ASD. RESULTS: A total of 92.6% of children felt the current experience met criterion A, compared with 64.8% of parents. According to parent questionnaires, 4 subjects (7.4%) met DSM-IV criteria for ASD while another 12 (22.2%) had clinically significant but subsyndromal ASDS. Children's ASDS, as reported by parents, correlated highly with parental distress and ratings of children's prior psychopathology, and modestly with injury severity and family/friend(s) injured or killed. Nurses' ratings of children's ASDS correlated strictly with injury- and accident-related variables, and not with parent ratings of children's ASDS. CONCLUSIONS: Children perceive injuries and hospitalizations as stressful. ASDS is widely though divergently reported by parents and nurses in children hospitalized for injury. Parental distress, children's prior psychopathology, and injury-related factors may be useful predictors of children's postinjury ASDS.

Predicting posttraumatic stress after hospitalization for pediatric injury.

OBJECTIVE: To determine the prevalence and predictors of posttraumatic stress disorder (PTSD) in children after hospitalizations for accidental injuries. METHOD: Forty-eight children (aged 7-17 years) and their parents were assessed during hospitalization with measures of children's prior traumatization, prior psychopathology, injury severity, parental acute distress, and child acute distress. At outpatient follow-up at least 1 month later, children were evaluated for current PTSD diagnosis and PTSD symptomatology (PTSDS) by a child structured interview and for PTSDS by a parent questionnaire. RESULTS: A total of 12.5% had the full syndrome of PTSD at follow-up, and an additional 16.7% had partial (sub-syndromal) PTSD. Full PTSD was associated with a higher level of prior psychopathology, higher parental acute distress, and higher rates of prior sexual abuse, compared with partial or no PTSD. Prior psychopathology, parental distress, and, to a lesser extent, children's acute distress as reported by parents and breadth of prior traumatization, predicted subsequent PTSDS. CONCLUSIONS: Full or partial PTSD is relatively common in youths 1 month or more after hospitalization for injuries. Parents' acute distress as well as children's prior psychopathology, prior traumatization, and acute distress may be useful predictors of such injured children's subsequent PTSD or PTSDS.

A randomized clinical trial of supported employment for inner-city patients with severe mental disorders.

BACKGROUND: This experiment evaluated the effectiveness of 2 approaches to vocational services for persons with severe mental disorders: (1) individual placement and support (IPS), in which employment specialists within the mental health center help patients to obtain competitive jobs and provide ongoing support, and (2) enhanced vocational rehabilitation (EVR), in which stepwise vocational services are delivered by rehabilitation agencies. METHODS: One hundred fifty-two unemployed, inner-city patients with severe mental disorders who expressed interest in competitive employment were randomly assigned to IPS or EVR and followed up for 18 months. Following diagnostic assessment, participants were assessed with standardized measures of work, income, self-esteem, quality of life, symptoms, and hospitalization at baseline and at 6-, 12-, and 18-month follow-up evaluations. Employment was tracked monthly and job satisfaction every 2 months. RESULTS: During the 18-month study, participants in the IPS program were more likely to become competitively employed (60.8% vs 9.2%) and to work at least 20 hours per week in a competitive job (45.9% vs 5.3%), whereas EVR participants had a higher rate of participation in sheltered employment (71.1% vs 10.8%). Total earnings, job satisfaction, and nonvocational outcomes were similarly improved for both groups. CONCLUSION: The IPS model of supported employment is more effective than standard, stepwise EVR approaches for achieving competitive employment, even for inner-city patients with poor work histories and multiple problems.

Fidelity to assertive community treatment and client outcomes in the New Hampshire dual disorders study.

OBJECTIVE: The study examined the association between fidelity of programs to the assertive community treatment model and client outcomes in dual disorders programs. METHODS: Assertive community treatment programs in the New Hampshire dual disorders study were classified as low-fidelity programs (three programs) or high-fidelity programs (four programs) based on extensive longitudinal process data. The study included 87 clients with a dual diagnosis of severe mental illness and a comorbid substance use disorder. Sixty-one clients were in the high-fidelity programs, and 26 were in the low-fidelity programs. Client outcomes were examined in the domains of substance abuse, housing, psychiatric symptoms, functional status, and quality of life, based on interviews conducted every six months for three years. RESULTS: Clients in the high-fidelity assertive community treatment programs showed greater reductions in alcohol and drug use and attained higher rates of remission from substance use disorders than clients in the low-fidelity programs. Clients in high-fidelity programs had higher rates of retention in treatment and fewer hospital admissions than those in low-fidelity programs. No differences between groups were found in length of hospital stays and other residential measures, psychiatric symptoms, family and social relations, satisfaction with services, and overall life satisfaction. CONCLUSIONS: Faithful implementation of, and adherence to, the assertive community treatment model for persons with dual disorders was associated with superior outcomes in the substance use domain. The findings underscore the value of measures of model fidelity, and they suggest that local modifications of the assertive community treatment model or failure to comply with it may jeopardize program success.

Legal system involvement and costs for persons in treatment for severe mental illness and substance use disorders.

OBJECTIVE: Persons with co-occurring severe mental illness and substance use disorders were followed for three years to better understand how they are involved with the legal system and to identify factors associated with different kinds of involvement. METHODS: Data came from a three-year study of 203 persons enrolled in specialized treatment for dual disorders. Cost and utilization data were collected from multiple data sources, including police, sheriffs and deputies, officers of the court, public defenders, prosecutors, private attorneys, local and county jails, state prisons, and paid legal guardians. RESULTS: Over three years 169 participants (83 percent) had contact with the legal system, and 90 (44 percent) were arrested at least once. Participants were four times more likely to have encounters with the legal system that did not result in arrest than they were to be arrested. Costs associated with nonarrest encounters were significantly less than costs associated with arrests. Mean costs per person associated with an arrest were $2,295, and mean costs associated with a nonarrest encounter were $385. Combined three-year costs averaged $2,680 per person. Arrests and incarcerations declined over time. Continued substance use and unstable housing were associated with a greater likelihood of arrest. Poor treatment engagement was associated with multiple arrests. Men were more likely to be arrested, and women were more likely to be the victims of crime. CONCLUSIONS: Effective treatment of substance use among persons with mental illness appears to reduce arrests and incarcerations but not the frequency of nonarrest encounters. Stable housing may also reduce the likelihood and number of arrests.

Review of integrated mental health and substance abuse treatment for patients with dual disorders.

Patients with severe mental disorders such as schizophrenia and co-occurring substance use disorders traditionally received treatments for their two disorders from two different sets of clinicians in parallel treatment systems. Dissatisfaction with this clinical tradition led to the development of integrated treatment models in which the same clinicians or teams of clinicians provide substance abuse treatment and mental health treatment in a coordinated fashion. We reviewed 36 research studies on the effectiveness of integrated treatment for dually diagnosed patients. Studies of adding dual-disorders groups to traditional services, studies of intensive integrated treatments in controlled settings, and studies of demonstration projects have thus far yielded disappointing results. On the other hand, 10 recent studies of comprehensive, integrated outpatient treatment programs provide encouraging evidence of the programs' potential to engage dually diagnosed patients in services and to help them reduce substance abuse and attain remission. Outcomes related to hospital use, psychiatric symptoms, and other domains are less consistent. Several program features appear to be associated with effectiveness: assertive outreach, case management, and a longitudinal, stage-wise, motivational approach to substance abuse treatment. Given the magnitude and severity of the problem of dual disorders, more controlled research on integrated treatment is needed.

Cost-effectiveness of assertive community treatment versus standard case management for persons with co-occurring severe mental illness and substance use disorders.

OBJECTIVE: To determine the cost-effectiveness of Assertive Community Treatment (ACT) in comparison to Standard Case Management (SCM) for persons with severe mental illness and substance use disorders. DATA SOURCES AND STUDY SETTING: Original data on the effectiveness and social costs of ACT and SCM that were collected between 1989 and 1995. Seven community mental health centers in New Hampshire provided both types of treatment. STUDY DESIGN: Persons with schizophrenia, schizoaffective disorder, or bipolar disorder and a concurrent substance use disorder were randomly assigned to ACT or SCM and followed for three years. The primary variables assessed were substance use, psychiatric symptoms, functioning, quality of life, and social costs. DATA COLLECTION METHODS: Effectiveness data were obtained from interviews at six-month intervals with persons enrolled in treatment and with their service providers. Social cost and service utilization data came from client reports; interviews with informal caregivers; provider information systems and Medicaid claims; law enforcement agencies; courts; and community service providers. PRINCIPAL FINDINGS: Participants in both groups showed significant reductions in substance use over time. Focusing on quality of life and substance use outcomes, ACT and SCM were not significantly different in cost-effectiveness over the entire three-year study period. Longitudinal analyses showed that SCM tended to be more efficient during the first two years but that ACT was significantly more efficient than SCM during the final year of the study. CONCLUSIONS: In an adequately funded system, ACT is not more cost-effective than SCM. However, ACT efficiency appears to improve over time.

Assertive community treatment for patients with co-occurring severe mental illness and substance use disorder: a clinical trial.

Integrated mental health and substance abuse treatment within an assertive community treatment (ACT) approach was compared to that within a standard case management approach for 223 patients with dual disorders over three years. ACT patients showed greater improvements on some measures of substance abuse and quality of life, but the groups were equivalent on most measures, including stable community days, hospital days, psychiatric symptoms, and remission of substance use disorder.

Methodological issues in assertive community treatment studies.

Recent evaluations of ACT programs have produced equivocal findings, often leading to the invocation of methodological problems as responsible for the lack of positive results. This paper discusses issues of theory and methodology as they pertain to improving research of ACT, with particular attention paid to issues of sampling, process evaluation, measurement, and data analysis.

Housing status among formerly homeless dually diagnosed adults.

OBJECTIVE: Residential outcomes of homeless adults with severe mental illness and a substance use disorder were studied over 18 months during which participants received integrated dual diagnosis services and housing supports based on a continuum model. METHODS: Interviews with 158 participants at baseline and at six-, 12-, and 18-month follow-ups assessed housing status, residential history, substance abuse and progress toward recovery, psychiatric symptoms, and quality of life. Complete data were available for 122 participants. If participants lived continuously in high-quality housing with no housing loss or nights of homelessness during the final six months of the study, they were classified as having stable housing. RESULTS: Of the 122 participants for whom complete data were available, 64 (52 percent) achieved stable housing. Most participants who achieved stable housing first entered staffed and supervised housing and then moved to independent arrangements by the end of the study. Stable housing during the final evaluation period was associated with lower substance use, greater progress toward substance abuse recovery, and higher quality of life. Final housing status was not predicted by baseline variables but was predicted by progress toward recovery during months 0 to 6 and 6 to 12 and by less severe drug use during months 6 to 12. Participants who abused no illicit drugs during months 6 to 12 were almost three times as likely to achieve stable housing as those who abused illicit drugs. CONCLUSIONS: Housing stability is strongly mediated by substance abuse and progress toward recovery. Nevertheless, when formerly homeless persons with dual diagnoses are provided integrated dual diagnosis treatment, they can gradually achieve stable housing.

Integrated treatment for dually diagnosed homeless adults.

This study examined the effects of integrating mental health, substance abuse, and housing interventions for homeless persons with co-occurring severe mental illness and substance use disorder. With the use of a quasi-experimental design, integrated treatment was compared with standard treatment for 217 homeless, dually diagnosed adults over an 18-month period. The integrated treatment group had fewer institutional days and more days in stable housing, made more progress toward recovery from substance abuse, and showed greater improvement of alcohol use disorders than the standard treatment group. Abuse of drugs other than alcohol (primarily cocaine) improved similarly for both groups. Secondary outcomes, such as psychiatric symptoms, functional status, and quality of life, also improved for both groups, with minimal group differences favoring integrated treatment.

Measuring hospital use without claims: a comparison of patient and provider reports.

OBJECTIVE: We compared the validity of hospital admission and length of stay reports from patients, outpatient providers, and hospitals, and we examined possible sources of error. DATA SOURCES: Data were collected from people enrolled in a randomized trial of treatment for severe mental illness and substance use disorders, from community mental health centers (CMHCs), and from hospitals. Reports for each of the 74 study participants covered two-year time periods beginning and ending at various times between 1989 and 1993. STUDY DESIGN: We compared reports from the various sources and constructed a hybrid with data from all three sources. Using parametric and non-parametric statistics, we compared patient, CMHC, and hospital reports with each other and with the hybrid source. In subsequent regression analyses we explored correlates of reporting accuracy. PRINCIPAL FINDINGS: Single-source reports underestimated hospital use, but when patient and CMHC reports were combined, results were very similar to those obtained by the more laborious hybrid method. Patient reports became less accurate as the time between discharge and reporting increased; people with bipolar disorders reported admissions with greater accuracy than did people with schizophrenia. CMHC reporting accuracy decreased as the distance to the admitting hospital increased and were less accurate for people with more severe psychiatric symptoms. CONCLUSIONS: Reports from single sources are likely to underestimate hospital use for different reasons. Combining carefully collected data from patients and outpatient providers produces estimates of hospital use that are substantially the same as those developed through methods that are more laborious and costly.

The New Hampshire study of supported employment for people with severe mental illness.

This study compared supported employment services in 2 contrasting programs: (a) Group Skills Training, a professional rehabilitation agency outside of the mental health center that provided pre-employment skills training and support in obtaining and maintaining jobs, or (b) the Individual Placement and Support (IPS) model, which integrated clinical and vocational services within the mental health center. People with severe mental disorders who expressed interest in competitive employment (N = 143) were randomly assigned to 1 of these 2 programs. Results showed that clients in the IPS program were more likely to be competitively employed throughout most of the 18-month follow-up. Among those who obtained jobs, there were few group differences, although workers in the IPS program did work more total hours and earn more total wages during the 18-month follow-up. There were no group differences on nonvocational outcomes.
