Examining the research base for child mental health services and policy

This article reviews the existing research base for child mental health services and policy. It emphasizes the importance of research that looks at the overall community-based system of care as the unit of analysis, and stresses the need to maintain a systems perspective, even when research is focused on components of the overall system. The review concludes that there is a need for a considerable increase in child mental health services research but also indicates that there has been a recent increase in research that has the potential of building a base to change policy. In particular, a need is identified for well-controlled studies that assess both clinical and cost outcomes and for studies that examine the mega issues of the organization and financing of systems of care.

Use, persistence, and intensity: patterns of care for children's mental health across one year

This paper explores the use, persistence, and intensity of services for children's mental health problems across a variety of service sectors during a one year period. Data come from the Great Smoky Mountains Study. Analyses focus on children's psychiatric symptomatology and impairment, service use, and factors that may influence the relationship between psychiatric problems and service use across a one year period. Findings show that approximately 20% of children used some mental health services from some sector during the year. Child's symptomatology and characteristics of parents were associated with use and persistence of services. Parent's perceptions of impact on the family were associated with service use, persistence, and intensity.

Impaired but undiagnosed

OBJECTIVE

To investigate the prevalence and outcomes of individuals with psychosocial impairment not meeting DSM-III-R criteria for any of 29 well-defined disorders and to suggest operational definitions for not otherwise specified (NOS) diagnoses and V codes.

METHODS

Two-stage general population sampling resulted in 1,015 youths aged 9, 11, and 13 years being interviewed in the first wave of the Great Smoky Mountains Study. They were reinterviewed 1 year later using the Child and Adolescent Psychiatric Assessment.

RESULTS

The weighted prevalence of sibling relational problems was found to be 1.4%. That of parent-child relational problems was 3.6% and that of relational problems NOS was 0.6%. The overall rate of symptomatic impairment was 9.4%. Across a variety of "caseness measures," those with symptomatic impairment proved to be more disturbed than those without either a diagnosis or impairment, and as disturbed as those with a diagnosis but without impairment.

CONCLUSION

Children and adolescents who do not meet DSM-III-R criteria for any well-defined disorder but who have symptoms associated with psychosocial impairment should be regarded as suffering from a psychiatric disorder. It is suggested that researchers adopt this definition for the many NOS diagnoses included in the DSM nosology and implement it in their research diagnostic algorithms.

Taking the wrong drugs: the role of substance abuse and medication noncompliance in violence among severely mentally ill individuals

Increasing numbers of severely mentally ill individuals are being treated in nonhospital, community-based settings and public concern about potential violence by these individuals has increased, often as a result of tragic, albeit uncommon events. The present study examines potential predictors of serious violence among persons with severe mental illness (SMI), with a specific focus on the joint effect of substance abuse and medication noncompliance. Subjects in the study are involuntarily admitted inpatients with SMI awaiting a period of court-ordered outpatient treatment, termed "involuntary outpatient commitment". During enrollment in a longitudinal outcome study of the effectiveness of OPC, 331 subjects and, whenever feasible, family members or other informants were interviewed. In addition, complementary data were gathered by review of involuntary commitment records and hospital records. Data collection included sociodemographic characteristics, illness history, clinical status, medication adherence, substance abuse and violent behavior during the 4 months preceding hospitalization. Descriptive and multivariable logistic regression procedures were used to examine the association between serious violent acts and a number of personal, social, and clinical characteristics. The combination of medication noncompliance and substance abuse was a significant predictor of serious violent acts in the community. Individuals who had problems with both alcohol and illicit drug abuse appear to be at greatest risk for violence. These results suggest that reducing violence risk among persons with SMI requires an aggressive approach to improving medication adherence in the context of integrated mental health and substance abuse treatment.

Administrative update: utilization of services. I. Comparing use of public and private mental health services: the enduring barriers of race and age

Data from the NIMH-Epidemiologic Catchment Area Project were used to predict differential use of private versus public outpatient mental health services, a salient concern in integrating public and private services in market-based health care reform efforts. Having a recent psychiatric disorder, being age 25-44, female, white, of higher educational level, and unmarried increase the odds of any mental health service use. However, odds of treatment in the public sector are increased for males, African Americans, those with low educational and income levels, and odds are markedly decreased for the elderly, suggesting significant barriers to care for these mentally ill subpopulations.

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.

Outpatient utilization patterns of integrated and split psychotherapy and pharmacotherapy for depression

OBJECTIVE

This exploratory study examined utilization and costs among depressed patients in two treatment models-integrated treatment, in which psychotherapy and pharmacotherapy were provided by a psychiatrist, and split treatment, in which pharmacotherapy was provided by a psychiatrist and psychotherapy by a nonphysician psychotherapist.

METHODS

A quasi-experimental retrospective design was used to compare claims data from a national managed mental health care organization for 191 patients in integrated treatment and 1,326 in split treatment.

RESULTS

During the 18-month study, patients receiving integrated treatment used significantly fewer outpatient sessions and had significantly lower treatment costs, on average, than those in split treatment. Integrated treatment appeared to be associated with a pattern of utilization characterized by frequent treatment episodes in contrast to that of split treatment, which was characterized by more sessions with fewer breaks of 90 days or more.

CONCLUSIONS

The results do not support the prevailing assumption that integrated treatment is more costly than split treatment in a managed care network. Despite limitations in the study methods, the strength of these preliminary findings poses a powerful challenge and invites further study.

Violence and severe mental illness: the effects of substance abuse and nonadherence to medication

OBJECTIVE

Violent behavior among individuals with severe mental illness has become an important focus in community-based care. This study examines the joint effect of substance abuse and medication noncompliance on the greater risk of serious violence among persons with severe mental illness.

METHOD

Involuntarily admitted inpatients with severe mental illness who were awaiting a period of outpatient commitment were enrolled in a longitudinal outcome study. At baseline, 331 subjects underwent an extensive face-to-face interview. Complementary data were gathered by a review of hospital records and a telephone interview with a family member or other informant. These data included subjects' sociodemographic characteristics, illness history, clinical status, medication adherence, substance abuse, insight into illness, and violent behavior during the 4 months that preceded hospitalization. Associations between serious violent acts and a range of individual characteristics and problems were analyzed by using multivariable logistic regression.

RESULTS

The combination of medication noncompliance and alcohol or substance abuse problems was significantly associated with serious violent acts in the community, after sociodemographic and clinical characteristics were controlled.

CONCLUSIONS

Alcohol or other drug abuse problems combined with poor adherence to medication may signal a higher risk of violent behavior among persons with severe mental illness. Reduction of such risk may require carefully targeted community interventions, including integrated mental health and substance abuse treatment.

Perceived parental burden and service use for child and adolescent psychiatric disorders

OBJECTIVES

Pediatric chronic physical illness and adult psychiatric disorders are substantial sources of burden for family care-takers, but little attention has been paid to parental burden resulting from children's or adolescents' psychiatric disorders. This paper describes the predictors of perceived parental burden and its impact on the use of specialty mental health and school services.

METHODS

A representative general population sample of 1015 9-, 11-, and 13-year-olds and their parents completed structured psychiatric diagnostic interviews and the Child and Adolescent Burden Assessment.

RESULTS

Weighted estimates indicated that 10.7% of parents in the general population perceived burden resulting from their children's symptomatology. Significant predictors of perceived burden were levels of child symptomatology and impairment and parental mental health problems. Children's depressive and anxiety disorders were associated with less burden than other diagnoses. The effects of child disorder severity on specialty mental health service use appeared to be mediated by the level of burden induced.

CONCLUSIONS

Substantial levels of parental burden resulted from child psychiatric disorders and were a major reason for specialist mental health service use.

Psychiatric disorders among American Indian and white youth in Appalachia: the Great Smoky Mountains Study

OBJECTIVES

This study examined prevalence of psychiatric disorders, social and family risk factors for disorders, and met and unmet needs for mental health care among Appalachian youth.

METHODS

All 9-, 11-, and 13-year-old American Indian children in an 11-county area of the southern Appalachians were recruited, together with a representative sample of the surrounding population of White children.

RESULTS

Three-month prevalences of psychiatric disorders were similar (American Indian, 16.7%; White, 19.2%). Substance use was more common in American Indian children (9.0% vs 3.8% in White children), as was comorbidity of substance use and psychiatric disorder (2.5% vs 0.9%). American Indian poverty, family adversity (e.g., parental unemployment, welfare dependency), and family deviance (parental violence, substance abuse, and crime) rates were higher, but the rate of family mental illness, excluding substance abuse, was lower. Child psychiatric disorder and mental health service use were associated with family mental illness in both ethnic groups but were associated with poverty and family deviance only in White children. Despite lower financial barriers, American Indian children used fewer mental health services.

CONCLUSIONS

This study suggests that poverty and crime play different roles in different communities in the etiology of child psychiatric disorder.

Assessing the effectiveness of mental health care in routine clinical practice. Characteristics, development, and uses of patient outcomes modules

The health care delivery system faces continually increasing pressure to be accountable for the historically unparalleled amount of resources it utilizes. This article discusses one set of recently developed tools known as outcomes modules that are used to assess how treatment affects outcomes in patients with a given disorder. These tools currently are being used to inform administrative decisions about how to improve the quality of care, and can potentially influence decisions by patients, providers, and payers of care as well. The critical components of outcomes modules, as well as their administration and applications are described, using modules for psychiatric conditions as examples.

Interpreting the effectiveness of involuntary outpatient commitment: a conceptual model

Many experimental trials of community mental health interventions fail to develop testable conceptual models of the specific mechanisms and pathways by which relevant outcomes may occur, thus falling short of usefully interpreting what happens inside the experimental "black box." This paper describes a conceptual model of involuntary outpatient commitment (OPC) for persons with severe and persistent mental disorders. The model represents an attempt to "unpack" the effects of OPC by incorporating several interacting variables at various stages. According to this model, court-mandated outpatient treatment may improve long-term outcomes both directly and indirectly in several ways: by stimulating case management efforts, mobilizing supportive resources, improving individual compliance with treatment in the community, reducing clients' psychiatric symptoms and dangerous behavior, improving clients' social functioning, and finally by reducing the chance of illness relapse and rehospitalization. A randomized clinical trial of OPC is underway in North Carolina that will test the direct and indirect effects suggested by this model, using longitudinal data from the multiple perspectives of mental health clients, family members, and case managers.

The ethical challenges of a randomized controlled trial of involuntary outpatient commitment

Involuntary outpatient commitment (OPC) is a civil justice procedure intended to enhance compliance with community mental health treatment, to improve functioning, and to reduce recurrent dangerousness and hospital recidivism. The research literature on OPC indicates that it appears to improve outcomes in rates of rehospitalization and length of stay. However, all studies to date have serious methodological limitations because of selection bias; lack of specification of target populations; unclear operationalization of OPC; unmeasured variability in type, frequency, and intensity of treatment; as well as other confounding factors. To address limitations in these studies, the authors designed a randomized controlled trial (RCT) of OPC, combined with community-based case management, which is now under way in North Carolina. This article describes ethical dilemmas in designing and implementing an RCT of a legally coercive intervention in community-based settings. These ethical dilemmas challenge the experimental validity of an RCT but can be successfully addressed with careful planning and negotiation.

The Great Smoky Mountains Study of Youth. Goals, design, methods, and the prevalence of DSM-III-R disorders

BACKGROUND

The Great Smoky Mountains Study of youth focuses on the relationship between the development of psychiatric disorder and the need for and use of mental health services.

METHODS

A multistage, overlapping cohorts design was used, in which 4500 of the 11758 children aged 9, 11, and 13 years in an 11-county area of the southeastern United States were randomly selected for screening for psychiatric symptoms. Children who scored in the top 25% on the screening questionnaire, together with a 1 in 10 random sample of the rest, were recruited for 4 waves of intensive, annual interviews (n = 1015 at wave 1). In a parallel study, all American Indian children aged 9, 11, and 13 years were recruited (N = 323 at wave 1).

RESULTS

The 3-month prevalence (+/-SE) of any DSM-III-R axis I disorder in the main sample, weighted to reflect population prevalence rates, was 20.3% +/- 1.7%. The most common diagnoses were anxiety disorders (5.7% +/- 1.0%), enuresis (5.1% +/- 1.0%), tic disorders (4.2% +/- 0.9%), conduct disorder (3.3% +/- 0.6%), oppositional defiant disorder (2.7% +/- 0.4%), and hyperactivity (1.9% +/- 0.4%).

CONCLUSIONS

The prevalence of psychiatric disorder in this rural sample was similar to rates reported in other recent studies. Poverty was the strongest demographic correlate of diagnosis, in both urban and rural children.

The Great Smoky Mountains Study of Youth. Functional impairment and serious emotional disturbance

BACKGROUND

Federal regulations require states to estimate the prevalence and incidence of serious emotional disturbance (SED) in children, defined as a DSM-III-R diagnosis in the presence of impaired functioning in 1 or more areas. We reviewed the published data on SED and examined rates and correlates of SED in an ongoing epidemiologic study of children.

METHODS

Rates of DSM-III-R disorders, functional impairment, and their co-occurrence (SED) were examined in a representative population sample of 9-, 11-, and 13-year-olds from a predominantly rural area of North Carolina. Three measures of functional impairment were used, and their interrelationship and impact on rates of SED were examined.

RESULTS

Serious emotional disturbance was identified in 4% to 8% of the study population, depending on the measure of impairment; the rate of DSM-III-R disorder ignoring impairment was 20.3%. One quarter of children identified as having SED on any measure were identified by all 3, and one half by 2 or more. Behavioral disorders, emotional disorders, and comorbidity were associated with a significant increase in the likelihood of SED; enuresis and tic disorders in the absence of comorbidity were not. Diagnosis and impairment made independent contributions to the increase in service use seen in children with SED. Poverty greatly increased the likelihood of SED.

CONCLUSIONS

Specific areas of functional impairment should be examined when SED is assessed and treatment is planned. Plans to target mental health care resources to children with SED need to be accompanied by efforts to ensure access to those resources.

Outcomes of mental health care for children and adolescents: I. A comprehensive conceptual model

OBJECTIVE

Accountability for mental health care has become a standard of clinical practice. With the expansion of managed care as a corporate response to health reform, attention to outcomes will intensity. Assessment of clinical treatment has typically focused on symptom reduction at an individual level, whereas assessment of service effectiveness has more often targeted service-level change.

METHOD

A dynamic and interactional model of outcomes is presented that broadens the range of intended consequences of care. The model comprises five domains: symptoms, functioning, consumer perspectives, environmental contexts, and systems.

RESULTS

The model reflects the changeable interaction between children's evolving capacities and their primary environments (home, school, and community).

CONCLUSIONS

As health care practices shift, attention to improved care is likely to depend increasingly on scientifically credible evidence of its impact. Greater integration between research and standard practice will be needed. Such a partnership can be strengthened by a more comprehensive view of the impact of care.

What drives outcomes for emotional and behavioral disorders in children and adolescents?

The outcomes of child and adolescent disorders are multiply determined, and the range of factors influencing them requires full attention as the benefits of mental health services are assessed.

Research on field-based services: models for reform in the delivery of mental health care to populations with complex clinical problems

OBJECTIVE

Clinical services for psychiatrically impaired populations have only recently been studied with scientifically valid designs to explore innovations in structure, accessibility, and financing. Health systems reform in the United States has provided the impetus for better defining clinically effective and cost-sensitive models for mental health services. This article reviews assertive community treatment, used for adults with severe mental illnesses, and multisystemic therapy, used for adolescents with serious emotional disturbances, as examples of service system innovations that have been studied with controlled clinical trial designs and have demonstrated efficacy in treating difficult and costly clinical populations.

METHOD

The authors reviewed the published controlled clinical trials of assertive community treatment and multisystemic therapy, focusing on the clinical and administrative elements that distinguish them from traditional service systems.

RESULTS

A qualitative assessment of these two approaches suggests that they share common elements, with important implications for mental health policy. Specifically, the use of an ecological model of behavior applied to mental health patients is critical to both systems. In addition, therapeutic principles emphasizing pragmatic (outcome-oriented) treatment approaches, home-based interventions, and individualized goals are key elements of their success. Most important, both systems embody a therapeutic philosophy demanding therapist accountability, in which personnel are rewarded for clinical outcomes and therapeutic innovation rather than for following a prescribed plan.

CONCLUSIONS

As empirically tested approaches, assertive community treatment and multisystemic therapy provide a scientific foundation for continued reform and serve to illustrate critical elements in designing new community treatment initiatives for behavioral as well as medical conditions.

Assertive community treatment: an update of randomized trials

OBJECTIVE

Results of randomized clinical trials of assertive community treatment for seriously mentally ill patients published between 1990 and 1994 are reviewed to synthesize the state of knowledge about this research and to clarify continuing research directions.

METHODS

Randomized trials of interventions that used treatment principles and practices consistent with the Program for Assertive Community Treatment model or close adaptations whose results were published since 1990 were identified by literature searches using MEDLINE and PsychLit and by contact with investigators of ongoing trials.

RESULTS

Controlled clinical trials have been conducted with a wide range of severely mentally ill populations, including patients in Great Britain, patients with recent-onset schizophrenia, veterans, dually diagnosed clients, and homeless persons. Methodological improvements in some studies include increased attention to monitoring the experimental and comparison interventions, as well as larger sample sizes and longer duration of the clinical trials than in earlier efficacy trials. Strong positive effects of assertive community treatment on hospital days and on patient and family satisfaction were found. Gains in functional outcomes, such as employment, may require interventions specifically targeted to these outcomes.

CONCLUSIONS

Questions about the role of assertive community treatment as time-limited treatment, as an adjunct to other services and treatment, or as a comprehensive and continuous service system for adults with severe mental illness require further research. The growing research base should provide valuable information on costs, outcomes, and indications for assertive community treatment that can be evaluated by policy-makers.

New directions in research on involuntary outpatient commitment

OBJECTIVE

Involuntary outpatient commitment has been used as a method of improving tenure in community programs for individuals with severe and persistent mental illness. This paper reviews literature on research about involuntary outpatient commitment and suggests questions and methods for future research.

METHODS

Literature describing research studies of involuntary outpatient commitment, located by searching MEDLINE and following up references cited in relevant articles, was reviewed with attention to patient characteristics and diagnostic, treatment, and outcomes measures.

RESULTS

Involuntary outpatient commitment appears to provide limited but improved outcomes in rates of rehospitalization and lengths of hospital stay. Variability in community treatment makes interpretation of other types of outcome difficult. Few studies specifically identify results among patients with severe and persistent mental illness.

CONCLUSIONS

No studies have examined the extent to which outpatient commitment affects compliance and treatment when essential community services such as case management are consistently and aggressively provided, nor have studies controlled for potentially confounding factors such as treatment and nontreatment effects, including informal coercion. A randomized trial of involuntary outpatient commitment should be useful in evaluating the effectiveness of this type of intervention.

Children's mental health service use across service sectors

This DataWatch explores the roles of human service sectors (mental health, education, health, child welfare, and juvenile justice) in providing mental health services for children. The data are from the first wave of the Great Smoky Mountains Study of Youth, a population-based study of psychopathology and mental health service use among children. The results show somewhat higher rates of mental health service use than has been reported previously, while continuing to show a substantial amount of unmet need, even among children with both a psychiatric diagnosis and functional impairment. The findings point to a significant role for the education sector, suggesting that schools may function as the de facto mental health system for children and adolescents.

The relationship between insurance coverage and psychiatric disorder in predicting use of mental health services

OBJECTIVE

This study investigated how insurance coverage for mental health services affects outpatient mental health service utilization among those with and among those without a DSM-III psychiatric diagnosis. The authors used a representative community sample to compare the regression effects of insurance coverage on utilization of mental health services among these subjects.

METHOD

Data are from the second wave of the Piedmont, North Carolina, site of the Epidemiologic Catchment Area project. These data contain DSM-III diagnostic measures derived from the National Institute of Mental Health Diagnostic Interview Schedule as well as measures of insurance coverage and utilization. Responses from 2,889 community residents were analyzed using both ordinary least squares and logistic regression.

RESULTS

In both models, insurance coverage was strongly associated with care among those with as well as among those without a psychiatric disorder. The association between coverage and the probability of care was strongest among those with a disorder.

CONCLUSIONS

The findings are not consistent with the claim that failing to provide insurance coverage will reduce discretionary but not necessary mental health care utilization. They provide evidence that failing to provide insurance coverage will reduce utilization as much or more among those with a psychiatric disorder as among those without. This result has important implications for health care reform.
