Mental health system funding of cognitive enhancement interventions for schizophrenia: summary and update of the New York Office of Mental Health expert panel and stakeholder meeting.

TOPIC: A growing research literature indicates that cognitive enhancement (CE) interventions for people with schizophrenia can improve cognitive functioning and may benefit psychosocial functioning (e.g., competitive employment, quality of social relationships). Debate continues regarding the strength of evidence for CE and related policy implications, such as the appropriateness of funding CE services. PURPOSE: This paper summarizes and updates a meeting of experts and stakeholders convened in 2008 by the New York Office of Mental Health to review evidence on the impact of CE for people with schizophrenia and other serious mental illnesses, and addresses whether the evidence base for CE interventions is sufficient to warrant funding. SOURCES USED: Specific recommendations based on the extant literature are provided regarding the structure and components of CE programs that should be present in order to improve cognitive and psychosocial outcomes and therefore merit consideration of funding. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: These recommendations may serve as a starting point in developing standards for CE programs. Establishing evidence-based practice standards for implementing CE interventions for people with serious mental illnesses may facilitate dissemination of programs that have the greatest potential for improving individuals' functional outcomes while minimizing incremental costs associated with providing CE services. Important open questions include how the performance of CE programs should be monitored and which individuals might be expected to benefit from CE as evidenced by improved functioning in their everyday lives.

Impact of Family History in Persons With Dual Diagnosis.

OBJECTIVE: This study examined relationships among family history of alcohol, drug, and psychiatric problems and substance use severity, interpersonal relationships, and service use in individuals with dual diagnosis. METHODS: Data were collected with the family history section of the Addiction Severity Index administered as part of three studies of individuals with dual disorders (N=413). Participants were categorized into family history risk groups for each problem domain based on the number of first and second degree relatives with alcohol, drug, or psychiatric problems. RESULTS: Rates of alcohol, drug, and psychiatric problems were high across family member categories and highest overall for siblings. Over two-thirds of the sample was categorized in the high-risk group in the alcohol problem domain, almost half of the sample was categorized as high-risk in the drug problem domain, and over a third of the sample was categorized as high-risk in the psychiatric problem domain. Across problem domains, individuals in the high-risk group reported more relationship problems with parents and siblings and higher rates of lifetime emotional, physical, and sexual abuse than did those in the low or moderate-risk groups. CONCLUSIONS: Family history of alcohol, drug, and psychiatric problems is associated with greater rates of poor family relationships and history of abuse. Assessment of these different forms of family history in multiple family members can aid treatment providers in identifying individuals with dual disorders who may benefit from trauma-informed care as part of their overall mental health and substance abuse treatment services.

Issues and developments on the consumer recovery construct.

The consumer recovery model has had increasing influence on mental health practices in the United States, Western Europe, and several other countries. However, adoption of the model has reflected political decisions rather than empirical evidence of the validity of the model or its value for treatment services. The recovery construct is poorly defined, and until recently there has been no reliable and valid measure with which to base a research program. We have developed an empirical measure that is well-suited for both research and clinical applications: the Maryland Assessment of Recovery in Serious Mental Ill-ness (MARS). We briefly describe the MARS and present preliminary data demonstrating that recovery is not a simple by-product of traditional outcome do-mains, but seems to be a distinct construct that may have important implications for understanding consumers with serious mental illness and for evaluating the outcome of treatment programs.

Patterns and Predictors of Changes in Substance Use in Individuals with Schizophrenia and Affective Disorders.

OBJECTIVE: This study examined patterns and predictors of changes in substance use over one year in individuals with schizophrenia and affective disorders. We examined patterns of cocaine use over time, baseline predictors of continued cocaine use over one year, and predictors of transitions into and out of drug use and treatment. METHODS: We recruited 240 individuals with schizophrenia and affective disorders who met DSM-IV criteria for current cocaine dependence or cocaine dependence in early full or sustained full remission, and assessed them five times over twelve months. RESULTS: There was no change over time in either the proportion of the sample with at least one day of cocaine use in the past month or in the average number of days of cocaine use among those who reported any use. Baseline variables tapping actual substance use were found to predict a decreased likelihood of cocaine use. Several variables tapping actual substance use - including self- reported use of cocaine, positive urinalysis for marijuana, and positive urinalysis for cocaine - were predictive of transitions into and out of outpatient substance abuse treatment. Readiness to change variables such as self-efficacy and temptation to use drugs showed different predictive patterns for the schizophrenia and affective disorder groups. CONCLUSIONS: These findings illustrate how drug use may show a cyclical pattern for those with serious mental illness, in which more severe use - characterized by greater frequency of use and associated problems - is followed by decreased use over time.

Assessing recovery of people with serious mental illness: development of a new scale.

OBJECTIVES: The authors describe the development of the Maryland Assessment of Recovery in People with Serious Mental Illness, or MARS, a 25-item self-report instrument that measures recovery of people with serious mental illness, and report a study of its psychometric properties. METHODS: Doctoral-level scientists with expertise in serious mental illness drafted a set of survey items about the recovery process. Items reflected recovery domains outlined by the Substance Abuse and Mental Health Services Administration. After consultation with a panel of experts on recovery that included consumers and clinical scientists and with a small group of consumers, the instrument was narrowed to 67 items and administered to 166 individuals recruited from outpatient mental health clinics in two states. Item response theory and classical item analysis were used to select best-fitting items, reduce item redundancy, and improve the psychometric properties of the scale. Principal components analysis and confirmatory factor analysis were conducted to further examine dimensions of recovery measured by the scale. RESULTS: The MARS is quite practical for use with individuals with serious mental illness. It demonstrated excellent internal consistency (Cronbach's α=.95) and test-retest reliability (r=.898) and good face and content validity. CONCLUSIONS: The data provide initial support for use of the MARS to measure recovery of people with serious mental illness.

Predictors of initiation and engagement in substance abuse treatment among individuals with co-occurring serious mental illness and substance use disorders.

Research has documented the significant challenges of engaging individuals with comorbid serious mental illness (SMI) and substance use disorders (SUDs) in substance abuse treatment. To date it is unclear which factors predict treatment initiation and engagement in this group of individuals with SUDs. In this study we conducted two analyses using data from a randomized trial of substance abuse treatment in outpatients with SMI: the first examining predictors (collected during screening) of completing an initial intake assessment and the second examining predictors (collected during the intake assessment) of becoming engaged in treatment. Results indicated that males and those with schizophrenia spectrum diagnoses were less likely to complete the intake assessment. Participants who reported more positive feelings about their family were more likely to engage in substance abuse treatment. Participants who were recently arrested were less likely to engage in treatment. Those who met criteria for current drug dependence were less likely to engage in treatment. Overall, these findings are a useful step in determining factors that predict substance abuse treatment initiation and engagement in individuals with SMI and SUDs.

The 2009 schizophrenia PORT psychosocial treatment recommendations and summary statements.

The Schizophrenia Patient Outcomes Research Team (PORT) psychosocial treatment recommendations provide a comprehensive summary of current evidence-based psychosocial treatment interventions for persons with schizophrenia. There have been 2 previous sets of psychosocial treatment recommendations (Lehman AF, Steinwachs DM. Translating research into practice: the Schizophrenia Patient Outcomes Research Team (PORT) treatment recommendations. Schizophr Bull. 1998;24:1-10 and Lehman AF, Kreyenbuhl J, Buchanan RW, et al. The Schizophrenia Patient Outcomes Research Team (PORT): updated treatment recommendations 2003. Schizophr Bull. 2004;30:193-217). This article reports the third set of PORT recommendations that includes updated reviews in 7 areas as well as adding 5 new areas of review. Members of the psychosocial Evidence Review Group conducted reviews of the literature in each intervention area and drafted the recommendation or summary statement with supporting discussion. A Psychosocial Advisory Committee was consulted in all aspects of the review, and an expert panel commented on draft recommendations and summary statements. Our review process produced 8 treatment recommendations in the following areas: assertive community treatment, supported employment, cognitive behavioral therapy, family-based services, token economy, skills training, psychosocial interventions for alcohol and substance use disorders, and psychosocial interventions for weight management. Reviews of treatments focused on medication adherence, cognitive remediation, psychosocial treatments for recent onset schizophrenia, and peer support and peer-delivered services indicated that none of these treatment areas yet have enough evidence to merit a treatment recommendation, though each is an emerging area of interest. This update of PORT psychosocial treatment recommendations underscores both the expansion of knowledge regarding psychosocial treatments for persons with schizophrenia at the same time as the limitations in their implementation in clinical practice settings.

A randomized, controlled trial of computer-assisted cognitive remediation for schizophrenia.

OBJECTIVE: There is considerable interest in cognitive remediation for schizophrenia, but its essential components are still unclear. The goal of the current study was to develop a broadly targeted computer-assisted cognitive remediation program and conduct a rigorous clinical trial in a large group of schizophrenia patients. METHOD: Sixty-nine people with schizophrenia or schizoaffective disorder were randomly assigned to 36 sessions of computer-assisted cognitive remediation or an active control condition. Remediation broadly targeted cognitive and everyday performance by providing supportive, graduated training and practice in selecting, executing, and monitoring cognitive operations. It used engaging computer-based cognitive exercises and one-on-one training. A total of 61 individuals (34 in remediation group, 27 in control group) engaged in treatment, completed posttreatment assessments, and were included in intent-to-treat analyses. Primary outcomes were remediation exercise metrics, neuropsychological composites (episodic memory, working memory, attention, executive functioning, and processing speed), and proxy measures of community functioning. RESULTS: Regression modeling indicated that performance on eight of 10 exercise metrics improved significantly more in the remediation condition than in the control condition. The mean effect size, favoring the remediation condition, was 0.53 across all 10 metrics. However, there were no significant benefits of cognitive remediation on any neuropsychological or functional outcome measure, either immediately after treatment or at the 3-month follow-up. CONCLUSIONS: Cognitive remediation for people with schizophrenia was effective in improving performance on computer exercises, but the benefits of training did not generalize to broader neuropsychological or functional outcome measures. The evidence for this treatment approach remains mixed.

Neurocognitive characteristics of individuals with schizophrenia and cocaine dependence: comparison of currently dependent and remitted groups.

Several investigations of cognitive functioning in individuals with schizophrenia and co-occurring cocaine use have yielded mixed results when compared with samples with schizophrenia only. However, no studies have specifically compared remitted and current cocaine dependence in schizophrenia. Such an analysis could help clarify the degree and type of cognitive impairment associated with cocaine dependence in schizophrenia. Two samples of individuals with schizophrenia - those with current cocaine dependence (n = 72) and those with cocaine dependence in remission (n = 48) were compared on a brief neuropsychological test battery. Parallel current dependent and remitted samples with affective disorder (n = 65 and n = 55) were also included in the analyses. Results yielded few neuropsychological differences between remitted and current dependent states across the SZ and AD groups. These findings suggest that cognitive impairment may be relatively static in these populations.

Substance dependence and remission in schizophrenia: A comparison of schizophrenia and affective disorders.

The present study examined psychiatric functioning, substance use and consequences, and motivation to change in people with schizophrenia and affective disorders and current or remitted cocaine dependence. Data were collected as part of a naturalistic, longitudinal study examining substance use, motivation to change, and the process of change in people with schizophrenia and affective disorders who were currently dependent or in remission from cocaine dependence. We examined the following questions: (1) Do those in remission show better psychiatric functioning than those who are currently dependent? (2) How do people with schizophrenia and current cocaine dependence differ in terms of substance use and consequences from people with schizophrenia in remission and people with affective disorders and current drug dependence? (3) What internal factors and external factors are associated with changes in substance use in schizophrenia and how do these compare to those in nonpsychotic affective disorders? Results indicated that people with schizophrenia and current dependence reported higher levels of positive and negative symptoms than those in remission. Remission status was related to less use of other drugs, fewer days of drug problems, less distress from drug problems, and more lifetime drug-related consequences. Those with current dependence reported more days of drinking and drinking to intoxication, as well as higher rates of current alcohol use disorders than the remitted group. When compared to those with affective disorders and cocaine dependence, those with schizophrenia and current dependence reported fewer days of problems associated with their drug use, less distress from drug problems, and fewer recent and lifetime consequences associated with their drug use. The schizophrenia dependent group generally showed the lowest readiness to change, fewest efforts being made to change, and lowest confidence in the ability to change. Implications of these findings are discussed.

Toward a terminology for functional recovery in schizophrenia: is functional remission a viable concept?

Recovery in schizophrenia is receiving increasing attention. Part of the increased focus is based on the recent working criteria for clinical remission in schizophrenia and the realization that many people with schizophrenia meet these criteria for remission. In this article, we consider whether functional disability can also be evaluated in a "remission" model. In so doing, we evaluate the concept of clinical remission, evaluate the possibility of remission of other generally stable features of schizophrenia such as negative symptoms, and make some heuristic terminological recommendations. We also propose a "level and breadth" model for the definition of functional remission and examine some of the alternate influences that could produce suboptimal everyday functioning, including effort, motivation, and societal barriers toward functional achievement.

Examination of the inventory of drug use consequences with individuals with serious and persistent mental illness and co-occurring substance use disorders.

BACKGROUND: The Inventory of Drug Use Consequences (InDUC) ( [1] ) is a 50-item measure that evaluates lifetime and recent consequences of substance use. OBJECTIVES: This study examined the psychometric properties of a modified version of the Inventory of Drug Use Consequences (InDUC-M) in individuals with serious and persistent mental illness (SPMI) and co-occurring substance use disorders (SUDs). METHODS: We examined self-reported consequences in the sample, evaluated internal consistency, identified items for a brief form of the InDUC-M, and explored relationships with indicators of substance use severity. RESULTS: InDUC-M Lifetime and Recent subscales showed good internal consistency and were related to other measures of substance use and problems. A brief version of the InDUC-M Recent (SIP-M) showed excellent internal consistency and was highly correlated with both Lifetime and Recent subscales. CONCLUSION: The InDUC-M and the SIP-M performed well in individuals with SPMI and SUDs. CONCLUSION AND SCIENTIFIC SIGNIFICANCE: Overall, these findings are a useful first step in determining the utility of the InDUC-M in people with SPMI and SUDs.

Application of the Transtheoretical Model of change: psychometric properties of leading measures in patients with co-occurring drug abuse and severe mental illness.

People with severe mental illness (SMI) have high rates of substance use disorders. The Transtheoretical Model (TTM) is a framework for understanding behavior change. There are five leading measures associated with the TTM - University of Rhode Island Change Assessment, Processes of Change Scale, Decisional Balance Scale, Abstinence Self-Efficacy Scale, and Temptation to Use Drugs Scale. While these measures have been found to be reliable and valid in primary substance abusers, it is unknown if these measures are relevant in people with co-occurring SMI and substance use disorders (SUD). We evaluated the psychometric properties of these measures in a sample (n=240) of people with co-occurring disorders. Participants met DSM-IV criteria for schizophrenia/schizoaffective disorder or non-psychotic affective disorder, and current cocaine dependence or cocaine dependence in remission. All subscales showed good reliability and validity in the total sample. Analyses within diagnostic groups showed good reliability and validity in most groups, with some falling off in the affective disorders and remitted cocaine dependence groups. Overall, findings support the use of these measures in people with co-occurring disorders.

A scientific agenda for the concept of recovery as it applies to schizophrenia.

Recovery is now a widely discussed concept in the field of research, treatment, and public policy regarding schizophrenia. As it has increasingly become a focus in mainstream psychiatry, however, it has also become clear both that the concept is often used in multiple ways, and that it lacks a strong scientific basis. In this review, we argue that such a scientific basis is necessary for the concept of recovery to have a significant long-term impact on the way that schizophrenia is understood and treated. The discussion focuses on key issues necessary to establish this scientific agenda, including: 1) differences in definitions of recovery and their implications for studying recovery processes and outcomes; 2) key research questions; 3) the implications of data from outcome studies for understanding what is possible for people diagnosed with schizophrenia; 4) factors that facilitate recovery processes and outcomes, and methods for studying these issues; and 5) recovery-oriented treatment, including issues raised by peer support. Additional conceptual issues that have not received sufficient attention in the literature are then noted, including the role of evidence-based practices in recovery-oriented care, recovery-oriented care for elderly people with schizophrenia, trauma treatment and trauma-informed care, and the role of hospitals in recovery-oriented treatment. Consideration of these issues may help to organize approaches to the study of recovery, and in doing so, improve the impact of recovery-based initiatives.

Motivation and the stages of change among individuals with severe mental illness and substance abuse disorders.

A complicating factor affecting the treatment of individuals with coexisting substance use problems and serious mental illness is their motivation for change and how these interacting, chronic conditions affect the entire process of intentional behavior change. This selective review explores conceptual and assessment issues related to readiness to modify substance use and readiness to initiate behaviors helpful for managing mental illness in the search for a better understanding of patient motivation for change. The recent but limited research on motivation and stages of change among dually diagnosed patients indicates that these individuals appear to access and use an intentional behavior change process. However, it is not completely clear how this process works and what precise adaptations are needed to assess and to access motivation to change to encourage sustained behavior change in this population. Nevertheless, motivation and readiness to change are important dimensions that need to be addressed in treatment and research with dually diagnosed populations.

Is learning potential associated with social skills in schizophrenia?

Cognitive deficits are a primary factor in the social and functional impairments characteristic of schizophrenia and an important predictor of treatment success in psychosocial rehabilitation. This study examined the association between abstract reasoning and social functioning by assessing whether learning potential on the Wisconsin Card Sorting Test (WCST) relates to changes in social competence following social skills training (SST). Fifty-six veterans with schizophrenia or schizoaffective disorder completed a series of assessments followed by eight SST sessions. To evaluate learning potential, we assessed participants with the WCST and Category Test (CT), taught them a training protocol for the WCST, and retested on both measures. Participants learned the WCST, generalized this learning to improve their performance on the CT, and retained these gains for several weeks. Participants showed small improvements on the Maryland Assessment of Social Competence (MASC), but WCST learning potential and CT generalization were unrelated to improvement on the MASC.

Performance-based measures of functional skills: usefulness in clinical treatment studies.

Recently, attention to the assessment and treatment of functional disability has increased notably. It is widely understood that impairments in everyday living skills, including independent living skills, social functions, vocational functioning, and self-care, are present in people with schizophrenia. It has also become clear recently that assessment of these skills can pose substantial challenges. These challenges include selection of meaningful short-term outcome measures and avoiding bias and reduced validity in the data. Self-report, direct observation, and informant reports of everyday disability all have certain advantages but appear to be inferior to direct assessment of skills with performance-based measures. This review outlines the issues associated with the assessment of functional skills and everyday functioning and provides a description of the strengths and weaknesses of these approaches. We conclude that direct assessment of functional capacity has substantial advantages over other measures and may actually provide a more direct and valid estimate of functional disability than performance on the more distal neuropsychological assessment measures.

Assessment of motivation to change substance use in dually-diagnosed schizophrenia patients.

Assessment of motivation to change substance use can be helpful in evaluating treatment readiness and outcome. However, the utility of self-report measures of motivation with schizophrenia patients is questionable. In the current study patients with schizophrenia and either concurrent cocaine dependence or remitted dependence completed the University of Rhode Island Change Assessment-Maryland (URICA-M), a self-report inventory that assesses motivation, and an analogous cartoon instrument at baseline and 6-months follow-up. Results demonstrate that the cartoon readiness to change score was related to increased treatment utilization and decreased substance use; results were not as favorable for the URICA-M. Findings suggest that the cartoon measure may be a suitable alternative to assess motivation to change substance use with cognitively impaired patients.
