DeTore NR, Mueser KT, McGurk SR. What does the Managing Emotions branch of the MSCEIT add to the MATRICS consensus cognitive battery? Schizophr Res 2018; 197:414-420. [PMID: 29486955 DOI: 10.1016/j.schres.2018.02.018] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2017] [Revised: 12/15/2017] [Accepted: 02/15/2018] [Indexed: 10/18/2022]
Abstract
The Managing Emotions branch of the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT-ME) was included within the MATRICS Consensus Cognitive Battery (MCCB) as the measure of social cognition, although limited research has examined its associations with psychosocial functioning in people with schizophrenia or other severe mental illnesses. This secondary analysis with 107 participants examined what the MSCEIT-ME contributes to our understanding of functioning in this population, and whether it uniquely predicts psychosocial functioning after controlling for performance on the other MCCB tests and negative symptoms. Performance on the MSCEIT-ME was significantly correlated with all three MCCP factors (processing speed, attention/working memory, learning) within schizophrenia-schizoaffective disorder, bipolar disorder, and other mixed diagnoses groups. Better performance on MSCEIT-ME was associated with better psychosocial functioning on the Quality of Life Scale (QLS) in the schizophrenia-schizoaffective disorder group, but not in the bipolar or other mixed diagnoses groups. In addition, in the schizophrenia-schizoaffective disorder group, after controlling for demographic characteristics in stepwise multiple regression analyses, MSCEIT-ME was the only significant predictor of the QLS total score and the QLS interpersonal relations and intrapsychic foundations subscales, with none of the MCCB factors entering any of the regression models. The MSCEIT-ME may reflect a unique aspect of social cognition that is related to impaired psychosocial functioning in schizophrenia and is not tapped by the other cognitive tests on the MCCB. Further research on the MSCEIT-ME could provide unique insights into the social functioning problems in schizophrenia.

Abstract
OBJECTIVE This study examined job endings and work trajectories among participants in a study comparing the effects of adding cognitive remediation to supported employment among individuals who had not benefited from supported employment. METHODS Data were from a controlled trial of 107 persons with serious mental illness enrolled in supported employment but who had not obtained or sustained competitive work. Participants were randomly assigned to enhanced supported employment only (with employment specialists trained to recognize cognitive difficulties and teach coping strategies) or to the Thinking Skills for Work program (enhanced supported employment plus cognitive remediation). For the 52 participants who worked, the two groups were compared on types of job endings, reasons for job endings, successful versus unsuccessful jobs, and work trajectories over the two-year study period. RESULTS The two groups did not differ in types of job ending, although participants in Thinking Skills for Work were less likely than those in enhanced supported employment only to cite dissatisfaction with the job as a reason for the job ending. Participants in Thinking Skills for Work were also less likely to have an overall unsuccessful work trajectory, more likely to have only successful jobs, and more likely to be employed at the end of the study. CONCLUSIONS The Thinking Skills for Work program appeared to help participants who had not benefited from supported employment stick with and master their jobs more effectively than those in enhanced supported employment only, resulting in better work trajectories over the course of the study.

Abstract
BACKGROUND Impaired cognitive functioning is a significant predictor of work dysfunction in schizophrenia. Less is known, however about relationships of cognition and work in people with less severe disorders with relatively normal cognitive functioning. METHODS This secondary analysis evaluated cognitive predictors of work in Social Security Disability Insurance (SSDI) beneficiaries with a recent work history who were randomized to receive mental health services, supported employment, and freedom from work disincentives over a 2-year study period in the Mental Health Treatment Study. Of the 1045 participants randomized to the treatment package, 945 (90.4%) received a cognitive assessment at study entry. Competitive work activity was evaluated using a computer-assisted timeline follow-back calendar at baseline and quarterly for 24 months. RESULTS Mood disorders were the most common psychiatric diagnoses (64.9%), followed by schizophrenia or schizoaffective disorder (35.1%). Tobit regression analyses predicting the average number of hours worked per week, controlling for demographic characteristics, diagnosis, and work history indicated that the cognitive composite score (P < .01) and verbal learning subscale scores (P < .001) were associated with fewer hours of weekly work over the study period. CONCLUSIONS Cognitive functioning predicted work over 2 years in SSDI beneficiaries with mood or schizophrenia-spectrum disorders who were receiving supported employment and mental health interventions, despite a relative absence of cognitive impairment in the study participants. The findings suggest cognitive functioning contributes to competitive work outcomes in persons with psychiatric disorders who have relatively unimpaired cognitive abilities, even under optimal conditions of treatment and vocational support.

Abstract
This study examined whether cognitive functioning was related to treatment outcomes in persons with severe mental illness who received a cognitive behavioral therapy (CBT) program for co-occurring posttraumatic stress disorder (PTSD). The study sample was drawn from a larger controlled trial of 108 persons with severe mental illness and PTSD comparing the effects of CBT with treatment as usual on PTSD and related outcomes, with assessments conducted at baseline, post-treatment, and 3- and 6-month follow-ups. Among the 54 persons in CBT, 49 were administered a neuropsychological battery at baseline and 40 were exposed to the CBT program. Statistical analyses of these 40 participants were conducted to evaluate whether cognitive functioning was related to participation in the CBT program, completion of homework assignments, and improvements in PTSD, and other outcomes. Cognitive functioning was not related to participation in CBT or completion of homework. Lower cognitive functioning predicted less learning of information about PTSD at post-treatment and follow-up, but not less clinical benefit from CBT in PTSD diagnosis or symptoms, other symptoms, or health. The results suggest that cognitive impairment does not attenuate response to the CBT for PTSD program in persons with severe mental illness. Clinical Trials.gov Identifier: NCT00053690.

Abstract
BACKGROUND This study aims to examine the effects of change in neurocognition on functional outcomes and to examine predictors of change in social functions following a 12-week course of cognitive remediation in patients with schizophrenia and schizoaffective disorder with severe cognitive impairments. METHOD Level of social functioning was assessed using a performance based measure of functional capacity (PSP) in patients prior to and after the completion of 12-week cognitive remediation treatment (CRT). Participants completed a neuropsychological battery (MCCB-MATRICS) and clinical measures at both time points. RESULTS 63 subjects with a mean age of 41.4 (SD=12.2) and with 12.2years of education (SD=2.4) were enrolled. There were significant improvements in overall PSP score from baseline to endpoint (p=0.021) as well as in PSP domain A (socially useful activities) (p≤0.001), domain B (personal and social relationships) (p=0.009), and domain D (disturbing and aggressive behaviors) (p=0.003). There was a significant improvement in the composite MCCB score (p=0.020) and the Working Memory (p<0.046). Stepwise logistic regression yielded a significant association for baseline Visual Learning (Wald=6.537, p=0.011, OR=1.195), Speed of Processing (Wald=4.112, p=0.043, OR=0.850) and level of PANSS positive symptoms (Wald=4.087, p=0.043, OR=0.739) with PSP overall improvement. CONCLUSIONS Faster speed of processing, better visual and verbal learning and less prominent positive symptoms were associated with greater functional improvement after a systematic cognitive intervention within a rehabilitative setting.

Abstract
OBJECTIVE Adding cognitive remediation to vocational rehabilitation services improves cognitive and work functioning in people with serious mental illness, but despite interest, the uptake of cognitive programs into community services has been slow. This study evaluated the feasibility of implementing an empirically supported cognitive remediation program in routine rehabilitation services at 2 sites. METHOD The Thinking Skills for Work (TSW) program was adapted for implementation at 2 sites of a large psychiatric rehabilitation agency providing prevocational services, but not community-based vocational services, which were provided off-site. Agency staff were trained to deliver TSW to clients with work or educational goals. Cognitive assessments were conducted at baseline and posttreatment, with work and school activity tracked for 2 years. RESULTS Eighty-three participants enrolled in TSW, of whom 79.5% completed at least 6 of the 24 computer cognitive exercise sessions (M = 16.7) over an average of 18 weeks. Participants improved significantly from baseline to posttreatment in verbal learning and memory, speed of processing, and overall cognitive functioning. Over the follow-up, 25.3% of participants worked and 47.0% were involved in work or school activity. Higher work rates were observed at the site where participants had easier access to vocational services. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE The results support the feasibility of implementing the TSW program by frontline staff in agencies providing psychiatric rehabilitation, and suggest that ease of access to vocational services may influence work outcomes.

Abstract
OBJECTIVE Cognitive challenges are prominent features of individuals diagnosed with schizophrenia, impairing occupational, social, and economic functioning. These challenges are predictive of social and work outcomes. Cognitive remediation has been shown to be effective in improving both cognitive and social functions. However, cognitive remediation does not produce improvement in all participants. We investigated demographic, neurocognitive, and psychopathological predictors associated with improvement following cognitive remediation interventions in service recipients with severe mental illnesses. METHOD One hundred thirty-seven adult participants with a diagnosis of schizophrenia, schizoaffective disorder, or bipolar disorder according to the Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.) were enrolled in 12-week cognitive remediation programs. Assessments of demographic and illness variables, together with baseline and end point assessment of psychopathology (Positive and Negative Syndrome Scale [PANSS]), neurocognition (Measurement and Treatment Research to Improve Cognition in Schizophrenia [MATRICS] Consensus Cognitive Battery [MCBB]), and social functions (Personal and Social Performance Scale [PSP]) were conducted. Change in cognitive domains was calculated using the reliable change index. Logistic regression analysis was used to assess predictors of cognitive improvement after the intervention. RESULTS Sixty-two percent of participants improved on at least 1 of the MCCB domains. Higher baseline speed of processing, attention or vigilance, and working memory predicted a positive response to cognitive remediation. Younger age, higher education level, shorter length of stay, and lower PANSS Negative and Disorganized factors were additional predictors. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE Our results indicate the clinical usefulness of cognitive remediation and identified a pattern of clinical and cognitive predictors of good response to the intervention. Identification of these predictive factors by clinicians may enhance the outcome and aid in the development of individualized rehabilitative cognitive remediation treatment plans.

Abstract
The Quality of Life Scale (QLS) is a frequently used semistructured interview for the assessment of functional outcomes in schizophrenia. Despite the use of the QLS for over 30years, the original 4-factor structure of the instrument (Interpersonal Relations, Instrumental Role, Intrapsychic Foundations, and Common Objects and Activities) has not been rigorously examined. Exploratory factor analyses (EFAs) and confirmatory factor analyses (CFAs) were used to evaluate the factor structure of the QLS in two independent datasets, including a mixed diagnostic sample of multi-episode participants (N=247), and a sample of individuals with a first episode of psychosis (N=337). A CFA with the first dataset indicated a poor fit for the 4-factor model of the QLS. Subsequent EFAs on this dataset led to a more promising 3-factor solution including 16/21 of the QLS items, which were similar to the first 3 of 4 factors originally proposed for the QLS. CFAs on the same dataset indicated that the 3-factor model for the QLS-Revised (QLS-R) fit the data well. This factor structure was evaluated with the second dataset using CFA and was also found to be fit the data well. The results support the robustness of the 3-factor model of the QLS-R in schizophrenia and mixed diagnostic samples. Future research should evaluate the validity of the 3-factor model of the QLS-R, and consider the merits of changing the name of the Intrapsychic Foundations factor to Motivation.

Abstract
BACKGROUND A recent factor analysis of Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) Consensus Cognitive Battery (MCCB) data in a sample of schizophrenia-spectrum patients described a three factor model representing processing speed, attention/working memory, and learning; the social cognition measure was excluded from the analysis. The current analyses sought to replicate a three factor structure of the MCCB in a larger, more diagnostically diverse sample of participants. METHODS Confirmatory factor analyses were performed to evaluate the factor structure of the MCCB in 300 outpatients with severe mental illness (54.3% schizophrenia-spectrum diagnoses) who were participants in three studies of cognitive remediation. Exploratory analyses were conducted to evaluate the concurrent prediction of symptoms from MCCB factor scores. RESULTS The three factor structure of the MCCB demonstrated stronger model fit (χ(2)=14.53, p=0.75, SRMR=0.02, RMSEA=0.0, CFI=1.00, NNFI=1.01) than the unifactoral structure. Poorer cognitive performance across all three MCCB factors was significantly correlated with more severe overall and disorganization symptoms from the PANSS and BPRS, and less severe affective symptoms (e.g., depression, anxiety) in the overall sample. CONCLUSIONS A three factor structure of the MCCB-composed of processing speed, attention/working memory, and learning-was replicated in a heterogeneous sample of persons with severe mental illness. Cognitive performance on the MCCB factors is associated with clinical symptoms.

Abstract
If treatments for cognitive impairment are to be utilized successfully, clinicians must be able to determine whether they are effective and which patients should receive them. In order to develop consensus on these issues, the International Society for CNS Clinical Trials and Methodology (ISCTM) held a meeting of experts on March 20, 2014, in Washington, DC. Consensus was reached on several important issues. Cognitive impairment and functional disability were viewed as equally important treatment targets. The group supported the notion that sufficient data are not available to exclude patients from available treatments on the basis of age, severity of cognitive impairment, severity of positive symptoms, or the potential to benefit functionally from treatment. The group reached consensus that cognitive remediation is likely to provide substantial benefits in combination with procognitive medications, although a substantial minority believed that medications can be administered without nonpharmacological therapy. There was little consensus on the best methods for assessing cognitive change in clinical practice. Some participants supported the view that performance-based measures are essential for measurement of cognitive change; others pointed to their cost and time requirements as evidence of impracticality. Interview-based measures of cognitive and functional change were viewed as more practical, but lacking validity without informant involvement or frequent contact from clinicians. The lack of consensus on assessment methods was viewed as attributable to differences in experience and education among key stakeholders and significant gaps in available empirical data. Research on the reliability, validity, sensitivity, and practicality of competing methods will facilitate consensus.

Abstract
OBJECTIVE This study examined barriers to employment among Social Security Disability Insurance (SSDI) beneficiaries who received comprehensive vocational and mental health services but were not successful in returning to work. METHODS This study examined barriers to employment among 430 SSDI beneficiaries with mental disorders who received evidence-based vocational and mental health services for two years but worked less than one month or not at all. Comprehensive care teams, which included employment specialists, made consensus judgments for each participant, identifying the top three barriers to employment from a checklist of 14 common barriers. RESULTS Teams most frequently identified three barriers to employment: poorly controlled symptoms of mental illness (55%), nonengagement in supported employment (44%), and poorly controlled general medical problems (33%). Other factors were identified much less frequently. CONCLUSIONS Some SSDI beneficiaries, despite having access to comprehensive services, continued to experience psychiatric impairments, difficulty engaging in vocational services, and general medical problems that limited their success in employment.

Abstract
BACKGROUND A functional polymorphism of the catechol-O-methyltransferase (COMT) gene (Val158Met) partially appears to influence cognitive performance in schizophrenia subjects and healthy controls by modulating prefrontal dopaminergic activity. This study evaluated the association of the COMT Val108/158 Met genotype with response to computerized neurocognitive remediation (CRT). METHOD 145 subjects with DSM-IV-TR schizophrenia or schizoaffective disorder were genotyped via saliva sampling. Subjects were evaluated on neurocognitive assessments (MATRICS) and clinical symptoms (PANSS) at baseline and endpoint after 12weeks of CRT. "Improvement" was defined as ≥67% of cognitive domains (≥4) showing performance increases. If ≤67% (≤2) of domains improved, the change was defined as "minimal improvement." A general linear model was conducted for change of each cognitive domain. RESULTS Of 145 subjects, data from 138 subjects were usable. Distribution of COMT genotype: Met/Met: 28 (20.29%), Val/Met: 61 (44.20%), and Val/Val: 49 (35.51%). No significant differences were seen among genotype groups at baseline or across genotype group for "Improvement" vs. "Minimal Improvement." GLM analysis showed significant differences in Verbal Learning (p=0.003), Visual Learning (p=0.014) and Attention/Vigilance (p=0.011) favoring Met/Met and Val/Met groups. CONCLUSIONS The low activity Met allele (Met/Met; Val/Met) was associated with significantly greater improvements in the MATRICS domains of Verbal Learning, Visual Learning and Attention/Vigilance after CRT.

Abstract
OBJECTIVE Cognitive impairment presents a serious and common obstacle to competitive employment for people with severe mental illness, including those who receive supported employment. This study evaluated a cognitive enhancement program to improve cognition and competitive employment in people with mental illness who had not responded to supported employment. METHOD In a randomized controlled trial, 107 people with severe mental illness (46% with schizophrenia or schizoaffective disorder) who had not obtained or kept competitive work despite receiving high-fidelity supported employment were assigned to receive either enhanced supported employment (with specialized cognitive training of employment specialists) or enhanced supported employment plus the Thinking Skills for Work program, a standardized cognitive enhancement program that includes practice of computer cognitive exercises, strategy coaching, and teaching of coping and compensatory strategies. Research assistants tracked competitive employment weekly for 2 years, and assessors blind to treatment assignment evaluated cognitive functioning at baseline, at the end of cognitive enhancement training, and 12 and 24 months after baseline. RESULTS Participants in the Thinking Skills for Work group improved more than those in the enhanced supported employment only group on measures of cognitive functioning and had consistently better competitive employment outcomes during the follow-up period, including in jobs obtained (60% compared with 36%), weeks worked (23.9 compared with 9.2), and wages earned ($3,421 compared with $1,728). CONCLUSIONS The findings suggest that cognitive enhancement interventions can reduce cognitive impairments that are obstacles to work, thereby increasing the number of people who can benefit from supported employment and competitive work.

Abstract
Comprehensive coordinated specialty care programs for first-episode psychosis have been widely implemented in other countries but not in the United States. The National Institute of Mental Health's Recovery After an Initial Schizophrenia Episode (RAISE) initiative focused on the development and evaluation of first-episode treatment programs designed for the U.S. health care system. This article describes the background, rationale, and nature of the intervention developed by the RAISE Early Treatment Program project-known as the NAVIGATE program-with a particular focus on its psychosocial components. NAVIGATE is a team-based, multicomponent treatment program designed to be implemented in routine mental health treatment settings and aimed at guiding people with a first episode of psychosis (and their families) toward psychological and functional health. The core services provided in the NAVIGATE program include the family education program (FEP), individual resiliency training (IRT), supported employment and education (SEE), and individualized medication treatment. NAVIGATE embraces a shared decision-making approach with a focus on strengths and resiliency and on collaboration with clients and family members in treatment planning and reviews. The NAVIGATE program has the potential to fill an important gap in the U.S. health care system by providing a comprehensive intervention specially designed to meet the unique treatment needs of persons recovering from a first episode of psychosis. A cluster-randomized controlled trial comparing NAVIGATE with usual community care has recently been completed.

Abstract
The individual placement and supported (IPS) model of supported employment is the most empirically validated model of vocational rehabilitation for persons with schizophrenia or another serious mental illness. Over 18 randomized controlled trials have been conducted throughout the world demonstrating the effectiveness of supported employment at improving competitive work compared to other vocational programs: IPS supported employment is defined by the following principles: 1) inclusion of all clients who want to work; 2) integration of vocational and clinical services; 3) focus on competitive employment; 4) rapid job search and no required prevocational skills training; 5) job development by the employment specialist; 6) attention to client preferences about desired work and disclosure of mental illness to prospective employers; 7) benefits counseling; and 8) follow-along supports after a job is obtained. Supported employment has been successfully implemented in a wide range of cultural and clinical populations, although challenges to implementation are also encountered. Common challenges are related to problems such as the failure to access technical assistance, system issues, negative beliefs and attitudes of providers, funding restrictions, and poor leadership. These challenges can be overcome by tapping expertise in IPS supported employment, including standardized and tested models of training and consultation. Efforts are underway to increase the efficiency of training methods for supported employment and the overall program, and to improve its effectiveness for those clients who do not benefit. Progress in IPS supported employment offers people with a serious mental illness realistic hope for achieving their work goals, and taking greater control over their lives.

Abstract
TOPIC The potential of technology to enhance delivery and outcomes of Individual Placement and Support (IPS) supported employment. PURPOSE IPS supported employment has demonstrated robust success for improving rates of competitive employment among individuals with psychiatric disabilities. Still, a majority of those with serious mental illnesses are not employed (Bond, Drake, & Becker, 2012). The need to promote awareness of IPS and expand services is urgent. In this study, we describe ways that technologies may enhance delivery of IPS supported employment across the care continuum and stakeholder groups. Directions for research are highlighted. SOURCES USED published literature, clinical observations, IPS learning collaborative. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE Technology has the potential to enhance direct service as well as workflow in the IPS supported employment process, which may lead to improved fidelity and client outcomes. Mobile and cloud technologies open opportunities for collaboration, self-directed care, and ongoing support to help clients obtain and maintain meaningful employment. Research is needed to evaluate efficacy of technology-based approaches for promoting client employment outcomes, to identify provider and organization barriers to using technology for IPS delivery, and to determine effective strategies for implementing technology with IPS in different settings and with diverse client audiences.

Abstract
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.

Abstract
BACKGROUND Social cognition is significantly impaired in schizophrenia and contributes to poor community functioning. This study examined whether cognitive remediation (CR; COGPACK), shown to improve neurocognition, improves an integral component of social cognition, emotion perception, compared with CR combined with a computerized Emotion Perception intervention (Mind Reading: Interactive Guide to Emotions [MRIGE]). METHODS 59 stable schizophrenia or schizoaffective predominantly inpatients were randomized to either CR (N=27) alone or CR+MRIGE (N=32) for 12 weeks. Assessments included the Facial Emotion Identification Task (FEIT), Facial Emotion Discrimination Task (FEDT), MCCB-MATRICS, Personal and Social Performance Scale, and the Positive and Negative Syndrome Scale. RESULTS There was a significant group-by-time effect on FEIT (F=11.509, P=.004); CR+MRIGE demonstrated significantly greater improvement than CR alone (CR+MRIGE, Z=1.89, P=.05; CR alone Z=0.57, P=.13). There was significant group-by-time effect on FEDT (F=5.663, P=.022); CR+MRIGE demonstrated significantly greater improvement than CR alone (CR+MRIGE, Z=1.90, P=.05; CR alone Z=0.67, P=.21). There was also a significant group by time effect for social cognition, measured by the Mayer-Salovey-Caruso Emotional Intelligence Test (F=5.473, P=.050): CR+MRIGE demonstrated significantly greater improvement than CR alone (CR+MRIGE, Z=1.98, P=.02; CR alone, Z=1.00, P=.05). CONCLUSIONS Combined CR with emotion perception remediation produced greater improvements in emotion recognition, emotion discrimination, social functioning, and neurocognition compared with CR alone in chronic schizophrenia.

Abstract
OBJECTIVE Cognitive remediation is an efficacious treatment for schizophrenia and, when used within broader psychosocial treatments, improves transfer to real-world behavior change. The authors examined whether cognitive remediation effectively generalizes to functional competence and real-world functioning as a standalone treatment and when combined with a functional skills treatment. METHOD Outpatients with schizophrenia (N=107) were randomly assigned to receive cognitive remediation, functional adaptation skills training, or combined treatment, with cognitive remediation preceding functional skills training. Clinical symptoms, neurocognition, social competence, functional competence, and case-manager-rated real-world behavior were assessed at baseline, at end of treatment, and at a 12-week durability assessment. RESULTS Neurocognition improved, with durable effects, after cognitive remediation but not after functional skills training. Social competence improved both with functional skills training and with combined treatment but not with cognitive remediation alone. Improvements in functional competence were greater and more durable with combined treatment. Cognitive remediation alone did not produce significant improvements in real-world behavior, but when combined with functional skills training, statistically significant improvements from baseline to end of treatment and follow-up were observed in community or household activities and work skills. Number-needed-to-treat analyses suggest that as few as three cases are required for treatment to induce a meaningful improvement in functional skills. CONCLUSIONS In a short intervention, cognitive remediation produced robust improvements in neurocognition. Generalization to functional competence and real-world behavior was more likely when supplemental skills training and cognitive remediation were combined.

Abstract
OBJECTIVE Cognitive remediation therapy for schizophrenia was developed to treat cognitive problems that affect functioning, but the treatment effects may depend on the type of trial methodology adopted. The present meta-analysis will determine the effects of treatment and whether study method or potential moderators influence the estimates. METHOD Electronic databases were searched up to June 2009 using variants of the key words "cognitive," "training," "remediation," "clinical trial," and "schizophrenia." Key researchers were contacted to ensure that all studies meeting the criteria were included. This produced 109 reports of 40 studies in which ≥70% of participants had a diagnosis of schizophrenia, all of whom received standard care. There was a comparison group and allocation procedure in these studies. Data were available to calculate effect sizes on cognition and/or functioning. Data were independently extracted by two reviewers with excellent reliability. Methodological moderators were extracted through the Clinical Trials Assessment Measure and verified by authors in 94% of cases. RESULTS The meta-analysis (2,104 participants) yielded durable effects on global cognition and functioning. The symptom effect was small and disappeared at follow-up assessment. No treatment element (remediation approach, duration, computer use, etc.) was associated with cognitive outcome. Cognitive remediation therapy was more effective when patients were clinically stable. Significantly stronger effects on functioning were found when cognitive remediation therapy was provided together with other psychiatric rehabilitation, and a much larger effect was present when a strategic approach was adopted together with adjunctive rehabilitation. Despite variability in methodological rigor, this did not moderate any of the therapy effects, and even in the most rigorous studies there were similar small-to-moderate effects. CONCLUSIONS Cognitive remediation benefits people with schizophrenia, and when combined with psychiatric rehabilitation, this benefit generalizes to functioning, relative to rehabilitation alone. These benefits cannot be attributed to poor study methods.

Abstract
Performance on the Letter-Number Sequencing (LNS) and Wisconsin Card Sorting Tests (WCST) have been shown to be significantly correlated in patients with schizophrenia, a relationship postulated to be due to working memory demands of the two tests (Gold, Carpenter, Randolph, Goldberg, & Weinberger, 1997). An alternative explanation for the association between these two tests is their sorting demands, in that both require sorting of information albeit in slightly different ways. If the latter explanation is valid, then working memory tasks that do not require sorting or other conceptualization demands should be less predictive of WCST performance than LNS. These hypotheses were examined in 34 poor outcome patients with schizophrenia, one-half of whom were over the age of 65. Patients were evaluated on Digit Span Forward, spatial working memory, LNS, and the WCST. It was found that WCST performance was significantly associated with performance on the LNS but no other working memory task. Age related performance differences were greatest on the WCST Categories and floor effects were noted on this test in one-half of the subjects. Analyses predicting WCST Categories in subjects whose scores were greater than zero (n = 16) also demonstrated that LNS, but not Digit Span or spatial working memory (any delay) predicted WCST performance. These findings indicate that LNS may be an index of executive functioning, particularly in patients who cannot perform the WCST.

Abstract
Cognitive decline has been described in elderly patients with schizophrenia, but the underlying pathology remains unknown. Some studies report increases in plaques and neurofibrillary tangles, but there is no evidence for an increased risk for Alzheimer's disease (AD) in elderly schizophrenics. Models of a decreased cerebral reserve suggest that increases in AD-related neuropathology below the threshold for a neuropathological diagnosis could be related to dementia severity in elderly schizophrenia patients. We tested this hypothesis in 110 autopsy specimens of schizophrenia patients, without a neuropathological diagnosis of AD or other neurodegenerative disorders. Furthermore, we assessed the effects of apolipoprotein E (ApoE) status, a known genetic risk factor for AD. Measures of density of neuritic plaques were obtained in five cortical regions, and the degree of hippocampal neurofibrillary tangles was rated. Dementia severity was measured prior to postmortem using the Clinical Dementia Rating (CDR) scale. multivariate analyses of variance were conducted with the factors dementia severity, by ApoE4 carrier status. Hippocampal neurofibrillary tangles correlated with increased dementia severity (p<.05). Neuritic plaque density increased with greater dementia severity (p<.005), and ApoE4 carrier status (p<.005), and these differences were magnified by the ApoE4 carrier status (p<.01). Even below the threshold for a neuropathological diagnosis of AD, neuritic plaques and hippocampal neurofibrillary tangles are associated with dementia severity in schizophrenia patients, even more so in the presence of genetic risk factors, suggesting that a decreased cerebral reserve in elderly schizophrenics may increase susceptibility for dementia.
