Metacognitive Training to Improve Insight and Work Outcome in Schizophrenia.

ABSTRACT: Individuals with psychotic disorders have deficits in metacognition. Thirty-four adults with schizophrenia were randomized to 2 months of metacognitive training (MCT) or a healthy living skills control group. All participants were enrolled in a work therapy program, followed by a supported employment program. Assessments were conducted at baseline, at the end of the 2-month active intervention, and at 4- and 12-month follow-ups. At the end of active intervention, the MCT group demonstrated greater improvement and better work behavior relative to controls. At follow-up, the MCT group demonstrated significantly greater insight and fewer positive symptoms and a greater percentage were employed in the community. We speculate that being better able to think about one's thoughts, recognize biases in thinking, and correct those thoughts may aid in responding to workplace challenges and hence improve work outcomes.

The effects of cognitive-focused interventions on cognition and psychological well-being in persons with multiple sclerosis: A meta-analysis.

Cognitive impairment affects more than half of persons with multiple sclerosis (PwMS), and it is associated with difficulties in multiple aspects of daily functioning. There is a growing body of literature that has explored the use of cognitive-focused interventions in PwMS, which aim to improve cognition-related function through drill and practice exercises, training in compensatory strategies, or a combination of the two. The current study aimed to expand upon previously published meta-analyses in this area, exploring the effects of cognitive-focused interventions on objective and subjective functioning in PwMS, as well as determining demographic and treatment-related factors that may influence intervention efficacy. Thirty-three studies, with a total of 1890 participants, were included in the meta-analysis. Outcome measures were categorised based on the domain they presumably assessed. For objective cognitive functioning, weighted effect-size analysis revealed small effects of cognitive-focused interventions on working memory (g = 0.31) and visual learning (g = 0.32). Small mean effect sizes were also noted on self-reported anxiety (g = -0.30) and depression (g = -0.23). Cognitive-focused interventions did not produce changes in subjective cognitive functioning. Moderating variables and clinical applications are also discussed.

How Music Impacts Visual Attention Training in Schizophrenia: A Pilot Study.

Music has been demonstrated to improve cognitive test performance in neuropsychiatric populations. However, the impact of music on cognitive training effects, and the importance of music preference, has yet to be studied. This is an essential oversight because many cognitive training programs play music in the background. We sought to determine if participant-preferred or random music would increase the efficacy of computer-based attention training (AT). Forty-eight patients with schizophrenia were randomly assigned to 2 weeks of either: 1) AT with participants' choice of background music, 2) AT with random background music, 3) AT without music, or 4) a no training or music control-watching videos without AT or music. All groups except the no training/no music control group demonstrated improvement in reaction time and response accuracy after training, with those participating in AT with their choice of music exhibiting greater gains than either of the other two AT groups. These findings suggest that complimenting AT with music, and allowing participants to choose the music, may increase the efficacy of AT.

Decisional Informatics for Psychosocial Rehabilitation: A Feasibility Pilot on Tailored and Fluid Treatment Algorithms for Serious Mental Illness.

This study introduces a computerized clinical decision-support tool, the Fluid Outpatient Rehabilitation Treatment (FORT), that incorporates individual and ever-evolving patient needs to guide clinicians in developing and updating treatment decisions in real-time. In this proof-of-concept feasibility pilot, FORT was compared against traditional treatment planning using similar behavioral therapies in 52 adults with severe mental illness attending community-based day treatment. At posttreatment and follow-up, group differences and moderate-to-large effect sizes favoring FORT were detected in social function, work readiness, self-esteem, working memory, processing speed, and mental flexibility. Of participants who identified obtaining a General Education Diploma as their goal, 73% in FORT passed the examination compared with 18% in traditional treatment planning. FORT was also associated with higher agency cost-effectiveness and a better average benefit-cost ratio, even when considering diagnosis, baseline symptoms, and education. Although the comparison groups were not completely equivalent, the findings suggest computerized decision support systems that collaborate with human decision-makers to personalize psychiatric rehabilitation and address critical decisions may have a role in improving treatment effectiveness and efficiency.

Comparing three methods of computerised cognitive training for older adults with subclinical cognitive decline.

Cognitive rehabilitation for mild cognitive impairment (MCI) and early Alzheimer's disease is readily available to the geriatric population. Initial evidence suggests that techniques incorporating motivational strategies to enhance treatment engagement may provide more benefit than computerised training alone. Seventy four adults with subclinical cognitive decline were randomly assigned to computerised cognitive training (CCT), Cognitive Vitality Training (CVT), or an Active Control Group (ACG), and underwent neuropsychological evaluations at baseline and four-month follow-up. Significant differences were found in changes in performance on the Modified Mini Mental State Examination (mMMSE) and measures of verbal learning and memory across treatment groups. Experimental groups showed greater preservation of functioning on the mMMSE than the ACG group, the CVT group performed better than the ACG group on one measure of verbal learning and both measures of verbal memory, and the CCT group performed better than the ACG group on one measure of verbal learning and one measure of verbal memory. There were no significant group differences between the CVT and CCT groups on measures of verbal learning or memory. It was concluded that computerised cognitive training may offer the most benefit when incorporated into a therapeutic milieu rather than administered alone, although both appear superior to more generic forms of cognitive stimulation.

Addressing defeatist beliefs in work rehabilitation.

BACKGROUND: Adults with serious mental illness (SMI) may struggle with expectations of failure in vocational rehabilitation. These expectations can be global and trait-like or performance-specific and related to ability. AIMS: To date, it has not been examined whether global or performance-specific defeatist beliefs are related to functional outcomes. METHOD: The Indianapolis Vocational Intervention Program (IVIP) is a CBT intervention used to address expectations of failure and improve work performance. We examined the relationships between defeatist beliefs, self-esteem, social functioning, and work behaviors in 54 adults with SMI who completed IVIP within a work therapy program. RESULTS: Baseline work-specific defeatist beliefs were related to baseline self-esteem, employment attitude, and work behaviors. Decline in work-specific defeatist beliefs was associated with better social functioning, self-esteem, and work behaviors. Decline in global defeatist beliefs was only associated with improvements in social functioning. CONCLUSIONS: Performance-specific expectations about work may be an appropriate therapeutic target to enhance work outcome in SMI.

Comparison of self-report and performance-based measures of everyday functioning in individuals with schizophrenia: implications for measure selection.

INTRODUCTION: Both self-report and performance-based measures are often used in assessment of everyday functioning for individuals with schizophrenia. However, there is little evidence of overlap between them, and there are no established standards for which measures might be most appropriate. In order to better understand differences among these types of measures, we examined relationships between a self-report and two performance-based measures of everyday functioning. We also examined their patterns of interrelationships to neurocognition and psychiatric symptoms. METHODS: Participants were 71 outpatients with schizophrenia spectrum disorder. Measures of everyday functioning (Independent Living Skill Survey-Self Report (ILSS-SR); University of California San Diego Performance-based Skills Assessment; and Medication Management Ability Assessment), cognition and psychiatric symptoms were administered. Correlation analyses were conducted to examine the relationships among the functioning measures, and their relationships to cognition and symptoms. Regression analyses further examined the unique contributions of neurocognitive and symptom variables to functional measures. RESULTS: Consistent with the literature, the two performance-based measures were related to each other, but not to the self-report measure. Whereas the performance-based measures were related to neurocognition but not to the psychiatric symptoms, the opposite pattern was observed for the self-report measure. CONCLUSIONS: The pattern of interrelationships among these self-report and performance-based measures suggests that they tap different aspects of everyday functioning. This has important implications for measure selection, particularly for evaluating intervention outcomes. When targeting symptoms, a self-report measure like the ILSS-SR may be more appropriate, whereas a performance-based measure may be more sensitive to functional changes subsequent to treatments targeting cognition.

Efficacy of cognitive training on cognition, symptoms and functioning: Impact of motivation and attendance.

While cognitive remediation therapy (CRT) and compensatory strategy training both have large literature bases supporting their efficacy on both proximal and distal outcomes, the research base on stand-alone cognitive training (CT) is smaller and less consistent, with little information about factors associated with better outcomes. In this study, we examined the efficacy of CT on training task, cognitive, symptom, and functional ability measures as well as the impact of motivational interviewing (MI), motivation level, and session attendance on treatment outcomes. Adults with psychotic spectrum disorders (n = 114) were randomized to MI or a sham control interview (CI), followed by 4 months of computerized CT. In whole sample analyses, participants improved on training tasks, cognitive performance, and psychiatric symptoms, but self-reported cognition, self-reported depression, and functional ability did not change. Compared to CI, MI was associated with greater reductions in self-reported depressive symptoms. Motivation level and session attendance did not significantly influence outcomes. Findings support the efficacy of CT on several key outcomes, and its simplicity may be advantageous in uptake in community clinics with limited staffing. The lack of functional gains underscores the need to incorporate treatment ingredients that promote generalization and real-world implementation of learned skills. We also speculate that engagement during course of training may be a better predictor of training success than baseline task-specific motivation.

Group-Based Metacognitive Reflection and Insight Therapy (MERITg) and Its Relationship to Recovery-Oriented Beliefs in Serious Mental Illness.

Group-based Metacognitive Reflection and Insight Therapy (MERITg) is the group application of Metacognitive Reflection and Insight Therapy (MERIT), an evidence-based, integrative, recovery-oriented intervention to enhance insight and understanding of oneself and others in individuals with serious mental illness (SMI). MERITg may offer therapeutic interactions between participants that uniquely support recovery. The goal of the current study was to examine the relationship between MERITg participation and recovery-oriented beliefs. Thirty-one participants (outpatient = 21; inpatient = 10) in SMI treatment programs participated in MERITg as an adjunctive treatment. A short form of the Maryland Assessment of Recovery in Serious Mental Illness (MARS-12) was used to assess recovery-oriented beliefs before and after group participation. Recovery-oriented beliefs significantly improved in the outpatient MERITg group but not in the inpatient group, and change in recovery-oriented beliefs was positively correlated with the total number of groups attended. These findings suggest the promise of MERITg for enhancing recovery-oriented beliefs. The potential role of treatment setting is discussed.

Beyond cognition: a longitudinal investigation of the role of motivation during a vocational rehabilitation program.

Studies that have specifically examined the effects of motivation on work have been limited to evaluations of baseline motivation and have not accounted for cognition. These have also not examined whether motivation changes over time. In the current analyses, we examined how baseline motivation and longitudinal changes in motivation, along with the effects of baseline cognition, related to work function in a sample of 123 individuals with schizophrenia or schizoaffective disorder participating in a 26-week vocational rehabilitation program. Our results indicate that cognition at baseline was a significant predictor of work outcomes over time. Baseline motivation and changes in motivation were significantly linked to work outcomes. The impact of motivation remained significant even after accounting for baseline cognition. These findings provide evidence that motivation is malleable during vocational rehabilitation and has an important impact on vocational function above and beyond the impact of cognition.

Efficacy of social cognition and interaction training in outpatients with schizophrenia spectrum disorders: randomized controlled trial.

Given the relationship between social cognition and functional outcome in schizophrenia, a number of social cognitive interventions have been developed, including Social Cognition Interaction Training (SCIT), a group-based, comprehensive, manualized intervention. In the current trial, we examined SCIT efficacy as well as potential moderators of treatment effects. Fifty-one outpatients were randomized to SCIT or a wait-list-control (WLC), with assessments of social cognition, neurocognition, self-report, symptoms, and functioning conducted at baseline and end of the active phase. Relative to WLC, we did not find significant improvements for SCIT on neurocognition, social cognition, self-report, or symptoms, though there was a trend-level, medium effect favoring the SCIT condition on interpersonal and instrumental role function. Post-hoc analyses indicated that baseline neurocognition did not impact degree of social cognitive or functional change. Shorter duration of illness was significantly associated with better post-training neurocognition and self-esteem and, at trend-level with better symptoms and social functioning. We discuss the importance of outcome measure selection and the need for continued evaluation of potential treatment moderators in order to better match people to existing treatments.

Motivational interviewing to enhance psychosocial treatment attendance in people with SMI.

BACKGROUND: While there is increasing support for the efficacy of psychosocial interventions for people with SMI, the real-world effectiveness of such treatments is diminished by lack of motivation for treatment, leading to poor treatment engagement/dropout. We sought to evaluate the efficacy of motivational interviewing (MI) in improving attendance in a full course of cognitive training, examine motivation level as a potential mechanism of action, and examine variables associated with initial engagement in the training. METHODS: One hundred fourteen participants with SMI were randomized to MI or sham control interview (CI), both of which were followed by a 4-month active phase during which participants could attend up to 50 unpaid cognitive training sessions. RESULTS: Fidelity to the MI intervention was high, and MI condition was associated with increases in perceived value of training tasks and, to a lesser extent, how enjoyable/interesting they were rated. Twenty-nine percent of the full sample did not attend any training sessions. In ITT analyses, there was no significant between-group impact of MI on treatment attendance, though one emerged when participants who did not attend any sessions were excluded. Treatment attendance was predicted by the level of motivation achieved after the MI/CI intervention. Those who attended at least one training session (regardless of randomization) were more likely to believe they had cognitive impairments, had higher IQ and had less severe general psychiatric symptoms. CONCLUSIONS: MI showed some promise and may be a worthwhile addition to more comprehensive, robust efforts to promote initial treatment engagement and subsequent adherence.

Intrinsic motivation as a predictor of work outcome after vocational rehabilitation in schizophrenia.

Intrinsic motivation is a construct commonly used in explaining goal-directed behavior. In people with schizophrenia, intrinsic motivation is usually subsumed as a feature of negative symptoms or underlying neurocognitive dysfunction. A growing literature reflects an interest in defining and measuring motivational impairment in schizophrenia and in delineating the specific role of intrinsic motivation as both an independent predictor and a mediator of psychosocial functioning. This cross-sectional study examined intrinsic motivation as a predictor of vocational outcomes for 145 individuals with schizophrenia and schizoaffective disorder participating in a 6-month work rehabilitation trial. Correlation and mediation analyses examined baseline intrinsic motivation and negative symptoms in relation to work hours and work performance. Data support a significant relationship between intrinsic motivation and negative symptoms and significant correlations with outcome variables, such that lower negative symptoms and greater intrinsic motivation were associated with better work functioning. Moreover, in this sample, intrinsic motivation fully mediated the relationships between negative symptoms, work productivity, and work performance. These results have significant implications on the design of work rehabilitation interventions for people with schizophrenia and support a role for targeting intrinsic motivation directly to influence vocational functioning. Future directions for research and intervention are discussed.

Comparison of computational methods for the evaluation of learning potential in schizophrenia.

Learning potential (LP) refers to the ability to improve cognitive performance as a result of training. It is typically assessed by test-train-test administrations of a task, wherein changes in pre-post performance are an index of LP. In schizophrenia research, LP has been suggested as a mediator of the relationship between static neurocognition and functional outcome. While a number of studies do indicate that LP assessment improves prediction of functioning beyond standard administrations of the same task, multiple approaches of computing LP indices have been used in this work. Multiple psychometric issues have been raised with respect to computation of change scores, but have not been widely recognized in LP assessment. To address this issue, the current study aimed to evaluate the test-retest reliability, interrelatedness, construct, and criterion validity of several conventional indices of LP, obtained from a test-train-test version of a list-learning task administered to 43 individuals with chronic schizophrenia. Overall, test-retest and intercorrelation coefficients indicated variable reliability and convergence across methods. While LP indices generally correlated more highly with independent measures of neurocognition and community functioning than pretraining list learning scores, coefficients were comparably small. Recommendations and measurement issues inherent to the LP construct are discussed.

Functional significance of preserved affect recognition in schizophrenia.

Affect recognition (AR) is a core component of social information processing; thus, it may be critical to understanding social behavior and functioning in broader aspects of daily living. Deficits in AR are well documented in schizophrenia, but there is also evidence that many individuals with schizophrenia perform AR tasks at near-normal levels. In the current study, we sought to evaluate the functional significance of AR deficits in schizophrenia by comparing subgroups with normal-range and impaired AR performance on proxy and interviewer-rated measures of real-world functioning. Schizophrenia outpatients were classified as normal-range (N=17) and impaired (N=31) based on a logistic cut point in the sample distribution of Bell-Lysaker Emotion Recognition Task (BLERT) scores, referenced to a normative sample of healthy control subjects (N=56). The derived schizophrenia subgroups were then compared on proxy [University of California San Diego Performance-Based Skill Assessment (UPSA), Social Skills Performance Assessment (SSPA), Medication Management Ability Assessment (MMAA)] and interviewer-rated [Quality of Life Scale (QLS), Independent Living Skills Survey (ILSS)] measures of functioning, as well as a battery of neurocognitive tests. Initial analyses indicated superior MMAA and QLS performance in the near-normal AR subgroup. Covariate analyses indicated that group differences in neurocognition fully mediated the observed associations between AR and MMAA, and attenuated the observed relationships between AR classification and QLS. These results support three main conclusions. First, AR, like many other domains of psychopathology studied in schizophrenia, is preserved in select subgroups. Second, there is a positive relationship between AR performance and functional outcome measures. Third, neurocognition appears to mediate the relationship between AR and measures of functioning.

What variables predict cognitive remediation associated improvement in individuals with psychosis?

On average, cognitive remediation (CR) is effective in improving cognitive function in individuals with psychosis, though there is considerable variability in treatment response. No consensus has emerged to date about the potential influence of patient and illness characteristics on CR efficacy. In the current analyses, we examined baseline demographic, cognitive, clinical, and functional ability variables as potential moderators of cognitive improvements during a randomized, controlled trial of a hybrid drill-and-practice plus strategy training CR intervention. In an attempt to disentangle non-specific vs. CR specific treatment effects, we separately examined potential predictors of cognitive improvement in individuals who received CR versus those in the control condition. Cognitive gains were predicted by a large array of demographic, symptom and cognitive variables, however this was true both in the CR and the control condition. CR-specific cognitive improvement was associated with more severe course of illness as indexed by higher number of hospitalizations, with poorer baseline cognition, and with less severe baseline negative symptoms.

Randomized clinical trial of Cognitive Remediation Therapy with Work Therapy in the early phase of substance use disorder recovery for older Veterans: 12-Month follow-up.

OBJECTIVE: In a previous report on a randomized clinical trial of a 3-month program of Cognitive Remediation Therapy (CRT) augmented by Work Therapy (WT) compared with WT alone for older veterans with substance use disorder (SUD), we reported significantly greater improvements at six-month follow-up on neurocognitive outcomes of working memory and executive functions for the CRT + WT condition. However, no difference was found between conditions on SUD outcomes, with both groups showing unusually high levels of abstinence. In this study, we extended follow-up to 12 months to test whether there was an SUD outcome "sleeper effect" from CRT + WT. To better understand the effects of WT, we added a treatment-as-usual (TAU) comparison sample. METHOD: Forty-eight veterans with SUD receiving standard outpatient VA care were randomized into CRT + WT or WT. Clinical Global Impression (CGI) ratings were performed on 43/48 participants with up-to-date medical records. A TAU comparison group (n = 44) with similar demographic and illness characteristics was added to the analysis. RESULTS: Treatment groups did not differ significantly at 12 months on CGI (p = 0.27), with 77% receiving CRT + WT showing favorable SUD outcomes compared to 62% in WT. Both groups had better CGI outcomes (p < 0.01) compared to the TAU comparison group (27%). Hours of WT participation (r = -0.49, p = 0.001) and hours of CRT (r = -0.45, p = 0.048) were associated with better CGI scores. CONCLUSION: While no sleeper effect was found for CRT, a robust effect was strongly supported for WT on SUD outcomes.

Cognitive remediation for schizophrenia: An expert working group white paper on core techniques.

Cognitive remediation is now widely recognized as an effective treatment for cognitive deficits in schizophrenia. Its effects are meaningful, durable, and related to improvements in everyday functional outcomes. As with many therapies, the evolution of cognitive remediation has resulted in treatment programs that use a variety of specific techniques, yet share common core principles. This paper is the product of a cognitive remediation expert working group consensus meeting to identify core features of the treatment and produce recommendations for its design, conduct, reporting, and implementation. Four techniques were identified as core features of cognitive remediation: facilitation by a therapist, cognitive exercise, procedures to develop problem-solving strategies, and procedures to facilitate transfer to real world functioning. Treatment techniques within each of these core features are presented to facilitate decisions for clinical trials and implementation in clinical settings.

The synergistic benefits of physical and cognitive exercise in schizophrenia: Promoting motivation to enhance community effectiveness.

Emerging research highlights the potential cognitive benefits of physical exercise (PE) programs for schizophrenia (SCZ). The few recent efficacy studies that examined augmenting cognitive training (CT) with PE suggest superior effects of the combination. The next step is to consider strategies to enhance adherence in real-world settings if this type of combined treatment is going to be effective. We present the first community effectiveness data for PE and CT that included a motivationally-enhancing, self-determined approach to exercise, in lieu of participant payment. Eighty-five outpatients with schizophrenia attending an intensive outpatient program were randomized to 18 h of either (A) self-determined PE regimen with choice from a menu of different activities; (B) tablet-based neurofeedback CT focused on processing speed (PS) and working memory (WM), or (C) a time-matched combination of PE and CT. Assessments were conducted at baseline, post, and follow-up (2 mo). All groups improved in WM from baseline to post, with greatest gains in the PE only group. At follow-up, cognitive gains originally observed in the PE-only group disappeared, while the PE + CT group evidenced improvements in WM and psychotic symptoms. Notably, attrition for PE was only 7%. Our data shows that combining PE and CT leads to lasting effects that are superior to those of either intervention alone. The low PE drop-out rate suggests a self-determined approach to the exercise regimen was tolerable, and may be an important component of future community implementation efforts.

Attention training in schizophrenia: differing responses to similar tasks.

Cognitive retraining is a promising non-pharmacological approach to the treatment of neurocognitive deficits in schizophrenia. The current study aimed to learn whether people with schizophrenia improve on attention tasks, whether individual performance varies by task, and what task improvement measures relate to pre-post-change in neuropsychological tests of attention. Thirty-two outpatients with schizophrenia or schizoaffective disorder completed at least 40 cognitive training hours on two computerized visual attention training tasks (VT1 and VT2) and pre-post-testing with Digit Span, Digit Symbol Substitution Task, and Continuous Performance Task. Performance slopes indicated significant improvement on both training exercises. Despite apparent similarities between the two training tasks, there were no significant correlations between performance measures on VT1 and VT2. Significant relationships were found between performance improvement variables and change scores on neuropsychological measures, but these relationships varied by training task. Results indicate that cognitive training was effective in improving task performance but that similar tasks can be different in who performs well and what components of attention may be affected. Findings suggest that training should involve multiple exercises within the same domain and that multiple measures may be important in making links between the training process and functional outcomes.
