Is it time to develop a new cognitive therapy for psychosis--cognitive remediation therapy (CRT)?

Cognitive Rehabilitation in Schizophrenia-Associated Cognitive Impairment: A Review

Patients suffering from schizophrenia often experience cognitive disturbances. Cognitive rehabilitation-computerized or non-computerized-is widely known as an alternative way to enhance cognitive functioning in patients with schizophrenia. The aim of the present review was to examine the role of cognitive rehabilitation (both computerized and non-computerized) for the alleviation of cognitive impairment in schizophrenia patients. Fourteen relative studies were examined and included in the present review. The results revealed that both computerized and non-computerized cognitive rehabilitation could enhance cognitive functioning and more specifically memory, attention, executive functioning, processing speed and in a few cases, even non-cognitive impairments, such as other schizophrenia symptoms. The present results support the efficacy of cognitive rehabilitation in schizophrenia patients, regardless of whether it is computerized or non-computerized. As the randomized control trials (RCTs) are limited in number, there is urgent need for more RCTs and longitudinal studies combining different kinds of interventions, as well as systematic reviews and meta-analyses, in order to further investigate and confirm the current results.

Cognitive Optimisation and Schizophrenia: Assembling Heterogeneity, Overcoming the Precariousness of Life, and Challenging Public Health Policies in Psychiatry in France

Cognitive remediation therapy (CRT) aims to optimise cognitive abilities of people who suffer from schizophrenia in order to improve their social adaptation. This therapeutic orientation was developed in psychiatry in the 1980s and 1990s, at a time when the disorder was being redefined as a neurocognitive deficit disorder. In this article, I describe CRT as an assemblage that lies at the intersection of multiple, overlapping theories and spaces of mental disorders and psychiatric care. To do so, I draw on 18 months of ethnographic research conducted in a French hospital unit dedicated to the development of CRT. I argue that the focus on cognitive health and cognitive abilities (or deficits) is not only redefining the logics of care and reshaping medical conceptualisations of schizophrenia, but it is also opening up to a new understanding of people's precarious life conditions, where emotional, biological, and cognitive fragility is intertwined with social and economic uncertainty. I then examine the extent to which psychiatrists have extended the goals of CRT to include psychosocial rehabilitation in order to mitigate not only the effects of cognitive deficits, but also the effects of limited social and professional integration encountered by patients. Finally, I conclude with a consideration of how CRT has become, for its proponents in France, a means to develop a policy and organisational project for French psychiatry.

It is time to address language disorders in schizophrenia: A RCT on the efficacy of a novel training targeting the pragmatics of communication (PragmaCom)

INTRODUCTION

Language and communication disruptions in schizophrenia are at the center of a large body of investigation. Yet, the remediation of such disruptions is still in its infancy. Here we targeted what is known to be one of the most damaged language domains in schizophrenia, namely pragmatics, by conducting a pragmatics-centered intervention with a randomized controlled trial design and assessing also durability and generalization. To the best of our knowledge, this is the first study with these characteristics.

METHODS

Inspired by the Gricean account of natural language use, we tailored a novel treatment addressing the pragmatics of communication (PragmaCom) and we tested its efficacy in a sample of individuals with schizophrenia randomized to the experimental group or to an active control group. The primary outcome with respect to the efficacy of the PragmaCom was measured by changes in pragmatic abilities (as evaluated with the global score of the Assessment of Pragmatic Abilities and Cognitive Substrates test) from baseline to 12 weeks and at 3-month follow-up. The secondary outcome was measured by changes in metaphor comprehension, abstract thinking, and global functioning from baseline to 12 weeks and at 3-month follow-up.

RESULTS

Relative to the control group, at post-test the PragmaCom group showed greater and enduring improvement in global pragmatic skills and in metaphor comprehension. At follow-up, these improvements persisted and the PragmaCom exerted beneficial effects also on functioning.

CONCLUSIONS

Despite the limited sample size, we believe that these findings offer initial yet encouraging evidence of the possibility to improve pragmatic skills with a theoretically grounded approach and to obtain durable and clinically relevant benefits. We argue that it is time that therapeutic efforts embrace communicative dysfunctions in order to improve illness outcome.

A Conceptual View of Cognitive Intervention in Older Adults With and Without Cognitive Decline-A Systemic Review

Background: Dementia is the one of the most common and prominent disease in the elderly person that results in the Cognitive interventions. In this study, we aim to conceptualize the cognitive intervention for older adults with and without cognitive dysfunction and to clarify the heterogeneity existing in this literature field by determining the main variables implicated. Methods: We conducted a study analysis using previous literature highlighting the significant data reporting empirical results from cognitive intervention for healthy older adults and other seniors with different types of dementia. Each paper was reviewed in terms of compensatory cognitive training, cognitive remediation, enrichment, cognitive activation, brain training, cognitive stimulation, cognitive training, and cognitive rehabilitation. The research analysis was performed following rigorous inclusion and exclusion criteria with the purpose of collecting relevant answers to our research questions. Results: We included a total of 168 studies in our review. Our findings indicated heterogeneity regarding methods, concepts, and procedures. Additionally, the values were integrated using different information existing in this field. Conclusion: In conclusion, we highlighted that this is the first review that clarify the discrepancy of various existing definitions, methods, and procedures, as well as the overlapping information in the cognitive interventions.

Brain Stimulation and Group Therapy to Improve Gesture and Social Skills in Schizophrenia-The Study Protocol of a Randomized, Sham-Controlled, Three-Arm, Double-Blind Trial

An important component of nonverbal communication is gesture performance, which is strongly impaired in 2/3 of patients with schizophrenia. Gesture deficits in schizophrenia are linked to poor social functioning and reduced quality of life. Therefore, interventions that can help alleviate these deficits in schizophrenia are crucial. Here, we describe an ongoing randomized, double-blind 3-arm, sham-controlled trial that combines two interventions to reduce gesture deficits in schizophrenia patients. The combined interventions are continuous theta burst stimulation (cTBS) and social cognitive remediation therapy (SCRT). We will randomize 72 patients with schizophrenia spectrum disorders in three different groups of 24 patients. The first group will receive real cTBS and real SCRT, the second group will receive sham cTBS and real SCRT, and finally the third group will receive sham SCRT. Here, the sham treatments are, as per definition, inactive interventions that mimic as closely as possible the real treatments (similar to placebo). In addition, 24 age- and gender-matched controls with no interventions will be added for comparison. Measures of nonverbal communication, social cognition, and multimodal brain imaging will be applied at baseline and after intervention. The main research aim of this project will be to test whether the combination of cTBS and SCRT improves gesture performance and social functioning in schizophrenia patients more than standalone cTBS, SCRT or sham psychotherapy. We hypothesize that the patient group receiving the combined interventions will be superior in improving gesture performance.

Cognitive remediation to improve the vocational outcomes of people with severe mental illness

The present study investigates the effects of cognitive remediation (CR) training with Individual Placement and Support (IPS) in people suffering from severe mental illness in European population (Spanish). Sixty-five participants (83% with schizophrenia or bipolar disorder) were recruited from community mental health teams. Fifty-seven met the criteria and agreed to participate in the study. The conditions of cognitive rehabilitation were assigned randomly with support employment CR + IPS (n = 28) and IPS alone (n = 29). Two groups were followed at 8 and 12 months after the baseline. Participants in the CR + IPS group improved more than the IPS only group during the follow-up period in measures of cognitive functioning (significantly higher in executive functions, verbal learning and memory) and obtained higher employment percentages during the follow-up period, including people who got a job after 8 months (52.2% versus 29.2%, p = .023) and after 1 year (60.9% versus 37.5%, p = .025), as well as, in the weekly hours worked (37.2 versus 26.7 h, p = .023). Retention in the CR + IPS program was high (82.14%). The calculated global cognitive score showed that the evolution over time differed significantly between groups (p < .001).

Psychological interventions in psychosis in children and adolescents: a systematic review

BACKGROUND

Early onset psychosis (EOP), referring to psychosis with onset before the age of 18 years, is a more severe form of psychosis associated with worse prognosis. While medication is the treatment of choice, psychological interventions are also considered to have an important role in the management of symptoms and disability associated with this condition. The present review aimed to explore the effectiveness of such interventions.

METHOD

An electronic search was conducted on the Embase, Medline, and PsychInfo databases for papers of randomized controlled trials (RCTs) referring to psychological interventions in EOP. References of identified papers were hand searched for additional studies. Identified studies were quality assessed.

RESULTS

Eight studies were included in the present review evaluating cognitive remediation therapy (CRT), cognitive behavioural therapy (CBT), a family intervention and psychoeducation. CRT was associated with improvement in cognitive function and CBT and CRT seem to also have a positive effect in psychosocial functioning. Symptom reduction appears to not be significantly affected by the proposed treatments.

CONCLUSIONS

There is some evidence supporting the effectiveness of psychological interventions in EOP. However, most research on adolescents is focused on CRT and its effects on cognitive deficits. More studies on the effects of psychological interventions in EOP are needed.

From cognitive and clinical substrates to functional profiles: Disentangling heterogeneity in schizophrenia

The relationship between neurocognition and functioning among patients with schizophrenia is well documented. However, integrating neuropsychological, clinical and psychopathological data to better investigate functional outcome still constitutes a challenge. Artificial neural network-based modeling might help to better capture clinical heterogeneity by analyzing the non-linear relationships among multiple variables. Two hundred and fourteen clinically stabilized patients with schizophrenia were recruited and assessed for neurocognition, psychopathology and functioning. Artificial neural network analyses were conducted to yield significant predictors of functional outcome among clinical and cognitive variables and to build distinct functional Profiles, each characterized by a different medley of cognitive and clinical features. Twenty-two key predictors of daily functioning emerged, encompassing neurocognitive and clinical domains, with major roles for processing speed and attention. Four Profiles were constructed based on specific levels of functioning, each characterized by a distinct distribution of key clinical and neurocognitve measures. This study highlights the importance of a more in-depth investigation of cognitive and clinical heterogeneity. A better understanding of the building blocks of these Profiles would lead to more individualized rehabilitation treatments.

[Tunisia: nursing practice of cognitive remediation in child psychiatry]

Cognitive remediation is today afforded a significant place in the treatment of neurodevelopmental disorders. A hospital team, comprising in particular a nurse offering consultations in a child psychiatry unit in a public hospital in Tunis, shares its experience with regard to this technique which aims to restore impaired cognitive functions in order to improve the efficiency and quality of life of young patients.

A 10-minute measure of global cognition: Validation of the Brief Cognitive Assessment Tool for Schizophrenia (B-CATS)

INTRODUCTION

Schizophrenia is marked by a global cognitive impairment that contributes significantly to chronic disability and unemployment. As new treatments are developed for cognition in schizophrenia, clinicians require easily administered instruments to assess cognition. We previously developed a very brief cognitive battery (Bell et al., 2005). The Brief Cognitive Assessment Tool for Schizophrenia (B-CATS) was developed specifically to provide clinicians with a way to assess cognition in their patients with schizophrenia. Here, we report the results of a validity study comparing B-CATS to a larger neurocognitive battery, the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) battery.

METHODS

Outpatients with schizophrenia (N=91) were administered the B-CATS and the non-overlapping tests of the MATRICS battery at two time points separated by 1month. They were also administered the UCSD Performance-based Skills Assessment-Brief (UPSA-B), a measure of functional capacity.

RESULT

The B-CATS has an administration time of approximately 10min. It demonstrates good test-retest reliability and internal consistency. It correlates 0.76 (p<0.01) with the MATRICS battery. The shorter B-CATS and the MATRICS battery correlate with the UPSA-B at 0.50 and 0.58 respectively.

CONCLUSION

A 10-minute version of the B-CATS correlates highly with the "gold standard" neurocognitive battery that has an administration time of over 60min. Both measures correlate moderately with a measure of functional capacity. This brief battery was designed to allow clinicians to monitor cognitive change and better inform treatment decisions.

The role of premorbid adjustment in schizophrenia: Focus on cognitive remediation outcome

Premorbid adjustment has been associated with several outcomes in schizophrenia and has been proposed as an index of cognitive reserve. This study aims to comprehensively analyse the relation between premorbid adjustment and clinical, neurocognitive, socio-cognitive and functional assessments, as well as to investigate the effect of premorbid adjustment on cognitive improvements after a cognitive remediation therapy protocol. Seventy-nine clinically stabilised outpatients with schizophrenia underwent a combined intervention consisting of cognitive remediation therapy added to standard rehabilitation therapy. All patients were assessed at baseline for psychopathology, premorbid adjustment, intellectual level, cognition and functioning. Cognitive evaluations were also repeated after the intervention. At baseline, significant correlations were observed between premorbid adjustment and working memory. The global cognitive improvement after treatment was significantly predicted by age and premorbid adjustment. This study confirms the association between premorbid adjustment and cognitive impairment and is the first to highlight the possible role of premorbid adjustment on the capacity to recover from cognitive deficits through a cognitive remediation therapy protocol. The data suggest that cognitive remediation may be particularly effective for people in the early course and that the assessment of premorbid adjustment could be of value to design individualised interventions.

Integrated cognitive remediation and standard rehabilitation therapy in patients of schizophrenia: persistence after 5years

Cognitive remediation, often used in combination with standard rehabilitation programs, represents the best available tool to treat cognitive impairments in patients with schizophrenia. However, there are still open questions about durability of effects and generalization of cognitive improvements to functional outcome. This study aims to investigate the persistence of both cognitive and functional effects of combined cognitive remediation plus standard rehabilitation interventions, 5years after completion of the intervention, also comparing different durations of the standard rehabilitation. Sixty patients diagnosed with schizophrenia and previously treated with a 6months intervention, consisting of standard rehabilitation plus 3-months of cognitive remediation, either followed by another year of standard rehabilitation or routine psychiatric treatment, were reassessed with neuropsychological and functional measures 5years after the intervention. Results show that cognitive abilities remained stable after 5years in both groups, while functional performance significantly decreased in patients treated with the 6months intervention only. Data thus suggest that cognitive effects persist even after 5years, while a longer standard rehabilitation following the cognitive remediation program may be needed to achieve a stable functional gain.

Evaluation of individual cognitive remediation therapy (CRT) for the treatment of young people with anorexia nervosa

PURPOSE

Research suggests that there are cognitive inefficiencies underlying Anorexia Nervosa (AN), with CRT showing promise in improving these inefficiencies in adults. This area has yet to be explored in a younger population. The aim of this study was to evaluate the use of CRT for young people.

METHODS

A within-subjects design was used to compare the performance of children and adolescents with AN on several neuropsychological measures administered before and after a course of CRT.

RESULTS

Ninety-two female participants diagnosed with AN aged between 11 and 17 (M = 14.8, SD = 1.6), all receiving treatment at a specialist inpatient unit. The assessment consisted of the Rey-Osterrieth Complex Figure test (ROCFT), the Behaviour Rating Inventory of Executive Function-Self-Report (BRIEF-SR), and the D-KEFS Colour-Word Interference Test (CWT). Repeated-measures t tests were used to analyse the ROCFT and BRIEF-SR data. There was a significant improvement in Central Coherence Index (p < .001), Immediate Recall (p < .001), Shift (p < .001) Cognitive Shift (p = 002), Behavioural shift (p < .001), Emotional Control (p < .001), Working Memory (p = .001), Plan/Organize (p < .001), Monitor (p = .001) BRI (p < .001), MI (p = .001), and GEC (p < .001). On the D-KEFS CWT, a repeated-measure Wilcoxon signed-rank test revealed a significant improvement in Error Rate (p = .019) and a repeated-measures t test revealed a significant improvement in time taken (p < .001).

CONCLUSIONS

Results suggest that CRT for children and adolescents with AN could strengthen specific cognitive domains.

Correlation Between Brain Activation Changes and Cognitive Improvement Following Cognitive Remediation Therapy in Schizophrenia: An Activation Likelihood Estimation Meta-analysis

Background:

Several studies using functional magnetic resonance imaging (fMRI) and positron emission tomography (PET) have indicated that cognitive remediation therapy (CRT) might improve cognitive function by changing brain activations in patients with schizophrenia. However, the results were not consistent in these changed brain areas in different studies. The present activation likelihood estimation (ALE) meta-analysis was conducted to investigate whether cognitive function change was accompanied by the brain activation changes, and where the main areas most related to these changes were in schizophrenia patients after CRT. Analyses of whole-brain studies and whole-brain + region of interest (ROI) studies were compared to explore the effect of the different methodologies on the results.

Methods:

A computerized systematic search was conducted to collect fMRI and PET studies on brain activation changes in schizophrenia patients from pre- to post-CRT. Nine studies using fMRI techniques were included in the meta-analysis. Ginger ALE 2.3.1 was used to perform meta-analysis across these imaging studies.

Results:

The main areas with increased brain activation were in frontal and parietal lobe, including left medial frontal gyrus, left inferior frontal gyrus, right middle frontal gyrus, right postcentral gyrus, and inferior parietal lobule in patients after CRT, yet no decreased brain activation was found. Although similar increased activation brain areas were identified in ALE with or without ROI studies, analysis including ROI studies had a higher ALE value.

Conclusions:

The current findings suggest that CRT might improve the cognition of schizophrenia patients by increasing activations of the frontal and parietal lobe. In addition, it might provide more evidence to confirm results by including ROI studies in ALE meta-analysis.

Maladaptive emotion regulation strategies and stress sensitivity mediate the relation between adverse life events and attenuated positive psychotic symptoms

INTRODUCTION

There is now solid evidence for a relation between adverse life events (ALE) and psychotic symptoms in patients with psychosis and in the general population. A recent study has shown that this relation may be partially mediated by stress sensitivity, suggesting the influence of other factors. The aim of this study was to assess the mediation effect of emotion regulation strategies and stress sensitivity in the relation between ALE and attenuated positive psychotic symptoms (APPS) in the general population.

METHODS

Hundred and twelve healthy volunteers were evaluated with measures of APPS, emotion regulation strategies, ALE and stress sensitivity.

RESULTS

Results demonstrated that the relation between ALE, hallucination and delusion proneness was completely mediated by maladaptive emotion regulation strategies, but not by stress sensitivity. However, in addition to maladaptive emotion regulation strategies, stress sensitivity demonstrated a mediation effect between ALE and attenuated positive psychotic positive symptoms when positive psychotic symptoms were grouped together.

CONCLUSIONS

There are probably several possible trajectories leading to the formation of positive psychotic symptoms and the results of the present study reveal that one such trajectory may involve the maladaptive regulation of negative emotions alongside a certain general vulnerability after experiencing ALE.

Can computer-assisted cognitive remediation improve employment and productivity outcomes of patients with severe mental illness? A meta-analysis of prospective controlled trials

BACKGROUND

Computer-assisted cognitive remediation (CACR) has been demonstrated to enhance cognition of patients with severe mental illness (SMI). Patients with improved cognitive skills may find it easier to be employed, and the ability to maintain employment is an important sign of recovery.

AIM

To assess whether CACR is an effective method to enhance work-related outcomes in patients with SMI.

METHOD

Prospective controlled trials evaluating CACR on productivity outcomes were systematically identified from the OVID databases. Employment rates, total days of work in a year, and total annual earnings were defined as the productivity outcomes.

RESULTS

Nine trials were published between 2005 and 2014 and were conducted in the United States, Germany, Italy, Singapore and Japan. A total of 740 patients with mean age of 36.4 years were included. The duration of CACR ranged from 2 months to 2 years, and the patients were followed-up from 1 year to 3 years. Patients receiving CACR showed 20% higher employment rate (95% CI = 5%-35%), worked 19.5 days longer in a year (95% CI = 2.5-36.6 days), and earned US$959 more in total annual earnings (95% CI = US$285 to US$1634) than those not receiving CACR.

CONCLUSION

CACR can enhance productivity outcomes for patients with SMI, including higher employment rate, longer duration of work and higher income. The economic benefit of CACR can enhance the quality of life for patients with SMI, and may reduce financial burden on the health and welfare system. Therefore, CACR can be recommended and incorporated into regular vocational rehabilitation programs.

Metakognitive und sozial-kognitive Defizite bei Schizophrenien. Funktionelle Bedeutung und Behandlungsstrategien

Die Gruppe der Schizophrenien umfasst heterogene psychopathologische Syndrome, die oft mit neurokognitiven Störungen und niedrigem psychosozialen Funktionsniveau assoziiert sind. Empirische Studien legen nahe, dass viele mit Schizophrenie assoziierte Symptome auf Störungen der sozialen Kognition bzw. metakognitive Störungen zurückgeführt werden können. Diese Konzepte beziehen sich auf die Fähigkeit, soziale Signale wahrnehmen und interpretieren, eigene und psychische Zustände Anderer reflektieren und dieses Wissen flexibel in sozialen Interaktionen und zur Problemlösung einsetzen zu können. Der vorliegende Artikel gibt eine Übersicht über sozial-kognitive und metakognitive Defizite bei Schizophrenien und wie über das Training dieser Kernkompetenzen das psychosoziale Funktionsniveau von Patienten mit Schizophrenie verbessert werden kann. Bei Schizophrenien sind soziale Kognition und Metakognition eng mit dem psychosozialen Funktionsniveau verbunden, zum Teil jedoch auch abhängig von neurokognitiven Fähigkeiten. Sozial-kognitives bzw. metakognitives Training kann zur Verbesserung des psychosozialen Funktionsniveaus beitragen, möglicherweise aber in Abhängigkeit vom Lernpotential und der Motivation der Patienten. Zukünftige Studien sollten untersuchen, welche Subtypen innerhalb des Schizophrenie-Spektrums am ehesten von sozial-kognitivem und metakognitivem Training profitieren können und welche Gruppen ggf. zusätzlich neurokognitives Training benötigen, um das psychosoziale Funktionsniveau zu verbessern.

Effectiveness of computerized cognitive rehabilitation training on symptomatological, neuropsychological and work function in patients with schizophrenia

INTRODUCTION

There has been plenty of interest in cognitive rehabilitation for schizophrenia here in Korea since the year 2000. But the efficacy studies of cognitive remediation intervention are still deficient. The primary purpose of this study was to develop a computer-assisted cognitive remediation program and conduct a clinical trial in a group of schizophrenic patients.

METHODS

Sixty patients with schizophrenia were randomly assigned to a computerized cognitive rehabilitation (Cog-trainer) group plus usual rehabilitation (UR) or to a usual rehabilitation (UR) group only. Clinical, neuropsychological and functional outcome variables were assessed at baseline and after intervention. The Cog-trainer group received 20 sessions of computerized cognitive remediation training over 3 months. This training program consists of 10 units, with each unit being divided into three stages: (i) practice; (ii) application; and (iii) advanced.

RESULTS

Compared to the UR group, the Cog-trainer exhibited a significant improvement in attention, concentration and working memory. The Cog-trainer group also showed improvement in the work quality subscale of the work behavior inventory. However, there were no significant benefits of computerized cognitive remediation where symptoms were concerned.

DISCUSSION

These results indicate that computerized cognitive rehabilitation training can contribute to an improvement in the cognitive function of people with schizophrenia. The changes in cognitive outcomes can also contribute to improvement in job functioning. Further study of generalization to other functional outcome measures will be necessary. Long-term follow-up studies are needed to confirm the maintenance of such improvements.

Current trends in the empirical study of cognitive remediation for schizophrenia

Cognitive remediation (CR) for schizophrenia is a learning-based behavioural skills training intervention designed to enhance neuro and (or) social cognitive skills, with the ultimate goal of generalization to improve psychosocial outcomes. This review summarizes conceptual approaches to CR for schizophrenia and the evidence for efficacy in clinical research settings. Four issues are at the forefront of ongoing research: the identification of techniques that produce the largest cognitive change, delineation of techniques that enhance transfer of cognitive skills to functional skills, the identification of CR methods that can be personalized to meet the specific cognitive and functional needs of each individual, and, all the while, ensuring that when CR methods are developed in a research setting, they remain scalable for delivery in the larger clinical community. In response to these issues, 3 prominent research trends have emerged: the rise of a new generation of computerized restorative cognitive training, the integration of CR with skills training to promote generalization, and the application of techniques to enhance motivation and learning during CR. As data on the neural basis of learning in people with schizophrenia become available, new technologies that harness the ability of the brain to make sustainable, functional changes may be integrated within a therapeutic context that promotes a personalized approach to learning. The development of transportable and scalable methods of CR that maximize the ability of people with schizophrenia to improve cognition will help them achieve personal goals for recovery.

Potential therapeutic avenues to tackle social cognition problems in schizophrenia

Therapeutic strategies for improving social cognition in patients with schizophrenia have shown much promise in improving social functioning, as well as remediating core psychotic symptoms. However, the efficacy of previous interventions has often been limited by the ambiguity and inconsistency of the categorized subdomains of social cognition, including theory of mind, emotion processing, social perception and attributional bias. Recent research in social and cognitive neuroscience has revealed many new issues that could contribute to the development of more integrated approaches for improving social functioning. The application of such neuroscientific work to a therapeutic and diagnostic context is likely to encourage more effective transference of learned skills to real-world social functioning. This article seeks to provide a comprehensive review of previous social cognitive interventions for schizophrenia, highlight some crucial limitations of these and present the relevance of recent advances in neuroscientific research in possible future treatment strategies. It is emphasized that a more integrated and naturalistic approach for improving social functioning with greater sensitivity for neuroscientific findings related to the psychopathology of schizophrenia is warranted.

A brief cognitive assessment tool for schizophrenia: construction of a tool for clinicians

Cognitive impairment in schizophrenia is often severe, enduring, and contributes significantly to chronic disability. But clinicians have difficulty in assessing cognition due to a lack of brief instruments. We evaluated whether a brief battery of cognitive tests derived from larger batteries could generate a summary score representing global cognitive function. Using data from 3 previously published trials, we calculated the corrected item-total correlations (CITCs) or the correlation of each test with the battery total score. We computed the proportion of variance that each test shares with the global score excluding that test (R(t)(2)=CITC(2)) and the variance explained per minute of administration time for each test (R(t)(2)/min). The 3 tests with the highest R(t)(2)/min were selected for the brief battery. The composite score from the trail making test B, category fluency, and digit symbol correlated .86 with the global score of the larger battery in 2 of the studies and correlated between .73 and .82 with the total battery scores excluding these 3 tests. A Brief Cognitive Assessment Tool for Schizophrenia (B-CATS) using the above 3 tests can be administered in 10-11 min. The full batteries of the larger studies have administration times ranging from 90 to 210 min. Given prior research suggesting that a single factor of global cognition best explains the pattern of cognitive deficit in schizophrenia, an instrument like B-CATS can provide clinicians with meaningful data regarding their patients' cognitive function. It can also serve researchers who want an estimate of global cognitive function without requiring a full neuropsychological battery.

Cognitive training plus a comprehensive psychosocial programme (OPUS) versus the comprehensive psychosocial programme alone for patients with first-episode schizophrenia (the NEUROCOM trial): a study protocol for a centrally randomised, observer-blinded multi-centre clinical trial

Background

Up to 85% of patients with schizophrenia demonstrate cognitive dysfunction in at least one domain. Cognitive dysfunction plays a major role in functional outcome. It is hypothesized that addition of cognitive training to a comprehensive psychosocial programme (OPUS) enhances both cognitive and everyday functional capacity of patients more than the comprehensive psychosocial programme alone.

Methods

The NEUROCOM trial examines the effect on cognitive functioning and everyday functional capacity of patients with schizophrenia of a 16-week manualised programme of individual cognitive training integrated in a comprehensive psychosocial programme versus the comprehensive psychosocial programme alone. The cognitive training consists of four modules focusing on attention, executive functioning, learning, and memory. Cognitive training involves computer-assisted training tasks as well as practical everyday tasks and calendar training. It takes place twice a week, and every other week the patient and trainer engage in a dialogue on the patient's cognitive difficulties, motivational goals, and progress in competence level. Cognitive training relies on errorless learning principles, scaffolding, and verbalisation in its effort to improve cognitive abilities and teach patients how to apply compensation strategies as well as structured problem solving techniques. At 16-week post-training and at ten-months follow-up, assessments are conducted to investigate immediate outcome and possible long-term effects of cognitive training. We conduct blinded assessments of cognition, everyday functional capacity and associations with the labour market, symptom severity, and self-esteem.

Discussion

Results from four-month and ten-month follow-ups have the potential of reliably providing documentation of the long-term effect of CT for patients with schizophrenia.

Efficacy and specificity of computer-assisted cognitive remediation in schizophrenia: a meta-analytical study

BACKGROUND

Cognitive remediation is frequently based on computerized training methods that target different cognitive deficits. The aim of this article was to assess the efficacy of computer-assisted cognitive remediation (CACR) in schizophrenia and to determine whether CACR enables selective treatment of specific cognitive domains.

METHOD

A meta-analysis was performed on 16 randomized controlled trials evaluating CACR. The effect sizes of differences between CACR and control groups were computed and classified according to the cognitive domain assessed. The possible influences of four potential moderator variables were examined: participants' age, treatment duration, weekly frequency, and control condition type. To test the domain-specific effect, the intended goal of each study was determined and the effect sizes were sorted accordingly. The effect sizes of the cognitive domains explicitly targeted by the interventions were then compared with those that were not.

RESULTS

CACR enhanced general cognition with a mean effect size of 0.38 [confidence interval (CI) 0.20-0.55]. A significant medium effect size of 0.64 (CI 0.29-0.99) was found for Social Cognition. Improvements were also significant in Verbal Memory, Working Memory, Attention/Vigilance and Speed of Processing with small effect sizes. Cognitive domains that were specifically targeted by the interventions did not yield higher effects than those that were not.

CONCLUSIONS

The results lend support to the efficacy of CACR with particular emphasis on Social Cognition. The difficulty in targeting specific domains suggests a 'non-specific' effect of CACR. These results are discussed in the light of the possible bias in remediation tasks due to computer interface design paradigms.

Executive function needs to be targeted to improve social functioning with Cognitive Remediation Therapy (CRT) in schizophrenia

While the role of impaired cognition in accounting for functional outcome in schizophrenia is generally established, the relationship between cognitive and functional change in the context of treatments is far from clear. The current paper tries to identify which cognitive changes lead to improvements in daily functioning among persons with chronic schizophrenia who had current negative symptoms and evidenced neuropsychological impairments. In a previous work, Cognitive Remediation Therapy (CRT) was compared with a control therapy, involving similar length of therapist contact but different targets. At the end of treatment, CRT conferred a benefit to people with schizophrenia in cognition and functioning [Schizophrenia Research, 87 (2006) 323-331]. Subsequently, analyses of covariance (ANCOVA) were conducted with baseline and cognitive change scores as covariates to test whether cognitive change predicted change in functioning. Additionally, statistical tests to establish the mediation path with significant variables were performed. Although verbal memory, but not executive functioning, was associated with functioning at baseline, it was the improvement in executive functioning that predicted improved daily functioning. Verbal memory played a mediator role in the change process. Consequently, in order to improve daily functioning with CRT, executive function still needs to be targeted in despite of multiple cognitive impairments being present.

Computer-aided neurocognitive remediation as an enhancing strategy for schizophrenia rehabilitation

Cognitive dysfunction is a chronically disabling feature of schizophrenia, associated with limits in obtaining rehabilitation improvements. The purpose of this study is to assess the effectiveness of intensive computer-aided cognitive remediation treatment (CRT) added to a standard rehabilitation treatment (SRT), in enhancing neuropsychological performances and daily functioning in patients with schizophrenia. A 12-week, randomized, controlled, single-blind trial of neurocognitive remediation was carried out on 86 patients with clinically stabilized DSM-IV schizophrenia. Patients were assessed on cognitive and daily functioning before and after either CRT or placebo training that had been added to their SRT. After 3 months the repeated measure ANOVA showed a significant time x treatment interaction for executive function and attention performances and in daily functioning assessment in favour of patients in the SRT+CRT treatment. Results confirmed that cognitive remediation added to the SRT of schizophrenia enhanced its neuropsychological effects and increased the effects of a long-term rehabilitation programme in terms of functional outcomes.

Effects of cognitive remediation therapies on psychotic symptoms and cognitive complaints in patients with schizophrenia and related disorders: a randomized study

BACKGROUND

Cognitive remediation therapy (CRT) has proven to be effective in treating cognitive deficits in schizophrenia. The current study aimed to assess the efficacy of CRT on psychotic symptoms and cognitive complaints.

METHODS

We contrasted the changes in symptoms and cognitive complaints in patients with schizophrenia and related disorders who received 2 novel CRTs, one targeting mental state attribution, and the other, mental flexibility, compared with a control group given treatment as usual. Twenty-four patients with schizophrenia and related disorders were pseudo-randomly assigned to 1 of 3 groups. Psychotic symptoms and subjective complaints about their cognitive deficits were evaluated twice in each group, before and after therapy. Scores obtained pre- and post-therapy were compared between the groups.

RESULTS

The therapies were well-tolerated by the participants, and no one dropped out of the study. Symptoms decreased after therapy, but not in the control group. The mental flexibility group showed the most improvement. Moreover, patients in this group described a subjective diminution of their cognitive deficits.

CONCLUSIONS

Our results demonstrate that CRT can be useful to reduce clinical symptoms while they suggest an impact of CRT on cognitive complaints in patients with schizophrenia.

Schizophrenia: genetics, prevention and rehabilitation

OBJECTIVE

Genetic factors are largely implicated in predisposing to schizophrenia. Environmental factors contribute to the onset of the disorder in individuals at increased genetic risk. Cognitive deficits have emerged as endophenotypes and potential therapeutic targets for schizophrenia because of their association with functional outcome. The aims of this review were to analyse the joint effect of genetic and environmental (G×E) factors on liability to schizophrenia and to investigate relationships between genes and cognitive endophenotypes focusing on practical applications for prevention and rehabilitation.

METHODS

Medline search of relevant studies published between 1990 and 2008.

RESULTS

In schizophrenia, examples of G×E interaction include the catechol-O-methyl transferase (COMT) (Val158Met) polymorphism, which was found to moderate the onset of psychotic manifestations in response to stress and to increase the risk for psychosis related to cannabis use, and neurodevelopmental genes such as AKT1 (serine-threonine kinase), brain-derived neurotrophic factor (BDNF), DTNBP1 (dysbindin) and GRM3 (metabotropic glutamate receptor 3), which were associated with development of schizophrenia in adulthood after exposure to perinatal obstetric complications. Neurocognitive deficits are recognised as core features of schizophrenia that facilitate the onset of the disorder and have a great impact on functional outcome. Neurocognitive deficits are also endophenotypes that have been linked to a variety of genes [COMT, neuregulin (NRG1), BDNF, Disrupted-In-Schizophrenia 1 (DISC1) and dysbindin] conferring susceptibility to schizophrenia. Recently, it has emerged that cognitive improvement during rehabilitation therapy was under control of COMT (Val158Met) polymorphism.

CONCLUSION

This review could indicate a pivotal role of psychiatric genetics in prevention and rehabilitation of schizophrenic psychoses.

[Effectiveness of Integrated Psychological Therapy for schizophrenia patients. A meta-analysis including 28 independent studies]

Over the past 24 years, research groups in eight different countries have conducted 28 independent evaluation studies on Integrated Psychological Therapy (IPT) including 1,329 schizophrenia patients. The present study examines the effectiveness of IPT under different treatment conditions by means of a meta-analytic review. The most salient results indicate favourable mean effect sizes for IPT in comparison to control groups (placebo-attention conditions, standard care). Moreover, the superiority of IPT continues to increase during an average catamnestic phase of 8.1 months. The method obtains similarly favourable effects in different functional areas (neurocognition, social behaviour, psychopathology) and different assessment formats (expert ratings, self-reports, psychological tests). The comparison of different settings of IPT and control groups shows the superiority of IPT in any given therapy or site condition. The analysis of subsamples of inpatients, outpatients, and patients in varying rehabilitation phases reveals similarly favourable effects. Comparing only high-quality studies yields comparable results. In summary, the present meta-analysis corroborates evidence that IPT is an 'empirically validated treatment' according to American Psychiatric Association guidelines.

Rehabilitation and recovery in schizophrenia

The combination of new medications and effective psychosocial rehabilitation interventions has the potential to improve outcomes for individuals with schizophrenia significantly. Patients who have persistent positive symptoms can benefit from cognitive behavior therapy. Impairments in social competence can be addressed with social skills training. Supported employment programs may increase the ability of patients who have schizophrenia to obtain competitive employment. Family psychoeducational approaches, treatments for comorbid substance abuse, and cognitive rehabilitation approaches that enhance or bypass impairments in cognitive functioning are discussed. This article describes current efforts to incorporate these evidence-based principles of rehabilitative medicine into the management of schizophrenia.

Computer-assisted cognitive remediation in schizophrenia: what is the active ingredient?

An emerging body of research has shown that computer-assisted cognitive remediation, consisting of training in attention, memory, language and/or problem-solving, produces improvement in neurocognitive function that generalizes to untrained neurocognitive tests and may also impact symptoms and work functioning in patients with schizophrenia. The active ingredient of these interventions, however, remains unknown as control groups in these studies have typically included few, if any, of the elements of these complex behavioral treatments. This study compared the effects of an extended (12-month), standardized, computer-assisted cognitive remediation intervention with those of a computer-skills training control condition that consisted of many of the elements of the experimental intervention, including hours spent on a computer, interaction with a clinician and non-specific cognitive stimulation. Forty-two patients with schizophrenia were randomly assigned to one of two conditions and were assessed with a comprehensive neuropsychological test battery before and after treatment. Results revealed that cognitive-remediation training produced a significant improvement in working memory, relative to the computers-skills training control condition, but that there was overall improvement in both groups on measures of working memory, reasoning/executive-function, verbal and spatial episodic memory, and processing speed. Taken together, these findings suggest that specific practice in neurocognitive exercises targeted at attention, memory and language, produce improvements in neurocognitive function that are not solely attributable to non-specific stimulation associated with working with a computer, interacting with a clinician or cognitive challenge, but that non-specific stimulation has a salutary effect on neurocognition as well.

Can cognitive exercises help treat anorexia nervosa?

Cognitive remediation therapy (CRT) is used as an intervention for people with brain lesions and psychosis. This case report demonstrates the possible benefits of introducing CRT into treatment packages for anorexia nervosa (AN). In our previous work, we reported that people with AN demonstrate inflexibility in cognitive set-shifting tasks. Weight gain alone does not improve the neuropsychological profile in set-shifting tasks. This case report illustrates how training programmes can address problems in cognitive rigidity. We acknowledge the limitations of case studies, however, this is a starting point in exploring the possibilities of introducing CRT as part of the treatment of AN.

Anwendung - Effektivität - Aufrechterhaltung

Zusammenfassung. Hintergrund: Die “Effektivität“ psychotherapeutischer Interventionen, für die “Wirksamkeit“ in kontrollierten Studien belegt wurde, hängt in der Versorgungspraxis von zahlreichen Faktoren ab, die bisher meist isoliert diskutiert wurden. Fragestellung: Es soll geklärt werden, ob Fragen zur Wirkung psychotherapeutischer Interventionen heuristisch fruchtbar in formalen Modellen integriert werden können. Methoden: Zur Modellbildung wird dabei die Boolesche Logik verwendet. Die Möglichkeiten dieses Ansatzes werden anhand von Beispielen zur Therapie psychischer Störungen aufgezeigt. Ergebnisse: Die beispielhaften Modelle hilfreicher Interventionen setzen voraus, dass 1. die Intervention aktiviert wird, wenn eine therapeutische Veränderung notwendig ist (Anwendung), dass 2. die Intervention die intendierte Veränderung herbeiführen kann (Effektivität) und dass 3. die erreichte Veränderung nachhaltig ist (Aufrechterhaltung). Schlussfolgerungen: Die vorgestellten “Booleschen Interventionsmodelle“ postulieren spezifische zeitliche Muster (“Attraktoren“) und erlauben eine neuartige vergleichende Analyse von Interventionsformen und Versorgungssystemen.

Impact of intellectual status on response to cognitive task training in patients with schizophrenia

Cognitive remediation is a promising rehabilitation procedure for people with schizophrenia, but very little is known about who can benefit. In the current analyses, we examined the role of pre-morbid and morbid intellectual function in predicting response to cognitive remediation in a sample of 152 patients diagnosed with schizophrenia or schizoaffective disorder. They were participants in a trial of work therapy and cognitive remediation and had been randomized to receive either Neurocognitive Enhancement Therapy with Work Therapy (NET+WT) or Work Therapy only (WT only). For the current analyses, patients were divided into three intellectual subgroups based on their pattern of premorbid and morbid deficits (preserved intelligence, compromised intelligence, and deteriorated intelligence), and their cognitive remediation outcomes were examined. Cognitive remediation response was measured in two ways: normalization of performance on a computerized training task, and pre-post neuropsychological test performance. Subjects in NET+WT showed greater improvement in cognition than those in WT only, but response differed by intellectual group. For patients in the compromised group, those in NET+WT showed a significantly higher proportion of task normalization than those in the WT only condition, but no such differences were found with the preserved and deteriorated intellectual groups. For patients in the preserved and deteriorated intellectual groups, those in the NET+WT condition showed significantly greater improvement in the analysis of pre-post neuropsychological test performance, but this difference was not found in the compromised intellectual group. These findings suggest that the compromised intellectual group, which had the lowest frequency of normal performers at intake, benefited from NET by achieving dramatic increases in normalization, but that they had difficulty in generalizing these gains to untrained tasks. Those in the preserved and deteriorated intellectual groups were more successful in generalizing their training.

Perception of causality in schizophrenia spectrum disorder

Patients with schizophrenia spectrum disorders often maintain deviating views on cause-effect relationships, especially when positive and disorganization symptoms are manifest. Altered perceived causality is prominent in delusional ideation, in ideas of reference, and in the mentalizing ability (theory of mind [ToM]) of patients. Perceiving causal relationships may be understood either as higher order cognitive reasoning or as low-level information processing. In the present study, perception of causality was investigated as a low-level, preattentional capability similar to gestalt-like perceptual organization. Thirty-one patients (24 men and 7 women with mean age 27.7 years) and the same number of healthy control subjects matched to patients with respect to age and sex were tested. A visual paradigm was used in which 2 identical discs move, from opposite sides of a monitor, steadily toward and then past one another. Their coincidence generates an ambiguous, bistable percept (discs either "stream through" or "bounce off" one another). The bouncing perception, ie, perceived causality, is enhanced when auditory stimuli are presented at the time of coincidence. Psychopathology was measured using the Positive and Negative Syndrome Scale. It was found that positive symptoms were strongly associated with increased perceived causality and disorganization with attenuated perceived causality. Patients in general were not significantly different from controls, but symptom subgroups showed specifically altered perceived causality. Perceived causality as a basic preattentional process may contribute to higher order cognitive alterations and ToM deficiencies. It is suggested that cognitive remediation therapy should address both increased and reduced perception of causality.

Integrated psychological therapy (IPT) for schizophrenia: is it effective?

Against the background of evidence-based treatments for schizophrenia, nowadays the implementation of specific cognitive and behavioral interventions becomes more important in the standard care of these patients. Over the past 25 years, research groups in 9 countries have carried out 30 independent evaluations of Integrated Psychological Therapy (IPT), a group program that combines neurocognitive and social cognitive interventions with social skills approaches for schizophrenic patients. The aim of the present study was to evaluate the effectiveness of IPT under varying treatment and research conditions in academic and nonacademic sites. In a first step, all 30 published IPT studies with the participation of 1393 schizophrenic patients were included in the meta-analysis. In a second step, only high-quality studies (HQS) (7 studies including 362 patients) were selected and analyzed to check whether they confirmed the results of the first step. Positive mean effect sizes favoring IPT over control groups (placebo-attention conditions, standard care) were found for all dependent variables, including symptoms, psychosocial functioning, and neurocognition. Moreover, the superiority of IPT continued to increase during an average follow-up period of 8.1 months. IPT obtained similarly favorable effects across the different outcome domains, assessment formats (expert ratings, self-reports, and psychological tests), settings (inpatient vs outpatient and academic vs nonacademic), and phases of treatment (acute vs chronic). The HQS confirmed the results of the complete sample. The analysis indicates that IPT is an effective rehabilitation approach for schizophrenia that is robust across a wide range of patients and treatment conditions.

Efficacy of psychological therapy in schizophrenia: conclusions from meta-analyses

Over the past years, evidence for the efficacy of psychological therapies in schizophrenia has been summarized in a series of meta-analyses. The present contribution aims to provide a descriptive survey of the evidence for the efficacy of psychological therapies as derived from these meta-analyses and to supplement them by selected findings from an own recent meta-analysis. Relevant meta-analyses and randomized controlled trials were identified by searching several electronic databases and by hand searching of reference lists. In order to compare the findings of the existing meta-analyses, the reported effect sizes were extracted and transformed into a uniform effect size measure where possible. For the own meta-analysis, weighted mean effect size differences between comparison groups regarding various types of outcomes were estimated. Their significance was tested by confidence intervals, and heterogeneity tests were applied to examine the consistency of the effects. From the available meta-analyses, social skills training, cognitive remediation, psychoeducational coping-oriented interventions with families and relatives, as well as cognitive behavioral therapy of persistent positive symptoms emerge as effective adjuncts to pharmacotherapy. Social skills training consistently effectuates the acquisition of social skills, cognitive remediation leads to short-term improvements in cognitive functioning, family interventions decrease relapse and hospitalization rates, and cognitive behavioral therapy results in a reduction of positive symptoms. These benefits seem to be accompanied by slight improvements in social functioning. However, open questions remain as to the specific therapeutic ingredients, to the synergistic effects, to the indication, as well as to the generalizability of the findings to routine care.

Cognitive rehabilitation for schizophrenia and the putative role of motivation and expectancies

Cognitive rehabilitation (CR) approaches seek to enhance cognitive processes or to circumvent cognitive impairments in schizophrenia in an effort to improve functional outcome. In this review we examine the research findings on the 8 evidence-based approaches to cognitive remediation listed in the 2005 Training Grid Outlining Best Practices for Recovery and Improved Outcomes for People With Serious Mental Illness, developed by the American Psychological Association Committee for the Advancement of Professional Practice. Though the approaches vary widely in theoretical orientation and methods of intervention, the results are, for the most part, encouraging. Improvements in attention, memory, and executive functioning have been reported. However, many persons with schizophrenia are more impaired in real-world functioning than one would expect given the magnitude of their cognitive deficits. We may need to look beyond cognition to other targets such as motivation to identify the reasons that many persons with schizophrenia demonstrate such marked levels of disability. Although a number of current CR approaches address motivation to varying degrees, treating motivation as a primary target may be needed to maximize CR outcomes.

Effects of a neuropsychological rehabilitation programme on schizophrenic patients' subjective perception of improvement

Cognitive and neuropsychological deficits have long been recognised as part of the schizophrenic syndrome. As these deficits persist after acute psychosis subsides and contribute to the social and occupational difficulties often experienced by individuals with schizophrenia, researchers have begun to consider the applicability of neuropsychological rehabilitation techniques to the treatment of schizophrenic neuropsychological deficits. Although the effectiveness of cognitive rehabilitation programmes in schizophrenia has been addressed, no attention has been afforded to whether the trained patient perceives improvement of the cognitive processes instructed. The present study utilised a treatment versus control group comparison design to evaluate the effect of a neuropsychological rehabilitation programme on the perception of improvement both in schizophrenic patients and their therapists. Twenty-four participants diagnosed with schizophrenia participated in the study. One half of the sample was trained by means of Attention Process Training (APT) and the rest of the patients comprised the control group. No significant differences in perception of improvement were found between treatment and control group, and trained patients found the APT more useful than did their therapists.

The effect of verbalization strategy on Wisconsin Card Sorting Test performance in schizophrenic patients receiving classical or atypical antipsychotics

BACKGROUND

A number of reports showed en encouraging remediation in some patients' executive deficits thanks to the use of 'information processing strategies'. Moreover the impact of antipsychotics on cognitive functions of the schizophrenics is an important issue, especially if an integrated psychosocial treatment is needed. The aim of this paper is to evaluate different executive performance and response to verbalization, a strategy of the Wisconsin Card Sorting Test (WCST) remediation, in subjects on classical vs atypical antipsychotic (AP) treatment.

METHODS

Sixty-three schizophrenic subjects undertook the WCST under standard and modified (verbalization) administration. Subjects were stratified by the kind of WCST response (i.e. good, poor and remediable) and AP treatment (i.e. atypical vs. classical).

RESULTS

Subjects on atypical APs showed a better performance than those on classical ones. More poor performers who did not remediate were seen in the sample with classical Aps while subjects who remediated the performance were seen in the subgroup with atypical APs only. An increase of perseverative and total errors was seen in poor performers subjects on classical APs.

CONCLUSION

Subjects on atypicals showed a better cognitive pattern in terms of WCST performance. Since the naturalistic assignment of medication we cannot draw conclusions about its effect on cognitive performance and its interaction with cognitive remediation potential. However the data lead us to hypothesize that subjects with potential room for remediation did so with the atypical APs.

Evidence-based psychotherapy for schizophrenia

Many patients with schizophrenia have psychological distress and receive some form of psychotherapy. Several different psychotherapeutic approaches for schizophrenia have been developed and studied. Of these approaches, cognitive behavior therapy has the strongest evidence base and has shown benefit for symptom reduction in outpatients with residual symptoms. In addition to cognitive behavior therapy, other approaches include compliance therapy, personal therapy, acceptance and commitment therapy, and supportive therapy. Although usually studied as distinct approaches, the therapies overlap with each other in their therapeutic elements. As psychotherapy for schizophrenia further evolves, it will likely be informed by other psychosocial interventions used with this clinical population. In particular, techniques of remediating cognitive deficits, teaching behavioral skills, and educating about schizophrenia may be incorporated with psychotherapy. Future research may also consider three different goals of psychotherapy with this population: to provide emotional support, to enhance skills for functional recovery, and to alter the underlying illness process.
