Feasibility and acceptability of brief cognitive remediation targeting metacognition in acute inpatients with psychosis: a case series

Ecological virtual reality-based cognitive remediation among inpatients with schizophrenia: A pilot study

Schizophrenia presents a considerable clinical challenge due to limited progress in promoting daily-life functioning among diagnosed individuals. Although cognitive remediation (CR) has emerged as a promising approach to improving cognitive and functional outcomes in schizophrenia, its effectiveness among inpatients and within hospital environments-where opportunities to practice skills in real-world contexts are limited-remains unclear. Here, we aimed to establish the feasibility and initial efficacy of a short, ecological virtual reality-based CR training (CR-EVR) in acute mental health inpatient settings. Efficacy was assessed at four levels: training engagement, near transfer, far transfer, and ecological transfer. Twenty-three inpatients with schizophrenia (Male: 33.3 ± 8.5; 4 Female) completed 8, 20-min CR-EVR sessions, with exercises training the cognitive abilities of inhibition, planning, working memory, shifting, self-initiation, persistence, and attention. Their cognitive functioning, schizophrenia symptoms, functional capacity, and participation in occupations were evaluated pre- and post-training to address four levels of effectiveness. Of the recruited participants, 25.8 % dropped out. Inpatients who completed the full protocol reported high rates of satisfaction (1-not satisfied; 5-very satisfied)) from the intervention (Median = 4, IQR:3.5-5). Post-training, significant improvements were found in the trained cognitive components (intervention engagement: -6.58 < t/Z < 2.02, p < .05), general cognitive functioning (-2.59 < t/Z < 2.29, p < .05), functional capacity (t = -2.9, p < .05), and diversity of participation in everyday activities (t = -3.36, p < .05). This preliminary study suggests that CR-EVR may be a feasible and practical tool to enhance cognitive and ecological outcomes in short-stay acute inpatient settings. Subject to further research, such intervention may be considered an add-on to current practices that promote recovery and health among inpatient populations.

Cognitive Remediation and Social Recovery in Early Psychosis (CReSt-R): protocol for a pilot randomised controlled study

BACKGROUND

Psychosis, even in its early stages, is associated with significant disability, causing it to be ranked ahead of paraplegia and blindness in those aged 18-35 in terms of years lived with disability. Current pharmacological and psychological interventions intervention have focused primarily on the reduction of positive symptoms (hallucinations and delusions), with little benefit to domains of psychosis such as cognitive difficulties and social and occupational functioning.

METHODS/DESIGN

The CReSt-R intervention trial is a single center, pilot randomised controlled study based at the National University of Ireland (NUI), Galway. The trial will recruit participants from four clinical sites with assessment and intervention completed by the primary NUI Galway team. The trial will explore the feasibility, acceptability, and effectiveness of a novel psychosocial intervention for early psychosis based on a combined cognitive remediation training and cognitive behavioural therapy approach focused on social recovery. Participants, aged 16-35 within the first 5 years of a diagnosed psychotic disorder, will be recruited from the Children and Adolescent Mental Health Service and the Adult Mental Health Services in the region.

DISCUSSION

Cognitive remediation training (for improving cognition) and social recovery focused cognitive behavioural therapy, have both separately demonstrated effectiveness. This trial will evaluate the feasibility, acceptability, and explore the efficacy of a treatment approach that combines both approaches as part of an integrated, multicomponent intervention.

Feasibility and acceptability of the multicontext approach for individuals with acquired brain injury in acute inpatient rehabilitation: A single case series

The Multicontext (MC) approach, a metacognitive intervention designed to improve awareness, strategy use, and executive functioning, may be beneficial for individuals with acquired brain injury (ABI) undergoing acute inpatient rehabilitation. The goal of this study was to provide evidence of feasibility and acceptability of the MC approach and to explore clinical outcomes. A case series of eight individuals with acquired brain injury and at least mild executive functioning impairment were recruited from an acute inpatient rehabilitation unit. The MC approach - involving guided questioning and patient self-generation of strategies practiced across everyday functional cognitive tasks - was implemented within routine occupational therapy. Occupational therapists implemented the MC approach with high adherence to the treatment protocol. Therapists' perceived challenges were the time constraints of inpatient rehabilitation as well as client factors. Participants rated the MC approach as highly satisfying and engaging. They described subjective improvements in their ability to use executive functioning strategies. The MC approach was associated with improvement in awareness, strategy use, and executive functioning at the conclusion of treatment. The MC approach may be a beneficial intervention for individuals with acquired brain injury and executive dysfunction undergoing acute inpatient rehabilitation. Further evaluation with larger samples in controlled trials is warranted.Trial registration: ClinicalTrials.gov identifier: NCT04363645..

Cognitive remediation for inpatients with psychosis: a systematic review and meta-analysis

Cognitive difficulties are common in people with psychosis and associated with considerable disability. Cognitive remediation (CR) can reduce the burden of cognitive difficulties and improve functioning. While mental health care has predominantly shifted to the community, people with greater illness severity and complexity, and those with poor response to treatment and concomitant greater cognitive difficulties, continue to receive inpatient care. The aim of this study is to review and evaluate the acceptability and efficacy of CR for inpatients with psychosis. A systematic search was used to identify randomized controlled trials of CR for inpatients with psychosis. Demographic and clinical information was extracted by independent raters together with therapy outcomes. Study quality was assessed using the Cochrane Collaboration Risk of Bias Assessment tool. Standardized mean change for cognitive and functional outcomes was calculated using Hedges's g and used to infer therapy effects with meta-analysis. Twenty studies were identified considering 1509 participants. Results from random-effect models suggested that CR was effective in improving processing speed (g = 0.48), memory (g = 0.48) and working memory (g = 0.56). While there was an indication of improvements in the levels of vocational, social and global functioning, these were less reliable. On average, 7% of participants dropped-out of treatment. Studies methodological quality was moderate. CR is an acceptable intervention for inpatients with psychosis and can lead to significant cognitive improvements. Evidence for improvement in functioning requires more robust and converging evidence. Future research should extend the evaluation of inpatient CR to subsequent post-discharge community functioning and further need for care.

The Efficacy, Feasibility And Acceptability Of A Remotely Accessible Use Of CIRCuiTS, A Computerized Cognitive Remediation Therapy Program For Schizophrenia: A Pilot Study

INTRODUCTION

The Computerized Interactive Remediation of Cognition - Training for Schizophrenia (CIRCuiTS) is a form of cognitive remediation therapy developed to target neurocognitive and metacognitive deficits of people with schizophrenia, which have a detrimental impact on real-life functioning. The English version of CIRCuiTS demonstrated good acceptability and feasibility. A recent randomized controlled trial provided evidence that the program improves memory and functioning, and that the impact on functional outcome is mediated by metacognition. The next steps in the development of CIRCuiTS include both: 1) the translation and adaptation of the program in different cultural settings; and 2) the demonstration of feasibility, acceptability and effectiveness of a standardized method to administer CIRCuiTS remotely.

PURPOSE

To implement the CIRCuiTS Italian version and to assess acceptability, feasibility and efficacy of a standardized method to administer CIRCuiTS remotely.

METHODS

Participants were assessed at baseline and received up to 40 CIRCuiTS therapy sessions, three times a week, for about 1 hr over a three-month period. Participants were reassessed post-treatment.

RESULTS

The program demonstrated good feasibility and high acceptability when assessed by the number of dropouts and evaluation of patients' satisfaction. Participants improved in learning, speed of processing, working memory and executive control. They showed a reduction in disorganization and improvement in self-esteem, functional capacity, and real-life functioning.

CONCLUSION

In this study, a standardized protocol for using CIRCuiTS from home was implemented. The first set of data showed in the paper is encouraging. The proposed procedure could lead to a dropout reduction while maintaining the efficacy of the program.

The nuts and bolts of Cognitive Remediation: Exploring how different training components relate to cognitive and functional gains

BACKGROUND

Cognitive Remediation (CR) is an evidence based treatment targeting cognitive and functional difficulties in people with psychosis. Despite the large number of effectiveness studies, only limited evidence exists for the active ingredients of this therapy. This study begins to fill this gap by exploring the relationship between CR ingredients, including alliance with a therapist, and therapy outcomes.

METHOD

This is a secondary analysis based on data from a published randomised controlled trial comparing CR+treatment-as-usual (TAU) to TAU alone. We considered the association between CR active ingredients including errorless learning, massed practice, strategy use and therapeutic alliance on the cognitive, functioning and symptom outcomes that significantly improved following therapy.

RESULTS

Forty-six of the 96 participants were randomised to CR. After therapy the CR group showed significant improvement in non-verbal memory, functioning and approaching significance, improvements in executive functions. All therapy ingredients were inter-related but strategy use alone was associated therapeutic alliance. Cognitive improvements were associated with massed practice, number of useful strategies and therapeutic alliance, but improvements in functioning were associated only with therapeutic alliance.

CONCLUSIONS

These findings build the evidence base for the usefulness of specific therapy components. As for other psychological therapies it appears that therapeutic alliance may be an important factor in driving change for key CR outcomes, particularly functioning, in people with psychosis.

Computerized cognitive training is associated with improved psychosocial treatment engagement in schizophrenia

Poor treatment engagement is an enduring problem in the care of patients with schizophrenia. Evidence suggests that targeted cognitive training (TCT) improves cognition and functional outcomes, but this time-consuming intervention might reduce patients' engagement in other treatment activities when implemented in real-world settings. This is especially true of residential care programs which encourage patients to engage in group therapies, self-care, and a wide variety of structured social, work, and other rehabilitation activities. This study aimed to determine whether TCT negatively impacts engagement in other psychosocial treatments. Patients with schizophrenia were recruited from a community-based residential care program and randomized to one of two intervention arms: treatment as usual (TAU; n = 22) or TAU augmented with TCT (n = 24). Psychosocial treatment engagement was tracked over 20 weeks. Treatment groups did not significantly differ on baseline variables or psychosocial treatment engagement in the 5 weeks prior to randomization. TCT had a positive effect on engagement (β = 0.112, p = 0.003), but there was no treatment-by-time interaction (β = -0.029, p = 0.672). Participants in TCT engaged in an average of 1.34 additional group therapies, 0.58 additional activities of daily living, and 0.84 additional rehabilitation activities per week in comparison to TAU participants. Baseline cognition was also a significant predictor of psychosocial treatment engagement. Overall, results suggest that TCT can be implemented in real-world settings without negatively impacting engagement in other psychosocial treatments. Additional studies are needed to determine what role nonspecific factors play in the positive impact of TCT.
