Implementation and Outcomes of a Collaborative Multi-Center Network Aimed at Web-Based Cognitive Training - COGWEB Network

International Experience of Implementing Cognitive Remediation for People With Psychotic Disorders

BACKGROUND

Cognitive remediation (CR) is an effective therapy for the cognitive impact of mental illness, especially schizophrenia. Global efforts are being made to implement CR into routine mental health services with the aim of improving functional outcomes for the population of people recovering from mental illness. Implementation and dissemination of CR in heterogeneous settings require knowledge gleaned from formal implementation research and pragmatic experiential learning. This article describes cross-cultural approaches to CR implementation, focusing on initiatives in France, the United States, Australia, and Japan.

METHOD

Key leaders in the implementation of CR in France, the United States, Australia, and Japan were asked to describe the implementation and dissemination process in their settings with respect to the categories of context, implementation, outcomes, facilitators, and barriers.

RESULTS

All 4 sites noted the role of collaboration to leverage the implementation of CR into mental health rehabilitation services. In France, high-level, government organizational backing enhanced the dissemination of CR. Academic and clinical service partnerships in the United States facilitated the dissemination of programs. The advocacy from service users, families, and carers can aid implementation. The support from international experts in the field can assist in initiating programs but maintenance and dissemination require ongoing training and supervision of staff.

CONCLUSIONS

CR is an effective intervention for the cognitive impact of schizophrenia. Programs can be implemented in diverse settings globally. Adaptations of CR centering upon the core components of effective CR therapy enhance outcomes and enable programs to integrate into diverse settings.

A comparison of two personalization and adaptive cognitive rehabilitation approaches: a randomized controlled trial with chronic stroke patients

BACKGROUND

Paper-and-pencil tasks are still widely used for cognitive rehabilitation despite the proliferation of new computer-based methods, like VR-based simulations of ADL's. Studies have established construct validity of VR assessment tools with their paper-and-pencil version by demonstrating significant associations with their traditional construct-driven measures. However, VR rehabilitation intervention tools are mostly developed to include mechanisms such as personalization and adaptation, elements that are disregarded in their paper-and-pencil counterparts, which is a strong limitation of comparison studies. Here we compare the clinical impact of a personalized and adapted paper-and-pencil training and a content equivalent and more ecologically valid VR-based ADL's simulation.

METHODS

We have performed a trial with 36 stroke patients comparing Reh@City v2.0 (adaptive cognitive training through everyday tasks VR simulations) with Task Generator (TG: content equivalent and adaptive paper-and-pencil training). The intervention comprised 12 sessions, with a neuropsychological assessment pre, post-intervention and follow-up, having as primary outcomes: general cognitive functioning (assessed by the Montreal Cognitive Assessment - MoCA), attention, memory, executive functions and language specific domains.

RESULTS

A within-group analysis revealed that the Reh@City v2.0 improved general cognitive functioning, attention, visuospatial ability and executive functions. These improvements generalized to verbal memory, processing speed and self-perceived cognitive deficits specific assessments. TG only improved in orientation domain on the MoCA, and specific processing speed and verbal memory outcomes. However, at follow-up, processing speed and verbal memory improvements were maintained, and a new one was revealed in language. A between-groups analysis revealed Reh@City v2.0 superiority in general cognitive functioning, visuospatial ability, and executive functions on the MoCA.

CONCLUSIONS

The Reh@City v2.0 intervention with higher ecological validity revealed higher effectiveness with improvements in different cognitive domains and self-perceived cognitive deficits in everyday life, and the TG intervention retained fewer cognitive gains for longer.

TRIAL REGISTRATION

The trial is registered at ClinicalTrials.gov, number NCT02857803. Registered 5 August 2016, .

Capturing Expert Knowledge for the Personalization of Cognitive Rehabilitation: Study Combining Computational Modeling and a Participatory Design Strategy

Background

Cognitive impairments after stroke are not always given sufficient attention despite the critical limitations they impose on activities of daily living (ADLs). Although there is substantial evidence on cognitive rehabilitation benefits, its implementation is limited because of time and human resource’s demands. Moreover, many cognitive rehabilitation interventions lack a robust theoretical framework in the selection of paper-and-pencil tasks by the clinicians. In this endeavor, it would be useful to have a tool that could generate standardized paper-and-pencil tasks, parameterized according to patients' needs.

Objective

In this study, we aimed to present a framework for the creation of personalized cognitive rehabilitation tasks based on a participatory design strategy.

Methods

We selected 11 paper-and-pencil tasks from standard clinical practice and parameterized them with multiple configurations. A total of 67 tasks were assessed according to their cognitive demands (attention, memory, language, and executive functions) and overall difficulty by 20 rehabilitation professionals.

Results

After assessing the internal consistency of the data—that is, alpha values from .918 to .997—we identified the parameters that significantly affected cognitive functions and proposed specific models for each task. Through computational modeling, we operationalized the tasks into their intrinsic parameters and developed a Web tool that generates personalized paper-and-pencil tasks—the Task Generator (TG).

Conclusions

Our framework proposes an objective and quantitative personalization strategy tailored to each patient in multiple cognitive domains (attention, memory, language, and executive functions) derived from expert knowledge and materialized in the TG app, a cognitive rehabilitation Web tool.

Adherence to a Low-Support Cognitive Remediation Training Program for Psychosis

Cognitive remediation (CR) has emerged as the treatment of choice for impaired cognition in psychosis. However, little is known about adherence rates and factors predicting adherence to CR, particularly in clinical settings where high-level therapist support is unavailable. This study aimed to establish adherence rates and examine variables predicting adherence to a computerized CR program for psychosis (with minimal support). Patients with psychosis (n = 61) participated in an 8-week CR program. Results showed 46% completed a meaningful amount of CR training. The fully adherent (>80% of the prescribed amount) and nonadherent groups differed where adherent participants had poorer working-memory and higher negative symptom scores. These findings suggest that approximately half of the sample were adherent to treatment despite minimal therapist support. Furthermore, higher cognitive deficits and negative symptoms did not impede adherence, and may have contributed to patients' motivation to complete the program.
