Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Adults with serious mental illnesses (such as schizophrenia and schizoaffective disorders) often experience a range of cognitive difficulties (such as memory, problem solving difficulties) that affect their ability to lead meaningful life roles. Cognitive remediation is an intervention to address cognitive difficulties in this group of mental health service users. Its implementation in less well-resourced community-based settings is less well-studied.

Therefore, the aims of the study are:

* To investigate the effects of cognitive remediation on various cognitive skills (such as attention, memory, problem-solving, facial expression recognition, taking others' perspectives etc), for participants with schizophrenia or schizoaffective disorders in community mental health settings.
* To investigate if factors such as participants' motivation for engagement and social interaction can affect changes in cognitive skills and functional ability.

Participants in the treatment group will attend computer-based cognitive exercises to improve their cognitive skills. They will also participate in group sessions facilitated by therapists to learn how to utilize strategies learned from the computer sessions in their daily lives. Participants in the control group will attend the usual rehabilitation activities in their respective community-based psychiatric rehabilitation centers.

This research study will compare the differences in their cognitive performance, functional ability and recovery immediately after the intervention and 8 weeks later.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Persons with severe mental illness such as schizophrenia and schizoaffective disorders often have difficulties integrating back to the community and many face the prospect of long-term institutionalisation when families could not manage them. It is assumed that their inability to function is due to their mood and psychotic symptoms such as auditory hallucinations and persecutory delusions and paranoid thoughts. However, evidence has shown that neurocognitive impairment (such as information processing, memory, problem solving) coupled with social cognitive problems (such as difficulty with emotion recognition, perspective taking etc) are the ones with more long-term impact on their functioning (Green et.al., 2000; Tan, 2009).

Cognitive remediation is a form of intervention that addresses cognitive impairments of persons with psychiatric conditions, in order to improve real-world functioning. There are several approaches to cognitive remediation. One of the well-studied cognitive remediation programmes is the Neuropsychological and Educational Approach to Remediation (NEAR), which consists of computer-assisted cognitive exercises, followed by bridging sessions to generalise strategies learnt to daily living. NEAR is conducted in groups of 5-8 clients and is facilitated by 1-2 therapists (Medalia, Revheim and Herlands, 2009). It uses drill-and-practice rehearsal method to improve discrete cognitive skills, as well as strategy-learning method to equip clients with strategies to overcome cognitive challenges in different functional scenarios. NEAR has been implemented in inpatient wards, supported housing settings and outpatient rehabilitation settings in United States and other countries, largely with schizophrenia and schizoaffective disorders clients (Medalia et.al., 2000, 2003, 2019). In Singapore, cognitive remediation has been conducted in early psychosis intervention service with positive results (Chong et.al., 2021).

Meta-analyses of cognitive remediation has shown that while the rehearsal approach improves cognitive performance, the strategy learning approach has a greater effect size on functional outcomes (McGurk et.al., 2007; Wykes et.al., 2011). Deepening strategy learning in cognitive remediation is thus an important ingredient within cognitive remediation. In occupational therapy practice, the Multicontext Treatment Approach has been established as a credible and evidence-based framework on strategy learning (Toglia et.al, 2011, 2020). It utilises an over-arching metacognitive strategy approach that focuses on promoting self-awareness, self-monitoring skills, strategy generation and effective strategy use across a wide range of functional activities. The therapist works closely with the service user to determine single or multiple strategies that can be applied across a broad range of occupations, activities and tasks (Toglia, 2018). Thus, incorporating the Multicontext Treatment Approach as a strategy learning framework within NEAR will enhance skills acquisition for persons with cognitive impairment and may yield better functional outcomes.

In addition, literature over the past decade has highlighted the overlapping constructs between neurocognition, social cognition and negative symptoms in the pathway between symptomatology and functional outcomes (Hajdúk, et.al., 2021; Ventura et.al., 2009). Therefore, integrated neuro and social cognitive remediation have been developed, with some positive findings (DeMare et.al., 2019; Tan et.al., 2018) Such interventions, when contextualised to service users' occupational context, have been shown to improve social functioning and community independence (Mueller et.al., 2015. Furthermore, negative symptoms such as low motivation (ie: avolition) appears to play a significant mediating role in the outcomes of cognitive remediation (Lynch et.al., 2022). Therefore, strategies to enhance motivation, specifically the self-awareness and monitoring of motivation (ie: metamotivation) have also been considered as part of strategy learning.

In light of recent advancement in the research of cognitive remediation, this study attempts to integrate current knowledge in the various therapeutic ingredients of cognitive remediation to deliver an adapted NEAR intervention that meets the needs of community-dwelling persons with schizophrenia and schizoaffective disorders. The adapted NEAR intervention, which comprises of computer-based cognitive exercises and bridging groups, will be implemented in five community psychiatric rehabilitation centers, namely: 1) Anglican Care Center-Hougang; 2) Anglican Care Center-Simei; 3) Anglican Care Center-Bukit Batok; 4) Anglican Care Center-Yishun and 5) Anglican Care Center-Pasir Ris.

1. To investigate the effects of cognitive remediation on:

* neurocognition (measured by Brief Assessment of Cognition)
* social cognition (measured by Bell Lysaker Emotion Recognition Task)
* functional outcomes (Social and Occupational Functioning Assessment Scale and Canadian Occupational Performance Measure).
2. To investigate the mediators for change (eg: motivation and negative symptoms) in cognitive performance and functional outcomes.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

The intervention study model is a parallel randomized controlled trial. There will be two arms. The experimental arm is 'cognitive remediation' and the control arm is 'standard psychiatric rehabilitation'. Participants will be assigned to one of the treatment arms at the beginning of the trial and will continue in that arm throughout the length of the trial. Assignment to the group is done using a computer randomization generator. All eligible participants will be randomly assigned to one of the treatment arms (experimental or control arm) based on a 1:1 treatment allocation. Hence, those who are randomly allocated to the experimental arm will receive cognitive remediation throughout the trial, while those randomly allocated to the control arm will receive standard psychiatric rehabilitation throughout the trial. Both treatment arms will run in parallel.
Primary Study Purpose

Outcome Assessors
Upon randomization, the co-investigators will indicate the allocated group in a separate spreadsheet from the outcome measurements. The co-investigator who is collecting baseline, post-intervention and 8-week outcome measurements will be blinded to the treatment allocation of each participant.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Cognitive Remediation: Adapted Neuropsychological and Education Approach to Remediation (NEAR)

NEAR consists of using carefully selected computer cognitive games to restore cognitive functioning through rehearsal and strategy learning. It will be delivered 3 times a week for 12 weeks at the center. The duration of each session within the week is as follows: 1) First session: 45 min computer-assisted cognitive exercises + 30 min bridging group; 2) Second session: 30 min computer-assisted cognitive exercises + 45 min bridging group; 3) Third session: 45 min computer-assisted cognitive exercises. Computer-assisted cognitive exercises are sessions where participants engage in cognitive games that target different cognitive domains. In addition, the Multicontext Treatment Approach to strategy learning will be carried out. The metacognitive framework of self-evaluation and activity mediation will also be utilized. Bridging groups are conducted twice a week, to aid transfer of learning from the computer game sessions to the participants' everyday life.

Group Type EXPERIMENTAL

Cognitive Remediation: Adapted Neuropsychological and Education Approach to Remediation (NEAR)

Intervention Type BEHAVIORAL

NEAR consists of computer-assisted cognitive exercises to restore cognitive functioning through rehearsal and strategy learning. Based on the results of the baseline assessments, the therapist will complete the Cognitive Remediation Treatment Plan, to outline targeted cognitive domains and functional goals. During the cognitive games sessions, the Multicontext Treatment Approach will be used, where error patterns are identified. The participants will work on metacognition and use of strategies to overcome challenges faced during the computer games sessions. Bridging groups may include activities for participants to utilize strategies learnt during the computer game sessions to everyday living. Participants will also learn about cognitive impairments and how lifestyle modifications, mood regulation etc can affect cognitive performance. In addition, they will learn about metamotivation and build awareness about their motivation levels through self- reflection and self-monitoring.

Standard Psychiatric Rehabilitation at Anglican Care Centers

Participants in the control arm will attend their scheduled activities at their respective Anglican Care Centers. The Anglican Care Centers run a variety of activities to provide psychosocial rehabilitation for clients with serious mental illness. These may include vocational training such as training in a retail shop or café, instrumental activities of daily living training (eg: taking public transport, money management), psychoeducation, social skills training etc. Participants in the control arm will not be enrolled into the cognitive remediation.

Group Type OTHER

Standard Psychiatric Rehabilitation at Anglican Care Centers

Intervention Type BEHAVIORAL

Participants in the control arm will attend their usual psychiatric rehabilitation activities. These activities may include vocational training, community living skills training, psychoeducation, social skills training and peer support etc. These activities are also undertaken by participants in the experimental arm.
