Background and study aims
Psychosis is a mental health problem that causes people to perceive or interpret things differently from those around them, and might involve hallucinations or delusions. Schizophrenia is a type of psychosis. Functional and recovery outcomes are poor in patients with schizophrenia in terms of work, their self-care and their relationships. Cognitive remediation therapy (CRT) is a type of rehabilitation treatment that aims to improve abilities such as attention and memory. Most findings on CRT challenge the assumption that simply improving cognitive functioning in schizophrenia will spontaneously lead to better outcomes. The aim of this study is to find out whether targeted CRT (ReMind) is better than conventional CRT at improving functional outcomes in first-episode psychosis patients.
Who can participate?
First-episode psychosis patients aged 18 to 40
What does the study involve?
During the first visit, participants answer a set of questionnaires and attempt a cognitive test. Participants are randomly allocated to targeted CRT (ReMind) or conventional CRT for 15 sessions over 8 weeks. The questionnaires are repeated after the treatment sessions to measure the difference in cognitive functioning. Participation in this study takes about two months with three months follow-up.
What are the possible benefits of participating?
Participants gain knowledge about cognition and schizophrenia, recovery and cognitive skills. There are no known risks and/or discomforts associated with the treatment in this study.
Where is the study run from?
Hospital Putrajaya, Hospital Kajang, Hospital Kuala Lumpur and UKM Medical Centre (Malaysia)
When is the study starting and how long is it expected to run for?
February 2016 to October 2019

| Scientific title | The efficacy of cognitive remediation on processing speed in patients with first episode psychosis: a randomized controlled trial |
| Study acronym | ReMind |
| Study objectives | Current hypothesis as of 09/12/2020: To evaluate whether the targeted CRT (ReMind) is superior to conventional CRT in improving global cognitive functioning in first-episode psychosis (FEP) patients. _____ Previous hypothesis: To evaluate whether the adjunct CRT (A-NEAR) is superior to conventional CRT in improving global cognitive functioning in first episode psychosis (FEP) patients. |

| Intervention | This single-blinded randomised controlled trial will address the efficacy of CR therapy using NEAR model by targeting processing speed in first episode psychosis. Participants’ cognition, functioning and clinical symptoms will be assessed at baseline and then randomised to treatment arm (adjunct CRT (A-NEAR)) or standard care of conventional CRT as active control for 15 sessions over 8 weeks. All participants will be assessed again at post-randomisation assessment with 3 months follow-up. A sequential mixed methods design will be used, in which the intervention will be executed in sequence followed by in-depth interview before the data could be embedded. There will be a primary outcome of improvement in global cognition and psychosocial functioning as a secondary outcome. All procedures and reporting of primary and secondary outcomes will follow Consolidated Standards of Reporting Trials (CONSORT) 2010 guidelines. The primary purpose of ReMind study will be to execute intervention of CR with the use of quantitative instruments to test the eclectic theories of neuropsychological, learning, educational psychology and rehabilitation psychology that predict the treatment effect between independent variables of A-NEAR treatment that will influence positively the performance of cognitive domains and functional outcomes as dependent variables in patients with first episode psychosis with processing speed as mediator. Randomisation and allocation concealment Signed informed consent will be obtained prior to randomisation. The single blinded (masked) assessors will recruit the participants through demographic data and assessments. After a comprehensive baseline assessment, those meeting the eligibility will be randomized. Thereafter, a randomisation is performed, the potential participants will be informed of the result of the randomisation. The patients and treatment providers will not be blinded. The blinding applies to ReMind training team involved in assessments, data management, data analysis, and drawing outcome conclusions. Successful randomisation in practice depends on two interrelated aspects which adequate generation of an unpredictable allocation sequence and concealment of that sequence until assignment occurs. The treatment allocation system will be set up so that the person enrolling participants does not know in advance which treatment the next person will get, a process termed allocation concealment. Although there are many approaches to randomization that are known to effectively conceal the randomization sequence, the use of sequentially numbered, opaque sealed envelopes (SNOSE) will be adopted in the study as it is the most accessible and straightforward method of maintaining allocation concealment and does not require the use of specialized technology. Moreover, the method is both cheap and effective in ensuring source of bias can be eliminated by concealing the upcoming allocation sequence from researchers and participants. For primary and secondary outcomes, the assessments will be conducted at baseline, prior to randomisation, as information from the baseline assessment is used to perform randomisation and validate inclusion and exclusion criteria. The post assessment will also be administered after 8 weeks of intervention. |
