About this study
Cognitive remediation (CR) is the best treatment to improve neurocognitive abilities for individuals with psychosis, however, there is no gold standard method of cognitive remediation available. Cognitive training refers to the training component of CR in which people practice computerized exercises that train specific cognitive abilities. There is no agreed upon approach within the field as to the type of training that is most effective with some studies, training higher level cognitive abilities, some training perceptual abilities, and others training general cognitive skills. This study will directly compare two competing methods of cognitive training on measures of neurophysiology, neurocognition, functional competence, and real-world functional performance.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Cognitive Remediation - Executive TrainingBehavioural
Cognitive remediation is a cognitive and behavioural therapy designed to improve cognitive skills such as memory, and problem solving ability.
Cognitive Remediation - Perceptual TrainingBehavioural
Cognitive remediation is a cognitive and behavioural therapy designed to improve cognitive skills such as attention, and processing speed.
| Study group | Role | What they receive |
|---|---|---|
| Executive Training | Experimental | Executive Training (ET) involves training on computerized cognitive exercises that have graded increases in difficulty so that the participant is always challenged. A therapist will be in the room with participants to address any difficulties with the program and facilitate generation of strategies. ET will be delivered in both individual and group settings. Receives: Behavioral: Cognitive Remediation - Executive Training |
| Perceptual Training | Experimental | Perceptual Training (PT) involves training on computerized cognitive exercises that have graded increases in difficulty so that the participant is always challenged. A therapist will be in the room with participants to address any difficulties with the program and facilitate generation of strategies. PT will be delivered in both individual and group settings. Receives: Behavioral: Cognitive Remediation - Perceptual Training |

Questions about this trial
What is this clinical trial studying?
A study testing Cognitive Remediation - Executive Training and Cognitive Remediation - Perceptual Training in people with Psychotic Disorders, run by Queen's University at 1 site in Canada.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 14 Nov 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Functional Performance - Specific Levels of Functioning (SLOF) from Baseline (time frame: Post-treatment (within 2 weeks following the end of treatment)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03024203, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Nov 2018; AzTrials last refreshed its copy on 7 Nov 2026.
