About this study
Background: People with psychosis show profound deficits in memory. A new cognitive remediation therapy using an app on a computer or mobile phone to improve memory has been effective in this population, but the neurobiological effects are unknown.
Objectives: 1) To use functional magnetic resonance imaging (fMRI) to examine brain changes during a working memory task before and after a 12 hour memory training intervention on a computer or mobile phone, 2) To use diffusion tensor imaging (DTI) to examine white matter connecting prefrontal and parietal lobe before and after training.
Methods: 46 people with psychosis will be randomized to a computerized training of either memory training or a control condition of non-memory games (language/card games) and will self-administer 4 hours of training over 4 days per week, for 3 weeks (12 hours total). Memory training will be done with the Peak app http://www.peak.net. Imaging data will be gathered with a 3 Tesla scanner pre and post training.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Peak app for memory trainingBehavioural
Non-memory training groupBehavioural
| Study group | Role | What they receive |
|---|---|---|
| Memory training group | Experimental | The intervention is self-administration of 4 hours of memory training over 4 days per week, for 3 weeks (12 hours total). Memory training will be done with the Peak app for memory training http://www.peak.net. Receives: Behavioral: Peak app for memory training |
| Non-memory training group | Active comparator | The intervention is self-administration of 4 hours of training of games that do not involve memory such as language and card games over 4 days per week, for 3 weeks (12 hours total). Receives: Behavioral: Non-memory training group |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in functional Magnetic Resonance Imaging blood oxygen-dependent signal during working memory task performance before and after a 12 hour memory training intervention in people with early psychosis
Measured: 5 weeks
Change in diffusion tensor imaging measured change in fractional anisotropy during working memory task performance before and after a 12 hour memory training intervention in people with early psychosis
Measured: 5 weeks

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 Magnetic Resonance Imaging blood oxygen-dependent signal during working memory task performance before and after a 12 hour memory training intervention in people with early psychosis (time frame: 5 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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?
