Brief Summary:
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.

Arms and Interventions
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Experimental: Executive Training
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.
 Behavioral: Cognitive Remediation - Executive Training
Cognitive remediation is a cognitive and behavioural therapy designed to improve cognitive skills such as memory, and problem solving ability.
Experimental: Perceptual Training
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.
 Behavioral: Cognitive Remediation - Perceptual Training
Cognitive remediation is a cognitive and behavioural therapy designed to improve cognitive skills such as attention, and processing speed.


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Change in Functional Performance - Specific Levels of Functioning (SLOF) from Baseline [ Time Frame: Post-treatment (within 2 weeks following the end of treatment) ]
    Rating scale completed by participants' case managers that rates their ability to perform different everyday tasks


Secondary Outcome Measures :
  1. Change in Neurocognition - MATRICS Cognitive Consensus Battery (MCCB) from Baseline [ Time Frame: Post-treatment (within 2 weeks following the end of treatment) ]
    The MCCB is the gold standard cognitive assessment for schizophrenia research

  2. Change in Neurophysiology - EEG from Baseline [ Time Frame: Post-treatment (within 2 weeks following the end of treatment) ]
    Alpha and Theta band synchronization, p300, mismatch negativity

  3. Functional Competence - Canadian Objective Assessment of Life Skills Brief (COALS-B) from Baseline [ Time Frame: Post-treatment (within 2 weeks following the end of treatment) ]
    Performance based measure of real life functional skills using role-play

  4. Change in Functional Performance - Specific Levels of Functioning (SLOF) from Baseline [ Time Frame: Follow-Up (3 months after the end of treatment) ]
    Rating scale completed by participants' case managers that rates their ability to perform different everyday tasks

  5. Change in Neurocognition - MATRICS Cognitive Consensus Battery (MCCB) from Baseline [ Time Frame: Follow-Up (3 months after the end of treatment) ]
    The MCCB is the gold standard cognitive assessment for schizophrenia research

  6. Change in Neurophysiology - EEG from Baseline [ Time Frame: Follow-Up (3 months after the end of treatment) ]
    Alpha and Theta band synchronization, p300, mismatch negativity

  7. Functional Competence - Canadian Objective Assessment of Life Skills Brief (COALS-B) from Baseline [ Time Frame: Follow-Up (3 months after the end of treatment) ]
    Performance based measure of real life functional skills using role-play
