Detailed Description

Schizophrenia is a chronic brain disorder that causes severe disability. It is characterized by psychotic symptoms, including hallucinations and delusions. Neurocognitive deficits, such as impaired neurocognitive processing efficiency, also affect people with schizophrenia. This deficiency in the speed and accuracy with which the brain perceives and responds to targets causes scrambled messages to be transmitted in the brain, thereby affecting executive control and memory. Medications are available that effectively treat the psychotic symptoms. The neurocognitive deficits, however, do not subside with medication treatment, and are responsible for the failure to improve the e their psychosocial functioning of people with schizophrenia, even after their psychotic symptoms have gone into remission. The targeted cognitive training (TCT) exercises in this study are specifically designed to improve speed and accuracy in the perception of and response to verbal and visuo-spatial targets. This study will determine the effectiveness of reward-intensive, computer-based TCT in improving neurocognitive deficits in people with schizophrenia.

Participants in this double-blind study will be paired according to IQ and baseline symptom severity. One member of each pair will be randomly assigned to training exercises that use TCT. The other will be assigned to a control intervention, which will involve commercially available computer games. All participants will complete exercises with their assigned intervention for 1 hour per day, 5 days per week, until 90 hours of training has been accumulated. Neuroimaging will be performed on a subgroup of participants to examine changes in brain activation patterns in response to the cognitive training. Upon study completion and at the 6-month follow up visit, participants will be assessed for improvement in the following areas: cognitive performance; symptom profile; quality of life; and social cue recognition.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: 1
Participants will use commercially available computer games
Behavioral: Computer games
The control treatment involves commercially available computer games that participants practice 1 hour per day, 5 days per week, for 20 weeks.
Experimental: 2
Participants will receive targeted cognitive training with neuroplasticity-based software created by Posit Science Corporation
Behavioral: Targeted cognitive training (TCT)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Cognitive performance as measured by a neuropsychological battery
Time Frame: Measured at Weeks 8, 14, and 8 and Month 6 follow-up
Measured at Weeks 8, 14, and 8 and Month 6 follow-up

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Symptom profile as measured by clinical interviews
Time Frame: Measured at Weeks 8, 14, and 8 and Month 6 follow-up
