The investigators will compare the test-retest reliabilities of two cognitive batteries in people with schizophrenia: Cognitive Drug Research Computerized Cognitive Assessment System ("CDR") and MATRICS Consensus Cognitive Battery ("MCCB"). The investigators hypothesize that there will be a statistically significant difference in the test-retest reliabilities between MCCB and CDR. In addition, the investigators hypothesize that each of the two batteries will better measure certain areas of cognition. The investigators also hypothesize that scores from both batteries will correlate with quality of life scores, and that there will be a significant difference between the correlations of MCCB and CDR. The investigators hypothesize there will be a significant difference in patients' self-reported tolerability and satisfaction of the MATRICS versus CDR assessments. Lastly, the investigators hypothesize that there will be a significant difference in the MATRICS versus CDR batteries with respect to an administrator-rated score of practicality.

Approximately 32 subjects will enroll in the study. Following consent and eligibility screening (visit 1) and baseline clinical assessment and training in the use of the CDR battery (visit 2), subjects will be randomized into one of two groups for visits 3 and 4. One group will complete the CDR and then MCCB in visit 3, as well as the Tolerability Scale for each battery. The other group will complete the batteries in reverse order during visit 3. Each group will complete both batteries again in reverse order for visit 4. Randomization will be done in blocks of 2. After completion of every 4 subjects, study administrators will complete the Practicality Scale for each battery.

Study Completion Date: March 2009
Primary Completion Date: March 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
MATRICS Consensus Cognitive Battery
Other: MATRICS Consensus Cognitive Battery
The MATRICS Consensus Cognitive Battery measures functioning across various cognitive domains, such as attention, working memory (verbal and nonverbal), learning (verbal and visual), reasoning and problem solving, and social cognition. Its measurements are based on timed paper-and-pencil, computerized, and orally-administered tests, as well as spatial tests using geometric cubes.
Other Names:
  • MCCB
Experimental: 2
Cognitive Drug Research Computerized Cognitive Assessment System
Other: CDR Computerized Cognitive Assessment System
Cognitive Drug Research Computerized Cognitive Assessment System consists of performance tasks that measure reaction time, numeric and spatial working memory, word and picture recall and recognition, and episodic secondary memory. CDR is a single, unified battery that can be stored and administered using a laptop computer.
Other Name: CDR

Inclusion Criteria:

  1. Women and men aged 18-65 with DSM-IV diagnosis of schizophrenia or schizoaffective disorder (depressed type) by diagnostic interview and chart review.
  2. Clinically stable on a stable dose of antipsychotic medication for at least one month; no current active suicidal ideation.
