Masking: Open Label
Primary Purpose: Treatment
Official Title: Pilot Study of Performance-based Reinforcement to Enhance Cognitive Remediation Therapy for Substance Users

Further study details as provided by Yale University:

Primary Outcome Measures:
  • Improvement in performance scores on computerized cognitive remediation tasks [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]
    Performance scores on various computerized cognitive remediation tasks will be measured repeatedly during the 4 week study. These scores include "time to completion", "number of errors", "number of words correctly recalled", and "percentage of task completed"

Secondary Outcome Measures:
  • Improved cognitive function on neuropsychological tests [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]
    Change in cognitive function between baseline and post-treatment will be measured by performance on neuropsychological tests, such as Trail Making Test A & B, Wisconsin Card Sort Test, Digit Symbol Test from WAIS-IV, and the Continuous Performance Test-II (CPT-II).

Detailed Description:

Forty individuals seeking treatment for an alcohol or cocaine use disorder at the Substance Abuse Treatment Unit (SATU) will be randomized to receive cognitive remediation therapy with or without additional compensation based on performance. Participants will use the computerized cognitive remediation program (PSSCogRehab 2012) three times per week for four weeks. The primary outcome measure will be an improved performance on the computerized tasks, with secondary outcomes of changes in cognitive functioning (e.g., attention, concentration, memory) as measured by neuropsychological tests between baseline and post-treatment.
