  Purpose
This research is being done to learn if computer tasks that challenge the brain (cognitively stimulating tasks) can improve memory and other types of thinking. The study will compare the effects of different versions of the computer tasks. It also will compare the task performance of different groups of people.

Condition Intervention Phase
Substance Use Disorders
Behavioral: Computerized cognitively stimulating activities
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Effects of Cognitive Training in Methadone Maintenance Patients

Further study details as provided by Johns Hopkins University:

Primary Outcome Measures:
  • Working Memory [ Time Frame: baseline, 7 weeks ]
    Change in maximum number of digits correctly recalled in Digit Span Backwards task, from baseline to 7 weeks


Secondary Outcome Measures:
  • Episodic Memory [ Time Frame: baseline, 7 weeks ]
  • Trail-making [ Time Frame: baseline, 7 weeks ]

  • Addiction Severity Index [ Time Frame: baseline, 7 weeks ]
  • Delay Discounting [ Time Frame: baseline, 7 weeks ]
  • Digit Symbol Substitution Test [ Time Frame: baseline, 7 weeks ]

Enrollment: 134
Study Start Date: December 2010
Study Completion Date: July 2013
Primary Completion Date: July 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Adaptive cognitively stimulating activities Behavioral: Computerized cognitively stimulating activities
