Primary Purpose: Treatment
|Official Title:||Efficacy of a Cognitive Remediation Treatment Program for Bipolar Disorder|
- MATRICS MCCB Battery [ Time Frame: Post-treatment; after 6 months no active intervention ] [ Designated as safety issue: No ]
The MATRICS battery includes 10 tasks that measure processing speed, attention, working memory, verbal learning, visual learning, problem solving and social cognition. Total administration time is 60-90 minutes.
The second assessment point will measure change after the initial outcome (that is, change from post-treatment after 6 months of no active intervention).
- Young Mania Rating Scale [ Time Frame: Pre-treatment; Post-treatment; after 6 months of no active study intervention ] [ Designated as safety issue: No ]Brief questionnaire asking about manic symptoms; duration = approximately 10 minutes
- Montgomery-Asberg Depression Rating Scale [ Time Frame: pre-treatment; post-treatment; after 6 months of no active study intervention ] [ Designated as safety issue: No ]Brief questionnaire administered by study staff regarding level of depressive symptoms; duration = approximately 10 minutes
- Positive and Negative Syndrome Scale [ Time Frame: pre-treatment; post-treatment; after 6 months of no active study intervention ] [ Designated as safety issue: No ]Interview-administered questionnaire asking about positive and negative symptoms of psychosis, and general psychiatric symptoms; duration = approximately 20 minutes
- Multnomah Community Ability Scale [ Time Frame: pre and post treatment; after 6 months of no active study intervention ] [ Designated as safety issue: No ]The MCAS measures functioning in psychiatric patients in multiple domains (e.g. social interest/effectiveness, independence, and meaningful activities). Administered in interview format; duration = approximately 10 minutes
- Social and Occupational Functioning Assessment Scale [ Time Frame: pre and post treatment; after 6 months of no active study intervention ] [ Designated as safety issue: No ]The SOFAS is a 100-point scale similar to the Global Assessment of Functioning designed to evaluate social and occupational functioning not directly influenced by psychological symptom severity.

Experimental: Cognitive Remediation
This arm will receive computer-based cognitive remediation treatment 3 times per week for 24 weeks, for a total of 70 hours of treatment
13 programs targeting cognition in 4 separate domains: Auditory processing, visual processing, social cognition, and executive functioning. Games are imbedded in a format that is engaging and interactive. Animated characters serve as "directors" for each program, explaining the tasks in both verbal and written formats and providing feedback on each trial and overall after each activity. Users move systematically through the programs and can track their progress as the go. Each session includes activities from several different games to maintain interest and train a variety of skills; however, games are presented in the order of domains listed above (i.e. auditory, then visual, then social, and finally executive) to avoid stimulus interference during the training.
Placebo Comparator: Computer Control
Group will receive 70 hours of computer time playing pre-selected computer games administered in a similar format as the Cognitive Remediation condition
Behavioral: Computer Control
Sessions will involve generic computer games administered via the game interface "Sporcle." Sporcle is a game site that offers a collection of quiz-type activities available on line. The activities include typing, basic timed arithmetic (e.g. simple addition); picture identification (e.g. name the corporate logo; name the sitcom), and subject-based quizzes in areas like history (e.g. name the US presidents), geography (e.g. name the state capitals), and literature (e.g. book title fill-in-the-blank). An administrator can track the activity of subjects including when they logged in, which games they played and for how long, and what their accuracy was on each game. We will use a pre-developed game schedule that includes a mix of each type of game in each session, and ensures that subjects are playing the same games in the same order. This format was developed to mirror the treatment condition, as subjects are given a variety of specific games to play at each session.
