Trial Outcomes & Findings for Executive Dysfunction and Suicide in Psychiatric Outpatients and Inpatients (NCT NCT01043432)

NCT ID: NCT01043432

Last Updated: 2015-05-12

Results Overview

Iowa Gambling Test - Total Raw Score The Iowa Gambling task requires examinees to sit in front of a computer screen displaying four decks of cards (Decks A, B, C, and D) and select a card from any of the four decks. Decks A and B are the disadvantageous decks because they produce high immediate gains however over time examinees will experience a higher loss. Decks C and D are the advantageous decks because they produce lower gains but over time examinees will experience smaller losses. Examinees will make 100 choices (trials). To measure performance, the 100 trials are divided, in order, into 5 'blocks' of 20. A net score is calculated for each block as the number of cards selected from the advantageous decks minus the disadvantageous decks and the total raw score is the sum of the scores for blocks 1-5. The overall total score can range from -100 (worst outcome) to 100 (best outcome)and the score for each block can range from -20 to 20
