Trial Outcomes & Findings for Effects of Treatment on Decision-making in Major Depression (NCT NCT01916824)

NCT ID: NCT01916824

Last Updated: 2017-11-21

Results Overview

Change in amount of money earned between baseline and after 6 weeks of antidepressant treatment is determined through a summary score from a variety of decision-making tasks. Participants received between $5 and $40 per visit, depending on the outcomes of the decisions made on the computerized tasks. Variable payment ensured that the decision-making tasks were approached realistically, as opposed to using hypothetical "points" that do not have meaning in the real world. Greater earnings indicate better financial decision-making. The specific tasks were: 1. risk task 2. balloon analogue risk task 3. temporal discounting task 4. ultimatum game 5. continuous performance task
