Description:

Purpose		ToAD is designed to measure individual time discount rates using an adaptive algorithm. The monetary amount, time delay, and signs (gain domain & loss domain) can be easily configured. Also, the procedure can detect the zero discounting and the negative discounting.
Questions		10 questions. The procedure is integrated with Qualtrics survey.
Sub-scales
Domain		Personality Constructs: Impulsiveness
Sample items		Gain domain example (Amounts and delays will be dynamically generated based on a researcher's configurations). 1. Which payoff option would you prefer? Getting $120.12 today Getting $471.42 in 190 days Getting $603.35 in 288 days Loss domain example. (Amounts and delays will be dynamically generated based on a researcher's configurations) 1. Which payment option would you prefer? Paying $111.79 today Paying $233.51 in 120 days Paying $641.84 in 408 days Qualtrics demo is available at https://decisiontimes.org/toad/
