MonetaryChoice Questionnaire (MCQ) Description of Protocol
The MonetaryChoice Questionnaire (MCQ) is a 27item, selfadministered questionnaire. For each item, the participant chooses between a smaller, immediate monetary reward and a larger, delayed monetary reward. The protocol is scored by calculating where the respondent’s answers place him or her amid reference discounting curves, with placement amid steeper curves indicates higher levels of impulsivity. For more information about the MCQ, please refer to www.cognitiveatlas.org/task/id/tsk_4a57abb949e98 Cognitive Atlas Interpretation. Specific Instructions
There is considerable evidence that the use of hypothetical and the use of real awards in delayed discounting produce very similar results (Lawyer et al., 2011). The estimate of the subject’s discounting constant “k” provided by the MonetaryChoice Questionnaire (MCQ) generally has correlated well with that obtained by a more comprehensive set of computerized intertemporal reward choices (Epstein et al., 2003). However, this set of questions has been shown to result in a “ceiling effect” of severe discounting that fails to distinguish between very impulsive individuals, such that additional questions may need to be added to discriminate them (Towe et al., 2015). Protocol
MonetaryChoice Questionnaire For each of the next 27 choices, please indicate which reward you would prefer: the smaller reward today, or the larger reward in the specified number of days. 1. Would you prefer $54 today, or $55 in 117 days? [ ] smaller reward today [ ] larger reward in the specified number of days 2. Would you prefer $55 today, or $75 in 61 days?

[ ] smaller reward today [ ] larger reward in the specified number of days 21. Would you prefer $34 today, or $50 in 30 days? [ ] smaller reward today [ ] larger reward in the specified number of days 22. Would you prefer $25 today, or $30 in 80 days? [ ] smaller reward today [ ] larger reward in the specified number of days 23. Would you prefer $41 today, or $75 in 20 days? [ ] smaller reward today [ ] larger reward in the specified number of days 24. Would you prefer $54 today, or $60 in 111 days? [ ] smaller reward today [ ] larger reward in the specified number of days 25. Would you prefer $54 today, or $80 in 30 days? [ ] smaller reward today [ ] larger reward in the specified number of days 26. Would you prefer $22 today, or $25 in 136 days? [ ] smaller reward today [ ] larger reward in the specified number of days 27. Would you prefer $20 today, or $55 in 7 days? [ ] smaller reward today [ ] larger reward in the specified number of days Scoring A participant’s discounting curve may be calculated according to the following function: V = A/(1+kD) V is the present value of the delayed reward A at delay D, and k is the rate of discounting; k typically falls between 0.0 and 0.5, with smaller values indicating a lack of discounting and preference for delayed rewards and higher values indicating strong discounting and a preference for immediate rewards. Thus higher values of k are indicative of high levels of impulsivity. There are two ways of scoring the MonetaryChoice Questionnaire. The first involves hand scoring to get an estimate of k following the guidelines given in Kirby (2000). The second involves fitting a logistic regression function to individual responses following procedures described in Wileyto et al. (2004). Estimating Discounting Rate The following table lists the calculated k values (the degree of discounting) at indifference for each question (i.e., when the subjective value of the immediate and delayed rewards are equivalent).
An estimate of the respondent’s discounting rate can be calculated as the geometric mean (to avoid underweighting) of the k at indifference between the two questions that reflect when the respondent changes between choosing the delayed reward versus the immediate reward. In cases where the respondent’s change between preferring the delayed versus the immediate reward is not consistent, the two questions that are most proportional to their responses are chosen. If the participant always chooses the immediate reward or the delayed reward, the estimation of k is equal to one of the endpoints (0.25 or 0.00016). Variables
Selection Rationale
Delayed Reward Discounting has been shown to be moderately associated (d ~ .4.6) with a broad range of addictive behaviors and can predict initiation of substance use (MacKillop et al., 2011; AudrainMcGovern et al., 2009). The Monetary Choice Questionnaire has been shown to be temporally stable, has been used with adolescents, and is highly correlated (r = 0.82) with computerbased experimental methods. Source
