Description:
The Monetary-Choice Questionnaire (MCQ) is a 27-item, self-administered 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.

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 Monetary-Choice 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).
Question | k at indifference |
13 | .00016 |
1 | .00016 |
9 | .00016 |
20 | .00040 |
6 | .00040 |
17 | .00040 |
26 | .0010 |
24 | .0010 |
12 | .0010 |
22 | .0025 |
16 | .0025 |
15 | .0025 |
3 | .0060 |
10 | .0060 |
2 | .0060 |
18 | .016 |
21 | .016 |
25 | .016 |
5 | .041 |
14 | .041 |
23 | .041 |
7 | .10 |
8 | .10 |
19 | .10 |
11 | .25 |
27 | .25 |
4 | .25 |
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).

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 Monetary-Choice 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).

Definition
This measure assesses whether the participant prefers smaller immediate rewards over delayed larger rewards.
Purpose
This measure captures devaluation of rewards as a function of delay. This is a decision-making dimension of impulsivity and may predict initiation of substance use and is characteristic of childhood externalizing disorders. When compared with the general population, adolescents with conduct disorder, drug users, and drug abusers show greater preference for small but immediate rewards and more readily discount a larger but long-term reward. Thus, substance users may prefer the immediate euphoria of substance use over the longer-term benefits of abstinence (i.e., maintaining employment, relationships, and physical health) (Kirby et al., 1999).
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; Audrain-McGovern 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 computer-based experimental methods.
