Abstract

Temporal discounting can be used to evaluate impulsivity in various populations. One assessment measure that can be used is a monetary choice questionnaire in which individuals are provided with an option to select a specified amount of money now, or a different amount following a temporal delay. This study examines the convergent validity of a long monetary choice questionnaire consisting of 189 questions and a brief monetary choice questionnaire consisting of 7 questions, in which participants can select all of the amounts they would prefer to acquire. The results of this study suggested that there is convergent validity between the two surveys through the use of Pearson’s correlation (r=.648, p< .001) and a paired samples t- test that demonstrated that the difference between the AUC scores was not significant (p=.287). Keywords: discounting, convergent validity, impulsivity, self- control, temporal discounting
