Convergent validity has been used to evaluate the correlation between measurement tools. Delayed discounting has been used in order to determine the impulsivity in a variety of populations. Delayed discounting tasks have historically consisted of long, time consuming surveys. These tasks present participants with questions that relate to smaller sooner, or larger later rewards following various temporal delays. The purpose of the present study was to determine the convergent validity between a brief delayed discounting survey and a long, traditional version of the survey. The traditional survey consisted of 189 questions that contained 7 temporal delays and hypothetical money amounts. The brief survey was created based on the long survey but consisted of only 7 questions. Results from this study indicate that convergent validity did not exist between the two surveys. Keywords: delayed discounting, convergent validity, impulsivity
