For conducting a survey in my research project, I am now evaluating 2 questionnaires that are both based on behavioral economic theories of addiction. Yet they are different in the structure, measurements and likelihood of responses. The first, Pleasant Events Schedule (PES), allows to measure the potency of reinforcement of activities and compare the level of reinforcement between alcohol-related and alcohol free activities, although it consists of 300+ items and has not been reevaluated. The second, Survey of Rewards for Teens (SORT), gives a list of 55 items which represent rewards and requires the participants only to give a preference on the items.
The question is addressed especially to experts of behavioural psychology and/or behaviour economics.
Can I measure the potency of reinforcement also in a list of rewards such as in SORT?
