What the study is about

The goal of this study is to determine the effects of stimulant medication on disruptive behavior, function, preference and choice; however, it is primarily methodological and will add to current research by establishing an effective evaluation of the impact of stimulant medication on these behaviors. Three behavior assessments for children and adolescents diagnosed with AD/HD who exhibit disruptive behavior will be conducted:

  • Preference assessments will be conducted to determine whether preference for social and nonsocial items and activities differs under medication and non-medication conditions.
  • Functional analyses will be conducted to determine whether stimulant medication has an effect on the frequency and function or purpose of disruptive behavior.
  • Choice assessments will be conducted to evaluate the impact of stimulant medication on impulse control/delay discounting.

This study will be conducted in three phases. For each of the 5 to 10 participants there will be 8 total visits. The first 4 visits will entail a preference assessment, followed by a functional analysis. On visits 1 and 3, the participant will be asked to take his/her stimulant medication as is typically done; however, on visits 2 and 4, the participant will be asked to refrain from taking the medication.

For visits 5-8, participants will continue to participate in preference assessments, but will also be presented with a choice arrangement with work and play. In the choice arrangement, participants will be given four work cards and four play cards that they can organize in any order. Work cards will be associated with a brief academic task and play cards will be associated with a brief play period using high-preferred toys/activities. On visits 5 and 7 the participant will be asked to take his or her stimulant medication as usual, while on visits 6 and 8 the participant will be asked to refrain from taking his or her medication.
