Does Awareness of either Psychotropic Medication or Behavioral Interventions Bias College Students' Ratings of a Child's Behavior?

Caregiver awareness that a child receives either psychotropic medication or behavioral intervention could bias that caregiver's perception of the child's behavior and give rise to incorrect conclusions about intervention effectiveness. To evaluate bias for the effects of either medication or behavioral intervention, we randomly assigned 114 participants to one of the four groups: Medication information (Med info), Behavioral information (Beh info), No change (control group), and Reverse video (Rev Vid; also no change, but participants watched videos in the reverse order). Participants watched two 5-min video clips of a child engaging in low to moderate levels of problem behavior. After watching the first video, participants rated the child's problem behavior. Before viewing the second video, participants were informed that (a) the child received medication (Med info group), (b) the child received behavioral intervention (Beh info group), or (c) no treatment changes were made (No change groups). Results show that providing treatment information did not bias participants' ratings of the child's behavior. Instead, results indicate participants in the control groups correctly tracked actual changes in the child's behavior.
