Effects of risperidone on aberrant behavior in persons with developmental disabilities: II. Social validity measures.

Author information

  • 1University of Kansas, Lawrence 66045, USA.


Consumer satisfaction and social validity were measured during a double-blind, placebo-controlled evaluation of the atypical neuroleptic risperidone in treating severe aberrant behavior of persons with developmental disabilities. First, a satisfaction survey was completed after a medication trial by each participant's caregiver. Results showed that 100% of the caregivers felt that participation was a positive experience for themselves and participants. Second, 52 community members viewed videotapes of 5 participants during a clinical interview when they were taking either placebo or risperidone. Raters also indicated that when on the medication, participants displayed fewer aberrant behaviors, were less irritable, in a better mood, and were more responsive to their environment.
