Abstract

A variety of variables have been found to augment perceived social validity of behavioral interventions. In the present study, potential effects of behavioral function were evaluated. Sixty students inexperienced in work with people with mental retardation, and 60 experienced staff watched one of two carefully matched acted videos depicting self-injury maintained by attention or escape from task demands. Participants were also told whether the self-injury depicted typically led to mild or severe consequences for the person filmed. Participants rated six interventions in terms of their acceptability and effectiveness for the behavior depicted. A hierarchy of acceptability was replicated: reinforcement-based procedures were rated as more acceptable and effective. There were also effects of behavior severity and rater experience. However, few effects of behavioral function were found. Potential implications of staff undifferentiated attitudes towards functional treatments are discussed.
