A social validation assessment of the use of microswitches with persons with multiple disabilities

The purpose of this two-part study was to conduct a social validation assessment of microswitches versus interaction/stimulation conditions used with persons with multiple disabilities. In Part I, 32 teacher-assistant trainees were shown video-tapes reporting the use of microswitches versus interaction conditions for six children. In Part II, 40 teacher-assistant trainees or classroom aides and 44 rehabilitation staff were presented with video-tapes showing the use of microswitches versus systematic stimulation strategies for four adults. Raters scored the microswitch and the interaction or stimulation conditions on a 7-item questionnaire covering social/emotional and practical aspects. The microswitch condition was viewed as generally more positive than or comparable to the interaction or stimulation conditions. Main features of the findings and their implications are discussed.
