Increasing Indices of Happiness and Positive Engagement in Persons With Profound Multiple Disabilities

摘要

This study assessed the effects of stimulation on indices of happiness and positive engagement in 4 persons with profound multiple disabilities. A strategy of systematic stimulus variation was used for presenting several stimuli. Data showed that indices of happiness were substantially increased in 2 participants and moderately or minimally increased in 2 others, whereas positive engagement was successfully increased in all 4 participants. Implications of the findings are discussed.
