The current trend analysis was conducted to empirically document the characteristics of individuals with autism who participated in intervention research published between 1995 and 2009 in three journals (Journal of Applied Behavior Analysis, Journal of Autism and Developmental Disorders, and Focus on Autism and Other Developmental Disabilities). Information was collected on age of participants, cognitive and communicative functioning, setting, and ecological variables. Overall, the data are interpreted to document few changes over time; however, increasing trends were noted in the proportion of studies that included children below the age of 6 years and in the proportion of studies that included higher functioning participants. The data are discussed in relation to the status of intervention research and demographic changes pertaining to autism.
