In 2008, the "Journal of Positive Behavior Interventions" ("JPBI") celebrated 10 years in publication. As the flagship journal of positive behavior support (PBS), it is important to periodically examine the research published in "JPBI" to determine whether it reflects the basic principles of PBS, to explore the ways in which PBS is being practiced, and to consider future directions for PBS. We analyzed various dimensions of intervention research studies published in "JPBI" during the first 10 years. The data indicate that research has increasingly become aligned with PBS principles in many areas, yet other areas merit additional focus in the future. (Contains 1 figure and 3 tables.)
