The author found it very satisfying to reread "Toward a technology of 'nonaversive' behavioral support," written in 1990 by Rob Horner and seven of his colleagues. Their predictions of the critical themes for advancing positive behavior support (PBS) ring true. Fifteen years have passed since the publication of this article, and much has happened in the interval. There were press conferences and television interviews on the use of punishment and SIBIS (Self-Injurious Behavior Inhibiting System) to reduce problem behavior. Inside and outside of Washington, DC political struggles took place over infusing PBS language into educational law. Soon the rhetoric became louder than the research. TASH forged ahead with solid resolutions and the Arc, AAMR, and other organizations joined the battle for PBS. This commentary revisits themes of positive programming set forth by Horner et al. (1990), asks how the field has advanced, and identifies ongoing challenges. Rather than use the original order of the presentation of themes in their article, the author has grouped them into two categories: themes that have seen significant change and those reflecting little change.
