I would recommend them to review evidence based interventions, using this article as an example. This article demonstrates that even with a very basic intervention of putting on florescent light covers or not having the light covers, there could be evidence to show how problem behaviors (stereotypy) and on-task behaviors are influenced by the independent variable of light cover or no light cover. In this study’s case, it was fairly apparent that there were increasing trend in stereotypy whenever the light cover is on and a decreasing trend or low level of stereotypy whenever the light cover is off. Also, there is an increasing trend in on-task behavior whenever the light cover is off and a decreasing trend in on-task behavior whenever the light cover is on. This is very interesting and demonstrates to all service providers and caregivers that a simple experiment can help us recognize what interventions actually work or do not work.
