I highly recommend that you check out Greg Hanley's new website, www.practicalfunctionalassessment.com. If you're not familiar with him, he is a professor at Western New England University, and has written a lot about the functional assessment process over the years. I've been an admirer of his work for a long time, and the information on this site is perhaps the most substantive, yet practitioner-focused material on Functional Behavioral Assessments that you're likely to find. I just finished checking out one of the power points, and I am looking forward to going through the rest of the resources in more detail.
He and his team have developed a real unique way of conducting functional behavioral assessments. Here's a quick compare/contrast of the traditional functional analysis method and what he refers to as an Interview Informed Synthesized Contingency Analysis, or IISCA. I borrowed this slide right from one of the power points on practicalfunctionalassessment.com, which you can get here.
If you think others will benefit from this, pass on the address of Greg's site to your friends and colleagues, or feel free to use the share button below.
Lastly, I'm hoping to book Greg for the upcoming podcast, so stay tuned for future updates.
