Achieving socially significant reductions in problem behavior following the interview‐informed synthesized contingency analysis: A summary of 25 outpatient applications

Jessel et al. (2018) ran 25 back-to-back outpatient cases. Each child first got an interview-informed synthesized contingency analysis, or IISCA. Then the team built a functional communication training plan and slowly thinned the payoff schedule. Parents stayed in the room and gave acceptability ratings after each step.

Every single child hit at least a 90% drop in problem behavior. Caregivers also said the process felt doable and fair. The clinic kept seeing new kids, and the same pattern kept showing up—big, fast behavior gains.

Coffey et al. (2020) looked at 17 IISCA studies and reached the same upbeat view: the tool is quick and sets up treatment wins. Greer et al. (2020) disagree a bit; they found skipping the parent interview worked just as well, so the chat phase may not be needed. Fisher et al. (2016) ran stricter, single-contingency tests and saw the old-school FA beat IISCA four times out of five, but their lab setting used adult-directed provocation, while Jessel’s clinic let parents run gentle, brief sessions—an important difference. Retzlaff et al. (2020) warn that synthesized analyses can accidentally strengthen new problem behavior in lab cages; Jessel’s real-world safeguards—short trials, parent control, immediate FCT—seem to dodge that risk.

If you need a fast, parent-friendly FA that almost always leads to 90% behavior reduction, IISCA-driven FCT is hard to ignore. Start with the 30-minute open-ended interview, craft one synthesized test session, then roll straight into FCT plus thinning. Watch for over-generalization, but in outpatient care the recipe looks solid.
