Functional analysis (FA) is a tool practitioners can utilize to identify the function of challenging behavior. An interview informed contingency analysis (IISCA) is a variation of a FA. In an effort to improve patient care within a university-based clinic, a within-session analysis of the first test condition of an IISCA was conducted to determine if a shorter assessment yield results similar to the full IISCA. An alternating treatments design was used to evaluate differentiated rates of challenging behavior across conditions for eleven client cases at the university-based clinic. A single test session was enough to determine the function of challenging behavior and the first test condition produced similar results to the whole IISCA for some of the cases reviewed.
