Functional analyses (FAs) are used to identify the maintaining contingencies of problem behavior. However, FAs present some limitations. Functional analyses can be time consuming. In this study we evaluated the efficiency and correspondence of a modified trial-based FA versus a session-based FA, in a controlled setting. We conducted both the trial-based and session-based FAs with five subjects that engaged in problem behavior. On average, the trial-based FAs were completed in 32.8% less time than the session-based FAs, and took 40% less meeting and calendar days than the session-based FAs. Based on the analyses of four Board Certified Behavior Analysts (Doctoral), we obtained an 85% overall correspondence, and 95% individual function correspondence. The trial-based FA reduced assessment duration and increased correspondence to the session-based FA as compared to previous research. Therefore, these results suggest this modification to the trial-based FA may be a viable alternative to the session-based FA.
