Description of a practitioner training program on functional analysis and treatment development.

The current project examined the effectiveness of a functional analysis skills training package for practitioners with advanced degrees working within an applied setting. Skills included appropriately carrying out the functional analysis conditions as outlined by Iwata, Dorsey, Slifer, Bauman, and Richman (1982/1994), interpreting multielement functional analysis graphs using the methodology described by Hagopian et al. (1997), determining next steps when functional analysis data are undifferentiated, and selecting function-based interventions once functional analysis data are conclusive. The performance of three participants was examined within a multiple baseline design across participants. Although performance varied, baseline skill level was insufficient prior to intervention across participants and skill areas. Mastery was attained for all participants within four to eight training sessions per skill and the acquired skills were demonstrated effectively during generalization trials. Minimal retraining was required for some component skills at a 3-month follow up.
