The document discusses strategies for problem solving when a functional analysis (FA) yields undifferentiated results about the function of problem behavior. It recommends conducting a within-session analysis to identify patterns in behavior, extending the alone/ignore condition to assess automatic reinforcement, and using a reversal or pairwise FA design to control for confounds. Evidence of successful problem solving includes seeing differentiated results or temporal patterns, while continuing undifferentiated data or decreasing behavior in the alone condition provides evidence problem solving was not successful.
