Question

Quizplus · Accepted Answer

Multiple-baseline design is appropriate for evaluating the effectiveness of a program for treating stuttering because it involves introducing the treatment at different points in time for different behaviors, settings, or individuals. This design allows the therapist to see if the treatment has a true effect by comparing baseline data to treatment data across multiple baselines. It controls for extraneous variables and establishes causal relationships between the treatment and outcome. Other designs such as ABAB, alternating-treatments, or changing criterion may not be as appropriate for evaluating a program for treating stuttering because they do not allow for comparison of different baselines, behaviors, settings, or individuals, and may not control for extraneous variables as well.
