Bryce is a occupational therapist working with Sandy, a patient with brain injury. Bryce has decided to test the effects of a graphing strategy with Sandy. He starts the graphing technique while collecting data in the form of minutes of strength training per day. He discontinues the graphing technique and still collects minutes of strength training per day. Bryce then reintroduces the graphing technique. Bryce has employed which of the following types of single-subjects designs?
A) Case study Design
B) A-B Design
C) B-A-B Design
D) A-B-A Design

The B-A-B design involves collecting baseline data (A), implementing the intervention (B), removing the intervention to return to baseline (A), and then reintroducing the intervention (B) to see if the behavior changes again. In this case, Bryce starts with baseline data (no graphing technique), implements the intervention (graphing technique), returns to baseline (discontinuing the graphing technique), and then reintroduces the intervention (graphing technique) again to see if the behavior changes. Therefore, the best choice is B-A-B design.
