Real-Life Examples of ABAB Design Application in Therapy

📚 Quick Study Guide

🔍 ABAB design is a type of single-subject experimental design used to determine the effectiveness of an intervention. 📈 The design involves four phases: Baseline (A), Intervention (B), Baseline (A), and Intervention (B). 🧪 The first 'A' phase establishes a baseline of the target behavior before intervention. 🧩 The 'B' phase introduces the intervention and measures its effect on the target behavior. 🔄 The second 'A' phase removes the intervention to see if the behavior reverts to baseline. 💡 The second 'B' phase reintroduces the intervention to confirm its effect. 📊 The strength of the ABAB design lies in its ability to demonstrate a functional relationship between the intervention and the target behavior.

🧪 Practice Quiz

   2. The baseline phase.
   3. The follow-up phase.
   4. The control phase.
3. What happens during the 'B' phase of an ABAB design?
   1. The intervention is removed.
   2. Data collection is stopped.
   3. The intervention is introduced.
   4. A new baseline is established.
4. Why is the intervention removed in the second 'A' phase?
   1. To save time and resources.
   2. To see if the behavior reverts to baseline.
