Another way to introduce experimental control is by using a multiple baseline design.
- Two or more target behaviours
- Stagger introduction of intervention
- Appropriate for documenting behaviours which are expected to be learned.
If the behaviours only change when the intervention is introduced, it is likely that it is the intervention that caused the change.
Think about your own client or the case example. Identify a second behaviour that you could monitor, and then target, during your intervention, in order to demonstrate that it is your intervention (as opposed to other factors) that is resulting in change in the targeted behaviours.
