I am not familiar with the book, however, in therapy, I use a 1-2-3 count with a bit of a twist. I state the desired behavior. If no appropriate response, I begin counting - 1. I restate the desired behavior. If no indication of change, I ask, Do you need help? Then add - 2. When I say 3, I provide immediate even sudden hand over assist to get the job done.
This works best for tasks that I can physically assist in the action - such as come here, sit down, or get the [insert object]. I speak matter of factly giving direct eye contact and attention. I pause several moments between numbers to allow time for compliance. The physical assist is not in a friendly coddling manner, but rather directed and brisk. As soon as the desire action is completed I respond with "thank you" or "good job" and proceed with a smile as if nothing unusual has happened.
For a school aged child who has a better concept of time, a 3 strikes version may be useful. A child is trained that everyone makes mistakes and acts inappropriately at times and this system is explained. Bad or inappropriate behavior is confronted simply in a soft voice with the statement: That's number one. If bad behavior continues or is repeated at anytime during the day, the child is prompted with: That's number two. If the violation occurs once again during the day, the predetermined consequence is enforced. This will be different depending on the child. It may be a loss of privileges or other predetermined actions.
Each day begins with a new opportunity and even if there were 2 strikes the day before, the slate is wiped clean. Three new strikes are allowed every day.
