This depends on how motivated the patient is and if there are other psychological problems in the patient and/or family. Dr. Lazarus tries to take on only patients whom he thinks he can help. If the child is otherwise emotionally well, then significant improvement usually occurs after only two or three visits.
If patients are not ready to learn this technique on the first visit, Dr. Lazarus will encourage them to return when they are ready. Some patients need additional therapy or counseling, for example, from a psychiatrist, psychologist or other mental health professional.
For bio-behavioral problems, one can never predict how long change will take. That is why Dr. Lazarus screens patients carefully, and why it is extremely important for the family to answer all of his questions openly and honestly.
