The idea of dosing for the most effective response has resulted in a new empiricism toward prescribing for children. As if to counter this, chapter 3, "Clinical Aspects of Child and Adolescent Psychopharmacology," describes how to take a history from a child and the child's family, how to place the information in context, and how to begin to think systematically about prescribing. It contains many interesting tables, including one that lists behavioral variables that are amenable to pharmacotherapy and another that lists considerations when choosing a medication. This chapter also subtly suggests that despite the newness of child psychopharmacology, there is a standard of care. It challenges the use of empirical prescribing by proposing a more formal strategy.
