Commentary: Dr. Mercer has devoted her career to protecting children from harmful psychotherapeutic practices. Now, in Alternative Psychotherapies, she gives readers the tools for evaluating a wide range of unconventional therapies themselves. Once again, Dr. Mercer has done a great public service in writing this book and helping to ensure that individuals in need will receive safe and effective treatments and steer clear of potentially dangerous ones.
