The American Psychological Association's Ethical Principles of Psychologists and Code of Conduct requires therapists to be mindful of diversity, which includes religious diversity, says Plante (psychology, Santa Clara U.). Therefore practitioners can no longer ignore religious and spiritual concerns among their clients. He offers psychologists and other mental health professionals advice on using spirituality and wisdom from the religious traditions to benefit their clients.

Other topics include assessment issues, consultation with religious professionals, and best practices in action. Annotation ©2009 Book News, Inc., Portland, OR (booknews.com)
