For more than 30 years, Bowling Green State University Psychology Professor Kenneth Pargament has been studying the connection between religion and mental health. Only in recent years has there been a growing awareness and understanding among Pargament's mental health colleagues of the impact -- for better or worse -- that spirituality can have on patients. Pargament's most recent book, Spiritually Intergrated Psychotherapy: Understanding and Addressing the Sacred, published by Guilford Press, explores the topic.
