Harold G. Koenig is a psychiatrist on the faculty of Duke University.
His ideas have been covered in Newsweek and other news media with regard to religion, spirituality and health, a focus of some of his research and clinical practice.
Templeton Foundation has provided great financial support to his activities.
[2] In a cooperation with Raphael M. Bonelli from Sigmund Freud University Vienna he undertook the first systematic evidence based analysis on the connection between mental disorders and religion.
The researchers conclude that there is good evidence that religious involvement is correlated with better mental health in the areas of depression, substance abuse, and suicide; some evidence in Stress-related disorders and dementia; insufficient evidence in bipolar disorder and schizophrenia, and no data in many other mental disorders.
