The American Pain Society is a national chapter of the International Association for the Study of Pain (IASP). Founded in 1973, IASP is the largest multidisciplinary international association in the field of pain, bringing together scientists, clinicians, health care providers, and policy makers to stimulate and support the study of pain and to translate that knowledge into improved pain relief worldwide. Currently IASP has more than 8,000 individual members from over 133 countries, 90 national chapters, and 19 special interest groups (SIGs).
IASP publishes the journal PAIN, which features reviews, original research articles, clinical notes, and letters on both clinical and basic sciences. The World Congress on Pain is the biannual scientific meeting of the society and brings together thousands of the world's leading experts on pain as they share their thoughts, research and findings on this critical topic.
