Our History

The Treatment Research Institute (TRI) was founded in 1992 as a 501(c)(3) not-for-profit organization in Pennsylvania. Over the past twenty years, TRI’s core mission has been to apply research to improving substance abuse policies and programs.  The organization is extremely well-regarded as a leader in translating developmental research into practical applications in the substances use arena.  It is known as the ‘home’ of the Addiction Severity Index (ASI), which is one of the most widely utilized assessment tools in the field.  Instruments developed by TRI are among the most widely utilized by clinicians, researchers and the justice system throughout the world.

Concurrent with the effort to develop better tools, the TRI has been a significant ‘thought leader’ in evaluating the many practical barriers that prevent absorption of new instruments, methods and information into everyday use.   Indeed the founding of the Treatment Research Institute was a purposeful attempt to coordinate study of both addiction science; and practical application of that science to clinical and policy decision making.  The organization remains deeply committed to finding practical, science-based approaches to addressing an array of addictions-related public health problems
