Interaction includes communication or interpersonal contact between investigator and subject.
Research means a systematic investigation, including research development, testing and evaluation designed to develop or contribute to generalizable knowledge. Activities which meet this definition constitute research for purposes of this policy whether or not they are conducted or supported under a program which is considered research for other purposes. For example, some demonstration and service programs may include research activities. Certain human subject research may be declared by the IRB to be exempt from regulation, and thus, exempt from IRB review and oversight. Turn-around time on expedited reviews is sometimes hours, but rarely exceeds a few days unless the chair has difficulties with the informed consent process or other issues.
