An investigator planning to study behavioral changes during alcohol intoxication will pay subjects $600 for 6 hours of testing that includes drinking a moderate level of alcohol and completing several written questionnaires. He plans to recruit college students taking his courses, as well as economically disadvantaged and homeless people. Which of the following is the most important for the investigator to address before submitting the protocol to the IRB?

Potential undue influence or coercion of subjects

Explanation:

Coercion means influencing or making somebody to act or do something by forceful means or by threatening them.

In the context, a researcher requires human subjects to investigate or do a study on his research on the affect of alcohol intoxication in the behavioral changes of them. For this he will pay $600 to the subjects  for testing them for 6 hours.

Thus before submitting the protocol to the Institutional Review board, (IRB), he must be careful to note that none of his subjects either influenced forcefully or threaten to participate in his research work.
