Informed consent: Too much of a good thing or not enough?

Informed consent is an essential aspect of the establishment of every professional relationship in which psychologists participate. When done effectively, it helps promote other individuals' autonomy, engages them in a collaborative process, and helps to reduce the likelihood of exploitation or harm, among a number of potential benefits. Yet, a number of challenges and dilemmas relevant to informed consent exist for psychologists. Three invited experts provide commentaries on issues raised, questions asked, and dilemmas posed that will, the authors hope, fully stimulate further consideration and discussion of these important issues. The commentaries also broaden the discussion of informed consent in all roles in which psychologists serve. Specific recommendations are made for practicing psychologists for the ethical and effective application of informed consent in their work.
