Journals that require IRB approval as a matter of policy In a number of questions raised here, it has been implied / asserted that research involving human subjects which has not received IRB approval cannot be published. In my own area of research (which is not experimental), I know of no evidence for such a restriction by journal policy. I am therefore curious about the mechanics and nature of such restrictions. Are there journals with explicit policies of this type? I would especially be interested to know of examples in areas outside of the social sciences and medicine. I do, however, want to restrict the question to reputable journals (leaving it up to the experts to make the distinction).

There are a number of underlying questions that motivate this question, so I'm looking for the tools to answer them myself. For instance, in two highly-regarded experimental journals in my field, there is no public statement about requiring IRB approval, so I wonder where the enforcement comes in, and whether authors (especially independent researchers) are given fair notice prior to submission. Right now, I just want to know where there are (non-biomedical) journals that positively do have such a policy.
For example, here is the bioethics policy for the Nature journals.  It includes the sentence:


  For experiments involving human subjects, authors must identify the committee approving the experiments, and include with their submission a statement confirming that informed consent was obtained from all subjects.
