Resnik DB, Peddada S, Brunson W Jr. Research misconduct policies of scientific journals. Account Res 2009;16:254-267.
A random sample of 399 journals were contacted, asking for details of policies on research misconduct. Of the 197 journals that responded, 55% had a policy, but most policies didn't define misconduct and most weren't created by the journal. The existence of a misconduct policy was slightly positively associated with the journal impact factor.
