The term "child sexual abuse accommodation syndrome" (CSAAS) was initially coined by psychiatrist Roland Summit in 1983 in an effort to understand the various ways children react to sexual abuse. From an evidentiary perspective, not all states recognize CSAAS as admissible. Indeed, CSAAS is not recognized by the American Psychiatric Association or the American Psychological Association. In California, expert testimony regarding CSAAS is admissible.  A recent case, People v. Mason, sheds light on the use of CSAAS in court. Note that Mason is an unpublished opinion.
