PROVIDENCE, R.I. (AP) - A classic guide for lawyers about the science behind expert courtroom testimony by mental health professionals has been updated by a University of Rhode Island professor.

The university says Oxford University Press recently released a new version of "Coping with Psychiatric and Psychological Testimony" that was brought up to date by clinical psychology professor David Faust.

The reference book was originally written by the late lawyer and psychologist Jay Ziskin, who was credited with helping lawyers challenge psychiatric and psychological testimony.

The university says the book was published in 1970 and last updated in 1995. Faust worked with Ziskin on the fourth edition.

The book provides lawyers with practical guidance, scientific background and techniques for defending or attacking testimony.
