Dr. Klassen Presents DSM-5 at #GrandRounds

On January 16, Dr. Phil Klassen, Vice-President of Medical Affairs at Ontario Shores, provided an update on the last version of the Diagnostic and Statistical Manual of Mental Disorders (DSM) during his presentation at Grand Rounds.

DSM-5 was released in May, 2013 and Dr. Klassen expects an updated version to follow within the next few years.

Grand Rounds

The DSM is the tool used to diagnose mental disorders, which guides treatment decisions and informs prognosis.

In highlighting some of the changes in the latest DSM version, Dr. Klassen pointed to greater transparency within the tool and noted revisions were based on research and consensus information.

Dr. Klassen noted reliability as a key element of the latest DSM version.  Some factors impacting the reliability of DSM are language barriers and diagnosis based on a single interview. The DSM, which is typically more reliable in diagnosing adults than children, is more effective when an individual has been interviewed more than once.
