Online Enhancements
It was challenging to determine what to incl ude in the print version of DSM-5 to be most
clinically relevant and useful and at the same time maintain a manageable size. For this
reason, the inclusion of clinical rating scales  and measures in the pr int edition is limited to
those considered most relevant. Additional as sessment measures used  in the field trials
are available online (www.psychiatry.org/dsm5 ), linked to the relevant disorders. The
Cultural Formulation Interview, Cultural Fo rmulation Interview—Informant Version, and
supplementary modules to the core Cultural Formulation Interview are also available on-
line at www.psychiatry.org/dsm5.
DSM-5 is available as an online subscription  at PsychiatryOnline.org as well as an e-
book. The online component contains modules and assessment tools to enhance the diag-
nostic criteria and text. Also available online is a complete set of supportive references as
well as additional helpful information. The organizational structure of DSM-5, its use of
dimensional measures, and compatibility with ICD codes will allow it to be readily adapt-
able to future scientific discoveries and refinements in its c linical utility. DSM-5 will be an-
alyzed over time to continually assess its validity and enhance its value to clinicians.
