NOTE: The following information pertains to the CAPS for DSM-IV. Training materials for CAPS-5 are under development and will be added as soon as available. There is scoring information within the CAPS-5 instrument. If you are using the CAPS-5 without prior CAPS experience, the training materials below are helpful until new materials are developed. The most notable change is that the CAPS-5 has combined item ratings of "Frequency" and "Intensity" into a single 0-4 "Severity" rating.
The Clinician-Administered PTSD Scale, or CAPS, is the "gold standard" for PTSD assessment and diagnosis for both military Veteran and civilian trauma survivors. There are technical manuals and CD-ROM training tools available for learning to administer a CAPS or CAPS-CA (version for children and adolescents).

CAPS and CAPS-CA Manuals are available from:
Western Psychological Services (WPS)*.
Search their online list of available products for CAPS (which includes the CAPS-CA). For both the CAPS and the CAPS-CA, there is an interview booklet, interview guide, and technical manual available, as well as a continuing education (CE) questionnaire and evaluation form for the CAPS.
Independent Study materials are designed to teach a set of essential competences for administering the CAPS. It is assumed that users will possess basic knowledge about trauma and its effects. No attempt is made to provide systematic instruction about PTSD in this training material.
It is also assumed that clinicians will be trained in the general skills required to conduct interviews (e.g., skills for communicating empathy or establishing rapport) as well as those important in managing the intense emotions that may be experienced by those suffering with PTSD.
