Clinician-Administered PTSD Scale for DSM-5 (CAPS)
The Clinician-Administered PTSD Scale for DSM- 5 (CAPS) was created in 2015 by government employees Weathers, Blake, Schnurr, Kaloupek, Marx and Keane. It is a 30-item structured interview designed to assess the severity of PTSD symptoms based on the DSM-5 criteria. There are 3 versions of the assessment: 1.) Past week version, 2.) Past month version, and 3.) Worst month version. The assessment is intended for adults, typically those age 18 and older.
Who Can Use?
According to the National Center for PTSD’s website, “The American Psychological Association’s ethical guidelines on psychological test instruments require advanced graduate level training in the administration and interpretation of psychodiagnostic assessment instruments. Thus, access to these measures requires proof of clinical status or research credentials.” The applicant is also asked to make clear their intended use of the assessment requested. Furthermore, students who are requesting the document for course papers are encouraged to use sample items or have their clinical professors make the request.

Multidimensional Inventory of Dissociation (MID)
The Multidimensional Inventory of Dissociation (MID) is a comprehenssive 218-item self-report measure designed to assess a wide range of dissociative symptoms. It is intended for use by mental health practitioners and researchers to evaluate dissociative experiences and symptoms in individuals. The MID includes detailed questions about various dissociative phenomena, such as amnesia, depersonalization, and identity alteration. Adminstration of the MID typically requires a clinician to guide the process, and it can be used to generate detailed reports and graphs for interpreting results.
Who Can Use?
The MID is intended to be used only by clinicians and researchers. To obtain a copy of the MID Interpretive Manual and MID Analysis, please fill out the request form at: https://www.mid-assessment.com/request-mid-analysis/.
