Typically, trauma tests and questionnaires are designed for a specific population in mind which may preclude certain clinical features or co-occurring populations. The PTSI-R was designed to avoid these issues and assess for other manifestations of trauma, such depression. Another unique feature of the PTSI-R is that it includes previously excluded populations such as sexual addiction. The PTSI-R is not tied to any particular clinical theoretical orientation such as psychoanalytic, humanistic, or behavioral, and instead employs the most current research in the field of trauma from an interdisciplinary social neuroscience perspective.
