Measure

Description

Scales/Factors

Anxiety Disorders Interview Schedule-Revised (ADIS-R) (DiNardo and Barlow, 1988)

  • Assesses anxiety and affective disorders

  • Structured diagnostic interview

  • Likert rating scales

 

Clinician Administered PTSD Scale (CAPS) (Blake et al., 1990)

  • Most widely used measure of PTSD (Weathers et al., 2001)

  • Assesses all DSM-IV PTSD symptoms, impact on functioning, response validity, lifetime diagnosis, and overall PTSD severity

  • Original version, based on DSM-III-R criteria: CAPS-1 (current and lifetime diagnosis, symptoms over past, or worst month since trauma) CAPS-2 (symptoms over past week for repeated assessments)

  • DSM-IV revision with user feedback incorporated: CAPS-1 renamed CAPS-DX (diagnostic version) and CAPS-2 renamed CAPS-SX (symptom status version)

  • Current version, CAPS, combined CAPS-1 and CAPS-2

  • Structured interview

  • 45–60 minute administration by trained (para)professionals

  • 34 items (17 items on frequency, 17 items on intensity)

  • Dichotomous (diagnosis present/ absent) and continuous assessment

  • Five-point Likert ratings of symptom severity (0–4)

  • Time frames for assessment include: past week, month, or worst month since trauma

  • Initially validated on combat veterans, subsequently applied in a wide variety of trauma populations including victims of rape, crime, motor vehicle accidents, incest, torture, and cancer (Weathers et al., 2001)

  • Confirmatory factor analyses supported fit of two-factor structure (Buckley et al., 1998):

  • Intrusion and avoidance, hyperarousal, and numbing

  • Confirmatory factor analyses comparing solutions suggested an oblique 4-factor, first-order solution as the best fit to data (King et al., 1998):

  • Reexperiencing, effortful avoidance, emotional numbing, hyperarousal
