Clinician-Administered PTSD Scale for Children and Adolescents (CAPS-CA)
Nader et al., 1996
Description:
The CAPS-CA is a 33-item clinician-administered PTSD scale for youths aged 8 to 18 years. It is a modified version of the CAPS. Items were modified to make them age appropriate and picture response options were added. Practice questions help familiarize children with the assessment. The Life Events Checklist is used to identify traumatic events.
Like the CAPS, the CAPS-CA measures the frequency and intensity of symptoms associated with the 17 DSM-IV PTSD symptoms, as well as the impact of those symptoms on such aspects of functioning as overall distress, coping skills, and impairment. In addition to current and liferime dignoses, items assess overall severity, validity of ratings, associated symptoms, and coping strategies.
Items are scored on 5-point frequency (e.g., from 0 = "None of the Time" to 4 = "Most of the Time") and 5 point intensity rating scales (e.g., from 0 = "Not a Problem" to 4 = "A Big Problem, I Have to Stop What I Am Doing") for the past month.
Sample Item: B2:
Recurrent distressing dreams of the event
Frequency:
Did you have dreams about (EVENT)?
IF YES: Can you tell me about the dreams? [ASK THE CHILD TO DESCRIBE BOTH GOOD AND BAD DREAMS] Did you have dreams like this before (EVENT)? [IF YES, ASK:] (How much of the time did you have dreams like that before [EVENT]?)
In the last month did you have any bad dreams?
IF YES: Can you tell me more about the dreams? Did you have dreams like this before (EVENT)? [IF YES, ASK:] (How much of the time did you have dreams like that before [EVENT]?)
How much of the time did you have dreams like that in the past month/ (LIFETIME WORST MONTH)?
0 None of the time
1 Little of the time, once or twice
2 Some of the time, once or twice a week
3 Much of the time, several times a week
4 Most of the time, daily or almost every day
Intensity:
In this past month / (LIFETIME WORST MONTH), how much did the bad dreams bother you? Did they make you wake up? [IF YES, ASK:] (What were you doing when you woke up? How did you feel? When you woke up, were you crying, yelling, sad, or scared? Could you go back to sleep after your dreams? Were you out of bed?)
0 Not at all
1 A little, mild minimal distress, may not have awoken
2 Some, moderate, awoke in distress but readily returned to sleep
3 A lot, severe, considerable distress, difficulty returning to sleep
4 A whole lot, extreme, incapacitating distress, did not return to sleep
Versions:
The CAPS-CA was based on the Clinician-Administered PTSD Scale developed for use with adults.
