Penn Inventory for Posttraumatic Stress Disorder (Penn Inventory)

Hammarberg, 1992

Description

The Penn Inventory is a 26-item self-report measure that assesses DSM-IV symptoms of PTSD. It can be used with clients with multiple traumatic experiences because symptoms are not keyed to any particular traumatic event. The response format resembles that of the Beck Depression Inventory (BDI) by having respondents endorse one statement from a series of four scaled sentences that best describes the degree, frequency, or intensity of their feelings during the past week.

Scores for each statements range from 0 to 3. The Penn does not assess all of the 17 DSM symptoms of PTSD and it includes items that are not directly related to DSM criteria (e.g., self-knowledge). The Penn yields a continuous total score (ranging from 0 to 78) reflecting severity of PTSD. A preliminary determination of PTSD diagnosis can be derived by using a cutoff score.

Sample Item

0 = I know someone nearby who really understands me.
1 = I'm not concerned whether anyone nearby really understands me.
2 = I'm worried because no one nearby really understands me.
3 = I'm very worried because no one nearby understands me at all.

(Respondents are asked to circle a number next to the one statement that best describes how they have been feeling.)
