The LASC is a 43-item self-report measure of PTSD and associated
features. The LASC does not key to any specific trauma and inquires
about the presence of problems in the past month. The 17 DSM-IV
symptoms of PTSD are embedded among other items that assess more
general psychological distress. Items are rated on a 5-point scale
ranging from 0 ("no problem") to 4 ("extreme problem"). A
preliminary diagnosis of PTSD can be derived by using DSM-IV
criteria with a symptom counting toward diagnosis if it is rated at
2 or higher. In addition, a continuous measure of PTSD symptom
severity can also be computed by summing the ratings of the 17
items corresponding to the symptoms of PTSD. A sum of all 43 items
provides an index of global assessment of distress and adjustment
problems that may be a consequence of trauma exposure.
Sample Item
"Difficulty falling asleep." (Respondents are asked to rate how
much of a problem the item is for them.)
Versions
An LASC for adolescents is also available.
