Los Angeles Symptom Checklist (LASC)

King et al., 1995

Description

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.
