Los Angeles Symptom Checklist (LASC) K ing, King, Leskin, & Foy, 1995 The LASC is a 43-item self-report measure assessing symptoms of PTSD in adults and adolescents for screening and diagnosis purposes. The LASC consists of items corresponding to the DSM-IV criteria for PTSD and items assessing distress and adjustment problems. Each item is rated on a scale from zero (“not a problem”) to four (“extreme problem”). A preliminary diagnosis of PTSD can be determined using the 17 items within the scale that correspond to the DSM-IV criteria for PTSD. A response counts towards the preliminary diagnosis if rated as a 2 or higher. The LASC was designed to be administered in 10-15 minutes. The LASC demonstrates excellent internal consistency for the 17 items correlated with DSM-IV criteria (α = .94) and the total score (α = .97). For use in adolescents, the LASC has demonstrated excellent internal consistency for the 17 items associated with DSM-IV criteria (α = .90) and the total score

  Los Angeles Symptom Checklist ( LASC; King, King, Leskin, & Foy, 1995). The LASC is a 43-item self-report measure assessing symptoms of PTSD in adults and adolescents.  The LASC can be used as a screening and diagnostic tool (King et al., 1995). The LASC consists of items corresponding to the DSM-IV criteria for PTSD and items assessing distress and adjustment problems. Sample items include, “Vivid memories of unpleasant prior experiences” and “Waking early in the morning.” Each item is rated on a scale from zero (“not a problem”) to four (“extreme problem”). A preliminary diagnosis of PTSD can be determined using the 17 items within the scale that correspond to the DSM-IV criteria for PTSD.  A response counts towards the preliminary diagnosis if it is rated as a 2 or higher. The LASC was designed to be administered in 10-15 minutes (Orsillo, 2001). The LASC demonstrates excellent internal consistency for both the 17 items correlated with DSM-IV criteria (α = .94) and for the tot
