“…Each item is a word or phrase that is rated on a 5-point Likert scale ranging from 0 (no problem) to 4 (extreme problem), reflecting the extent to which the particular symptom was a problem for the respondent during the past one month. The LASC is a widely used PTSD evaluating instrument (e.g., Eriksson, Kemp, Gorsuch, Hoke, & Foy, 2001;Scott, 2007;Stander, Merrill, Thomsen, & Milner, 2007), and reliability and validity of this scale have been well documented (Orsillo, 2001). The Chinese version of the Los Angeles Symptom Checklist was adapted by a two-stage process of translation and reverse translation.…”
