title: Assessing mental health outcomes of political violence and civil unrest in Peru.
abstract: BACKGROUND
  Sustained political violence (SPV) may have long-term effects.
  
  
  OBJECTIVE
  To assess mental and residual effects of exposure to SPV. To validate a post-traumatic stress disorder (PTSD) assessment tool in Quechua-speaking Peru.
  
  
  METHODS
  Survey of 373 individuals aged 15 and over using the General Health Questionnaire (GHQ-12), Hopkins Symptom Checklist (HSCL-25) and a Trauma Questionnaire (TQ), derived from the Harvard Trauma Questionnaire. Sociodemographics were recorded. Reliability was assessed. Data reduction used factor analysis and modelling multiple regressions.
  
  
  RESULTS
  A quarter of the sample had symptoms compatible with PTSD. Questionnaire reliability ranged from 0.81 to 0.89. Factor analysis confirmed high construct validity for TQ and HSCL-25. Modelling showed a strong association of PTSD-related symptoms and expressions of distress with the degree of exposure to SPV, especially among returnees.
  
  
  CONCLUSIONS
  Long-term consequences of exposure to SPV take the form of PTSD, anxiety and depressive disorders, and culturally formulated expressions of distress. Some implications for clinicians are discussed.
