Reliability and Validity of the Korean Version of the Lifetime Stressor Checklist-Revised in Psychiatric Outpatients with Anxiety or Depressive Disorders

Purpose Traumatic events and adverse stressful experiences are major etiological factors in a wide variety of physical and mental disorders. Developing psychological instruments that can be easily administered and that have good psychometric properties have become an integral part for research and practice. This study investigated the reliability and validity of the Korean version of the Lifetime Stressor Checklist-Revised (LSC-R) in a consecutive sample of psychiatric outpatients. The LSC-R is a 30-item self-reporting questionnaire examining lifetime traumatic and non-traumatic stressors.
