La Lista de Verificación del Trastorno de Estrés Postraumático (PCL) en víctimas del terrorismo: análisis comparativo de las propiedades psicométricas de su aplicación telefónica frente a presencial

Introduction and objectives. In many situations, such as confinement situations caused by the COVID-19 pandemic, it is not possible to administer psychological instruments in person, as originally contemplated in their development. However, the mode of administration can affect the psychometric properties of instrument scores. The PTSD Checklist (PCL) is one of the most widely used instruments for assessing the symptoms of posttraumatic stress disorder (PTSD) in person. This study is the first research that has analyzed and compared the factorial structure, the internal consistency, the validity of contrasted groups, the diagnostic validity, and the nomological validity of scores on the PCL administered in person and by telephone.
