#' Post-traumatic stress disorder symptoms of Wenchuan earthquake survivors
#'
#' A data set containing items measuring symptoms of posttraumatic stress 
#' disorder (PTSD) \insertCite{McNallyEtAl_2015}{bgms}. Participants were 362 
#' Chinese adults who survived the Wenchuan earthquake and lost at least one 
#' child in the disaster. PTSD symptoms were reported using the civilian version 
#' of the Posttraumatic Checklist, which consists of 17 items, each assessing 
#' one of the DSM-IV symptoms of PTSD. Participants rated each item on a 
#' five-point scale ranging from ``not at all'' to ``extremely'' to indicate how 
#' much the symptom bothered them in the past month.
