To ensure that trauma history was well captured, only participants who met the following criteria were included in the study sample: (1) at least one report from a measure administered to primary caregivers; (2) at least one report from each of the three measures administered to all child participants (Child PTSD Symptom Scale, Abuse Questionnaire, and Child Police Contact); and (3) reports from at least one of three measures administered to all child participants for greater than half the 8-year period (ages 10–17) during which they were administered, i.e. 5 or more years. Trauma data were available from a mean of 5.9 (SD=0.75) different measures (maximum possible=7). The mean number of years that reports from measures administered to all children were available was 7.7 (SD=0.70) (maximum possible=8).
