AbstractThis study aimed to explore children's experiences and memories of the pediatric intensive care unit (PICU) and identify the relative importance of premorbid, trauma, and cognitive/affective variables associated with acute posttraumatic stress symptoms (PTSS). Participants were 95 children aged 6-16 years admitted to the PICU and their parents. Children completed questionnaires and an interview assessing PTSS, peritrauma affect, and their memory of the admission 3 weeks following discharge. Medical data were extracted from patient charts. Premorbid and demographic data were provided by parent questionnaire. Most children remembered some aspects of their admission. Younger age, admission for traumatic injury (rather than non-injury-related reasons), and cognitive/affective factors including confusion, peritrauma panic, and sensory memory quality were associated with acute PTSS. Age and traumatic injury accounted for 18% of the variance in PTSS (p < .01). The addition of cognitive/affective variables increased the explained variance to 38% (p < .001). Child age did not moderate the effect of cognitive/affective variables on PTSS. This study demonstrates that objective indicators of disease severity do not adequately explain the high prevalence of PTSS in children following PICU admission. It also suggests that subjective, cognitive factors such as the way children process and remember a PICU admission are very important in the onset of PTSS.
