Exploratory model of parental stress during children's hospitalisation in a paediatric intensive care unit.

Objectives: This exploratory study (a) examined pre-existing and peri-trauma risk factors of parental stress during a child's PICU hospitalisation using the Integrative Trajectory Model of Paediatric Medical Traumatic Stress and (b) identified the type of PICU-related stressors that predicted parental stress during the child's PICU hospitalisation.

Methods: A cross-sectional, descriptive correlational design with 81 parents of children admitted 48 or more hours to a Paediatric Intensive Care Unit (PICU). Questionnaires measured parent's and child's demographic and clinical characteristics and parent-reported stressors using the Parental Stressors Scale (PSS:PICU). Analysis included descriptive statistics and multiple linear regression analyses with simultaneous predictor entry.

Results: Male parents tended to be significantly more stressed than female parents. Parental stress was significantly increased when parents had one or more stressful life events one-month prior to PICU admission, when the child required ventilatory support, or the child had a cardiovascular diagnosis. Parental stress was also predicted by the child's appearance, procedures, child's behaviour, behaviour of staff, and parental role.

Conclusion: Nurses are in a prime position to identify parents at potentially high risk for psychological morbidity when they know a parent has had a stressful life event prior to admission, has a child with a cardiovascular diagnosis or requires ventilatory assistance. Nurses can diminish parental stress by interpreting the child's appearance for parents, helping parents understand the procedures being done for the child, interpreting the child's behaviour, explaining the staff's behaviour, and assisting parents to define their parental role during the child's hospitalisation.
