Relationship between parental stress and post-traumatic stress disorder: The moderating effect of visitation restrictions in paediatric intensive care units during COVID-19

Abstract

Background: Visitation restrictions due to COVID-19 kept parents from being with their children who were hospitalized in the PICU and from meeting with professional staff.Aim: This study examined the moderating effect of COVID-19-induced visitation restrictions on the relationship between stress and post-traumatic stress disorder in parents of children admitted to the paediatric intensive care unit.Study Design: We conducted a descriptive, exploratory study involving 93 parents of children hospitalized in the paediatric intensive care unit using the Korean version of the Parental Stressor Scale: Paediatric Intensive Care Unit and the Revised Impact of Events Scale. Descriptive, Pearson's correlation, and logistic regression analyses were used to investigate the data. Self-reported survey questionnaires were provided for parents to complete in a separate area of the outpatient clinic when they visited for follow-up care after their children were discharged from the paediatric intensive care unit.Results: Mothers showed significantly higher post-traumatic stress disorder scores than fathers. The relationship between all the sub-domains of perceived stress and post-traumatic stress disorder was statistically significant. Visitation restrictions because of the COVID-19 pandemic had significant moderating effects on the relationship between perceived parental stress and post-traumatic stress disorder. Moreover, the moderating effects of COVID-19 were exhibited when the two sub-domains-hyperarousal and intrusion-were investigated.Conclusions: Paediatric intensive care unit visitation may be an important intervention for parental post-traumatic stress disorder. Parental visitation should be enabled, and alternative interventions should be developed in situations where visitation is prohibited.Relevance to Clinical Practice: It is necessary to develop and apply various and effective alternatives visitation that can prepare hospitals for visiting restrictions during pandemic situations which could emerge in the future.
