Insights

A new scale, the Children's Critical Illness Impact Scale (CCIIS), was developed to measure psychological distress in school-aged children after pediatric intensive care. This validated tool helps identify children needing support to promote healthy development.

Area of Science:

  • Pediatric Critical Care Medicine
  • Child Psychology
  • Health Outcomes Research

Background:

  • Pediatric critical care necessitates addressing psychological distress in children post-intensive care.
  • Existing measures for psychological outcomes in these children are limited.
  • Ethical considerations require validated tools to assess post-hospitalization psychological sequelae.

Purpose of the Study:

  • To develop and validate the Children's Critical Illness Impact Scale (CCIIS).
  • To create a reliable measure for posthospitalization psychological distress in children aged 6-12 years.
  • To provide a tool for assessing the impact of pediatric intensive care unit (PICU) hospitalization.

Main Methods:

  • A two-phase measurement development study: item generation and scale formatting, followed by item reduction and revisions.
  • Qualitative data from focus groups and interviews with children, parents, and healthcare professionals informed item generation.
  • Content validity was assessed by children and healthcare professionals, with a content validity index of 0.87.

Main Results:

  • Five key domains identified: worries, fears, friends and family, sense of self, and behaviors.
  • The final Children's Critical Illness Impact Scale (CCIIS) comprises 23 items.
  • The scale demonstrated good content validity, interpretability, and usability, with older children preferring written items and younger children potentially benefiting from a pictorial version.

Conclusions:

  • The Children's Critical Illness Impact Scale (CCIIS) is a novel, content-valid self-report measure for school-aged children post-PICU.
  • The CCIIS is specifically relevant for assessing psychological distress in this population.
  • Accessible and developmentally appropriate measures like the CCIIS are crucial for identifying at-risk children and supporting their healthy growth and development.
