Insights

The Patient-Reported Outcomes Measurement Information System (PROMIS) developed new anxiety and depressive symptom item banks for children aged 8-17. These validated tools offer efficient assessment of pediatric mental health-related quality of life.

Area of Science:

  • Pediatric Psychology
  • Psychometric Measurement
  • Health Outcomes Research

Background:

  • The Patient-Reported Outcomes Measurement Information System (PROMIS) aims to create robust self-reported item banks for clinical research.
  • PROMIS pediatric project focuses on developing item banks for children aged 8-17 across various health domains.

Purpose of the Study:

  • To describe the psychometric properties of the anxiety and depressive symptom item banks for pediatric populations.
  • To develop and calibrate PROMIS pediatric instruments for efficient health-related quality of life assessment.

Main Methods:

  • Recruited 1,529 participants in school and clinic settings.
  • Utilized hierarchical confirmatory factor-analytic models (CFA) and Item Response Theory (IRT) analyses.
  • Administered anxiety (18 items) and depressive symptoms (21 items) across two test forms.

Main Results:

  • CFA confirmed anxiety and depressive symptoms as distinct constructs representing negative affect.
  • Items with local dependence and differential item functioning (DIF) were removed, resulting in 15 anxiety and 14 depressive symptom items.
  • Presented psychometric differences between short forms and simulated computer adaptive tests.

Conclusions:

  • Developed and calibrated PROMIS pediatric anxiety and depressive symptom item banks (version 1.0).
  • These item banks provide efficient assessment of pediatric mental health-related quality of life.
  • The study establishes validated instruments for measuring anxiety and depression in children.
