Insights
This study evaluated the Patient-Reported Outcomes Measurement Information System (PROMIS) pediatric items for measuring health in children. The PROMIS pediatric item banks provide a robust tool for assessing various health domains in diverse pediatric populations.
Area of Science:
- Pediatric Health Measurement
- Health Outcomes Research
- Psychometrics
Background:
- Patient-reported outcomes are crucial for assessing pediatric health.
- Existing measures may not adequately capture the experiences of diverse child populations.
- The Patient-Reported Outcomes Measurement Information System (PROMIS) aims to standardize health outcome measurement.
Purpose of the Study:
- To evaluate the measurement characteristics of PROMIS pediatric items.
- To establish psychometrically sound item banks for pediatric health assessment.
- To assess the utility of PROMIS in a large, diverse pediatric sample.
Main Methods:
- Large-scale administration of PROMIS pediatric items to children aged 8-17.
- Children completed test forms including PROMIS items across six domains: physical function, emotional distress, social role relationship, fatigue, pain, and asthma.
- Data collected from 4,129 children between January 2007 and May 2008.
Main Results:
- The study enrolled 4,129 children (51% female, 55% aged 8-12, 42% minority race, 17% Hispanic).
- Approximately 35% of children had consulted a clinician for a chronic illness within six months prior to enrollment.
- PROMIS items demonstrated suitability for measuring various health domains in this pediatric cohort.
Conclusions:
- Final PROMIS pediatric item banks were developed for physical function (52 items), emotional distress (35 items), social role relationships (15 items), fatigue (34 items), pain (13 items), and asthma (17 items).
- Initial calibration data from a diverse pediatric population with varying health states and backgrounds support the generalizability of PROMIS measures.
- These item banks provide a foundation for reliable and valid pediatric health outcome assessment.
Purpose:
This paper describes a large-scale administration of the Patient-Reported Outcomes Measurement Information System (PROMIS) pediatric items to evaluate measurement characteristics.
Methods:
Each child completed one of seven test forms containing items from a pool of 293 PROMIS items and four legacy scales. PROMIS items covered six domains (physical function, emotional distress, social role relationship, fatigue, pain, and asthma).
Results:
From January 2007 to May 2008, 4,129 children aged 8-17 were enrolled. The sample was 51% female, 55% aged 8-12, 42% minority race and 17% were Hispanic ethnicity. Approximately, 35% of the children participating in the survey consulted a clinician for a chronic illness diagnosis or treatment within 6 months prior to study enrollment.
Conclusions:
The final PROMIS pediatric item banks include physical function (n = 52 items), emotional distress (n = 35 items), social role relationships (n = 15 items), fatigue (n = 34 items), pain (n = 13 items), and asthma (n = 17 items). The initial calibration data were provided by a diverse set of children with varying health states (e.g., children with a variety of common chronic illnesses) and racial/ethnic backgrounds.

Random sampling is a method where each member of the population has an equal chance of being selected for the sample. It involves selecting individuals randomly, often using random number generators or lottery-type methods. For example, when analyzing the properties of a...
