Insights

This study developed patient-reported outcome (PRO) measures for children unable to self-report. The new PROMIS pediatric proxy-report item banks provide reliable data for children with chronic illnesses.

Area of Science:

  • Pediatric Health Outcomes Research
  • Psychometrics
  • Clinical Assessment

Background:

  • Pediatric self-report is the standard for patient-reported outcomes (PRO).
  • Proxy-reports are necessary when children cannot self-report due to age, cognitive impairment, or illness.
  • Development of the Patient Reported Outcomes Measurement Information System (PROMIS) pediatric proxy-report item banks is crucial for comprehensive child health assessment.

Purpose of the Study:

  • To describe the development of PROMIS pediatric proxy-report item banks.
  • To generate item parameters for proxy-reports across key pediatric domains.
  • To ensure reliable PRO data collection for children unable to self-report.

Main Methods:

  • PROMIS pediatric self-report items were adapted into proxy-report items.
  • Cognitive interviews with 25 caregivers assessed item clarity and usability.
  • A large-scale survey (n=1548 dyads, n=432 for younger children) collected data from caregivers and children (ages 8-17).

Main Results:

  • Proxy-report items were generally well-understood, though some items posed challenges for proxy respondents.
  • The study sample comprised diverse caregivers (85% female, 64% Caucasian) of children with chronic conditions, primarily asthma.
  • PROMIS proxy sample performance was comparable or superior to normative samples on other validated instruments.

Conclusions:

  • The PROMIS pediatric proxy-report item banks were developed using data from a diverse caregiver population.
  • Item banks cover critical domains: physical function, emotional distress, social peer relationships, fatigue, pain interference, and asthma impact.
  • These banks provide essential tools for measuring pediatric patient-reported outcomes when proxy-reporting is required.

Three Developmental Domains

Human development is typically examined across three main domains: physical, cognitive, and socio-emotional. These domains represent the significant areas of change and continuity throughout the lifespan, from infancy to late adulthood.
Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...
Self-Report Tests of Personality01:22

Self-Report Tests of Personality

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.
Methods of Documentation III: PIE01:21

Methods of Documentation III: PIE

Problem-intervention-evaluation (PIE) is a systematic approach to documentation used in healthcare settings for clinical decision-making and patient care planning. It is a structured approach to organizing patient data based on problems, interventions, and evaluations. Here's a breakdown of its key features and considerations:
Methods of Documentation II: POMR01:26

Methods of Documentation II: POMR

The Problem-Oriented Medical Record (POMR) revolutionized medical record-keeping by introducing a systematic approach focusing on the patient's problems rather than merely listing symptoms. Dr. Lawrence Weed's introduction of this method in the 1960s marked a significant advancement in medical documentation. The POMR framework consists of four key components: the database, problem list, plan of care, and progress notes.

Types of Reports III: Telephone and Verbal Reports

Telephone and Verbal Reports in healthcare settings are two communication methods for conveying therapeutic instructions from healthcare providers to nurses or other healthcare staff.
