Insights

The Patient-Reported Outcomes Measurement Information System (PROMIS) Pediatric Anger Scale was developed and validated. This new six-item scale effectively measures anger in children aged 8-17 for clinical research.

Area of Science:

  • Psychometrics
  • Pediatric Health
  • Outcome Measurement

Background:

  • The Patient-Reported Outcomes Measurement Information System (PROMIS) develops patient-reported outcome (PRO) instruments for clinical research.
  • The PROMIS pediatrics project focuses on developing PROs for children aged 8-17 across various health domains.

Purpose of the Study:

  • To evaluate the psychometric properties of the PROMIS Pediatric Anger Scale.
  • To develop a reliable and valid measure of anger in pediatric populations.

Main Methods:

  • A total of 759 participants (ages 8-17) were recruited from diverse settings.
  • Confirmatory factor analysis (CFA) assessed scale dimensionality and local dependence.
  • Item response theory (IRT) analyses were used to refine the scale and create a short form.

Main Results:

  • CFA confirmed the unidimensionality of the anger items.
  • Items with local dependence were removed, resulting in a six-item short form.
  • IRT analyses provided scaled scores and conditional standard errors for the PROMIS Pediatric Anger Scale, version 1.0.

Conclusions:

  • The study successfully calibrated anger items and established the PROMIS Pediatric Anger Scale, version 1.0.
  • This validated scale provides a valuable tool for assessing anger in pediatric clinical research.

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.
Oppositional Defiant Disorder01:30

Oppositional Defiant Disorder

A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.
