Symptom Trajectory Approaches to Research

Ped-PRO-CTCAE evaluates pediatric cancer symptoms using patient or caregiver reports scored on a 0-to-3 scale across attributes like frequency, severity, and interference. 38 items are scored 0-3, where 0 = never (or equivalent) and 3 = all the time (or equivalent). Scores range from 0 to 114, with higher scores indicating worse symptoms. This score will be used to measure the trajectory of symptoms over time.

PROMIS Pediatric Global Health 7 is a 7-item survey used to measure overall physical, mental, and social health in children and adolescents. It is scored using a 5-point Likert scale, where 1 = poor and 5 = excellent. Scores range from 7 to 35, with higher scores indicating better global health.

PROMIS Pediatric Mobility is a 7-item questionnaire that evaluates self-perceived physical mobility and functioning in children and adolescents. It uses a 5-point Likert scale ranging from "Without no trouble" to "Not able to do". Raw scores range from 7 to 35. Raw scores are translated into normalized T-scores with a US population-level mean of 50 and a standard deviation (SD) of 10. A T-score of 50 represents average mobility for the general population. Scores above 50 mean better-than-average mobility, while scores below 50 indicate greater impairment.

PROMIS Physical Stress Experiences is an 8-item questionnaire designed to measure physical symptoms of stress in children and adolescents. It is scored by summing the raw item responses (ranging from 8 to 40) and converting that total into a standardized T-score. The raw score maps to a standardized T-score with a mean of 50 and a standard deviation (SD) of 10 for the general population. Higher T-scores reflect a greater level of physical stress.
