Abstract

Purpose

Patient-Reported Outcomes Measurement Information System (PROMIS) Pediatric forms measure symptoms and function of pediatric patients experiencing chronic disease by using the same measures. Comparability is one of the most important purposes of the PROMIS initiative. This study aimed to test the factorial structures of four symptom measures (i.e., Anxiety, Depression, Fatigue, and Pain Interference) in the original English and the Chinese versions and examine the measurement invariance of the measures across two cultures.

Methods

Four PROMIS Pediatric measures were used to assess symptoms, respectively, in Chinese (n = 232) and American (n = 200) children and adolescents (8–17 years old) in treatment for cancer or in survivorship. The categorical confirmatory factor analysis (CCFA) model was used to examine factorial structures, and multigroup CCFA was applied to test measurement invariance of these measures between the Chinese and American samples.

Results

The CCFA models of the four PROMIS Pediatric symptom measures fit the data well for both the Chinese and American children and adolescents. Minor partial measurement invariance was identified. Factor means and factor variances of the four PROMIS measures were not significantly different between the two populations.

Conclusions

Our results provide evidence that the four PROMIS Pediatric symptom measures have valid factorial structures and a statistical property of measurement invariance across American and Chinese children and adolescents with cancer. This means that the items of these measures were interpreted in a conceptually similar manner by two groups. They could be readily used for meaningful cross-cultural comparisons involving pediatric oncology patients in these two countries.
