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.

Notes
Anxiety, Depression, and Pain all have eight items; thus, each has 32 item thresholds. Fatigue has 10 items and thus has 40 item thresholds.

It was listed the item stems of the original English version of PROMIS Pediatric (PROMIS Pediatric SF v1.0) Anxiety and Depression, Fatigue, and Pain Interference Symptom Short Forms. All items with 7-day recall period stated as “in the past seven days,” and a 5-point responses with the options never (0), almost never (1), sometimes (2), often (3), and always (4). In the updated PROMIS Pediatric Short Forms (PROMIS Pediatric SF v1.1 versions), the item 3460R1 and 3462R1 in Anxiety and item 3477R1 in Depression were deleted and replaced by new items, and the item 3506R1 in Anger was deleted.
