Ten Considerations for Integrating Patient-Reported Outcomes into Clinical Care for Childhood Cancer Survivors

Simplified Chinese version of the PROMIS Pediatric-25 profile: A validation study among cancer children

PURPOSE

Pediatric cancer is a significant health concern in China, and evaluating the impact of cancer and its treatment on the well-being of young patients is essential for both clinical care and research purposes. This study aimed to psychometrically validate the Patient-reported Outcomes Measurement Information System Pediatric-25 Profile (PROMIS-Pediatric-25) among Chinese children with cancer.

DESIGN AND METHODS

We enrolled a group of 114 children living with cancer between the ages of 8 and 17. Each participant completed questionnaires that covered sociodemographic and clinical information and the PROMIS-Pediatric-25. The floor and ceiling effect was examined. Cronbach's alpha and split-half coefficient were examined to determine the reliability. Factor structure was explored by factor analysis. Three assumptions of Rasch model-based item response theory (IRT) were assessed. Differential item functioning (DIF) was investigated concerning factors of gender, diagnosis, and treatment stage.

RESULTS

The floor or ceiling effects were detected for six domains. The reliability was found to be excellent. Furthermore, the factor structure of these six domains was validated. Our analysis confirmed that the assumptions required for IRT were met with acceptable unidimensionality, local independence, and good monotonicity. Additionally, we observed measurement equivalence, with outstanding levels of DIF across factors such as gender, diagnosis, and treatment stage.

CONCLUSION

PROMIS-Pediatric 25 is a highly reliable and valid instrument for evaluating key domains of health-related quality of life in Chinese pediatric cancer patients.

PRACTICE IMPLICATION

Nursing practice could engage the PROMIS-Pediatric 25 for accurate and quick children symptom and function assessment.

Validation of the simplified Chinese version of PROMIS Parent Proxy-25 Profile in parents of children with cancer

PURPOSE

To determine the psychometric properties of the Patient-reported Outcomes Measurement Information System Parent Proxy-25 Profile (PROMIS-25) in a sample of Chinese parents of children with cancer.

DESIGN AND METHODS

A cross-sectional sample (N = 148) of parents with children aged 5-17 years living with cancer was recruited. Each participant completed sociodemographic and clinical questionnaires and PROMIS-25. The flooring and ceiling effects were calculated. Reliability was determined by the Cronbach's alpha and split-half coefficient. Factor structure was examined by factor analysis. Model fit and graphical plots were assessed to test the assumptions of Rasch model-based item response theory (IRT). Differential item functioning (DIF) was assessed in terms of gender, age, and treatment stage.

RESULTS

PROMIS-25 demonstrated some flooring and ceiling effect, excellent reliability (Cronbach's α > 0.7 for all six domains), and the six-domain factor structure was supported. The IRT assumptions were met in terms of unidimensionality, local independence, monotonicity, and measurement equivalence with acceptable DIF in terms of gender, age, diagnosis, and treatment stage.

CONCLUSION

PROMIS-25 is a highly reliable and valid instrument for evaluating children with cancer that assesses important health-related quality of life domains of child cancer.

PRACTICE IMPLICATION

Chinese parents of children with cancer and healthcare providers could use PROMIS-25 to assess the symptoms of children.
