Psychometric evaluation of the PROMIS social function short forms in Chinese patients with breast cancer

Abstract

Background The diagnosis of breast cancer and the subsequent treatment undermine patients’ participation in social activities. This study aimed to carry out a cross-cultural adaption and analysis of the construct validity and reliability of the Chinese version of the PROMIS social function short forms in patients with breast cancer. Methods This study utilized a cross-sectional research design, and was registered in the Chinese Clinical Trial Registry (ChiCTR2000035439). After a standardized cross-cultural adaption process, a psychometric evaluation was performed of the Chinese version of the PROMIS social function short forms. Using convenience sampling, eligible patients with breast cancer from tertiary hospitals in China were enrolled from January 2019 to July 2020. Participants completed the sociodemographic information questionnaire, the PROMIS social function short forms, the Functional Assessment of Cancer Therapy-Breast, the PROMIS emotional support short form and the PROMIS anxiety short form. Results Data were collected from a sample of 633 patients whose mean age was 48.1 years. The measures showed an absence of floor and ceiling effects. Regarding construct validity, the results of confirmatory factor analysis supported the original two-factor structure of the PROMIS social function short forms. In addition, the measures were found to have acceptable known-group validity, measurement invariance, and convergent and discriminate validity. Regarding reliability, the Cronbach’s α was high for all items (> 0.70). Conclusion The Chinese version of the PROMIS social function short forms was demonstrated to be a valid and reliable measure for the assessment of social function in Chinese patients with breast cancer. Additional psychometric evaluation is needed to draw firm conclusions.

Hungarian PROMIS-29+2: psychometric properties and population reference values

“…A major advantage of the three PROMIS generic profile measures is that they are able to produce comparable results to the complete item banks [5]. Although originating from the US, the item banks and the profile measures have been translated to several languages and have increasingly been used in European and Asian countries [8][9][10][11][12]. As standardised HRQoL measures are required to maintain their psychometric performance in different languages, the robustness of measurement properties needs to be confirmed for all language versions.…”
