Aim This study aimed to culturally adapt and psychometrically validate the PROMIS Social Relationships Short Forms (PROMIS‐SR) among Chinese patients with breast cancer. Design A cross‐sectional study. Method The PROMIS‐SR was translated into simplified Chinese by strictly adhering to the Functional Assessment of Chronic Illness Therapy translation method and was subsequently tested among patients with breast cancer ( N = 965). Eligible patients filled out the demographic information questionnaire, the PROMIS‐SR, and the Functional Assessment of Cancer Therapy‐Breast. Results Confirmatory factor analysis (CFA) provided support for the original structure of the PROMIS‐SR. All instruments reported strong known‐group, cross‐cultural and convergent validity, as hypothesized. Correlation coefficients ranged from 0.67 to 0.85, and Cronbach's α of all items were high (0.90–0.94).
