Abstract Background Therapeutic advances in lung cancer have turned attention toward patient‐reported outcome measures (PROMs) as important clinical outcomes. The Functional Assessment of Cancer Therapy‐Lung (FACT‐L) is a common endpoint in lung cancer trials. This study calculated FACT‐L reference values for the United States (US) general population. Methods Adults from the US general population (N = 2001) were surveyed between September 2020 and November 2020. Surveys contained 126 questions, including the FACT‐L [36 items; FACT‐G and four subscales (Physical Well‐Being [PWB], Social Well‐Being [SWB], Emotional Well‐Being [EWB], and Functional Well‐Being [FWB]) and the Lung Cancer Subscale (LCS), and a Trial Outcome Index (TOI)]. Reference values for each FACT‐L scale were calculated with means for the total sample and separately for participants with: no comorbidities, COVID‐19 as only comorbidity, no COVID‐19. Results In the total sample, the reference scores were as follows: PWB = 23.1; SWB = 16.8; EWB = 18.5; FWB = 17.6; FACT‐G = 76.0; LCS = 23.0, TOI = 63.7, and FACT‐L Total = 99.0. Scores were lower for those reporting a prior diagnosis of COVID‐19, especially for SWB (15.7) and FWB (15.3). SWB scores were lower than previous references values. Conclusions These data provide US general adult population reference value set for FACT‐L. While some of the subscale results were lower than those found in the reference data for other PROMs, these data were obtained in a more contemporaneous time frame juxtaposed with the COVID‐19 pandemic and may represent a new peri‐pandemic norm. Thus, these reference values will be useful for future clinical research.
