Aim: To validate the French version of the 37-item Functional Assessment of Cancer Therapy-Cognitive Function, including the four items related to multitasking, previously excluded from the scoring algorithm. Materials & methods: A cross-sectional study was carried out among 261 cancer patients. Validity was confirmed by factor analyses using the principal component analysis technique. Results: Construct validity was demonstrated, and items loaded on subscales with adequate sample adequacy to factor analyses outcomes. Better cognitive functioning was noted with age and in working patients, whereas lower functioning was observed in metastatic patients. Conclusion: The 37-item French tool is valid and reliable; questions related to multitasking could be included in the score.

A study was carried out among 261 cancer patients to evaluate their cognitive function using the French version of a 37-item validated scale. Our results demonstrated that the tool is valid and reliable. Better cognition was noted in older patients compared with younger ones, and lower cognitive functioning was observed in patients with metastatic cancer. This newly validated tool could help clinicians assess cognition in their routine practice.
