People with cancer present subjective cognitive complaints during or after cancer treatment that can affect their quality of life. The evaluation of these through self-report instruments allows their referral to neuropsychological care. Objective: To determine the psychometric properties of PROMIS ® v2.0 Cognitive Function Brief Form (SF-8) in a sample of Mexican patients with cancer. Method: A total of 200 people with an average age of 46.34, mostly in Stages II and III, in active treatment or

Instruments: SF-8 and effects on quality of life subscale of the Cancer Therapy Functional Assessment Instrument-Cognitive Function. Analysis: Factor structure, confirmatory factor analysis, and concurrent validity test. Results: An unifactorial model was obtained that explained 73.27% of the variance, internal consistency index α = 0.99, with high factorial loads (0.69, -0.92), which was corroborated with the confirmatory analysis, with excellent adjustment indexes. The correlation between instruments was r: 0.69 (p < 0.01). Conclusion: The Mexican version of the SF-8 is a valid and reliable instrument for the measurement of subjective cognitive complaints, so its use in the clinical and research field is recommended.
