ROMERO-HERNANDEZ, Astrid X.; GALINDO-VAZQUEZ, Óscar; PENEDO, Frank J. y BARGALLO-ROCHA, Juan E.. Psychometric properties of the PROMIS® v2.0 Cognitive Function Short Form (SF-8) in a Mexican cancer population. Gac. mex. oncol. [online]. 2022, vol.21, n.4, pp.119-128. Epub 05-Dic-2022.

Background:
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:
200 people with an average age of 46.34, mostly in stages II and III, in active treatment or follow-up.
Design:
Instrumental, non-experimental cross-sectional. Instruments F-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).
Conclusions:
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.
