To determine feasibility, reliability and validity of the shortened version of the Quality of Life in Epilepsy Inventory-10 (QOLIE-10) in a population of refractory epilepsy adult patients in the Colombian Caribbean. Data were collected from 63 adult refractory epilepsy patients. The ten items of QOLIE-10 were derived from the Spanish version of QOLIE-89. We assess feasibility, validity, factorial analysis with communalities, reliability through internal consistency and sensitivity to change. Clinical and demographic features were determined; quality of life was established through frequencies. Construct validity: through factor analysis communalities there were no items considered irrelevant and were grouped into one single dimension. Kaiser-Meyer-Olkin: 0.891. Bartlett's test of sphericity: p < 0.001. Average intraclass correlation coefficient 0.843. The internal consistency reliability coefficient (Cronbach's alpha) was 0.98. The QOLIE-10 questionnaire for the assessment of health-related quality of life was validated in Spanish for adult patients with refractory epilepsy with excellent validity, reliability parameters and easy, quick filling. The QOLIE-10 questionnaire is a valid and reliable tool for use in adult patients with refractory epilepsy in Colombia. Health professionals are encouraged to use this questionnaire to routinely examine the influences of the disease process in epilepsy patients.
