Cultural adaptation and validation of the Quality of Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO) in a Mexican population.

Measuring quality of life (QOL) is important, but to date, questionnaires to measure QOL in Mexican patients with osteoporosis (OP) have not been validated. A study was carried out to culturally adapt and validate the Quality of Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO) in a Mexican population. Interviews were performed with 160 women, 80 patients with at least one vertebral fracture, and 80 patients with OP as determined by the World Health Organization criteria.
