Translation, cross-cultural adaptation, and validation of a Latin American Spanish version of the ID Migraine screening test.

Objective: To translate, culturally adapt, and validate a version of the ID Migraine into Latin American Spanish.

Background: Although still considered a common diagnosis, half of the patients with migraine in Latin America experience diagnostic delay. The ID Migraine is a test developed in 2003 as a valuable tool for the early diagnosis of migraine at the primary care level; however, there is no validated Spanish or culturally adapted version for the Spanish-speaking population.
