The aim of the present work was to validate the reduced version of the Morningness–Eveningness Questionnaire (MEQr) using circadian motor activity as external criterion. The MEQr was administered to a sample of 130 university students, 42 males and 88 females. All the students wore an actigraph (AMI 32K) on the non-dominant wrist for three consecutive nights and days. Acrophase was computed using cosinor analysis. The circadian motor activity of evening types presented a significant phase delay versus intermediate and morning types. Results show that the MEQr has good external validity.
