Abstract
Development of a spanish adaptation of the Infant Behavior Questionnaire for the measurement of tem perament in infancy. The aim of this work was to adapt the Infant Behavior Questionnaire (IBQ; Rothbart, 1981) for the measurement of infant temperament to the Spanish population. 60 families participated in a longitudinal study. The questionniare was translated into Spanish and then filled out by the mothers when their children were 3, 6, and 9 months old. The different psychometric coefficients provided by the temperament scales appeared to be similar to those reported by the author of the original questionnaire. Also, the relationships exhibited by the scales can be supported by a current framework of temperament in infancy.
