Dimensionando los hechos: la encuesta (II)

The present study pays special attention to the questionnaire design, i.e., to the selection of items to be included, the formulation of questions, and the diverse answer formats (open, Thurstone, Osgood, Likert, etc.). An essential element of questionnaires is their validation, as a measurement tool, especially validation of comprehension, reliability, validity and cultural adaptation.
