"An expert in questionnaire-based research, Dornyei has produced an informative, fully updated, very accessible, and highly practical treatment of questionnaires in second language research. Through its balanced presentation of theoretical principles and sage advice as well as concrete examples of questionnaire design, administration, and analysis, the book offers applied linguists a wonderful resource with wide applicability."

-Patricia A. Duff, University of British Columbia, Canada

"This is an outstanding ‘how to’ resource book for L2 researchers and their students. It will be useful to all who use questionnaires, whether regularly or only on occasion. It is written in an exceptionally clear and accessible style. This Second Edition contains welcome new material—a step-by-step examination of a case study, detailed discussion of how to handle translation, and information on internet-based questionnaires. Altogether, very highly recommended!"
