Despite questionnaires being one of the principal research tools in social research, there remains a glaring lack of material on this method. Following on the success of his first set, Martin Bulmer once again tackles this lack by bringing together a wealth of material - both the classics and difficult-to-find key material - to create a second invaluble resource on questionnaires.

Volume 1 reviews the place of questionnaires in the social world. It examines pre-testing questions, types of question, question order, mode effects and further questions the implications of attitudes and behaviour for questions.

Volume Two addresses methodological issues and approaches. Topics considered include question wording, response effects, the effect of respondent and interviewer characteristics on outcome and randomised response.

Volume Three presents an issue only lightly examined in the first set: Computer Assisted Interviewing [CAI]. The history and varieties of CAI are thoroughly explored and response bias, mode interactions, coding, email questionnaires and web questionnaires examined.

Volume Four is a conclusive treatment of the varieties and problems of research involving questionnaires. It brings together key material on using projective tests, vignettes, constructing questions for qualitative interviewing, the role of questions in the focus group, attitude measurement and measurement problems in general.

With entirely new material and a shift in emphasis, Questionnaires 2 is sure to make the SAGE Benchmarks coverage of this key method even more complete.
