The telephone survey is now the dominant survey technique. When the first edition of this volume was published, many researchers were making the transition from mail to face-to-face interviewing to telephone surveys. However, much material from the first edition remains applicable today. Additional material in this second edition includes a summary of changes in telephone surveys that have occurred during the last five years. The author also analyzes the comparative advantages and disadvantages of mail, face-to-face and telephone surveys, and discusses the legal and ethical dilemmas raised by technological and methodological developments in telephone survey research.
