The nine-volume Survey Kit is designed to help readers prepare and conduct surveys and become better users of survey results. All the books in the series contain instructional objectives, exercises and answers, examples of surveys in use, illustrations of survey questions, guidelines for action, checklists of "dos and don'ts," and annotated references. This volume, fifth in the series, guides the reader in selecting and using appropriate survey designs. The following specific objectives are met in this volume: (1) describe the major features of high-quality survey systems; (2) identify the questions that structure survey designs; (3) distinguish between experimental and observational designs; (4) explain the characteristics, benefits, and concerns of designs that include concurrent controls with and without random assignment, self- and historical controls, and cross-sectional, cohort, and case- control designs; (5) identify the risks to internal validity; and (7) identify the risks to a design's external validity. The chapters are titled "Useful Surveys" and "Classification of Designs for Surveys." An annotated list of five additional readings is provided. (Contains 18 examples and 5 figures.) (SLD)
