The course is of 3 ECTS and is organised by Prof. Ulf Emanuelson, Swedish University of Agricultural Sciences.
Questionnaires have become a major source for data in epidemiological studies. One reason is the increased interest in qualitative and sociological methods to explain the spread of diseases. Another reason is that it has become increasingly easy to construct and distribute questionnaires and carry out follow-up to improve compliance. The competence in designing such studies has not increased in the same way. This has serious impacts on the internal and external validity of these studies. Problems arise because questions are not properly framed and because response rates are low and not representative of the target population, but also because questionnaires are very prone for having missing information which makes multivariable analyses very difficult. This course will tackle two key issues related to the effective use of questionnaires, namely all the key elements of questionnaire design and management as well as methods for evaluating and dealing with item nonresponse with an emphasis on the use of multiple imputation of missing observations.
