Until now, years of experience in questionnaire design were required to estimate how long it would take a respondent, on the average, to complete a CATI questionnaire for a new survey. This presentation focuses on a new method which produces interview time estimates for questionnaires at the development stage. The method uses Blaise Audit Trail data and previous surveys. It was developed, tested and verified for accuracy on some large scale surveys.
First, audit trail data was used to determine the average time previous respondents have taken to answer specific types of questions. These would include questions that require a yes/no answer, scaled questions, "mark all that apply" questions, etc. Second, for any given questionnaire, the paths taken by population sub-groups were mapped to identify the series of questions answered by different types of respondents, and timed to determine what the longest possible interview time would be. Finally, the overall expected time it takes to complete the questionnaire is calculated using estimated proportions of the population expected to answer each question.
So far, we used paradata to accurately estimate average respondent interview completion times. We note that the method that we developed could also be used to estimate specific respondent interview completion times.

The National Population Health Survey (NPHS) is one of Statistics Canada's three major longitudinal household surveys providing an extensive coverage of the Canadian population. A panel of approximately 17,000 people are being followed up every two years for up to twenty years. The survey data are used for longitudinal analyses, although an important objective is the production of cross-sectional estimates. Each cycle panel respondents provide detailed health information (H) while, to augment the cross-sectional sample, general socio-demographic and health information (G) are collected from all members of their households. This particular collection strategy presents several observable response patterns for Panel Members after two cycles: GH-GH, GH-G*, GH-**, G*-GH, G*-G* and G*-**, where "*" denotes a missing portion of data. The article presents the methodology developed to deal with these types of longitudinal nonresponse as well as with nonresponse from a cross-sectional perspective. The use of weight adjustments for nonresponse and the creation of adjustment cells for weighting using a CHAID algorithm are discussed.

The current Survey of Employment, Payroll and Hours, conducted by the Labour Division of Statistics Canada is a major monthly survey collecting data from a large sample of business establishments. This paper describes the methodology of the survey. The description of the stratification, sample size determination and allocation procedures is brief, whereas the description of the rotation procedure is more detailed because of its complexity. Some of the possible simplifications of the design are also highlighted.
