This paper discusses in detail issues dealing with the technical aspects of designing and conducting surveys. It is intended for an audience of survey methodologists.
From January 2000, the data collection method of the Finnish Consumer Survey was changed from a Labour Force Survey panel design mode to an independent survey. All interviews are now carried out centrally from Statistics Finland's Computer Assisted Telephone Interview (CATI) Centre. There have been suggestions that the new survey mode has been influencing the respondents' answers. This paper analyses the extent of obvious changes in the results of the Finnish Consumer Survey. This is accomplished with the help of a pilot survey. Furthermore, this paper studies the interviewer's role in the data collection process. The analysis is based on cross-tabulations, chi-square tests and multinomial logit models. It shows that the new survey method produces more optimistic estimations and expectations concerning economic matters than the old method did.

This paper discusses in detail issues dealing with the technical aspects of designing and conducting surveys. It is intended for an audience of survey methodologists.
This paper describes joint research by the Office for National Statistics (ONS) and Southampton University regarding the evaluation of several different approaches to the local estimation of International Labour Office (ILO) unemployment. The need to compare estimators with different underlying assumptions has led to a focus on evaluation methods that are (partly at least) model-independent. Model-fit diagnostics that have been considered include: various residual procedures, cross-validation, predictive validation, consistency with marginals, and consistency with direct estimates within single cells. These diagnostics have been used to compare different model-based estimators with each other and with direct estimators.

This paper describes the methods used to increase the response rates of a generalist and specialist physician survey. The means of delivery (regular versus priority mail) and notification of inclusion in a draw for cash prizes were randomized using a 2 x 2 factorial design. While neither priority delivery nor notification of a cash prize sufficiently overcame whatever obstacles exist in this population, both approaches had a positive, though limited, effect on the response rate of the physicians. However, a subsequent mailing of a prepaid cash incentive (delivered by courier) was particularly effective in increasing the representation of the generalist subsample.

This paper discusses in detail issues dealing with the technical aspects of designing and conducting surveys. It is intended for an audience of survey methodologists.
To fill statistical gaps in the areas of health determinants, health status and health system usage by the Canadian population at the health region levels (sub-provincial areas or regions of interest to health authorities), Statistics Canada established a new survey called the Canadian Community Health Survey (CCHS). The CCHS consists of two separate components: a regional survey in the first year and a provincial survey in the second year. The main purpose of the regional survey, for which collection took place between September 2000 and October 2001, was to produce cross-sectional estimates for 136 health regions in Canada, based on a sample of more than 134,000 respondents. This article focuses on the various measures taken at the time of data collection to ensure a high level of quality for this large-scale survey.

Several key strategies contributed to the success of the United States' Census 2000. This paper describes the strategy for the Address Building Process that incorporated numerous address lists and updated activities. The Field Interview Process created close to 900,000 jobs that needed to be filled. Two key strategies to achieve this are also described. The Formal Quality Control Process established principles to guide the quality assurance (QA) programs. These programs are presented, as are some of the examples of their implementation. The Coverage Measurement and Correction Process was used to increase census accuracy through the use of statistical methods. The steps taken to ensure Annual Capital Expenditures (ACE) accuracy and quality are described and the preliminary estimates of the undercount are reported.

This paper discusses in detail issues dealing with the technical aspects of designing and conducting surveys. It is intended for an audience of survey methodologists.
Rather than having to rely on traditional measures of survey quality, such as response rates, the Social Survey Division of the U.K. Office for National Statistics has been looking for alternative ways to report on quality. In order to achieve this, all the processes involved throughout the lifetime of a survey, from sampling and questionnaire design through to production of the finished report, have been mapped out. Having done this, we have been able to find quality indicators for many of these processes. By using this approach, we hope to be able to appraise any changes to our processes as well as to inform our customers of the quality of the work we carry out.

The Discharge Abstract Database (DAD) is one of the key data holdings held by the Canadian Institute for Health Information (CIHI). The institute is a national, not-for-profit organization, which plays a critical role in the development of Canada's health information system. The DAD contains acute care discharge data from most Canadian hospitals. The data generated are essential for determining, for example, the number and types of procedures and the length of hospital stays. CIHI is conducting the first national data quality study of selected clinical and administrative data from the DAD. This study is evaluating and measuring the accuracy of the DAD by returning to the original data sources and comparing this information with what exists in the CIHI database, in order to identify any discrepancies and their associated reasons. This paper describes the DAD data quality study and some preliminary findings. The findings are also briefly compared with another similar study. In conclusion, the paper discusses subsequent steps for the study and how the findings from the first year are contributing to improvements in the quality of the DAD.

This paper discusses in detail issues dealing with the technical aspects of designing and conducting surveys. It is intended for an audience of survey methodologists.
The accurate recording of patients' Indegenous status in hospital separations data is critical to analyses of health service use by Aboriginal and Torres Strait Islander Australians, who have relatively poor health. However, the accuracy of these data is now well understood. In 1998, a methodology for assessing the data accuracy was piloted in 11 public hospitals. Data were collected for 8,267 patients using a personal interview, and compared with the corresponding, routinely collected data. Among the 11 hospitals, the proportion of patients correctly recorded as Indigenous ranged from 55 % to 100 %. Overall, hospitals with high proportions of Indigenous persons in their catchment areas reported more accurate data. The methodology has since been used to assess data quality in hospitals in two Australian states and to promote best practice data collection.

The upcoming 2002 U.S. Economic Census will give businesses the option of submitting their data on paper or by electronic media. If reporting electronically, they may report via Windows-based Computerized Self-Administered Questionnaires (CSAQs). The U.S. Census Bureau will offer electronic reporting for over 650 different forms to all respondents. The U.S. Census Bureau has assembled a cross-divisional team to develop an electronic forms style guide, outlining the design standards to use in electronic form creation and ensuring that the quality of the form designs will be consistent throughout.
The purpose of a style guide is to foster consistency among the various analysts who may be working on different pieces of a software development project (in this case, a CSAQ). The team determined that the style guide should include standards for layout and screen design, navigation, graphics, edit capabilities, additional help, feedback, audit trails, and accessibility for disabled users.
Members of the team signed up to develop various sections of the style guide. The team met weekly to discuss and review the sections. Members of the team also conducted usability tests on edits, and subject-matter employees provided recommendations to upper management. Team members conducted usability testing on prototype forms with actual respondents. The team called in subject-matter experts as necessary to assist in making decisions about particular forms where the constraints of the electronic medium required changes to the paper form.
The style guide will become the standard for all CSAQs for the 2002 Economic Census, which will ensure consistency across the survey programs.

This paper discusses the Office for National Statistics' (ONS) approach to developing systematic quality measurements and reporting methods. It is presented against the background of European developments and the growing demand for quality measurement. Measuring the quality of statistics presents considerable practical and methodological challenges. The paper describes the main building blocks to be used for the new quality measure program, and includes specific examples. Working with other national statistical institutions; and developing an enhanced measurement framework, output measurements, and reporting procedures, are all vital ingredients in achieving recognition of the ONS as a quality organization.
