Outline

• A growing focus on how to improve response rates, minimize response bias and monitor fieldwork costs during the fieldwork period

• Combination of easily retrieved administrative data and process data make continuous monitoring of survey variable of interest possible

• The task is to maximize the result, given certain constraints as time or costs

SIV – A system for managing multi mode data collection

• Co-ordinates CATI, CAPI, CAWI and Paper Questionnaires

• Master Management system

• Updates, reports and graphs

• Quick and continuous re-scheduling of actions

Examples of Administrative Data

• Mode(s)

• Data collection period and dates of actions

• Budget

• Number of Interviewers

• Interviewer characteristics

Examples of Process Data

• Response rate

• Composition of nonresponse

– Refusal rate

– Non-contact rate

• Telephone coverage

• Workload

• Cost

Data we would like to monitor

During the data collection process, we would like to monitor the composition of…..

• Process data

• Auxiliary data

• Target variables

Page 9: Management Tools for Enhancing the Composition of Survey Response

Examples of Quality Indicators

• Response rate

• Non-response rate

• Response bias

• Response burden

• Revisions

• Errors

Management Tools - Challenges

• Get used to communicate through data displays

• High skilled project managers

• Demand of quick re-sceduling procedures

Page 17: Management Tools for Enhancing the Composition of Survey Response

17

Management Tool - Limitations

• May draw attention away from serious measurement problems

• May indicate more than one issue of concern

• May add new bias

Page 18: Management Tools for Enhancing the Composition of Survey Response

Further work

• Development of SIV

• Experiences from real-time data collections

• Development of more sophisticated management tools
