The quality driven approach
• Response burden is mainly a problem as long as it affects
the response quality
• It is the respondents’ response burdens that matters
• Perceived response burden is a more relevant variable than
completion time
• The response burden may be affected by external
conditions or personal characteristics of the respondents as
well as by the survey design.
• Perceived response burden questions should identify why
questionnaires are burdensome

Sources of perceived response burden
•
Survey Design Factors
– Characteristics of 6 web questionnaires directed to different industries
– (The time it took to fill in the questionnaire)
•
External conditions
– Size: The number of employees
– Information sources: Documentation problems that made the information
collection time consuming
– Division of labour: The number of persons who took part in the response
process
•
Personal Characteristics
– Availability: How easy or difficult it was to set aside time for the
questionnaire
– Motivation: How useful for the business and society the respondent felt that
statistics produced from the data were
– Competence: If he/she was a first time or experienced respondent

The effect of survey design, external conditions and
personal characteristics on PRB
• Calculations and mismatch between questions and available
•
•
•
•
•
information are general problems in business surveys
Sufficient time available for the questionnaire is essential for
the perceived response burden.
The number of questions was probably the most important
difference between questionnaires
Poor layout and usability problems were often mentioned by
those who felt that the questionnaire was very burdensome
The quality of documentation systems is probably the most
important difference between industries
The perception of uselessness goes together with perceived
response burden

The impact of perceived response burden on data
collection and data quality
• Generally in business surveys..
– the data collection time is very long and
– the number of questionnaires that are corrected is very high
• When there is a pronounced difference in perceived
response burden between questionnaires, there also seems
to be a difference in…
– How quickly the data are received
– The number of questionnaires that need to be corrected
• Problems with collecting the information asked for may also
have an effect on these quality indicators

(The perceived response burden of web versus
paper questionnaires)
• When the Manufacturing Industry Survey changed from
paper to web…
– The perceived response burden apparently went down
– While the number of problems reported by those who felt the
questionnaire burdensome seemed to go up
A quote for reflection: “It takes 100 men to do as much
harm as a computer can make within 1/100 of a second”
