Summary
Computer-assisted data entry using Teleform for population surveys achieved high accuracy. While systematic processes ensure reliable data transfer, administrative and technical challenges require attention for optimal survey data management.
Area of Science:
- Health Services Research
- Medical Informatics
- Survey Methodology
Background:
- Computer-assisted data entry for population surveys is an emerging field.
- Previous reports on such procedures are limited.
- Self-completion surveys present unique data entry challenges.
Purpose of the Study:
- To evaluate the effectiveness and accuracy of Teleform software for computer-assisted data entry in a large-scale population survey.
- To identify potential administrative and technical issues associated with implementing this technology.
Main Methods:
- A questionnaire was distributed to 8995 registrants aged 50+ in North Staffordshire, UK.
- Teleform software was utilized for scanning and data entry of returned questionnaires.
- Scanned questionnaires underwent manual checking and correction to ensure data accuracy.
Main Results:
- The survey achieved a 77% response rate, with 98% of returned questionnaires being scannable.
- A low data entry error rate of 0.041% per questionnaire item was observed after checks.
- Systematic processes demonstrated Teleform's capability for accurate survey data transfer.
Conclusions:
- Teleform can facilitate accurate data transfer in population surveys.
- Addressing administrative and technical issues is crucial for successful implementation.
- This study provides a benchmark for computer-assisted data entry in health surveys.
