Electronic self-report data collection is a systematic means of collecting data about health risk factors which could help to overcome screening barriers and assist in the provision of preventive health care.
The main purpose has been to gain experience in design of surface touch experiments, self-report data collection and multi-variate statistical analysis of that data, to link subjective outcomes with their physical cause.
They also are responsible for monitoring and managing off-site investigations, as well as protocol preparation, status reporting, data collection, and compilation of reports associated with the investigations.
This should significantly reduce the costs of corporate data reporting, data collection, and index construction and maintenance, as well as enhancing the signal to noise ratio in sustainability reporting.
This method of interviewer-led self-report data collection will minimise missing data.
A study of self-report data collection found the telephone to be an accurate and viable modality for information collection (Rintala and Willems 1991).
After the self-report data collection was transferred to the PC tablets, the PC tablet data were regularly sent to the coordinating center over a secure network.
Specific consideration of the processes underlying potential bias in self-report data collection remains a measurement issue: perceptual, cognitive, cultural, demographic, motivational, and affective influences on self-report data.
In addition, although we were able to recruit a diverse sample with respect to languages and care settings, the use of uniform self-report data collection in the survey (to minimise measurement bias introduced by using both staff and patient rating) may have introduced a sampling bias in that those with very poor health status could not participate.
In addition, patients were required to be well enough to participate in self-report data collection, which may bias our data against those with significant disease progression and nearing the end of life, who may have poorer QOL than patients in this sample.
