Online Surveys: Effect of Research Design on Rates of Invalid Participation and Data Credibility
Bibliographic record
Abstract
Designing online research often involves a trade-off between procedures that maximize administration efficiency and those that encourage valid and considerate participation. This article reports on three different online research design conditions (n = 413), differing in participant screening, incentive, and anonymity, that were used in a separate study on cognition in smoking cessation. High rates of invalid participation were observed in a condition in which participants participated anonymously, received a $20 incentive, and were screened for eligibility online. In addition, this condition produced significantly different data (variance, covariance, and central tendency) than the other two conditions, which involved less incentive or personal eligibility screening without participant anonymity. Removal of apparent “invalid” participants on the basis of a data screening protocol corrected some, but not all, of these differences. Results indicate that online designs offering monetary incentives should implement procedures to enhance data integrity even at the cost of increased participation barriers.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
