Abstract

Surveys of health professionals typically have low response rates, which have decreased in recent years. We report on the methods used, participation rates, and study time for 11 national questionnaire studies of dentists conducted from 2014–2022. Participation rates decreased (87%–25%). Concurrent with this decrease was a decrease in the intensity with which the practitioners were recruited. Participation rates were higher when postal mail invitation and paper options were used (84% vs. 58%, p < .001). Completion rates were nearly twice as high in studies that recruited in waves than those that did not (61% vs. 35%, p = .003). Study time varied from 2.6 to 28.4 weeks. Study time was longest when postal mail and completion on paper were used (26.0 vs. 11.3 weeks, p = .01). Among studies using only online methods, study time was longer when invitations were staggered than when all invitations went out in one bolus (means 12.0 and 5.2, p = .04). Study time was positively correlated with participation rates (Spearman r = .80, p = .005). General dentists participated at an average of 12% higher rates than specialists. Recruitment methodology, such as recruiting in waves or stages, should be considered when designing surveys.

  • Recruiting practitioners is a persistent challenge for DPBRNs.

    “It is clear that recruiting practitioners is a persistent challenge for DPBRNs. Without them, no research project can succeed [26,27].”

    From Private Dental Practitioners' Experience in a Dental Practice-Based Research Network: A Qualitative Evaluation (2026) · cites this paper as [27]

    The Discussion reports that participation among practitioners in one dental practice-based research network declined over eight years, supporting concern about recruiting them for surveys. The Methods clarify that these practitioners were already network members, and the Results say recruitment goals were met for every study. The paper therefore does not establish that recruiting practitioners into DPBRNs is a persistent challenge across networks. (LLM, conf=0.82)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
