The Canadian Birth Place Study: Development, Validation and Administration of a Questionnaire for Multi-disciplinary Maternity Care Providers
Bibliographic record
Abstract
The debate between professional groups in Canada about the advisability of planned home birth continues. The Canadian Birth Place Study examines Canadian registered midwives', family physicians', and obstetricians' experiences with and attitudes towards planned home birth, as well as factors associated with in those attitudes. Evidence based strategies were applied to the development, validity testing, and implementation of a cross-sectional questionnaire to a multi-disciplinary sample of maternity care providers.The survey questions and attitude scale items were adapted from a previously validated questionnaire and reviewed by two discipline-specific expert panels. Experts provided qualitative comments and rated each socio-demographic and attitude item on three 4-point Likert-type scales to evaluate importance, clarity, and relevance. Aggregated scores (content validity indices) demonstrated strong content validity of items. The questionnaire construction and administration plan incorporated best practices for increasing response rates among healthcare providers, as well as participation from multiple perspectives on a controversial topic across study populations.

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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
