Abstract

Objective: To test a possible day-of-the-week effect on doctors' response rate to a postal questionnaire.

Design: Dispatch of postal questionnaire randomized to Thursday or Saturday.

Setting: A nationwide survey on doctors' attitudes.

Subjects: 200 general practitioners and 260 practising specialists/consultants.

Main outcome measures: Response rate and Kaplan-Meier survival curve for no-response.

Results: The probability of response was not influenced by receiving the questionnaire just before or just after a week-end.

Conclusion: Response rates in postal surveys sent to doctors cannot be improved by their receiving the questionnaire just before a week-end.
