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.
