Postal surveys are becoming an increasingly popular method of conducting research in Malaysia. However, the response rates from these surveys have not been well studied. All postal survey published in the Medical Journal of Malaysia between 1991-2000 were therefore reviewed to provide an overview of the response rates that may be expected, and to assess if this is a valid method of conducting research here. The response rates of postal surveys ranged from 30 - 87.5%. Seven of 13 postal surveys (54%) had a response rate of less than 50% and only 2 of 13 (15.4%) had a response rate of more than 70%, raising doubts on the use of postal surveys as a research tool.
