Methods
Population and sampling
A list of all active full-time physicians was acquired from the ministry of health (N = 320). A computerized random sample generator was used to select a sample of 175 physicians who were distributed over all 27 primary healthcare service locations around the country.
The sample size was estimated to yield at least a 90% confidence level of being within 5% of the true value, allowing for
up to 20% of a non-response rate.
From July to August 2013, physicians were approached during their allocated break time (10:30–11:00 am).
We introduced them to the research and obtained their written consent. A selfadministered confidential questionnaire in English was administered, and approximately 10 minutes were required to fill it in.
