Using a National Register as a Sampling Frame from the Perspective of an Early Career Researcher

Background: Selection of a sampling frame is a key component of conducting survey-based research. This article discusses the use of a national register, the Dental Register, as a sampling frame from the perspective of an early career researcher. Methods: While conducting a survey-based study of a nationally representative sample of general dentists in Ireland, I documented the difficulties I encountered while using a national register. As a research assistant and novice researcher, I recorded the advantages and disadvantages I discovered over the course of the project and its impact on the study. Conclusion: While using a national register has advantages such as a readily available sample of the target population, there are also inherent disadvantages depending on the manner in which records are recorded. Knowledge Transfer Statement: This article can be used as an informative guide to researchers in selecting a sampling frame, with particular emphasis on the use of a national register in selecting a nationally representative sample of dentists.
