Cervical Screening in Iranian Migrants

Abstract

The cervical screening status of small and geographically diverse migrant communities is particularly difficult to assess. Usual approaches to migrant research such as telephone surveys using ethnically identifiable names or cluster sampling might not be feasible. Snowball sampling, although sometimes criticised for problems of inference with non-probability samples, might be the only cost-effective and viable alternative. Snowball sampling is the method of choice by sociologists studying networks and group interactions and has been shown to yield similar estimates of attitudes and demographic characteristics as probability sampling methods (Rumbaut, Chavez, Moser, Pickwell, & Wishik, 1988; Welch, 1975).
