Testing Skype as an interview method in epidemiologic research: response and feasibility.

INTRODUCTION: Despite its popularity, Skype has not been tested as a tool for epidemiologic research. We examined its feasibility in Germany.

METHODS: A population-based sample of young adults was randomly invited to a Skype (n = 150) or a phone interview (n = 150). Response and duration of interviews were analysed to evaluate the feasibility of Skype interviews.

RESULTS: Response was low and, with 10 % (95 % CI 5-15 %), even worse among Skype candidates, compared to 22 % (15-28 %) in the phone group. A third of the Skype group asked for being interviewed by phone. Median duration was 34.0 minutes for Skype interviews and 37.0 minutes for phone interviews.

CONCLUSIONS: Skype is not yet a feasible tool for data collection in Germany.
