This paper is on the role that the phone plays in a mixed-methods empirical research. In the current sociological literature, the phone is a methodological object associated with quantitative fieldwork, while little is said on the phone as a tool for qualitative research. We reflect here on a case study on the use of parental leaves by fathers in Spain, which included the phone as the only communication tool between researchers and subjects. We collect out own experience as interviewers in the qualitative phase of the research project, and interviewed surveyors working in the field. We analyze the discursive data following grounded theory principles and compare the use of both techniques in the data gathering process, including sampling and design. Thus, we consider interviewing and surveying as mediated communication situations. Our findings show that the value of the phone as a tool for research is a matter of adequacy to a given methodology, rather than an issue of validity, reliability, or credibility. © 2013 Springer Science+Business Media Dordrecht.
