The nested mixed method strategy employed for data collection in the Johns' Voice project unfolded simultaneously in two phases. The first phase involved the implementation of a structured self-administered questionnaire while the second phase involved a series of in-depth conversational interviews with participants sampled in order to ensure theoretical diversity.
So as to take advantage of one of the principle strengths of the mixed methods design, data for the study was collected through a variety of different techniques, including: 1.) computer assisted self-administered questionnaires (CASQ) filled out on the World Wide Web and returned electronically; 2.) self-administered electronic paper (e-paper) versions of the questionnaire that could be obtained through the project web site or via email and returned either via email or through conventional mail; 3.) in-depth personal interviews; 4.) in-depth telephone interviews; and 5) in-depth online interviews.
