De Vaus (1991) highlights five main considerations that may be key factors in decisions about whether to use telephone or face-to-face interviews for survey work: response rates, ability to produce representative samples, effects on interview schedule design, quality of responses and implementation problems. De Vaus discussion of these five issues is outlined at the start of this article. The five issues are then applied to the experiences of researchers conducting a study on continence care. Description and discussion of pilot interviews, which explored both interview modes, are followed by a similar examination of the main study which employed telephone interviews. Ideas in this discussion are supported and challenged by reference to other publications on the subject of telephone and face-to-face interviews. The success of the decision to use telephone interviews in the main study is evaluated and recommendations are made.
