The interview questions will cover the participant's knowledge of sedentary behaviour, their views on regular breaks in sedentary behaviour, the use of technology in promoting breaks in sedentary behaviour and their experiences of using technology to increase their breaks in sedentary behaviour to improve their glycaemic control. All interviews will be tape recorded with the participants' permission and, due to the flexible nature of the process and individual responses of the participants, it is anticipated that each interview will last 1 hour.
