Topic guide for interview study

OpenersIf I could start by asking you how long ago you took part in the study? How did you find the experience?
Diet and exercise informationHow appropriate was the advice about diet and exercise in relation to its content and volume?
Do you feel being recruited to the study so soon after diagnosis was a good thing or would you have preferred more time?
When would have been an appropriate time?
How well were able to take in the information you were given?
Would it have been helpful to see the dietician again, or do you feel that once was enough?
Did you refer to the study information booklet? If so, how helpful was the information booklet?
Which sections of the booklet particularly helpful or unhelpful?
Do you use the booklet as a reference guide now?
Did any aspects of your diet change following looking at the information booklet?
Can you think of any better ways in which the information could have been delivered?
Health professional supportHow well supported did you feel in terms of the clinical support you received?
Did you feel you more or less well supported through being on the trial?
Do you feel being in the trial was better or worse in terms of the number of doctors/nurses you saw? Why?
Were you happy seeing the same nurse all the way through the trial or would you have preferred more variety? Did you mind no longer seeing the nurse you saw when you were diagnosed?
Do you mind not seeing these study doctors/nurses on a regular basis now?
How well balanced were the follow-up visits in terms of the health professional you saw? Would you have preferred more/less visits with a doctor/nurse etc… Or do you feel it was the right amount of time with each?
Overall, how well supported by the doctors and nurses did you feel?
Recruitment and follow-upWhere did you first hear about the trial from? Who approached you?
What appealed to you about taking part in the study in the first place? What were your reasons?
Was there anything that put you off taking part in the study?
How easy to complete and understand were the questionnaires you received?
During the trial you were required to have extra blood tests. How did you feel about having the extra bloods?
How much did you feel the follow-up visits were focused on you and how much did you feel they were focused on the trial and form filling etc… Was this appropriate or could it be weighted differently?
Would you have preferred most of the follow-up visits to have taken place face to face or over the phone?
Can you describe whether being on the study affected your confidence levels in terms of undertaking exercise?
What were your reasons for leaving the study?
Why did you choose to continue/discontinue with the 5-year follow-up as part of the study?
Motivational interviewing (intervention group only)How useful do you feel the extra support you were given by the nurse about managing your diabetes and exercising was? What were the pros and cons of talking to the nurse about this?
Would it have been helpful to have weekly phone calls from the nurse to check on how you were getting on?
Did the amount of exercise you undertook change as a result of these talks with the nurse or did it stay the same?
Did the type of exercise you undertook change or stay the same following (a) diagnosis and (b) the intervention?
How much physical activity were you carrying out before your diagnosis compared with (a) during the study and (b) now? Has your exercise levels been maintained post-study?
Did you feel more or less confident about carrying out exercise following the intervention with the nurse?
What more could have been done to encourage you to exercise?
What sort of approach might have worked for you to help you to exercise?
Some participants did not make their exercise target. Can you think how we could help them reach this target?
What methods did you use to increase your exercise levels?
Future development of studyIf there was one thing we could do to make the study easier for you to take part in what would it be?
We are planning to undertake a larger scale study similar to the one you have taken part in. What sort of things would you change about the study that might make people want to take part in it more?
Overall, what did you feel was good or bad about taking part in the study?
Do you think you would be more or less likely to participate in clinical trials following this experience?
