Stage 3: Testing the face validity of candidate items
Stage 3 involved semi-structured face to face or telephone interviews with patients (acute, long-term conditions, and mental health service users), social care users, carers and the general public to test the face validity of identified items and their response options. This was undertaken in England as well as in five other countries (Argentina, Australia, China, Germany, USA) by international collaborators.
The findings from this stage were used to reduce the number of items that were taken forward to validation using a large survey.
