Operations - Verbal interview - Assessment Centre
DescriptionThis category contains data obtained through a verbal interview by a trained nurse on major operations. It includes data on type of operation (grouped by body region, and presented in a tree structure), the number of operations, and date of each one.
The interviewer was made aware, via a pop-up box on their computer screen, if the participant had answered in the touchscreen that they had a history of a major operation, and was prompted to ask "Could you now tell me what the operation was?" For example, if a woman had indicated in the touchscreen that they had had a hysterectomy or bilateral oopherectomy, this would already have been selected in the operation tree. If during the interview it appeared these had been incorrectly selected, the interviewer could alter the responses. If the participant stated in the touchscreen they had no history of major operations (or were not sure), this question was asked again and confirmed by the interviewer.
Operations that could not be coded at the time of the interview were entered as free text, and subsequently coded wherever possible.
