"Picture this"- Patients' Drawings of Non-Muscle Invasive Bladder Cancer: A Novel Method to Help Understand How Patients Perceive Their Condition.

Background: There is a paucity of data regarding patient experiences of living with non-muscle-invasive bladder cancer (NMIBC).

Objectives: To investigate patients' beliefs about NMIBC utilising both a well-established verbal/linguistic method, the Brief Illness Perception Questionnaire (B-IPQ) in addition to a novel visual/perceptual method, that is, asking patients to draw their bladder as it is now and as they perceive it will be in the future.

Methods: Cross-sectional study of patients with NMIBC.
