title: [Creating a specific diagnostic and quality-of-life questionnaire for patients with ocular surface disease].
abstract: BACKGROUND
  Ocular surface diseases (OSD) affect about 15% of the population over 65 years of age. Nevertheless, OSD knowledge in the scientific community remains poor, and the healthcare system does not adequately recognize this disorder. However, many patients with OSD suffering from chronic pain experience substantial alteration in their quality of life (QoL).
  
  
  OBJECTIVE
  Our work aimed at developing a patient self-evaluation questionnaire specific to OSD. This questionnaire could thus become a useful diagnostic tool that ophthalmologists could employ in daily practice in order to better understand patients'complaints and thereby correctly treat their disease. It also may serve as an evaluation tool in medical research. This article describes the phases of item generation, validation by experts, and identification of dimensions in the QoL section.
  
  
  METHODS
  The questionnaire was developed in French by a group of experts including clinicians and methodologists. It comprised two parts: one on diagnostic aid, and the other on subjective perception of the disease (symptoms, perception of treatment, quality of life). The questionnaire was tested on five patients. It was then modified according to the patients' suggestions and tested again on 20 patients. After a second review by the scientific committee, a pilot questionnaire suitable for systematic use in quantitative studies was prepared. A cross-sectional observational study then identified the statistical dimensions of the QoL section, which led to a reduction in the total number of items.
  
  
  RESULTS
  The resulting operational version of the questionnaire included four sections
  
  
  CONCLUSIONS
  The next study will test the reproducibility of the operational version of the OSD questionnaire obtained after the item reduction phase.
