SAT0678 DEVELOPMENT AND VALIDATION OF A SELF-ADMINISTRATED QUESTIONNAIRE MEASURING ESSENTIAL KNOWLEDGE FOR PATIENTS WITH SPONDYLOARTHRITIS : THE SPONDYLOARTHRITIS ASSESSMENT KNOWLEDGE QUESTIONNAIRE(SPAKE):

Background: Patient education is recommended for patients with inflammatory arthritis to enhance self-management. Only one Knowledge Questionnaire (KQ) is available in spondyloarthritis (SpA) (ref 1) and needs to be updated according to the recent recommendations for SA and the patients’ needs (ref 2). Objectives: To develop and validate a new KQ in SpA Methods: 4 steps. Step1. Selection of knowledge considered essential for patients with SpA through Delphi rounds by a working group of rheumatologists, health professionals (HPs) and patients, leading to a list of consensual items (ref2). Step2. Two rheumatologists and a rheumatology nurse constructed the first version of the KQ, each question of the KQ referring to a selected item on the list. The formulation was then amended by the working group. A new version was elaborated during a face-to-face meeting of 3 health professionals and one patient. Step3. The KQ was submitted to ten patients for cognitive debriefing, comments were analyzed and a final version was elaborated. Step 4. Multicentric validation in 13 rheumatology departments: acceptability was measured by the rates of missing data per item, reproducibility and sensitivity to change were assessed respectively by test/retest at a 2 weeks interval (Lin’s concordance correlation coefficient) and by testing the KQ before and after patient education sessions. Results: Step1 obtained 42 items, 32 considered essential and 10 considered useful, selected respectively by more than 2/3 or more than 50% of participants to the Delphi rounds, leading to the SPAKE: a 42-items questionnaire, with a 32-items short form. The SPAKE contains 6 knowledge domains: disease knowledge (12 items), pharmacological treatment (11), non -pharmacological treatment (8), comorbidities (1), self-care for pain and fatigue (4), adaptative skills to psychosocial, professional issues and health care system (6). The validation included 130 patients, 67 (51.5%) men, mean age 43.5±12.9 years, median disease duration 8 years [3;16]. There were no missing items in the KQ. The SPAKE’s internal validity (Kuder-Richardson) was 0.85. Reproducibility (in 61 patients) was 0.81 [95% CI, 0.72; 0.89]. Sensitivity to change was measured in 55 patients. A statistically significant difference in total knowledge score was observed between the two assessment times: 29.1±6.4 vs. 34.7±5.9 (p Conclusion: This study enabled the development and the validation of the SPAKE, a knowledge questionnaire for patients with SpA, with a good acceptability, reproducibility and sensitivity to change. This KQ will be helpful to assess the process of knowledge acquisition in patient education approaches. References [1] Lubrano E, et al. Br J Rheumatol. 1998;37:437-41.2 Beauvais C, et al.
