Popis: BackgroundPsoriatic arthritis (PsA) is a chronic inflammatory disease of widely varying presentation, which determines functional and psychological impairment, with a high negative impact on patients’ quality of life. Therefore, knowing the patient’s perception of their health status is of fundamental importance for understanding the real impact of PsA. In recent years, a PsAID (Psoriatic Arthritis Impact of Disease) questionnaire has been developed for PsA EULAR, consisting of 9 or 12 questions related to the severity of pain, anxiety, fatigue, disability, sleep disorders, and social activity.ObjectivesTo study, in a real-life setting, the construct and convergent validity, the reliability, and the interpretability of the Russian version PsAID-12 in patients with PsA.Methods187 (M/F=97 (50.2%)/90(48.8%) PsA pts fulfilling the CASPAR criteria were included. Mean age 45.6±11.7 years (yrs), DAPSA 21.05±21.03, median (Me) PsA duration 88 [16;421] mo. All pts underwent standard clinical examinations and PROs (EQ-5D, PsAID12). Reliability was assessed by Cronbach’s alpha coefficient and by the intraclass correlation coefficient (ICC) for each of the 12 scales. The construct validity was evaluated by exploratory factorial analysis and also by Spearman correlation with EQ-5D and measures of disease activity evaluation.ResultsThe reliability of ICC (alpha-Cronbach = 0.8-0.9) and test-retest (ICC 95%CI 0.85-0.96) were good. Construct validity: Factor analysis revealed a 2-factor result defined as the PsAID-12: Phisical health score and Emotional health score. A strong correlation was also found for each of the 12 scales with the questionnaire EQ-5D was strong correlation (r= -0.52 to -0.78, pTable 1.Convergent validity PsAID-12 with clinical parameters (r)ScalesTJC 68SJC 66DAPSAVAS global assessmentsVAS global painBASDAIPain0,60,680,710,720,750,78Fatigue0,590,620,680,710,680,75Skin problems0,350,360,410,470,370,46Work and/or leisure activities0,570,620,680,750,710,67Functional capacity0,610,640,720,790,710,80Discomfort0,610,650,710,770,700,76Sleep disturbance0,440,500,540,550,600,61Coping0,590,630,670,660,650,76Anxiety, fear and uncertainty0,460,480,520,520,510,64Embarrasment0,470,490,510,480,410,52Social participant0,540,570,620,640,620,66Depression0,430,430,490,570,540,47ConclusionThe russian version of PsAID-12 has been shown to be a reliable and valid measure of the impact of the disease in patients with psoriatic arthritis.Disclosure of InterestsNone declared
