Is the patient-perceived impact of psoriatic arthritis a global concept? An international study in 13 Arab countries (TACTIC study)

AbstractThe Psoriatic Arthritis Impact of Disease (PsAID-12) questionnaire, a recommended measure of patient-reported impact for psoriatic arthritis (PsA), was initially developed in Europe and may lack universal validity. Recognizing the need for a culturally appropriate tool for Arab patients, this study aimed to TranslAte, CulTurally adapt, and validate the PsAID in ArabIC (TACTIC). The PsAID-12 was translated into Arabic using a rigorous process of double translation, back-translation, and cognitive debriefing. The Arabic version was then validated through a study conducted in 13 Arab countries in 2022. Participants were consecutive literate adult patients diagnosed with PsA and fulfilling the CASPAR criteria. Collected data included PsAID-12, disease activity, and legacy patient-reported outcomes. Psychometric properties, such as internal consistency, construct validity, and test –retest reliability, were examined. Factors associated with high PsAID-12 total scores (>  4) were explored using multivariable binary logistic regression. A culturally adapted Arabic PsAID-12 questionnaire was achieved with minor rephrasing. The validation study included 554 patients from 13 countries (mean age 45 years, 59% females), with a mean PsAID score of 3.86 (SD 2.33). The Ar abic PsAID-12 demonstrated excellent internal consistency (Cronbach’sα = 0.95), and correlations with other measures ranged from 0.63 to 0.78. Test–retest reliability (N = 138 patients) was sub...
