Cross‐cultural adaptation of the Brazilian–Portuguese version of the chronic urticaria quality‐of‐life questionnaire – CU‐Q₂oL

Abstract

The CU-Q(2)oL Brazilian portuguese version was easily filled out, well accepted by the patients, demonstrated an acceptable validity and reliability and might be used to evaluate treatment outcomes and in clinical research.

Disease Activity Only Moderately Correlates with Quality of Life Impairment in Patients with Chronic Spontaneous Urticaria

“…Notably, this correlation was higher as compared to those of the DLQI and the UAS, again suggesting that the DLQI is not ideally suited for CSU patients. These findings are in line with earlier investigations that also found only moderate correlations in the German (r = 0.39), Turkish (r = 0.48) and Brazilian (r = 0.39) populations [15,16,26]. Interestingly, we could identify patients with relatively low UAS but high CU-Q 2 oL scores.…”

“…The results of the EFA of the validation phase revealed a six-dimensional structure of the Greek CU-Q 2 oL, which is in accordance with the original Italian, German and Polish versions [11,13,14], but different from the three-dimensional-structure of the Portuguese-Brazilian version [16]. The levels of internal consistency were satisfactory to excellent for all six identified dimensions (‘Functioning', ‘Sleep', ‘Embarrassment', ‘Eating/limits', ‘Mental status' and ‘Symptoms').…”

“…These 23 questions are grouped in scales, which are different in the original Italian [11] or Spanish [12] version in comparison with the German [13], Polish [14] or Brazilian [16] version. The different structure of these language versions is critical for the maintenance of the validity and internal consistency of the questionnaire.…”

“…The existence of a disease-specific questionnaire like the CU-Q 2 oL facilitates the investigation of the parameters that drive HRQoL impairment. The CU-Q 2 oL is currently the only available CSU-specific quality of life instrument and is already available in several language versions [11,12,13,14,15,16]. The aim of this study was to develop a Greek version of the CU-Q 2 oL and to assess the relation between disease activity and HRQoL impairment.…”

“…Takie cechy psychometryczne spra wiają, że jest to dobre narzędzie do oceny uszczerbku na zdrowiu w przebiegu PPS. Do chwili obecnej kwe stionariusz został przetłumaczony i zatwierdzony do stosowania w języku niemieckim, hiszpańskim, pol skim, tureckim, greckim, bułgarskim, portugalskim (odmiana europejska i brazylijska), a inne wersje języ kowe poddawane są aktualnie walidacji [24][25][26][27][28]. Do stępne są także testy dla pacjentów z objawami obrzę ku naczynioruchowego [29].…”
