Translation and psychometric evaluation of the Spanish version of the problem areas in diabetes–pediatric version (PAID-Peds) survey

Background Metabolic control and psychological management of paediatric type 1 diabetes mellitus (T1DM) can be challenging over time. Development of an instrument to assess the youth-reported burden could aid in preventing T1DM-associated diseases. Methods The aim of this study was to translate and validate the Spanish version of the Problem Area in Diabetes Survey-Pediatric version (PAID-Peds). A multicentre, cross-sectional translation and linguistic validation study was performed on a sample of 30 participants aged 8-17 years with a minimum 1-year history of T1DM diagnosed at the Miguel Servet University Hospital in Zaragoza (Aragon, Spain), Ramón y Cajal University Clinical Hospital in Madrid (Spain), and Sant Joan de Déu Hospital in Barcelona (Catalonia, Spain). The qualitative validation consisted of translation into Spanish and back-translation into English of the Paid-Peds survey and subsequent administration to the sample population. Data were gathered on parameters related to sociodemographic characteristics and metabolic control. Validity, feasibility, and test-retest reliability were evaluated. Internal consistency was determined using Cronbach's alpha coefficient, test-retest reliability by means of interclass correlation, and paired samples using the Wilcoxon W-test. The study was approved by the ethics and research committees at each participating centre. Results The study assessed 30 children (46.7% female) with an average age of 13.33 [+ or -] 2.98 years; mean age at onset was 5.70 [+ or -] 3.62 years, and the mean disease duration was 7.63 [+ or -] 4.36 years. The mean score on the PAID-Peds survey was 42.88 [+ or -] 17.85. Cronbach's alpha coefficient was 0.90. Test-retest reliability measured by interclass correlation coefficient was 0.8 (95% CI: 0.63-0.90). No significant differences in total scores were found between test and retest (Wilcoxon W-test: 289; p = 0.051). Conclusions The Spanish version of the PAID-Peds survey is a feasible, valid, and reliable instrument to assess the youth-perceived burden of T1DM.
