摘要

Objective This paper goal was to validate the Portuguese version (Brazil/Portugal) of the Anger, Anxiety, and Depressive Symptoms item banks of the Pediatric PROMIS(R) Emotional Distress domain (version 1.0) for the Brazilian and Portuguese pediatric population. Method The total of 1216 participants answered a self-applied version of the Portuguese Anger, Anxiety, and Depressive Symptoms item banks. Reliability was assessed through internal consistency, test-retest reliability, and total information curve (TIC). Confirmatory Factor Analysis (CFA) with a bifactor model was used to confirm construct validity and IRT assumptions. Item calibration was performed according to Graded Response Model (GRM). Differential Item Functioning (DIF) was analyzed according the participants' age, gender, health condition (healthy versus chronic disease), and language. Results Internal consistency reliability (Cronbach's alpha coefficient = 0.84) and test-retest reliability (intraclass correlation = 0.93) were accurate. Unidimensionality, Local Independency, and construct validity were verified by CFA (CFI = 0.93; TLI = 0.93; RMSEA = 0.05; chi(2) = 3052.4 with DIF = 557 and P value = 0.595). GRM was adjusted, and Emotional Distress had a satisfactory coverage. DIF was not significant. Conclusion The results obtained indicate the adequacy of the psychometric properties of the Portuguese version (Brazil/Portugal) of the Anger, Anxiety, and Depressive Symptoms item banks of the Pediatric PROMIS(R) Emotional Distress domain.
