Tradução e adaptação transcultural para a língua portuguesa do banco de itens interferência da dor do Patient-Reported Outcomes Measurement Information System pediátrico

Abstract

Introduction: Pain is a symptom of difficult assessment and management, especially in the pediatric population. The use of PROMs tools (measures of results reported by patients) have been shown to be a significant resource in the evaluation of this symptom and its impact on the quality of life of these patients. From the PROMs concept, the Patient-Reported Outcome Measurement System (PROMIS), a multidimensional instrument that assesses the interference of pain in the daily activities of children and adolescents, was developed. Objective: To translate and adapt cross-culturally to the Portuguese language the pediatric "Pain Interference" item bank. Methods: The scale translation was performed using the Functional Assessment of Chronic Illness Therapy (FACIT) methodology, which complies with the international standards for translation and adaptation of questionnaires and the recommendations of the PROMIS statistical center. A pre-test version was obtained from the transcultural translation and adaptation processes and applied to nine children followed in an outpatient clinic of pediatric specialties. Considering data obtained from a cognitive interview with the participants and from the observations about the comprehensibility of the scale during its application, a final version of the Portuguese language version was formulated. Results: Fron the thirteen items that make up the scale, eight items were readjusted so that the semantic, conceptual and cultural equivalence was achieved. Overall, items were easily read and understood by study participants. Expressions and grammatical particulars were revised and subtly altered so that a version for Portuguese language was guaranteed. Conclusion: Transcultural translation and adaptation ensured that the semantic, conceptual and cultural equivalence of the translated version was achieved. In this way, the pediatric "Pain Interference" bank of the Pediatric PROMIS can undergo validation and psychometric calibration studies so that its Portuguese version can be used in research and clinical trials that evaluate the interference of pain in children and adolescents.
