Cross-cultural adaptation of the child development surveillance instrument "Survey of Wellbeing of Young Children (SWYC)" in the Brazilian context

Abstract

Introducion: Faced with the scarcity of culturally adapted, validated and feasible instruments for assessing child development for use in clinical practice in Brazil, more investment is needed to provide resources with good psychometric properties for clinical and scientific use. Objective: To analyze the cross-cultural adaptation process of the Child Development Surveillance Instrument "Survey of Wellbeing of Young Children (SWYC)" in the Brazilian context. Methods: SWYC is an instrument for monitoring development, behavior and risk factors for children younger than 65 months, consisting of questionnaires - Developmental Milestones, Parent's Observations of Social Interactions (POSI), Baby Pediatric Symptom Checklist (BPSC), Preschool Pediatric Symptom Checklist (PPSC) e Family Questions. The crosscultural adaptation followed the steps recommended in the literature and 45 parents from the first pre-test and 27 from the second pre-test participated. For the analysis of the properties of measurement was used factor analysis (Kaiser-Meyer-Olkin-KMO), calculation of convergent validity (Average Variance Extracted - AVE) and reliability (Internal consistency - Cronbach's Alpha - CA). Results: In the first pre-test, parents comprised only 31% of the items. The panel of experts reviewed and modified the questionnaires. In the second pre-test, the comprehension index was 77%, giving rise to the final version. The questionnaires Developmental Milestones, BPSC and PPSC were considered unidimensional (KMO = 0.62 to 0.95) and had a mean stroke of 0.52 to 0.73 and CA = 0.55 to 0.97. Conclusion: Analysis of the quality of the items, the convergent validity and the Internal consistency of the Brazilian version of the SWYC revealed satisfactory measurement properties, showing a promising instrument for clinical use and in research with children in Brazil.
