Abstract
INTRODUCTION: Children with atypical development often present behavior problems that impair their psychosocial adaptation. OBJECTIVE: To describe the cultural adaptation to Brazilian Portuguese of the Behavior Problems Inventory (BPI-01), as well as preliminary indicators of instrument reliability and validity. METHODS: The process involved translation, back-translation, and cultural adaptation of the instrument. Psychometric properties (reliability and validity) were assessed comparing scores obtained with the BPI-01, the Wechsler Intelligence Scales for Children and Adults, the Child Behavior Checklist for Ages 6-18 (CBCL/6-18), and the Autism Screening Questionnaire (ASQ). The sample comprised 60 children (30 typically developing and 30 atypically developing). RESULTS: The cultural adaptation process was considered adequate. Internal consistency of the BPI-01 was satisfactory, with a Cronbach's alpha of 0.65 for the self-injurious behavior scale, 0.82 for stereotyped behaviors, and 0.91 for aggressive/destructive behaviors. Considering a mean frequency of 0.5, the receiver operating characteristic (ROC) curve revealed 80% sensitivity and 3% specificity in the stereotyped behavior scale, 50 and 10% in aggressive/destructive behaviors, and 76 and 6% in self-injurious behaviors, respectively. Low-to-moderate correlations were observed between BPI-01, ASQ, and CBCL/6-18 scores. CONCLUSION: BPI-01 showed good psychometric properties, with satisfactory preliminary indicators of reliability, convergent validity, and sensitivity for the diagnosis of atypical development.
