Translation, adaptation, and preliminary validation of the Brazilian version of the Behavior Problems Inventory (BPI-01).
BACKGROUND
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.


CONCLUSIONS
BPI-01 showed good psychometric properties, with satisfactory preliminary indicators of reliability, convergent validity, and sensitivity for the diagnosis of atypical development.
