<p>Dr Edil Torres Rivera,</p><p>Editor-in-Chief of The Interamerican Journal of Psychology</p><p> </p><p> We are submitting the manuscript entitled “<strong>Cross-cultural adaptation of a distress assessment instrument in children undergoing painful procedures</strong>” for the appreciation of The Interamerican Journal of Psychology. This study aimed to translate, back-translate and cross-culturally adapt the Observational Scale of Behavioral Distress (OSBD) for distress assessment during painful events in Brazilian children undergoing clinical treatments.</p><p>Painful procedures are the major source of distress in pediatric patients and may have long-term consequences in behavior and development in children. The understanding that pain in children can be undertreated due to its difficult assessment has increased awareness of the need to use scales for the objective measurement of pain and distress. The OSBD instrument has been shown to be a valid and reliable behavior distress instrument for use with children in different countries. The present study presented a Brazilian version of OSBD that can be contribute to a better assessment of distress in Brazilian children undergoing painful procedures.  </p><p>The authors grant their permission to journal conducts editorial process.
