Reliability and validity of the bowel function index (BFI) for evaluating opioid-induced constipation: translation, cultural adaptation and validation of the Portuguese version (BFI-P).

CONCLUSIONS: This study had some limitations, namely, the criterion validity of BFI-P was not directly assessed; and the absence of a direct criterion for OIC precluded the assessment of the criterion based responsiveness of BFI-P. Nevertheless, BFI may importantly contribute to a better OIC screening and its Portuguese version (BFI-P) has been shown to have excellent reliability, internal consistency, validity and responsiveness. Further suggestions regarding statistically and clinically important change cut-offs for this instrument are presented. PMID: 27981871 [PubMed - as supplied by publisher]
