Objective

To translate, perform the cross-cultural adaptation, and an initial validation of the Brazilian Portuguese version of PedMIDAS (BP-PedMIDAS).

Background

Pediatric Migraine Disability Assessment (PedMIDAS) was developed to measure the impact of migraine among children and adolescents.

Methods

PedMIDAS was subjected to translation, back-translation, and application of the questionnaire to 40 children and adolescents with migraine for confirmation validation. Once validated, the psychometric properties were tested through administration to 100 children and adolescents with migraine.

Results

The mean time required to complete BP-PedMIDAS was 135 ± 51 seconds. BP-PedMIDAS had a Cronbach’s coefficient α of 0.84 and a good stability (test–retest), with a good intraobserver and interobserver agreement (Pearson’s correlation > 0.80) and correlated with the frequency of the headaches. These results mirrored those seen with PedMIDAS, further validating the interchangeability of the versions.

Conclusion

BP-PedMIDAS has been shown to be useful for assessing disability in children and adolescents.
