[Brazilian validation of the item banks on Sleep Disturbance and Wake Disturbance in the Patient-Reported Outcomes Measurement Information System (PROMIS)].

This study aimed to validate the Brazilian version of the item banks for Sleep Disturbance and Wake Disturbance from the Patient-Reported Outcomes Measurement Information System (PROMIS). Validation of these item banks used classical test theory, item response theory, calibrations of items according to the gradual response model proposed by Samejima, and analysis of Differential Item Functioning (DIF), with a sample consisting of 627 participants over 18 years of age. As for data quality, there were no missing data, five items from the Sleep Disturbance bank and four items from the WE bank showed a floor effect, and none of the banks showed a ceiling effect.

[Brazilian-Portuguese translation and cultural adaptation of the sleep and wake disturbances domains of the Patient-Reported-Outcomes Measurement Information System (PROMIS)].

Altered sleep and wakefulness affect individuals' mood, memory, and psychomotor performance and thus directly impact their quality of life. Tools to analyze the quality of these factors should be available for clinical evaluation. This study aimed to translate into Brazilian Portuguese and culturally adapt the Patient-Reported Outcomes Measurement Information System (PROMIS), specifically the sleep and wake disturbances domains.
