Objective:
The aim of this study was to translate and validate the Pediatric Daytime Sleepiness Scale (PDSS) into Brazilian Portuguese.
Methods:
The translation/validation process was carried out through translation, back translation, technical review, assessment of verbal comprehension/clarity of the scale by experts and a focus group, test-retest, and application of the tool. The reproducibility analysis was performed by applying the PDSS in test-retest; internal consistency was verified by applying the scale in 90 children and adolescents.
Results:
The mean score of the sum of PDSS questions was 15.6 (SD=5.0) points. The PDSS showed appropriate indicators of content validation and clarity for the Brazilian Portuguese version. The internal consistency analysis showed a Cronbach's alpha of 0.784. The PDSS showed adequate reproducibility. The PDSS scores showed a significant and negative correlation with time spent in bed (r=-0.214; p=0.023).
Conclusion:
The Brazilian Portuguese version of the PDSS shows satisfactory indicators of validity and can be applied in clinical practice and scientific research.
