Translation and validation of the Pediatric Daytime Sleepiness Scale (PDSS) into Brazilian Portuguese.

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.
