Insights

The Tucson Children's Assessment of Sleep Apnea Study (TuCASA) questionnaire is now validated for Brazilian children. This reliable tool aids in evaluating symptoms of sleep-disordered breathing (SDB) in clinical practice.

Area of Science:

  • Pediatric Sleep Medicine
  • Clinical Psychology

Background:

  • Sleep-disordered breathing (SDB) is a prevalent condition in children.
  • Accurate and accessible screening tools are crucial for early diagnosis and intervention.
  • The Tucson Children's Assessment of Sleep Apnea Study (TuCASA) questionnaire is a widely used tool for SDB screening.

Purpose of the Study:

  • To validate the Portuguese translation of the TuCASA questionnaire for the Brazilian population.
  • To assess the reliability and validity of the translated TuCASA for use in Brazilian children.

Main Methods:

  • The TuCASA questionnaire was translated into Portuguese and back-translated.
  • 62 children (aged 4-11 years) participated; 45 with SDB and 17 without, confirmed by polysomnography.
  • The Portuguese TuCASA was administered by a blinded interviewer; Cronbach's alpha and item exclusion effects were analyzed.

Main Results:

  • The translated TuCASA demonstrated satisfactory internal consistency with a Cronbach's alpha of 0.726.
  • No significant differences were found in TuCASA scores related to age or gender.
  • Convergent validity was satisfactory, with most correlations being positive and significant.

Conclusions:

  • The Portuguese version of the TuCASA questionnaire is a validated and reliable instrument for evaluating children with suspected SDB in Brazil.
  • The validated TuCASA can be effectively utilized in clinical practice for screening and assessment.
  • This study supports the use of culturally adapted screening tools in pediatric sleep medicine.

Sleep Apnea01:21

Sleep Apnea

Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
The condition is more prevalent among...
