The present study aimed to analyze the construct validity of the Pediatric Daytime Sleepiness Scale (PDSS) for the evaluation of the daytime sleepiness construct in adolescents through confirmatory factorial analysis. The cross-sectional study was carried out with a sample of 773 adolescents aged 14 to 19 years, enrolled in the state schools of Paranaguá, Paraná, Brazil. We investigated the sex, age, school year, study shift, occupational status, socioeconomic level and daytime sleepiness. The PDSS questions were not normal (p <0.001) and the mean total score was 14.87 (5.62). With Schwarz's BIC adjustment indicators = 142,389 and Akaike's AIC = 105,389, the model reached the criteria of the global adjustment indicators of the model in the confirmatory analysis, in which RMSEA = 0.020; CFI = 0.986; TLI = 0.977; SRMR = 0.021, with 17 degrees of freedom, KMO = 0.8504 and Cronbach's Alpha = 0.737, with three correlations. We conclude that the construct validity of the PDSS remains valid and confirms its factor structure with only one factor. Thereby, it was verified that the operationalization of the construct sleepiness of adolescents through this scale is adequately conceptualized to the behavior of the age group.
本研究旨在通过验证性因素分析，分析儿童日间嗜睡量表（PDSS）在评估青少年日间嗜睡结构方面的结构效度。这项横断面研究以773名年龄在14至19岁的青少年为样本，他们就读于巴西巴拉那州巴拉那瓜市的公立学校。我们调查了性别、年龄、学年、学习班次、职业状况、社会经济水平和日间嗜睡情况。PDSS问题呈非正态分布（p<0.001），总平均分是14.87（5.62）。在施瓦茨BIC调整指标=142389和赤池AIC=105389的情况下，该模型在验证性分析中达到了模型整体调整指标的标准，其中RMSEA=0.020；CFI=0.986；TLI=0.977；SRMR=0.021，自由度为17，KMO=0.8504，Cronbach's Alpha=0.737，有三个相关性。我们得出结论，PDSS的结构效度仍然有效，并确认其只有一个因素的因素结构。因此，通过该量表对青少年嗜睡结构的操作化被充分概念化为该年龄组的行为。
