Adolescents tend to be much later chronotypes than other age groups. This circadian phase delay is attributed as much to biological as psychosocial factors. Because the consequences of this change on performance and health have been documented, questionnaires to identify morning and evening-type adolescents are necessary. The aim of the present study was to validate a Spanish version of the Morningness-Eveningness Scale for Children (MESC) by means of several relevant psychological variables as external criteria. A sample of 623 urban high school students completed the MESC and self-reported measures of sleep behaviors, subjective alertness, physical performance, and mood. On the whole, results indicate a good validity of MESC. Significant differences in the self-reported ratings between morning and evening types were obtained by time-of-day. These results provide preliminary support for the Spanish version of MESC.
青少年的昼夜节律类型往往比其他年龄组要晚得多。这种昼夜节律相位延迟在很大程度上归因于生物因素和社会心理因素。由于这种变化对表现和健康的影响已有文献记载，因此有必要通过问卷来识别早型和晚型青少年。本研究的目的是通过几个相关的心理变量作为外部标准，验证儿童晨型-夜型量表（MESC）的西班牙语版本。623名城市高中生的样本完成了MESC以及睡眠行为、主观警觉性、身体表现和情绪的自我报告测量。总体而言，结果表明MESC具有良好的效度。通过一天中的不同时间，早型和晚型在自我报告评分上获得了显著差异。这些结果为MESC的西班牙语版本提供了初步支持。
