The external validity of the Morningness-Eveningness Scale for Children was analysed via objective measures of skin temperature, light exposure and motor activity with the ambulatory circadian monitoring methodology. A total of 138 adolescents (57 boys and 81 girls) aged 12-13 years, who in addition to completing the Morningness-Eveningness Scale for Children to determine their circadian typology wore a wrist activity device (Kronowise 3.0; Kronohealth SL) during school days and a weekend, participated. Circadian parameters, such as mesor, amplitude and acrophase, were estimated for skin temperature, light exposure and motor activity, as were sleep parameters, such as risetime, bedtime and social jetlag. The results indicated that during the weekend E-type adolescents experienced later acrophases in temperature, light and activity than I-type and M-type adolescents did, whereas boys experienced earlier acrophases in temperature and activity. When school weekdays were compared with the weekend, there was a weekend delay in the acrophases of temperature (1:03), light exposure (2:03) and activity (3:15). The results obtained in this study provide external validity for applying the Morningness-Eveningness Scale for Children in the naturalistic context of high school while considering sex and type-of-day differences as important variables in chronopsychological studies.
采用动态昼夜监测方法，通过皮肤温度、光照暴露和运动活动的客观测量，分析了儿童晨型-夜型量表的外部效度。共有138名12至13岁的青少年（57名男孩和81名女孩）参与研究，他们除了完成儿童晨型-夜型量表以确定其昼夜类型外，还在上学日和周末佩戴了腕部活动设备（Kronowise 3.0；Kronohealth SL）。对皮肤温度、光照暴露和运动活动的昼夜节律参数，如中值、振幅和峰值相位进行了估计，同时也对睡眠参数，如起床时间、就寝时间和社会时差进行了估计。结果表明，在周末，E型青少年在温度、光照和活动方面的峰值相位比I型和M型青少年出现得更晚，而男孩在温度和活动方面的峰值相位出现得更早。将上学日与周末进行比较时，温度（1:03）、光照暴露（2:03）和活动（3:15）的峰值相位在周末出现延迟。本研究所得结果为在高中自然环境中应用儿童晨型-夜型量表提供了外部效度，同时将性别和日期类型差异视为时间心理学研究中的重要变量。
