Measurement of children’s sleep and sleepiness

dditional research has recently demonstrated the psychometric properties of several childhood measures of sleep and daytime sleepiness.
Meltzer, L. J., Biggs, S. Reynolds, A., Avis, K. T., McLaughlin-Crabtree, V., Bevans, K. B. (2012). The Children’s Report of Sleep Patterns – Sleepiness Scale: A self-report measure for school-aged children. Sleep Medicine, 13, 385–389.
This study by Meltzer and colleagues (2012) was conducted to establish the psychometric properties of the Children’s Report of Sleep Patterns (CRSP-S), a self-report measure of daytime sleepiness for school-aged children. Analyses supported the internal consistency and the uni-dimensionality of the tool. Scale items were confirmed to cover a wide range of sleepiness experiences, with minimal redundancy, gaps, or bias against age, gender, or clinical group. Moreover, high test-retest reliability (0.82), as well as good construct and convergent validity was found. As such, the authors conclude that the CRSP-S is a reliable and valid self-report measure of daytime sleepiness for children
Dewald, J. F., Short, M. A., Gradisar, M., Oort, F. J., & Meijer, A. M. (2012). The Chronic Sleep Reduction Questionnaire (CSRQ): A cross-cultural comparison and validation in Dutch and Australian adolescents. Journal of Sleep Research, 21, 584-594.
Dewald and colleagues (2012) aimed to develop an English version of the Chronic Sleep Reduction Questionnaire, as well as assess the reliability and validity of both the Dutch and English versions of the tool. The questionnaire was administered to large Dutch and Australian samples, and analyses revealed good psychometric properties (reliability and validity) for both versions. Moreover, sleep variables were assessed through the completion of surveys, sleep diaries, and actigraphy over 5 school nights. A significant relationship between adolescents’ school grades and chronic sleep reduction was found, while there was weak or the absence of any associations between school grades and others sleep variables.
Biggs, S. N., Kennedy, J.D., Martin, A.J., van den Heuvel, C.J., Lushington, K. (2012). Psychometric properties of an omnibus sleep problems questionnaire for school-aged children. Sleep Medicine, 13, 390–395.
Biggs and colleagues (2012) sought to develop and assess the psychometric properties of a robust omnibus sleep problems questionnaire for school-aged children. The questionnaire was completed by parents of 1904 children aged 5 to10 years, and principal axis factoring was conducted to determine factor structure. Analyses revealed 6 subscales: Sleep Routine, Bedtime Anxiety, Morning Tiredness, Night Arousals, Sleep Disordered Breathing and Restless Sleep. Moderate to strong internal consistency for subscales, as well as adequate test-retest reliability was found.
