 During [[1B|follow-up questionnaire 1B]] adult [[start|Lifelines]] participants completed questionnaires from the [[Sleep quality (PSQI)|Pittsburgh Sleep Quality Index]]. Researchers from [[https://www.researchgate.net/profile/Thom_Lysen|Erasmus MC]] used these questions to calculate the Pittsburgh Sleep Quality Index (PSQI), Munich Chronotype Questionnaire (MCTQ), and Epworth Sleepiness Scale (ESS). This syntax has been checked by Lifelines and some bugs have been removed ([[sections]]: [[Lifestyle & environment]] ([[Sleep quality (PSQI]], [[Chronotype (MCTQ)]], [[Sleepiness (ESS)]]) and [[secondary & linked variables]]).
-The sleep indices can be requested in the Lifelines catalogue or by email (data@lifelines.nl). When this data has been used in your research, you will have to include a reference to the the following paper:
