====== Sleep quality (PSQI) ====== The [[https://en.wikipedia.org/wiki/Pittsburgh_Sleep_Quality_Index|Pittsburgh Sleep Quality Index]] was used to assess sleep quality of adult [[cohort|Lifelines]] participants ([[sections|section]]: [[Lifestyle & environment]]).\\ Note that the first 3 variables from the official PSQI were omitted here, because the same information could be derived from the Munich Chronotype Questionnnaire ([[Chronotype (MCTQ|MCTQ]]) also included in assessment [[1B]].\\ Other sleep-related data were collected using the [[Sleepiness (ESS)|Epworth Sleepiness Scale]], the [[Chronotype (CSM)|Composite Score of Morningness]] and the [[Sleep reduction (CSRQ)|Chronic Sleep Reduction Questionnaire]] (CSRQ only for children). \\ Several [[Sleep indices (PSQI, MCTQ, ESS)|sum scores]] on sleep behaviours are available for use. \\ Note that the PSQI for children was also performed in the context of an additional questionnaire on screen use and sleep quality ([[BLUQ]]). | **Questions English** | **Questions Dutch** | **Code** | **Variable** | **Assessment** | **Age** | | in the past month, on average how many hours of sleep did you get per night?
