Codes and Frequencies
For sample adults aged 18 and older, SLEEPFALL reports how often they had trouble falling asleep in the past week. This variable was included as a core item in the Adult Supplemental Items (ASI) section of the Sample Adult questionnaire, introduced in 2013.
Other sleep-related variables included in the ASI section include: SLEEPSTAY (number of times had trouble staying asleep, past week), SLEEPMEDS (number of times taking sleep medication, past week), and SLEEPREST (days woke up feeling rested, past week).
