SSC: Sleep Symptom Checklist. All variables: 0–3 Likert scale: the lower the value the better the functioning; 2ISI: Insomnia Severity Index, Scores >= 15 indicate moderate severity; 3ESFS: Empirical Fatigue Scale. The lower the scores the better the functioning. Range = 0–19; 4ESFS: Empirical Sleepiness Scale. The lower the scores the better the functioning. Range = 0–18; 5GAD: Generalized Anxiety Disorder Scale, 7: Sores >= 10 indicate a possible anxiety disorder; 6EPDS: The Edinburgh Postnatal Depression Scale: Scores >= 13 indicate possible depression.
