BIS = Bergen insomnia scale; Pittsburgh SQI = Pittsburgh Sleep Quality Index; GSDS = General Sleep Disturbance Scale; PSQS = Postpartum Sleep Quality Scale; ISI = Insomnia Severity Index; ESS = Epworth Sleepiness Scale; Athens IS = Athens Insomnia Scale; SSC = Sleep Symptom Checklist.
Methodology reported as either: “Very good,” “Adequate,” “Doubtful,” “Inadequate” or “Not assessed” (NA).
Ratings for overall performance reported as either: sufficient (+), insufficient (–), inconsistent (±), or indeterminate (?); LoE = level of evidence using GRADE reported as: “High,” “Moderate,” “Low,” “Very low” or “Not assessed” (NA).
Recommendation: (A) evidence for sufficient content validity (≥6 domains assessed) and at least low-quality evidence for sufficient internal consistency (measures can be recommended for use); (B) measures categorized not in A or C (require further evaluation to assess quality prior to recommendation for use); (C) high quality evidence for an insufficient rated measurement property (not recommended for use).
