Self-reported sleep duration and timing: A methodological review of event definitions, context, and timeframe of related questions.

ABSTRACT:

Study objectives

Clinical and population health recommendations are derived from studies that include self-report. Differences in question wording and response scales may significantly affect responses. We conducted a methodological review assessing variation in event definition(s), context (i.e., work- versus free-day), and timeframe (e.g., "in the past 4 weeks") of sleep timing/duration questions.
