Jenkins Sleep Scale

Abstract

Designed as an efficient and brief instrument for use in research, the four-item question evaluates the frequency and intensity of certain sleep difficulties in respondents. Questions address difficulty falling asleep, frequent awakenings during the night, trouble remaining asleep, and subjective feelings of fatigue and sleepiness despite receiving a typical night’s rest. Though the questionnaire is short, developers suggest that its four items have been shown to possess good predictive value in previous studies [1]. However, with only four items, it cannot begin to address the entire spectrum of sleep disorders and should only be considered for use as a preliminary screening device.
