Along with the results collected by Capture, athletes are prompted to enter feedback about their perceived sleep quality, appetite, pain levels, and psychological well being into the Kitman Labs app.
The PSQI is a self-administered questionnaire composed of 19 questions designed to assess seven components of perceived sleep status, including subjective sleep quality, sleep latency, sleep duration, habitual sleep insufficiency, sleep disturbance, use of sleep medications, and daytime dysfunction.
Patients were asked to rank their perceived sleep of the last night on a scale of 0-10, if this sleep quality was sufficient, and subsequently the RCSQ was performed.
In non-comatose patients (RASS −2 to +1), nurses daily asked patients to rate their perceived sleep of the last night on a numeric rating scale of 0 10.
It has also been found that observers perceived sleep deprived individuals as having more hanging eyelids, redder eyes, more swollen eyes, darker circles under the eyes, paler skin, more wrinkles/fine lines, and more droopy corners of the mouth [24].
The primary aim of this study was to systematically compare perceived sleep quality, sleeplessness behavior, sense of mastery, self-esteem, depression, subjective health, and effects of sleep loss in men and women with stable coronary artery disease (CAD).
Meta-analysis indicated a reliable placebo effect whereby placebo treatment led to improved perceived sleep onset latency (SOL; Hedges g = 0.272), total sleep time (TST; Hedges g = 0.322), and global sleep quality (GSQ; Hedges' g = 0.581), when compared with no treatment.
Subjects rated their perceived sleep quality and anxiety levels.
Both NLM and NLEE improved perceived sleep quality and anxiety level (P = 0.000), and NLM showed better than NLEE in perceived sleep quality (P = 0.01).
The inclusion of perceived sleep need and sleep deficiency defined by subtracting the actual sleep from their perceived sleep allowed us to explore this further.
Figure 1 shows respondents' perceived sleep quality while their loved ones were patients in the ICU.
