Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Change in subjective rating of the device across a 3-week intervention
Lasso di tempo: Change in subjective rating of the device from baseline (pre; Day 0) to after 21 days of wearing it (post)
|
There will be a subjective rating of the phototherapy device using a series of questions assessing device's effect on sleep and next-day function at the end of the trial.
|
Change in subjective rating of the device from baseline (pre; Day 0) to after 21 days of wearing it (post)
|
|
Change in Insomnia Severity Index (ISI) scores across a 3-week intervention
Lasso di tempo: Change from baseline over the course of the study (after 21 days of wearing the device)
|
The ISI is a 7-item insomnia screening tool that is the gold standard for quantifying severity of clinical insomnia symptoms.
|
Change from baseline over the course of the study (after 21 days of wearing the device)
|
|
Change in objective sleep efficiency across a 3-week intervention
Lasso di tempo: Change from mean baseline period (first two weeks of wear) to post three weeks of wearing the phototherapy device.
|
Objective sleep efficiency will be measured with a wearable device (Oura ring) that is worn for the duration of the study and captures sleep and wake data using actigraphy.
|
Change from mean baseline period (first two weeks of wear) to post three weeks of wearing the phototherapy device.
|

Misura del risultato |
Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Change in mean sleep latency assessed using sleep diaries
Lasso di tempo: Change from mean baseline period (first two weeks of wear) to post three weeks of wearing the phototherapy device.
|
Sleep latency, or time taken to fall asleep, will be assessed using morning sleep diaries completed by the participant upon awakening.
The mean sleep latency during the baseline period (pre) will be compared to after three weeks of wearing the phototherapy device (post).
|
Change from mean baseline period (first two weeks of wear) to post three weeks of wearing the phototherapy device.
|
|
Change in Karolinska Sleepiness Scale (KSS) score
Lasso di tempo: Change from before intervention (pre) to post three weeks of wearing the phototherapy device (Day 21)..
|
The Karolinska Sleepiness Scale (KSS) measures situational sleepiness on a 9-point scale
|
Change from before intervention (pre) to post three weeks of wearing the phototherapy device (Day 21)..
|
|
Circadian Energy Scale (CIRENS) score
Lasso di tempo: Change from baseline (pre) to post three weeks of wearing the phototherapy device (Day 21).
|
CIRENS is a very short and simple chronotype measurement tool based on energy.
The CIRENS consists of two introspective questions about the usual energy level (very low, low, moderate, high, or very high, scored 1 to 5) in the morning and in the evening.
The difference between energy level scores (-4 to 4) felt by respondents in the evening and morning defines the chronotype score and classification.
|
Change from baseline (pre) to post three weeks of wearing the phototherapy device (Day 21).
|
|
Positive and Negative Affect Scales (PANAS) Positive Affect
Lasso di tempo: Change from baseline (pre) to post three weeks of wearing the phototherapy device (Day 21).
|
The Positive and Negative Affect Scales are brief screening measures that assess both positive and negative emotional experiences.
This scale will allow for separate assessment of impact on positive mood.
|
Change from baseline (pre) to post three weeks of wearing the phototherapy device (Day 21).
|
|
Positive and Negative Affect Scales (PANAS) Negative Affect
Lasso di tempo: Change from baseline (pre) to post three weeks of wearing the phototherapy device (Day 21).
|
The Positive and Negative Affect Scales are brief screening measures that assess both positive and negative emotional experiences.
This scale will allow for separate assessment of impact on negative mood.
|
Change from baseline (pre) to post three weeks of wearing the phototherapy device (Day 21).
|
|
Change in Fatigue Severity Scale (FSS) across a three-week intervention
Lasso di tempo: Change from baseline (pre) to post three weeks of wearing the phototherapy device (Day 21).
|
Fatigue Severity Scale (FSS) is a well-validated 9-item clinical measure that assesses overall levels of mental and physical fatigue, with answers ranging from 1- "Strongly Disagree" to 7-"Strongly Agree".
|
Change from baseline (pre) to post three weeks of wearing the phototherapy device (Day 21).
|
|
Change in Profile of Mood States (POMS) across a three week intervention
Lasso di tempo: Change from baseline (pre) to post three weeks of wearing the phototherapy device (Day 21).
|
The Profile of Mood States (POMS) is a psychological rating scale used to assess transient, distinct mood states.
The POMS measures six different dimensions of mood swings over a period of time.
These include: Tension or Anxiety, Anger or Hostility, Vigor or Activity, Fatigue or Inertia, Depression or Dejection, Confusion or Bewilderment.
A total score will be evaluated in addition to the individual items.
|
Change from baseline (pre) to post three weeks of wearing the phototherapy device (Day 21).
|
|
Change in Wake After Sleep Onset (WASO) assessed using morning sleep diaries over the duration of the study
Lasso di tempo: Change from mean baseline period (first two weeks of wear) to post three weeks of wearing the phototherapy device.
|
Wake after sleep onset (WASO), or the number of nocturnal awakenings, will be assessed using morning sleep diaries completed by the participant upon awakening.
The mean WASO during the baseline period (pre) will be compared to after three weeks of wearing the phototherapy device (post).
|
Change from mean baseline period (first two weeks of wear) to post three weeks of wearing the phototherapy device.
|
|
Change in sleep efficiency assessed using morning sleep diaries over the duration of the study
Lasso di tempo: Change from mean baseline period (first two weeks of wear) to post three weeks of wearing the phototherapy device.
|
Sleep efficiency, or the amount of time spent asleep during a sleep opportunity, will be assessed using morning sleep diaries completed by the participant upon awakening.
The mean sleep efficiency during the baseline period (pre) will be compared to after three weeks of wearing the phototherapy device (post).
|
Change from mean baseline period (first two weeks of wear) to post three weeks of wearing the phototherapy device.
|
|
Change in total sleep time assessed using morning sleep diaries over the duration of the study
Lasso di tempo: Change from mean baseline period (first two weeks of wear) to post three weeks of wearing the phototherapy device.
|
Total sleep time will be assessed using morning sleep diaries completed by the participant upon awakening.
The mean total sleep time during the baseline period (pre) will be compared to after three weeks of wearing the phototherapy device (post).
|
Change from mean baseline period (first two weeks of wear) to post three weeks of wearing the phototherapy device.
|
|
Change in morning refreshed feeling assessed using morning sleep diaries over the duration of the study
Lasso di tempo: Change from mean baseline period (first two weeks of wear) to post three weeks of wearing the phototherapy device.
|
Morning refreshed feeling will be assessed using morning sleep diaries completed by the participant upon awakening.
The mean refreshed feeling during the baseline period (pre) will be compared to after three weeks of wearing the phototherapy device (post).
