Primary |
Average Sleep duration (in hours) (past 2 weeks) |
Measured using actigraphy. Confirmation of time sleeping using consensus sleep diary, a 9-item diary developed through expert and patient collaboration, and Item 4 (How many hours of actual sleep do you get at night?) from the Pittsburgh Sleep Quality Index (PSQI), an 19-item self report on sleep quality and duration. |
Up to 2.5 months from the end of the intervention |

Primary |
Sleep fragmentation - sleep efficiency (%) (past month) |
Represented as a proportion. Sleep efficiency = (# hours slept/# hours in bed) X 100% Sleep efficiency can range from 0-100%, with higher sleep efficiency representing better sleep.
The numerator and denominator will be measured through actigraphy. Confirmation of the numerator (time sleeping) and the denominator (time in bed), will be confirmed using the consensus sleep diary, a 9-item diary developed through expert and patient collaboration. Confirmation of sleep efficiency will also use the sleep efficiency component of the Pittsburgh Sleep Quality Index (PSQI). The sleep efficiency component of the PSQI incorporates information from Questions 1, 3, and 4: # hours slept-question 4. # hours in bed-calculated from responses to questions 1 and 3. |

Primary |
Sleep fragmentation - number of sleep disruptions (past month) |
Sleep Disruptions: measured using actigraphy. Confirmation of sleep disruptions using self-report in the Consensus Sleep Diary, a 9-item diary and the Pittsburgh Sleep Quality Index (PSQI) sleep disturbance component. The PSQI sleep disturbance component (Question 5) assesses how often during the past month the respondent has had trouble sleeping due to (Wake up in the middle of the night or early morning; Have to get up to use the bathroom; Cannot breathe comfortably; Cough or snore loudly; Feel too cold; Feel too hot; Have bad dreams; Have pain; or Other reason(s)). Sleep disturbance component scores on the PSQI can range from 0 to 27, with 27 representing more sleep fragmentation (and therefore, worse quality sleep). |

Score on Pittsburgh Sleep Quality Index (PSQI) |
Subjective sleep quality will be measured using the Pittsburgh Sleep Quality Index (PSQI), which contains 19 self-rated questions. The 19 self-rated items are combined to form seven "component" scores, each of which has a range of 0-3 points. The component scores are summed to produce a global score (range 0 to 21). Higher scores indicate worse sleep quality. |

Secondary |
Score on the Perceived Stress Scale (PSS) |
Stress will be measured using Perceived Stress Scale (past month). The PSS has 10 items, completed using self-report. Individual scores on the PSS can range from 0 to 40 with higher scores indicating higher perceived stress. Scores ranging from 0-13 would be considered low stress; scores ranging from 14-26 would be considered moderate stress; scores ranging from 27-40 would be considered high perceived stress. |
Up to 2.5 months from the end of the intervention |

Secondary |
Score on the PROMIS Psychological Stress Experiences Survey |
Stress will be measured using the Patient-Reported Outcomes Measurement Information System (PROMIS) Psychological Stress Experiences Ped Short Form (SF) v1.0 (past 7 days), an 8-item self report. For PROMIS instruments, a score of 50 is the average for the United States general population with a standard deviation of 10 because calibration testing was performed on a large sample of the general population. A higher PROMIS T-score represents more of the concept being measured. For the Psychological Stress Experiences, a T-score of 60 is one standard deviation (SD) worse than average. |

Score on the Adolescent Sleep Hygiene Scale (ASHS) |
Sleep hygiene behaviors will be measured using the ASHS, a self-reported 32-item questionnaire designed to assess theoretically-based sleep hygiene domains thought to influence the sleep quality and quantity of youth aged = 12 years: physiological; cognitive; emotional; sleep environment; sleep stability; substance use; daytime sleep; and having a bedtime routine. Using a six-point ordinal rating scale ranging from 1 = never to 6 = always, adolescents indicate how often each item occurred during the past month. All but one of the items are reverse-coded, with higher scores indicating better sleep hygiene. The score is an average (range of 1 to 6) of all of the sub-scale scores with higher scores indicating better sleep hygiene. |

8.Score on the PROMIS Pediatric Anxiety Short Form 8a v2.0 |
Anxiety will be measured using the PROMIS Pediatric Anxiety Short Form 8a v2.0, an 8-item questionnaire assessing self-reported fear, anxious misery, and hyperarousal. Using a five-point frequency scale, ranging from 1 (never) to 5 (almost always), adolescents indicate how frequently or infrequently they felt various dimensions of anxiety(e.g., nervous, scared, worried) in the past 7 days. PROMIS instruments are scored using item-level calibrations. |
Up to 2.5 months from the end of the intervention |
|
Secondary |
Score on the PROMIS Pediatric Sleep-Related Impairment Short Form 8a v1.0 |
Subjective sleep-related impairment will be measured using the PROMIS Pediatric Sleep-Related Impairment Short Form 8a v1.0, an 8-item questionnaire focusing on self-reported perceptions of alertness, sleepiness, and tiredness during usual waking hours, and perceived functional impairments during wakefulness associated with sleep problems or impaired alertness. Adolescents rate various aspects of their sleep over the past 7 days on a 5-point frequency scale ranging from 1 (never) to 5 (always). PROMIS instruments are scored using item-level calibrations. |
Up to 2.5 months from the end of the intervention |

Secondary |
Score on MAAS-A (Mindfulness Attention Awareness Scale -Adolescents) |
Mindfulness will be measured using the MAAS-A, a self-reported 14-item questionnaire that measures the level of mindfulness, defined as "a receptive state of attention that, informed by an awareness of present experience, simply observes what is taking place." The MAAS-A is an adapted adolescent version of the validated Mindful Attention Awareness Scale (MAAS), which was developed for use with adult populations and considers mindfulness to be a one-dimensional construct. Using a six-point scale, ranging from 1 (almost always) to 6 (almost never), adolescents indicate how frequently or infrequently they currently have each experience. The score is the mean of the 14 items with higher scores reflecting higher trait mindfulness. |
