Brief summary
The present study will use a within-person, randomized cross-over experimental design to test the effects of exogenous melatonin supplementation on the sleep and daytime functioning of typically developing adolescents with short or disrupted sleep of behavioral origins (i.e., difficulty falling asleep, staying asleep, or premature waking resulting in short or disrupted sleep not attributed to an organic sleep condition).
Interventions
DIETARY_SUPPLEMENTMelatonin
Each subject will receive 3mg of melatonin 1 hour prior to bedtime for 12 consecutive nights
OTHERPlacebo
Each subject will receive a placebo 1 hour prior to bedtime for 12 consecutive nights

Inclusion criteria
* Self-identified sleep difficulties (e.g., difficulty falling asleep, staying asleep, or premature waking resulting in short or disrupted sleep). * Ages 13 to 17 years old * Able to understand, read, and write in English * Melatonin naive
Exclusion criteria

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Objective Sleep Duration During Melatonin Administration | Change between baseline and two weeks | Objective sleep will be measured via wrist-worn actigraphy worn nightly for 2 "run-in" nights followed by 12 consecutive nights after receiving melatonin (14 nights/2 weeks total). Changes in objective sleep duration would be demonstrated by either an increase or decrease in number of hours asleep compared to baseline |
| Change in Objective Sleep Duration During Placebo Administration | Change between baseline and two weeks | Objective sleep will be measured via wrist-worn actigraphy worn nightly for 2 "run-in" nights followed by 12 consecutive nights after receiving placebo (14 nights/2 weeks total). No change in objective sleep duration would be demonstrated compared to baseline |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Emotion Regulation During Melatonin Administration as Evidenced by the Emotion Regulation Index for Children and Adolescents (ERICA) | Change between baseline and two weeks | The Emotion Regulation Index for Children and Adolescents (ERICA) is a 16-item adolescent-report measure with scores ranging from 16 to 80 (higher scores indicative of better emotion regulation). This measure will be administered during baseline and after 14 days (2 weeks) including a 2 day "run-in" followed by 12 days of melatonin administration. It is expected that emotion regulation will improve after melatonin administration compared to baseline. Normal emotion regulation varies by individual. |
| Change in Emotion Regulation During Placebo Administration as Evidenced by the Emotion Regulation Index for Children and Adolescents (ERICA) | Change between baseline and two weeks | The Emotion Regulation Index for Children and Adolescents (ERICA) is a 16-item adolescent-report measure with scores ranging from 16 to 80 (higher scores indicative of better emotion regulation). This measure will be administered during baseline and after 14 days (2 weeks) including a 2 day "run-in" followed by 12 days of placebo administration. It is expected that emotion regulation will remain the same after placebo administration compared to baseline. Normal emotion regulation varies by individual. |
