结局指标
主要结局
Achieving recommended sleep levels
时间窗: 1 month
The main outcome measure was adapted from the Pittsburgh Sleep Quality Index (Buysse, Reynolds, Monk, Berman, \& Kupfer, 1989), and was designed to tap both quantity and quality of sleep. Sleep quantity was assessed by asking: "How many hours of actual sleep do you normally get on a night before school? _________ hours," "What time do you normally go to bed on a night before school? __________ pm," and "What time do you normally get up on a school day? __________ am."
次要结局
- Habit(1 month)
