Sleep problems are common in adolescents. Studies have consistently demonstrated that sleep disturbances are prevalent, affecting up to 50% of this population. In this project, the investigators aim to map out sleep patterns, risk factors, and obstacles for sleep in adolescents, capturing the diversity of societal factors that shape the sleeping habits of adolescents. The investigators aim to recruit school-aged adolescents (aged 12-18 years old) in 12 countries across 15 research centres (N = 1000 per centre) to fill in the questionnaire covering sleep-wake patterns, sleep problems, mood, behavioral, daytime functioning and their attitude and perception towards sleep.

Patient Health Questionnarie-2
A 2-item tool used to screen for depression by assessing the frequency of depressed mood and anhedonia over the past two weeks. It includes the first two items of the PHQ-9, with scores ranging from 0 to 6. A score of 3 or more is considered the cut-off point for identifying potential depression.
Generalized Anxiety Disorder-2
A brief, two-item screening tool used to detect generalized anxiety disorder, with a recommended cut-off score of 3 or higher. A score of 3+ indicates a likely anxiety disorder, suggesting the need for further, more comprehensive assessment.
