To determine whether light therapy during winter is beneficial to adolescents with symptoms of seasonal affective disorder (SAD).
The 3 largest colleges in Reykjavik, Iceland.
Eighteen college students, 18 and 19 years old, suffering from symptoms of SAD.
School attendance and self-reported change in indicators (concentration, ability to awaken in the morning, and frequency of breakfast).
Light therapy helped some of the students concentrate and wake up in the morning, usually only to a mild degree, but did not improve school attendance.
The lack of effect of light therapy on school attendance in a group of students with symptoms of SAD indicates that school attendance is influenced by several complex factors, of which seasonal disorders are not a major determinant, even in those most at risk.
确定冬季光疗法对患有季节性情感障碍（SAD）症状的青少年是否有益。
冰岛雷克雅未克最大的三所学院。
18名年龄在18至19岁之间、患有SAD症状的大学生。
出勤率以及自我报告的指标变化（注意力、早晨醒来的能力和吃早餐的频率）。
光疗法帮助一些学生提高了注意力并能在早晨醒来，通常只是轻度改善，但并未提高出勤率。
光疗法对一组有SAD症状的学生的出勤率没有影响，这表明出勤率受多种复杂因素影响，其中季节性障碍并非主要决定因素，即使对那些风险最高的人也是如此。
