项目摘要

The aim of this study was as follows : First, to elucidate the prevalence rate of seasonal affective disorder (SAD) in adolescence. Second, to describe the symptomatologic characteristics of patients with SAD. Third, to clarify the regulatory factor of Global Seasonality Score (GSS).In the first study, first-year students from 7 Universities in 2003 and 2004 school years were divided into two groups : a high-GSS group scoring 13 and over, and a low-GSS group scoring 12 and below. Structured diagnostic interview using SCID-I was conducted for 40 students in each University. All students who belonged to the high-GSS had an interview. The rest of students were randomly selected from the low-GSS. In the second study, relationship among GSS, Temperament and Character Inventory (TCI), and climatic environment in which students graduated from high schools, was investigated using first-year students from 8 Universities in 2003 school year.Of the 12916 students from 7 Universities, 8596 respond … More ed GSS accurately. 151 of 202 high-GSS students and 110 of 118 low-GSS students had a structured diagnostic interview, and 7 and 1 fulfilled criteria for SAD and 12 and 2 for social phobia (SP), respectively. The estimate of prevalence of SAD was 0.96%, and there were no gender differences in prevalence. Students with SAD were associated with significant rates of SP.Of the 10871 students from 8 Universities, 6443 responded all questions accurately. Pass analysis using GSS score, amount of solar radiation, length of sunshine duration and 7 factors of TCI, showed that high GSS score was regulated by not sunshine environment, but low self-directedness, low cooperativeness, high self-transcendence, high novelty seeking and high harm avoidance. The profile of high GSS score shown here indicates "schizotypal character" in Cloninger's cube.These results indicate two possibilities : First, because of the estimated rate of SAD prevalence in first-year university students is approximately 1%, the number of patients with SAD may be quite a few. Second, there may be a common biological basis in SAD and SP. Less

本研究的目的是：首先，了解季节性情感障碍（SAD）在青少年中的患病率。第二，描述SAD患者的症状特征。第三，厘清全球季节性评分（GSS）的调控因素。在第一项研究中，来自7所大学2003和2004学年的一年级学生被分为两组：高gss组得分13分及以上，低gss组得分12分及以下。采用scid - 1对每所大学的40名学生进行结构化诊断访谈。所有属于高gss的学生都进行了面试。其余的学生是从低gss组随机抽取的。第二项研究以2003学年8所高校一年级学生为研究对象，对高中毕业生的GSS、气质与性格量表（TCI）与气候环境的关系进行了调查。在来自7所大学的12916名学生中，有8596名学生回答了…202名高gss学生中的151名和118名低gss学生中的110名进行了结构化诊断访谈，分别有7名和1名符合SAD标准，12名和2名符合社交恐惧症（SP）标准。SAD患病率估计为0.96%，患病率无性别差异。在来自8所大学的10871名学生中，6443名学生准确地回答了所有问题。通过对GSS评分、太阳辐射量、日照时数和TCI 7个因子的分析表明，高GSS评分不是受阳光环境的影响，而是受低自我导向、低合作、高自我超越、高求新和高避害的影响。图中GSS得分高的剖面显示了Cloninger立方体的“分裂型特征”。这些结果表明了两种可能性：第一，由于SAD在大学一年级学生中的患病率估计约为1%，因此SAD患者的数量可能相当多。其次，SAD和SP.
