126 patients suffering from winter depression participated in the study. Every second week patients completed the 13 item Beck Depression Inventory (BDI) in the period September to May in the years 1991 to 1994. Local weather data from this period were obtained from the Meteorological Institute, Copenhagen. No significant correlation was found between score on BDI and cloud cover, rainfall or atmospheric pressure. A significant correlation was found between score on BDI and minutes of sunshine, global radiation, length of daylight and temperature. This is in accordance with the theory, that lack of light is a contributing factor for development of winter depression.
126名患有冬季抑郁症的患者参与了这项研究。在1991年至1994年的9月至5月期间，患者每隔一周完成一次13项贝克抑郁量表（BDI）。该时间段的当地天气数据来自哥本哈根气象研究所。未发现BDI得分与云量、降雨量或气压之间存在显著相关性。BDI得分与日照时长、总辐射、日照长度和温度之间存在显著相关性。这与缺乏光照是冬季抑郁症发病的一个促成因素这一理论相符。
