A modified depression rating scale was distributed to a sample of the adult Finnish population (n = 1000) in November 1991. No dependence on latitude (60 degrees N-70 degrees N) was seen in the occurrence of depression. The depressed subjects (n = 54) were reevaluated the following May, and four cases with seasonal affective disorder were found. The results suggest that high latitudes with large variations in the daily lightperiod may not be responsible for high prevalence of major depression with a seasonal pattern.
1991年11月，一份经过修改的抑郁评定量表被分发给1000名芬兰成年人群体样本。在抑郁症的发生情况中，未发现与纬度（北纬60度至70度）有关。次年5月，对54名抑郁受试者进行了重新评估，发现了4例季节性情感障碍病例。结果表明，日照时长变化较大的高纬度地区可能并非季节性模式的重度抑郁症高发的原因。
