本研究的目的是比较三种不同光源治疗冬季抑郁症的相对疗效。 采用平衡不完全区组交叉设计，其中所有患者（n = 18）被随机分配到三种治疗条件中的两种：白色、红色和蓝色光。 采用汉密尔顿抑郁量表（21项）评定抑郁程度。数据表明，在2.3 × 10（15）光子/s/cm 2的光子密度下，白色光比红光或蓝光具有更大的治疗益处。 很明显，应该对更大的样本群体进行测试，以确认这一结果。 这一初步发现表明，目前用于光疗的光源不能通过缩小波长并将其移向可见光谱的任何一端来改善。
The aim of this study was to compare the relative therapeutic efficacies of three different light sources for treating winter depression. A balanced incomplete block crossover design was employed, whereby all patients (n = 18) were randomly assigned to two out of the three treatment conditions: white, red and blue light. The degree of depression was assessed by the 21-item Hamilton Depression Rating Scale. The date suggest that at a photon density of 2.3 X 10(15) phonton/s/cm2, white light has greater therapeutic benefit than red or blue light. It is clear that a larger sample population should be tested to confirm this result. This preliminary finding indicated that light sources currently in use for phototherapy could not be improved by narrowing the wavelengths and shifting them towards either end of the visible spectrum.
