Abstract

A pilot study was conducted to evaluate the effectiveness of color light therapy as a treatment modality for individuals with treatment resistant depression. A secondary objective of the study was to determine the color preferences of the individuals and to assess whether the color preferences changed as a function of treatment. Pre and post measures of depression using the PHQ-9 found a significant decrease in depression after color light therapy (t (9) = 5.13, p < .01). Pre- and post-treatment measures of color preferences found significant changes in the preferences, with an increase of green (t (9) = -2.53, p < .05) and a decrease in blue (t (9) = 2.58, p < .05).
