A Pilot Study of Color Preference and Drug Adherence in Psychiatric Outpatients on Neuropsychiatric Pharmacotherapy

Abstract The wavelengths of color stimulate the hypothalamus and induce psychological reaction. The relationship between color preference and psychiatric disorders has been studied for a long time. This pilot study performed to investigate mutual relationship between color preference and medication adherence on 155 psychiatric outpatients (65 for major depression disorder, 68 for anxiety disorder, 22 for bipolar disorder). We asked three questionnaires about a favorite color, a hatred color and self-assessment adherence, and conducted cross-analysis of the difference of color preference between result of this study and preceding study (2015). And we investigated the color distribution ratio of central nervous system therapeutics for oral solid formulation. The most favorite color was purple in major depressive disorder patients, and green in anxiety disorder and bipolar disorder patients. Purple-blue-green, the short wavelength colors were preferred in all subjects. This result presented a significant difference with preference of non-psychiatric patients. Of the 131 oral solid formulations, 46.6% were white color. So far, the favorite color has not yet been applied to patients’ medication. Because the favorite color of psychiatric patients is distinguished from that of non-psychiatric patients, the color preference might consider application in psychiatric medications.
