Environmental color preference and influencing factors of inpatients with schizophrenia

Abstract

Objective To explore the preference and influencing factors of environment color of inpatients with schizophrenia. Methods A total of 1 320 schizophrenic inpatients were enrolled in the study.The self-made general questionnaire, the Eysenck personality questionnaire, the positive and negative symptom scale were used in this survey and the color preference was compared with the normal control group. Results (1)The preference degree was significantly different in green(Z=-2.587, P=0.010), blue(Z=-2.708, P=0.007), white(Z=-2.733, P=0.006) and grey(Z=-7.409, P<0.01) between the two groups, and the sequence of color preference was consistent(r=0.750, U=2.710, P<0.01). (2)Gender, age, place of residence, physical disease, starting age, disease subtype, positive symptoms, negative symptoms, hospitalization time, hospitalization frequency, psychoticism and neuroticism, internal and external factors were significantly related to color preferences(r=0.010-0.216 or r=-0.122- -0.054, P<0.05), which would be the influence factors to color preferences(β=0.104-0.055 or β=-0.091- -0.056, P<0.05). Conclusion The most significant color preferences for patients with schizophrenia are red and black, which may be related to their cognitive function and personality characteristics.
