The Relationship Between Time-Related Characteristics of Visual Impairment and Psychological Symptoms in Adults Who Are Blind

Abstract

Introduction The prevalence of depression among blind people is higher than in sighted populations. The purpose of this study was to investigate the associations between time-related characteristics of visual impairment (i.e., onset and duration), as well as depressive symptoms, fatigue, sleepiness, and stress, in the context of self-reported total blindness and the inability to perceive light exposure. Methods This study employed a cross-sectional design utilizing the combination of online survey and telephone survey. The Centre for Epidemiological Studies–Depression Inventory, the Fatigue Syndrome Inventory, the Epworth Sleepiness Scale, and the Perceived Stress Scale were selected for the self-reported questionnaires. For statistical analysis, independent t-tests, analysis of variance tests, Wilcoxon–Mann–Whitney tests, chi-square tests, multiple linear regression models, and multivariable ordinal logistic regressions were conducted using the R software program and its required packages. Results A total of 154 respondents completed the online and telephone surveys. Although the number of years of experiencing blindness showed negative correlations with the scores of fatigue ( r = −.16, p < .05), stress ( r = −.18, p < .05), and depressive feelings ( r = −.21, p < .05) in Model 1, the impacts of the onset of blindness on the depressive symptoms (β = −.02, p = .570) and the presence of severe depressive symptoms, OR = 1.42, 95% CI [0.49, 4.19], p = .518, were insignificant in Model 2. Discussion Blindness seems to be regarded as a more severe chronic condition which affects individuals’ psychological status. Given the effects of the limited range of social activities and daily tasks and the dramatically reduced accessible visual information inputs, the severe depressive symptoms in this group can be understood. Implications for Practitioners Regular counseling and psychological services monitoring depressive symptoms, chronic fatigue, and severe distress should be continued even after the completion of rehabilitation programs.
