Abstract
Background: Charles Bonnet syndrome (CBS) is a condition characterised by the occurrence of vivid and complex visual hallucinations in individuals with visual impairment.
Objective: To explore the relationship between emotional distress and the perceived impact of CBS symptoms on participants' lives. We tested the hypothesis that heightened negative affect was associated with a more negative appraisal of CBS symptoms, increased self-reported loneliness, and poorer quality of life (QOL).
Design: Cross-sectional.
Methods: Participants recruited predominantly via vision-related charities rated their hallucinations and their impact on a Likert scale. Loneliness and negative affect were assessed with the Three-Item Loneliness Scale and Positive and Negative Affect Schedule. Health index (EQ-5D-3L) and vision-related QOL (VF-9) were also assessed. Correlation analysis and multi-variable regression determined the relation between survey responses.
Results: The majority of 126 respondents (81%) were aged 65+ years and 84% reported active CBS symptoms. Fifty-five percent of respondents rated impact of CBS as negative and no-one rated the impact as 'very pleasant'. A statistically significant correlation was found between impact of CBS and negative affect (p ⩽ 0.001; rho = -0.34) and impact of CBS and loneliness (p = 0.017; rho = -0.21). The relation between negative affect and CBS impact remained statistically significant when accounting for the impact of loneliness and the relationship between loneliness and CBS effect (p = 0.002, adj R2 = 0.1). A statistically significant correlation between loneliness and negative affect (p ⩽ 0.001; rho = 0.55) was also found.
Conclusion: Respondents experiencing negative emotions were more likely to perceive the impact of CBS symptoms as negative and report greater feelings of loneliness. Negative affect is an important consideration when assessing people with CBS.
背景：查尔斯-邦内特综合征（CBS）是一种以视力障碍患者出现生动而复杂的视觉幻觉为特征的疾病：目的：探讨情绪困扰与查尔斯-邦奈特综合征症状对参与者生活影响之间的关系。我们检验了以下假设：负面情绪的增加与对 CBS 症状更消极的评价、自我报告的孤独感增加以及生活质量（QOL）降低有关：设计：横断面：方法：主要通过与视力有关的慈善机构招募的参与者用李克特量表对其幻觉及其影响进行评分。孤独感和消极情绪通过三项目孤独感量表和积极与消极情绪表进行评估。此外，还对健康指数（EQ-5D-3L）和视力相关 QOL（VF-9）进行了评估。相关分析和多变量回归确定了调查回答之间的关系：在 126 名受访者中，大多数（81%）的年龄在 65 岁以上，84% 的受访者报告了活跃的 CBS 症状。55% 的受访者将 CBS 的影响评为负面，没有人将其影响评为 "非常愉快"。CBS 的影响与负面情绪（p ⩽ 0.001；rho = -0.34）和 CBS 的影响与孤独感（p = 0.017；rho = -0.21）之间存在统计学意义上的相关性。如果考虑到孤独感的影响以及孤独感与 CBS 效果之间的关系（p = 0.002，adj R 2 = 0.1），消极情绪与 CBS 影响之间的关系在统计上仍然显著。孤独感与负面情绪之间也存在统计学意义上的相关性（p ⩽ 0.001; rho = 0.55）：结论：经历过负面情绪的受访者更有可能认为 CBS 症状的影响是负面的，并报告出更强烈的孤独感。在评估 CBS 患者时，消极情绪是一个重要的考虑因素。
