Multimedia health education to alleviate anxiety in patients with vitreous floaters
Abstract
Background: Vitreous floaters (VF) are common and typically benign but may cause significant anxiety due to misinterpretation of symptoms. This study aimed to evaluate the effectiveness of structured multimedia health education in reducing anxiety among patients with VF and to identify factors associated with anxiety severity.
Methods: This prospective quasi-randomized controlled study was conducted between December 2023 and April 2025. Patients with symptomatic VF were allocated to an enhanced multimedia education group or a standard care group based on calendar week. Anxiety was assessed using the State-Trait Anxiety Inventory (STAI-state), and visual-related quality of life (VRQoL) was measured using the National Eye Institute Visual Function Questionnaire-25 (NEI VFQ-25) at baseline and 3 months. Between-group differences in STAI-state change (ΔSTAI-state) were analyzed, and analysis of covariance (ANCOVA) was performed adjusting for baseline values. Multivariable logistic regression was used to identify factors associated with moderate-to-severe anxiety.
Results: A total of 309 participants completed the study. Both groups showed significant reductions in STAI-state scores; however, the reduction was significantly greater in the multimedia group (ΔSTAI-state: -5.22 vs. -1.09), with a between-group difference of -4.13 (95% CI: -5.21 to -3.05, p p < 0.001). No significant between-group differences were observed in VRQoL. Patients with higher education levels exhibited…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 309 participants or records.
