摘要
背景和目的：声音是影响痴呆症患者行为和心理症状表现的重要环境因素。最近关于声景效果的研究显示，在改善环境对痴呆症患者的影响方面取得了可喜的成果。然而，还没有对照研究旨在量化声景干预对居民结果的影响。本研究旨在评估声景干预对痴呆症患者和行为症状的可行性和影响：对增强型声景干预进行单盲重复测量随机对照试验。参与者为医院痴呆症专科病房的痴呆症患者。参与者被随机分配到早晚在房间里进行的增强型声景干预或照常治疗，随机化后每周进行2次基线周和4次主要和次要行为结果评估：结果：音景干预在招募、保留和实施方面都是可行的。随着时间的推移，两组患者的神经精神量表总分都有所提高（-5.89，95%CI -8.45至-3.28，p p = .042）：在这项试点研究中，声景增强疗法是一种可行且有效的非药物疗法，可以减少痴呆症患者对护理的抵触情绪，但并不能全面改善神经精神症状。我们需要进一步开展样本更大、持续时间更长的研究，以调查声环境增强对痴呆症患者的长期影响：临床试验注册号：NCT04809545。
Effect of Soundscape Augmentation on Behavioral Symptoms in People With Dementia: A Pilot Randomized Controlled Trial.
Background and objectives: Sound is an important environmental factor that influences the expression of behavioral and psychological symptoms of dementia. Recent research on the effect of soundscape has shown promising results in improving environmental impact on people with dementia. However, no controlled studies have aimed to quantify the effects of soundscape intervention on resident outcomes. The aim of this study was to assess the feasibility and impact of a soundscape intervention on people with dementia and behavioral symptoms.
Research design and methods: Pilot single-blind repeated-measures randomized controlled trial of an augmented soundscape intervention. Participants were people with dementia in a hospital-based specialized dementia unit. Participants were randomized to an augmented soundscape intervention delivered in their room in the morning and evening or treatment as usual, with 2 baseline weeks and 4 weekly post-randomization assessments of the primary and secondary behavioral outcomes.
Results: The soundscape intervention was feasible in terms of recruitment, retention, and delivery of the intervention. There were improvements in the neuropsychiatric inventory total scores over time in both groups (-5.89, 95%CI -8.45 to -3.28, p < .001), but no differences between groups. There were no significant group, time, or group × time differences for the Pittsburgh Agitation Scale (PAS) total score. For the PAS-resisting care subscale, there was a significant group × time difference, with a greater reduction in the soundscape group over the study period (-0.81, 95% CI -1.59 to -0.03, p = .042).
Discussion and implications: In this pilot study, soundscape augmentation was a feasible and effective nonpharmacological approach to reducing resistance to care in people with dementia, although it did not improve neuropsychiatric symptoms more globally. Further studies with larger samples and of longer duration are needed to investigate the long-term effects of augmented sonic environments on people with dementia.
期刊介绍：
Innovation in Aging, an interdisciplinary Open Access journal of the Gerontological Society of America (GSA), is dedicated to publishing innovative, conceptually robust, and methodologically rigorous research focused on aging and the life course. The journal aims to present studies with the potential to significantly enhance the health, functionality, and overall well-being of older adults by translating scientific insights into practical applications. Research published in the journal spans a variety of settings, including community, clinical, and laboratory contexts, with a clear emphasis on issues that are directly pertinent to aging and the dynamics of life over time. The content of the journal mirrors the diverse research interests of GSA members and encompasses a range of study types. These include the validation of new conceptual or theoretical models, assessments of factors impacting the health and well-being of older adults, evaluations of interventions and policies, the implementation of groundbreaking research methodologies, interdisciplinary research that adapts concepts and methods from other fields to aging studies, and the use of modeling and simulations to understand factors and processes influencing aging outcomes. The journal welcomes contributions from scholars across various disciplines, such as technology, engineering, architecture, economics, business, law, political science, public policy, education, public health, social and psychological sciences, biomedical and health sciences, and the humanities and arts, reflecting a holistic approach to advancing knowledge in gerontology.
