Verbally disruptive behaviors (VDB) are verbal or vocal behaviors that are inappropriate to the circumstances in which they are manifested. These behaviors are a source of concern because they disturb persons around the older person and may be an indicator of distress.
Three interventions were tried and compared to a control no-intervention phase. The interventions were: (1) Presentation of a videotape of a family member talking to the older person, (2) in vivo social interaction, and (3) use of music.
Thirty-two nursing home residents suffering from dementia and manifesting VDB were observed before, during, and after the interventions, and the duration of VDB was recorded. The behaviors decreased by 56% during the social interaction, 46% during the videotape, 31% during the music, and 16% during the no-intervention.
The effects of the interventions were clinically and statistically significant, indicating the importance of providing stimulating activities and a richer environment to cognitively impaired nursing home residents.
言语干扰行为（VDB）是指在其表现的情境中不适当的言语或发声行为。这些行为令人担忧，因为它们会干扰老年人周围的人，并且可能是痛苦的一个指标。
尝试了三种干预措施，并与无干预的对照阶段进行比较。干预措施包括：（1）播放家庭成员与老年人交谈的录像带，（2）现场社交互动，以及（3）使用音乐。
在干预前、干预期间和干预后观察了32名患有痴呆症并表现出言语干扰行为的养老院居民，并记录了言语干扰行为的持续时间。在社交互动期间，行为减少了56%；在播放录像带期间，减少了46%；在使用音乐期间，减少了31%；在无干预期间，减少了16%。
干预措施的效果在临床和统计学上具有显著性，表明为认知受损的养老院居民提供刺激性活动和更丰富环境的重要性。
