DESCRIPTION (provided by applicant): This project focuses on the characteristics of audio narration for understanding multimedia in eHealth by seniors and others, using cancer prevention as the subject matter. Multimedia is an increasingly popular method for presenting cancer and other health information on the web and via CD/DVD. However, there is virtually no health literacy research on effective strategies for the design of multimedia. For example, in the 187 design guidelines published in NIH's Research-Based Web Design and Usability Guidelines, multimedia is briefly mentioned in just 4 guidelines. This project will address this significant yet understudied area of health literacy. Segments of the population are affected differentially by a multimedia presentation. Many older adults experience difficulties understanding speech due to changes in hearing sensitivity and cognition that affect speech processing. The conversational style of speech that is typically used in eHealth multimedia is very difficult for many persons to understand. Thus information that is critical to health decision processes may be missed. The speech produced when a speaker intentionally tries to improve intelligibility by speaking slowly and clearly, but without exaggeration, is called "Clear Speech". Clear Speech style has been repeatedly shown to enhance intelligibility of speech in numerous studies over the past 20 years. The goal of this project is to systematically evaluate the effectiveness of Clear Speech as a narration technique for eHealth multimedia for seniors and to disseminate the results through guidelines. The overall design of the study will be a mixed factorial with age as a between-subject variable and performance on tasks as a within-subject variable. The study will be divided into intelligibility, comprehension, retention and preference testing. 40 senior and 20 younger adults will participate in the project. Clear Speech narration is expected to be proven to be a cost-effective strategy to significantly enhance the ability of millions of consumers to obtain, process, and understand health information presented in eHealth programs.

描述（由申请人提供）：该项目着重于使用癌症预防作为主题的老年人和其他人在eHealth中理解多媒体的音频叙述的特征。多媒体是一种越来越流行的方法，用于在网络上和CD/DVD上呈现癌症和其他健康信息。但是，几乎没有关于多媒体设计有效策略的健康素养研究。例如，在NIH基于研究的Web设计和可用性指南中发表的187个设计指南中，仅在4个指南中简要提及了多媒体。该项目将解决这个重要的健康素养领域。人口的细分市场受到多媒体表现的不同影响。许多老年人由于听力敏感性和认知的变化而遇到困难，理解言语的变化，这会影响语音处理。对于许多人来说，通常在eHealth多媒体中通常使用的语音风格很难理解。因此，可能会错过对健康决策过程至关重要的信息。当演讲者故意通过缓慢而清晰的说话来提高清晰度时，发表的演讲被称为“清晰的言语”。在过去的20年中，已经反复证明了清晰的语音风格在许多研究中都可以提高语音的清晰度。该项目的目的是系统地评估清晰的语音作为老年人eHealth多媒体的叙事技术的有效性，并通过指南来传播结果。该研究的整体设计将是一个混合阶乘，将年龄作为受试者间变量和任务的性能作为受试者内部变量。该研究将分为可理解，理解，保留和偏好测试。 40名高年级和20岁的年轻人将参加该项目。预计清晰的语音叙述将被证明是一种具有成本效益的策略，可以显着增强数百万消费者获得，处理和理解EHealth计划中提供的健康信息的能力。
