Using the Extended Parallel Process Model to create and evaluate the effectiveness of brochures to reduce the risk for noise-induced hearing loss in college students.

Brochures containing messages developed according to the Extended Parallel Process Model were deployed to increase intentions to use hearing protection for college students. These brochures were presented to one-half of a college student sample, after which a questionnaire was administered to assess perceptions of threat, efficacy, and behavioral intentions. The other half of the sample completed the questionnaire and then received brochures. Results indicated that people receiving the brochure before the questionnaire reported greater perceptions of hearing loss threat and efficacy to use ear plugs when in loud environments, however, intentions to use ear plugs were unchanged. Distribution of the brochure also resulted in greater perceptions of hearing loss threat and efficacy to use over-the-ear headphones when using devices such as MP3 players. In this case, however, intentions to use over-the-ear headphones increased. Results are discussed in terms of future research and practical applications.

Measuring cancer clinical trial understanding.

Researchers, practitioners, and participants in cancer clinical trials must have a clear understanding of clinical trials if participation in them is to be solicited ethically and effectively. A valid and reliable measure of cancer clinical trial understanding did not exist prior to a 2005 study conducted for the Coalition of Cooperative Cancer Groups. This report outlines a measure derived from that study, discusses the rationale for its component items, examines its psychometric properties, and demonstrates the relationship of this measure to the enrollment decision. Data from national samples of cancer survivors and the general public demonstrate the measure's validity and reliability. Results are discussed as they relate to patient understanding of clinical trials, informed decision making, and health communication processes.

Action tendency emotions evoked by memorable breast cancer messages and their association with prevention and detection behaviors.

Memorable messages about breast cancer sent by different sources, such as friends and family members, were analyzed for the action tendency emotions that they evoked. Negative emotions of fear, sadness, and anger, and positive emotions of hope and relief were analyzed for their associations with prevention and detection breast cancer behaviors. Messages that evoked fear were significantly more likely to be associated with detection behaviors, whereas messages that evoked relief were significantly less likely to be associated with detection behaviors than messages that did not evoke these emotions. These results are consistent with control theory and also show that friends and family are important sources of memorable messages about breast cancer.

Topics and sources of memorable breast cancer messages and their impact on prevention and detection behaviors.

Often, people are able to recall a message on a particular topic for a long period of time. These memorable messages have the ability to influence behavior when they are recalled from memory long after initial exposure. Knowing the topics and sources of the messages that are remembered about breast cancer can improve the efficacy of future breast cancer outreach. To this end, 359 women completed an online survey about memorable breast cancer messages. Most women (60%) recalled a memorable message, described it, identified its source, and noted whether it had resulted in prevention or detection behaviors. Four categories of message topics emerged: early detection (37.3%), awareness (30.9%), treatment (25.8%), and prevention (6%). Furthermore, five categories of sources of these memorable messages were found: media (35.5%), friends (22.2%), family (21.6%), medical professionals (15.2%), and others (5.5%). The media were a major source of all four topics of messages, although family members, friends, and the medical community were major sources for particular message topics as well. Memorable messages originating from medical professionals were substantially more likely to motivate detection behaviors than prevention behaviors. This research demonstrates that message topic and source both play roles in determining message recall as well as in determining how memorable messages impacted behavior.
