Research suggests that nonverbal and verbal communication between health care professionals and patient can lead to improved patient outcomes. According to Atkin and Silk on page 496 some health care facilities, like hospitals are providing training and education materials to patients. The goal of hospitals doing this is to allow for patients to have a better outcome due to better communication skills. Over the years, there has been much research done on health communication. For example, researchers want to know if people are more effectively motivated by a positive message versus a negative message. Researchers examine ideas like, are people better motivated by ideas of wealth and safety or an idea of illness and death. Researchers are examining which dimensions of persuasive incentives are most influential: physical health versus economic, versus psychological, versus moral, versus social. (Atkin & Silk, 497) Impact of the Health Campaign-After research has been conducted and analyzed on the effects of health communication, it can be concluded that a health communication campaign that is requiring a behavior change causes the desired behavior change in about 7%-10% or more in the people who are in the campaign site than those who are in the control group. Also, the effects are stronger for adoption of a new behavior than cessation of a current behavior, about 12% higher. When assessing how affective a health campaign is, the key determinant is the degree of audience reception, the quality and quantity of the message, the dissemination channels, and the larger communication environment. It is possible that an audience can be more receptive to some messages than others. The media channel and how the message is reached by the audience can affect the effectiveness of the health campaign. (Atkin & Silk, page 498)  The efforts and effects of health messages and communication are often counter affected by alcohol and tobacco commercials. The advertisement for these items is often made to be glamorous and will contradict what was said in the health campaign. This can lead to the efforts of the health communication seem to be pointless. Health communication professionals are specifically trained in methods and strategies for effective communication of public health messages, with qualifications in research, strategic development, and evaluating effectiveness. Health communication is taught in master's and doctoral programs. The Coalition for Health Communication maintains a list of such programs. Scholars and practitioners in health communication are often trained in disciplines such as communication studies, sociology, psychology, public health, or medicine and then focus within their field on either health or communication. Practitioners are pragmatic and draw from social-scientific scholarship, theories from the humanities, and professional fields such as education, management, law and marketing (Maibach 2008).
