RESUMO
The homophily principle that perceived similarities among people produce positive reactions is a cross-cultural, global phenomenon. The prediction that photographs depicting models similar to the target population improve health communication was tested. Three nationally-representative samples (n = 1,796) of adults who are disabled, seniors, or considered overweight/obese were selected from GfK's Knowledge Panel®. Participants read a message promoting physical activity and improved diets and responded to assessments of behavioral intentions, outcome and self-efficacy expectations, and identification. Photographs from a stock photograph service versus photographs created for the research project to match the three populations, Real Health Photos (RHP), were included in the message. Structural equation modeling confirmed that RHP which matched the population increased behavioral intentions mediated by identification (p < 0.05) in the physically-disabled and overweight/obese samples. Messages with only half of the matched RHP images had these same positive indirect effects (p < 0.05). Matched visual images in health messages improved effectiveness by capitalizing on the homophily and identification processes. Health educators should leverage these hardwired, evolutionary, biological phenomena that extend to health status as well as race and ethnicity. For optimal effects, not all persons shown need to be homophilous to the target audience, reducing logistical difficulties in showing diverse persons of various types.

OBJECTIVE: We address cancer communication by creating and assessing the impacts of a theatrical production, When Cancer Calls (WCC ), anchored in conversations from the first natural history of a patient and family members talking through cancer on the telephone. METHODS: A national study was conducted using a multi-site and randomized controlled trial. An 80-minute video was produced to assess viewing impacts across cancer patients, survivors, and family members. Comparisons were made with a control video on cancer nutrition and diet. Pretest-posttest sample size was 1006, and 669 participants completed a 30-day follow-up impacts assessment. RESULTS: All five family and communication indices increased significantly for WCC . When compared to the placebo, average pretest-posttest change scores were higher for self-efficacy (775%), family fabric (665%), outside support (189%), and family communication (97%). One month following viewings, WCC participants reported 30% more conversations about cancer among patients and family members about cancer. CONCLUSION: A new genre of Entertainment-Education (E-E) was created that triggers positive reactions from audience members. Managing delicate and often complex communication about the trials, tribulations, hopes, and triumphs of cancer journeys is fundamentally important for everyday living. PRACTICE IMPLICATIONS: Unique opportunities exist to make WCC available to national and global audiences, create tailored curricula, and integrate these viewings into educational programs for patients, family members, and care-provider teams across diverse health, corporate, and governmental systems.

An online survey was conducted with health educators in Colorado to ascertain their needs and ability to access relevant stock art photographs for their print and electronic educational media. Health educators were dissatisfied with the cultural and demographic diversity of photographs available from their own sources or from commercial stock art websites. There was a perceived need for more photographs that would better represent their target populations. The health educators believed, furthermore, that representative visual images can help improve their message effectiveness.
