Summary of "Improving health communication with photographic images that increase identification in three minority populations."

The homophily principle, that perceived similarities among people produce positive reactions, is a cross-cultural, global phenomenon. This study aimed to test the prediction that photographs that depict models similar to the target population improve health communication by increasing perceived identification in three racial/ethnic populations. Three separate nationally representative stratified samples (n = 1638) of African American, Hispanic and Native American adults were drawn from GfK's Knowledge Panel®. Participants read a message advocating increased physical activity and improved diets and completed measures on behavioral intentions, outcome and self-efficacy expectations and identification. The message contained photographs from a stock photograph service or photographs created for the research project to match the three minority populations, Real Health Photos (RHP). Structural equation modeling confirmed the theoretical hypothesis that RHP which matched the minority population increased behavioral intentions and was mediated by identification (P < 0.05) in all three racial/ethnic minority samples. Messages with only half of the matched RHP images had these same positive indirect effects among African Americans and Hispanics (P < 0.05). The impact of matching visual images in health messages to recipients derived from identification with the characters in images. Homophily and identification are hardwired, evolutionary, biological phenomena that should be capitalized on health educators with minority populations.

Medical and Biotech [MESH] Definitions

The process of generating three-dimensional images by electronic, photographic, or other methods. For example, three-dimensional images can be generated by assembling multiple tomographic images with the aid of a computer, while photographic 3-D images (HOLOGRAPHY) can be made by exposing film to the interference pattern created when two laser light sources shine on an object.

Planning that has the goals of improving health, improving accessibility to health services, and promoting efficiency in the provision of services and resources on a comprehensive basis for a whole community. (From Facts on File Dictionary of Health Care Management, 1988, p299)

The recording of images in three-dimensional form on a photographic film by exposing it to a laser beam reflected from the object under study.
