Educating marginalised adolescents about teenage pregnancy
Purpose One way to improve health education, particularly to marginalised groups, could be to use photo stories: booklets in dialogic form in which photos and captions tell a dramatic story about a health topic. Unlike health communication in testimonial form, in which a narrator tells a story to convey a health message, stories in dialogic form feature characters who communicate directly with each other. Printed health communication in dialogic …
Educating vulnerable communities about diabetes
Objectives: This study evaluated the effects of reading different versions of a fotonovela about diabetes in resource-poor settings in South Africa. Design: An experimental study was conducted with 411 participants, comparing a fotonovela with a younger protagonist, a similar fotonovela version with an older protagonist and a no message control condition. Differences between the two fotonovela versions were analysed for two age groups of readers …
How Do Patients Understand Questions about Lower Urinary Tract Symptoms? A Qualitative Study of Problems in Completing Urological Questionnaires
Lower urinary tract symptoms are common complaints in ageing people. For a urological evaluation of such complaints in men, the International Prostate Symptom Score (IPSS) is used worldwide. Previous quantitative studies have revealed serious problems in completing this questionnaire. In order to gain insight into the nature and causes of these problems, we conducted a qualitative study. Not only the purely verbal IPSS was studied but also two al…
Improving Health Literacy Responsiveness
Presenting attractive and useful health education materials in waiting rooms can help improve an organization's health literacy responsiveness. However, it is unclear to what extent patients may be interested in health education materials, such as brochures. We conducted a three-week field study in waiting rooms of three primary care centers in Groningen. Three versions of a brochure on doctor-patient communication were randomly distributed, 2250…
Deploying a Fotonovela to Combat Methamphetamine Abuse among South Africans with Varying Levels of Health Literacy
Poor health literacy in the Western Cape Province of South Africa is one of the main factors hampering methamphetamine (MA) use prevention efforts in the area, where the abuse of this drug is a major health and social problem affecting especially previously disadvantaged communities. In the first part of a two-part study, we compared a health-related fotonovela about MA to an existing brochure group and a control group. Main findings show that th…
The Impact of Receivers’ Nationality and Cultural Orientation on the Effects of Fear Appeals in Health Communication
Participants from the Netherlands (n = 52), China (n = 50), and South Africa (n = 166) either read a self-targeted or a family-targeted fear appeal message about chlamydia. Seven aspects of individual cultural orientation were measured, and six effects of the different messages. Interactions between nationality and target of threat were found on perceived severity, perceived susceptibility, and danger control. Only for perceived susceptibility, a…
Using Photo Stories to Support Doctor-Patient Communication
Older adults often have limited health literacy and experience difficulties in communicating about their health. In view of the need for efficacious interventions, we compared a narrative photo story booklet regarding doctor-patient communication with a non-narrative but otherwise highly similar brochure. The photo story booklet included seven short picture-based stories about themes related to doctor-patient communication. The non-narrative broc…
Using a fotonovela to battle crystal meth in South Africa
This study evaluated the effects of a health-related fotonovela about crystal meth (S-methamphetamine hydrochloride) among "Colored" people (an ethnic label for people of mixed race) in the Western Cape province of South Africa. Crystal meth use is most common among Colored people in this province and it is considered a major social problem. The fotonovela was compared to a no-message control group and a traditional brochure in a randomized contr…
Uncovering Factors Influencing Interpersonal Health Communication
Talking to friends, family, or peers about health issues might, among other things, increase knowledge of social norms and feelings of self-efficacy in adopting a healthier lifestyle. We often see interpersonal health communication as an important mediating factor in the effects of health campaigns on health behavior. No research has been done so far, however, on factors that influence whether and how people talk about health issues without being…
How peer conversations about HIV/Aids media messages affect comprehension and beliefs of young South African women
Most existent research on the effects of interpersonal discussions about health campaign messages is based on surveys. In this study, we analysed actual conversations about an HIV/AIDS poster to find out possible effects. Young South African women in 59 dyads (n = 118) participated in conversations about a deliberately puzzling HIV and AIDS poster that cautioned the target group to be faithful to one sexual partner. We measured their comprehensio…
Fear Appeals in Health Communication
This study investigated the influence of both nationality and cultural orientation on reactions to fear appeal messages including a self-targeted or a family-targeted threat. Participants from Spain (n = 138) and from the Netherlands (n = 127) either read a version of a story that accentuated the misery of a girl suffering from chlamydia, or a version that focused on her parents’ sorrow. Cultural orientation was assessed using a scale for measuri…
Overspecification in written instruction
A much debated question with respect to referential expressions is under what conditions speakers and writers produce overspecified expressions, i.e. expressions that contain more information than what is necessary for unique identification. In an earlier study we found that overspecifications facilitate the identification process for the understander, in particular if they contain complete object information and/or complete location information.…

HIV/Aids messages as a spur for conversation among young South Africans
HIV/AIDS messages are often deliberately puzzling so as to increase the chance for them to be used as food for conversation. The South African health organisation 'loveLife,' for instance, uses messages that include complicated rhetorical expressions in their media campaigns, reasoning that those who find the messages puzzling and wonder about their meaning will be inclined to discuss the messages with their peers. In order to test the assumption…

The influence of spelling conventions on perceived plurality in compounds
Dutch compounds with ‘e’ or ‘en’ as linking element between modifier and head were presented to mother tongue speakers of Afrikaans in an experimental setting that explored the possibility that these different spelling formats would suggest a singular or plural meaning of the modifier. The participants appeared to interpret ‘en’ in the linking element as an indication for singular, and ‘e’ as signifying plural. This outcome supported the findings…
Investigating culturally-oriented fear appeals in public information documents on HIV/Aids
Two public information texts including different fear appeals aimed at AIDS prevention were evaluated by participants from three countries: 147 participants came from the Netherlands, 109 from Spain and 179 from South Africa (varying ethnical backgrounds). The results of the experiment suggest that HIV/AIDS communication that emphasizes the severity of the disease and the vulnerability of the target audience can be successful, provided that the m…
