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 the vast majority of readers preferred the fotonovela over the existing brochure.

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.

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.

Stories are often used in health communication because of accumulating evidence of their potential to affect people's attitudes and health behavioral intentions. Similarity between the reader and the story's protagonist appears to positively influence narrative persuasion, but the exact role of similarity on persuasive outcomes is debated, as some research finds clear effects of similarity manipulations whereas others do not. Possibly, these mixed results were found because the similarity manipulations were not always relevant to the topic of the story.

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 controlled trial ( 303).

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 exposed to a health campaign first.

Recent studies suggest that health-related fotonovelas-booklets that portray a dramatic story using photographs and captions-may be effective health communication tools, especially for readers with a low level of literacy. In this experiment, effects on knowledge and behavioral intentions were assessed of a fotonovela originally developed for a Latin-American audience. Dutch readers from a low literacy group (N = 89) and a high literacy group (N = 113) were randomly assigned to one of three conditions: a fotonovela condition (all captions translated into Dutch), a traditional brochure condition (also in Dutch), and a control condition.

Successful doctor-patient communication relies on appropriate levels of communicative health literacy, the ability to deal with and communicate about health information. This article aims to describe the development of a narrative- and picture-based health literacy intervention intended to support older patients with limited health literacy when communicating during their primary care consultations. We performed a formative evaluation that included a review of the literature and interviews with stakeholders on relevant health literacy issues, qualitative studies with the target group, intervention planning, and a small-scale evaluation.

A systematic review was conducted to assess the available evidence for the effectiveness of interventions aiming to improve the comprehensibility of health-related documents in older adults (≥50) with different levels of health literacy. Seven databases were searched (2005 forward), and references in relevant reviews were checked. The selection procedure was conducted by 2 independent reviewers.

Article Synopsis
  • Low health literacy is prevalent among older adults and is linked to poor medication adherence, sparking a need for focused interventions to improve adherence in this demographic.
  • A systematic review analyzed existing reviews to assess the relationship between health literacy and adherence, finding inconsistent results and highlighting the challenges in establishing a clear connection.
  • While some adherence interventions have shown effectiveness, particularly those simplifying instructions, the overall quality of the studies was variable, and no definitive recommendations for specific interventions could be made.

Inadequate health literacy is a common problem among older adults and is associated with poor health outcomes. Insight into the association between health literacy and health behaviors may support interventions to mitigate the effects of inadequate health literacy. The authors assessed the association of health literacy with physical activity and nutritional behavior in community-dwelling older adults.

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 that puzzlement about health messages is related to keenness to talk about these messages, structured interviews were held with 30 black learners, ages 15 to 19, from Limpopo Province, South Africa, about the messages of six HIV/ AIDS posters and six HIV/AIDS radio advertisements from 'loveLife' or another South African health organisation.
