A critical assessment of theories/models used in health communication for HIV/AIDS.

Most theories and models used to develop human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) communication are based on social psychology that emphasizes individualism. Researchers including communication and health scholars are now questioning the presumed global relevance of these models and thus the need to develop innovative theories and models that take into account regional contexts. In this paper, we discuss the commonly used theories and models in HIV/AIDS communication. Furthermore, we argue that the flaws in the application of the commonly used "classical" models in health communication are because of contextual differences in locations where these models are applied. That is to say that these theories and models are being applied in contexts for which they were not designed. For example, the differences in health behaviors are often the function of culture. Therefore, culture should be viewed for its strength and not always as a barrier. The metaphorical coupling of "culture" and "barrier" needs to be exposed, deconstructed, and reconstructed so that new, positive, cultural linkages can be forged. The HIV/AIDS pandemic has served as a flashpoint to either highlight the importance or deny the relevance of theories and models while at the same time addressing the importance of culture in the development and implementation of communication programs.

Perceived barriers to Internet-based health communication on human genetics.

The Internet has emerged as potential vehicle for distributing health communication to millions of individuals because it is interactive, user controlled, and offers breadth and depth of information. However, its widespread use by the public may be limited due to three overarching concerns: privacy and confidentiality, information accuracy and perceptions of credibility, including limited credibility of some government-sponsored web sites. To explore the potential of using the Internet, especially for delivering information on human genetics communication, 15 focus groups and one interview were conducted with African American and European American adult males and females in a southeastern town. We found that the participants recognized great potential in the Internet for health communication on human genetics, but they also voiced concerns about the credibility and accuracy of online information, lack of trust in many web sites, and fear of safeguarding privacy. Their concerns are summarized here, along with potential remedies health communicators could implement and should research further. The Internet cannot achieve its full potential for human genetics communication until the public's concerns are addressed and resolved.

Toward reducing youth exposure to tobacco messages: examining the breadth of brand and nonbrand communications.

Young people cannot escape prosmoking messages in today's society. From magazine advertisements to billboards to promotional products to storefronts, the pervasive landscape of tobacco-related communications is unavoidable. Despite increased restrictions on tobacco advertising and promotion in recent decades, including the 1998 Master Settlement Agreement (MSA), tobacco companies continue to employ an extensive array of marketing communications practices that can reach youth. Moreover, minors encounter tobacco messages not only from branded sources (those paid for by the tobacco firms), but also through nonbranded sources, such as smoking portrayals on television and in films and prosmoking websites. In this article, we critically examine the myriad and far-reaching tobacco messages that young people face. Although tobacco company marketing that can reach minors has undergone much research and public scrutiny, the combined impact of those messages along with nonbrand messages that positively portray smoking has received much less attention. Since all messages communicate, not just branded ones, it is important to examine the breadth of tobacco communications to which young people are exposed. We close by offering recommendations both for reducing youth exposure to protobacco communications and enhancing anti-youth-smoking efforts.

A descriptive analysis of 10 years of research published in the Journal of Health Communication.

This article describes the contents of the articles from the first decade of The Journal of Health Communication (JOHC). Three hundred and twenty-one published articles were reviewed and coded to determine the characteristics of the researchers, the types of research presented, the common health topics covered, and the research designs used. The results led to the following profile of a typical article. Its primary author is a U.S. academic. It probably focuses on smoking, HIV/AIDS, or cancer. It is an empirical research study, more likely to use quantitative, specifically survey methods, rather than qualitative methods. It probably is not driven by theory. It is much more likely to examine mass media communication than interpersonal communication. Its purpose is just as likely to be audience analysis as message design, as evaluation of a planned communication intervention. If its purpose is to evaluate a planned communication intervention however, that intervention is almost certainly a successful one.

Defining moments in risk communication research: 1996-2005.

Ten years ago, scholars suggested that risk communication was embarking on a new phase that would give increased attention to the social contexts that surround and encroach on public responses to risk information. A decade later, many researchers have answered the call, with several defining studies examining the social and psychological influences on risk communication. This article reviews risk communication research appearing in the published literature since 1996. Among studies, social trust, the social amplification of risk framework, and the affect heuristic figured prominently. Also common were studies examining the influence of risk in the mass media. Among these were content analyses of media coverage of risk, as well as investigations of possible effects resulting from coverage. The use of mental models was a dominant method for developing risk message content. Other studies examined the use of risk comparisons, narratives, and visuals in the production of risk messages. Research also examined how providing information about a risk's severity, social norms, and efficacy influenced communication behaviors and intentions to follow risk reduction measures. Methods for conducting public outreach in health risk communication rounded out the literature.

Factors associated with patients' perceptions of health care providers' communication behavior.

We examined patients' ratings of communication with health care providers by sociodemographic characteristics, health care access, and health status. Data were from a national, population-based survey, the 2003 Health Information National Trends Survey (HINTS). The survey was administered to 6,369 adults from a representative sample of U.S. households. Linear regression analysis was conducted using SUDAAN. None of the sociodemographic variables were significantly associated with patients' ratings of providers' communication behavior in the linear model. Ratings of health care providers' communication behavior, however, were significantly higher among respondents with health insurance (p = 0.007) and those with a usual source of health care from whom they consistently sought care (p < 0.001). Ratings of provider communication were significantly lower among respondents who perceived their general health to be fair or poor (p < 0.001) and among those respondents with greater depressive symptoms (p < 0.001). Differences in patient ratings of health care providers' communication by health care access and health status suggest the potential for disparities in health outcomes.

The status of clinic-based STD patient education: the need for a commitment to innovation in health communication.

Although knowledge of safer sex practices is increasing in high-risk populations, such as STD clinic patients, this knowledge does not often translate into behavior change. As a result, STD reinfection rates among clinic patients remain high, resulting in large numbers of return patient visits. As part of a study to evaluate strategies for improving clinic-based education for patients with STDs, we conducted formative research interviews with inner-city clinic managers or other key staff to identify opportunities for and barriers to enhancing STD patient education. These interviews revealed that most of the inner-city clinics had not introduced any new or innovative health communication strategies in the last several years. A primary barrier to innovation appeared to be the belief that patient needs were sufficiently addressed through one-on-one counseling, an assumption that does not take into account the limitations of this form of provider-patient communication. Another barrier was the emphasis placed on maintaining clinic flow, with little consideration given to how it might be altered to accommodate new educational approaches. We offer recommendations to encourage STD clinics to experiment with new and potentially more powerful health communication methods and to encourage the CDC and other funders to alter their STD service priorities toward improvements in health communication and education. We also offer steps that health communication specialists can take in helping clinics and funders move toward these goals.

Language background and communication skills of medical students.

OBJECTIVE: The increasing proportion of medical students whose primary language is other than English and recent reports of poor communication skills of medical graduates has generated community concern about the methods of selection of students and their communication skills training. This paper examines the relationship between language background and examination performance in oral communication skills in Year 5 medical students. METHOD: Questionnaire data from all Year 5 students in the 1992 general practice terms were matched to examination results. RESULTS: Seventy percent of students responded. Most students whose primary language was not English passed, although some required remedial communication skills tuition. The most powerful predictors of poor performance were recent arrival in Australia and living in an environment where English was not spoken at home. CONCLUSION: Students with poor English oral communication skills should be encouraged to speak English away from the medical school and should be offered additional tuition so that their skills in other languages are not lost to the health-care system.

A survey of interprofessional education in communication skills in health care programmes in the UK.

There is considerable evidence to indicate that patient satisfaction is directly related to the communication skills of health care providers. However, communication is an area in which health care practitioners often fail to meet patients' needs. Interprofessional education (IPE) is advocated as one way of improving health care communication for the consequent development of interprofessional care. However, poorly planned and delivered IPE can reinforce professional differences, so it is imperative that its introduction is based upon sound evidence of local need, opportunity and resources. A multidisciplinary and cross university project was designed to identify opportunities for, and best practice in, IPE in communication skills amongst undergraduate health care practitioners within one Workforce Development Directorate (WDD) in England. Methods included a comprehensive literature review of relevant educational initiatives, together with telephone and e-mail interviews with key informants in higher education institutions (HEIs) across the UK. This paper reports the findings from the interviews. Based upon these findings, a series of recommendations are made for the planning, implementation, and evaluation of IPE in communication skills, which should be taken into account by local curriculum planning groups.

Using a modified course experience questionnaire (CEQ) to evaluate the innovative teaching of medical communication skills.

SETTING: At the Faculty of Medical Sciences, The University of the West Indies, St Augustine first-year students take two courses in health communication. In the Centre for Medical Sciences Education students completed a course experience questionnaire. This instrument is potentially useful in evaluating innovative programmes and securing support for their development. CONTEXT: The Faculty of Medical Sciences, The University of the West Indies, St Augustine was the first of three campuses to introduce compulsory health communication courses in 1995. Using a modified form of the 25-item course experience questionnaire (CEQ25) (Broomfield & Bligh, 1998) normally employed in overall degree or course evaluation, this study developed a 30-item questionnaire (CEQ30) to test its applicability to the evaluation of medical communication skills teaching MEASURES: In 1997 - 1998 medical, dentistry, veterinary medicine and pharmacy students completed the original short form of the CEQ25 including five items specific to medical communication skills teaching. Students used a five-point Likert scale ranging from one, indicating that they strongly disagreed with the statement, to a score of five, reporting that they strongly agreed with the statement. Principal Components Analysis with Varimax rotation analysed the scale structure of the evaluation tool. RESULTS: The principal components factor analysis of responses (n = 165) broadly confirmed five of Broomfield and Bligh's six factors, but identified a sixth factor in their original instrument (appropriate assessment) that split into two, and a seventh factor, use of available materials and resources. CONCLUSION: The modified CEQ30 is a reliable instrument with which to evaluate a course in medical communication skills, and encourage reflection on teaching and course design. Its use is applicable to medical courses during overall curriculum change and innovation in a medical school.

Narrative skills of children with communication impairments.

BACKGROUND: Narrative assessment is sensitive to the communication impairments of children with specific language impairment and those with autistic spectrum disorders. Although both groups of children tend to show deficits in narrative, it is unclear whether these deficits are qualitatively different and how language and pragmatic ability may impact on narrative competence. Comparing these two groups of children with children who exhibit pragmatic language impairment without autism may help to clarify these issues. AIMS: This study explored the relationship between structural language ability and pragmatic competence in narrative in children with communication impairments and typically developing children. METHODS AND PROCEDURES: Diagnostic status was determined using the Children's Communication Checklist. All children were asked to generate a narrative to the wordless picture book Frog, Where are You? (Mayer 1969). Narratives were analysed according to their global structure, local linguistic structure and the child's ability to provide evaluative comments, especially about mental or emotional states. OUTCOMES AND RESULTS: No group differences were seen in global structure or evaluation. Children with specific language impairment and autistic disorder made more syntactic errors, and children with autism were significantly more likely to provide ambiguous references in the story. No significant relationships were evident between the Children's Communication Checklist and narrative measures. The complexity of language used was related to evaluation in the clinical groups. CONCLUSIONS: Narrative is a good way of assessing linguistic ability in older children with communication impairments. Core language abilities rather than pragmatic skill or diagnostic status are likely to influence narrative development.

Staff communication with people with intellectual disabilities: the impact of a work-based training programme.

Previous studies have identified changes that front-line service staff could usefully make to enhance their communications and those of their clients who have intellectual disabilities. These were incorporated into a training programme delivered in the workplace that involved a self-selected group of 24 experienced staff working either in small-scale residential settings and day centres. Analysis of video-recordings made before and after training showed that although most clients had become more active communicators (particularly when they were engaged in shared activities with staff), significant changes in staff behaviours as a whole were not observed. However increased responsiveness from staff did correlate significantly with increases in the client's communication acts. In addition, qualitative reports from staff and tutors pinpointed specific changes that staff had made. The difficulties of evaluating changes in staff-client communications are discussed and four features for training staff in communication are identified as essential; namely, it should be work-based, client focused, mentor-guided, and effective strategies documented and shared.

Enhancing communication in jargon aphasia: a small group study of writing therapy.

People with jargon aphasia have severely disordered and incomprehensible speech that may be resistant to therapeutic intervention. In this study, we treated written output and examined whether it assisted communication for these clients. In stage one of the study, anagram sorting, delayed copying and lexical decision tasks were used to investigate the residual knowledge of written words in a group of ten people with jargon aphasia. Evidence of the presence of orthographic knowledge was taken as an indication that writing might be a useful focus for therapy. This hypothesis was explored in stage two with six clients. A personally useful vocabulary was selected for each, and copying, word completion and written picture-naming tasks were used in therapy to improve written production of these words. The clients made progress in written naming. However, they showed little change on a 'message' assessment that tested their ability to use the written words to convey messages. Stage three targeted communicative writing. Here, three of the clients received 'message therapy', which encouraged them to relate treated words to functional messages and to communicate them to a partner. The clients improved on the message assessment and observation of their communication and reports from relatives suggested that they made functional use of writing in a range of communication settings.

Relationship between gestures and words in children with Down's syndrome and typically developing children in the early stages of communicative development.

BACKGROUND: Previous research has emphasized the importance of gesture in early communicative development. These studies have reported that gestures are used frequently during the first two years of life and may play a transitional role in the language acquisition process. Although there are now numerous descriptions of the relationship between gesture and the developing language system in typically-developing (TD) children, relatively little is known about the nature and early development of the gesture-language system in children with developmental disorders involving specific profiles of language delay and/or impairment. PRIMARY OBJECTIVE: The aim of this study is to compare early word and gesture use in children with DS and in typically-developing children to investigate potential differences in the relationship between gestural and verbal communication in early language development. METHODS AND PROCEDURES: Ten children from upper-middle class families participated in the study. The five children with DS (3 boys and 2 girls) had an average chronological age of 47.6 months, an average mental age of 22.4 months, and an average language age of 18 months. Each child with DS was matched to a typically developing child on the basis of gender, language age, and observed expressive vocabulary size. Children were videotaped for 30 minutes as they interacted spontaneously with their mothers. All communicative and intelligible gestures and words produced by the children were transcribed from the videotapes. Data analyses focused on: a) overall production of gestures and words (i.e., gesture and word tokens); b) the size of children's gestural and verbal repertoires (i.e., gesture and word types); and c) production and informational content of gesture-word combinations. MAIN OUTCOMES AND RESULTS: Although children with DS had significantly smaller gestural repertoires than their language age-matched peers, there was no reliable difference between the two groups in the overall use of gesture. In addition, with DS produced two-element combinations (primarily gesture-word combinations) and did so at a rate comparable to that observed among their TD counterparts. However, no two-word combinations were observed among children with DS, and there were also group differences in the information contained in children's gesture-word combinations. CONCLUSIONS: Taken together, these findings suggest that in addition to the well-documented global delays in early communicative development, children with DS may exhibit additional pockets of delay, specifically in making the transition from one- to two-word speech. Results are further discussed in terms of their implications for understanding the organization of the developing gesture-language system and for the assessment of gesture in young children with communicative delays and disorders.

Written communication in undifferentiated jargon aphasia: a therapy study.

A subject, R.M.M., with a 2-year history of jargon aphasia is described. At the beginning of this study she had minimal meaningful spoken output and showed little awareness of her speech despite having relatively well-preserved auditory comprehension. Her spoken output had proved resistant to earlier periods of therapy. In contrast, R.M.M.'s written output showed some ability to access orthographic information and monitoring of this modality was shown by an acute awareness of her errors. A 3-stage therapy programme is described. This was designed to improve R.M.M.'s writing of single words and to encourage use of writing as an alternative means of communication. The initial stage of therapy aimed to increase R.M.M.'s access to written word forms by use of picture stimuli. She showed significant improvement in writing treated items in response to pictures both immediately after therapy and at re-assessment 6 weeks later. Despite the acquisition of these skills, R.M.M. failed to use them in communicative contexts. A second stage of therapy replicated the results of the first and sought to facilitate R.M.M.'s functional use of her written vocabulary by asking her to write words to spoken questions. She again showed improved written naming of the treated items and could now produce written names appropriately in a questionnaire-type assessment. Generalization of this ability extended to items that had not been trained in this way. Functional use of writing in everyday communication remained absent, however. The final stage of therapy made explicit the potential links between items which R.M.M. could now write and functional messages which they might convey. She again showed significant changes in the acquisition of new vocabulary and, encouragingly, progress was also seen in her use of the strategy in functional communication. R.M.M.'s speech is almost entirely incomprehensible. It has remained unchanged for 2 years and has not responded to therapy. Relatively well-preserved auditory comprehension and good monitoring of written output allowed therapy to effectively target a small written vocabulary. Despite significant progress in the acquisition of new items, transfer of this skill to functional communication was initially absent. Further therapy which specifically targeted the impairment causing this failure was needed before functional use was seen. The potential for treating written output in cases of jargon aphasia which have been resistant to therapy for spoken language is discussed.

Evaluating the use of TalksBac, a predictive communication device for nonfluent adults with aphasia.

This paper describes the design and evaluation of a computer-based communication system called 'TalksBac' with four nonfluent adults with aphasia. Despite the increased availability of computer-based augmentative and alternative communication (AAC) devices, their use with adults with aphasia is limited as few devices have been designed for this population. The TalksBac system was designed specifically for nonfluent adults with aphasia and was used by four nonfluent aphasic individuals for a period of 9 months. The TalksBac system is word-based and exploits the ability of some nonfluent individuals with aphasia to recognize familiar words and short sentences. The system consists of two programs. Personal sentences and stories are entered into the TalksBac database by use of a 'carer program'. The 'user program' assists the nonfluent aphasic user to retrieve these prestored conversational items by offering probable items based on previous use of the system. The database has a hierarchical structure, but the links to individual items adapt automatically to reflect usage by individual users over time. Four nonfluent adults with aphasia were selected to participate in the study. Each subject was assessed by use of a battery of tests to provide pre-intervention data about their comprehension, expression and communication skills. Subjects and their carers were trained to use the TalksBac system and were involved in developing personalized databases. They were supported in use of the personalized systems for an intervention period of 9 months. At the end of this period, subjects' communication skills wre reassessed by use of a battery of tests. Clients' conversational abilities with and without the TalksBac system were also compared to see if use of TalksBac did augment their conversation and allow the aphasic partner to participate more fully within conversations. This was done by analysing videotaped conversations between subjects and non-aphasic partners. Results from the formal assessments indicated that there was little change in the underlying comprehension and expressive abilities of the subjects. An analysis of videotaped conversations showed that 1 subject was unable to carry out conversations using TalksBac independently, so the data for this subject was not included in the results of the analysis of conversations. Results from the video analysis for the remaining three subjects indicated that when using the TalksBac system, the conversational abilities of two subjects improved. The conversational abilities of the other subject were not enhanced by using the system as he had developed his own nonverbal strategies which he found to be more effective. This study has shown that TalksBac has the potential to augment the communication abilities of nonfluent adults with aphasia, who have not been able to develop their own compensatory strategies. Work continues to improve the efficiency of the software and to develop techniques to facilitate the carers' ability to generate conversational information for the system.

Neural differentiation, NCAM-mediated adhesion, and gap junctional communication in neuroectoderm. A study in vitro.

We studied the development of NCAM and gap junctional communication, and their mutual relationship in chick neuroectoderm in vitro. Expression of NCAM, as detected by monoclonal and polyclonal antibodies, and development of junctional communication, as detected by extensive cell-to-cell transfer of 400-500-D fluorescent tracers, occurred in cultures from stage-2 embryos onward. Both expressions presumably required primary induction. The differentiating cells formed discrete fields of expression on the second to third day in culture, with the NCAM fields coinciding with the junctional communication fields delineated by the tracers. Other neural differentiations developed in the following order: tetanus toxin receptors, neurofilament protein, and neurite outgrowth. Chronic treatment with antibody Fab fragments against NCAM interfered with the development of communication, suggesting that NCAM-mediated adhesion promotes formation of cell-to-cell channels. Temperature-sensitive mutant Rous sarcoma virus blocked (reversibly) communication and the subsequent development of neurofilament protein and neurites, but expression of NCAM continued.

Communication compartments in the gastrulating mouse embryo.

We characterized the pattern of gap junctional communication in the 7.5-d mouse embryo (at the primitive streak or gastrulation stage). First we examined the pattern of dye coupling by injecting the fluorescent tracers, Lucifer Yellow or carboxyfluorescein, and monitoring the extent of dye spread. These studies revealed that cells within all three germ layers are well coupled, as the injected dye usually spread rapidly from the site of impalement into the neighboring cells. The dye spread, however, appeared to be restricted at specific regions of the embryo. Further thick section histological analysis revealed little or no dye transfer between germ layers, indicating that each is a separate communication compartment. The pattern of dye movement within the embryonic ectoderm and mesoderm further suggested that cells in each of these germ layers may be subdivided into smaller communication compartments, the most striking of which are a number of "box-like" domains. Such compartments, unlike the restrictions observed between germ layers, are consistently only partially restrictive. In light of these results, we further monitored ionic coupling to determine if some coupling might nevertheless persist between germ layers. For these studies, Lucifer Yellow was coinjected while ionic coupling was monitored. The injected Lucifer Yellow facilitated the identification of the impalement sites, both in the live specimen and in thick sections in the subsequent histological analysis. By using this approach, all three germ layers were shown to be ionically coupled, indicating that gap junctional communication is maintained across the otherwise dye-uncoupled "germ layer compartments." Thus our results demonstrate that partially restrictive communication compartments are associated with the delamination of germ layers in the gastrulating mouse embryo. The spatial distribution of these compartments are consistent with a possible role in the underlying development.
