Abstract: Amyotrophic lateral sclerosis (ALS) is a progressively debilitating neurodegenerative condition that occurs in adulthood and targets the motor neurons. Social support is crucial to the well-being and quality of life of people with unpredictable and incurable diseases such as ALS. Members of the PatientsLikeMe (PLM) ALS online support community share social support but also exchange and build distributed knowledge within their discussion forum. This qualitative analysis of 1,000 posts from the PLM ALS online discussion examines the social support within the PLM ALS online community and explores ways community members share and build knowledge. The analysis responds to 3 research questions: RQ1: How and why is knowledge shared among the distributed participants in the PLM-ALS threaded discussion forum?; RQ2: How do the participants in the PLM-ALS threaded discussion forum work together to discover knowledge about treatments and to keep knowledge discovered over time?; and RQ3: How do participants in the PLM-ALS forum co-create and treat authoritative knowledge from multiple sources including the medical literature, healthcare professionals, lived experiences of patients and "other" sources of information such as lay literature and alternative health providers? The findings have implications for supporting knowledge sharing and discovery in addition to social support for patients.
2Cortese, J. ; Lustria, M.L.A.: Can tailoring increase elaboration of health messages delivered via an adaptive educational site on adolescent sexual health and decision making?.
In: Journal of the American Society for Information Science and Technology. 63(2012) no.8, S.1567-1580.
Abstract: Tailoring, the development of health messages based on assessment of key psychosocial variables that influence a prescribed behavior, has been gaining ground as an effective health education approach. The efficacy of this approach is based on the assumption that increasing personal relevance motivates greater elaboration, which is an important precondition for persuasion. Little research has been conducted to tease out the direct effects of tailoring on message processing. This study examines the effects of a tailored health education site on participants' evaluations of and elaboration on health messages. A total of 151 teens were randomly assigned to explore a tailored Web site or a nontailored Web site on adolescent sexual health and decision making. Results of the experiment indicated a statistically significant main effect for condition (tailoring) after controlling for situational motivation and need for cognition, F(1, 148) = 4.467, MSS = 2.177, p < .05, partial ?2 = .030. Further evaluations and implications for future research are discussed.

Abstract: While advances in highly targeted therapies and increased use of mammogram services have contributed to the overall decline of breast cancer deaths in the United States, these benefits have not been distributed equitably. Less educated, poor, rural, non-Hispanic African American women have poorer access to cancer services and are less likely to have had a mammogram than are urban women. Lack of physician recommendations and perceived barriers in accessing diagnostic services are major factors that hinder the uptake of regular mammograms in rural communities. This article reports results of formative research conducted as part of a larger study focused on the participatory development of an electronic reminder system for breast cancer screening. The article discusses insights gained from focus groups with rural patients and clinicians about their information needs, breast cancer screening behaviors, barriers to care, and mammography referral practices.
4Lustria, M.L.A.: Can interactivity make a difference? : Effects of interactivity on the comprehension of and attitudes toward online health content.
In: Journal of the American Society for Information Science and Technology. 58(2007) no.6, S.766-776.
Abstract: The Internet is increasingly being recognized for its potential for health communication and education. The perceived relative advantage of the Internet over other media is its cost-effectiveness and interactivity, which in turn contribute to its persuasive capabilities. Ironically, despite its potential, we are nowhere nearer understanding how interactivity affects processing of health information and its contribution in terms of health outcomes. An experiment was conducted to examine the effects of Web interactivity on comprehension of and attitudes towards two health Web sites, and whether individual differences might moderate such effects. Two sites on skin cancer were designed with different levels of interactivity and randomly assigned to 441 undergraduate students (aged 18-26) at a large southeastern university. The findings suggest that interactivity can significantly affect comprehension as well as attitudes towards health Web sites. The article also discusses insights into the role of interactivity on online health communications, and presents implications for the effective design of online health content.
