Development and evaluation of an interactive CD-ROM refusal skills program to prevent youth substance use: "refuse to use".

An interactive CD-ROM program designed to reduce adolescent substance use was developed and evaluated. The program uses video vignettes to teach refusal skills and socially acceptable responses to substance use situations, specifically offers of marijuana. In a randomized pretest-to-posttest experiment with 74 public school students from six classes in three high schools, significant changes were observed at posttest on (1) the adolescent's personal efficacy to refuse the offer of marijuana, (2) the adolescent's intention to refuse marijuana if offered, and (3) the adolescent's perceptions of the social norms associated with substance use and the importance of respecting another's decision to refuse a drug offer. In addition, adolescents in the treatment condition were able to recall approximately 50% of the portrayed refusal strategies. Findings are discussed with regard to the potential benefits of an interactive multimedia approach for conducting substance use interventions.

Study for verification testing of the helmet-mounted display in the Japanese Experimental Module.

Our purpose is to propose a research and development project in the field of telemedicine. The proposed Multimedia Telemedicine Experiment for Extra-Vehicular Activity will entail experiments designed to support astronaut health management during Extra-Vehicular Activity (EVA). Experiments will have relevant applications to the Japanese Experimental Module (JEM) operated by National Space Development Agency of Japan (NASDA) for the International Space Station (ISS). In essence, this is a proposal for verification testing of the Helmet-Mounted Display (HMD), which enables astronauts to verify their own blood pressures and electrocardiograms, and to view a display of instructions from the ground station and listings of work procedures. Specifically, HMD is a device designed to project images and data inside the astronaut's helmet. We consider this R&D proposal to be one of the most suitable projects under consideration in response to NASDA's open invitation calling for medical experiments to be conducted on JEM.

Maintaining the Characteristics of Effective Clinical Teachers in Computer Assisted Learning Environments.

There has been a growing trend in medical education to integrate the use of computers into the undergraduate medical curriculum. While it seems intuitively obvious that personal computers and the Internet can be useful learning tools, it is not clear that the perceived advantages of Computer Assisted Instruction (CAI) are warranted. One problem is that computers are too often used in CAI simply as presentation devices for predefined material without ample consideration paid to the pedagogical principles that have informed more conventional teaching practices. The creation of an environment that is conducive to effective learning has often been overlooked in favour of the development and use of increasingly more sophisticated technologies. The current paper represents an attempt to delineate ways in which we might better develop instructional multimedia programs by employing some of the strategies believed to characterise effective clinical teaching. To do so, this paper will briefly review the work of Irby and others in an attempt to draw attention to ways in which the characteristics identified by these researchers might be implemented for the use of CAI.

An intelligent tele-healthcare environment offering person-centric and wellness-maintenance services.

Worldwide healthcare delivery trends are undergoing a subtle paradigm shift--patient centered services as opposed to provider centered services and wellness maintenance as opposed to illness management. In this paper we present a Tele-Healthcare project TIDE--Tele-Healthcare Information and Diagnostic Environment. TIDE manifests an 'intelligent' healthcare environment that aims to ensure lifelong coverage of person-specific health maintenance decision-support services--i.e., both wellness maintenance and illness management services--ubiquitously available via the Internet/WWW. Taking on an all-encompassing health maintenance role--spanning from wellness to illness issues--the functionality of TIDE involves the generation and delivery of (a) Personalized, Pro-active, Persistent, Perpetual, and Present wellness maintenance services, and (b) remote diagnostic services for managing noncritical illnesses. Technically, TIDE is an amalgamation of diverse computer technologies--Artificial Intelligence, Internet, Multimedia, Databases, and Medical Informatics--to implement a sophisticated healthcare delivery infostructure.

Salud para su Corazón: a community-based Latino cardiovascular disease prevention and outreach model.

Cardiovascular disease (CVD) is the leading cause of death for Latinos living in the United States. This population is generally unaware of important lifestyle or behavioral changes that can prevent CVD. The National Heart, Lung, and Blood Institute (NHLBI) designed and implemented Salud para su Corazón (Health for Your Heart), a culturally appropriate, community-based, theory-driven intervention model. NHLBI's goals were: (1) to design an intervention model appropriate to Latino populations; (2) to pilot test the model in a specific community with the objectives of increasing awareness about heart disease, raising knowledge about CVD prevention, and promoting heart-healthy lifestyles; and (3) to disseminate the model and the materials developed to other communities with similar needs. An agency-community partnership, under the leadership of the Community Alliance for Heart Health, guided all stages of the community intervention project. The multimedia bilingual community intervention included television telenovela format public service announcements (PSAs), radio programs, brochures, recipe booklets, charlas, a promotores training manual, and motivational videos. An evaluation survey assessed the impact of the intervention. A pre-post intervention survey was conducted with more than 300 participants, and results showed that the respondents were substantially more aware of risk factors for CVD, and had greatly increased their knowledge of ways to prevent heart disease. Dissemination efforts have resulted in numerous requests by health organizations, universities, and health maintenance organizations (HMOs) for educational materials and communication strategies produced by Salud para su Corazón. In addition, Univision, the largest Spanish-language broadcast television network, is airing the initiative's PSAs. Also, training seminars for promotores are being conducted in different regions of the United States, and several locations are planning to replicate this study.

An e-learning caregiving program for prostate cancer patients and family members.

e-health interventions have the potential to augment caregiving training for management of chronic disease. Instruction on caregiving functions often key to patients and families' well being is time consuming but not reimbursable in our current health care system. A theoretically defined interactive multimedia program is described which would assess patient and family member's level of preparedness for specific caregiving functions for prostate cancer and provide tailored skill building vignettes on caregiving techniques. Maximizing today's technology, this program is best designed for a hybrid delivery utilizing both web-based resources and a CD-ROM. Feedback from 45 prostate patients and family members from a Midwest cancer center on perceived needs for caregiving training underscores the potential value of a computer supported intervention for some patients and families. Implementation of the software, marketing, and distribution will be guided in part by recent e-health experiences that leave many health professionals appropriately skeptical about the utility of such products.

Accessing medication information by ethnic minorities: barriers and possible solutions.

AIM: This review discusses two main questions: how suitable is current consumer medication information for minority ethnic groups, and what are effective strategies to overcome existing barriers. The focus is on minority groups whose first language is not the language of the healthcare system. METHOD: We searched electronic databases and printed scientific journals focusing on (ethnic) minorities, health and/or (intercultural) communication. We also asked a discussion group for references. RESULTS: We found only a few articles on intercultural communication on medication or pharmacy information and one article on the improvement of intercultural communication in the pharmacy. Barriers to the access of medication information by ethnic minorities include second language issues and cultural differences due to different health beliefs, together with the low socio-economic status often seen among ethnic minorities. Cultural differences also exist among different socio-economic classes rather than only among ethnic groups. Most often, informal interpreters are used to improve intercultural communication. However, this may result in miscommunication due to a lack of medical knowledge or training on the part of the interpreter. To minimise miscommunication, bilingual health professionals or health interpreters/advocates can be used, although communication problems may still occur. The effectiveness of written information depends on the literacy skills of the target population. Cultural, medical and dialect biases should be avoided by testing the material. Multimedia systems may be alternatives to conventional written information. DISCUSSION: Barriers that ethnic minorities face in accessing medication information and possible solutions involving counselling and additional tools were identified for pharmacy practice. However, more research is needed to develop effective strategies for patient counselling in pharmacy to meet the needs of ethnic minorities.

Development and evaluation of a computer-animated tutor for vocabulary and language learning in children with autism.

Using our theoretical framework of multimodal processing, we developed and evaluated a computer-animated tutor, Baldi, to teach vocabulary and grammar for children with autism. Baldi was implemented in a Language Wizard/Player, which allows easy creation and presentation of a language lesson involving the association of pictures and spoken words. The lesson plan includes both the identification of pictures and the production of spoken words. In Experiment 1, eight children were given initial assessment tests, tutorials, and reassessment tests 30 days following mastery of the vocabulary items. All of the students learned a significant number of new words and grammar. A second within-subject design with six children followed a multiple baseline design and documented that the program was responsible for the learning and generalization of new words. The research indicates that children with autism are capable of learning new language within an automated program centered around a computer-animated agent, multimedia, and active participation and can transfer and use the language in a natural, untrained environment.

Improving the accessibility of an analytic and technical skills MCH toolbox.

OBJECTIVES: To assess our analytic and technical skills website for accessibility and to make necessary corrections. METHODS: We used commercially available software (Jaws and LIFT for Dreamweaver) and an individual with visual impairments to evaluate our self-instructional, analytic, and technical tools. We identified problems in tables, images, multimedia content, PDF files, and links. RESULTS: We repaired the site by using LIFT to make appropriate modifications to the website and tools. CONCLUSIONS: Improving accessibility is advantageous for all Internet users. In addition to responding to legislative mandates, accessible web design creates pages that are often more readable, easier to navigate, and faster to download. Improving the accessibility of websites that incorporate charts and graphs strengthens the ability of all members of the MCH workforce to address the core functions.

Evidence-based decision making and asthma in the internet age: the tools of the trade.

At the dawn of the Information Age, the practice of evidence-based decision making (EBDM) is still hindered by many important barriers related to the decision makers, to the evidence per se or to the health system. Some of these barriers, particularly those related to the distillation, dissemination and packaging of research evidence, could be overcome by recent and ongoing developments in portable/wearable computers, internet appliances, multimedia and wireless broadband internet traffic. This article describes specific EBDM-related tools, with emphasis on internet-enabled "how to" books; and tools to improve the quality of reporting research, to formulate questions; to search for evidence; to access journals, systematic reviews and guidelines; to interact with organizations promoting EBDM; and to tailor evidence to individual cases. However, thinking that all barriers to the practice of EBDM could be solved by fancy information technology is naïve. Barriers related to the generation, interpretation, integration and use of the evidence demand more complex and perhaps unfeasible solutions, as overcoming them will require substantial changes in the structure of the health system, in the politics of science and in the way in which humans think and behave.

An examination of the structure and nomological network of trainee reactions: a closer look at "smile sheets".

Although D. L. Kirkpatrick (1959, 1996) popularized the concept of trainee reactions over 40 years ago, few studies have critically examined trainees' reactions to learning events. In this article, research on mood and emotion is used to develop a theoretical framework for research on trainee reactions. Two studies examine the factor structure of reactions and their nomological network. In Study 1, 178 undergraduate and 101 graduate students listened to a computer-delivered multimedia lecture. Results suggest that (a) reactions can be conceptualized as hierarchical, with overall satisfaction explaining associations among distinct reaction facets (enjoyment, relevance, and technology satisfaction), and (b) reactions are predicted by trainee characteristics. In Study 2, 97 undergraduates experienced the same lecture in 1 of 3 randomly assigned delivery technologies. Reactions were influenced by technology and were related to learning process (engagement) and outcomes (intentions regarding delivery technology, content, and learning). Both studies support the theoretical framework proposed.

Age, ability, and the role of prior knowledge on the acquisition of new domain knowledge: promising results in a real-world learning environment.

Prior knowledge, fluid intelligence (Gf), and crystallized intelligence (Gc) were investigated as predictors of learning new information about cardiovascular disease and xerography with a sample of 199 adults (19 to 68 years). The learning environment included a laboratory multimedia presentation (high-constraint-maximal effort), and a self-directed at-home study component (low-constraint-typical performance). Results indicated that prior knowledge and ability were important predictors of knowledge acquisition for learning. Gc was directly related to learning from the video for both domains. Because the trajectory of Gc stays relatively stable throughout the life span, these findings provide a more optimistic perspective on the relationship between aging and learning than that offered by theories that focus on the role of fluid abilities in learning.

Initial validation of a computer-administered Addiction Severity Index: the ASI-MV.

The Addiction Severity Index--Multimedia Version (ASI-MV) is a CD-ROM-based simulation of the interviewer-administered Addiction Severity Index (ASI). Clients in treatment (N = 202) self-administered the ASI-MV to examine the test-retest reliability, criterion validity, and convergent-discriminant validity of the ASI-MV. Excellent test-retest reliability was observed for composite scores and severity ratings. Criterion validity, tested against the interviewer-administered ASI, was good for the composite scores. For severity ratings, variable agreement was observed between the ASI-MV and each interviewer, suggesting poor interrater reliability among interviewers. This conclusion was bolstered by a finding of superior convergent-discriminant validity for both composite scores and severity ratings compared to the standard ASI. The ASI-MV is a viable alternative to the expensive and potentially unreliable interviewer-administered version.

The case for coherence in scientific explanations: quantitative details can hurt qualitative understanding.

In Experiments 1A and 1B, students read a concise booklet containing 653 words and 6 illustrations describing the formation, propagation, and dispersion of ocean waves (concise group) or an expanded booklet containing 327 additional words and 5 additional illustrations describing relevant mathematical formulas and computations interspersed throughout the lesson (expanded group). In Experiment 2, students viewed a multimedia presentation of narrated animations based on the concise or expanded booklet. In both studies, the expanded group performed more poorly than did the concise group on problem-solving transfer tests. The added quantitative details may have distracted the learner from constructing a qualitative model of the process of ocean waves.

Intranet-based quality improvement documentation at the Veterans Affairs Maryland Health Care System.

The Pathology and Laboratory Medicine Service of the Veterans Affairs Maryland Health Care System is inspected biannually by the College of American Pathologists (CAP). As of the year 2000, all documentation in the Anatomic Pathology Section is available to all staff through the VA Intranet. Signed, supporting paper documents are on file in the office of the department chair. For the year 2000 CAP inspection, inspectors conducted their document review by use of these Web-based documents, in which each CAP question had a hyperlink to the corresponding section of the procedure manual. Thus inspectors were able to locate the documents relevant to each question quickly and efficiently. The procedure manuals consist of 87 procedures for surgical pathology, 52 procedures for cytopathology, and 25 procedures for autopsy pathology. Each CAP question requiring documentation had from one to three hyperlinks to the corresponding section of the procedure manual. Intranet documentation allows for easier sharing among decentralized institutions and for centralized updates of the laboratory documentation. These documents can be upgraded to allow for multimedia presentations, including text search for key words, hyperlinks to other documents, and images, audio, and video. Use of Web-based documents can improve the efficiency of the inspection process.

Understanding the phase-change mechanism of rewritable optical media.

Present-day multimedia strongly rely on rewritable phase-change optical memories. We demonstrate that, different from the current consensus, Ge(2)Sb(2)Te(5), the material of choice in DVD-RAM, does not possess the rocksalt structure but more likely consists of well-defined rigid building blocks that are randomly oriented in space consistent with cubic symmetry. Laser-induced amorphization results in drastic shortening of covalent bonds and a decrease in the mean-square relative displacement, demonstrating a substantial increase in the degree of short-range ordering, in sharp contrast to the amorphization of typical covalently bonded solids. This novel order-disorder transition is due to an umbrella-flip of Ge atoms from an octahedral position into a tetrahedral position without rupture of strong covalent bonds. It is this unique two-state nature of the transformation that ensures fast DVD performance and repeatable switching over ten million cycles.
