本研究探討深思的可能性模型（Elaboration Likelihood Model）在設計推廣使用營養標籤的廣告中的適用性。香港的一所中學的169位學生參與了一個2 x 2 x 3（健康意識：高vs. 低 x 論據：數據 vs. 經驗 x 代言人：專家vs. 名人 vs. 普通人）的實驗。 部分假設得到支持。 健康意識的主效果明顯。 具有較高健康意識的青少年更易被廣告說服。 健康意識和代言人具有交叉效應。對於健康意識較高的人來說，營養師更有說服力， 而對於健康意識較低的人來說，名人更有影響力。論據和代言人的搭配影響了資訊的處理路徑。如果以數據為主的論據是由普通人提供的，則更易推動青少年使用營養標籤。而如果以個人經驗為主的論據是由名人提供的，則更有效。統計結果將在深思的可能性模型下得以展開討論。 本文還會對開展針對青少年的公共健康傳播運動提出建議。 / This study tested the utility of the Elaboration Likelihood Model in creating effective Public Service Announcements (PSAs) of nutrition label use. Students (N=169) from a secondary school in Hong Kong participated in a 2x2x3 (Health consciousness: High vs. Low x Argument: Informational vs. Testimonial x Source: Expert vs. Celebrity vs. Ordinary Person) factorial design experiment. Hypotheses were partially supported. Main effect was located for health consciousness. Adolescents with high health consciousness were more persuaded by the PSAs. There was an interaction effect between health consciousness and source. A dietitian as the source was most persuasive to people with high health consciousness, while low health conscious people were most influenced by a celebrity. The information processing route was biased by the match of argument and source. Informative argument made by an ordinary person was more likely to motivate adolescents to use nutrition label, while testimonial argument made by a celebrity was the most effective. The findings are discussed in light of ELM and match-up hypotheses. Recommendations are also offered for public health communication campaigns. / Detailed summary in vernacular field only. / Dong, Zhuowen. / Thesis (M.Phil.)--Chinese University of Hong Kong, 2013. / Includes bibliographical references (leaves 72-84). / Abstracts also in Chinese; appendixes in Chinese. / Abstract --- p.i / Acknowledgements --- p.iii / Table of Content --- p.vi / Chapter Chapter 1: --- Introduction --- p.1 / Publicity Campaign of Nutrition Labelling Scheme in Hong Kong --- p.1 / Adolescent and Nutrition Label (NL) --- p.3 / Significance of the Research --- p.4 / Organization of Thesis --- p.7 / Chapter Chapter 2: --- Literature Review --- p.9 / Adolescents and Preventive Health Behavior --- p.9 / Health Consciousness --- p.10 / Information Processing of Adolescents --- p.12 / Informative or Testimonial Argument --- p.13 / Expert vs. Celebrity vs. Ordinary person --- p.15 / Source credibility --- p.20 / Initial attitude --- p.24 / Self-efficacy --- p.25 / Chapter Chapter 3: --- Theoretical Framework --- p.28 / The Elaboration Likelihood Model of Persuasion --- p.28 / Chapter Chapter 4: --- Research questions and Hypothesis --- p.34 / Chapter Chapter 5: --- Methodology --- p.39 / Subjects and Design --- p.40 / Procedure --- p.40 / Materials and Manipulations --- p.41 / Independent variables --- p.44 / Dependent variables --- p.46 / Chapter Chapter 6: --- Results --- p.49 / Health Consciousness Assessment --- p.49 / General results --- p.49 / Covariate --- p.56 / Predictors of Behavioral Intention --- p.56 / Hypothesis Testing and Answers to Research Questions --- p.57 / Chapter Chapter 7: --- Discussion --- p.59 / Chapter Chapter 8: --- Implication --- p.66 / Chapter Chapter 9: --- Limitation and Direction for Future research --- p.69 / References --- p.72 / Lists of Appendices / Chapter Appendix A --- :Experiment Questionnaire --- p.85 / Chapter Appendix B --- :Experiment Masterial--- PSA --- p.87 / Chapter Appendix C --- :Experiment Masterial--- PSA --- p.88 / Chapter Appendix D --- :Experiment Masterial--- PSA --- p.89 / Chapter Appendix E --- :Experiment Masterial--- PSA --- p.90 / Chapter Appendix F --- :Experiment Masterial--- PSA --- p.91 / Chapter Appendix G --- :A Proposed PSA of Nutrition Labels --- p.92

The purpose of this study was 1) to examine the significance of a patient’s active or passive role in terms of his/her health management; 2) to determine if a relationship exists between one’s active and passive scores and his/her self-directed learning readiness, and 3) to identify if his/her view of one’s self as a patient (when diagnosed with a chronic disease) impacted his/her own personal health management. Utilizing the quantitative analysis of The Self-Directed Learning Readiness Scale and the Vanderbilt Pain Management Inventory, 81 individuals’ descriptive statistics were analyzed. Self-directed learning was found to positively influence an individual’s ability to be an active patient. The moderated demographic characteristics of age, ethnicity, education level, and gender did not have a direct relationship between selfdirected learning readiness and active/passive coping groups. Further, it was established that the majority of the participants within the study, 83.75%, considered themselves an active patient managing their lupus diagnosis. However, 16.25% of the participants did not believe that they were actively managing their illness. Self-directed learning characteristics were examined through the responses to an open-ended question. The two most prevalent themes pertained to active coping and control. Characteristics of self-directed learning readiness appeared predominant amongst the responses, particularly goal-orientation and accepting responsibility for learning. Minimal themes regarding planning and enjoying learning were provided within the data. These characteristics were identified throughout the study in hopes of further research and program implementations that will help to develop leadership abilities and activity levels of self-health management in chronically ill patients. This will enable lupus patients to have a more positive outcome, it will help them successfully manage their own health, and it will improve their overall quality of life. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2016. / FAU Electronic Theses and Dissertations Collection

Use of the Internet can increase patients' understanding about their medical conditions and offers opportunities to strengthen the patient-physician relationship, increase patient satisfaction, and improve health outcomes. However, physicians vary widely in the extent to which they accept patient online medical information seeking and make it part of the patient-physician relationship. This paper explores factors impacting the extent to which physicians advocate (encourage, speak in favor, or are supportive of) patient internet use. Specifically, using social cognitive theory as a theoretical base, this study develops a model of the determinants of physician advocation of patient use of the internet for information about medical conditions and treatments. Survey data collected from a random sample of 179 physicians licensed to practice medicine in Florida is used to test the proposed model. Proxy efficacy for patient internet use, social efficacy for enlisting patient internet use, performance outcomes expectations, and personal outcome expectations are shown to be significant determinants of physician professional advocation of patient internet use. In addition to its direct impact, proxy efficacy is shown to influence intention to advocate patient internet use indirectly thru social efficacy and outcome expectations, demonstrating the key role of this construct in the proxy agency model. Self-efficacy, in contrast, is not found to be a significant factor. Overall, the results support the proposed model of technology use. / by Neil Morton. / Thesis (Ph.D.)--Florida Atlantic University, 2009. / Includes bibliography. / Electronic reproduction.

Effective communication is essential for both a satisfying and productive patient-provider relationship. Ineffective communication can lead to many detrimental patient outcomes including a lack of access to care, an inability to navigate the healthcare environment, a decreased adherence to treatment recommendations, and a lack of patient understanding about disease risk factors, prevention, and management. The Healthy People 2010 initiative recognized the importance of communication by including several health communication-related goals in its objectives. A goal of one of these objectives included increasing the percentage of patients who reported that their care providers have satisfactory communication skills. Researchers can gain insight about those barriers that prevent providers from experiencing effective communication by examining the patients' perspectives about communication. The primary aim of this pilot study was to explore urban African American women's perspectives about the communication utilized during clinical encounters with providers via the use of semi-structured interviews. The semi-structured interviews collected data about a variety of topics including participants' breast cancer-related knowledge, attitudes, beliefs, and practices. Data was also collected about participants' clinical encounter experiences, including their comprehension of health information and their communication experiences with medical providers and other types of health care professionals. Any responses that discussed participants' communication experiences with providers, comprehension of health information, or perspectives about factors that could impede or facilitate communication were selected for analysis. In addition to the semi-structured interviews, participants also completed two health literacy assessments in order to gauge their health literacy levels. Women were administered the Rapid Estimate of Adult Literacy in Medicine (REALM), a word recognition assessment, and the Short Test of Functional Health Literacy in Adults (STOFHLA), a comprehension assessment. Eligibility criteria included women who: (1) were aged 50 and older, (2) were English-speaking, (3) able to respond to interview questions without assistance, (4) of African descent, (5) were Harlem residents, and (6) had never received a diagnosis of breast cancer. One hundred women participated in the study. Data about the effectiveness of providers' communication skills, patients' abilities to comprehend health information, patients' communication experiences with various types of health care providers, and preferred sources of health information were collected from the interviews. Open-ended questions were utilized to gather information about factors that women deemed as either impediments or facilitators to effective communication with providers. Collected data from interviews were analyzed qualitatively. In addition to information about participants' health literacy scores from the literacy assessments, final results included demographic information, preferred sources of health information, and information about those factors that women viewed as either impediments or facilitators to effective communication with doctors and with other health care providers both in and outside of the medical appointment. Additionally, findings from the qualitative analysis results were utilized in order to inform the creation of health communication recommendations for providers who treat urban African American female patients.

Communication is a critical aspect of clinical work. In 2010, the Joint Commission (JC) found that gaps in communication were among leading factors contributing to medical errors. Healthcare processes, such as patient discharge, depend on interdisciplinary communication to be successful. Electronic health records (EHRs) have the potential to facilitate communication and information sharing between interdisciplinary care team members; however, challenges remain in designing tools for team-based care and questions remain in understanding how EHRs impact interdisciplinary team communication. This dissertation focuses on understanding how EHRs can be designed to support communication and information sharing within interdisciplinary patient care teams. The first aim of the dissertation investigated how EHRs impact interdisciplinary clinical teams’ communication, shared mental models, and information sharing activities. The results showed that implementing new EHR tools appeared to have little impact on communication and shared mental models, but new information sharing activities mediated by EHR developed. These changes and lack thereof suggest that new EHR tools will be specifically needed to facilitate interdisciplinary team information sharing activities. The second aim of the dissertation investigates the information sharing activities and information needs of interdisciplinary team members during patient discharge. The results showed that the information clinicians sought out during discharge depended on the roles that person played as well as the progress of the discharge process. Future EHR tools should be aware of how patient care teams are progressing through the patient discharge process in order to provide information contextualized to their current tasks. In conclusion, interdisciplinary team communication and information sharing remain poorly supported by current EHRs and new tools designed specifically for interdisciplinary teams should provide information based on the completion of team activities.

Introduction - Eighty five per cent of Australians visit a GP each year, but do not receive all of the preventive care which is indicated for them. There have been no controlled trials of the effects of on-screen preventive care reminders in Australian general practice, and there is little published research examining characteristics of patients, doctors and consultations associated with the performance of preventive services in general practice. This study aimed to measure the effects of opportunistic reminders and to explore previously unexamined patient, GP and consultation factors associated with performance of preventive activities. The hypotheses were : a ) that general practitioners who were using a computer medical record system would take at least fifteen per cent more of opportunities to perform preventive care activities if they were reminded ; b ) that this would occur without any significant increase in the number of consultations or in patient billings ; and c ) that every characteristic of patients, GPs, consultations and preventive opportunities would be significantly associated with the performance of the preventive activities. Method - All patients who attended a ten GP fully computerised practice during one year were enrolled and randomised either to an intervention group, for whom the GPs received opportunistic on-screen reminders about eleven preventive activities, or to a 'usual care' control group. Performance by the GPs of the preventive activities was recorded automatically and correlated with routinely-collected demographic and clinical information about the patients and billing data. Results - For the intervention group compared to the control group, the GPs took thirty two per cent more of the preventive opportunities without any increase in numbers of services or in patient billings. Every characteristic of patients, GPs, consultations and preventive opportunities was independently associated with the performance of at least two of the preventive activities. Discussion - This trial has shown that a low cost minimally-intrusive intervention in the form of automated opportunistic reminder messages can significantly improve GPs' performance of preventive care activities. The findings of this trial may help to improve the design and effectiveness of opportunistic reminders in clinical software, and provide direction about possible changes to the health system which may foster increased provision of preventive care. / Thesis (Ph.D.)--University of Adelaide, School of Population Health and Clinical Practice, Discipline of General Practice, 2006.
