The Effects of Animations and Multimedia Messages on Public Engagement in Precision Medicine: Assessment of Moderation and Mediation.

Public participation in precision medicine (PM) research is essential to achieving effective health care but has been impeded by a lack of awareness and basic knowledge. There is a critical need for educational materials that can clearly explain PM to foster involvement. This randomized controlled trial with a posttest-only control group design aims to assess the effects of educational messages delivered through animations relative to live-action videos and leaflets on intentions of involvement in PM research. Knowledge as the moderator and four mediators (engagement, vividness, trustworthiness, and cognitive value) of the intended effects were also evaluated. A total of 326 U.S. adults were sampled from Amazon Mechanical Turk. Among participants with less knowledge about PM, animations produced stronger information-seeking intentions and willingness to participate than leaflets. The effects of three message modalities were not significantly different among average and highly knowledgeable participants. Engagement and vividness mediated the effects of animations relative to two other message modalities. Trustworthiness and cognitive value mediated the effects of animations relative to live-action videos. Overall, animations can be an effective communication strategy to motivate involvement in PM but its effectiveness could decline as knowledge increases. The explanations and implications of the findings were discussed.

Clinical characteristics of Australian treatment-naïve patients with classical Hodgkin lymphoma from the lymphoma and related diseases registry.

Comprehensive clinical characteristics of Australian patients with classical Hodgkin Lymphoma (cHL) have not previously been systematically collected and described. We report real-world data of 498 eligible patients from the first 5 years of the Lymphoma and Related Diseases Registry (LaRDR), including baseline characteristics, histologic subtype, and treatment patterns in first-line therapy. Patient demographics and distribution of histopathological subtypes of cHL are similar to reported international cohorts. Doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) was the most common therapy for both early and advanced-stage disease, and 48% of patients with the early-stage disease received radiotherapy. Treatment patterns are consistent with international guidelines. In comorbid patients ≥60 years of age with advanced-stage disease, there is greater variation in treatment. In patients with a recorded response, the objective response rate (ORR) was 96% in early-stage disease, and 88% in advanced-stage disease. Early progression-free survival data suggest Australian patients with cHL have good outcomes, similar to other international studies.

Centre-based comparison of double versus single prevention strategy on transfusion-transmitted cytomegalovirus in at-risk haemopoietic stem cell transplant patients and a state survey on cytomegalovirus-seronegative ordering practises.

BACKGROUND: Universal leucocyte depletion reduces the risk of transfusion-transmitted cytomegalovirus; however, many clinicians still prescribe cytomegalovirus seronegative units. AIM: Our retrospective study aims to confirm the low risk of transfusion-transmitted cytomegalovirus with leucocyte depletion alone and demonstrate the ongoing variability in cytomegalovirus seronegative transfusion prescribing. METHODS: Over a 9-year period (July 2009-July 2018), occurrences of transfusion transmitted cytomegalovirus in cytomegalovirus seronegative donor/recipient haemopoietic stem cell transplant pairs were compared at one allogeneic haemopoietic stem cell transplant centre providing cytomegalovirus seronegative blood products and leucocyte depletion (double prevention) versus another providing leucocyte depletion only (single prevention). Retrospective chart audit identified patient demographics, blood product exposure and cytomegalovirus infection by polymerase chain reaction. A separate audit examined cytomegalovirus seronegative blood product ordering in a broader range of hospital types. RESULTS: We identified 122 and 66 cytomegalovirus-negative donor/recipient haemopoietic stem cell transplant pairs using double and single transfusion prevention strategy respectively. Transfusion exposure to red cells and pooled platelets was similar, although more apheresis platelets were used in the double prevention group. The cytomegalovirus infection rate was 3 (2.4%) and zero in the double and single prevention groups respectively. Cytomegalovirus seronegative unit ordering was not limited to hospitals with obstetric or neonatal populations, suggesting ongoing reliance of cytomegalovirus seronegative units outside this population. CONCLUSIONS: The analysis suggests a double prevention strategy does not provide additional protection against transfusion-transmitted cytomegalovirus. There is ongoing variability in the acceptance of leucocyte depletion alone despite the low risk of cytomegalovirus infection.

Reducing Health Disparities Among African American and Black Caribbean Patients by Improving the Communication Practices of Clinical Research Coordinators.

This manuscript focuses on the communication factors that affect the willingness of African Americans and Black Caribbean patients to participate in clinical trials and research studies. Low rates of research participation by members of communities of color have long been linked to health disparities. While there are many factors that contribute to low rates of accrual of African American and Black patients to clinical trials, a lack of attention to communication factors that enhance or inhibit the recruitment process is central to the problem. In this study, we describe results from the analysis of six focus groups (N = 31) consisting of African American (k = 3) and Black Caribbean (k = 3) participants. Our analyses focus on verbal and nonverbal communication behaviors and how they affect participants' willingness to participate in clinical trials. Specifically, when clinical research coordinators (CRCs) had a professional appearance, made the effort to explain a study in detail, made eye contact, took the time to listen and answer questions patiently, and gave the sense that the CRC was being truthful and transparent, patients felt respected and valued. Additionally, participants emphasized the importance of the process of developing and maintaining a trusting relationship between study participants and CRCs. The results of this study will be used to develop a clinical trial communication training program designed to enhance the communication skills of clinical research coordinators who discuss research participation with African American and Caribbean Black patients.

Community-Based Participatory Research (CBPR) to Enhance Participation of Racial/Ethnic Minorities in Clinical Trials: A 10-Year Systematic Review.

There has not been a significant improvement in the rate of clinical trial accrual in more than 20 years. Worse, the challenge of inadequate representation among racial and ethnic minorities also persists, deepening disparities in health. Community-Based Participatory Research (CBPR) is a participatory communication method that centers on effective dialogue between researchers and community stakeholders with the goal of creating an equitable partnership for health and social change. The objective of the current study was to provide an update since a systematic review in 2012, on the current status of the empirical research, with a particular focus on the elements of CBPR methods used to improve the rate of accrual of members of racial and ethnic minority communities for clinical trials. Our systematic review found a large increase in the number of CBPR related studies and studies related to racial and ethnic representation in research. More than 85% of studies employing CBPR methods saw statistically positive outcomes. Specifically, the elements of CBPR that are associated with these positive outcomes include community partner participation in (1) a study advisory committee, (2) data collection, (3) the development of interventions, and (4) participant recruitment. However, the results of our study indicate that researchers need to be more transparent about the extent of community participation as well as more thoroughly and accurately describe the nature of the partnership with members of minority communities in order to build upon the scientific literature on community-engaged methods.

Tailored Messages About Research Participation: Using an Interactive Information Aid to Improve Study Recruitment.

After a diagnosis of cancer (or other serious disease), patients may be asked to consider joining a clinical trial. Because most people are unfamiliar with the scientific concepts that are necessary to the provision of meaningful informed consent, patient education is necessary. Increasing knowledge alone is not sufficient; understanding how clinical trial participation aligns with personal circumstances and knowledge is central to the decision-making process. In this study, 302 cancer patients and survivors evaluated an interactive information aid (IA) designed to inform their decision to join a research study or clinical trial by providing tailored information to patients' responses to questions pertaining to seven key barriers or facilitators of clinical trial participation. The development of the IA was done with input from the authors' Clinical Translational Science Institute; linked components of the IA were vetted by members and leaders of the institution's NCI-designated comprehensive cancer center. Results of the study indicated that the information aid was successful in significantly reducing fears and increasing knowledge, attitudes, perceived behavioral control, and behavioral intentions about research participation relative to a control condition. Thus, an interactive information aid that provides information that is responsive to patients' values, knowledge, and personal circumstances can help patients to be better prepared to consider a decision about research participation.

Acceptability of a multicomponent, community-based, HPV self-test intervention among Jamaican women.

Jamaican women do not participate in routine Pap test screening as recommended, despite the availability of free Pap test services at community clinics. This low uptake has been associated with cultural and structural barriers such as limited knowledge and awareness, fear of pain associated with Pap tests, fear of diagnosis, modesty or self-consciousness, medical mistrust, and discontent with healthcare services. This study suggests that a multicomponent, community-based intervention that includes education and self-testing for the virus that causes cervical cancer (i.e., Human Papillomavirus, HPV) might increase screening rates. Community outreach workers were hired and recruited 163 women from two low socioeconomic status communities in Kingston, aged 30 to 65 years, and who had not had a Pap test in at least 3 years, to use an HPV self-test kit. Almost all the women (95.6%) used and returned the kit and reported in structured interviews that it was easy to use and preferable to visiting a doctor. Paired samples t-tests revealed that participants perceived higher threat of cervical cancer, greater susceptibility to cancer, greater sense of self-efficacy, and more positive screening social norms at post-test than at pretest. Among returners, 22% had an oncogenic HPV type detected in their sample. Findings demonstrate high acceptability of the HPV self-test among Jamaican women and, therefore, the potential of HPV self-test tools to increase screening uptake. Community-based approaches to disseminate this tool, such as outreach workers and educational small group sessions, appear to be culturally appropriate and effective in this context.

Parent-Child Interaction Therapy with Toddlers: A Community-based Randomized Controlled Trial with Children Aged 14-24 Months.

Objective: Children with early-onset behavioral issues are at high risk for ongoing behavioral, psychological, and social issues.Method: This study examined the efficacy of the first phase of Parent-Child Interaction Therapy with Toddlers, Child-Directed Interaction - Toddler, using a randomized control design. Sixty-six mother-toddler dyads (Child Mage = 19.13 months; 63% male; 34% from a non-English speaking background) referred to a community-based child behavior clinic in Australia received CDI-T immediately or were assigned to a waitlist control condition. At baseline (Time 1) and post-treatment/post-waitlist (Time 2), mothers completed questionnaires (Child Behavior Checklist, Edinburgh Postnatal Depression Scale, Parenting Stress Index - Short Form) and participated in a structured parent-child dyadic play-based interaction later coded using the Dyadic Parent-Child Interaction Coding System and the Emotional Availability Scales.Results: Compared to those who did not receive treatment, mother-child dyads who received the intervention showed significantly better parenting skills (increases in positive parenting skills and decreases in negative parenting skills), emotional availability (increases in parental sensitivity and parental non-intrusiveness), child behavior (decreases in externalizing and internalizing behaviors) and parental perceptions of child difficulty.Conclusions: Results suggest that the CDI-T phase of PCIT-T is a promising intervention for toddlers presenting with behavioral issues. Future studies should be conducted to assess efficacy in other settings and to assess longer-term outcomes.

Evaluating Culturally-targeted Fear Appeal Messages for HPV Self-Sampling among Jamaican Women: A Qualitative Formative Research Study.

Despite the disproportionate burden of cervical cancer among Caribbean women, evaluations of targeted communication interventions to increase screening behaviors are sparsely represented in extant literature. Informed by data on the cognitive, affective and sociocultural factors associated with low cervical screening in the English-speaking island of Jamaica, the current study aimed to explore how theory-based message design, coupled with innovative solutions, might increase screening. In this formative research study, we first described the process used to develop culturally-targeted fear appeal messages embedded within an HPV self-sampling kit developed by the researchers. Then, we shared the results of an evaluation of the kit, which was reviewed by 36 Jamaican women in 8 focus groups, to understand the potential impact of the messages and the utility of HPV self-sampling to increase screening behaviors in this population. The results provide data on effective messages for cervical cancer prevention among Jamaican women, which may be further applicable to underscreened women in the English-speaking Caribbean. Additionally, results from this research suggest support for HPV self-sampling to address salient cultural and structural barriers to screening, which provides an impetus for experimental research in message design to inform policy and practice.

What Motivates You to Share? The Effect of Interactive Tailored Information Aids on Information Sharing about Clinical Trials.

Cancer patients learn about research studies outside of the clinical environment, including websites, print and online advertisements, and interpersonal interactions. When cancer patients share credible information about clinical trials, they also frequently help clarify misunderstandings that may exist in their social networks. The present study investigated how an interactive tailored information aid on clinical trial participation motivated patients' information sharing behaviors. In this study of 312 cancer patients and survivors, an interactive tailored information aid improved patients' likelihood of sharing online and offline information more than a non-interactive tool. Information sharing was directly predicted by cognitive absorption and perceived visual informativeness. In addition, perceived utility and ease of use indirectly impact information sharing positively through the antecedent factors of user engagement and design esthetics. Education level further moderated this effect; information sharing was higher among patients with more education. The implications of these findings are discussed and recommendations for future research are provided.

An Evaluation of Clinical Trial Multimedia to Support Hispanic Cancer Patients' Informational and Decision-Making Needs.

The inclusion of diverse populations in clinical trial research is a social justice imperative. Creating the communicative tools that can support cancer patients across varied cultural backgrounds in processing complex clinical trial information, to achieve informed consent, has been a challenge. This study sought to evaluate specific clinical trial multimedia-a website, four animations, and a decision aid-to meet the decision-making and informational needs of Hispanic patients. The multimedia content was positively evaluated by Hispanic cancer patients. However, the discussions also yielded important steps for culturally adapting these tools to account for particular informational needs and cultural values that would be important to incorporate into these, and future, clinical trial multimedia interventions that target Hispanic populations.

A Meta-analysis of Narrative Game-based Interventions for Promoting Healthy Behaviors.

Health interventions that use serious games have become increasingly popular. However, many of these games have been designed with few immersive game features which would improve users' engagement with the persuasive messages. To address this issue, researchers have incorporated narrative elements in games to facilitate message processing and enhance behavioral change. There have been theoretical debates about whether narratives benefit these interventions; empirical evidences for their effects are slightly mixed. This meta-analysis provides a deeper understanding of the overall impact of narrative game-based interventions on health-related behaviors and their psychological determinants. Combining the results from 22 studies, this meta-analysis found that narrative game-based interventions were effective in changing behaviors, knowledge, self-efficacy, and enjoyment. These effects were moderated by factors such as the genre of the game, the genre of the story, group play, and participant age. Implications of the findings and suggestions for future design of narrative game-based interventions were discussed.

A Comparison of Metaphor Modality and Appeals in the Context of Skin Cancer Prevention.

Health communication experts continually seek out effective strategies to strengthen persuasive campaigns. While there is evidence that verbal metaphors can improve persuasion, little attention has been given to the potential of visual metaphors to enhance health communication effects. To fill this gap, an experiment was conducted to test the effects of metaphor modality (visual vs. verbal) and type of fear appeal used (death-based or appearance-based) on skin protection intentions. Additionally, the moderating role of an individual characteristic (need for cognition), and the mediating role of two processing outcomes (message elaboration and perceived message effectiveness) were examined. Results indicated that there was no significant difference between the main effects of metaphor modality and type of fear appeal, but these message features interacted making the death-based fear appeal the most effective strategy. Need for cognition directly affected perceptions of effectiveness but did not affect skin protection intentions nor message elaboration. Of the two message processing outcomes examined, only perceived message effectiveness mediated the relationship between metaphor modality and skin protection intentions. Theoretical explanations and practical implications are discussed.

Parent-Child Interaction Therapy with Toddlers in a community-based setting: Improvements in parenting behavior, emotional availability, child behavior, and attachment.

Parent-Child Interaction Therapy with Toddlers (PCIT-T) is a new attachment-based parenting intervention designed to meet the needs of children aged 12-24 months presenting with challenging behaviors. This study examined outcomes of the first phase of PCIT-T, Child Directed Interaction-Toddler (CDI-T), 4-months post treatment. Participants were 56 toddlers (Child Mage = 19.13 months) referred to receive CDI-T over an 8-week period at an Australian community-based child behavior treatment clinic for treatment of difficult toddler behaviors. Participants completed questionnaires and observational measures at baseline (Time 1), post-treatment (Time 2), and 4-month follow-up (Time 3). At both Time 2 and Time 3, there were statistically significant increases in observed positive parenting skills and emotional availability and decreases in negative parenting behaviors and child noncompliance. There were also significant improvements in parent-reported child externalizing and internalizing behaviors, parental stress, and maternal depression. There was a pattern of a shift away from attachment insecurity and attachment disorganization. Results suggest that the CDI-T phase of PCIT-T is a promising intervention for toddlers presenting with behavioral issues. Future studies should be conducted to assess efficacy in other settings, using larger samples and utilizing randomized controlled designs.

La terapia de interacción progenitor-niño con niños pequeñitos (PCIT-T) es una nueva intervención de crianza con base en la afectividad y diseñada para cubrir las necesidades de niños de edad de 12 a 24 meses que enfrentan retos de comportamiento. Este estudio examinó los resultados de la primera fase de PCIT-T, Interacción Dirigida del Niño - Niño Pequeñito (CDI-T), 4 meses después del tratamiento. Participaron 56 niños pequeñitos (Edad promedio del niño = 19.13 meses) que habían sido referidos para recibir el CDI-T en un período de 8 semanas en una clínica en Australia con base comunitaria de tratamiento de comportamiento del niño, dedicada al tratamiento de comportamientos difíciles de niños pequeñitos. Los participantes completaron cuestionarios y medidas de observación al momento básico (Primer momento), posteriormente al tratamiento (Segundo momento) y en el seguimiento a los 4 meses (Tercer momento). Tanto en el momento segundo como en el tercero, se dieron mejorías estadísticamente significativas en cuanto a las observadas habilidades positivas de crianza y la disponibilidad emocional y disminuciones en cuanto a las conductas de crianza negativas y la falta de obediencia del niño. También se dieron mejorías significativas en los comportamientos de externalización e internalización del niño según el reporte del progenitor, el estrés de los padres y la depresión materna. Se dio un patrón de alejarse de la inseguridad de la afectividad y la desorganización de la afectividad. Los resultados sugieren que la fase CDI-T del PCIT-T es una intervención prometedora para niños pequeñitos que presentan asuntos de comportamiento. Futuros estudios deben llevarse a cabo para evaluar la efectividad en otros escenarios, usando grupos muestras más grandes y utilizando diseños de control al azar.

La thérapie d'interaction parent-enfant avec un jeune enfant (en anglais Parent-child interaction therapy with Toddlers, soit PCIT-T) est une nouvelle intervention de parentage basée sur l'attachement, conçue afin de remplir les besoins d'enfants âgés de 12 à 24 mois qui présentent des comportements difficiles. Cette étude a examiné les résultats de la première phase de PCIT-T, l'Interaction Dirigée vers l'Enfant - Petit Enfant (Child Directed Interaction - Toddler, soit CDI-T), à 4 mois après le traitement. Les participants ont consisté en 56 jeunes enfants (âgeM de l'Enfant = 19,13 mois) envoyés consulter afin de recevoir une CDI-T sur une période de 8 semaines dans une clinique de traitement du comportement de l'enfant communautaire en Australie, spécialisé dans le traitement de comportements difficiles de jeunes enfants. Les participants ont rempli des questionnaires et des mesures d'observation au niveau de référence (Temps 1), après le traitement (Temps 2) et au suivi de 4 mois (Temps 3). A la fois au Temps 2 et 3 on a noté des augmentations statistiquement significatives dans les compétences positives observées de parentage et la disponibilité émotionnelle ainsi que des baisses dans les comportements négatifs de parentage et le refus d'obéir. On a aussi noté des améliorations importantes dans l'externalisation de l'enfant rapportée par le parent et les comportements d'internalisation, le stress parental et la dépression maternelle. On a observé une tendance se détachant de l'insécurité de l'attachement et de la désorganisation de l'attachement. Les résultats suggèrent que la phases CDI-T de la PCIT-T est une intervention prometteuse pour les jeunes enfants présentant des problèmes de comportement. Des études futures devraient être faites afin d'évaluer l'efficacité d'autres contextes, en utilisant des échantillons plus larges et en utilisant des plans d'étude contrôlées randomisées.

Feasibility and acceptability of internet-delivered parent-child interaction therapy for rural Australian families: a qualitative investigation.

INTRODUCTION: Parent-child interaction therapy (PCIT) is an evidence-based parent management training program for the treatment of childhood disruptive behaviour disorders (DBDs). In Australia, however, due to a lack of services in regional, rural and remote areas, the program is not accessible to all families who might benefit. Preliminary evidence demonstrates that telehealth technologies can be leveraged to deliver PCIT via internet (I-PCIT) to urban families. It is not known, however, to what extent I-PCIT is acceptable and effective for regional and remote families, who are traditionally underserved and face a range of stressors unique to living outside major cities. The present study represents the first qualitative investigation into the experience of I-PCIT for rural or regional Australian families. METHODS: Qualitative interviews were conducted with 10 parents who were living in regional, rural and remote areas of New South Wales (NSW), Australia, and who were referred to an I-PCIT program for treatment of DBD in a child aged 2-4 years. RESULTS: Thematic analysis yielded two pre-treatment themes: motivation for seeking treatment and barriers to previous service access. Three overarching themes were identified in post-treatment interviews: positive outcomes, valuable program components and challenges and acceptability of internet delivery. Results demonstrate that consumers from regional, rural and remote NSW view I-PCIT as an acceptable and effective treatment of childhood DBD, bolstering preliminary evidence about the utility of internet technologies to deliver the high-quality results of PCIT. While internet connection issues were a hindrance to treatment for some participants, all parents reported meaningful positive outcomes for both child and parents. CONCLUSION: The study highlights that I-PCIT effectively expands the reach of mental health services to Australian communities that previously could not access clinic-based parenting services.

Role of bone marrow biopsy for fever of unknown origin in the contemporary Australian context.

BACKGROUND: Bone marrow biopsy (BMB) is an accepted investigation in fever of unknown origin (FUO) to uncover haematological malignancies, such as lymphoma, and sometimes infections. With the advance in imaging modalities, such as 18-fluoro-2-deoxyglucose positron emission tomography (FDG-PET) to identify the focus of lymphoma, BMB may not contribute to the diagnosis when there are no other clinical features to suggest an underlying haematological disease. AIM: To investigate the utility of BMB in determining the cause of FUO, when there are no other indications for BMB. METHODS: Medical records of adult patients who had BMB performed for FUO or febrile illness from 1 January 2005 to 31 December 2014 in four metropolitan tertiary hospitals in Melbourne, Australia were reviewed. Patients with other concurrent indications for BMB, known human immunodeficiency virus infection and previously diagnosed connective tissue diseases were excluded. RESULTS: Seventy-three patients were included in the study. Fifty-one patients had a final diagnosis for fever (systemic inflammatory diseases, infective, malignancy or other) while 22 patients had no diagnoses. In only 10 patients (13.7%) did BMB contribute to the diagnosis, finding either malignancy or granulomata. However, all these diagnoses could have been made without BMB. Two patients with diffuse large B-cell lymphoma had normal BMB. FDG-PET was helpful in making a diagnosis in eight (25%) out of 32 patients. CONCLUSION: Performing BMB in patients with FUO and no other haematological abnormalities is of very limited value, and other investigations, such as FDG-PET, may be more likely to help establish a definitive diagnosis.

Animations about Clinical Trial Participation for Cancer Patients and Survivors.

Communicating about clinical trials and medical research is challenging. An appropriate communication is essential to reduce some of the barriers associated with poor patients' enrollment in clinical trials and with patients' uninformed consent or uninformed refusal. An experiment was conducted to assess the effects of educational animations compared to brochures with and without visuals, and with the materials currently used by the NIH. These materials focused on explaining placebos, randomization, the steps necessary to enroll in a clinical trial, and how and by who patients' protection is ensured. A total of 1194 cancer patients and survivors completed this 4 by 4 experiment through a Qualtrics panel. The findings showed that animations improved participants knowledge about and attitudes toward clinical trials and were more effective than brochures presenting information from the NIH, especially for those individuals with low motivation and low ability to comprehend health-related information. Several evidence-based theoretical explanations of the functioning of animations are provided.

A Content Analysis of the Discussions about Clinical Trials on A Cancer-dedicated Online Forum.

Enrollment rates of cancer clinical trials remain low, affecting the delivery of effective medical treatments. Recent research has documented common factors affecting trial participation, but to improve these efforts more studies are needed to further understand specific concerns and issues of potential participants in multiple contexts. Forums and other online peer-to-peer health communities are crucial to the coping and survivorship of cancer patients. Online health communities will offer valuable information to understand how patients discuss perceptions, motivations, and challenges associated with clinical trial participation, and to understand how patients provide support to each other. The present study conducted a content analysis of 270 posts shared by 154 unique users between August 2017 and January 2018 on a popular online breast cancer forum. The analysis identifies common characteristics of patient users, salient post themes, perceived barriers, emotions, and misconceptions regarding clinical trial participation. The study findings are generally consistent with previous studies but provide in-depth insights into online support between cancer patients about clinical trial participation. Implications for practice and future research are also discussed.

Ready to Make A Decision: A Model of Informational Aids to Improve Informed Participation in Clinical Trial Research.

Enrollment rates for cancer clinical trials remain low, affecting the generalizability of new treatments. Research shows that many patients face significant challenges in understanding basic clinical trial vocabulary and making informed decisions about participation. Informational aids (IA) are developed to address these challenges and support decision making of cancer clinical trial participation. The present study proposed and tested a structural path model to explain the efficacy of three (i.e., interactive, non-interactive, non-cancer control) IAs. The results revealed that clinical trial participation intention was associated with attitudes and social constructs (i.e., social norm, social sharing, and cues to action). Ease of use, rather than knowledge, was the primary communication feature of IA that influenced the outcome variables. The path relations linking messages features, mediators, and outcome variables were different across all three IAs. The results therefore provide theoretical and practical implications for the use and development of IAs to support clinical trial accrual.

Attitudes and Responses of Medical Students and Professional Anatomists to Dissecting Different Regions of the Body.

Although there have been many studies assessing emotional responses of medical students to the dissecting room experience, little is known about whether dissecting particular regions of the human body cause more concern than others. Furthermore, no studies have been conducted on the concerns of professional anatomists. In this study, we assessed the hypothesis that medical students are more concerned about the dissection of the face, the perineum and the extremities of the limbs. We also hypothesized that there are gender differences. For the reactions of a group of professional anatomists from the United States and Europe we hypothesized that they were less concerned than the medical students and showed no differences across the regions of the body. The hypotheses were tested by means of questionnaires distributed to medical students at Cardiff University and at the Descartes Paris University who had recently completed their anatomy courses and to anatomists working at universities in Europe and the USA. Ethical approval for the study was obtained from the ethical committees at the Cardiff School of Biosciences and at Paris and all data was obtained by consent of the respondents and remained confidential. The findings were complex, although the level of concern was low overall. Some regional differences were discerned, particularly concerning the face, the perineum, the hand and the female chest. Anatomists were less concerned than the students and female students and female anatomists showed more concern than their male counterparts. Few differences were discerned however between student respondents who had positive and neutral attitudes to gender "politics" and those who espoused negative views. We recommend that, at the start of an anatomy dissection course, time is spent dealing with sensitive issues (including equality and diversity issues), emotional responses, and matters pertaining to mortality. However, we argue that this should not involve hiding regions of the body, nor overreacting to the natural anxiety of students, since doing either of these things could enhance negative reactions and stifle the progress of the student from being a layperson to a competent healthcare professional.
