Use of visual aids in general practice consultations: A questionnaire-based survey

Objectives

Visual aids (VAs) seem effective to improve doctor-patient communication. The objective was to describe how VAs are used in consultation and what French general practitioners (GPs) expect of them.

Methods

Cross-sectional study using a self-administered questionnaire among French GPs in 2019. Descriptive and multinominal logistic regression analyses were performed.

Results

Of the 376 respondents, 70% used VAs at least weekly and 34% daily; 94% considered VAs useful/very useful; 77% felt they did not use VAs enough. Sketches were the most used VAs and considered the most useful. Younger age was significantly associated with a higher rate of use of simple digital images. VAs were mainly used to describe anatomy and facilitate patient comprehension. Main reasons for not using VAs more often were time spent searching, lack of habit and poor quality of available VAs. Many GPs requested a database of good quality VAs.

Conclusions

GPs use VAs regularly in consultations but would like to use them more often. Informing GPs of the usefulness of VAs, training them to draw adapted sketches and creating a good quality databank are some possible strategies to increase the use of VAs.

Innovation

This study described in detail the use of VAs as tool for doctor-patient communication.

Effects of a clinical decision support system and patient portal for preventing medication-related falls in older fallers: Protocol of a cluster randomized controlled trial with embedded process and economic evaluations (ADFICE_IT)

BACKGROUND

Falls are the leading cause of injury-related mortality and hospitalization among adults aged ≥ 65 years. An important modifiable fall-risk factor is use of fall-risk increasing drugs (FRIDs). However, deprescribing is not always attempted or performed successfully. The ADFICE_IT trial evaluates the combined use of a clinical decision support system (CDSS) and a patient portal for optimizing the deprescribing of FRIDs in older fallers. The intervention aims to optimize and enhance shared decision making (SDM) and consequently prevent injurious falls and reduce healthcare-related costs.

METHODS

A multicenter, cluster-randomized controlled trial with process evaluation will be conducted among hospitals in the Netherlands. We aim to include 856 individuals aged ≥ 65 years that visit the falls clinic due to a fall. The intervention comprises the combined use of a CDSS and a patient portal. The CDSS provides guideline-based advice with regard to deprescribing and an individual fall-risk estimation, as calculated by an embedded prediction model. The patient portal provides educational information and a summary of the patient's consultation. Hospitals in the control arm will provide care-as-usual. Fall-calendars will be used for measuring the time to first injurious fall (primary outcome) and secondary fall outcomes during one year. Other measurements will be conducted at baseline, 3, 6, and 12 months and include quality of life, cost-effectiveness, feasibility, and shared decision-making measures. Data will be analyzed according to the intention-to-treat principle. Difference in time to injurious fall between the intervention and control group will be analyzed using multilevel Cox regression.

DISCUSSION

The findings of this study will add valuable insights about how digital health informatics tools that target physicians and older adults can optimize deprescribing and support SDM. We expect the CDSS and patient portal to aid in deprescribing of FRIDs, resulting in a reduction in falls and related injuries.

Prevalence and Characteristics of Pictures in Cancer Screening Information: Content Analysis of UK Print Decision Support Materials

This paper answers calls for further theoretical work into types of pictures used in health information. Pictures influence message reception, interpretation, and retention, making this an important area for research in health communication. A content analysis was used to produce a systematic and theory-orientated assessment of the use of pictures in cancer screening information materials (N = 44) produced for invitees to either cervical, breast or bowel screening in the United Kingdom. The main categories investigated in this study were function, content and style of the pictures. Pictures used in cancer screening information materials were twice as likely to be used to demonstrate what something looked like or depict a situation (display pictures) than to convey a specific cancer screening message (message pictures). The messages being conveyed were predominantly related to screening procedures (51%) or outcomes (38%) rather than screening experiences (6%) or decisions (9%). Pictures were rarely used to portray a narrative in the materials (n = 12). The paper brings conceptual clarity to the ways pictures can be, and have so far been used, to communicate cancer screening information. This study identifies that pictures conveying a cancer-related message, and pictures in the format of a narrative, should be used more often in print cancer screening communications.

Information Architects: Using Community-Engaged and Qualitative Methods to Design a Technology-Based Nutrition and Cancer Risk Intervention for Rural Adults

BACKGROUND

Nearly half of all cancer deaths are preventable through modification or avoidance of key risk factors. As such, there is a growing urgency to identify effective, low-resource, and scalable technologies that support clinical care and patient self-management of health behaviors.

PURPOSE

Informed by theories of cognitive load and user-centered design approaches, we develop a culturally tailored, multicomponent digital intervention to engage rural adults between 50-73 years old with their personalized nutrition risk factors for colorectal cancer (CRC) prevention.

METHOD

A total of 48 adults tested a Virtual Health Assistant (VHA) prototype during focus groups in individual think-aloud interviews to facilitate iterative adaptations to a web-based CRC prevention intervention. Qualitative data was analyzed to identify user needs and preferences related to information and with a focus on avoiding cognitive overload.

RESULTS

The VHA serves as a conceptual pre-training for users helping them understand CRC prevention key concepts and engendering motivation to act on the promoted behavior. A website was identified as a strategy to fill information gaps and present actionable information, after the VHA interaction. Cognitive load reducing strategies were used including segmenting where information is presented in learner-controlled segments rather than continuously.

CONCLUSIONS

Findings indicate potential benefits of designing CRC prevention information technologies with the rural older adults. Integrating patient-centered needs before launching health information web content will be important as the rapid growth of telemedicine aims to reach traditionally marginalized and underserved populations. Theoretically informed considerations for potential adverse outcomes (eg, information overload) are discussed.

The Web-Based Advance Care Planning Program "Explore Your Preferences for Treatment and Care": Development, Pilot Study, and Before-and-After Evaluation

BACKGROUND

Web-based advance care planning (ACP) programs may support patients in thinking about and discussing their preferences for future treatment and care. However, they are not widely available, and only a limited number of programs are evidence based.

OBJECTIVE

We aimed to develop and evaluate an evidence-based, interactive web-based ACP program that guides users through the process of thinking about, discussing, and recording of preferences for treatment and care.

METHODS

The program "Explore your preferences for treatment and care" was developed, pilot-tested on feasibility, and subsequently evaluated; engagement in ACP was assessed before program completion and 2 months after program completion using the ACP Engagement Survey (score 1-5) among 147 persons with chronic disease. Usability (score 0-100) and user satisfaction (score 1-5) were also assessed.

RESULTS

ACP engagement increased from 2.8 before program completion to 3.0 two months after program completion (P<.001); contemplation about ACP increased from 2.6 to 2.8 (P=.003), and readiness for ACP increased from 2.2 to 2.5 (P<.001). No changes were found for knowledge about ACP (3.0-3.2; P=.07) and self-efficacy for ACP (3.8-3.8; P=.25). The program was perceived as usable (mean 70, SD 13), attractive (mean 3.8, SD 0.7), and comprehensible (mean 4.2, SD 0.6).

CONCLUSIONS

We developed an evidence-based, interactive web-based ACP program in cocreation with patients, relatives, and health care professionals. Before-and-after evaluation showed that the program can support people in taking first steps in ACP and in reflecting on preferences for treatment and care, by guiding them through the process of ACP using a stepwise approach. Participants perceived the program as usable and understandable, and they were satisfied with the program and with the amount of information. Health care professionals may use the program as a tool to start ACP discussions with their patients. The program may increase awareness of ACP.

Show me the roads and give me a road map: Development of a patient conversation tool to improve lung cancer treatment decision-making

Objective

Evidence-based decision support resources do not exist for persons with lung cancer. We sought to develop and refine a treatment decision support, or conversation tool, to improve shared decision-making (SDM).

Methods

We conducted a multi-site study among patients with stage I-IV non-small cell lung cancer (NSCLC) who completed or had ongoing lung cancer treatment using semi-structured, cognitive qualitative interviews to assess participant understanding of content. We used an integrated approach of deductive and inductive thematic analysis.

Results

Twenty-seven patients with NSCLC participated. Participants with prior cancer experiences or those with family members with prior cancer experiences reported better preparedness for cancer treatment decision-making. All participants agreed the conversation tool would be helpful to clarify their thinking about values, comparisons, and goals of treatment, and to help patients communicate more effectively with their clinicians.

Conclusion

Participants reported that the tool may empower them with confidence and agency to actively participate in cancer treatment SDM. The conversation tool was acceptable, comprehensible, and usable. Next steps will test effectiveness on patient-centered and decisional outcomes.

Innovation

A personalized conversation tool using consequence tables and core SDM components is novel in that it can encourage a tailored, conversational dynamic and includes patient-centered values along with traditional decisional outcomes.

Trauma-Informed Radiation Therapy: Implementation and Evaluation of a Sensitive Practice Tool for Female Patients Undergoing Radiotherapy for Breast Cancer

PURPOSE

For childhood sexual abuse survivors, cancer care can be retraumatizing because of perceived similarities to the original sexual violence. The authors' group designed and implemented a sensitive practice tool (SPT) and evaluated the feasibility of the tool in female patients receiving breast radiation.

METHODS

The SPT was offered as a "universal precaution" to patients with breast cancer as part of standard clinical care. Patients were given the SPT, which included an instructional video about radiotherapy and a survey about triggers and preferences. The survey results were provided to radiation therapists and used to personalize patients' care. A retrospective chart review and quality improvement survey of therapists were performed.

RESULTS

Of 739 eligible patients, 493 (66.7%) completed the SPT from November 2013 to June 2019. Among respondents, 281 (57.0%) reported potential triggers, 395 (80.1%) reported distress management preferences, and 59 (12.0%) requested psychosocial referrals. Mean patient satisfaction was high, and a majority of patients were likely to recommend the SPT to other patients (85.3%). Among radiation therapists (n = 13), 100% reported that the SPT made it easier to customize or individualize patient care. Trauma disclosure was not significantly associated with increased frequency of trigger endorsement (P = .07) but was associated with increased endorsement of distress management preferences (P = .02) and psychosocial referral requests (P < .001).

CONCLUSIONS

The reported experience with the SPT in the breast radiotherapy setting demonstrated that potential triggers and distress management preferences among patients are common and that patient satisfaction with the SPT is high, yielding clinically meaningful and actionable sensitive practice information.

The Patient Navigator: Can a systematically developed online health information tool improve patient participation and outcomes related to the consultation in older patients newly diagnosed with colorectal cancer?

BACKGROUND

Older cancer patients may search for health information online to prepare for their consultations. However, seeking information online can have negative effects, for instance increased anxiety due to finding incorrect or unclear information. In addition, existing online cancer information is not necessarily adapted to the needs of older patients, even though cancer is a disease often found in older individuals.

OBJECTIVE

The aim of this study was to systematically develop, implement and evaluate an online health information tool for older cancer patients, the Patient Navigator, providing information that complements the consultation with healthcare providers.

METHOD

For the development and evaluation of the Patient Navigator, the four phases of the MRC framework were used. In the first and second phase the Patient Navigator was developed and pilot tested based on previous research and sub-studies. During the third phase the Patient Navigator was implemented in four Dutch hospitals. In the last phase, a pilot RCT was conducted to evaluate the Patient Navigator in terms of usage (observational tracking data), user experience (self-reported satisfaction, involvement, cognitive load, active control, perceived relevance of the tool), patient participation (observational data during consultation), and patient outcomes related to the consultation (questionnaire data regarding anxiety, satisfaction, and information recall). Recently diagnosed colorectal cancer patients (N = 45) were randomly assigned to the control condition (usual care) or the experimental condition (usual care + Patient Navigator).

RESULTS

The Patient Navigator was well used and evaluated positively. Patients who received the Patient Navigator contributed less during the consultation by using less words than patients in the control condition and experienced less anxiety two days after the consultation than patients in the control condition.

CONCLUSION

Since the Patient Navigator was evaluated positively and decreased anxiety after the consultation, this tool is potentially a valuable addition to the consultation for patients. Usage of the Patient Navigator resulted in patients using less words during consultations, without impairing patients' satisfaction, possibly because information needs might be fulfilled by usage of the Patient Navigator. This could create the possibility to personalize communication during consultations and respond to other patient needs.

Development and Pilot-Testing of a Patient Decision-Making Aid for Nutrition in Age-Related Macular Degeneration

OBJECTIVE

We described the development and pilot-testing of an application based patient decision-making aid (PDA) for nutrition in age-related macular degeneration (AMD). Alpha-testing and beta-testing were performed to explore the PDA's usability, acceptability, and comprehensibility in the design stage and in "real-life" conditions.

METHODS

A nutrition PDA was developed in this study by a multidisciplinary steering committee that consisted of ophthalmologists, nurses, nutritionists, and methodologists using a systematic development process. The PDA was based on a smartphone native installation and a free-to-use app. First, based on information from literature reviews and focus group interviews for needs assessment, we developed a decision aid prototype. Second, we conducted the alpha testing to explore the acceptability, usability, and comprehensibility of the PDA prototype among 18 AMD patients. Third, a before/after study was conducted to assess changes in the attitudes, risk perceptions, intentions, knowledge, decisional conflicts, and decision self-efficacy of 33 AMD patients.

RESULTS

The alpha test proved that the nutrition PDA is acceptable and usable. In the beta test, after the AMD participants used the PDA, their scores for knowledge [mean = 13.3, standard deviation (SD) = 2.92], attitude (mean = 18.97, SD = 2.19), decision self-efficacy (mean = 23.94, SD = 6.04), and preparation significantly increased (mean = 26.30, SD = 4.90), and their score for decisional conflict significantly decreased (mean = 10.15, SD = 3.66). There was no significant difference in anxiety (mean = 2.64, SD = 1.08) before and after the use of the PDA. The mean score in the system usability scale was above 70 (mean = 72.61; SD = 5.38), which indicates the good usability of the PDA. With regard to the PDA acceptability, the scores for satisfaction with its comprehensibility, satisfaction with its attractiveness, and satisfaction with its emotional support were 5.49 (SD = 1.03), 5.30 (SD = 1.40), and 4.91(SD = 1.07), respectively, which show its adequate acceptability.

CONCLUSION

Our study showed that the nutrition PDA was an acceptable and suitable instrument for AMD patients and fit the values of all its stakeholders. This study is an important step in supporting shared decision-making, which has the potential to provide a more patient-centered and value-based nutrition health system for individuals with different types of AMD.

Testing the effects on information use by older versus younger women of modality and narration style in a hospital report card

Background

Hospital report cards (HRCs) are usually presented in a textual and factual format, likely hampering information processing.

Objective

This study aimed to investigate the effects of audiovisual and narrative information in HRCs on user responses, and to test differences between older and younger women.

Design

A 2 (modality [textual vs. audiovisual]) × 3 (narration style [factual vs. process narrative vs. experience narrative]) online experiment was conducted. Information about breast cancer care was used as a case example. Age (younger [<65] vs. older [≥65]) was included as a potential effect modifier.

Setting and Participants

A total of 631 disease‐naïve women (M_age = 56.06) completed an online survey. The outcomes were perceived cognitive load, satisfaction, comprehension, information recall and decisional conflict. Data were analysed using AN(C)OVAs.

Results

Audiovisual (vs. textual) information resulted in higher information satisfaction across age groups, but was associated with lower comprehension in older women. An experience narrative (vs. factual information) increased satisfaction with attractiveness and emotional support of the information only in older women. A three‐way interaction effect was found, suggesting that older women were most satisfied with the comprehensibility of audiovisual factual or textual process narrative information. Younger women were most satisfied with the comprehensibility of audiovisual process narrative or textual factual information.

Discussion and Conclusion

Audiovisual and narrative information in an HRC showed beneficial effects on satisfaction measures. In particular, audiovisual information could be incorporated into HRCs to increase satisfaction with information.

Public Contribution

Lay persons helped in optimizing the visuals used in the stimulus materials by checking for clarity.

Building on Evidence to Improve eHealth Literacy in Older Adults: A Systematic Review

This review aimed to provide information on ways to improve eHealth literacy in older adults by assessing current studies examining eHealth literacy. To achieve the aim, this review focused on what theories or theoretical frameworks were used in the studies, what factors were related to eHealth literacy, and what outcome variables were used in eHealth literacy interventions for older adults. Five electronic databases were searched to identify eligible studies. The Cochrane Handbook for Systematic Reviews of Interventions was followed to select relevant studies, and narrative synthesis was performed. Among a total of 27 studies, 13 described theories or theoretical frameworks. Credibility in Internet health information, knowledge, and experience were identified as modifiable factors related to eHealth literacy. The most frequently used outcome variable was eHealth literacy efficacy. Nurses who are interested in improving eHealth literacy in older adults should consider appropriate theoretical frameworks and multiple factors influencing eHealth literacy.

Effects of Information Architecture on the Effectiveness and User Experience of Web-Based Patient Education in Middle-Aged and Older Adults: Online Randomized Experiment

Background

Web-based patient education is increasingly offered to improve patients’ ability to learn, remember, and apply health information. Efficient organization, display, and structural design, that is, information architecture (IA), can support patients’ ability to independently use web-based patient education. However, the role of IA in the context of web-based patient education has not been examined systematically.

Objective

To support intervention designers in making informed choices that enhance patients’ learning, this paper describes a randomized experiment on the effects of IA on the effectiveness, use, and user experience of a patient education website and examines the theoretical mechanisms that explain these effects.

Methods

Middle-aged and older adults with self-reported hip or knee joint complaints were recruited to use and evaluate 1 of 3 patient education websites containing information on total joint replacement surgery. Each website contained the same textual content based on an existing leaflet but differed in the employed IA design (tunnel, hierarchical, or matrix design). Participants rated the websites on satisfaction, engagement, control, relevance, trust, and novelty and completed an objective knowledge test. Analyses of variance and structural equation modeling were used to examine the effects of IA and construct a theoretical model.

Results

We included 215 participants in our analysis. IA did not affect knowledge gain (P=.36) or overall satisfaction (P=.07) directly. However, tunnel (mean 3.22, SD 0.67) and matrix (mean 3.17, SD 0.69) architectures were found to provide more emotional support compared with hierarchical architectures (mean 2.86, SD 0.60; P=.002). Furthermore, increased perceptions of personal relevance in the tunnel IA (β=.18) were found to improve satisfaction (β=.17) indirectly. Increased perceptions of active control in the matrix IA (β=.11) also improved satisfaction (β=.27) indirectly. The final model of the IA effects explained 74.3% of the variance in satisfaction and 6.8% of the variance in knowledge and achieved excellent fit (χ²_17,215=14.7; P=.62; root mean square error of approximation=0.000; 95% CI [0.000-0.053]; comparative fit index=1.00; standardized root mean square residual=0.044).

Conclusions

IA has small but notable effects on users’ experiences with web-based health education interventions. Web-based patient education designers can employ tunnel IA designs to guide users through sequentially ordered content or matrix IA to offer users more control over navigation. Both improve user satisfaction by increasing user perceptions of relevance (tunnel) and active control (matrix). Although additional research is needed, hierarchical IA designs are currently not recommended, as hierarchical content is perceived as less supportive, engaging, and relevant, which may diminish the use and, in turn, the effect of the educational intervention.

Preference for and understanding of graphs presenting health risk information. The role of age, health literacy, numeracy and graph literacy

OBJECTIVE

To investigate 1) younger (< 65) and older (> 65) adults' preference for and understanding of graph formats presenting risk information, and 2) the contribution of age, health literacy, numeracy and graph literacy in understanding information.

MATERIALS AND METHODS

To assess preferences, participants (n = 219 < 65 and n = 227>65) were exposed to a storyboard presenting six types of graphs. Understanding (verbatim and gist knowledge) was assessed in an experiment using a 6 (graphs: clock, bar, sparkplug, table, pie vs pictograph) by 2 (age: younger [<65] vs older [>65]) between-subjects design.

RESULTS

Most participants preferred clock, pie or bar chart. Pie was not well understood by both younger and older people, and clock not by older people. Bar was fairly well understood in both groups. Table yielded high knowledge scores, particularly in the older group. Lower age, higher numeracy and higher graph literacy contributed to higher verbatim knowledge scores. Higher health literacy and graph literacy were associated with higher gist knowledge.

DISCUSSION AND CONCLUSION

Although not the preferred format, tables are best understood by older adults.

PRACTICE IMPLICATIONS

Graph literacy skills are essential for both verbatim and gist understanding, and are important to take into account when developing risk information.

Differences in Memory, Perceptions, and Preferences of Multimedia Consumer Medication Information: Experimental Performance and Self-Report Study

Background

Electronic health resources are becoming prevalent. However, consumer medication information (CMI) is still predominantly text based. Incorporating multimedia into CMI (eg, images, narration) may improve consumers’ memory of the information as well as their perceptions and preferences of these materials.

Objective

This study examined whether adding images and narration to CMI impacted patients’ (1) memory, (2) perceptions of comprehensibility, utility, or design quality, and (3) overall preferences.

Methods

We presented 36 participants with CMI in 3 formats: (1) text, (2) text + images, and (3) narration + images, and subsequently asked them to recall information. After seeing all 3 CMI formats, participants rated the formats in terms of comprehensibility, utility, and design quality, and ranked them from most to least favorite.

Results

Interestingly, no significant differences in memory were observed (F_2,70=0.1, P=0.901). Thus, this study did not find evidence to support multimedia or modality principles in the context of CMI. Despite the absence of effects on memory, the CMI format significantly impacted perceptions of the materials. Specifically, participants rated the text + images format highest in terms of comprehensibility (χ²₂=26.5, P<.001) and design quality (χ²₂=35.69, P<.001). Although the omnibus test suggested a difference in utility ratings as well (χ²₂=8.21, P=.016), no significant differences were found after correcting for multiple comparisons. Consistent with perception findings, the preference ranks yielded a significant difference (χ²₂=26.00, P<.001), whereby participants preferred the text + images format overall. Indeed, 75% (27/36) of participants chose the text + images format as their most favorite. Thus, although there were no objective memory differences between the formats, we observed subjective differences in comprehensibility, design quality, and overall preferences.

Conclusions

This study revealed that although multimedia did not appear to influence memory of CMI, it did impact participants’ opinions about the materials. The lack of observed differences in memory may have been due to ceiling effects, memory rather than understanding as an index of learning, the fragmented nature of the information in CMI itself, or the size or characteristics of the sample (ie, young, educated subjects with adequate health literacy skills). The differences in the subjective (ie, perceptions and preferences) and objective (ie, memory) results highlight the value of using both types of measures. Moreover, findings from this study could be used to inform future research on how CMI could be designed to better suit the preferences of consumers and potentially increase the likelihood that CMI is used. Additional research is warranted to explore whether multimedia impacts memory of CMI under different conditions (eg, older participants, subjects with lower levels of health literacy, more difficult stimuli, or extended time for decay).

Patients' Evaluation of a Preparatory Online Communication Tool for Older Patients With Cancer Preceding Chemotherapy

BACKGROUND

The online tool PatientVOICE has been developed to enhance older patients' participation during educational nursing encounters preceding chemotherapy and to increase their information recall.

OBJECTIVE

The aim of this study was to evaluate perceived usefulness, usability, satisfaction with emotional support, language use, attractiveness, and visit intention of PatientVOICE by older (ex-)patients with cancer.

METHODS

Older (ex-)patients with cancer were invited to evaluate the website via an online questionnaire. Perceived usefulness, usability, and satisfaction with emotional support were measured using evaluation statements, the System Usability Scale, and an adapted subscale of the Website Satisfaction Scale, respectively. Questions were also included about language use and attractiveness of the website and patients' intention to visit the website.

RESULTS

A total of 44 questionnaires were analyzed. Many patients evaluated the provided information and other integrated techniques (such as the question prompt sheet, video fragments, and the audio facility) positively on aspects as usefulness and helpfulness. The usability was considered good (mean scale score, 74.3). Most patients (84.9%) considered the language use on the website clear, and 63.6% of the patients found the website attractive. Many patients (71.9%) would visit the website if they would like to gather information on the encounter preceding chemotherapy, and 62.5% of the patients would do this for information about chemotherapy.

CONCLUSIONS

PatientVOICE is evaluated as a useful and user-friendly tool, enabling patients to prepare themselves for the nursing encounter preceding chemotherapy and to gather information about chemotherapy.

IMPLICATIONS FOR PRACTICE

Preparatory online tools, such as PatientVOICE, can be implemented in hospitals to offer patients extra support.

Testing the Effects of Modality and Narration Style on Patients' Information Use in a Lung Cancer Treatment Decision Aid

Background

Risk information in patient decision aids (PDAs) is often difficult for older patients to process. Providing audiovisual and narrative information may enhance the understanding and use of health-related information. We studied the effects on patients’ information processing and use of audiovisual and narrative information of an early-stage non–small-cell lung cancer treatment decision aid explaining surgery and stereotactic ablative radiotherapy. We further investigated differences between older and younger patients.

Methods

We conducted a 2 (modality: textual v. audiovisual) × 2 (narration style: factual v. narrative) online experiment among cancer patients and survivors (N = 305; M_age = 62.42, SD = 11.68 y). Age was included as a potential modifier: younger (<65 y) versus older (≥65 y) age. We assessed 1) perceived cognitive load, 2) satisfaction with information, 3) comprehension, 4) information recall, and 5) decisional conflict. Analysis of variance was used for data analysis.

Results

Irrespective of patient age, audiovisual information (compared with textual information) led to lower perceived cognitive load, higher satisfaction with information, and lower decisional conflict (subscale Effective Decision). Narrative information (compared with factual information) led to reduced decisional conflict (subscale Uncertainty) but only in younger patients. Combining audiovisual information with factual information also resulted in lower perceived cognitive load in younger patients as compared with older patients.

Limitations

Patients who actually face the decision, especially older patients, might be more motivated to process our decision-aid information than the present study participants who responded to a hypothetical situation online.

Conclusions

Providing participants with audiovisual information, irrespective of their age, improved their processing and use of information in a decision aid. Narratives did not clearly benefit information processing.

Adapting Online Patient Decision Aids: Effects of Modality and Narration Style on Patients' Satisfaction, Information Recall and Informed Decision Making

Audiovisual and narrative information are often used in online decision aids. However, few studies have tested whether these strategies are more effective compared to other types of information. We tested the effect of these strategies on satisfaction with the information, recall and informed decision-making in a 2 (Modality: audiovisual vs. textual) x 2 (Narration style: narrative vs. factual) experimental design. Data was collected in an online experiment among 262 analogue cancer patients. Since most cancer patients are older people, we also assessed if the effectiveness of these strategies differs depending on the patient's age. Data was analyzed using Structural Equation Modeling. Findings showed audiovisual modality had a positive effect on satisfaction. Moreover, audiovisual modality improved recall, both directly and indirectly via satisfaction, which subsequently resulted in better-informed decision-making. Narratives resulted in more satisfaction, but not better recall or informed decision-making. These effects were found in patients of all ages.

Evaluation Tools for Assistive Technologies: A Scoping Review

OBJECTIVE

Assistive technologies (ATs) support independence and well-being in people with cognitive, perceptual, and physical limitations. Given the increasing availability and diversity of ATs, evaluating the usefulness of current and emerging ATs is crucial for informed comparison. We aimed to chart the landscape and development of AT evaluation tools (ETs; ATETs) across disparate fields in order to improve the process of AT evaluation and development.

DATA SOURCES

We performed a scoping review of ATETs through database searching of MEDLINE, Embase, CINAHL, HaPI, PsycINFO, Cochrane Reviews, and Compendex as well as citation mining.

STUDY SELECTION

Articles explicitly referencing ATETs were retained for screening. We included ETs if they were designed to specifically evaluate ATs.

DATA EXTRACTION

We extracted 5 attributes of ATETs: AT category, construct evaluated, conceptual frameworks, type of end user input used for ATET development, and presence of validity testing.

DATA SYNTHESIS

From screening 23,434 records, we included 159 ATETs. Specificity of tools ranged from single to general ATs across 40 AT categories. Satisfaction, functional performance, and usage were the most common constructs of 103 identified. We identified 34 conceptual frameworks across 53 ETs. Finally, 36% incorporated end user input and 80% showed validation testing.

CONCLUSIONS

We characterized a wide range of AT categories with diverse approaches to their evaluation based on varied conceptual frameworks. Combining these frameworks in future ATETs may provide more holistic views of AT usefulness. ATET selection may be improved with guidelines for conceptually reconciling results of disparate ATETs. Future ATET development may benefit from more integrated approaches to end user engagement.

Provider caring and structuring treatment information to improve cancer patients' recall: Does it help?

OBJECTIVES

Patient recall of medical information is usually poor. Healthcare providers can employ affect-oriented (i.e., showing care) or cognition-oriented communication styles (i.e., structuring information) to enhance recall, but research evidence is limited especially among clinical and/or older patient populations. This video-vignette study manipulated provider caring and information structuring to examine effects on recall and trust among cancer patients/survivors.

METHODS

In an online survey, 148 participants (M_age = 62) were randomized to one of four video conditions in a two (standard communication vs. enhanced caring) by two (standard vs. enhanced structuring) design, and completed measures of active recall, recognition, and trust.

RESULTS

Increased caring or structuring did not enhance active recall or recognition, instead both were higher among younger, female, or highly educated participants. The caring condition induced higher perceived trust in the provider within the whole sample, but trust was significantly correlated with decreased recall (r = -.268) among younger participants.

CONCLUSIONS

Provider caring can strengthen the patient-provider relationship by enhancing trust. Yet, increased trust may impair recall among younger patients. Structuring treatment information did not enhance recall and recognition, but additional research is needed.

PRACTICE IMPLICATIONS

Providers may use additional ways of structuring/organizing information to help enhance recall (e.g., written information).

Realizing better doctor-patient dialogue about choices in palliative care and early phase clinical trial participation: towards an online value clarification tool (OnVaCT)

BACKGROUND

Patients with advanced cancer for whom standard systemic treatment is no longer available may be offered participation in early phase clinical trials. In the decision making process, both medical-technical information and patient values and preferences are important. Since patients report decisional conflict after deciding on participation in these trials, improving the decision making process is essential. We aim to develop and evaluate an Online Value Clarification Tool (OnVaCT) to assist patients in clarifying their values around this end-of-life decision. This improved sharing of values is hypothesized to support medical oncologists in tailoring their information to individual patients' needs and, consequently, to support patients in taking decisions in line with their values and reduce decisional conflict.

METHODS

In the first part, patients' values and preferences and medical oncologists' views hereupon will be explored in interviews and focus groups to build a first prototype OnVaCT using digital communication (serious gaming). Next, we will test feasibility during think aloud sessions, to deliver a ready-to-implement OnVaCT. In the second part, the OnVaCT, with accompanied training module, will be evaluated in a pre-test (12-18 months before implementation) post-test (12-18 months after implementation) study in three major Dutch cancer centres. We will include 276 patients (> 18 years) with advanced cancer for whom standard systemic therapy is no longer available, and who are referred for participation in early phase clinical trials. The first consultation will be recorded to analyse patient-physician communication regarding the discussion of patients' values and the decision making process. Three weeks afterwards, decisional conflict will be measured.

DISCUSSION

This project aims to support the discussion of patient values when considering participation in early phase clinical trials. By including patients before their first appointment with the medical oncologist and recording that consultation, we are able to link decisional conflict to the decision making process, e.g. the communication during consultation. The study faces challenges such as timely including patients within the short period between referral and first consultation. Furthermore, with new treatments being developed rapidly, molecular stratification may affect the patient populations included in the pre-test and post-test periods.

Development and pilot-testing of a colorectal cancer screening decision aid for individuals with varying health literacy levels

OBJECTIVE

Making an informed decision about colorectal cancer screening requires health literacy. Our aim was to develop and pilot-test a computer-based decision aid to support informed decision making about whether or not to participate in colorectal cancer screening for individuals with varying health literacy levels in the Netherlands.

METHODS

First, we designed and adapted the decision aid prototype among 25 individuals with low (n = 15) and adequate (n = 10) health literacy. Second, we used a before/after study to assess changes in knowledge, attitude, intention, decisional conflict, deliberation, anxiety and risk perception in an online survey among 81 individuals eligible for colorectal cancer screening with low (n = 35) and adequate (n = 46) health literacy.

RESULTS

The decision aid was acceptable, comprehensible, reduced decisional conflict, increased deliberation and improved knowledge about colorectal cancer screening, but not about colorectal cancer, among individuals with adequate and low health literacy. Usability was slightly higher for participants with adequate health literacy compared to those with low health literacy.

CONCLUSION

The decision aid is promising in supporting informed decision making about colorectal cancer screening, also among individuals with lower health literacy.

PRACTICE IMPLICATIONS

Further refinement of interactive features, such as videos, animations and the values clarification exercise, is needed to increase the usability of the decision aid.

Tailored Web-Based Information for Younger and Older Patients with Cancer: Randomized Controlled Trial of a Preparatory Educational Intervention on Patient Outcomes

Background

Many patients with cancer, including older patients (aged ≥65 years), consult the Web to prepare for their doctor’s visit. In particular, older patients have varying needs regarding the mode in which information is presented (eg, via textual, visual, or audiovisual modes) owing to age-related sensory (eg, impaired vision and hearing) and cognitive decline (eg, reduced processing speed). Therefore, Web-based information targeted at older patient populations is likely to be used and processed more effectively, and evaluated more positively, when tailored to age-related capabilities and preferences. This, in turn, may benefit patient outcomes.

Objective

This randomized controlled trial tested the effects of a Web-based tailored educational intervention among newly diagnosed younger (<65 years) and older (≥65 years) patients with cancer. We compared the intervention group who viewed a mode-tailored website (ie, enabling patients to tailor information using textual, visual, and audiovisual modes) with 3 control groups view a nontailored website (ie, text only, text with images, and text with videos). We examined website experience outcomes (ie, website satisfaction, website involvement, knowledge, anxiety, and communication self-efficacy) and consultation experience outcomes (ie, question asking during consultation, anxiety, and information recall).

Methods

Patients from a multidisciplinary outpatient clinic (N=232) viewed a mode-tailored or nontailored website as preparation before their hospital consultations to discuss diagnosis and treatment. Data were collected before (T1), during (T2), and after (T3) visitation. Website experience outcomes were assessed with questionnaires (T1). Patients’ question asking was coded from videotaped consultations, and anxiety was assessed through a questionnaire (T2). Telephone interviews were conducted to assess knowledge acquired from the website before (T1) and after consultation (T3), and information recall from the consultation (T3).

Results

The preparatory website was well used across all conditions (mean 34 min). Younger patients viewing the mode-tailored website were more satisfied before consultation (P=.02) and reported lower anxiety after consultation (P=.046; vs text only). This pattern was not found in older patients. Mode tailoring yielded no other significant differences in patient outcomes. Regression analyses showed that website involvement (beta=.15; P=.03) and, to a lesser extent, website satisfaction (beta=.15; P=.05) positively associated with knowledge before consultation (T1). In turn, higher knowledge before consultation (beta=.39; P<.001), together with time on the website (beta=.21; P=.002; T1), predicted information recall from consultations (T3). Patients with higher knowledge before consultation (T1) also reported higher knowledge from the website afterward (T3; beta=.22; P=.003).

Conclusions

Offering preparatory online information before consultations benefits information processing and patient outcomes of both younger and older newly diagnosed patients with cancer. Younger patients benefit even more when information is offered in a mode-tailored manner. We discuss the theoretical, methodological, and practical implications for patient-provider communication research in an electronic health era.

Development and validation of a patient decision aid for prostate Cancer therapy: from paternalistic towards participative shared decision making

BACKGROUND

Patient decision aids (PDAs) can support the treatment decision making process and empower patients to take a proactive role in their treatment pathway while using a shared decision-making (SDM) approach making participatory medicine possible. The aim of this study was to develop a PDA for prostate cancer that is accurate and user-friendly.

METHODS

We followed a user-centered design process consisting of five rounds of semi-structured interviews and usability surveys with topics such as informational/decisional needs of users and requirements for PDAs. Our user-base consisted of 8 urologists, 4 radiation oncologists, 2 oncology nurses, 8 general practitioners, 19 former prostate cancer patients, 4 usability experts and 11 healthy volunteers.

RESULTS

Informational needs for patients centered on three key factors: treatment experience, post-treatment quality of life, and the impact of side effects. Patients and clinicians valued a PDA that presents balanced information on these factors through simple understandable language and visual aids. Usability questionnaires revealed that patients were more satisfied overall with the PDA than clinicians; however, both groups had concerns that the PDA might lengthen consultation times (42 and 41%, respectively). The PDA is accessible on http://beslissamen.nl/ .

CONCLUSIONS

User-centered design provided valuable insights into PDA requirements but challenges in integrating diverse perspectives as clinicians focus on clinical outcomes while patients also consider quality of life. Nevertheless, it is crucial to involve a broad base of clinical users in order to better understand the decision-making process and to develop a PDA that is accurate, usable, and acceptable.

Impact of Personal Trust Tendency on Patient Compliance Based on Internet Health Information Seeking

Background: Personal trust tendency is an individual characteristic that can affect one's evaluation of others, behavior and its related outcomes. It may significantly affect one's health information seeking behavior and compliance. Therefore, this article aims at figuring out how personal trust tendency influences patient compliance through the internet health information seeking and patient satisfaction with it. Methods: Data were collected from 336 valid participants through an online survey in China. There are two independent variables: (1) cognition-based trust tendency and (2) affect-based trust tendency, three intervening variables (emerging internet health information seeking, conservative internet health information seeking, and satisfaction with internet health information), one dependent variable (patient compliance), and control variables. We performed confirmative factor analysis and structural equation modeling to test the hypotheses. Results: The cognition- and affect-based trust tendency positively affects patient compliance through the mediation of emerging and conservative internet health information seeking and satisfaction with internet health information. Surprisingly, strong positive relationships between affect-based trust tendency and emerging and conservative internet health information seeking were found, which are contrary to our initial hypothesis. Conclusions: Health information is considerably important when regarding health-related issues for individuals with cognition- and affect-based trust tendency. Physicians should encourage patients to seek health information on the internet and guide them to use internet health information that suits them. Information exchange and correlations should be involved in doctor-patient interactions. By following the suggestions just cited, better patient compliance can likely be obtained.

Optimising eHealth tools for older patients: Collaborative redesign of a hospital website

Most hospital websites have not been developed in collaboration with patients and, therefore, rarely take into account the preferences and abilities of older patients. This study describes the systematic redesign of an existing hospital website in a co‐design process with patients and professional stakeholders (e.g. researchers, physicians, nurses, department heads, policymakers, website designers), with the aim to make it more user‐friendly for older patients with colorectal cancer (CRC). The redesign process consisted of three phases, where (I) both existing content and design were evaluated among CRC patients; (II) a prototype website was developed based on these insights; which (III) was evaluated again before making final adjustments. Mixed research methods were used for the redesign process. Specifically, insights from existing literature, outcomes from qualitative and quantitative empirical studies conducted by our team, and expert knowledge from relevant stakeholders, were collected and discussed in multidisciplinary consensus meetings, and served as input for the redesigned website. While the existing website was evaluated poorly, the qualitative evaluation of the prototype website in phase 3 showed that the newly redesigned website was usable for older CRC patients. A practical roadmap on how to collaboratively redesign and optimise existing eHealth tools to make them suitable for and operational in clinical settings is provided.

How Tailoring the Mode of Information Presentation Influences Younger and Older Adults' Satisfaction with Health Websites

Although older adults are increasingly using online health information, many websites are not senior-friendly, which might lead to user-problems and dissatisfaction among older people. It has been suggested that websites targeted at older adults should take into account age-related abilities and limitations, for example by providing the opportunity to adjust the modality (i.e., "mode") of information presentation based on visual and auditory capabilities. This study investigates the effects of a mode-tailored website, allowing users to self-tailor the mode of information presentation, on younger and older adults' satisfaction with health websites. The results from a 5 (condition: tailored vs. text, text with visuals, text with audiovisual, combination) × 2 (age: younger [25-45] vs. older [≥ 65] adults) experimental study (N = 563) show that mode tailoring positively influenced satisfaction with the attractiveness and comprehensibility of the website, as compared to non-tailored conditions. These effects on website satisfaction were not different for younger and older adults. The current study provides relevant insights for researchers and practitioners in the field of digital health communication.

Older Patients' Recall of Online Cancer Information: Do Ability and Motivation Matter More than Chronological Age?

This study proposes and tests a model to provide a more comprehensive understanding of the contribution of chronological age versus age-related ability and motivation factors in explaining recall of online cancer information among older patients (n = 197). Results revealed that recall is not a matter of chronological age per se, but rather a matter of ability and motivation. Age-related ability and motivation factors explained 37.9% of the variance in recall. Health literacy, involvement with the webpage, and satisfaction with the emotional support were positively associated with recall. Furthermore, recall was negatively related to frailty, anger, future time perspective, and perceived cognitive load. The findings pose relevant opportunities for tailoring interventions to improve online information provision for older cancer patients.

Effect of Message Format and Content on Attitude Accessibility Regarding Sexually Transmitted Infections

Sexually transmitted infections (STIs) are widespread in the United States among people ages 15-24 years and cost almost $16 billion yearly. It is therefore important to understand message design strategies that could help reduce these numbers. Guided by exemplification theory and the extended parallel process model (EPPM), this study examines the influence of message format and the presence versus absence of a graphic image on recipients' accessibility of STI attitudes regarding safe sex. Results of the experiment indicate a significant effect from testimonial messages on increased attitude accessibility regarding STIs compared to statistical messages. Results also indicate a conditional indirect effect of testimonial messages on STI attitude accessibility, though threat is greater when a graphic image is included. Implications and directions for future research are discussed.

Health Literacy and Online Health Information Processing: Unraveling the Underlying Mechanisms

The usefulness of the Internet as a health information source largely depends on the receiver's health literacy. This study investigates the mechanisms through which health literacy affects information recall and website attitudes. Using 2 independent surveys addressing different Dutch health websites (N = 423 and N = 395), we tested the mediating role of cognitive load, imagination ease, and website involvement. The results showed that the influence of health literacy on information recall and website attitudes was mediated by cognitive load and imagination ease but only marginally by website involvement. Thus, to improve recall and attitudes among people with lower health literacy, online health communication should consist of information that is not cognitively demanding and that is easy to imagine.

Decision aids to help older people make health decisions: a systematic review and meta-analysis

BACKGROUND

Decision aids have been overall successful in improving the quality of health decision making. However, it is unclear whether the impact of the results of using decision aids also apply to older people (aged 65+). We sought to systematically review randomized controlled trials (RCTs) and clinical controlled trials (CCTs) evaluating the efficacy of decision aids as compared to usual care or alternative intervention(s) for older adults facing treatment, screening or care decisions.

METHODS

A systematic search of (1) a Cochrane review of decision aids and (2) MEDLINE, Embase, PsycINFO, Cochrane library central registry of studies and Cinahl. We included published RCTs/CCTs of interventions designed to improve shared decision making (SDM) by older adults (aged 65+) and RCTs/CCTs that analysed the effect of the intervention in a subgroup with a mean age of 65+. Based on the International Patient Decision aid Standards (IPDAS), the primary outcomes were attributes of the decision and the decision process. Other behavioral, health, and health system effects were considered as secondary outcomes. If data could be pooled, a meta-analysis was conducted. Data for which meta-analysis was not possible were synthesized qualitatively.

RESULTS

The search strategy yielded 11,034 references. After abstract and full text screening, 22 papers were included. Decision aids performed better than control resp. usual care interventions by increasing knowledge and accurate risk perception in older people (decision attributes). With regard to decision process attributes, decision aids resulted in lower decisional conflict and more patient participation.

CONCLUSIONS

This review shows promising results on the effectiveness of decision aids for older adults. Decision aids improve older adults' knowledge, increase their risk perception, decrease decisional conflict and seem to enhance participation in SDM. It must however be noted that the body of literature on the effectiveness of decision aids for older adults is still in its infancy. Only one decision aid was specifically developed for older adults, and the mean age in most studies was between 65 and 70, indicating that the oldest-old were not included. Future research should expand on the design, application and evaluation of decision aids for older, more vulnerable adults.

How Are Online Health Messages Processed? Using Eye Tracking to Predict Recall of Information in Younger and Older Adults

Little research has focused on what precedes the processing of health messages to predict recall of information and whether age matters in this regard. To address this gap, this study investigates the relationship between attention and recall among younger (<65 years) and older (≥65 years) adults. Using eye tracking, we exposed participants to a webpage consisting of text-only information, text with cognitive illustrations, or text with affective illustrations. When attention to text increased, older adults recalled more information, whereas younger adults did not. However, younger adults paid more attention to cognitive illustrations than older adults and recalled more information. These results reveal conditions under which health messages are effectively recalled by younger and older adults.

Online Health Information Tool Effectiveness for Older Patients: A Systematic Review of the Literature

Online health information tools (OHITs) have been found to be effective in improving health outcomes. However, the effectiveness of these tools for older patients has been far from clear. This systematic literature review therefore provides an overview of online health information tool effectiveness for older patients using a two-dimensional framework of OHIT functions (i.e., providing information, enhancing information exchange, and promoting self-management) and outcomes (i.e., immediate, intermediate, and long-term outcomes). Comprehensive searches of the PubMed, EMBASE, and PsycINFO databases are conducted to identify eligible studies. Articles describing outcomes of patient-directed OHITs in which a mean sample or subgroup of age ≥65 years was used are included in the literature review. A best evidence synthesis analysis provides evidence that OHITs improve self-efficacy, blood pressure, hemoglobin levels, and cholesterol levels. Limited evidence is found in support of OHIT effects on knowledge, perceived social support, health service utilization, glycemic control, self-care adherence, exercise performance, endurance, and quality of life. OHITs seem promising tools to facilitate immediate, intermediate, and long-term outcomes in older patients by providing information, enhancing information exchange, and promoting self-management. However, future studies should evaluate the effectiveness of OHITs for older patients to achieve stronger levels of evidence.

The effect of modality and narration style on recall of online health information: results from a Web-based experiment

Background

Older adults are increasingly using the Internet for health information; however, they are often not able to correctly recall Web-based information (eHealth information). Recall of information is crucial for optimal health outcomes, such as adequate disease management and adherence to medical regimes. Combining effective message strategies may help to improve recall of eHealth information among older adults. Presenting information in an audiovisual format using conversational narration style is expected to optimize recall of information compared to other combinations of modality and narration style.

Objective

The aim of this paper is to investigate the effect of modality and narration style on recall of health information, and whether there are differences between younger and older adults.

Methods

We conducted a Web-based experiment using a 2 (modality: written vs audiovisual information) by 2 (narration style: formal vs conversational style) between-subjects design (N=440). Age was assessed in the questionnaire and included as a factor: younger (<65 years) versus older (≥65 years) age. Participants were randomly assigned to one of four experimental webpages where information about lung cancer treatment was presented. A Web-based questionnaire assessed recall of eHealth information.

Results

Audiovisual modality (vs written modality) was found to increase recall of information in both younger and older adults (P=.04). Although conversational narration style (vs formal narration style) did not increase recall of information (P=.17), a synergistic effect between modality and narration style was revealed: combining audiovisual information with conversational style outperformed combining written information with formal style (P=.01), as well as written information with conversational style (P=.045). This finding suggests that conversational style especially increases recall of information when presented audiovisually. This combination of modality and narration style improved recall of information among both younger and older adults.

Conclusions

We conclude that combining audiovisual information with conversational style is the best way to present eHealth information to younger and older adults. Even though older adults did not proportionally recall more when audiovisual information was combined with conversational style than younger adults, this study reveals interesting implications for improving eHealth information that is effective for both younger and older adults.

Illustrations enhance older colorectal cancer patients' website satisfaction and recall of online cancer information

This study aims to investigate the effects of illustrations in online cancer information on older cancer patients' website satisfaction (i.e. satisfaction with the attractiveness, comprehensibility and emotional support from the website) and recall of information. In an online experiment, 174 younger (<65 years) and older (≥65 years) colorectal cancer patients were randomly exposed to a webpage about transanal endoscopic microsurgery consisting of either text-only information, text with two cognitive illustrations or text with two affective illustrations. In general, adding cognitive illustrations compared with text-only information improved the satisfaction with the attractiveness of the website in both younger and older patients. For older patients in particular, cognitive illustrations facilitated recall of cancer information: whereas older patients recalled less information overall compared with younger patients (39% vs. 50%), no statistically significant differences in age on recall were observed when cognitive illustrations were added to text. Furthermore, older patients were more satisfied with the emotional support from the website than younger patients, especially when affective illustrations were present. Our results suggest that effective online cancer communication for ageing populations involves considering both cognitive and affective illustrations to enhance website satisfaction and recall of cancer information.

The effectiveness of health animations in audiences with different health literacy levels: an experimental study

BACKGROUND

Processing Web-based health information can be difficult, especially for people with low health literacy. Presenting health information in an audiovisual format, such as animation, is expected to improve understanding among low health literate audiences.

OBJECTIVE

The aim of this paper is to investigate what features of spoken health animations improve information recall and attitudes and whether there are differences between health literacy groups.

METHODS

We conducted an online experiment among 231 participants aged 55 years or older with either low or high health literacy. A 2 (spoken vs written text) x 2 (illustration vs animation) design was used. Participants were randomly exposed to one of the four experimental messages, all providing the same information on colorectal cancer screening.

RESULTS

The results showed that, among people with low health literacy, spoken messages about colorectal cancer screening improved recall (P=.03) and attitudes (P=.02) compared to written messages. Animations alone did not improve recall, but when combined with spoken text, they significantly improved recall in this group (P=.02). When exposed to spoken animations, people with low health literacy recalled the same amount of information as their high health literate counterparts (P=.12), whereas in all other conditions people with high health literacy recalled more information compared to low health literate individuals. For people with low health literacy, positive attitudes mediated the relationship between spoken text and the intention to have a colorectal cancer screening (b=.12; 95% CI 0.02-0.25).

CONCLUSIONS

We conclude that spoken animation is the best way to communicate complex health information to people with low health literacy. This format can even bridge the information processing gap between audiences with low and high health literacy as the recall differences between the two groups are eliminated. As animations do not negatively influence high health literate audiences, it is concluded that information adapted to audiences with low health literacy suits people with high health literacy as well.

A content analysis of visual cancer information: prevalence and use of photographs and illustrations in printed health materials

Researchers and practitioners have an increasing interest in visual components of health information and health communication messages. This study contributes to this evolving body of research by providing an account of the visual images and information featured in printed cancer communication materials. Using content analysis, 147 pamphlets and 858 images were examined to determine how frequently images are used in printed materials, what types of images are used, what information is conveyed visually, and whether or not current recommendations for the inclusion of visual content were being followed. Although visual messages were found to be common in printed health materials, existing recommendations about the inclusion of visual content were only partially followed. Results are discussed in terms of how relevant theoretical frameworks in the areas of behavior change and visual persuasion seem to be used in these materials, as well as how more theory-oriented research is necessary in visual messaging efforts.
