Are psychophysiological arousal and self-reported emotional stress during an oncological consultation related to memory of medical information? An experimental study

Effects of Prognostic Communication Strategies on Prognostic Perceptions, Treatment Decisions and End-Of-Life Anticipation in Advanced Cancer: An Experimental Study among Analogue Patients

CONTEXT

Evidence-based guidance for oncologists on how to communicate prognosis is scarce.

OBJECTIVES

To investigate the effects of prognostic communication strategies (prognostic disclosure vs. communication of unpredictability vs. non-disclosure; standard vs. standard and best-case vs. standard, best- and worst-case survival scenarios; numerical vs. word-based estimates) on prognostic perceptions, treatment decision-making and end-of-life anticipation in advanced cancer.

METHODS

This experimental study used eight videos of a scripted oncological consultation, varying only in prognostic communication strategies. Cancer-naive individuals, who imagined being the depicted patient, completed surveys before and after watching one video (n = 1036).

RESULTS

Individuals generally perceived dying within 1 year as more likely after prognostic disclosure, compared to communication of unpredictability or non-disclosure (P < 0.001), and after numerical versus word-based estimates (P < 0.001). Individuals felt better informed about prognosis to decide about treatment after prognostic disclosure, compared to communication of unpredictability or non-disclosure (P < 0.001); after communication of unpredictability versus non-disclosure (P < 0.001); and after numerical versus word-based estimates (P = 0.017). Chemotherapy was more often favored after prognostic disclosure versus non-disclosure (P = 0.010), but less often after numerical versus word-based estimates (P < 0.001). Individuals felt more certain about the treatment decision after prognostic disclosure, compared to communication of unpredictability or non-disclosure (P < 0.001). Effects of different survival scenarios were absent. No effects on end-of-life anticipation were observed. Evidence for moderating individual characteristics was limited.

CONCLUSION

If and how oncologists discuss prognosis can influence how individuals perceive prognosis, which treatment they prefer, and how they feel about treatment decisions. Communicating numerical estimates may stimulate prognostic understanding and informed treatment decision-making.

Effects of prognostic communication strategies on emotions, coping, and appreciation of consultations: An experimental study in advanced cancer

OBJECTIVES

We aimed to investigate effects of prognostic communication strategies on emotions, coping, and appreciation of consultations in advanced cancer.

METHODS

For this experimental study, we created 8 videos of a scripted oncological consultation, only varying in prognostic communication strategies. Disease-naive individuals (n = 1036) completed surveys before and after watching 1 video, while imagining being the depicted cancer patient. We investigated effects of the type of disclosure (prognostic disclosure vs. communication of unpredictability vs. non-disclosure) and content of disclosure (standard vs. standard and best-case vs. standard, best- and worst-case survival scenarios; numerical vs. word-based estimates) on emotions, coping, and appreciation of consultations. Moderating effects of individual characteristics were tested.

RESULTS

Participants generally reported more satisfaction (p < .001) after prognostic disclosure versus communication of unpredictability and less uncertainty (p = .042), more satisfaction (p = .005), and more desirability (p = .016) regarding prognostic information after numerical versus word-based estimates. Effects of different survival scenarios were absent. Prognostic communication strategies lacked effects on emotions and coping. Significant moderators included prognostic information preference and uncertainty tolerance.

SIGNIFICANCE OF RESULTS

In an experimental setting, prognostic disclosure does not cause more negative emotions than non-disclosure and numerical estimates are more strongly appreciated than words. Oncologists' worries about harming patients should not preclude disclosing (precise) prognostic information, yet sensitivity to individual preferences and characteristics remains pivotal.

Using expert opinion rounds to develop valid and realistic manipulations for experimental video-vignette research: Results from a study on clinicians' (un)reasonable argumentative support for treatment decisions in neonatal care

OBJECTIVE

To develop valid and realistic manipulations for video-vignette research using expert opinion rounds, in preparation of an experimental study on clinicians' (un)reasonable argumentative support for treatment decisions in neonatal care.

METHODS

In three rounds, N = 37 participants (parents/clinicians/researchers) provided feedback on four video-vignette scripts and completed listing, ranking, and rating exercises to determine which (un)reasonable arguments clinicians may provide to support treatment decisions.

RESULTS

Round 1: participants deemed the scripts realistic. They judged that, on average, clinicians should provide two arguments for a treatment decision. They listed 13-20 reasonable arguments, depending on the script. Round 2: participants ranked the two most salient, reasonable arguments per script. Round 3: participants rated the most plausible, unreasonable arguments from a predefined list. These results guided the design of 12 experimental conditions.

CONCLUSION

Expert opinion rounds are an effective method to develop video-vignettes that are theoretically sound and ecologically realistic and offer a powerful means to include stakeholders in experimental research design. Our study yielded some preliminary insights into what are considered prevalent (un)reasonable arguments for clinicians' treatment plans.

PRACTICE IMPLICATIONS

We provide hands-on guidelines on involving stakeholders in the design of video-vignette experiments and the development of video-based health communication interventions - both for research and practice.

Negative language use of the physiotherapist in low back pain education impacts anxiety and illness beliefs: A randomised controlled trial in healthy respondents

OBJECTIVE

This study aimed to determine the effect of physiotherapists' negative language use on nocebo effects of state anxiety and illness beliefs.

METHODS

A web-based randomised controlled trial included adults without recent musculoskeletal pain. The intervention was a short educational video about low back pain using negative language (nocebo condition: n = 87) versus a video using neutral or positive language (control condition: n = 82). State anxiety was assessed using the State-Trait Anxiety Inventory. Illness beliefs were assessed using the Illness Perception Questionnaire.

RESULTS

Nocebo and control groups differed in outcome measures (MANOVA Pillai's trace = 0.22, F = 4.98; df = (9,159), p < 0.001). Post-hoc analyses showed a medium to large effect for the nocebo condition on anxiety (d = 0.71, 95% CI 0.4 -1.0). The nocebo group also had higher scores in three illness beliefs: beliefs on timeline (d = 0.45, 95% CI 0.14 - 0.75), treatment control (d = 0.43, 95% CI 0.12 - 0.74) and concern (d = 0.47, 95% CI 0.16 - 0.78).

CONCLUSION

Physiotherapists' use of negative language contributes directly to a higher state anxiety and illness beliefs that can trigger the nocebo effects in the recipient PRACTICE IMPLICATIONS: Negative language use should be avoided.

Methodological choices in experimental research on medical communication using vignettes: The impact of gender congruence and vignette modality

OBJECTIVE

Experimental vignette designs are used to systematically test the effects of medical communication. We tested the impact of two methodological choices -gender congruence and vignette modality- on analogue patient reported outcomes.

METHODS

In an online experiment using a vignette portraying an oncological bad news consultation, we manipulated (1) gender congruence between the analogue and the vignette patient, and (2) vignette modality, i.e., text, audio, or video. Cancer-naïve students acting as analogue patients (N = 209, 22 ± 3 years old, 75% F) were assigned one randomly-selected vignette variant and completed questionnaires. Using 3 × 2 (repeated-measures) ANOVAs, we tested main and interaction effects of gender congruence and modality on self-reported engagement, recall, trust, satisfaction and anxiety.

RESULTS

We found no main effects of gender congruence or modality on any of the outcomes, nor any interaction effects between modality and congruence.

CONCLUSION

Our results indicate that researchers may needlessly create gender-congruent vignettes at considerable cost and effort. Also, the currently assumed superiority of videos over other modalities for experimental vignette-based research may be inaccurate.

PRACTICE IMPLICATIONS

Although further testing in an offline format and among different populations is warranted, decisions regarding gender congruence and modality for future vignette-based studies should be based primarily on their specific aims.

Communicating the diagnosis of cancer or depression: Results of a randomized controlled online study using video vignettes

Background

Communicating a diagnosis is highly important, yet complex, especially in the context of cancer and mental disorders. The aim was to explore the communication style of an oncologist vs. psychotherapist in an online study.

Methods

Patients (N = 136: 65 cancer, 71 depression) were randomly assigned to watch a standardized video vignette with one of two communication styles (empathic vs. unempathic). Outcome measures of affectivity, information recall, communication skills, empathy and trust were applied.

Results

Regardless of diagnosis, empathic communication was associated with the perception of a significantly more empathic (p < 0.001, ηpartial2 = 0.08) and trustworthy practitioner (p = 0.014, ηpartial2 = 0.04) with better communication skills (p = 0.013, ηpartial2 = 0.05). Cancer patients reported a larger decrease in positive affect (p < 0.001, ηpartial2 = 0.15) and a larger increase in negative affect (p < 0.001, ηpartial2 = 0.14) from pre‐ to post‐video than depressive patients. Highly relevant information was recalled better in both groups (p < 0.001, d = 0.61–1.06).

Conclusions

The results highlight the importance of empathy while communicating both a diagnosis of cancer and a mental disorder. Further research should focus on the communication of a mental disorder in association with cancer.

Fostering Patient Choice Awareness and Presenting Treatment Options Neutrally: A Randomized Trial to Assess the Effect on Perceived Room for Involvement in Decision Making

Purpose

Shared decision making calls for clinician communication strategies that aim to foster choice awareness and to present treatment options neutrally, such as by not showing a preference. Evidence for the effectiveness of these communication strategies to enhance patient involvement in treatment decision making is lacking. We tested the effects of 2 strategies in an online randomized video-vignettes experiment.

Methods

We developed disease-specific video vignettes for rheumatic disease, cancer, and kidney disease showcasing a physician presenting 2 treatment options. We tested the strategies in a 2 (choice awareness communication present/absent) by 2 (physician preference communication present/absent) randomized between-subjects design. We asked patients and disease-naïve participants to view 1 video vignette while imagining being the patient and to report perceived room for involvement (primary outcome), understanding of treatment information, treatment preference, satisfaction with the consultation, and trust in the physician (secondary outcomes). Differences across experimental conditions were assessed using 2-way analyses of variance.

Results

A total of 324 patients and 360 disease-naïve respondents participated (mean age, 52 ± 14.7 y, 54% female, 56% lower educated, mean health literacy, 12 ± 2.1 on a 3–15 scale). The results showed that choice awareness communication had a positive (M_present = 5.2 v. M_absent = 5.0, P = 0.042, η²_partial = 0.006) and physician preference communication had no (M_present = 5.0 v. M_absent = 5.1, P = 0.144, η²_partial = 0.003) significant effect on perceived room for involvement in decision making. Physician preference communication steered patients toward preferring that treatment option (M_present = 4.7 v. M_absent = 5.3, P = 0.006, η²_partial = 0.011). The strategies had no significant effect on understanding, satisfaction, or trust.

Conclusions

This is the first experimental evidence for a small effect of fostering choice awareness and no effect of physician preference on perceived room to participate in decision making. Physician preference steered patients toward preferring that option.

A randomized experimental study to test the effects of discussing uncertainty during cancer genetic counseling: different strategies, different outcomes?

Uncertainty is increasingly discussed during genetic counseling due to innovative techniques, e.g., multigene panel testing. Discussions about uncertainty may impact counselees variably, depending on counselors' communication styles. Ideally, the discussion of uncertainty enables counselees to cope with uncertainty and make well-informed decisions about testing. We examined the impact of how counselors convey uncertainty and address counselees' uncertainty, and explored the role of individual characteristics. Therefore, a randomized controlled experiment using videos was conducted. Former counselees (N = 224) viewed one video depicting a genetic consultation about multigene panel testing. The extent of counselors' communication of uncertainty (comprehensive vs. the essence) and their response to counselees' uncertainty expressions (providing information vs. providing space for emotions vs. normalizing and counterbalancing uncertainty) were systematically manipulated. Individual characteristics, e.g., uncertainty tolerance, were assessed, as well as outcome variables (primary outcomes: feelings of uncertainty and information recall). No effects were found on primary outcomes. Participants were most satisfied when the essence was communicated, combined with providing information or providing space responses (p = 0.002). Comprehensive information resulted in less perceived steering toward testing (p = 0.005). Participants with lower uncertainty tolerance or higher trait anxiety were less confident about their understanding when receiving comprehensive information (p = 0.025). Participants seeking information experienced less uncertainty (p = 0.003), and trusted their counselor more (p = 0.028), when the counselor used information providing responses. In sum, the impact of discussing uncertainty primarily depends on individual characteristics. Practical guidelines should address how to tailor the discussion of uncertainty.

Physiological Correlates of Processing Health-Related Information: An Idea for the Adoption of a Foreign Field

Measuring health may refer to the measurement of general health status through measures of physical function, pain, social health, psychological aspects, and specific disease. Almost no evidence is available on the possible interaction of physiological measures and correlating emotional–affective states that are triggered by dealing with individual health-relevant issues and their specific processing modes. Public health research has long been concerned with the processing of health-related information. However, it is not yet clear which factors influence access and the handling of health-related information in detail. One way to close this research gap could be adopting methods from neurocognitive experiments to add psychophysiological data to existing approaches in health-related research. In this article, we present some of these methods and give a narrative overview and description of their usefulness for enlarged research in public health.

Any progress in informed consenting for cancer treatment? Results from a cross sectional analysis at a comprehensive cancer center

Purpose

Informed consent is required prior to any medical procedure. In the context of cancer treatment, special efforts are needed to inform cancer patients properly about treatment, potential sequelae and alternative therapies. Little is known about the effectiveness of current informed consent strategies and patients’ individual satisfaction. Given the heterogeneity in terms of age, education, sex and other factors, detailed understanding of patients’ comprehension and perception is the basis for further optimization of the informed consent process, which was the aim of the current investigation.

Methods

Patients with a new cancer diagnosis and recent informed consent were asked to complete a questionnaire about satisfaction, comprehension, time management, physician–patient relationship and other items of the informed consent process. Patients were followed for 6 months and invited to complete a follow-up questionnaire.

Results

In total, 89 patients completed the first questionnaire and 52 the follow-up questionnaire. Subjective understanding was assumed high, however, this did not correlate with objective understanding. Age and education were identified as influencing factors for comprehension. 85% of the patients were satisfied with the information provided. A major gap was the information on alternative therapies. Moreover, not all patients perceived the consent dialog as such, and particularly the individual treatment intention partially remained unclear for some patients.

Conclusions

To ensure that informed consent is based on solid understanding, informed consenting must be patient-centered and consider the individual expectations, needs and abilities of cancer patients. Further studies are required to develop tailored informed consent strategies.

Communicating treatment risks and benefits to cancer patients: a systematic review of communication methods

PURPOSE

Cancer patients are increasingly involved in decision-making processes. Hence, clinicians need to inform patients about the risks and benefits of different treatment options in order for patients to make well informed decisions. The aim of this review is to determine the effects of methods of communicating prognostic information about (1) disease progression (survival, progression, recurrence and remission), (2) side effects and complications and (3) health-related quality of life (HRQL) on cognitive, affective and behavioral outcomes in cancer patients.

METHODS

A literature search was performed to select articles that were published up to  November 2019 and that examined verbal and/or visual risk communication interventions in an oncological clinical setting.

RESULTS

The search yielded 14,875 studies; 28 studies were ultimately included. For disease progression information, we found that framing affects treatment choice. Furthermore, limiting the amount of progression information in a graphical display could benefit patients' understanding of risks and benefits. For prognostic information about side effects and complications, precise and defined risk information was better understood than information presented in words. When displaying HRQL data, no consensus was found on which graph type to use.

CONCLUSION

Great heterogeneity in the results and methodology and in the compared communication formats precluded us from drawing any further conclusions. Practical implications for clinicians are to consider the effects that different types of framing might have on the patient and to not rely exclusively on words to describe risks, but rather include at least some form of numbers or visualization.

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).

Fear and forget: how anxiety impacts information recall in newly diagnosed cancer patients visiting a fast-track clinic

INTRODUCTION

One-day fast track programs for cancer diagnostics and treatment planning are increasingly being implemented in health care. Fast-track programs are highly effective at reducing waiting times, and thus well received by patients and healthcare providers. However, these programs may also burden patients, as patients generally receive a lot of information from multiple healthcare providers within a short time span. This might increase anxiety and negatively impact recall of medical information in newly diagnosed patients. This study examines whether anxiety influences information recall at the moment of diagnosis, and whether this relation differs for younger and older patients.

METHODS

Data were collected from 78 colorectal cancer patients visiting a one-day fast-track multidisciplinary outpatient clinic. All consultations that took place were recorded on a video. Anxiety was measured at baseline (T1) and immediately after consultations (T2) with the STAI-6. Information recall was assessed by telephone within 36-48 hours after patients' visit (T3) using open questions.

RESULTS

After consultations (T2), 32% of patients experienced clinical anxiety levels. Patients recalled ∼60% of medical information (T3). Information recall was negatively impacted by anxiety (β = -.28, p = .011), and negatively related to higher age (β = -.23, p = .031), and lower education level (β = .27, p = .013). Although older patients (M = 53.99) recalled 11% less information than younger patients (M = 64.84), age was not related to anxiety and did not moderate the anxiety-recall relationship.

CONCLUSION

High levels of anxiety after receiving a cancer diagnosis negatively influence how much information patients remember after visiting a one-day fast-track clinic. This calls for interventions that may reduce patients' anxiety as much as reasonably possible and support patients' information recall. Researchers, practitioners, and hospitals are encouraged to continue exploring ways to optimize information provision to cancer patients in current modern healthcare.

Does silence speak louder than words? The impact of oncologists' emotion-oriented communication on analogue patients' information recall and emotional stress

OBJECTIVE

The impact of two types of oncologists' emotion-oriented communication on participants' recall of medical information was investigated, and the potential mediation by a reduction in emotional stress. Additionally, moderation effects by personal characteristics were explored.

METHODS

An oncologist's communication in response to a patient's emotional expressions was manipulated during a videotaped, scripted bad-news consultation. Three conditions were created: 1) standard communication, 2) emotion-oriented silence, and 3) emotion-oriented speech. Participants (N = 217) were randomly allocated to one of the three conditions. Measurements included information recall (free recall and recognition), emotional stress (self-reported and physiological), and personal characteristics.

RESULTS

Emotion-oriented silence (p = .002) and speech (p = .019) enhanced information recognition compared to standard communication. No differences in free recall were found. Emotional stress did not mediate these relations. Poorer functional health literacy predicted poorer recognition, but this was counteracted by emotion-oriented communication.

CONCLUSIONS

By means of acknowledging, exploring, empathic and supportive statements, and attentive silence, the oncologist's communication resulted in better information recognition. How oncologists' communication impacts patients' information recall warrants further investigation, as this could not be explained by reducing emotional stress.

PRACTICE IMPLICATIONS

These insights will help educators to validate the relevance of emotion-oriented strategies, and encourage oncologists to adopt them.

Affective communication during bad news consultation. Effect on analogue patients' heart rate variability and recall

OBJECTIVE

The aim of the study was to investigate the effect of physicians' supportive communication on analogue patients' (APs) heart rate variability (HRV) and recall, while watching a video of palliative treatment being explained to a female patient.

METHODS

Sixty healthy women, acting as APs, were randomly assigned to watch one of two versions (standard vs. affective) of a scripted video-vignette of a bad news consultation to a female patient. The physician's communication differed only in the delivery of four supportive comments. Empathy, support and engagement perception were assessed by three questions. APs' HR was recorded during video-observation and recall was assessed immediately after. HRV was determined through measures defined in time and frequency domains.

RESULTS

Data of 54 APs (27 + 27) were included. The group with supportive communication perceived the physician as more empathic and supportive. Intra- and Inter-group comparisons suggested a greater sense of stress in the standard communication group. Recall did not differ in the two groups.

CONCLUSION AND PRACTICE IMPLICATIONS

Findings show that the use of supportive expressions contribute to the perception of the physician as more empathic, potentially buffer patients' arousal after a bad news announcement, but does not confirm a positive impact on general recall.

Patients' autonomic activation during clinical interaction: A review of empirical studies

OBJECTIVE

To investigate how patients' autonomic responses are related to verbal or non-verbal communication during clinical encounters.

METHODS

The SCOPUS database was searched to identify papers. Studies were included if measures of autonomic arousal were related to patients' emotions or patient-clinician interaction during clinical consultations such as psychotherapy, counseling or medical interviews. The search was conducted according to PRISMA criteria. The included studies were assessed using the 16 item quality assessment tool QATSDD.

RESULTS

A total of 24 publications were identified. The studies varied greatly in design and quality. However, a few trends could be observed across studies. Patients' expressions of emotions were associated with significant autonomic arousal. Clinician behavior affected arousal levels; and in a few studies, a patient centered way of presenting information was found to attenuate arousal level, interpreted as stress reduction. There was a general, but not consistent, trend in the reduction of arousal level over time within the consultation. Examples of individual differences in autonomic responses were found.

CONCLUSION AND PRACTICE IMPLICATIONS

Increased awareness of potential impact of clinician behavior on patient' arousal level may be helpful for clinicians, in particular how different communication styles may augment or attenuate arousal in response to stressors.

Studying medical communication with video vignettes: a randomized study on how variations in video-vignette introduction format and camera focus influence analogue patients' engagement

BACKGROUND

Video vignettes are used to test the effects of physicians' communication on patient outcomes. Methodological choices in video-vignette development may have far-stretching consequences for participants' engagement with the video, and thus the ecological validity of this design. To supplement the scant evidence in this field, this study tested how variations in video-vignette introduction format and camera focus influence participants' engagement with a video vignette showing a bad news consultation.

METHODS

Introduction format (A = audiovisual vs. B = written) and camera focus (1 = the physician only, 2 = the physician and the patient at neutral moments alternately, 3 = the physician and the patient at emotional moments alternately) were varied in a randomized 2 × 3 between-subjects design. One hundred eighty-one students were randomly assigned to watch one of the six resulting video-vignette conditions as so-called analogue patients, i.e., they were instructed to imagine themselves being in the video patient's situation. Four dimensions of self-reported engagement were assessed retrospectively. Emotional engagement was additionally measured by recording participants' electrodermal and cardiovascular activity continuously while watching. Analyses of variance were used to test the effects of introduction format, camera focus and their interaction.

RESULTS

The audiovisual introduction induced a stronger blood pressure response during watching the introduction (p = 0.048, [Formula: see text]= 0.05) and the consultation part of the vignette (p = 0.051, [Formula: see text]= 0.05), when compared to the written introduction. With respect to camera focus, results revealed that the variant focusing on the patient at emotional moments evoked a higher level of electrodermal activity (p = 0.003, [Formula: see text]= 0.06), when compared to the other two variants. Furthermore, an interaction effect was shown on self-reported emotional engagement (p = 0.045, [Formula: see text]= 0.04): the physician-only variant resulted in lower emotional engagement if the vignette was preceded by the audiovisual introduction. No effects were shown on the other dimensions of self-reported engagement.

CONCLUSIONS

Our findings imply that using an audiovisual introduction combined with alternating camera focus depicting patient's emotions results in the highest levels of emotional engagement in analogue patients. This evidence can inform methodological decisions during the development of video vignettes, and thereby enhance the ecological validity of future video-vignettes studies.

How oncologists' communication improves (analogue) patients' recall of information. A randomized video-vignettes study

OBJECTIVE

Cancer patients need information provision to cope with their disease. However, only 20-60% of information provided during consultations is remembered. This study aimed to investigate whether oncologists' use of trust-conveying communication, characterized by communicating competence, honesty and caring, enhances patients' memory. Moreover, we aimed to investigate if this hypothetical relationship is mediated by a reduction in psychophysiological arousal during the consultation.

METHODS

An experimental design was used, allowing for conclusion about causality. Two versions of a scripted video-taped consultation were used in which the oncologist adopted either a standard or a trust-conveying communication style. 97 cancer-naive individuals acted as analogue patients and were randomly assigned to watch one of the consultations.

RESULTS

Free recall, assessed 24-28h after viewing, was higher (p=0.039) in the trust-conveying condition (65.3% versus 59.5%). Recognition did not differ (p=0.502). Psychophysiological assessment during watching showed a smaller heart rate response in the trust-conveying condition (p=0.037). No mediation effect nor an effect on electrodermal activity was found.

CONCLUSION

These results suggest that oncologists' use of trust-conveying communication could increase patients' free recall of information and diminish their cardiovascular response.

PRACTICE IMPLICATIONS

The underlying mechanisms by which oncologists' communication influences information recall warrants further investigation.
