Future-oriented Emotions and Decisions to Receive Genomic Testing Results Among U.S. Adults of African Ancestry.

BACKGROUND: Future-oriented emotions are associated with consequential health decision-making, including genomic testing decisions. However, little is known about the relative role of various future-oriented emotions in such decisions. Moreover, most research on predictors of decision making regarding genomic testing is conducted with white participants. PURPOSE: This study examined the role of future-oriented emotions in decisions to receive genomic testing results in U.S. individuals of African descent. METHODS: We analyzed cross-sectional survey data from a genomic sequencing cohort (N = 408). All participants identified as African, African-American, or Afro-Caribbean (Mage = 56.3, 74.7% female). Participants completed measures assessing anticipatory affect (worry about genetic testing results), anticipated distress (feeling devastated if genetic testing showed an increased risk for fatal disease), and anticipated regret (regretting a decision not to learn results). Outcomes were intentions for learning actionable, nonactionable, and carrier results. RESULTS: Anticipated regret was robustly positively associated with intentions to receive actionable (b = 0.28, p < .001), nonactionable (b = 0.39, p < .001), and carrier (b = 0.30, p < .001) results. Anticipated distress was negatively associated with intentions to receive nonactionable results only (b = -0.16, p < .01). Anticipatory negative affect (worry) was not associated with intentions. At higher levels of anticipated regret, anticipated distress was less strongly associated with intentions to receive nonactionable results (b = 0.14, p = .02). CONCLUSIONS: Our results highlight the role of future-oriented emotions in genomic testing among participants who are typically underrepresented in genomic testing studies and behavioral medicine broadly. Future work should examine whether interventions targeting future-oriented emotions such as anticipated regret may have clinically meaningful effects in genetic counseling in similar cohorts.

Future-oriented emotions (emotions directed toward a future outcome, such as worrying about a future outcome, or expecting to feel distress or regret if a particular outcome occurs) are important predictors of health decisions, including decisions to seek and receive genomic testing results. Understanding how such factors relate to decisions to receive genetic testing results is particularly important in medically-underserved groups such as individuals of African ancestry, who are underrepresented in genomics and behavioral science research. We analyzed survey responses from a genomic sequencing cohort where all 408 participants identified as African, African-American, or Afro-Caribbean, and were asked about their level of worry, anticipated distress, and anticipated regret about results, plus their interest in receiving three types of genomic testing results from the study. We found that participants who expected that they would regret their decision to not learn the results had stronger intentions to receive all three types of results; those who expected to feel distressed by a genetic testing result that showed an increased risk for a fatal disease were less interested in nonactionable genetic testing results specifically. Our results highlight the differing roles of specific types of future-oriented emotions in genomic testing decisions, among participants who are typically underrepresented in this type of research.

Perceptions and tolerance of uncertainty: relationship to trust in COVID-19 health information and vaccine hesitancy.

The COVID-19 crisis has exposed the public to considerable scientific uncertainty, which may promote vaccine hesitancy among individuals with lower tolerance of uncertainty. In a national sample of US adults in May-June 2020, we examined how both perceptions of uncertainty about COVID-19 and trait-level differences in tolerance of uncertainty arising from various sources (risk, ambiguity, and complexity) are related to vaccine hesitancy-related outcomes, including trust in COVID-19 information, COVID-19 vaccine intentions, and beliefs that COVID-19 vaccines should undergo a longer testing period before being released to the public. Overall, perceptions of COVID-19 uncertainty were not associated with trust in information, vaccine intentions, or beliefs about vaccine testing. However, higher tolerance of risk was associated with lower intentions to get vaccinated, and lower tolerance of ambiguity was associated with lower intentions to get vaccinated and preferring a longer period of vaccine testing. Critically, perceptions of COVID-19 uncertainty and trait-level tolerance for uncertainty also interacted as predicted, such that greater perceived COVID-19 uncertainty was more negatively associated with trust in COVID-19 information among individuals with lower tolerance for risk and ambiguity. Thus, although perceptions of uncertainty regarding COVID-19 may not reduce trust and vaccine hesitancy for all individuals, trait-level tolerance of uncertainty arising from various sources may have both direct and moderating effects on these outcomes. These findings can inform public health communication or other interventions to increase COVID-19 vaccination uptake.

Increasing Receptivity to COVID-19 Public Health Messages with Self-Affirmation and Self vs. Other Framing.

There remains an urgent need for effective communication about the importance of widespread adherence to behavioral recommendations to control the COVID-19 pandemic that will also reduce resistance to such guidance. We examined two strategies for COVID-19 communication- (1) self-affirmation (reflecting on a personal value in order to boost self-integrity and reduce defensiveness to potentially threatening information); and (2) manipulating self/other message framing - and moderation of these strategies by COVID-19 risk. 600 participants (Mage = 32.55, 51% female) were recruited for an online study and, after assessment of risk factors for severe COVID-19 infection, were exposed to the experimental manipulations. Three classes of defensive responses were considered as outcomes of interest: reactance, attitudinal responses, and behavioral responses. We found that participants derogated the self-focused message more than the other-focused message. Further, other-focused messaging and/or self-affirmation were more likely to elicit positive responses among individuals at higher risk for COVID-19 complications. Our findings suggest having individuals affirm values prior to viewing COVID-19 messages, and framing messages in terms of the importance of protecting others, may be beneficial strategies for encouraging responsiveness - particularly if the targets of such messages are at risk of COVID-19 complications themselves.

The role of future-oriented affect in engagement with genomic testing results.

Future-oriented emotions such as anticipatory affect (i.e., current affect experienced regarding a potential future outcome) and anticipated affect (i.e., expectations about potential future affect), are uniquely associated with health decision-making (e.g., electing to receive results of genomic testing). This study investigated the degree to which negative anticipated and anticipatory emotions predict health decision making over time, and whether such emotions predict social, emotional, and behavioral responses to anticipated information (e.g., genomic testing results). 461 participants (M age = 63.9, SD = 5.61, 46% female) in a genomic sequencing cohort who elected to receive genomic sequencing (carrier) results were included in the current study. Anticipated and anticipatory affect about sequencing results were assessed at baseline. Psychological and behavioral responses to sequencing results, including participants' reported anxiety, decisional conflict, and distress about sequencing results, whether they shared results with family members, and their intentions to continue learning results in the future, were collected immediately, one month, and/or six months after receiving results. More negative anticipated and anticipatory affect at baseline was significantly and independently associated with lower intentions to continue learning results in the future, as well as higher levels of anxiety and uncertainty at multiple time points after receiving results. Anticipated negative affect was also associated with greater decisional conflict, and anticipatory negative affect was also associated with greater distress after receiving results. Future-oriented emotions may play an important role in decisions that unfold over time, with implications for genomic testing, behavioral medicine, and health decision-making broadly.

Women's exercise identity increases after a 16-week exercise RCT and is linked to behavior maintenance at follow-up.

BACKGROUND: Regular exercise is critical for disease prevention, but adherence to public health guidelines is poor. Exercise identity is purported to be associated with exercise behavior maintenance, but the extant literature is largely cross-sectional and of low/modest quality. PURPOSE: To examine change in exercise identity after completion of a supervised exercise intervention, as well as associations between change in exercise identity and exercise maintenance at 6-months follow-up. METHODS: N = 276 insufficiently physically active women were randomized to a 16-week, supervised exercise training intervention with 4 conditions fully crossed on intensity (vigorous/moderate) and duration (long/short). Exercise identity was measured pre- and post-intervention and assessments of exercise motivation and behavior frequency were collected at 6-months post-intervention follow-up. RESULTS: On average, participants experienced a statistically significant change in exercise identity over the course of the intervention, t(128) = 7.94, p < .001, but identity change scores did not differ across training conditions, p = .91. Identity change was significantly positively related to changes in other theory-informed, motivation-based determinants of exercise, and predicted an additional 16.17 minutes of exercise per week, on average, at follow-up, b = 16.76, t(103) = 2.30, p = .023. CONCLUSIONS: Participants experienced increased self-identification with exercise after 16-weeks of training, but training volume did not influence the amount of identity change. As expected, greater change in exercise identity was associated with higher levels of exercise behavior at 6-months post-intervention follow-up (ClinicalTrials.gov number NCT02032628).

Mindfulness Versus Distraction to Improve Affective Response and Promote Cardiovascular Exercise Behavior.

BACKGROUND: Variation in affective response to exercise partially explains high levels of inactivity. Examining ways to improve affective responses to physical activity is, therefore, an important direction for research aiming to promote exercise behavior. PURPOSE: This study compares three strategies: mindfulness, distraction, and an associative focus comparison group as potential strategies to improve affective response to exercise and promote exercise behavior. METHODS: Seventy-eight insufficiently active individuals (M age 26.82, 74% female) were randomly assigned to one of the following three conditions: (a) mindfulness, (b) distraction, or (c) associative attentional focus. The study was divided into two phases, a laboratory session in which participants learned their assigned strategy and completed a 30 min supervised exercise bout and an at-home intervention in which participants used their assigned strategy while exercising on their own for 2 weeks and filled out daily surveys. RESULTS: Seventy-five participants completed the study. The central hypotheses were partially supported. Participants in the mindfulness and distraction conditions maintained more positive affective response to exercise over time compared to participants in the associative focus condition, whose affect became less positive over time (p = .04). Participants in the distraction condition experienced lower perceived exertion during exercise (p = .01). There were no condition differences in self-reported minutes exercised during follow-up, but participants in the mindfulness condition reported exercising for more days during the follow-up compared to the associative focus condition (p = .01). CONCLUSIONS: These findings suggest individuals wishing to increase their cardiovascular exercise could engage in mindfulness or distraction in order to make exercise feel less difficult and/or more affectively pleasant.

Feel good now or regret it later? The respective roles of affective attitudes and anticipated affective reactions for explaining health-promoting and health risk behavioral intentions.

Evidence supporting the incorporation of affective constructs, such as affective attitudes and anticipated regret, into theoretical models of health behavior has been mounting in recent years; however, the role of positive anticipated affective reactions (e.g., pride) has been largely unexplored. The purpose of the present investigation was to assess how affective attitudes and anticipated affective reactions (both pride and regret for performing a behavior or not) may provide distinct utility for understanding intentions to perform health-promoting and health risk behaviors over and above cognitive attitudes and other established theoretical constructs from the theory of planned behavior (TPB). Participants (N = 210) were recruited via Amazon's Mechanical Turk to complete a one-time online battery assessing TPB and affective constructs. Self-reported intentions served as the main outcome measure, and hierarchical linear modeling was used to examine the effects of TPB and affective constructs across behaviors. Controlling for TPB constructs, more positive affective attitudes and greater anticipated regret, but not anticipated pride, predicted intentions to engage in future health behaviors. Anticipated affective reactions contributed explanatory variance for intentions to perform health risk behaviors, but anticipated pride and regret were not associated with intentions to perform health risk behaviors. Contributions made via the inclusion of both positively and negatively valence anticipated affective reactions for both action and inaction (performing a behavior or not) across a range of health promoting and health risk behaviors are discussed, as well as implications for future intervention work.

Body mass index, diet, and exercise: testing possible linkages to breast cancer risk via DNA methylation.

PURPOSE: To examine DNA methylation as a mechanism linking diet, physical activity, weight status, and breast cancer risk. METHODS: Insufficiently active women of varying weight status, without a history of cancer, completed a maximal exercise test, clinical measurement of height and weight, and a dietary intake measure. They also provided blood samples, which were analyzed to ascertain average methylation of candidate genes related to breast cancer (BRCA1, RUNX3, GALNT9, and PAX6) and inflammation (TLR4 and TLR6). RESULTS: Elevated weight status (r = - .18, p < .05) and poorer aerobic fitness (r = .24, p < .01) were each associated with decreased methylation of inflammation genes. Methylation of inflammation genes statistically mediated the relationship between weight status and cancer gene methylation (standardized indirect effect = .12, p < .05) as well as between cardiorespiratory fitness and cancer gene methylation (standardized indirect effect = - .172, p < .01). However, recent dietary behavior was not associated with methylation of either inflammation or cancer genes. CONCLUSIONS: Both weight status and cardiovascular fitness are associated with methylation of genes associated with both inflammation and cancer. Methylation of inflammatory genes might serve as a mechanistic link between lifestyle factors and methylation changes in genes that increase risk for breast cancer.

Neural activation during delay discounting is associated with 6-month change in risky sexual behavior in adolescents.

Background: Identifying cognitive and neural mechanisms of decision making in adolescence can enhance understanding of, and interventions to reduce, risky health behaviors in adolescence. Delay discounting, or the propensity to discount the magnitude of temporally distal rewards, has been associated with diverse health risk behaviors, including risky sex. This cognitive process involves recruitment of reward and cognitive control brain regions, which develop on different trajectories in adolescence and are also implicated in real-world risky decision making. However, no extant research has examined how neural activation during delay discounting is associated with adolescents' risky sexual behavior. Purpose: To determine whether a relationship exists between adolescents' risky sexual behavior and neural activation during delay discounting. Methods: Adolescent participants completed a delay discounting paradigm during functional magnetic resonance imaging (fMRI) scanning, and they reported risky sexual behavior at baseline, 3-, 6-, 9-, and 12-month follow-up time points. Latent growth curve models were employed to determine relationships between brain activation during delay discounting and change in risky sexual behavior over time. Results: Greater activation in brain regions associated with reward and cognitive control (caudate, putamen, nucleus accumbens, anterior cingulate, insula, orbitofrontal cortex, inferior frontal gyrus, dorsolateral prefrontal cortex) during delay discounting was associated with lower mean levels of risky sexual behavior but greater growth over the period from baseline to 6 months. Conclusions: Neural activation during delay discounting is cross-sectionally and prospectively associated with risky sexual behavior in adolescence, highlighting a neural basis of risky decision-making as well as opportunities for early identification and intervention.

Risky Sex in High-Risk Adolescents: Associations with Alcohol Use, Marijuana Use, and Co-Occurring Use.

Risky sexual behavior and substance use appear to be interconnected behaviors among adolescents, but data are scarce regarding the extent to which sexual risk behavior is associated with high levels of marijuana and alcohol use, both separately and in combination. 301 adolescents were recruited from a short-term detention facility, and substance use and risky sexual behavior were assessed. We found that adolescents who frequently used marijuana, but not alcohol, reported significantly less risky sex as well as greater intentions to use condoms than either adolescents who frequently used alcohol, but not marijuana, or adolescents who frequently used both substances. Substance use status as a predictor of future risky sexual behavior followed a similar pattern. When designing interventions to reduce substance use in the context of risky sex, it might be especially effective to target efforts toward reducing harm associated with alcohol use, either alone or in combination with marijuana use.

Effects of Performance Versus Game-Based Mobile Applications on Response to Exercise.

BACKGROUND: Given the popularity of mobile applications (apps) designed to increase exercise participation, it is important to understand their effects on psychological predictors of exercise behavior. PURPOSE: This study tested a performance feedback-based app compared to a game-based app to examine their effects on aspects of immediate response to an exercise bout. METHODS: Twenty-eight participants completed a 30-min treadmill run while using one of two randomly assigned mobile running apps: Nike + Running, a performance-monitoring app which theoretically induces an associative, goal-driven state, or Zombies Run!, an app which turns the experience of running into a virtual reality game, theoretically inducing dissociation from primary exercise goals. RESULTS: The two conditions did not differ on primary motivational state outcomes; however, participants reported more associative attentional focus in the performance-monitoring app condition compared to more dissociative focus in the game-based app condition. CONCLUSIONS: Game-based and performance-tracking running apps may not have differential effects on goal motivation during exercise. However, game-based apps may help recreational exercisers dissociate from exercise more readily. Increasing the enjoyment of an exercise bout through the development of new and innovative mobile technologies is an important avenue for future research.

Developmental Cognitive Neuroscience of Adolescent Sexual Risk and Alcohol Use.

Human adolescents engage in very high rates of unprotected sex. This behavior has a high potential for unintended, serious, and sustained health consequences including HIV/AIDS. Despite these serious health consequences, we know little about the neural and cognitive factors that influence adolescents' decision-making around sex, and their potential overlap with behaviorally co-occurring risk behaviors, including alcohol use. Thus, in this review, we evaluate the developmental neuroscience of sexual risk and alcohol use for human adolescents with an eye to relevant prevention and intervention implications.

Advancing Health Disparities Science Through Social Epigenomics Research.

Importance: Although scientific and technological discoveries have improved the health of the US population overall, racial and ethnic minority (American Indian and Alaska Native, Asian, Black or African American, Hispanic or Latino, or Native Hawaiian and Pacific Islander persons) and socioeconomically disadvantaged populations continue to experience a disproportionate burden of disease and other adverse health conditions. To better understand and address the drivers of health disparities and inform the development of effective interventions, integrative mechanistic studies examining the dynamic interplay of multiple factors across the life course and even between generations are needed. The emerging field of social epigenomics, which seeks to link social stressors and protective factors to health status through the examination of epigenomic modifications of various biological pathways, is one promising area of research contributing to this need. Observations: This thematic issue of JAMA Network Open highlights new findings from the grantees of the National Institutes of Health (NIH) Social Epigenomics Program. These findings, taken together, examine the associations of a variety of social, behavioral, and structural factors throughout the life course with epigenomic and other biological changes among populations experiencing health disparities. The studies link early-life exposures, structural inequities, and behavioral factors and interventions to epigenetic changes, and in some studies, later health outcomes. While there is still more work to be done to fully characterize the mechanistic pathways linking social exposures to epigenetic changes and health outcomes, the body of work presented in this special issue represents solid progress toward this goal. Conclusions and Relevance: The studies highlighted in this special issue demonstrate important scientific progress in the complex integration of social determinants of health and health disparities with biological pathways and health outcomes to improve understanding of the mechanisms underlying health disparities among various underserved populations. Continued progress remains important in integrating different disciplines to transform the field of health disparities research.

Synergistic Opportunities for Affective Science and Behavior Change.

Behavior change can be challenging to facilitate and achieve. Behavior change frameworks largely focus on social cognitive determinants, omitting affective determinants or including them in a superficial way. However, evidence points to the role of affect in decision-making and behavior, particularly when the behavior at focus for change is affectively pleasant or when the behavior to be facilitated is affectively unpleasant. This paper identifies challenges and opportunities to further affective science by using behavior change as a context and, relatedly, to further the science of behavior change by leveraging theoretical and methodological innovations in affective science.

Understanding the Changing Landscape of Health Disparities in Chronic Liver Diseases and Liver Cancer.

Liver disease and liver cancer disparities in the U.S. are reflective of complex multiple determinants of health. This review describes the disproportionate burden of liver disease and liver cancer among racial, ethnic, sexual, and gender minority, rural, low socioeconomic status (SES) populations, and place-based contexts. The contributions of traditional and lifestyle-related risk factors (e.g., alcohol consumption, evitable toxin exposure, nutrition quality) and comorbid conditions (e.g., viral hepatitis, obesity, type II diabetes) to disparities is also explored. Biopsychosocial mechanisms defining the physiological consequences of inequities underlying these health disparities, including inflammation, allostatic load, genetics, epigenetics, and social epigenomics are described. Guided by the National Institute on Minority Health and Health Disparities (NIMHD) framework, integrative research of unexplored social and biological mechanisms of health disparities, appropriate methods and measures for early screening, diagnosis, assessment, and strategies for timely treatment and maintaining multidisciplinary care should be actively pursued. We review emerging research on adverse social determinants of liver health, such as structural racism, discrimination, stigma, SES, rising care-related costs, food insecurity, healthcare access, health literacy, and environmental exposures to pollutants. Limited research on protective factors of liver health is also described. Research from effective, multilevel, community-based interventions indicate a need for further intervention efforts that target both risk and protective factors to address health disparities. Policy-level impacts are also needed to reduce disparities. These insights are important, as the social contexts and inequities that influence determinants of liver disease/cancer have been worsened by the coronavirus disease-2019 pandemic and are forecasted to amplify disparities.

Affective Science Research: Perspectives and Priorities from the National Institutes of Health.

Affective science is a broad and burgeoning field, and the National Institutes of Health (NIH) support research on a similarly broad range of topics. Across NIH, funding is available for basic, translational, and intervention research, including research in non-human animals, healthy populations, and those with or at risk for disease. Multiple NIH Institutes and Centers have specific programs devoted to topics within the affective science umbrella. Here, we introduce the funding priorities of these six: the National Cancer Institute (NCI), National Center for Complementary and Integrative Health (NCCIH), National Institute of Mental Health (NIMH), National Institute on Aging (NIA), National Institute on Drug Abuse (NIDA), and National Institute on Minority Health and Health Disparities (NIMHD). We then discuss overlapping themes and offer a perspective on promising research directions.

Associations between absolute and relative electronic cigarette harm perceptions and information-seeking behaviours among US adult current, former and never smokers.

INTRODUCTION: Electronic cigarette (e-cigarette) harm perceptions and information seeking behaviours are both important antecedents of e-cigarette use, yet the relationship between them has been rarely studied. We assessed how absolute (e-cigarettes are harmful to my health) and relative harm perceptions (e-cigarettes are more/less harmful than cigarettes) were associated with specific e-cigarette information seeking behaviours in a sample of current, former and never cigarette smokers. METHODS: We used data from US adults in two cycles of the Health Information National Trends Survey (HINTS-FDA 2015, n = 3738; 2017, n = 1736). Analyses controlled for socio-demographics, ever e-cigarette use and survey cycle. Data were analysed between January and August 2020. RESULTS: Higher relative harm perceptions were associated with lower odds of having sought any information on e-cigarettes [adjusted odds ratio 0.61, 95% confidence interval (0.48, 0.84)] and on how to use e-cigarettes to quit smoking specifically [adjusted odds ratio 0.59, 95% confidence interval (0.38, 0.91)]. Smoking status did not moderate associations between absolute or relative harm perceptions and information seeking behaviours, nor was it associated with specific information seeking behaviours after adjusting for covariates. DISCUSSION AND CONCLUSIONS: The risks of e-cigarettes relative to combusted cigarettes (as opposed to the absolute risks of e-cigarettes) appear to be more important in individuals' information seeking behaviours about e-cigarettes. Public health messages could ensure that all individuals understand how one's health risk would change if they exclusively used e-cigarettes, switched to e-cigarettes completely or used both products.

Self-affirmation inductions to reduce defensive processing of threatening health risk information.

OBJECTIVE: Self-affirmation reduces defensiveness toward threatening health messages. In this study, we compared several possible self-affirmation inductions in order to identify the most effective strategy. DESIGN: Women at increased risk for breast cancer (i.e. who drink 7+ drinks per week) were recruited through Amazon Mechanical Turk (N = 1,056), randomly assigned to one of 11 self-affirmation conditions, and presented with an article about the link between alcohol intake and breast cancer risk. MAIN OUTCOME MEASURES: Participants answered questions that measured key indices of message acceptance (risk perception, message endorsement), future alcohol consumption intentions, and action plans to reduce alcohol intake. RESULTS: Participants who affirmed health vs. non-health values did not differ in behavioral intentions or action plans to reduce alcohol intake. General values vs. health essay affirmations led to higher odds of reporting some vs. no action plans to reduce alcohol consumption. Essay- vs. questionnaire-based inductions led to higher breast cancer worry and intentions to reduce alcohol consumption. CONCLUSION: Overall, self-affirmation inductions that include an explicit focus on values (general or health-related) and self-generation of affirming thoughts through essay writing, are most potent in changing behavioral intentions and action plans to change future health behavior.

Understanding responses to different types of conflicting information about cancer prevention.

BACKGROUND: Individuals are regularly exposed to conflicting information about health; however, understanding of how individuals respond to different types of conflicting information is limited. METHODS: In total, 1027 US adults were randomly assigned to 1 of 8 conflicting information messages about nutrition and cancer risk, depicting 1/4 conflicting information types (conflict in evidence - sources A and B agree the evidence is mixed; conflict between two expert sources - sources A and B present conflicting evidence about nutrition and cancer risk; conflict within the same expert source - source A changes its own recommendation about the evidence; no conflict control) crossed by 1/2 baseline recommendations with which new information conflicted (limit vs. do not limit red meat intake to reduce cancer risk). RESULTS: Compared to the control, each conflicting information type led to lower perceived scientific consensus about how much red meat one should eat (p < .001); conflict in evidence (p = .004) and between sources (p = .006) led to lower trust in scientists. Intentions to consume red meat more frequently were higher in the conflicting information conditions than control in the group initially told to "limit red meat" and lower in the "do not limit red meat" group (p = .022). Conflict within the same source led to higher perceived scientific consensus compared to conflict in evidence (p = .007) and between sources (p = .013); it also lowered intentions to consume red meat more frequently compared to conflict in evidence, but only in the "do not limit red meat" condition (p = .033). Conflict in evidence (p = .007) and within the same source (p = .013) increased cancer fatalism compared to conflict between sources. CONCLUSIONS: Conflict in scientific evidence and conflict arising from the same expert source (e.g., a changing public health guideline) may have pernicious effects. Future efforts could investigate how best to publicly communicate these instances of scientific conflict to minimize negative impact.

Opportunities for theory-informed decision science in cancer control.

Cancer prevention and control involves navigation of complex clinical decisions, often laden with uncertainty and/or intricate interpersonal dynamics, which have implications for both physical health and quality of life. Cancer decision-making research in recent decades has primarily focused on working to improve the quality of decisions by providing patients with detailed information about their choices and through an increased emphasis in medicine on the importance of shared decision making. This emphasis is reflective of a model of decision making that emphasizes knowledge, options, and deliberative synthesis of information as primary to decision making; yet, decades of research in psychology, decision science, and behavioral economics have taught us that our decisions are not influenced only by our objective knowledge of facts, but by our emotions, by the influence of others, and by biased cognitive processes. We present a conceptual framework for a future of research in decision science and cancer that is informed by decision science theories. Our framework incorporates greater recognition of the interpersonal dynamics of shared decision making, including the biases (including cognitive heuristics and race-based bias) that may affect multiple actors in the decision-making process, and emphasizes study of the interaction between deliberative and affective psychological processes as they relate to decision making. This work should be conducted with an eye toward informing efforts to improve decision making across the cancer care continuum, through interventions that are also informed by theory.
