RESUMO

Social norms messages may promote information seeking, especially when the norms refer to a group with which a person identifies. We hypothesized that tailored social norms messages would increase COVID-19 testing willingness and intentions. College students (n = 203, 75% female, 87% White) were randomly assigned to one of four conditions in a 2 (Descriptive norms: Relevant vs. Irrelevant to COVID-19 testing) x 2 (Tailoring: Specific vs. General group information) experimental design. Participants reported COVID-19 testing willingness and intentions, perceived injunctive norms, and identification and connectedness with the group in the message. Although neither the norm nor tailoring manipulation worked as intended, participants who perceived greater message tailoring and injunctive norms reported greater willingness and intentions, with no effect of perceived descriptive norms on either outcome. Tailored messages as well as messages promoting injunctive norms may promote information seeking across health contexts, thereby enabling more informed decisions.

RESUMO

Whether to undergo genome sequencing in a clinical or research context is generally a voluntary choice. Individuals are often motivated to learn genomic information even when clinical utility-the possibility that the test could inform medical recommendations or health outcomes-is low or absent. Motivations to seek one's genomic information can be cognitive, affective, social, or mixed (e.g., cognitive and affective) in nature. These motivations are based on the perceived value of the information, specifically, its clinical utility and personal utility. We suggest that motivations to learn genomic information are no different from motivations to learn other types of personal information, including one's health status and disease risk. Here, we review behavioral science relevant to motivations that may drive engagement with genome sequencing, both in the presence of varying degrees of clinical utility and in the absence of clinical utility. Specifically, we elucidate 10 motivations that are expected to underlie decisions to undergo genome sequencing. Recognizing these motivations to learn genomic information will guide future research and ultimately help clinicians to facilitate informed decision making among individuals as genome sequencing becomes increasingly available.

RESUMO

Uncertainty is prevalent in various health contexts. It is imperative to understand how health-related uncertainty can impact individuals' healthcare experiences and health decision making. The purpose of the present paper is to provide five overarching recommendations from an interdisciplinary team of experts to address gaps in the literature on health-related uncertainty. We present a case study of health-related uncertainty within the specific context of alcohol use to demonstrate these gaps and provide context for the recommendations. The five recommendations concerning health-related uncertainty include: (1) use common, consistent terminology to discuss uncertainty, (2) clarify measures of individual differences in response to uncertainty, (3) increase research on uncertainty and affect, (4) investigate the impact of the channel through which uncertainty is communicated, and (5) develop theory-driven interventions to improve uncertainty management. We conclude by reviewing health contexts in which health-related uncertainty exists and note how our recommendations complement existing reviews and data.

RESUMO

Information about the health effects of alcohol consumption can be ambiguous (i.e., lacking in reliability, credibility, or adequacy) and thus may promote maladaptive health behavior. Guided by Construal Level Theory and a conceptual taxonomy of uncertainty in health care, we tested the hypothesis that manipulating construal level would promote adaptive responses to ambiguous health information. We examined the effects of ambiguous health information about alcohol on health cognitions, message responses, and intentions, as well as whether manipulating construal moderated these effects. Alcohol users (n = 135, Mage = 20.15, 68.9% female) were randomly assigned to either a high-level or low-level construal task and then to read either an ambiguous or unambiguous health communication about the health effects of alcohol. Participants responded similarly to ambiguous health information as they did to unambiguous health information and participants in a high-level construal did not generally report differences compared with those in a low-level construal. Findings suggest that ambiguous health information might not always lead to maladaptive effects. More research is needed to examine moderators of the relationship between ambiguous health information and health outcomes, as well as to understand how and when using construal manipulations are effective in different health contexts.

RESUMO

BACKGROUND: Information avoidance tendencies have been found to be associated with lower intentions to pursue medically actionable genomic sequencing results, but less so among individuals who engage more in spontaneous self-affirmation. Yet these results were obtained with a largely non-Hispanic White, high-SES cohort. PURPOSE: To assess these variables, their magnitude, and their associations in an African-descent cohort as part of the same ClinSeq® exome sequencing program. METHODS: Participants reported levels of spontaneous self-affirmation, information avoidance, and intentions to receive three types of results - medically actionable, non-medically actionable, and carrier status as part of a baseline survey. RESULTS: Relative to the original, non-Hispanic White cohort, those in the African-descent cohort had higher levels of spontaneous self-affirmation and lower intentions of learning about carrier genomic results; they reported comparable levels of information avoidance and intentions to receive other results. Information avoidance was negatively associated with intention to receive non-actionable results in the African-descent cohort, as found in the initial cohort, with no moderating effect of spontaneous self-affirmation. Information avoidance, spontaneous self-affirmation, and their interaction were not associated with intentions to receive actionable results (contrary to findings in the initial cohort), or carrier results. CONCLUSIONS: Individuals of African descent may engage in relatively more spontaneous self-affirmation, and do not appear to engage in more information avoidance. Their information avoidance tendencies were associated with pursuit of non-actionable sequencing results, with no moderating effect of self-affirmation, and were not associated with pursuit of actionable results or carrier results.

RESUMO

Perceiving ambiguity in health information-that is, uncertainty elicited from believing information lacks credibility, reliability, or adequacy-is typically associated with pessimistic appraisals (e.g., high perceived disease risk) and behavioral avoidance. We examined the effect of ambiguous health information about COVID-19 on health cognitions and vaccination intentions, and tested a "normalized-uncertainty" intervention. Two studies with identical methodology (online adult sample: n = 299, undergraduate sample: n = 150) were conducted in March to April 2020. Participants were randomly assigned to read one of three health messages about COVID-19 that emphasized what was currently unknown (ambiguity condition), what was currently unknown but that scientific uncertainty is expected (intervention condition), or what was currently known (control condition). The ambiguity condition led to greater perceived ambiguity than the control condition and perceived ambiguity in the intervention condition was comparable to the ambiguity condition. There were few differences in health cognitions, and no differences in vaccination intentions, when examining pairwise comparisons across the three conditions. Correlational analyses collapsing across condition indicated evidence of pessimistic appraisal but not behavioral avoidance among individuals who perceived greater ambiguity. Future research should examine longer, more detailed normalized-uncertainty interventions.

RESUMO

BACKGROUND: Understanding multiple components of risk perceptions is important because perceived risk predicts engagement in prevention behaviors. PURPOSE: To examine how multiple components of risk perceptions (perceived magnitude of and worry about risk, prioritization of the management of one's risk) changed following genetic counseling with or without test reporting, and to examine which of these components prospectively predicted improvements in sun-protection behavior 1 year later. METHODS: A prospective, nonrandomized study design was used. Participants were 114 unaffected members of melanoma-prone families who (i) underwent genetic testing for a CDKN2A/p16 mutation (n = 69) or (ii) were at comparably elevated risk based on family history and underwent genetic counseling but not testing (no-test controls, n = 45). Participants reported risk perception components and sun-protection behavior at baseline, immediately following counseling, and 1 month and 1 year after counseling. RESULTS: Factor analysis indicated three risk components. Carriers reported increased perceived magnitude and priority of risk, but not cancer worry. No-test controls showed no changes in any risk perception. Among noncarriers, priority of risk remained high at all assessments, whereas magnitude of risk and cancer worry decreased. Of the three risk components, greater priority of risk uniquely predicted improved self-reported sun protection 1 year post-counseling. CONCLUSIONS: Priority of risk (i) seems to be a component of risk perceptions distinguishable from magnitude of risk and cancer worry, (ii) may be an important predictor of daily prevention behavior, and (iii) remained elevated 1 year following genetic counseling only for participants who received a positive melanoma genetic test result.

RESUMO

BACKGROUND & PURPOSE: Primary prevention of COVID-19 has focused on encouraging compliance with specific behaviors that restrict contagion. This investigation sought to characterize engagement in these behaviors in U.S. adults early during the pandemic and to build explanatory models of the psychological processes that drive them. METHODS: US adults were recruited through Qualtrics Research Panels (N = 324; 55% female; Mage = 50.91, SD = 15.98) and completed 10 days of online reports of emotion, COVID-19 perceived susceptibility and worry, and recommended behaviors (social distancing, hand washing, etc.). Factor analysis revealed behaviors loaded on two factors suggesting distinct motivational orientations: approach and avoidance. RESULTS: Changes in approach and avoidance behaviors over the 10 days indicated large individual differences consistent with three types of participants. Discrete emotions, including fear, guilt/shame, and happiness were associated with more recommended behaviors. Fear and COVID-19 worry indirectly influenced each other to facilitate more behavioral engagement. While emotions and worry strongly predicted individual differences in behavior across the 10 days, they did not predict as well why behaviors occurred on one day versus another. CONCLUSIONS: These findings suggest how daily affective processes motivate behavior, improving the understanding of compliance and efforts to target behaviors as primary prevention of disease.

RESUMO

Although romantic couple concordance has been demonstrated across a wide array of health behaviors, little research has examined dyadic concordance in health beliefs. This study examined the extent to which cohabitating romantic dyads' attitudes and beliefs coincide (i.e., dyadic concordance) in addition to how well they predict intentions to learn genomic sequencing results. The actor-partner interdependence model was applied to cross-sectional data from 81 dyads in an exome sequencing study who were surveyed about their risk perceptions, worry, information avoidance, attitudes, and intentions toward learning carrier results. Information avoidance tendencies were positively correlated between partners, but there was low concordance on other beliefs. Individuals' attitudes and information avoidance predicted their own intentions to learn results. Additionally, partners' information avoidance tendencies predicted their partner's intentions to learn results. Future research should explore mechanisms through which one's partner's information avoidance may affect one's own intentions and behaviors.

RESUMO

BACKGROUND: Links among poor sleep and cancer risk behaviors have been largely overlooked in the context of cancer prevention and behavioral medicine. The goal of this scoping review was to determine the extent and nature of experimental studies conducted with healthy adult populations that tested the associations among poor sleep and cancer risk behaviors. METHOD: Electronic databases and major sleep journals were searched to identify experimental studies in healthy adult samples published through January 2018. Studies examined associations among eight pairings of manipulated behaviors and outcomes ("independent variable (IV)-outcome pairs"): the impact of sleep manipulations on physical activity (PA), diet, alcohol consumption, and tobacco use outcomes; and the impact of PA, diet, alcohol consumption, and tobacco use manipulations on sleep outcomes. Studies were characterized in terms of sample characteristics; study design; IV type, dose, and duration; and outcome measurement and duration. RESULTS: Abstracts of 5697 papers and 345 full texts were screened. Eighty-eight studies describing 125 comparisons met inclusion criteria. Only two studies tested the association between tobacco use and sleep; none tested whether sleep influenced alcohol consumption. Sample sizes were typically small, most studies used crossover designs, and studies tended to include younger and more male participants. Within each IV-outcome pair, there was substantial heterogeneity in how behaviors were manipulated, outcome measurement, and type of control group. Few studies assessed mechanisms. CONCLUSION: There is a need for larger experimental studies with more representative samples. Overall, heterogeneity and limitations in study designs make it difficult to synthesize evidence across studies.

RESUMO

BACKGROUND: Internet-based risk assessment tools offer a potential avenue for people to learn about their cancer risk and adopt risk-reducing behaviors. However, little is known about whether internet-based risk assessment tools adhere to scientific evidence for what constitutes good risk communication strategies. Furthermore, their quality may vary from a user experience perspective. OBJECTIVE: This study aims to understand the extent to which current best practices in risk communication have been applied to internet-based cancer risk assessment tools. METHODS: We conducted a search on August 6, 2019, to identify websites that provided personalized assessments of cancer risk or the likelihood of developing cancer. Each website (N=39) was coded according to standardized criteria and focused on 3 categories: general website characteristics, accessibility and credibility, and risk communication formats and strategies. RESULTS: Some best practices in risk communication were more frequently adhered to by websites. First, we found that undefined medical terminology was widespread, impeding comprehension for those with limited health literacy. For example, 90% (35/39) of websites included technical language that the general public may find difficult to understand, yet only 23% (9/39) indicated that medical professionals were their intended audience. Second, websites lacked sufficient information for users to determine the credibility of the risk assessment, making it difficult to judge the scientific validity of their risk. For instance, only 59% (23/39) of websites referenced the scientific model used to calculate the user's cancer risk. Third, practices known to foster unbiased risk comprehension, such as adding qualitative labels to quantitative numbers, were used by only 15% (6/39) of websites. CONCLUSIONS: Limitations in risk communication strategies used by internet-based cancer risk assessment tools were common. By observing best practices, these tools could limit confusion and cultivate understanding to help people make informed decisions and motivate people to engage in risk-reducing behaviors.

RESUMO

BACKGROUND: Most smokers attempt to stop using cigarettes numerous times before successfully quitting. Cigarette cravings may undermine perceived competence to quit and thus constitute psychological threats to the individual's self-concept. Self-affirmation may promote smoking cessation by offsetting these threats. OBJECTIVE: This study examines whether self-affirmation is associated with smoking cessation in the context of a cessation app. Two types of self-affirmation are examined: tendency to spontaneously self-affirm, and self-affirmation inductions added to a publicly available smoking cessation app (Smoke-Free Quit Smoking Now). In addition, this study explores whether optimism and emotional states (happiness, anger, anxiousness, hopefulness, sadness) predict smoking cessation. METHODS: All users who met the inclusion criteria, provided consent to participate, and completed a baseline assessment, including all individual difference measures, were randomized to 1 of 4 conditions. Half of the participants were randomly assigned to complete a self-affirmation induction upon study entry. Orthogonally, half of the participants were randomly assigned to receive self-affirming text notifications during their quit attempt or to receive conventional notifications. The induction and the text notifications were fully automated, and all data were collected through self-assessments in the app. Self-reported smoking cessation was assessed 1 month and 3 months following study entry. RESULTS: The study enrolled 7899 participants; 647 completed the 1-month follow-up. Using an intent-to-treat analysis at the 1-month follow-up, 7.2% (569/7899) of participants self-reported not smoking in the previous week and 6.4% (503/7899) self-reported not smoking in the previous month. Greater tendency to spontaneously self-affirm predicted a greater likelihood of cessation (P<.001) at 1 month after controlling for smoking-related variables. Neither self-affirmation induction influenced cessation. In addition, spontaneous self-affirmation did not moderate the relationship between self-affirmation inductions and cessation. Greater baseline sadness was associated with a lower likelihood of reporting successful cessation. Optimism predicted past-week cessation at the 1-month follow-up, and both happiness and anger predicted past-month cessation at the 1-month follow-up; however, none of these potential predictors moderated the relationship between self-affirmation conditions and successful cessation. CONCLUSIONS: Spontaneous self-affirmation may be an important psychological resource for managing threats to self-concept during the smoking cessation process. Sadness may hinder quit attempts. Future research can explicate how spontaneous versus induced self-affirmation can promote smoking cessation and examine boundary conditions for the effectiveness of disseminated self-affirmation interventions.

RESUMO

PURPOSE: This study investigated whether genetic counseling and test reporting for the highly penetrant CDKN2A melanoma predisposition gene promoted decreases in sun exposure. METHODS: A prospective, nonequivalent control group design compared unaffected participants (N = 128, Mage = 35.24, 52% men) from (1) families known to carry a CDKN2A pathogenic variant, who received counseling about management recommendations and a positive or negative genetic test result and (2) no-test control families known not to carry a CDKN2A pathogenic variant, who received equivalent counseling based on their comparable family history. Changes in daily ultraviolet radiation (UVR) exposure (J/m2), skin pigmentation (melanin index), and sunburns between baseline and one year following counseling were compared among carriers (n = 32), noncarriers (n = 46), and no-test control participants (n = 50). RESULTS: Both carriers and no-test control participants exhibited a decrease one year later in daily UVR dose (B = -0.52, -0.33, p < 0.01). Only carriers exhibited a significant decrease in skin pigmentation at the wrist one year later (B = -0.11, p < 0.001), and both carriers and no-test control participants reported fewer sunburns than noncarriers (p < 0.05). Facial pigmentation did not change for any group. Noncarriers did not change on any measure of UVR exposure. CONCLUSIONS: These findings support the clinical utility of disclosing CDKN2A test results and providing risk management education to high-risk individuals.

RESUMO

BACKGROUND: Medical information is often conflicting and consequently perceived as ambiguous. There are individual differences both in how much people perceive ambiguity and in their tolerance for such ambiguity. Little is known about how these constructs are related to each other and with other beliefs. OBJECTIVE: To examine the association between (a) perceived medical ambiguity, (b) tolerance for medical ambiguity and (c) their associations with various medical and cancer-specific judgement and decision-making correlates. METHOD AND PARTICIPANTS: We conducted secondary data analyses using the cross-sectional, nationally representative Health Information National Trends Survey 4, Cycle 4 (n = 3,433, 51.0% female, Mage  = 46.5). Analyses statistically controlled for age, sex, race, education and health-care coverage. MAIN VARIABLES STUDIED: Perceived medical ambiguity, tolerance for medical ambiguity, cancer perceptions, health-care experiences and preferences, and information-seeking styles and beliefs. RESULTS: Perceived medical ambiguity and tolerance for medical ambiguity were statistically independent. Higher perceived ambiguity was associated with lower perceived cancer preventability, lower reliance on doctors, lower perceived health and information-seeking self-efficacy, lower perceived quality of the cancer information-seeking process, and greater cancer information avoidance. Lower tolerance for ambiguity was associated with lower cancer worry, lower trust in doctors, lower likelihood of seeking health information, and lower engagement in medical research. DISCUSSION AND CONCLUSIONS: Perceived medical ambiguity and tolerance for medical ambiguity seem to be distinct constructs. Findings have implications for how people make medical decisions when they perceive and prefer to avoid conflicting medical information.

RESUMO

Many cigarette smokers make multiple attempts to quit before they are successful. Implicit theories of smoking (ITS)-beliefs about whether smoking behavior is something that is changeable (incremental belief) or fixed (entity belief)-may play a role in quitting. Four iterations of the cross-sectional, nationally-representative Health Information National Trends Survey (HINTS) were used in logistic regression analyses to examine how smokers' ITS relates to (1) attempts to quit in the past 12 months; (2) considering quitting in the next 6 months; and (3) the interaction between ITS and past quit attempts on considering quitting. Greater incremental beliefs were not significantly associated with having tried to quit in the past year (ß = .27, p = .055); however, greater incremental beliefs were associated with greater likelihood of considering quitting in the next 6 months (ß = .22, p = .04). Past quit attempts did not moderate the association between ITS and considering quitting (ß = .59, p = .10). Results suggest that incremental beliefs are associated with increased intentions to quit.

RESUMO

We examined what proportion of the U.S. population with no personal cancer history reported receiving either genetic counseling or genetic testing for cancer risk, and also the association of these behaviors with cancer risk perceptions. We used data from the 2015 National Health Interview Survey. Objective relative risk scores for breast (women) and colorectal (men and women) cancer risk were generated for individuals without a personal history of cancer. Participants' risk perceptions were compared with their objective relative risk. Of 12,631 women, 1.2% reported receiving genetic counseling and 0.8% genetic testing for hereditary breast cancer risk. Of 15,085 men and women, 0.8% reported receiving genetic counseling and 0.3% genetic testing for hereditary colorectal cancer risk. Higher breast cancer risk perception was associated with genetic counseling (OR: 4.31, 95%CI: 2.56, 7.26) and testing (OR: 3.56, 95%CI: 1.80, 7.03). Similarly, higher perception of colorectal cancer risk was associated with genetic counseling (OR: 5.04, 95%CI: 2.57, 9.89) and testing (OR: 5.92, 95%CI: 2.40, 14.63). A higher proportion of individuals with colorectal cancer risk perceptions concordant with their objective risk (vs. discordant) had undergone genetic counseling or testing for colorectal cancer risk. Concordant risk perceptions for breast cancer were not associated with breast cancer genetic counseling or testing. Given frequent dialogue about implementing population level programs involving genetic services for cancer risk, policy makers and investigators should consider the role of risk perceptions in the effectiveness and design of such programs and potential strategies for addressing inaccuracies in risk perceptions.

RESUMO

Self-affirmation interventions can reduce defensive responses to threats to the self, but have had limited reach to the general population. We sought to create an effective and feasible version of the Kindness Questionnaire self-affirmation intervention for use on a mobile device outside the traditional university laboratory setting and by non-student participants. In an online experiment, 603 cigarette smokers (Mage= 37.5 years, SD = 10.2) were randomly assigned to one of six conditions in a 2 (Self-Affirmation: Self-Affirmation, No Self-Affirmation Control) × 3 (Example Type: Written, Imagined, No Examples) fully-crossed design. Participants read a message about the health harms of smoking. None of the self-affirmation variations were effective or feasible: the self-affirmation showed null effects on the primary outcomes of message acceptance, perceived message effectiveness, and reactance. It also backfired by reducing intentions to quit smoking and risk perceptions. Participants spent little time reading the health message, and those in the written self-affirmation condition infrequently provided detailed responses. Translating interventions developed and tested for efficacy in laboratory settings to "real-world" settings is necessary but challenging.

RESUMO

PurposeAs genome science advances, people receiving personalized genetic information may receive reinterpretations of pathogenicity. Little is known about responses to adjusted results. We examined how reinterpretations might affect attitudes about genetic testing and intentions to share results with family.MethodsData were collected from high-socioeconomic-status participants (n = 58) in a genome sequencing study. Twenty-nine originally learned they were carriers of Duarte variant galactosemia, based on a variant that was reclassified as benign. Positive testers (n = 19) had a newly identified causative variant and remained carriers. Negative testers (n = 10) learned they were no longer carriers. Twenty-nine controls were carriers for a disease of comparable severity with no reclassification. Participants completed baseline, immediate, and 3-month follow-up surveys.ResultsApproximately 80% of participants demonstrated complete or partially accurate recall of their results and reported positive or neutral reactions to their result and about genetic information more generally. Positive testers reported lower intentions to share the change in their result with family. Controls reported the lowest intentions to learn future results. There were no significant group differences or changes over time in perceived ambiguity or negative emotions.ConclusionThe results suggest that high-socioeconomic-status participants understand reinterpretations conferring a neutral change or a change from carrier to noncarrier status. Participants' responses to changes in carrier results for a low-risk condition indicated minimal adverse effects.

While the general efficacy of skin cancer interventions have been reviewed, employing the cancer control continuum would be useful to identify research gaps at specific cancer control points. We characterized the intervention evidence base for specific behavioral targets (e.g., tanning, sun protection, screening) and clinically related targets (e.g., sunburn, skin exams, cancers) at each point in the cancer control continuum. The review included articles published from 1/1/2000-6/30/15 that had an experimental design and targeted behavioral intervention in skin cancer (e.g., specific behaviors or clinically related targets). The search yielded 86 articles, including seven dissemination studies. Of the 79 non-dissemination studies, 57 exclusively targeted primary prevention behaviors, five exclusively targeted screening, 10 targeted both detection and prevention, and eight addressed cancer survivorship. Among prevention studies (n=67), 29 (43%) targeted children and 38 (57%) targeted adults. Of the 15 screening studies, nine targeted high-risk groups (e.g., men aged ≥50 years) and six targeted the general population. Although research has focused on skin cancer prevention, empirically validated interventions are still needed for youth engaged in indoor tanning and for behavioral interventions to pursue change in clinically relevant targets. Research must also address detection among those at highest risk for skin cancer, amelioration of emotional distress attendant to diagnosis and treatment, and survivorship concerns. We discuss essential qualities and opportunities for intervention development and translational research to inform the field.

RESUMO

The National Cancer Institute's Skin Cancer Intervention across the Cancer Control Continuum model was developed to summarize research and identify gaps concerning skin cancer interventions. We conducted a mapping review to characterize whether behavioral interventions addressing skin cancer prevention and control from 2000 to 2015 included (1) technology, (2) environmental manipulations (policy and/or built environment), and (3) a theoretical basis. We included 86 studies with a randomized controlled or quasi-experimental design that targeted behavioral intervention in skin cancer for children and/or adults; seven of these were dissemination or implementation studies. Of the interventions described in the remaining 79 articles, 57 promoted only prevention behaviors (e.g., ultraviolet radiation protection), five promoted only detection (e.g., skin examinations), 10 promoted both prevention and detection, and seven focused on survivorship. Of the 79 non-dissemination studies, two-thirds used some type of technology (n=52; 65.8%). Technology specific to skin cancer was infrequently used: UVR photography was used in 15.2% of studies (n=12), reflectance spectroscopy was used in 12.7% (n=10), and dermatoscopes (n=1) and dosimeters (n=2) were each used in less than 3%. Ten studies (12.7%) targeted the built environment. Fifty-two (65.8%) of the studies included theory-based interventions. The most common theories were Social Cognitive Theory (n=20; 25.3%), Health Belief Model (n=17; 21.5%), and the Theory of Planned Behavior/Reasoned Action (n=12; 15.2%). Results suggest that skin cancer specific technology and environmental manipulations are underutilized in skin cancer behavioral interventions. We discuss implications of these results for researchers developing skin cancer behavioral interventions.
