Activation Versus Change as a Principle Underlying Intervention Strategies to Promote Health Behaviors.

BACKGROUND AND PURPOSE: Interventions are effective in promoting health behavior change to the extent that (a) intervention strategies modify targets (i.e., mechanisms of action), and (b) modifying targets leads to changes in behavior. To complement taxonomies that characterize the variety of strategies used in behavioral interventions, we outline a new principle that specifies how strategies modify targets and thereby promote behavior change. We distinguish two dimensions of targets-value (positive vs. negative) and accessibility (activation level)-and show that intervention strategies operate either by altering the value of what people think, feel, or want (target change) or by heightening the accessibility of behavior-related thoughts, feelings, and goals (target activation). METHODS AND RESULTS: We review strategies designed to promote target activation and find that nudges, cue-reminders, goal priming, the question-behavior effect, and if-then planning are each effective in generating health behavior change, and that their effectiveness accrues from heightened accessibility of relevant targets. We also identify several other strategies that may operate, at least in part, via target activation (e.g., self-monitoring, message framing, anticipated regret inductions, and habits). CONCLUSIONS: The Activation Vs. Change Principle (AVCP) offers a theoretically grounded and parsimonious means of distinguishing among intervention strategies. By focusing on how strategies modify targets, the AVCP can aid interventionists in deciding which intervention strategies to deploy and how to combine different strategies in behavioral trials. We outline a research agenda that could serve to further enhance the design and delivery of interventions to promote target activation.

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.

Support-Giving Is Associated With Lower Systemic Inflammation.

BACKGROUND: Support-giving has emerged as a health-relevant social behavior, such that giving more support is associated with better physical health. However, biological mechanisms by which support-giving and health are linked remain unclear. Whether support-giving uniquely relates to health relative to other psychosocial factors is also an open research question. PURPOSE: Two studies test the hypothesis that support-giving is uniquely (over-and-above other psychosocial factors) related to lower systemic inflammation, a biological correlate of health. METHODS: Cross-sectional associations of support-giving with markers of systemic inflammation (i.e., interleukin-6 [IL-6], C-reactive protein [CRP]) were examined in two independent samples of midlife adults (Study 1, n = 746; Study 2, n = 350). RESULTS: Consistent with hypotheses, giving to more social targets (to family and friends, and also volunteering for various causes), but not receiving support from similar targets, was associated with lower IL-6. In conceptual replication and extension with a different measure of support-giving, higher frequency of support-giving behavior was associated with lower IL-6, even after adjusting for social network size and individual differences in social desirability. There were no associations between support-giving and CRP in either sample. CONCLUSIONS: Future research needs to establish causality and directly test mechanistic pathways, but together, findings reaffirm the health-relevance of support-giving behavior and shed light on a promising biological mechanism by which such effects may occur.

Support-giving behavior and health are linked such that more support-giving is related to better health and longevity for the person giving. How such a link occurs, however, is an open question for research. Two cross-sectional studies test the hypothesis that support-giving behavior relates to lower systemic inflammation, a potential biological pathway linking supportive behavior with health. Results of Study 1 show that giving to more social targets (to family and friends, and also volunteering) is associated with lower inflammation. Receiving support was not associated with inflammation. In a replication and extension, Study 2 shows that a greater frequency of giving is also related to lower systemic inflammation, over and above the size of one's social network and individual differences in reporting socially desirable responses. Although more research is needed to establish whether support-giving causes systemic inflammation to change, the current findings highlight a promising pathway by which support-giving behavior benefits health.

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.

Patient Perspectives on the Risk-Based NLST Outcomes Tool for Lung Cancer Screening.

Researchers at the NCI have developed the Risk-Based NLST Outcomes Tool (RNOT), an online tool that calculates risk of lung cancer diagnosis and death with and without lung cancer screening, and false-positive risk estimates. This tool has the potential to facilitate shared decision making for screening. The objective of this study was to examine how current heavy and former smokers understand and respond to personalized risk estimates from the RNOT. Individuals who were eligible for lung cancer screening and were visiting Walter Reed National Military Medical Center were invited to participate in a semi-structured interview to assess their experiences with and perceptions of the RNOT. Results were analyzed using template analysis. Participants found their risk of lung cancer death to be lower than anticipated and were confused by changes in risk for lung cancer diagnosis with and without screening. Most participants indicated that the RNOT would be helpful in making screening decisions, despite reporting that there was no maximum risk for a false positive that would lead them to forgo lung cancer screening. Participants provided actionable needs and recommendations to optimize this tool. Risk-based screening tools may enhance shared decision making. The RNOT is being updated to incorporate these findings.

Investigating the Efficacy of Genetic, Environmental, and Multifactorial Risk Information When Communicating Obesity Risk to Parents of Young Children.

BACKGROUND: Effectively communicating with parents about children's obesity risk is of critical importance for preventive medicine and public health. PURPOSE: The current study investigates the efficacy of communications focused on two primary causes of obesity: genes and environment. METHODS: We compared parental feeding responses to messages focused on (i) genetics alone, (ii) family environment alone, (iii) genetics-family environment interaction (G × FE), and (iv) no causal message. We also examined whether parental guilt mediates the effect of message type on feeding. Our sample consisted of 190 parents, half mothers and half fathers, of children 3-7 years old. After receiving one of the four types of messages, parents chose foods for their child using the Virtual Reality Buffet measure. Parents responded to questionnaires in the lab and at 1-week follow-up. RESULTS: In the VR Buffet, parents did not feed their children differently in message provision conditions versus control. There were, however, differences among message provision conditions wherein mothers who received any genetic information chose higher-calorie meals in the VR Buffet. At 1-week follow-up, parents who received information about genetics alone reported feeding their child more junk food and fatty meat on self-report food frequency assessments; there were no such differences for sugary beverages, sugary foods, or fast foods. Parental guilt was typically higher for participants who received family environment information alone but did not mediate the relation between information provision and feeding outcomes. CONCLUSIONS: While none of the messages improved feeding above the control condition, GxFE messages were associated with a better overall profile of outcomes. As such, it may be beneficial for messaging for parents about children's obesity risk to include content that reflects the complexity of genetic and environmental contributions to obesity risk.

Temporal and social comparative self-assessments of physical health in young, middle-aged, and young-old adults in the MIDUS study.

This study examined temporal and social comparisons of physical health status. Participants in two waves of the MIDUS cohort ranging in age from young adult to young-old (N = 2,408) rated current, past, and future physical health, as well as peer health. Past health was generally rated as better than current health (particularly among young adults). Young adults expected better future health; young-old adults expected declining health. All groups recalled their health as better than they reported a decade earlier. Middle-aged and young-old respondents expected more decline than they reported ten years later; young adults' ratings were consistent. The two older groups believed they were healthier than same-age peers, whereas younger respondents believed they were less healthy (though as healthy as the other age groups). The nature and trajectories of temporal and social comparisons of physical health across the lifespan suggest the need to examine their consequences for health behaviors.

Association of Spontaneous and Induced Self-Affirmation With Smoking Cessation in Users of a Mobile App: Randomized Controlled Trial.

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.

Measuring Cigarette Smoking Risk Perceptions.

Risk perception is an important construct in many health behavior theories. Smoking risk perceptions are thoughts and feelings about the harms associated with cigarette smoking. Wide variation in the terminology, definition, and assessment of this construct makes it difficult to draw conclusions about the associations of risk perceptions with smoking behaviors. To understand optimal methods of assessing adults' cigarette smoking risk perceptions (among both smokers and nonsmokers), we reviewed best practices from the tobacco control literature, and where gaps were identified, we looked more broadly to the research on risk perceptions in other health domains. Based on this review, we suggest assessments of risk perceptions (1) about multiple smoking-related health harms, (2) about harms over a specific timeframe, and (3) for the person affected by the harm. For the measurement of perceived likelihood in particular (ie, the perceived chance of harm from smoking based largely on deliberative thought), we suggest including (4) unconditional and conditional items (stipulating smoking behavior) and (5) absolute and comparative items and including (6) comparisons to specific populations through (7) direct and indirect assessments. We also suggest including (8) experiential (ostensibly automatic, somatic perceptions of vulnerability to a harm) and affective (emotional reactions to a potential harm) risk perception items. We also offer suggestions for (9) response options and (10) the assessment of risk perception at multiple time points. Researchers can use this resource to inform the selection, use, and future development of smoking risk perception measures. IMPLICATIONS: Incorporating the measurement suggestions for cigarette smoking risk perceptions that are presented will help researchers select items most appropriate for their research questions and will contribute to greater consistency in the assessment of smoking risk perceptions among adults.

Evidence that perceptions of and tolerance for medical ambiguity are distinct constructs: An analysis of nationally representative US data.

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.

Effect of instrumental support on distress among family caregivers: Findings from a nationally representative study.

BACKGROUND AND OBJECTIVE: A priority focus on palliative and supportive care is helping the 43.5 million caregivers who care for individuals with serious illness. Lacking support may lead to caregiver distress and poorer care delivery to patients with serious illness. We examined the potential of instrumental support (assistance with material and task performance) to mitigate distress among caregivers. METHOD: We analyzed data from the nationally representative Health Information National Trends Survey (HINTS V2, 2018). Informal/family caregivers were identified in HINTS V2 if they indicated they were caring for or making healthcare decisions for another adult with a health problem. We used the PROMIS® instrumental support four-item short-form T-scores and the Patient Health Questionnaire (PHQ-4) for distress. We examined multivariable linear regression models for associations between distress and instrumental support, adjusted for sampling weights, socio-demographics, and caregiving variables (care recipient health condition(s), years caregiving (≥2), relationship to care recipient, and caregiver burden). We examined interactions between burden and instrumental support on caregiver distress level. RESULTS: Our analyses included 311 caregivers (64.8% female, 64.9% non-Hispanic White). The unweighted mean instrumental support T-score was 50.4 (SD = 10.6, range = 29.3-63.3); weighted mean was 51.2 (SE = 1.00). Lower instrumental support (p < 0.01), younger caregiver age (p < 0.04), higher caregiving duration (p = 0.008), and caregiver unemployment (p = 0.006) were significantly associated with higher caregiver distress. Mean instrumental support scores by distress levels were 52.3 (within normal limits), 49.4 (mild), 48.9 (moderate), and 39.7 (severe). The association between instrumental support and distress did not differ by caregiver burden level. CONCLUSIONS: Poor instrumental support is associated with high distress among caregivers, suggesting the need for palliative and supportive care interventions to help caregivers leverage instrumental support.

Parent Instrumentality for Adolescent Eating and Activity.

BACKGROUND: Parent-adolescent interactions have health implications for adolescents. Parents can be instrumental to healthy eating by purchasing fruits and vegetables or refraining from purchasing hedonic (low nutrient, high energy-dense) foods. Parents can be instrumental to healthy activity by modeling exercise behavior or discouraging sedentary activities. PURPOSE: This research leverages theory on goal pursuit within relationships to investigate whether parents are instrumental to adolescents' eating and activity. METHODS: Using a national sample of 1,556 parent-adolescent dyads, we conducted dyadic analyses to examine whether parent instrumentality (both parent-perceived and adolescent-perceived) for healthy behaviors was associated with adolescent engagement in those behaviors. We examined whether the link between parent instrumentality and adolescent BMI was mediated by parent instrumentality. We also explored whether parent instrumentality was associated with parent behaviors and parent BMI. RESULTS: Greater adolescent-perceived parent instrumentality was associated with greater fruit and vegetable consumption and physical activity, and lower sedentariness. Parent-perceived parent instrumentality was associated with greater adolescent fruit and vegetable consumption, less hedonic eating, and more activity. Mediation modeling suggests that adolescent BMI is partially attributable to parent instrumentality for activity. Instrumental parents also engage in healthier behaviors, some of which in turn are associated with lower parent BMI. CONCLUSIONS: Findings have implications for the promotion of healthy eating and activity patterns among adolescents. Parental instrumentality for behavior may be an important target for interventions to improve adolescent health, and interventions may be most successful in facilitating adolescent behavior change if they target both parent- and adolescent-perceived parent instrumentality.

Trajectories of Current and Predicted Satisfaction With One's Life Following a Cancer Diagnosis.

Background: Poor physical and mental health is common among cancer survivors, but little is known about how cancer influences life satisfaction and expectations about one's future, both of which may subsequently influence health decisions and outcomes. Purpose: The current study examined how a cancer diagnosis influences current and predicted future life satisfaction in seven domains, including family, finances, work, and health. Methods: We leveraged data from three waves of the Midlife in the United States study (N = 6,389) and examined the relation between new and past cancer diagnoses on satisfaction using generalized estimating equations. We also compared participants' predicted satisfaction to the actual satisfaction they reported at later waves of data collection, and examined whether concordance between the two differed by cancer history. Results: A cancer diagnosis was associated with a decline in satisfaction about one's present health and sex life, ps < .05, but satisfaction with all other domains remained steady or improved. In contrast, predictions about the future became and remained less optimistic than the predictions of those without cancer across all life domains except relationships with children, ps < .05. Within-subjects comparisons of predicted and actual satisfaction suggest those without a cancer history were optimistic in their predictions across all life domains except health whereas survivors were more accurate in their predictions. Conclusions: Given the many ways in which expectations about the future can influence decision making, behavior, and health, survivors' attenuated optimistic outlooks may influence their health and well-being.

Effects of Fruit and Vegetable Feeding Messages on Mothers and Fathers: Interactions Between Emotional State and Health Message Framing.

BACKGROUND: There is a pressing need to craft optimal public health messages promoting healthy feeding behaviors among parents. How these messages influence such feeding decisions are affected by multiple interactive factors including emotional states, message framing, and gender, but these factors have not been studied in the domain of parents' feeding of their children. PURPOSE: To evaluate the role of message framing, emotional state, and parent gender on feeding choices that parents make for their children. METHODS: In 2016-2017, 190 parents (126 mothers) of 4- to 7-year-old children were randomly assigned to an anger or fear emotion induction and read either a gain- or loss-framed message about the importance of children's fruit and vegetable (FV) consumption prior to choosing foods for their child from a virtual reality buffet. RESULTS: Mothers in an angry state who received a gain-framed message chose relatively more FV for their child in the virtual buffet, F(3, 180) = 4.77, p = .027. However, fathers in this group did not feed more FV, but rather reported greater intention to improve future FV feeding, F(3, 180) = 4.91, p = .028. CONCLUSIONS: Providing gain-framed messages to parents, particularly mothers, in an anger state may be most effective for motivating healthy dietary choices for children.

Reconceptualizing Self-Affirmation With the Trigger and Channel Framework: Lessons From the Health Domain.

Self-affirmation-a theory-based technique to affirm the adaptive adequacy of the self-can promote positive behavior change and adaptive outcomes, although effects are variable. We extend a novel framework (Trigger and Channel), proposing three conditions that facilitate self-affirmation-induced behavior change: (a) presence of psychological threat, (b) presence of resources to foster change, and (c) timeliness of the self-affirmation with respect to threat and resources. Using health behavior as a focus, we present meta-analytic evidence demonstrating that when these conditions are met, self-affirmation acts as a psychological trigger into a positive channel of resources that facilitate behavior change. The presence of a timely threat and the availability of timely resources independently predicted larger self-affirmation effects on behavior change, and the two interacted synergistically to predict still larger effects. The results illustrate the conditionality of self-affirmation effects and offer guidelines for when, where, and for whom self-affirmation will be most effective.

Social support, loneliness, eating, and activity among parent-adolescent dyads.

We examined associations of social support and loneliness with eating and activity among parent-adolescent dyads (N = 2968) using actor-partner interdependence modeling. Loneliness had several actor associations with health behaviors (adolescents: less physical activity [PA], p < .001, more sedentariness, p < .001; parents: less fruit/vegetable consumption [FVC], p = .029, more hedonic food consumption [HFC], p = .002, and sedentariness, p < .001), but only one dyadic association (adolescent loneliness with less parent FVC, p = .039). Visible support was associated with less HFC, p < .001, and sedentariness, p < .001, but less FVC, p = .008, among adolescents. Invisible support was associated with less HFC, p = .003, but also less PA, p = .028, among adolescents. Both support types were associated with less HFC among parents, p < .001, but invisible support was also associated with less FVC, p = .029, and PA, p = .012, and more sedentariness, p = .013, among parents. When examining health behavior among parents and adolescents, it may be important to consider social support (but perhaps not loneliness) at a dyadic level.

Interventions to Engage Affective Forecasting in Health-Related Decision Making: A Meta-Analysis.

Background: People often use affective forecasts, or predictions about how a decision will make them feel, to guide medical and health decision making. However, these forecasts are susceptible to biases and inaccuracies that can have consequential effects on decision making and health. Purpose: A meta-analysis was performed to determine the effectiveness of intervening to address affective forecasting as a means of helping patients make better health-related choices. Methods: We included between-subjects experimental and intervention studies that targeted variables related to affective forecasting (e.g., anticipated regret, anticipated affect) as a means of changing health behaviors or decisions. We determined the overall effect of these interventions on targeted affective constructs and behavioral outcomes, and whether conceptual and methodological factors moderated these effects. Results: A total of 133 independent effect sizes were identified from 37 publications (N = 72,020). Overall, affective forecasting interventions changed anticipated regret, d = 0.24, 95% confidence interval (CI) (0.15, 0.32), p < .001, behavior, d = 0.29, 95% CI (0.13, 0.45), p < .001, and behavioral intentions, d = 0.19, 95% CI (0.11, 0.28), p < .001, all measured immediately postintervention. Interventions did not change anticipated positive and negative affect, and effects on intentions and regret did not extend to follow-up time points, ps > .05. Generally, effects were not moderated by conceptual model, intervention intensity, or behavioral context. Conclusions: Affective forecasting interventions had a small consistent effect on behavioral outcomes regardless of intervention intensity and conceptual framework, suggesting such constructs are promising intervention targets across several health domains.

Variation in health beliefs across different types of cervical screening non-participants.

Understanding factors associated with different types of cancer screening non-participation will help with the development of more targeted approaches for improving informed uptake. This study explored patterns of general health beliefs and behaviour, and cancer-specific beliefs across different types of cervical screening non-participants using the Precaution Adoption Process Model (PAPM). A population-representative sample of women in Britain completed a home-based survey in 2016. Women classified as non-participants (n = 839) completed additional questions about health beliefs. Some general health beliefs and behaviours, as well as cancer-specific beliefs, were associated with particular types of non-participation. For example, those who scored higher on fatalism were more likely to be unaware of screening (OR = 1.74, 95%CI: 1.45-2.08) or unengaged with screening (OR = 1.57, CI: 1.11-2.21). Women with greater deliberative risk perceptions were less likely to be unengaged with screening (OR = 0.74 CI: 02.55-0.99) and less likely to have decided against screening (OR = 0.71, CI: 0.59-0.86). Women who had seen a general practitioner in the last 12 months were less likely to be unaware (OR = 0.49, CI: 0.35-0.69), and those reporting cancer information avoidance were more likely to be unengaged with screening (OR = 2.25, CI: 1.15-4.39). Not wanting to know whether one has cancer was the only factor associated with all types of non-participation. Interventions to raise awareness of screening should include messages that address fatalistic and negative beliefs about cancer. Interventions for women who have decided not to be screened could usefully include messages to ensure the risk of cervical cancer and the relevance and benefits of screening are well communicated.
