Moderators of the Effects of mySmartSkin, a Web-Based Intervention to Promote Skin Self-examination and Sun Protection Among Individuals Diagnosed With Melanoma

Background Identifying the characteristics of persons who benefit more from behavioral interventions can help health care providers decide which individuals should be offered particular interventions because this is the subgroup of persons who are more likely to derive greater benefit from the intervention and refine the underlying constructs of the model guiding the intervention. Purpose This study evaluated possible demographic, medical, knowledge and attitudinal, and psychosocial variables that may moderate the impact of an online intervention, called mySmartSkin (MSS), on engagement in skin self-examination (SSE) and sun protection behaviors among melanoma survivors. Methods Participants completed a baseline survey and were then randomized to the MSS condition or usual care. Follow-up surveys were completed by participants at 8-, 24-, and 48-week postrandomization. Results A greater impact of MSS on SSE was illustrated among participants with more phenotypic skin cancer risk factors and participants reporting lower baseline self-efficacy in conducting SSE. A more favorable response of MSS on sun protection behaviors was shown when initial knowledge about abnormal lesions and sun protection barriers were high. Greater use of MSS and more favorable evaluations of it were also associated with higher intervention response. Conclusions Future studies seeking to improve SSE and sun protection among melanoma survivors might benefit from focusing on survivors who report more skin cancer risk factors, lower self-efficacy in conducting SSE, less knowledge about what abnormal skin lesions look like, more perceived barriers to sun protection behaviors, and less worry about recurrence and cancer-related distress.

Choice and the Placebo Effect: A Meta-analysis

Background Choice has been proposed as a method of enhancing placebo effects. However, there have been no attempts to systematically evaluate the magnitude, reliability, and moderators of the influence of choice on the placebo effect. Purpose To estimate the effect size of choice on the placebo effect and identify any moderators of this effect. Methods Web of Science, PsycINFO, EMBASE, and PubMed were systematically searched from inception to May 2021 for studies comparing placebo treatment with any form of choice over its administration (e.g., type, timing) to placebo treatment without choice, on any health-related outcome. Random-effects meta-analysis was then used to estimate the effect size associated with the influence of choice on the placebo effect. Meta-regression was subsequently employed to determine the moderating effect of factors such as type of choice, frequency of choice, and size of the placebo effect without choice. Results Fifteen independent studies (N = 1,506) assessing a range of conditions, including pain, discomfort, sleep difficulty, and anxiety, met inclusion criteria. Meta-analysis revealed that choice did significantly enhance the placebo effect (Hedges’ g = 0.298). Size of the placebo effect without choice was the only reliable moderator of this effect, whereby a greater effect of choice was associated with smaller placebo effects without choice. Conclusions Treatment choice can effectively facilitate the placebo effect, but this effect appears more pronounced in contexts where the placebo effect without choice is weaker. Because most evidence to date is experimental, translational studies are needed to test whether providing choice in clinical scenarios where placebo effects are weaker may help boost the placebo effect and thereby improve patient outcomes.

Associations Between Parents’ Health and Social Control Behaviors and Their Adolescent’s Self-Efficacy and Health Behaviors: Insights From the Family Life, Activity, Sun, Health, and Eating (FLASHE) survey

Background Parents can influence their children to live healthier lifestyles by modeling healthy behaviors and/or trying to persuade their children to engage in healthier activities. Adolescents and their parents tend to have similar eating and exercise patterns, but less is known about the simultaneous influence of parent’s health behavior and social control on adolescents’ self-efficacy and health behaviors, including whether their effect is moderated by parenting style. Purpose We examine the degree to which parents’ social control and health behaviors are associated with their adolescent’s self-efficacy and health behaviors, including whether parenting styles moderate these associations. Method We analyzed data from the Family Life, Activity, Sun, Health, and Eating project. Results We found that parents’ own health behaviors are positively and strongly associated with their adolescent’s health behaviors across four domains: fruit/vegetable consumption, junk food consumption, physical activity, and nonacademic screen time. We found positive, moderate-to-strong associations between parents’ use of social control and their adolescents’ fruit/vegetable and junk food consumption, small negative associations with screen time, and no associations with physical activity. The effects of social control for junk food consumption and screen time, however, depended on parents’ own behavior in those domains. Parent responsiveness moderated the relation between parents’ social control and their adolescent children’s self-efficacy and health behaviors. Conclusions The health behaviors parents model and their social control efforts are associated with their adolescents’ beliefs and behavior. Efforts to leverage parents as sources of influence must consider the context in which influence is enacted.

Psychological Predictors of Self-reported COVID-19 Outcomes: Results From a Prospective Cohort Study

Background Previous research has shown that psychological factors, such as stress and social support, are associated with greater susceptibility to viral respiratory illnesses and more severe symptoms. During the COVID-19 pandemic there has been a well-documented deterioration in psychological well-being and increased social isolation. This raises questions as to whether those experiencing psychological adversity during the pandemic are more at risk of contracting and/or experiencing COVID-19 symptoms. Purpose To examine the relationship between psychological factors and the risk of COVID-19 self-reported infection and the symptomatic experience of SARS-CoV-2 (indicated by the number and severity of symptoms). Methods As part of a longitudinal prospective observational cohort study, 1,087 adults completed validated measures of psychological well-being during April 2020 and self-reported incidence of COVID-19 infection and symptom experience across the pandemic through to December 2020. Regression models were used to explore these relationships controlling for demographic and occupational factors. Results Greater psychological distress during the early phase of the pandemic was significantly associated with subsequent self-reported SARS-CoV-2 infection as well as the experience of a greater number and more severe symptoms. Conclusions COVID-19 infection and symptoms may be more common among those experiencing elevated psychological distress. Further research to elucidate the mechanisms underlying these associations is needed.

Adherence to Recommended Preventive Behaviors During the COVID-19 Pandemic: The Role of Empathy and Perceived Health Threat

Background Coping via empathic responding may play a role in preventive behavior engagement during the COVID-19 pandemic, and unlike trait empathy, is a potentially alterable target for changing health behavior. Purpose Our goal was to examine the role of empathic responding in preventive behavior engagement during the COVID-19 pandemic, independent of trait empathy and perceived threat of COVID-19. Methods Participants (N = 2,841) completed a baseline survey early in the pandemic, and a follow-up survey approximately 2 weeks later (M = 13.50 days, SD = 5.61). Preventive health behaviors, including physical distancing and hygiene practices, were assessed at both timepoints. Hierarchical linear regression examined the contributions of trait empathy, perceived threat of COVID-19, and empathic responding at baseline to preventive behaviors at follow-up. Results Controlling for baseline levels of preventive behaviors and demographic covariates, trait empathy and threat of COVID-19 at baseline were each independently associated with preventive behaviors at follow-up. An interaction between perceived threat and empathic responding indicated that those perceiving high threat of COVID-19 at baseline tended to report engaging in preventive behaviors at follow-up regardless of their levels of empathic responding, whereas for those reporting low levels of perceived threat, higher levels of empathic responding were associated with higher engagement in preventive behavior. Conclusions When perceived threat of COVID-19 was low, higher empathic responding was associated with increased engagement in preventive behaviors regardless of trait empathy, suggesting that empathic responding can serve as an actionable target for intervention to promote preventive behavior during the pandemic.

Behavioral and Cognitive Outcomes of an Online Weight Loss Program for Men With Low Mood: A Randomized Controlled Trial

Background Depression and obesity are major health concerns and commonly co-exist, but men rarely seek help for these conditions. SHED-IT: Recharge was a gender-tailored eHealth program for men that generated clinically meaningful improvements in weight and depressive symptoms. Purpose To evaluate behavioral and psychological outcomes from the SHED-IT: Recharge intervention designed for overweight/obese men with low mood. Methods Overall, 125 men (18–70 years) with a BMI between 25 and 42 kg/m2 and depressive symptoms (PHQ-9 ≥ 5) were randomly allocated to SHED-IT: Recharge (n = 62) or wait-list control (n = 63) groups. The self-directed program targeted key health behaviors combined with online mental fitness modules based on cognitive behavioral therapy. Behavioral (e.g., physical activity) and psychological outcomes (e.g., cognitive flexibility) were assessed with validated measures at baseline, 3 months (post-test) and 6 months (follow-up). Intention-to-treat linear mixed models examined treatment effects, which were adjusted for covariates, and effect size estimated (Cohen’s d). Results At post-test, intervention men achieved small-to-medium improvements in several health behavior outcomes including moderate-to-vigorous physical activity, light physical activity, sedentary behavior, sleep, energy intake, portion size, and risky alcohol consumption (range, d = 0.3–0.5), when compared with the control group. Intervention effects were also observed for perceived physical self-worth, perceived physical strength, cognitive flexibility, and behavioral activation (range, d = 0.3–0.8). No effects were found for fruit and vegetable intake, or mindful attention. Most effects were maintained at follow-up. Conclusions This gender-tailored, eHealth program with integrated mental fitness support elicited meaningful improvements in health behaviors and psychological outcomes for men with low mood.

A Randomized Clinical Trial Demonstrating Feasibility and Preliminary Efficacy of a Videoconference-Delivered Physical Activity Lifestyle Intervention Among Adolescents With a Congenital Heart Defect

Background Individuals with congenital heart defects are at increased risk for developing further cardiovascular complications, which can be mitigated by increasing physical activity. Given that positive health behaviors begin declining during older adolescence, it is vital to promote lifestyle changes in this population. Purpose The current study aims to (a) determine the feasibility/acceptability of the Congenital Heart Disease Physical Activity Lifestyle (CHD-PAL) intervention among adolescents (ages 15–18) with moderate and complex congenital heart defects, and (b) estimate the preliminary efficacy of CHD-PAL for increasing time spent in moderate-to-vigorous physical activity (MVPA) and cardiorespiratory fitness and decreasing sedentary behavior. Methods Eligible participants were randomized into either CHD-PAL (eight 30-min videoconferencing sessions over 20 weeks with an interventionist + Fitbit + exercise prescription) or a comparator (Fitbit + exercise prescription). Results Sixty adolescents were randomized (76% recruitment rate; 94% of participants were retained from baseline to follow-up). Most adolescents (73%) and their parents/guardians (76%) reported that the trial was enjoyable. While there was no effect of arm on change in MVPA, sedentary behavior, or cardiorespiratory fitness for the entire sample, among those who engaged in <21 min of MVPA on average at baseline, adolescents in the CHD-PAL intervention had an increase of 16 min/day of MVPA more than comparators (d = 0.90). Conclusions The CHD-PAL intervention warrants examination in a larger trial to establish efficacy among those adolescents with a congenital heart defect who engage in <21 min of MVPA/day and should include follow-up assessments to examine effect durability. Clinical trials registration NCT03335475.

The Relationship Between Racial Prejudice and Cardiovascular Disease Mortality Risk at the State and County Level

Background Robust evidence shows that perceived discrimination among stigmatized groups is associated with negative health outcomes. However, little work has examined whether holding prejudiced attitudes toward others is associated with health risks for prejudiced individuals. Purpose The study is a test of the hypothesis that holding prejudicial attitudes has negative health implications for both the holders and targets of prejudicial attitudes. Methods The project connected data (2003–2015) at the state and county levels on average explicit and implicit prejudice held by White, Black, and Native American respondents from Project Implicit with data on cardiovascular disease (CVD) mortality for White, Black, and Native American individuals from the CDC Wonder database. Separate analyses regressed implicit and explicit prejudice on CVD mortality risk for White, Black, and Native American individuals, respectively. Results At the state level, among White individuals, explicit prejudice toward Blacks (β = .431, p =.037) and implicit prejudice toward Native Americans (β = .283, p = .045) were positively associated with greater CVD mortality for Whites. At the county level, White individuals’ implicit prejudice toward Blacks (β =.081, p = .015) and Black individuals’ implicit prejudice toward Whites (β = −.066, p = .018) were associated with greater CVD mortality for Whites. Also, at the county-level, among Black individuals, higher implicit (β = −.133, p < .001) and explicit (β = −.176, p < .001) prejudice toward Whites predicted CVD mortality for Blacks. Moreover, explicit prejudice held by White individuals was positively associated with Blacks’ county-level CVD deaths (β = .074, p = .036). Conclusions This evidence suggests that across racial groups, holding racial prejudice is associated with CVD mortality risk for both the prejudiced and the stigmatized groups. Future research should verify the reliability of this potential public health effect with additional work explicating moderators and mediators to inform surveillance and interventions.

Testing the Associations Between State and Trait Anxiety, Anger, Sadness, and Ambulatory Blood Pressure and Whether Race Impacts These Relationships

Background Anxiety, anger, and sadness are related to elevated ambulatory blood pressure (ABP), yet it is unclear whether each emotion exerts unique effects. Moreover, an understanding of who might be most susceptible to the negative effects of these emotions is limited, with the trait tendency to experience them or one’s race as potential moderators. Purpose The study examined the potential for differential effects of momentary anxiety, anger, and sadness on ABP. The study assessed whether a trait tendency to experience these negative emotions and/or race (Black vs. non-Black) would moderate these relationships. Methods Participants (n = 153) completed trait anxiety, anger, and depressive symptoms measures at baseline. ABP was collected over two 24-hour periods 3–4 months apart. Momentary measures of anxiety, anger, and sadness were assessed via ecological momentary assessment (EMA) after each ABP reading. Results Momentary anxiety consistently predicted diastolic blood pressure but not systolic blood pressure. Momentary anger and sadness did not predict blood pressure (BP). Conditional effects were found with momentary anxiety and anger predicting elevated BP in those individuals with trait anxiety/anger at its mean. Trait anxiety and depression consistently predicted heightened BP in Black participants. Trait anger did not moderate the relationships between negative emotions and ABP. Conclusions Findings suggest that momentary anxiety and anger should be given attention as potential risk factors for hypertension and highlight the unique perspective of EMA methods. Black participants who were more anxious and depressed experienced heightened BP, with anxiety and depression providing possible intervention targets in improving racial disparities in cardiovascular health.

The Interplay Between Strictness of Policies and Individuals’ Self-Regulatory Efforts: Associations with Handwashing During the COVID-19 Pandemic

Background Patterns of protective health behaviors, such as handwashing and sanitizing during the COVID-19 pandemic, may be predicted by macro-level variables, such as regulations specified by public health policies. Health behavior patterns may also be predicted by micro-level variables, such as self-regulatory cognitions specified by health behavior models, including the Health Action Process Approach (HAPA). Purpose This study explored whether strictness of containment and health policies was related to handwashing adherence and whether such associations were mediated by HAPA-specified self-regulatory cognitions. Methods The study (NCT04367337) was conducted among 1,256 adults from Australia, Canada, China, France, Gambia, Germany, Israel, Italy, Malaysia, Poland, Portugal, Romania, Singapore, and Switzerland. Self-report data on cross-situational handwashing adherence were collected using an online survey at two time points, 4 weeks apart. Values of the index of strictness of containment and health policies, obtained from the Oxford COVID-19 Government Response Tracker database, were retrieved twice for each country (1 week prior to individual data collection). Results Across countries and time, levels of handwashing adherence and strictness of policies were high. Path analysis indicated that stricter containment and health policies were indirectly related to lower handwashing adherence via lower self-efficacy and self-monitoring. Less strict policies were indirectly related to higher handwashing adherence via higher self-efficacy and self-monitoring. Conclusions When policies are less strict, exposure to the SARS-CoV-2 virus might be higher, triggering more self-regulation and, consequently, more handwashing adherence. Very strict policies may need to be accompanied by enhanced information dissemination or psychosocial interventions to ensure appropriate levels of self-regulation.
