Article Synopsis
  • The study aims to analyze how smoking and vaping behaviors in different groups (smokers, vapers, and nonsmokers) change in response to tobacco control policies, like price hikes and health info.
  • Conducted with 525 adults aged 18 to 88, the research found that most vapers also smoke, and nonsmokers show concern over health risks and costs related to vaping.
  • Results indicate that while increasing cigarette prices might somewhat push smokers to vape, it's the awareness of health dangers that significantly influences nonsmokers against vaping, with little effect on their response to price increases or nicotine changes.

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.

Background: A variety of intervention strategies to improve Human Papillomavirus (HPV) vaccination rates in adults exist; however, they have shown varying efficacy and inconsistent outcomes.

Purpose: This meta-analysis tested the efficacy of HPV vaccination interventions for adults in increasing vaccine intentions, rates of initiation of the vaccine series, and completion rates. The study also tested potential moderators (intervention strategy, theory-based versus nontheory-based interventions, race/ethnicity, gender, study quality) of relationships between intervention receipt and vaccine intentions.

Rationale: Mitigating the spread of COVID-19 requires that people understand the need for and engage in protective behaviors. Given the complexity and rapid progression of media information about the pandemic, health literacy could be essential to acquiring the accurate beliefs, concern for societal risks, and appreciation of restrictive policies needed to motivate these behaviors. Yet with the increasingly politicized nature of COVID-related issues in the United States, health literacy could be an asset for those with more liberal views but less so for those with more conservative views.

Article Synopsis
  • Rates of Type 1 diabetes are increasing, and managing the condition can become more challenging during adolescence, especially in terms of communication between teens and their parents.
  • The study focused on how parents' emotional responses (like anger or positivity) to their adolescents' disclosures about diabetes management impact when and how often teens decide to share information with them in the future.
  • Results showed that teens were less likely to disclose information soon after parents reacted with anger or intense positive emotions, highlighting the importance of supportive parental responses for effective chronic illness management.

Objectives: Based on the common-sense model of self-regulation, this study aimed to explicate the mechanism underlying the effect of illness representations on self-care behaviours and anxiety symptoms among patients with type 2 diabetes.

Methods: A telephone survey was administered to 473 patients in Hong Kong. Structural equation modelling was used to test if threat and control perceptions regarding diabetes would be associated with self-reported self-care behaviours and anxiety symptoms through adoption of adaptive/maladaptive coping strategies and diabetes-related self-efficacy.

Evidence supports the use of graphic warnings to educate the public about the health harms of smoking and suggests warnings eliciting negative emotional responses may be more effective. This study aimed to replicate a preliminary theory-based model whereby perceived new knowledge promotes discouragement from smoking through its impact on worry about smoking with a different sample and using a new set of cigarette graphic warnings. We explored if the pattern extended to encouragement to use e-cigarettes, and if age and user group moderated the indirect effects of these models.

Climate change poses a multifaceted, complex, and existential threat to human health and well-being, but efforts to communicate these threats to the public lag behind what we know how to do in communication research. Effective communication about climate change's health risks can improve a wide variety of individual and population health-related outcomes by: (1) helping people better make the connection between climate change and health risks and (2) empowering them to act on that newfound knowledge and understanding. The aim of this manuscript is to highlight communication methods that have received empirical support for improving knowledge uptake and/or driving higher-quality decision making and healthier behaviors and to recommend how to apply them at the intersection of climate change and health.

Marijuana use among pregnant and breastfeeding women is on the rise and carries risks for infant health and well-being. Decisions to use marijuana while pregnant and breastfeeding are motivated by beliefs that use poses minimal risk to infants and offers benefits to maternal users. Misperceptions and usage trend higher among disadvantaged populations.

Objectives: (1) Test whether a mental imagery-based self-regulation intervention increases physical activity behaviour over 90 days; (2) Examine cognitive and affective precursors of change in physical activity behaviour.

Design: A randomized control trial with participants (N = 500) randomized to one of six intervention conditions in a 3 (risk communication format: bulleted list, table, risk ladder) x 2 (mental imagery behaviour: physical activity, active control [sleep hygiene]) factorial design.

Methods: After receiving personalized risk estimates via a website on a smartphone, participants listened to an audiorecording that guided them through a mental imagery activity related to improving physical activity (intervention group) or sleep hygiene behaviour (active control).

The desire to engage in waterpipe tobacco smoking (WTS) may occur when smokers and nonsmokers conjure positive mental simulations of WTS. However, effects of these simulations on desire to smoke waterpipe tobacco and potential mediators are unexplored. This research addressed these effects among young adult waterpipe tobacco smokers and nonsmokers.

Objective: Suboptimal self-care by individuals with diabetes mellitus (DM) is a significant public health concern. The common-sense model (CSM) proposes that illness representations are associated with coping and health outcomes across various conditions. The present study examined the efficacy of a CSM-based intervention in improving illness representations, self-care, self-care self-efficacy, use of adaptive coping strategies, and glycated hemoglobin among individuals with type 2 DM (T2DM).

Background: Personalized medicine may increase the amount of probabilistic information patients encounter. Little guidance exists about communicating risk for multiple diseases simultaneously or about communicating how changes in risk factors affect risk (hereafter "risk reduction").

Purpose: To determine how to communicate personalized risk and risk reduction information for up to 5 diseases associated with insufficient physical activity in a way laypeople can understand and that increases intentions.

Emergency responders (police, fire, ambulance and defence force personnel) risk exposure to dangerous and traumatic events, and the possible subsequent development of post-traumatic stress disorder. Consequently, partners of these emergency responders risk developing secondary traumatic stress (STS) from vicarious exposure to the trauma through communication and engagement with their responders. A mixed-methods study of the partners of emergency responders in New Zealand examined the extent of such partner-associated STS.

Unlabelled: 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.

Greater habitual emotional suppression (ES)-assessed by the suppression subscale of the emotion regulation questionnaire (ERQ-ES; Gross & John, 2003) and the Courtauld emotion control scale (CECS; Watson & Greer, 1983)-is associated with a range of negative outcomes, which are assumed to arise because habitual ES measures capture the tendency to use ES in response to emotions. The current studies directly test whether habitual ES measures actually capture the response-focused use of ES when emotions arise within social interactions. We conduct these validation tests by integrating measures of habitual ES with naturalistic assessments of negative emotions and the situational use of ES during emotionally relevant interactions with romantic partners (Study 1, = 200; Study 3, = 170) and social interactions with close others in daily life (Study 2, = 430).

An expanded Common-Sense Model (CSM) contextualised to the self-regulation of cancer recurrence risk identifies risk representational attributes and recurrence worry as primary processes motivating protective behaviours in cancer survivors. A systematic review examined evidence for CSM hypotheses regarding how these processes influence diet and physical activity (PA) among survivors. A research agenda is outlined and used to evaluate the evidence base.

Conceptual frameworks are useful in research because they can highlight priority research domains, inform decisions about interventions, identify outcomes and factors to measure, and display how factors might relate to each other to generate and test hypotheses. Discovery, translational, and implementation research are all critical to the overall mission of genomic medicine and prevention, but they have yet to be organized into a unified conceptual framework. To fill this gap, our diverse team collaborated to develop the Genomic Medicine Integrative Research (GMIR) Framework, a simple but comprehensive tool to aid the genomics community in developing research questions, strategies, and measures and in integrating genomic medicine and prevention into clinical practice.
