Neurophysiological Profile of Antismoking Campaigns

Over the past few decades, antismoking public service announcements (PSAs) have been used by governments to promote healthy behaviours in citizens, for instance, against drinking before the drive and against smoke. Effectiveness of such PSAs has been suggested especially for young persons. By now, PSAs efficacy is still mainly assessed through traditional methods (questionnaires and metrics) and could be performed only after the PSAs broadcasting, leading to waste of economic resources and time in the case of Ineffective PSAs. One possible countermeasure to such ineffective use of PSAs could be promoted by the evaluation of the cerebral reaction to the PSA of particular segments of population (e.g., old, young, and heavy smokers). In addition, it is crucial to gather such cerebral activity in front of PSAs that have been assessed to be effective against smoke (Effective PSAs), comparing results to the cerebral reactions to PSAs that have been certified to be not effective (Ineffective PSAs). &e eventual differences between the cerebral responses toward the two PSA groups will provide crucial information about the possible outcome of new PSAs before to its broadcasting. &is study focused on adult population, by investigating the cerebral reaction to the vision of different PSA images, which have already been shown to be Effective and Ineffective for the promotion of an antismoking behaviour. Results showed how variables as gender and smoking habits can influence the perception of PSA images, and how different communication styles of the antismoking campaigns could facilitate the comprehension of PSA’s message and then enhance the related impac

Implementing cardiovascular disease prevention guidelines to translate evidence-based medicine and shared decision making into general practice: theory-based intervention development, qualitative piloting and quantitative feasibility

Background: The use of cardiovascular disease (CVD) prevention guidelines based on absolute risk assessment is poor around the world, including Australia. Behavioural barriers amongst GPs and patients include capability (e.g. difficulty communicating/understanding risk) and motivation (e.g. attitudes towards guidelines/medication). This paper outlines the theory-based development of a website for GP guidelines, and piloting of a new risk calculator/decision aid. Methods: Stage 1 involved identifying evidence-based solutions using the Behaviour Change Wheel (BCW) framework, informed by previous research involving 400 GPs and 600 patients/consumers. Stage 2 co-developed website content with GPs. Stage 3 piloted a prototype website at a national GP conference. Stage 4 iteratively improved the website based on "think aloud" interviews with GPs and patients. Stage 5 was a feasibility study to evaluate potential efficacy (guidelines-based recommendations for each risk category), acceptability (intended use) and demand (actual use over 1 month) amongst GPs (n = 98). Results: Stage 1 identified GPs as the target for behaviour change; the need for a new risk calculator/decision aid linked to existing audit and feedback training; and online guidelines as a delivery format. Stage 2-4 iteratively improved content and format based on qualitative feedback from GP and patient user testing over three rounds of website development. Stage 5 suggested potential efficacy with improved identification of hypothetical high risk patients (from 26 to 76%) and recommended medication (from 57 to 86%) after viewing the website (n = 42), but prescribing to low risk patients remained similar (from 19 to 22%; n = 37). Most GPs (89%) indicated they would use the website in the next month, and 72% reported using it again after one month (n = 98). Open feedback identified implementation barriers including a need for integration with medical software, low health literacy resources and pre-consultation assessment. Conclusions: Following a theory-based development process and user co-design, the resulting intervention was acceptable to GPs with high intentions for use, improved identification of patient risk categories and more guidelines-based prescribing intentions for high risk but not low risk patients. The effectiveness of linking the intervention to clinical practice more closely to address implementation barriers will be evaluated in future research

A Critical Examination of the FDA’s Efforts to Preempt Failure-to-Warn Claims

This article explores the legality and wisdom of the FDA’s effort to persuade courts to find most failure-to-warn claims preempted. The article first analyzes the FDA’s justifications for reversing its long-held views to the contrary and explains why the FDA’s position cannot be reconciled with its governing statute. The article then examines why the FDA’s position, if ultimately adopted by the courts, would undermine the incentives drug manufacturers have to change labeling to respond to newly-discovered risks. The background possibility of failure-to-warn litigation provides important incentives for drug companies to ensure that drug labels reflect accurate and up-to-date safety information. The article next explains why the agency’s view that it is capable of singlehandedly regulating the safety of drugs is unrealistic. The agency does not have the resources to perform the Herculean task of monitoring the performance of every drug on the market. Both the Institute of Medicine and the Government Accountability Office have explained the shortcomings in the FDA’s recent performance, and they express doubt that the FDA is in capable of facing an increasingly challenging future. The article then explains how state damages litigation helps uncover and assess risks that are not apparent to the agency during a drug’s approval process, and why this “feedback loop” enables the agency to better do its job. FDA approval of drugs is based on clinical trials that involve, at most, a few thousand patients and last a year or so. These trials cannot detect risks that are relatively rare, affect vulnerable sub-populations, or have long latency periods. For this reason, most serious adverse effects do not become evident until a drug is used in larger population groups for periods in excess of one year. Time and again, failure-to-warn litigation has brought to light information that would not otherwise be available to the FDA, to doctors, to other health care providers, and to consumers. And failure-to-warn litigation often has preceded and clearly influenced FDA decisions to modify labeling, and, at times, to withdraw drugs from the market

Psychological Pathways Linking Public Trust During the Coronavirus Pandemic to Mental and Physical Well-being

The well-being of the public during the 2019 coronavirus (COVID-19) pandemic is deeply rooted in institutional trust in the government’s risk communication effort. The objective of this study was to examine the psychological pathway through which public trust in the government is associated with mental and physical well-being. We collected cross-sectional data from 501 participants aged ≥18 years using an online panel. Public trust in the government was assessed as our exposure variable. We screened for psychological distress by combining the Patient Health Questionnaire and the General Anxiety Disorder scale. Physical well-being was examined using self-rated health. We further assessed the roles of risk perceptions. The author conducted a one-way analysis of variance (ANOVA), Pearson’s correlations, multivariable regressions, and mediation analyses (using the Preachers and Hayes’ approach). Participants were 55.29% female, 67.86% Caucasian/white with a mean age of 32.44 ± 11.94 years. Public trust in the government regarding COVID-19 was negatively correlated with psychological distress (r = −0.20; p \u3c 0.001) and positively associated with physical well-being (r = 0.13; p \u3c 0.001). After adjusting for sociodemographic and socioeconomic factors, public trust remained negatively associated with psychological distress (β = −0.19; 95% confidence intervals, [CI] −0.30, −0.09) and positively associated with physical well-being (β = 0.26; 95% CI [0.16, −0.37]). Perceived self-efficacy to practice COVID-19 protective behavior partially mediated the relationship between public trust and psychological distress (13.07%); and physical well-being (28.02%). Perceived self-efficacy to protect self against COVID-19 infection can serve as a psychological pathway through which public trust may be associated with mental and physical health.

Tackling food marketing to children in a digital world: trans-disciplinary perspectives. Children’s rights, evidence of impact, methodological challenges, regulatory options and policy implications for the WHO European Region

There is unequivocal evidence that childhood obesity is influenced by marketing of foods and non-alcoholic beverages high in saturated fat, salt and/or free sugars (HFSS), and a core recommendation of the WHO Commission on Ending Childhood Obesity is to reduce children’s exposure to all such marketing. As a result, WHO has called on Member States to introduce restrictions on marketing of HFSS foods to children, covering all media, including digital, and to close any regulatory loopholes. This publication provides up-to-date information on the marketing of foods and non-alcoholic beverages to children and the changes that have occurred in recent years, focusing in particular on the major shift to digital marketing. It examines trends in media use among children, marketing methods in the new digital media landscape and children’s engagement with such marketing. It also considers the impact on children and their ability to counter marketing as well as the implications for children’s rights and digital privacy. Finally the report discusses the policy implications and some of the recent policy action by WHO European Member States

Familiarity, challenge and processing of persuasion messages

Tese apresentada para cumprimento dos requisitos necessários à obtenção do grau de Doutor em Psicologia na área de especialização de Psicologia Social realizada sob a orientação de Teresa Garcia-Marques e co-orientação de James BlascovichThis thesis investigates the relationship between an experience of familiarity and a motivational state of challenge with how information is processed in a persuasion context. Previous research on social cognition has suggested that familiarity not only impacts a wide range of cognitive processes, but also regulates the activation of a more analytic information-processing mode, an assumption of the Familiarity of As a Regulation Mechanism model (Garcia-Marques, 1999; Garcia-Marques et al., 2010). On a different field, research on the Biopsychosocial model of challenge and threat (Blascovich et al., 1993, 1999) has suggested that familiarity influences the activation of a motivational state of challenge. These two approaches suggest, therefore, that an experience of familiarity is able to influence both cognitive and motivational processes features. The overlap between the assumptions underlying both approaches is here explored being suggested the possibility that they might be closely related. For example, both approaches assume that an experience of familiarity signals individuals with necessary resources available and accessible in memory to deal with the situation. In this thesis, we have explored the relationship between these two approaches developing four experiments that could simultaneously inform about information-processing modes and assess the cardiovascular responses that typically map the motivational state. Experiment 1 showed the expected association of familiarity with non-analytical processing and at the same time the exhibition of a challenge type of cardiovascular responses. Interestingly these two effects that were activated by the same source, familiarity, did not seem to be related. Neither the observed cardiovascular indexes explained why individuals engaged in less analytic processing, nor did this processing mode was associated with the cardiovascular indexes. To continue exploring the relationship between these two effects, experiment 2 tested if the motivational state of challenge could promote less analytic processing by itself. Although the manipulation of motivational challenge did in fact influence how information was processed and was associated with the correspondent cardiovascular pattern of challenge, once again, the cardiovascular indexes were not related with the cognitive effect. The subsequent studies were designed to directly test the observed independence of both processes. We hypothesized that this observed dissociation could be in some way related with the fact that both processes depend on different levels of task-engagement. Experiment 3 replicates experiment 2 by manipulating the motivational state of challenge and adding to it a manipulation of task-engagement (presence versus absence of an observer). Results revealed that the two previously observed effects were only found in the task-engagement condition (i.e. in the presence of the observer). In experiment 4, we went back to the original study of the experience of familiarity and thus replicated experiment 1, adding to it the same manipulation of task-engagement. Results revealed that although the motivational effects disappeared in the low engagement condition (i.e. those who were alone), the cognitive impact was always observed regardless of the task-engagement level. To our view, these results are suggesting that the two effects here approached – the cognitive and motivational impact of familiarity, are related indeed. However, they are related under specific conditions, for example, the degree with which individuals are engaged with the task. As such, we claim that their co-occurrence does not mean that they are part of the same process. This assumption is discussed and a set of new experiments is proposed to further support it.Fundação para a Ciência e Tecnologi

A theoretical and practical approach to a persuasive agent model for change behaviour in oral care and hygiene

There is an increased use of the persuasive agent in behaviour change interventions due to the agent‘s features of sociable, reactive, autonomy, and proactive. However, many interventions have been unsuccessful, particularly in the domain of oral care. The psychological reactance has been identified as one of the major reasons for these unsuccessful behaviour change interventions. This study proposes a formal persuasive agent model that leads to psychological reactance reduction in order to achieve an improved behaviour change intervention in oral care and hygiene. Agent-based simulation methodology is adopted for the development of the proposed model. Evaluation of the model was conducted in two phases that include verification and validation. The verification process involves simulation trace and stability analysis. On the other hand, the validation was carried out using user-centred approach by developing an agent-based application based on belief-desire-intention architecture. This study contributes an agent model which is made up of interrelated cognitive and behavioural factors. Furthermore, the simulation traces provide some insights on the interactions among the identified factors in order to comprehend their roles in behaviour change intervention. The simulation result showed that as time increases, the psychological reactance decreases towards zero. Similarly, the model validation result showed that the percentage of respondents‘ who experienced psychological reactance towards behaviour change in oral care and hygiene was reduced from 100 percent to 3 percent. The contribution made in this thesis would enable agent application and behaviour change intervention designers to make scientific reasoning and predictions. Likewise, it provides a guideline for software designers on the development of agent-based applications that may not have psychological reactance

The Fear Management Model: Building an Integrative Fear Appeal Theory through System Dynamics

[[abstract]]This paper attempts to refine the Extended Parallel Process Model by adding the notion of hope to highlight the significant role of fear in fear appeals. Using System Dynamics modeling methods to reformulate the key constructs and integrate the ideas drawn from theories of multiple disciplines, the relationship between danger control and fear control processes are modified. Accordingly, the Fear Management Model is devised to fix the flaws and resolve the major unanswered questions in fear appeal literatures. Moreover, the implications for helping resistant audiences to pursue adaptive behaviors are discussed. Fourteen propositions are proposed for guiding hypothesis development in future research.[[notice]]補正完
