Fear of side effects is the main motive for vaccine refusal. However, before COVID-19 pandemic, little attention had been paid to actual experience adverse events and its relationship with hesitancy. This scoping review aimed analyze impact VH on EAE vice versa. We reviewed 55 articles. Most studies focused vaccination employed cross-sectional surveys self-reported indicators. These identified significant correlations between VH. Social cognitive models shed some light influence VH, while converse usually explained by nocebo effect that predominately accounts converse. emerging research field hampered inconsistencies in theoretical explanations, assessments relationship, measurements these two phenomena. A more comprehensive consideration individual experience, both objective subjective, would help develop effective communication strategies improve pharmacological surveillance.

Abstract Generic medications are developed to match brand-name in terms of active ingredients, quality, safety, and strength. Because generic cost less than their counterparts, they present an opportunity reduce financial burden for patients social institutions. Studies show, however, that often possess negative beliefs evaluations medications, thereby undermining use effectiveness. In two pre-registered online experiments with community adults (Total N = 750), we tested the effect attribute framing on attitudes, attitude certainty, effectiveness regarding medications. both experiments, (positive vs. negative) brand status (generic name) allergy medication were manipulated a 2 × between-participant design. The results produced strong effects manipulations. Specifically, medicines rated more favorably positive frame as compared frame. Also, branded positively medicines. contrast hypotheses, variables did not reliably interact predict outcomes. These held constant across multiple sets stimuli dependent measures. findings support position can be employed improve over-the-counter

This systematic review analyzed the effectiveness of key persuasive strategies – source, appeal, framing, and evidence (SAFE) on COVID-19 vaccination intention. Quantitative studies were searched in Web Science, Scopus, PubMed following PRISMA guidelines. From 61 that met inclusion criteria, source framing are most commonly applied SAFE strategies. However, characteristics a more consistent influence vaccine intentions than message strategies, with expert sources general practitioners emerging as contributing to greater intentions. In addition, range mediators moderators process through which impact Framing effects, particular, moderated by political identity, characteristics, perceptions. Tests mediating processes highlight how health behavior judgments (e.g. perceived benefits, risks, trust vaccination, severity) response/perceptions counterarguing, similarity/empathy) operate intervening factors between Overall, when apply various structural approaches (narrative elements, fear appeals, cues) promotion campaigns, they should be cognizant who is providing appeal. Targeted populations may benefit from different elements if integrated resonate audience.

Augmented patient-practitioner interactions that enhance therapeutic alliance can increase the placebo effect to sham treatment. Little is known, however, about of these on maladaptive health outcomes (i.e., nocebo effect). Healthy participants (N = 84) were randomised a 3-day course Oxytocin nasal drops (actually, treatment) in conjunction with high-warmth interaction (Oxy-HW: N 28), low-warmth (Oxy-LW: 28) or no treatment control group (NT: 28). All informed could psychological well-being but was associated several potential side effects. Treatment-related effects, unwarned symptoms, and measured at baseline all post-treatment days. Side reporting increased Oxy-LW condition compared other groups across Conversely, observed Oxy-HW condition, relative conditions, only Day 1. Among those receiving treatment, positive negative expectations, treatment-related worry, did not vary by interaction-style, while inversely level individual. Results have important implications for practice, suggesting poorer quality may reduce beneficial also exacerbate are maladaptive.

As a major concern shared by parents globally, COVID-19 vaccine safety is typically being messaged to the public in negative frame many countries. However, whether framing have an effect on when vaccinating their children unclear. Here we implement online survey with convenience sample of 3,861 living mainland China, all over 18 years old and at least one child under 18. The were randomly assigned receive information about either (incidence side effects) or positive (the inverse incidence effects), compare parental reactions range questions communication, risk perception, trust, involvement behavioral intention. We found that more likely regard as relevant policy support higher priority for government receiving positively framed (p = 0.002). For some specific subgroups, group showed lower perception trust (p<0.05). This suggests messages show effective performance than terms involvement, well which may lead reflection adjust current widespread use framing. Our findings inform how governments health care workers strategically choose design information, important implications promoting vaccination future.

How health workers frame their communication about vaccines' probability of adverse side effects could play an important role in people's intentions to be vaccinated (e.g., positive frame: are unlikely v. negative there is a chance effects). Based on the pragmatic account framing as implicit advice, we expected that participants would report greater vaccination when trustworthy physician framed risks positively (v. negatively), but this effect reduced or reversed was untrustworthy.In 4 online experiments (n = 191, snowball sampling and n 453, 451, 464 UK residents via Prolific; Mage≈ 34 y, 70% women, 84% White British), manipulated trustworthiness how they risk scenario (i.e., Participants reported intention, level distrust care systems, COVID-19 conspiracy beliefs.Physicians who were untrustworthy) consistently led increase way described mattered too.

As the global pandemic perpetuates, keeping population vaccinated will be imperative to maintain societal protection from SARS-CoV-2 (COVID-19) virus. However, while empirical evidence regarding predictors of intention receive a first COVID-19 vaccine has amassed, our understanding psychological and behavioral drivers continued vaccination remains limited. In this pre-registered study (UK: AsPredicted#78370|Australia: AsPredicted#81667), factors predicting booster were investigated in two adult samples UK (N = 1222) Australia 1197) that nationally representative on age, gender, geographic location. High levels intent found (73% 67%, respectively). Exploratory Structural Equation Modelling (ESEM) revealed three key emerged across both Australian samples: concern virus, positive perceptions vaccines, perceived severity side effects experienced last dose. Several additional (age, months since vaccine, familiarity with effects, regularly receiving influenza vaccine) present dataset. These findings provide important targeting virus may serve participation programme, paving way for future behavioural research area.

Abstract The perception of taking a generic, relative to brand, medication has been demonstrated exacerbate the nocebo effect. Conversely, positive attribute framing shown attenuate However, little is known about longevity nor how it interacts with generic versus brand treatment cues. Healthy participants ( N = 205) were randomised receive either sham‐modafinil capsules or appearance, in conjunction standard negative side effect (brand‐negative: 42; generic‐negative: 41) (brand‐positive: 40; generic‐positive: 40). remainder no‐treatment control 42). Participants informed that modafinil could enhance alertness and cognitive performance reduce fatigue. Critically, was described as having several potential effects. Treatment‐related effects, alertness, fatigue measured at baseline, 30‐min post‐treatment 24 h later. Nocebo placebo effects observed across modafinil‐treated control. Positive significantly reduced warned for h. Perceived likelihood, severity, worry mediated nocebo, but not framing, Results have important implications presentation information, providing route unwanted medication.
