RESUMEN

The effectiveness of strategic psychology-based marketing techniques for increasing public support for conservation is poorly understood. We assessed how such techniques affect support for tropical rainforest restoration with a controlled online experiment with 1166 nationally representative residents of the United Kingdom. We tested whether support increased when adding ecosystem service (ES) framings to typical nongovernmental organizations' (NGOs) biodiversity-focused messages that emphasize benefits to UK residents or people living near the tropical restoration site and a dynamic social norm nudge that emphasized increasing popularity of environmental restoration. We considered how respondents' psychological traits (nature connection, self-efficacy, psychological benefits of supporting charities, awareness of environmental degradation in the Global South, and climate change skepticism) influenced responses. Outcomes included respondents' reported advertisement sufficiency, sympathetic attitudes, behavioral support, and financial support. The study population typically found advertisements sufficient and exhibited sympathetic attitudes and financial, but not behavioral, support. Younger people exhibited greater conservation support than older respondents. Messages framed solely on biodiversity conservation were as effective as those highlighting additional ES benefits received by UK residents and people near the tropical restoration site. This suggests that framing around ESs, rather than nature's intrinsic value, may not strengthen public support for conservation. The dynamic social norm nudge had perverse effects. It reduced perceived social norms and most outcome variables. Alternative dynamic norm nudges warrant testing, but our results support research suggesting dynamic norm nudges can be ineffective when associated with activism, challenging their use by conservation NGOs. Psychological benefits of supporting charities and perceived self-efficacy increased support for advertisements, highlighting the benefits of including impact statements relating respondents' support to specific outcomes. Climate change skepticism decreased support, whereas nature connection and perceived static social norms increased it, highlighting the need to increase nature connection and pro-environmental social norms to elevate public support for conservation.

Impactos del encuadre de los mensajes sobre servicios ambientales y las normas sociales dinámicas sobre el apoyo público hacia la restauración de bosques tropicales Resumen Sabemos poco sobre la eficiencia de las técnicas de mercadotecnia basadas en la psicología estratégica para aumentar el apoyo público a la conservación. Evaluamos cómo afectan dichas técnicas al apoyo a la restauración de la selva tropical mediante un experimento controlado en línea con 1,166 residentes del Reino Unido representativos a nivel nacional. Comprobamos si el apoyo aumentaba al añadir marcos de servicios ambientales a los mensajes típicos de las organizaciones no gubernamentales (ONG) centrados en la biodiversidad, que hacen hincapié en los beneficios para los residentes del Reino Unido o las personas que viven cerca del lugar de restauración tropical y un empuje dinámico de normas sociales que hacía hincapié en la creciente popularidad de la restauración ecológica. Analizamos la influencia de los rasgos psicológicos de los encuestados (conexión con la naturaleza, autoeficacia, beneficios psicológicos de apoyar a organizaciones benéficas, experiencia de degradación ambiental en el Sur Global y escepticismo ante el cambio climático) sobre las respuestas. Los resultados fueron la suficiencia de los anuncios, las actitudes de simpatía, el apoyo conductual y el apoyo económico. En general, la población del estudio consideró que los anuncios eran suficientes y mostró actitudes de simpatía y apoyo económico, pero no conductuales. La población más joven mostró un mayor apoyo a la conservación que los encuestados de más edad. Los mensajes centrados únicamente en la conservación de la biodiversidad fueron tan eficaces como los que destacaban los beneficios adicionales de los servicios ambientales recibidos por los residentes del Reino Unido y las personas cercanas al lugar de restauración tropical. Esto sugiere que el encuadre en torno a los servicios ambientales, en lugar del valor intrínseco de la naturaleza, puede no reforzar el apoyo público a la conservación. El empuje dinámico de la norma social tuvo efectos perversos ya que redujo las normas sociales percibidas y la mayoría de las variables de resultado. Es necesario probar otros incentivos dinámicos, pero nuestros resultados corroboran las investigaciones que sugieren que los incentivos dinámicos pueden ser ineficaces cuando se asocian con el activismo, lo que cuestiona su uso por parte de las ONG de la conservación. Los beneficios psicológicos por apoyar a organizaciones benéficas y la autoeficacia percibida aumentaron el apoyo a los anuncios, lo que resalta las ventajas de incluir declaraciones de impacto que relacionen el apoyo de los encuestados con resultados específicos. El escepticismo ante el cambio climático redujo el apoyo, mientras que la conexión con la naturaleza y las normas sociales estáticas percibidas lo aumentaron, lo que destaca la necesidad de aumentar la conexión con la naturaleza y las normas sociales proambientales para elevar el apoyo público a la conservación.

RESUMEN

Behavioral nudges in Facebook ads reached nearly 15 million people across six diverse countries and, consequently, many thousands took the step of navigating to governments' vaccine signup sites. However, none of the treatment ads caused significantly more vaccine signup intent than placebo uniformly across all countries. Critically, reporting the descriptive norm that 87% of people worldwide had either been vaccinated or planned vaccination-social proof-did not meaningfully increase vaccine signup intent in any country and significantly backfired in Taiwan. This result contradicts prominent prior findings. A charge to "protect lives in your family" significantly outperformed placebo in Taiwan and Turkey but saw null effects elsewhere. A message noting that vaccination significantly reduces hospitalization risk decreased signup intent in Brazil and had no significant effects in any other country. Such heterogeneity was the hallmark of the study: some messages saw significant treatment effects in some countries but failed in others. No nudge outperformed the placebo in Russia, a location of high vaccine skepticism. In all, widely touted behavioral nudges often failed to promote vaccine signup intent and appear to be moderated by cultural context.

RESUMEN

PURPOSE: This study aimed to examine whether indirectly deterring elevator use through time-targeted Point-of-Decision Prompts (PODPs) efficiently increased stair usage in a university setting. METHODS: A quasi-experimental design (pre-post design) was employed over 2 weeks in September 2023. Baseline observations were conducted for 1 week prior to signage placement at two locations. The intervention in this study lasted for 1 week, immediately following baseline observations. Three hundred and thirty-one and 384 participants were observed during the baseline and intervention periods, respectively. Logistic regression analysis was used to examine the increase in the act of ascending the stairs. RESULTS: Our intervention, which focused on time-related messages, effectively increased stair usage among university students (coefficient = 0.435, p-value < 0.01). Furthermore, females (coefficient = -0.820, p-value < 0.05) and individuals aged ≥ 30 years (coefficient = 1.048, p-value < 0.01) were notably more likely to be influenced by our intervention than males and individuals aged < 30 years. CONCLUSION: Indirectly discouraging elevator use through time-targeted PODPs may amplify the effects of the previously employed time-related messages. Our findings suggested that a deterrence nudge should primarily be directed towards promoting stair usage among females or individuals aged ≥ 30 years.

RESUMEN

AIM: To explore frail older adults' preferences and needs regarding mobile health (mHealth) exercise interventions in China. Additionally, it sought to identify the nudge strategies necessary for initiating and sustaining exercise behaviours among frail older adults. DESIGN: A qualitative study. METHOD: The semi-structured interviews were conducted between April and May 2024 from two communities in Changsha, China. The data were analysed using a deductive framework analysis aligned to nudge theory, and an inductive thematic analysis to gather relevant needs and preferences. RESULTS: This study involved 14 participants with pre-frailty or frailty, aged 60-82 years (median age of 64 years). While participants were generally receptive to new technologies, lower levels of health literacy and competing priorities often hindered their participation. Three primary functionality requirements were as follows. (1) Profession engagement: tailored exercise prescription, professional and timely feedback and guidance; (2) personalised knowledge encompassing pain management, successful cases and inspiration; (3) beneficial, tailored, dynamic, fragmented, challenging exercise courses. Participants showed positive attitudes towards simplification nudges, gamification nudges, social nudges, trustworthy nudges, reminder nudges, economic nudges, feedback nudges and pre-commitment nudges. Addressing privacy concerns was essential to build trust and acceptance among older adults. CONCLUSION: These findings emphasised the importance of designing mHealth interventions that address frail older adults' specific needs and preferences while incorporating effective nudge strategies to promote engagement and adherence. Future researchers should explore wearables, ChatGPT language models, virtual coaching assistants, exercise snack to further optimise the experience and analyse the effects of nudges in mHealth exercise interventions among older adults. IMPLICATION FOR THE PROFESSION AND/OR PATIENT CARE: Exercise systems or app development for frail older adults should meet three basic functionality and essential nudge strategies. REPORTING METHOD: The consolidated criteria for reporting qualitative research (COREQ) guidelines were used for reporting. PATIENT OR PUBLIC CONTRIBUTION: Older adults' engagement and interview data contribute a lot.

RESUMEN

Previous research has demonstrated the influence of commensal dining between humans on food choices, whereas we conducted two studies to examine how the presence of a robot might influence people's choices between meat-heavy and vegetable-forward meals in imaginary scenarios. In Study 1, participants were instructed to choose three desirable dishes from a set of two meat and two vegetable dishes while they imagined eating alone, with a human, or with a robot. Although the meat dishes were rated as more palatable and pleasant, the female participants chose fewer meat-heavy meals when eating alone or with a robot than when eating with a human, whereas no such effect was observed for the male participants. We also replicated these patterns in Study 2, as the female participants chose fewer meat-heavy meals when eating with a robot and a human than when eating with two humans. Collectively, these findings provide empirical evidence regarding how the presence of a certain robot can influence female consumers' food choices in imaginary scenarios, which has direct implications for the practice of promoting sustainable food choices.

RESUMEN

Purpose This study aimed to investigate the willingness to use and the application interest toward a smoking cessation program flyer among occupational health staff and smokers, utilizing a nudge approach. Methods A control group (typical flyer) and a nudge group (flyer improved according to the Easy, Attractive, Social, Timely (EAST) framework from the control flyer) were established. Occupational health staff and workers with a desire to quit smoking were randomly divided into two groups, and a web survey was conducted. Results Among occupational health staff, the nudge group flyers received significantly higher evaluations with desires "to apply" (control group: 1.7±0.7 vs. nudge group: 3.7±1.2: 5-point scale) and "to recommend to colleagues in the same profession" (control group: 1.7±2.4 vs. nudge group: 6.6±2.4: 11-point scale), and the reading completion rates were 7.0% for the control group vs. 70.7% for the nudge group (p<0.001). Although there was no significant difference in smokers' willingness "to apply" (control group: 2.9±1.2 vs. nudge group: 3.1±1.2: 5-point scale; p=0.388), the nudge group flyer was significantly more likely to be "want to recommend to other smokers" (control group: 4.9±2.4 vs. nudge group: 5.5±2.4: 11-point scale; p=0.032), with reading completion rates of 73.1% for the control group and 87.4% for the nudge group (p=0.001). Conclusion Typical flyers were not preferred by occupational health staff and may not have been effectively promoted to workers wishing to quit smoking. This study suggests that the combination of the EAST nudges could potentially increase the appeal to occupational health staff. To enhance the application interest among workers wishing to quit smoking, introducing other methods such as incentives might be necessary.

RESUMEN

Underutilization of mental health services is a complex problem that requires the investigation of new strategies to facilitate treatment-seeking. Nudging is a relatively new approach which has shown promise in promoting healthy behaviors in a variety of domains, though little work has investigated how nudges may be applied to the initiation of mental health treatment. In this paper, we review the limited work examining nudging related to treatment initiation and discuss findings from a study evaluating the impact of nudges on treatment-seeking. Findings provide insights into the acceptability and efficacy of nudging as a strategy for increasing treatment, and implications for future work exploring this approach for improving treatment access are discussed.

RESUMEN

BACKGROUND: A food environment intervention using nudge tactics was implemented at a hospital convenience store (CVS) in Tokyo to improve employees' eating habits. The objective of this study was to evaluate its effects on the urinary sodium-to-potassium ratio (Na/K), food intake, eating attitude, and behavior. METHODS: Using a pre-post design; the intervention incorporated nudge tactics, healthier options, easy-to-pick food placement, and eye-catching information. We also used price incentives. The primary outcomes included changes in Na/K and sodium and potassium excretion assessed using spot urine samples at health checkups. Secondary outcomes were changes in staff food intake, eating attitude, and behavior which were assessed using questionnaire surveys. All outcomes were evaluated statistically. Furthermore, we investigated how the intervention led to outcomes using path analysis. RESULTS: A total of 140 participant (52men and 88women) were analyzed. Significant changes were observed in Na/K (3.16 to 2.98 in median, p = 0.02) and potassium excretion (43.4 to 45.2 mmol/day in mean, p = 0.03). However, sodium excretion did not change significantly. The intake of fruits and dairy products increased with improved self-efficacy. The most influential factor for lowering Na/K and increasing potassium excretion was information from the CVS; purchasing "balanced meals" to lower Na/K and salads to increase potassium excretion were second. CONCLUSIONS: Food environment intervention using nudge tactics can improve staff's food intake and lower Na/K. TRIAL REGISTRATION: Registration number: UMIN000049444 (UMIN-CTR).

RESUMEN

Nudges can be an effective strategy to promote vaccination. However, it is necessary to better identify the characteristics of nudges that produce the strongest effects and how they interact with individuals' attitudes. Here we sequentially test the effectiveness of three nudge characteristics (framing, nudge type, and presentation modality) and the role of participants' attitudes toward Covid-19 vaccination, social solidarity and authoritarianism in vaccination decisions. In studies 1-4, participants were presented with a nudge manipulating a target characteristic (e.g. positive/negative framing, nudge type) and measuring willingness to vaccinate and related variables compared a control nudge. Study 5 used a single combined nudge reflecting the combination of successful nudges in previous studies. Results over all studies show that nudging has unreliable effects while vaccine attitudes are more reliably linked to all measures of vaccines willingness. These results suggest that attitudes play a more reliable role on effective adoption of vaccinations.

RESUMEN

Nudge theory proposes using subtle interventions to encourage individuals to make better decisions. The aim of this study was to evaluate the effectiveness of the Nudge theory in plaque control and assess caries experience among third-grade primary schoolchildren with refugee and immigrant backgrounds in Mashhad, Iran. Moreover, Afghan and Iranian schoolchildren were compared to assess differences in oral health outcomes. A quasi-experimental field trial was conducted in three public primary schools, comprising 309 participants approximately 9 years old. Interventions were randomly assigned to three schools: School I Messages based on Social Norms (MSN), School II Messages based on Fear of Negative Outcome (MFNO), and School III control group (C). MSN and MFNO received customized motivational video clips at baseline, while C only received Oral hygiene instruction (OHI). All participants received OHI, a brush, and toothpaste. Baseline plaque index (PI) and caries experience in primary and permanent dentition (dmft/DMFT) were recorded. PI was reassessed at two weeks, two months, and six months post-intervention. All data were subjected to statistical analysis. The mean PI decreased significantly in all three groups at the two-week follow-up (p < 0.01). The PI improvements declined over a six-month follow-up period in all groups, and the mean PI difference after six months compared to the pre-intervention was significant only in MSN and MFNO (p < 0.01), while C reverted almost to the pre-study level. Schoolchildren with at least one filled tooth or Iranian nationality showed a greater PI reduction (p < 0.01, p = 0.05). The overall mean ± SD dmft and DMFT were 4.24 ± 2.11 and 1.70 ± 1.24, respectively. Among all the examined participants, 32 (10.40%) individuals were caries-free. The mean dmft was statistically significantly higher in Afghan children than in Iranians (p = 0.01). MSN was more effective on PI reduction in the short term, while MFNO was more long-lasting. Using the Nudge theory via visual aids was more effective in motivating children to perform better oral self-care than solely traditional OHI.

RESUMEN

RATIONALE: The escalating dissemination of health misinformation on social media platforms poses a significant threat to users' well-being. It is imperative to identify the types of health misinformation that are more susceptible to widespread dissemination and to explore strategies to curb its spread. METHOD: This study designed a 2 (emotional appeal type: positive vs. negative) × 2 (fabricated source type: pseudo-common vs. pseudo-authoritative) × 2 (accuracy-nudge label: No vs. Yes) online between-subjects experiment controlling for factors such as e-health literacy, prior sharing experience, and personal involvement. A snowball sampling approach was used to recruit 1952 participants through social media, resulting in a final sample of 1393 valid responses. RESULTS: Compared to positive emotional appeal and pseudo-common sources, negative emotional appeal and pseudo-authoritative sources resulted in higher levels of sharing intention. Under the condition of negative emotional appeal, the promotion effect of pseudo-authoritative sources on sharing intention was intensified. The accuracy-nudge intervention could significantly mitigate this tendency. The underlying mechanisms revealed more details: both negative emotional appeals and pseudo-authoritative sources increased the perceived credibility of health misinformation, thereby increasing users' sharing intention. However, in contrast to pseudo-authoritative sources, excessive negative emotional appeal induced vigilant verification behavior among users, which reduced sharing to some extent. Adding an accuracy-nudge label to health misinformation reduced users' misguided trust in health misinformation features and stimulated information verification, ultimately reducing health misinformation sharing intention. CONCLUSIONS: Negative emotional appeal and pseudo-authoritative sources can enhance the perceived credibility of health misinformation, thereby strengthening the sharing intention of social media users. Therefore, health misinformation with negative emotional appeal and pseudo-authoritative sources is more likely to be widely shared. The accuracy nudge intervention can trigger users' information verification behavior, suppress the persuasive effects of the misinformation features mentioned above, and help prevent the spread of health misinformation on social media.

RESUMEN

OBJECTIVES: We aimed to assess the clinical effects of dietary education intervention utilizing the nudge strategy in individuals with type 2 diabetes mellitus (T2DM). BACKGROUND: The global prevalence of T2DM and its associated complications presents a significant health challenge. While the benefits of dietary education intervention for blood glucose management are widely acknowledged, patients often struggle to adhere to dietary recommendations. The implementation of the nudge strategy may offer a promising solution to change unhealthy dietary behavior and enhance diabetes control among individuals with T2DM. METHODS: This is a sub-study within a broader cluster-randomized trial that evaluated the effects of nudge-based dietary education and traditional dietary education intervention. Measurements of HbA1c, fasting blood glucose (FBG), body mass index (BMI), blood lipid levels, blood pressure, dietary behavior, and diabetes distress were assessed at baseline and 3 months after the intervention in 147 individuals with T2DM from six primary care practices in Beijing, China. RESULTS: All outcome measurements were complete at two time points for 134 participants. Results showed that compared to the control group, the intervention group achieved a significantly greater reduction in HbA1c, FBG, BMI, total cholesterol, low-density lipoprotein cholesterol, blood pressure, total energy intake, carbohydrate intake, fat intake, and protein intake and had lower diabetes distress. The intervention group also maintained HDL-C levels and had a significantly greater increase in vegetable intake, while changes in triglycerides were similar in the two groups. CONCLUSION: The present study provides evidence that nudge strategy-based dietary education intervention is effective in improving blood glucose, BMI, blood lipid levels, and blood pressure and facilitating changes in patients' dietary behavior and diabetes distress. These findings suggest that implementing nudge strategies can contribute to the optimization of T2DM dietary management and overall patient well-being.

RESUMEN

Introduction: Antibiotics for open fractures (OFs) administered within 60 min of emergency department (ED) arrival reduce patients' infection risk. We tested a novel method of displaying children's drawings to prompt clinicians to improve adherence with early antibiotics for OFs. Methods: Registry-based pre- (January 1, 2016-June 30, 2019) and post- (July 1, 2019-March 31, 2022) intervention at a level 1 trauma center. In July 2019, children's artwork depicting OF was displayed in the ED alongside OF guidelines and E-mailed to faculty and residents. Primary outcome: proportion of OF patients who received antibiotics within 60 min of arrival. Time to antibiotics was calculated from ED arrival to time-stamped administration in the electronic health record. We compared time to antibiotics as continuous variables between the two groups. Proportions are presented with percentages and 95% confidence interval (CI); continuous variables as median and quartiles. Chi-square or Mann-Whitney U-tests were used for group comparisons. Results: Five hundred fifty-four total OF patients were identified (excluded: transferred = 1, ED death = 4, unclear time to antibiotics = 11); 281 pre-implementation and 257 post-implementation. The median age was 34 years (quartiles 24 and 46). Trauma mechanisms of injury included 300 blunt (56%) and 238 penetrating (44%). Gustilo OF classification by type were as follows: 71% I, 13% II, 15% III, 1% unclassified. There was a significant difference (P = 0.001) in both percentage of patients who received antibiotics within 60 min (58%, 95% CI, 52%-63% vs. 79%, 95% CI, 74%-84%) and time to antibiotics (median: 46 min vs. 25 min) between pre- and postphases, respectively. Conclusions: Children's artwork in our ED improved adherence with OF guidelines and decreased time to antibiotics.

RESUMEN

Plastic pollution is increasingly becoming a threatening problem worldwide, with highlighted health risks associated with plastic waste incineration. Among the immediate measures to address this problem, proper recycling of polyethylene terephthalate (PET) bottles is a pertinent strategy. Considering the urgent need for administrative-led reforms, we assessed the separation rates of PET bottle caps and labels by 125 administrative staff in a government office of a prefectural in Japan during a four-day period; only 59.3% (48/81) of the pet bottles had both caps and labels removed and properly separated to each trash can. One potential solution for the low separation rate is the use of nudges, which are effective methods for promoting behaviors such as healthy actions. Since both health and environmentally conscious behaviors involve choices across different time points, leveraging insights from nudges developed in the field of health behavior to environmental behaviors is considered crucial, even from a health promotion perspective.

RESUMEN

AIMS: In China, more than 30% of patients have not initiated treatment within 30 days of HIV diagnosis. Delayed initiation has a detrimental influence on disease outcomes and increases HIV transmission. The study aims to evaluate the effectiveness of a nurse-led antiretroviral therapy initiation nudging intervention for people newly diagnosed with HIV in China to find the optimal intervention implementation strategy. METHODS: A Hybrid Type II sequential multiple assignment randomized trial will be conducted at four Centers for Disease Control and Prevention in Hunan, China. This study will recruit 447 people newly diagnosed with HIV aged ≥18 years and randomly assign them into two intervention groups and one control group. On top of the regular counselling services and referrals, intervention groups will receive a 4-week, 2-phase intervention based on the dual-system theory and the nudge theory. The control group will follow the currently recommended referral procedures. The primary outcomes are whether treatment is initiated, as well as the length of time it takes. The study outcomes will be measured at the baseline, day 15, day 30, week 12, week 24 and week 48. Generalized estimating equations and survival analysis will be used to compare effectiveness and explore factors associated with antiretroviral therapy initiation. Both qualitative and quantitative information will be collected to assess implementation outcomes. DISCUSSION: Existing strategies mostly target institutional-level factors, with little consideration given to patients' decision-making. To close this gap, we aim to develop an effective theory-driven nudging strategy to improve early ART initiation. IMPACT: This nurse-led study will help to prevent delayed initiation by employing implementation science strategies for people newly diagnosed with HIV. This study contributes to the United Nations' objective of ending the AIDS pandemic by 2030. TRIAL REGISTRATION: Chinese Clinical Trial Registry ChiCTR2300070140. The trial was prospectively registered before the first participant was recruited. PATIENT AND PUBLIC INVOLVEMENT: The nudging intervention was finalized through the Nominal Group Technique where we invited five experts in the related field and five people living with HIV to participate.

RESUMEN

Background: Gambling disorder (GD) is a pressing public health concern with significant societal costs. The recently developed nudge theory, which is rooted in behavioral economics, aims to influence the decision-making behaviors of individuals by implementing changes in the environment. Aim: This scoping review aims to synthesize the literature on nudge theory as it relates to gambling. Methods: This scoping review accords with the Arksey and O'Malley framework, as refined by Levac et al. It includes only articles from peer-reviewed journals that focus, as main themes, on both nudge theory and gambling. The final study selection includes six articles. Results: The scoping review process led to studies explaining how (1) nudges aim to prod people toward healthier gambling choices, fostering the adoption of more responsible gambling practices, and (2) some gambling features, called dark nudges (or sludges), exploit and harm the decision-making processes of people who gamble. Conclusion: This scoping review highlights the fact that many stakeholders are involved in the field of gambling, and that better cooperation between them would promote safer and more responsible gambling practices. Future research is also needed to empirically test nudges to develop a better understanding of their impact on those who gamble.

RESUMEN

Behavioural nudges are often criticised because they "work best in the dark". However, recent experimental evidence suggests that the effectiveness of nudges is not reduced when they are delivered transparently. Most people also endorse transparent nudges. Yet, transparent nudging may undermine human autonomy-a minority may oppose to being nudged and feel manipulated, even if they know what is happening. We propose an alternative way of maintaining autonomy that is not reducible to transparency: individuals can be asked if they consent in advance to being nudged. To assess whether consensual nudges are effective, we ask consent from 1518 UK citizens to be nudged. Subsequently, we default all participants into donating to a charity of their choice, irrespective of self-reported consent. We find that the default nudge is equally effective for both consenting and non-consenting individuals, with negligible difference in average donations. However, non-consenting individuals report higher levels of resentment and regret and lower levels of happiness and support compared to the consenting group. Based on these findings, we argue that ignoring consent can have serious ethical ramifications for policy-making with nudges.

RESUMEN

Hypertensive patients often do not make the most favorable choices and behaviors for managing disease. Behavioral economics strategies offer new ideas for guiding patients toward health behavior. The scoping review aimed to summarize behavioral economics strategies designed to improve hypertension self-management behaviors. A literature search was conducted in September 2022 using the following electronic databases: Embase, Medline, CINAHL, PsycINFO, Web of Science, Cochrane Library, CNKI, Wan Fang Database for Chinese Periodicals, and CBM-SinoMed. We screened the literature for experimental studies written in Chinese or English reporting on BE strategies designed to improve self-management behavior in hypertension. We searched 17 820 records and included 18 articles in the final scoping review. We performed qualitative synthesis by the categories of choice architecture. The most common BE strategies were those targeting decision information and decision assistance, such as changing the presentation of information, making information visible, and providing reminders for actions. Most strategies targeted BP, diet, medication adherence, and physical activity behavior. Ten out of 18 studies reported statistically significant improvement in self-management behavior. Further research on BE strategies should focus on addressing the challenges, including changing the decision structure, encompassing a more comprehensive range of target behaviors, and examining the long-term effects of BE strategies.

Self-management of hypertension is a long-term effort, but people often make bounded rational decisions and act in ways that deviate from health goals. Behavioral Economics (BE) strategies make small changes in the decision-making environment to alter choices, steering individuals' behavior consistent with their goals or preferences. We summarized the BE strategies to improve self-management behavior in hypertension and described the study results using the categories of choice architecture. We found that the most widely used BE strategy is changing the presentation of information in the decision-making environment. Most BE strategies positively affect the target behaviors, which have the potential of BE strategies to enhance self-management behavior for hypertension. Further research is needed to identify the origins of these strategies, modify decision-making structures, and incorporate a broader range of health behaviors to showcase the practicality and sustainability of implementing BE strategies.

RESUMEN

Current concerns regarding the health and environmental consequences associated with excessive meat consumption have underscored the importance of guiding consumers towards more sustainable diets. Given this perspective, this study seeks to evaluate the effectiveness of tailored informative messages in shaping consumer behaviour, particularly within the framework of replacing meat with mushroom-based alternatives. Additionally, it explores the factors influencing informative message effectiveness. An experimental online survey was conducted on a sample of 951 Italian consumers. Specifically, the sample was divided into three groups, of which 309 individuals formed the control group, 311 participants received informative messages on the health risks associated with red meat consumption, and 331 participants received informative messages emphasizing the environmental damages linked to red meat consumption. In both treatments, there was support for mushroom-based alternatives. Analyses included subgroup assessments, tests to verify treatments effectiveness, along with OLS regression to pinpoint variables influencing message effectiveness. The results underscore a fair positive impact of the two informative messages (mean scores: 8.75 for health message; 7.01 for environmental message). Noteworthy psychosocial variables, including lifestyle patterns, nutritional perceptions, and ecological attitudes, emerged as determinants in shaping consumers' food choices. While health-related messages exhibit marked influence, the nuanced landscape of diverse drivers and barriers necessitates judicious communication strategies. These insights bear significance for policymakers, health professionals, and marketers, offering guidance for interventions that effectively influence consumer behaviour toward more sustainable and healthier food practices.

RESUMEN

BACKGROUND: Hand hygiene (HH) among health care workers (HCWs) is crucial in preventing infections in nursing homes. However, HH compliance (HHC) among HCWs remains low. This study aimed to investigate the effect of feedback lights on HCWs' HHC. METHODS: A 5-month interventional study was conducted in 3 wards in a nursing home in Denmark. During the intervention period, a green light with a smiley appeared on the alcohol-based hand rub (ABHR) dispensers when HCWs used the ABHR, acknowledging HCWs for using the ABHR. HHC was monitored using an automatic HH monitoring system (AHHMS). RESULTS: A total of 64 HCWs were enrolled. The AHHMS collected 23,696 HH opportunities in apartments and dirty utility rooms. Overall, HHC in the apartments increased from 50% at baseline (95% CI: 48, 53) to 56% (95% CI: 54, 58) during the intervention. However, the increased HHC level was not sustained during follow-up. CONCLUSIONS: The AHHMS enabled the assessment of the intervention. We found a significant effect of light-guided feedback in the apartments. However, the increased HHC was not sustained after the light was switched off.
