• Nudge- und Choice-Architecture-Interventionen können Verhalten beeinflussen, wobei Effektstärken und ethische Bewertung stark vom Kontext abhängen. wird durch A systematic review and meta-analysis of visual cues and primes for nudging consumption-related behaviours. gestützt: Healthy diets are crucial for maintaining overall well-being and reducing risk of health complications. Visual cues and primes are popular implicit nudging techniques for promoting healthier consumption habits. The present review and meta-analysis was conducted and reported according to PRISMA guidelines. It aimed to evaluate the effectiveness of these cues and primes for nudging consumption-related behaviours. Six electronic databases were comprehensively searched for experimental studies on the use of non-marketing-based visual cues/primes on food/beverage consumption. Sixty-six studies from 52 articles were included, resulting in 205 comparisons categorised into seven groups for separate analyses: (1) healthy food- and (2) body-related nudges, and (3) unhealthy food- and (4) body-related nudges, versus neutral controls; (5) mixed-health food- and (6) body-related comparisons; and (7) nudges not inherently health-related. Overall, nudges effectively influenced consumption-related behaviours. Healthier food- and body-nudges encouraged healthier behaviours relative to neutral controls and less healthy nudges, and unhealthy food-nudges, relative to neutral controls. Non-health-related nudges influenced behaviours in the expected direction, relative to comparison/control conditions. Nudge effectiveness, especially for unhealthy food-nudges, was moderated by participant age and weight, nudge timing (prime/cue) outcome measure (intake/choice), health (mixed/healthy/unhealthy), and whether the outcome was real or hypothetical. A range of participant, nudge, and outcome-related mechanisms proposed to underlie nudge effectiveness were also identified. Findings supported the efficacy of visual cues and primes for eliciting changes in consumption-related behaviours, indicating they may be effective for encouraging healthier consumption, when the right nudges are used. Results also indicated that different forms of nudges may be more appropriate in different circumstances (e.g., for different types of participants or food-related outcomes). Further research is needed to thoroughly comprehend the mechanisms underlying these nudges and their effectiveness. DOI: 10.1016/j.appet.2024.107813.

• In-Store-Interventionen wie Platzierung, Hinweise, Defaults oder Choice Architecture können Kaufentscheidungen in Richtung bestimmter Produkte verschieben. wird durch Online grocery shopping before and during the COVID-19 pandemic: A meta-analytical review. gestützt: The COVID-19 pandemic has forced people to limit their physical interactions, which has led to explosive growth in online grocery shopping. However, there is no clear consensus in the retailing literature on whether consumers prefer to buy groceries online. The objective of this current study is to synthesize research about online grocery shopping published before and during the COVID-19 pandemic and to develop a conceptual framework about online grocery purchase intentions and their determinants, the mediation effects of consumers' attitudes, the moderating effects of COVID-19, and control variables. The meta-analysis presents data derived from 50 independent samples with a sample size of 20,538 respondents. Selected determinants were identified as triggers for online grocery purchase intentions, and perceived usefulness and consumer attitude were identified as important mediators between determinants and intentions. The findings clarify the mechanisms behind the increase in online grocery shopping during the pandemic by presenting a decrease in the importance of its strongest determinants (i.e., perceived usefulness and attitude). Based on these findings, we present contributions to theory, managerial implications, and future research directions. DOI: 10.1016/j.tele.2022.101839.

  Wichtig: New approaches to mitigate vaccine hesitancy and improve vaccine uptake are urgently needed. Nudging has shown effective results in several health areas. However, the effectiveness of interventions involving nudge theory in increasing COVID-19 vaccination remains unclear. We searched PubMed, Web of Science, and Scopus for randomized controlled trials published before December 31, 2022, to determine whether interventions involving nudge theory improved COVID-19 vaccination behavior and intent. Risk ratio (RR) and a 95% confidence interval (CI) were used as pooled measures to assess vaccination behavior. Intention to vaccinate was reported in a narrative synthesis. Sixteen randomized controlled trials involving 176,125 participants were included. Interventions involving nudge theory weakly boosted the COVID-19 vaccine uptake rate (RR = 1.21, 95% CI [1.07, 1.36], p < .01). Subgroup analysis showed a weak positive effect of social norms (RR = 2.04, 95% CI [1.61, 2.57]), defaults (RR = 1.32, 95% CI [1.03, 1.69]), and salient reminders (RR = 1.19, 95% CI [1.04, 1.36]). Nudge interventions integrating multiple components were more efficacious in increasing vaccination rates compared to nudge alone. The effect of nudging interventions weakened over time (p < .001). Most studies (10 of 11) involving vaccination intention outcomes showed positive or partially positive results. Interventions involving nudge theory can promote COVID-19 vaccination behavior and intentions. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

  Wichtig: This systematic literature review and meta-analysis investigated the effectiveness of the nudging approach toward sustainable food consumption in the university canteen context. The systematic literature search was carried out in 5 databases, Web of Science, PubMed, Scopus, ProQuest, and the Royal Library, identifying 14 eligible studies and selecting 9 articles containing adequate information for meta-analysis. The nudging strategies were classified using the typology of interventions in the proximal physical microenvironments framework that resulted in 5 different intervention types: availability, position, size, presentation, and information that belonged to either intervention class-altering properties or placement. The study identified presentation, availability, and information as the most promising nudge intervention for achieving sustainable food consumption at the university canteen or similar settings. Nudging by altering the properties had a small effect size (d = 0.16), and nudging by altering placement showed a medium effect size (d = 0.21). Nudging interventions implemented after understanding consumers' current behavior showed positive effectiveness toward sustainable food consumption rather than implementing random nudges. It is important that future studies aim to achieve sustainable food consumption by understanding canteen user food preferences and food choice motives before designing a nudging strategy.

Health policy (Amsterdam, Netherlands). https://doi.org/10.1016/j.healthpol.2021.10.010

  Wichtig: Obesity and overweight conditions have become major health challenges worldwide. The exploration of effective weight loss strategies is essential. Nudges are currently advancing approaches that represent a new and better method for changing the behaviors of people. However, the effectiveness of nudge interventions on weight loss in overweight people who may be obese has not been synthesized in a systematic manner. In this study, a systematic literature search was performed. Only randomized controlled trials (RCTs) were considered. Weighted mean differences (WMDs) and 95% confidence intervals (CIs) were calculated as summary statistics. In total, 25 RCTs involving a population of 5,929 individuals were included. Significant effects of the nudge strategy on weight loss (WMD: -0.96 kg, 95% CI: -1.49 to -0.43), body mass index (WMD: -0.3 kg/m2, 95% CI: -0.41 to -0.19) and waist circumference (WMD: -0.75 cm, 95% CI: -1.23 to -0.27) were observed. The subgroup analysis showed that the reduction in body weight associated with nudge interventions was significant in younger and more obese people. Moreover, the effect of nudge intervention on weight loss weakened over time. Overall, the nudge strategy can promote changes in weight loss, body mass index and waist circumference of adults, albeit at a mild magnitude and in particular types of individuals. Nudge strategies can be recommended to clinical practitioners and policy-makers to promote obesity management.
