Effectively reducing climate change requires marked, global behavior change. However, it is unclear which strategies are most likely to motivate people to change their climate beliefs and behaviors. Here, we tested 11 expert-crowdsourced interventions on four climate mitigation outcomes: beliefs, policy support, information sharing intention, and an effortful tree-planting behavioral task. Across 59,440 participants from 63 countries, the interventions’ effectiveness was small, largely limited to nonclimate skeptics, and differed across outcomes: Beliefs were strengthened mostly by decreasing psychological distance (by 2.3%), policy support by writing a letter to a future-generation member (2.6%), information sharing by negative emotion induction (12.1%), and no intervention increased the more effortful behavior—several interventions even reduced tree planting. Last, the effects of each intervention differed depending on people’s initial climate beliefs. These findings suggest that the impact of behavioral climate interventions varies across audiences and target behaviors.

There is increasing scientific and public support for the notion that some foods may be addictive, and that poor weight control and obesity may, for some people, stem from having a food addiction. However, it remains unclear how a food addiction model (FAM) explanation for obesity and weight control will affect weight stigma. In two experiments (N = 530 and N = 690), we tested the effect of a food addiction explanation for obesity and weight control on weight stigma. In Experiment 1, participants who received a FAM explanation for weight control and obesity reported lower weight stigma scores (e.g., less dislike of ‘fat people’, and lower personal willpower blame) than those receiving an explanation emphasizing diet and exercise (F_(4,525) = 7.675, p = 0.006; and F_(4,525) = 5.393, p = 0.021, respectively). In Experiment 2, there was a significant group difference for the dislike of ‘fat people’ stigma measure (F_(5,684) = 5.157, p = 0.006), but not for personal willpower weight stigma (F_(5,684) = 0.217, p = 0.81). Participants receiving the diet and exercise explanation had greater dislike of ‘fat people’ than those in the FAM explanation and control group (p values < 0.05), with no difference between the FAM and control groups (p > 0.05). The FAM explanation for weight control and obesity did not increase weight stigma and resulted in lower stigma than the diet and exercise explanation that attributes obesity to personal control. The results highlight the importance of health messaging about the causes of obesity and the need for communications that do not exacerbate weight stigma.

Pressure injuries (PIs) are a common quality indicator for hospital care, and preventing PIs often requires patient engagement; as such, Australian consensus research has recommended that high‐quality education materials be made to patients for PIs via hospital networks. The purpose of the present study was to assess the availability and accuracy of patient education materials on PIs in publicly available hospital websites in Victoria, Australia. Two independent coders assessed 212 websites for content on PI prevention and management, analysing availability and accuracy of PI definitions, risk factors, preventive strategies, referral, visual tools, consumer endorsement, information for family/carers, and translation on community languages. A greater proportion of hospitals did not have any patient education materials on PI prevention publicly available, with private hospitals (compared with public) and metropolitan hospitals (compared to rural) more likely to have materials available on their sites. The available materials contained accurate messages on PI defining characteristics and risk factors for PIs, although there was considerable variability on the availability of other information. Our findings suggest a significant deficit in the availability of educational materials for acute care patients and their families. There is a need for evidence‐based, consumer‐endorsed, uniform materials on all hospital websites to prevent PIs in acute care.
