Psychological determinants of consumption of reusable containers for takeaway food and drinks.

Using food and drink disposable containers has heavy environmental and economic consequences. The widespread adoption of reusable containers is a challenge that requires understanding the psychological determinants and barriers of the behaviour. Two studies were conducted: one with a sample from the general public (study 1, N = 302) and one with respondents having access to a reusable container system at work (study 2, N = 737). Online surveys measured self-reported use of single-use and reusable containers for food and drinks takeaway (studies 1 and 2) and for food delivery (study 1). Stages of change and psychological determinants were also measured to provide behavioural levers. Results indicate that in study 1, most of the sample is aware of the issue associated with single-use containers but has not switched to reusable. In study 2, most respondents say they are already using few single-use and are willing to continue, particularly for drinks to go. Thus, accessibility at the workplace to a reusable container system is associated with higher stages of change. However, many respondents are also in the preactional phase for food takeaway, that is, willing to change but have not started yet. In both studies, perception of control on the behaviour and volitional variables are positively associated with stages of change. This suggests that making reusable containers easier to use and helping individuals plan how and when they can do it could encourage behaviour change.

Sexual and Reproductive Health: How Can Situational Judgment Tests Help Assess the Norm and Identify Target Groups? A Field Study in Sierra Leone.

Sexual and reproductive health is a challenge worldwide, and much progress is needed to reach the relevant UN Sustainable Development Goals. This paper presents cross-sectional data collected in Sierra Leone on sexual and gender-based violence (SGBV), family planning (FP), child, early and forced marriage (CEFM), and female genital mutilation (FGM) using an innovative method of measurement: situational judgment tests (SJTs), as a subset of questions within a larger survey tool. For the SJTs, respondents saw hypothetical scenarios on these themes and had to indicate how they would react. The objective is to give an impression of beliefs and norms on specific behaviors, which provide insights for social and behavior change interventions. Data was collected by enumerators traveling to villages randomly selected in six districts of the country. The sample is composed of 566 respondents. Results show that FGM in particular seem to be a priority topic, in comparison to the other topics for which the norms seem to be stronger against those practices. Age differences emerged and suggest priority groups to be targeted (e.g., on the topic of female genital mutilation, younger female respondents, and older male respondents gave the lowest coded responses which reflected to less appropriate behavior in our coding). In terms of validity of the measurement methods, situational judgment test answers correlated positively with other items in the survey, but the magnitude of the association is often small, and sometimes not significant. Thus, more studies are needed to further explore the validity of this measure by comparing against a reference value. Using SJTs could complement other data collection tools to perform community assessment, and orient the direction of the program in its planning phase.

Does a Low-Cost Act of Support Produce Slacktivism or Commitment? Prosocial and Impression-Management Motives as Moderators.

Increase or decrease in subsequent action following a low-cost act of support for a cause can be predicted from both commitment theory and the slacktivism effect. In this paper, we report on three studies that tested type of motivation (prosocial vs. impression management) as a moderator of the effect of an initial act of support [wearing a badge (S1) and writing a slogan (S2 and 3)] has on support for blood donation. Small-scale meta-analysis performed on data from the three studies shows that activating prosocial motivation generally leads to greater support for the cause after an initial act of support compared to the control condition, while the effect from impression-management motivation can either be negative or null.

Fear appeals to promote better health behaviors: an investigation of potential mediators.

Background: Fear appeals are widely used in health communication, despite conflicting views on their effectiveness. Unresolved issues include possible mediation mechanisms and the effect of defensive reactions aimed at controlling a perceived danger. Methods: The present study compared the impact of three versions of an existing online course on how to prevent noncommunicable diseases. Participants, recruited in South America via a crowdsourcing platform, were divided randomly between three versions of the course - 'threat only'/'threat plus coping information'/'coping information plus threat' (reverse order). We then asked them to complete a questionnaire measuring perceived efficacy, perceived threat, defensive reactions, and intention to change unhealthy behaviors. Results: Using a serial parallel mediation model to test the course's impact on our dependent variables did not reveal any significant differences between the three versions. Perceived efficacy was positively associated with intention to change behavior, as well as with lower suppression, lower reappraisal, and greater denial. Suppression was the only defensive reaction to be associated with intention to change behavior: greater suppression was linked to less intention to change. Conclusions: Our results open interesting perspectives for research into defensive reactions.

Do Environmental Prompts Work the Same for Everyone? A Test of Environmental Attitudes as a Moderator.

The extant literature has focused either on personal variables or on situational factors to explain pro-environmental behavior despite several calls to integrate both. The present research addresses this integration call by testing the interaction between environmental attitudes and situational prompts on pro-environmental behavior. Three experimental studies manipulate the presence/absence of pro-environmental prompts, measure environmental attitudes, and investigate the effect of both variables on behavior. Study 1 showed a simple effect: participants with higher levels of pro-environmental attitudes (compared to those with lower levels) performed more energy saving behavior in the presence of prompts. However, in the absence of prompt, none of the participants performed the behavior, which prevented us from statistically testing the interaction. Studies 2 and 3 were conducted with a similar design: main effects of attitude and prompts were obtained, but the interaction was not found. A Bayesian analysis of the data suggested more evidence toward the null hypothesis of no interaction between environmental attitudes and situational prompts.
