According to cognitive-dissonance theory, performing counterattitudinal behavior produces a state of dissonance that people are motivated resolve, usually by changing their attitude be in line with behavior. One the most popular experimental paradigms used produce such change is induced-compliance paradigm. Despite its popularity, replication crisis social psychology and other fields, as well methodological limitations associated paradigm, raise concerns about robustness classic studies this...
A clear picture of people's adoption protective behaviours, and a thorough understanding psychosocial correlates in the context contagious diseases such as COVID-19, is essential for development communication strategies, can contribute to fight against epidemics.In this paper, we report survey on recommended behaviours before during epidemic. We also assessed demographic correlates, beliefs (towards COVID-19 towards SARS-CoV-2 transmission, social dilemma variables, perceived external cues)...
It is unclear whether knowledge about a customer's current sustainable behaviours, such as their choice of lightbulbs or travel mode, allows us to predict the behaviours they will carry out in future. We address this large longitudinal study (N = 2177) where participants provided self-reports on electricity-, heating- and mobility-related consumption at two separate times, three years apart. The results highlighted high level temporal consistency, whereby carrying one behaviour predicted...
Promoting vaccine uptake is challenging. This research aimed to experimentally test the effect of communication strategies on influenza intention. We hypothesized that descriptive norm level (10%-50%-90% others vaccinated) intention would vary according whether benefits are focused individual (self-interest motives) or (herd-immunity motives). In particular, we predicted low and high levels norms be detrimental in herd-immunity condition (inverted-U pattern). contrast, should increase...
Growing awareness of humanity's impact on the environment raises question how best to encourage pro-environmental actions. Numerous campaigns have been created convince people adopt environmentally friendly everyday behaviors, with varying success. The difficulty may be due, at least in part, huge gap between these small individual actions and high-level goals, such as "saving planet," often used incentives. We tested this hypothesis via four experiments. Studies 1 2 showed that goals were...
The extant literature has focused either on personal variables or situational factors to explain pro-environmental behavior, despite several calls integrate both. present research addresses this integration call by testing the interaction between environmental attitudes and prompts behavior. Three experimental studies manipulate presence/absence of prompts, measure attitudes, investigate effect both Study 1 showed a simple effect: participants with higher levels (compared those lower levels)...
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.
There is a risk that people vaccinated against COVID-19 will drop or reduce their precautionary behaviours (i.e., phenomenon of homeostasis). Our aim to assess the occurrence this effect in cohort UK participants who were interviewed 141 days before and 161 after start vaccination programme.Of 765 could be followed up programme whose status was known, 178 had not received any injection 583 more less advanced process (one vs. two doses since than 14 days). The frequency assessed at both times...
Descriptive norm effect has been explained in terms of either normative or informative social influence. This research investigates another possible mechanism the case collective goals. Because changing one's behaviour — e.g., to protect environment will be effective only if other people also change their behaviour, number influence outcome expectancy for that behaviour. Hence, we postulated descriptive on adoption a pro-environmental is mediated by expectancy. Two studies showed intention...
Texting blood donors to thank them for saving lives has generated great enthusiasm, but do these messages increase donor return rates? In fact, nobody knows. We addressed this lack of evidence by conducting a randomized experiment measure the effectiveness thank-you messages. Our involved assigning either control condition (no message) or an experimental (thank-you message), and assessing differences in rates six ten months later. also measured potential mediators with online survey sent...
Organic waste sorting impacts greenhouse gase emissions and energy consumption. Because the recycling rate of organic is often lower than other types (e.g., paper, glass), behavioral sciences are needed to promote this behavior. Relative general behavior, which has been more studied, literature scarce on psychological determinants This study aims fill gap examine perspectives non-recyclers recyclers using a publicly funded kitchen scraps bin called P'tite Poubelle Verte (PPV, French for...
Increase or decrease in subsequent action following a low-cost act of support for cause can be predicted from both commitment theory and the slacktivism effect. In this paper, we report on three studies that tested type motivation (prosocial vs. impression management) as moderator effect an initial [wearing badge (S1) writing slogan (S2 3)] has blood donation. Small-scale meta-analysis performed data shows activating prosocial generally leads to greater after compared control condition,...
Abstract Background Retention of first‐time donors is pivotal for blood collection centers. The present study built on research showing the importance donor identity among regular and sought to compare effectiveness various communication strategies return rate. Study Design Methods Postal letters were sent a large sample whole ( N = 1219) few weeks following their first donation. Four versions this letter differently constructed in way boost acquisition (i.e., by including information about...

Using food and drink disposable containers has heavy environmental economic consequences. The widespread adoption of reusable is a challenge that requires understanding the psychological determinants barriers behaviour. Two studies were conducted: one with sample from general public (study 1,
Abstract Background Informing humanitarian action directly from community members is recognized as critical. However, collecting insights also a challenge in practice. This paper reports data collected among and Red Crescent volunteers the occupied Palestinian territory. The aim was to test collection tool, situational judgment tests (SJTs), collect around three themes. Methods SJTs covered violence prevention, road safety, environmental pollution (waste), were constituted of hypothetical...
Conformity to descriptive and injunctive norms has been explained by informational normative social influence. We argue that in addition these two types of influence, outcome expectancy can mediate norms’ impact on people’s intentions the case collective behaviours such as hand washing prevent virus spread. Two studies manipulate norm type (descriptive vs injunctive) level (low high) show their effects intention perform behaviour. In Study 1 (N = 216), was positively influenced associated...
Background Programmes for collective smoking cessation, based on the British model Stoptober, are proposed by public health units in many countries. There is a need data estimating rate at which participants these programmes successful quitting smoking. We report prospective study carried out as part of large-scale cessation programme conducted Switzerland 2017. Methods 1112 among 7008 smokers enrolled were recruited before start attempt. Continuous abstinence was measured 10 days, 3 months...
Sexual and reproductive health is a challenge worldwide, much progress needed to reach the relevant UN Sustainable Development Goals. This paper presents cross-sectional data collected in Sierra Leone on sexual gender-based violence (SGBV), family planning (FP), child, early forced marriage (CEFM), female genital mutilation (FGM) using an innovative method of measurement: situational judgment tests (SJTs), as subset questions within larger survey tool. For SJTs, respondents saw hypothetical...
Tobacco consumption during pregnancy has consequences for pregnant women and their fetus, as well the postnatal period. Many stop tobacco pregnancy, but statistics vary about exact proportion, a non-negligible number of them are still smoking at term. Moreover, relapse after birth is frequent. This study aims to provide epidemiological indicators term post-partum in Switzerland, test risks factors associated with term, including Theory Planned Behaviour variables motivational correlates....
