Item Influencing Employees Intention to Talk about Safety(2020-07-03)The majority of workplace accidents are caused by human error. The need for action to mitigate this issue has led to the development of a variety of safety programs. One such program is SafeStart. One of SafeStart’s instruments is the introduction of so-called Rate-your-State talks; short conversations, guided by a protocol. They are suggested in order for individuals to reflect on their mental state and become aware of associated risks in order to prevent casualties. The study at hand aimed to increase employees’ intention to start Rate-your-State talks by means of a flyer, presented as part of an online survey. Modelled around the Theory of Planned Behavior, a variety of techniques were used, aiming to influence attitudes and social norms. The intervention did not have a significant effect on employees’ intention to engage in Rate-your-State. Suggestions for future research are given.Item The Influence of Taste-Focused Food Labelling on Vegetarian and Vegan Food Choice(2020-07-17)Animal-based product have a large negative impact on our environment. A sustainable diet entails reducing one’s meat consumption and instead choosing vegetarian and vegan alternatives. This research studied the impact taste-focused labelling has on an online sample’s preference of vegetarian dishes over non-vegetarian dishes and vegetarian dishes with regular names both in a menu-choice task and a binary choice task. It was expected that participants would choose more vegetarian dishes with tasty names over non-vegetarian dishes and regularly-named vegetarian dishes. The results revealed non-significant findings for the menu choice task and part of the binary choice task. Significant results were found for the contrast between taste-focused vegetarian dishes and regular-labelled vegetarian dishes. Taste-focused labelling had no effect on preference of vegetarian dishes on a menu, but it did decrease choice of meat dishes in a binary choice task. Keywords: Sustainability, vegetarian food choices, taste-focused labellingItem Het Effect van Kennis over Milieugevolgen en Sociale Cohesie op het Verminderen van Bijplaatsingen(2020-07-03)Ondanks dat het plaatsen van afval naast ondergrondse containers negatieve gevolgen heeft voor bewoners, laten burgers deze terugkerende gedraging zien. Bijplaatsingen zijn dan ook een veelvoorkomend probleem binnen vele gemeenten in Nederland. Aan dit gedrag liggen verschillende psychologische gedragsfactoren ten grondslag die per situatie kunnen verschillen. Uit eerder onderzoek is gebleken dat het beïnvloeden van een enkele factor het aantal bijplaatsingen kan verminderen. De vraag is wat het effect is van het combineren van meerdere psychologische gedragsfactoren in een interventie op het verminderen van het aantal bijplaatsingen. Vooronderzoek heeft middels een vragenlijst gekeken welke psychologische factoren in de wijk Spijkerkwartier in Arnhem een rol spelen bij het bijplaatsen van afval. Hieruit kwamen onder andere de variabelen kennis over de milieugevolgen en sociale cohesie/controle naar voren. Aan de hand van een online interventie is onderzocht of deze variabelen van invloed zijn op de intentie om afval in de container te deponeren. De resultaten toonden aan dat er geen hoofdeffecten zijn gevonden van de onafhankelijke variabelen kennis over de milieugevolgen en sociale cohesie/controle. Ook is er geen significant interactie-effect gevonden tussen deze variabelen op de afhankelijke variabele, de intentie om afval in de container te deponeren. Wel is er een significant verschil over tijd gevonden, en was de intentie om afval in de container te deponeren groter in de nameting dan in de voormeting. Vervolgonderzoek moet uitwijzen of deze resultaten ook gelden wanneer daadwerkelijk gedrag wordt gemeten in een veldonderzoek.

Based on the results, a process model was developed and three predictors were selected; the desire to master the material, the extrinsic motivation by academic rewards, and the experience with the lecturer. These three predictors were manipulated in an intervention in the second study by the use of a video. The previous lecture attendance was included as a covariate. The intervention did significantly increase the lecture attendance. A significant effect of the previous lecture attendance on the current attendance was also found. The intervention group and the control group differed significantly in their desire to master the material and the experience with the lectures but not in their extrinsic motivation. The desire to master the material and the experience with the lecturer therefore predict lecture attendance. Additional research is needed to replicate these findings and to develop effective interventions in order to increase attendance on the long-term.

The sample consisted of 108 Dutch students. The study used a 3x2 experimental design with three conditions (2 intervention and a control condition) and used a pretest-posttest measurement. Students in both intervention groups were requested to form a handwashing implementation intention by either an affiliative or an authoritative agent. No significant effects were found for the intervention group on improving handwashing outcomes. A statistically significant t-test suggests the affiliative agent was considered more persuasive on average, but no mediation effect for persuasiveness, and no moderation effect for cultural orientation were found. Implications and suggestions for future research are discussed.
