Measured variable

As the main outcome Variable to approximate the risk-perception of the participants, we measure the Assessment on 4 different 7-point bipolar Likert-scales: -An affective scale (very positive – very negative), based on the holistic affect scale (Slovic & Peters, 2006; Van Der Linden, 2015): The participants should rate whether they see the product as something positive or negative. -A usefulness scale (not useful at all – very useful): The participants should rate, whether they see the product as something useful. -A concern scale (not concerned at all – very concerned): The participants should rate how concerned they personally are with using the product in their everyday life. -A regulation scale (completely disagree – completely agree): The participants should rate, whether they think it is important to regulate the use of this product. To control the moderating effect of prior knowledge in the following analyses we measure as an additional outcome variable on a 7-point bipolar Likert-scale the subjective prior knowledge on persistent, mobile, and toxic chemicals, on PFAS/forever chemicals and on microplastics (No knowledge at all – A lot of knowledge). To control the moderating effect of trust we measure as an additional outcome variable on a 7-point bipolar Likert-scale the trust of the participants in regulations by the government and in the labelling of product content is recorded (strongly disagree – strongly agree). As a validation of the mediator effect of the object kind the participants are working with, a question, about the amount of body contact while using the specific object, follows. (7-point Likert scale: No body contact at all – A lot of body contact). The last measured variable is the willingness to spend money on a PMT-free Version of the object (The subjects assess with a slider (0%-100%) the additional money they are willing to spend.
