A questionnaire study was conducted amongst an opportunity sample (N= 100), including participants who were recruited through a combination of the confederate’s social networking sites and the university’s research voluntary participation system (a participation system, where students voluntarily sign up to participate in research,in exchange for credits)(Mage=23.82, SD=9.32; 81% females).
Participants were asked to fill in a 20min questionnaire on their opinions regarding their attitudes towards personal care products, specifically moisturisers.
The only criterion for participation was that participants should use a moisturiser, so the scenarios would be relevant for them.
Females were over-represented in our sample, probably because primarily women use moisturisers (Wu et al., 2010).
