First, we asked the participants whether they were familiar
with the brand presented on the package they had to evaluate
(yes/no). Then, we asked them to evaluate the sustainability of
the packaging on two Likert scales ranging from strongly disagree
to strongly agree (‘This package is environmentally friendly’, ‘This
is a good example of an environmentally friendly packaging’;
r = 0.85) in order to check whether our manipulation was successful.
We also measured the perceived healthiness of the products on
a Likert scale (‘Eating raisins (chocolate bars) leads to positive consequences
for health in the long run’). In order to test the influence
of packaging sustainability on the dependent variable, participants
had to rate the product on a semantic differential measurement
scale of perceived quality composed of three items adapted from
Sprott and Shimp (2004) (All things considered, I would say that
these raisins (chocolate bars) are globally of: ‘bad quality/excellent
quality’, These raisins (chocolate bars) seem to have: ‘a very bad
quality/a very good quality’, and Globally, this product seems:
‘bad/excellent’; a = 0.76). Finally, because the material and therefore
the appearance of the package were altered, we wanted to
check for possible differences in the attractiveness of the packages.
Attractiveness was measured on a semantic differential scale (‘This
package is: unattractive/attractive’). All measurements were rated
on 7-point scales. These measurements and their descriptive statistics
are summarized
