measuring a latent variable is generally seen as reliable if the Cronbach's α is
greater than 0.7 (Breakwell, Hammond, & Fife-Schaw, 2006). The four latent
variables of the Cronbach's α were calculated, with each of the corresponding
items having a uniform procedure, as with the attitudes toward healthy eating
questionnaire (Einstellungen zu Gesunde Ernährung or EGE).
Questionnaire II (completed after the eye-tracking presentation):
•

The above-described Hunger and Appetite Scales were included again.

A German questionnaire on attitudes toward healthy eating (Einstellungen zu
Gesunde Ernährung or EGE) was included with four-point categorical
answer options ranging from “does not apply” to “applies” (Diehl, 1980).
The German EGE questionnaire consisted of 30 items that measured four
latent variables: attitudes on the effectiveness of a healthy diet, appreciation
of a healthy diet, practicing a healthy diet, and consumption of a healthy,
low-fat diet. The questionnaire was analyzed for correlations between the
variables from the questionnaire with the eye-tracking data. An instrument
for measuring a latent variable is generally seen as reliable if the Cronbach's
α is greater than 0.7 (Breakwell, Hammond, & Fife-Schaw, 2006). To
examine the reliability (internal consistency) of the questionnaire, the four
latent variables of the Cronbach's α were calculated with each of the
corresponding items.

A shortened form of the German Food Frequency Questionnaire (FFQ) was
adapted for the food pictures in the present study (Haftenberger et al., 2010;
Truthmann, Mensink, & Richter, 2011). This questionnaire was developed to
assess the food consumption of adults in Germany between 2008-2011
