Validation of the revised Food Neophobia Scale (FNS-R) in the Italian context.

Measuring individuals' level of food neophobia, i.e., the reluctance to eat novel food, is a critical task since it negatively affects diet variety and quality. Using structural equations models, the revised Food Neophobia Scale (FNS-R) was validated with a sample of 711 Italian adults. After deleting 4 items characterized by both low face validity and a suboptimal association with the other items, and after correcting statistically for the acquiescent response-set, the resulting 6-item, fully balanced FNS-R showed a good construct validity. Moreover, it showed the expected positive correlations with General Neophobia and with Disgust Sensitivity. Finally, it resulted invariant across participants' genders, age classes, and levels of education, and across methods of administration (paper-and-pencil and on-line). Strong points and possible developments of the study are discussed.
