Rasch Model for Assessing Propensity to Entomophagy

Abstract

The Food and Agriculture Organization of the United Nations supports the production of edible insects as a promising and sustainable source of nutrients to meet the increasing demand for animal-derived products by the growing world population. Even if insects are part of the diet of more than two billion people worldwide, the practice of eating insects (entomophagy) raises challenging questions for Western countries where this is not a habit. The research applied the Rasch models and showed that, in the case of hunger or need, 70.8% of the sample declared that they would be willing to eat insects. The willingness to habitually consume and pay for insect food is very low, but the percentages are higher than people who had actually had insect tasting experiences. This demonstrates that a communication process is necessary that aims to overcome psychological/cultural barriers. Only in this way will it be possible to increase the propensity to consume insects.

Rasch Validation of Instrument Measuring Gen-Z Science, Technology, Engineering, and Mathematics (STEM) Application in Teaching during the Pandemic

“…The separation for item and person for the STEM application instrument in the Indonesian context were 4.67 and 3.81, respectively. The great internal consistency of the instrument was demonstrated by the outstanding outputs of reliability and separation, implying that the instrument can effectively divide items and persons into some categories (Iseppi et al, 2021). Again, in this study, some items revealed high ZSTD scores, indicating a significant misfit, which was one type of measure other than MNSQ, point measure correlation, and separation.…”

“…The separation for item (4.67) and person (3.81) for the STEM application instrument in the Indonesian context was good. The excellent results of reliability and separation indicate great internal consistencies of the STEM application instrument (Iseppi et al, 2021).…”

Determinants of Consumers’ Acceptance and Adoption of Novel Food in View of More Resilient and Sustainable Food Systems in the EU: A Systematic Literature Review

“…On the other hand, previous experience with insects tasting or familiarity with the idea of introducing insects as food were found to increase the willingness to try them [56,71,87,88,94,[100][101][102][103] or to positively affect the hedonic evaluation of insect-based products [74,77]. Familiarity was not an important factor in influencing younger consumers' choice of insectbased food, denoting a major openness [80] and curiosity to novel foods [72,77,104].…”

Validation of the Mathematical Modeling Attitude Scale for Malaysian Mathematics Teachers

“…Separation for item and person for the mathematical modelling attitude scale in the Malaysian context were 4.67 and 3.81 respectively. The excellent results of reliability and separation showed that the instrument can separate item and person to some groups very well and show high internal consistencies of the instrument (Iseppi et al, 2021).…”
