Instruments to Evaluate Food Neophobia in Children: An Integrative Review with a Systematic Approach

Food neophobia (FN), a frequent disorder in childhood, profoundly impacts the quality of a diet, restricting the intake of nutrients to maintain proper nutrition. Therefore, using the appropriate tools to assess FN in children to promote healthy eating habits is essential. The study aimed to develop an integrative review with a systematic approach to identify the instruments to measure FN in children and analyze their differences. The included studies (n = 17) were more concentrated in Europe, demonstrating the possible lack of dissemination of the topic at a global level. Among the 18 tools, 6 were represented by adaptations of the Food Neophobia Scale (FNS) and the Children’s Food Neophobia Scale (CFNS), and one was the CFNS itself, demonstrating the relevance of these pioneering tools. The need to meet mainly cultural and cognitive criteria led to the creation of other instruments (n = 11). A diversity of approaches concerning the respondents, age range, items, scales, and validation methods was revealed. Modifications to the tools in some nations highlighted their adaptability and effectiveness in addressing regional variations. The instruments can contribute to additional research to help us better understand the prevalence of FN in children, resulting in their health and well-being
