Background/Objectives: This study aimed to translate the Child Coeliac Disease Food Attitudes and Behaviours Scale (Child CD-FAB) into Brazilian Portuguese and to evaluate its reproducibility and internal consistency. Methods: Three steps were carried out: (i) translation and cultural adaptation of the Child CD-FAB into Brazilian Portuguese; (ii) pre-test; and (iii) psychometric evaluation of the Child CD-FAB-BR. The Child CD-FAB was translated and back-translated, and then discussed with and approved by the author of the original instrument. The translated version was tested on five children and adolescents (aged 8 to 16 years) with coeliac disease to assess comprehension. Subsequently, psychometric evaluation used responses from 20 participants with the same characteristics, assessing reproducibility (test–retest reliability) via intraclass correlation coefficient (ICC) and internal consistency via Cronbach’s alpha. Results: The Child CD-FAB was successfully translated to Brazilian Portuguese (Child CD-FAB-BR), and it presented good internal consistency (α = 0.892) and an excellent intraclass correlation coefficient (ICC = 0.923). Conclusions: The Child CD-FAB-BR is the first instrument to evaluate food attitudes and behaviours in Brazilian children and adolescents with CD, showing good psychometric properties. This instrument will support future research and clinical practice by guiding behaviour-based strategies to enhance nutritional education and public policies for this group.
