Objectives: Individuals with Cystic Fibrosis (CF) may be at an increased risk of developing a range of eating difficulties. Scales designed to measure disordered eating in the general population do not cover CF-specific behaviours resulting in a knowledge gap. The CFEAB was developed as a CF-specific measure assessing eating behaviours and attitudes however little evidence exists regarding its psychometric quality. The aim of this cross-sectional study was to provide a robust assessment of its internal consistency, structural validity, and criterion validity. Methods: One-hundred and thirty-two people with CF completed self-report scales pertaining to mental health, eating disorders, and the Cystic Fibrosis Eating Attitudes and Behaviours (CFEAB). Results: Results of exploratory structural equation modelling indicated that a three-factor structure produced good fit with the 24-item CFEAB but a purified 12-item CFEAB displayed superior fit and internal consistency. Also, the 12-item scale predicted significant amounts of variance for anxiety, depression, and eating disorders showing enhanced relevance for clinical use. Conclusions: These findings add emphasis to the importance of the validation and development of CF-specific measures and the possible inclusion at clinics to help improve CF patient care.
