Background and purpose: The purpose was to examine the 8-item Inventory of Dimensions of Emerging Adulthood (IDEA-8) among 61 emerging adults (ages 18-29) with the chronic condition of inflammatory bowel disease (IBD).

Methods: An online continence sample of participants' ages 18-29 years with a self-reported diagnosis of IBD completed a questionnaire including IDEA-8, demographic, and clinical characteristics.

Results: The exploratory factor analysis identified a three-factor structure. The three subscales had acceptable internal consistency (α = .74-.86). Two factors (identity exploration/feeling inbetween and instability) were associated with demographics. The factors were not associated with clinical characteristics.

Conclusions: Developmental features of emerging adults, as measured by the IDEA-8 for those with IBD, may retain conceptual consistency with healthy adults, but demonstrate a restructuring in factor analysis.
