Validity and Reliability of the 8-Item Inventory of Dimensions of Emerging Adulthood in a Sample of Inflammatory Bowel Disease Patients

Abstract

Background and PurposeThe 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).MethodsAn 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.ResultsThe exploratory factor analysis identified a three-factor structure. The three subscales had acceptable internal consistency (α = .74–.86). Two factors (identity exploration/feeling in-between and instability) were associated with demographics. The factors were not associated with clinical characteristics.ConclusionsDevelopmental 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.
