Background Capability well-being captures well-being based on people’s ability to do the things they value in life. So far, no capability well-being measures have been validated in dermatological patients. Objectives To validate the adult version of the ICEpop CAPability measure (ICECAP-A) in patients with dermatological conditions. We aimed to test foor and ceiling efects, structural, convergent and known-group validity, and measurement invariance. Methods In 2020, an online, cross-sectional survey was carried out in Hungary. Respondents with self-reported physiciandiagnosed dermatological conditions completed the ICECAP-A, Satisfaction with Life Scale (SWLS), WHO-5 Well-Being Index and two dermatology-specifc measures, Dermatology Life Quality Index (DLQI) and Skindex-16. Results 618 respondents (mean age 51 years) self-reported a physician-diagnosed dermatological condition, with warts, eczema, onychomycosis, acne and psoriasis being the most common. ICECAP-A performed well with no foor and mild ceiling efects. The violation of local independence assumption was found between the attributes of ‘attachment’ and ‘enjoyment’. ICECAP-A index scores correlated strongly with SWLS and WHO-5 (rs=0.597–0.644) and weakly with DLQI and Skindex-16 (rs=− 0.233 to − 0.292). ICECAP-A was able to distinguish between subsets of patients defned by education and income level, marital, employment and health status. Multigroup confrmatory factor analysis indicated measurement invariance across most of these subgroups. Conclusions This is the frst study to validate a capability well-being measure in patients with dermatological conditions. The ICECAP-A was found to be a valid tool to assess capability well-being in dermatological patients. Future work is recommended to test measurement properties of ICECAP-A in chronic infammatory skin conditions.
