Adolescent/Young Adult Self‐Management and Independence Self‐Report Scale: Preliminary psychometric findings

Abstract

AbstractPurposeThis study examined preliminary psychometrics of the Adolescent/Young Adult Self‐Management and Independence Self‐Report Scale (AMIS II SR).MethodsAdolescents and adults (N = 159; 13–38 years old) with spina bifida from two clinics and one community sample completed the AMIS II SR. The majority (83%) had myelomeningocele, and about half were female (51.6%). The sample included 44.7% White, 11.3% Black and over one‐third Hispanic/Latino (38.4%) participants. Descriptive analyses and reliability were assessed; a confirmatory factor analysis (CFA) was conducted.ResultsItem‐to‐total correlations support the AMIS II SR total scale (r = .38–.79) and its two subscales: condition (r = .49–.67) and independent living (r = .49–.85). Internal consistency reliability was high (α = .91–.96) for the AMIS II SR total scale and subscales. A higher order CFA model that included independent living and condition self‐management as first‐order factors and a second‐order overall self‐management factor had excellent fit (RMSEA = 0.06; CFI = 0.97; TLI = 0.96). Descriptive analyses findings were reported.ConclusionsThis study provides psychometric evidence for the use of the AMIS II SR total (overall) scale and subscales (condition and independent living) to assess self‐management and independence.
