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

Purpose: This study examined preliminary psychometrics of the Adolescent/Young Adult Self‐Management and Independence Self‐Report Scale (AMIS II SR). Methods: Adolescents 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. Results: Item‐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. Conclusions: This 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.
