RESUMEN
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.
