PMID 33935116WHAT IT FOUND
The AMIS-II interview showed consistent scores and was linked to parents' earlier reports of skills and responsibility in young adults with spina bifida.
Age, sex, and ethnicity were not associated with independence scores.
Key findings
01The AMIS-II total score and subscales produced consistent scores (α = 0.90–0.95), including Hispanic/Latino young adults (total α = 0.94; subscales α = 0.88–0.92).
02Parent-reported communication, home living, and money-management skills were associated with the AMIS-II social communication, household skills, and managing money items; parent-reported medication responsibility was not associated with the AMIS-II medication item.
03Age, sex, and ethnicity were not associated with AMIS-II scores, while more severe gross motor functioning was associated with less independence.

What it does not show
Only 64 young adults completed the AMIS-II interview, and the authors said the sample was too small for factor analysis, so the measure's underlying structure is not settled. The sample was limited to ages 18–25, which may explain why age was not associated with self-management when earlier studies included adolescents. Parent AMIS-II reports were not collected at Time 5, so parent and youth disagreement about self-management could not be checked. Cognitive functioning was not measured, so its possible influence on self-management ratings was not tested. The medication and social communication items had the lowest item-to-total correlations, so those items may need modification for emerging adults. Fathers' medication responsibility subscale had low internal consistency, so father-reported medication findings are weak.
Declared interests
The authors reported no conflicts of interest.
The easy way to misread this
Do not conclude that the AMIS-II improves self-management or predicts health outcomes. It was tested as a measurement tool in 64 young adults with spina bifida, not as an intervention, and the authors did not test whether AMIS-II scores predict future complications or transition to adult health care.
