Mean age 44.5 (SD 16.7). Diagnostic distribution: stroke 48 (52%); other brain injury 28 (31%); or other neurological condition 16 (17%). Evaluation of convergent and divergent validity; unidimensionality, scaling, reliability (internal consistency and test\u2013retest); responsiveness to change and feasibility of the ArmA were undertaken.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Expected convergent and divergent relationships were seen with the Leeds Adult Spasticity Impact Scale and the Disabilities of Arm Shoulder and Hand (DASH) (rho 0.5\u20130.63). Principal components analysis confirmed that active and passive function formed two separate constructs in each sub-scale. Mokken analysis corroborated the findings of the principal components analysis and demonstrated scaling using the monotone homogeneity model (Item H&gt;0.5 for all items). Cronbach\u2019s alpha was 0.85 and 0.96, respectively, for the passive and active function subscales. Item level test\u2013retest agreement ranged from 92-97.5% (quadratic-weighted Kappa 0.71-0.94). In the subgroup treated for spasticity with botulinum toxin ( n = 58), the ArmA passive function scale identified a significant difference between responder and non-responder groups (Mann Whitney U = 0.85, p &lt; 0.01). Respondents reported the ArmA to be relevant (77%), easy to use (90%) and timely to complete (83% under 10 minutes).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
