Construct validity, sensitivity and specificity of the USCD
Performance-based Skill Assessment 2 in a mixed Portuguese sample
Abstract
This study explores the psychometric properties of the Portuguese USCD
Performance-based Skill Assessment 2 (UPSA-2-PT) in a mixed sample or
Portuguese participants. Inter-rater Reliability and internal
consistency, convergent validity with community integration are
described. A Receiver Operating Curve analysis establishes the
sensitivity and specificity of scores, and an optimal cutoff value of
functional capacity was established for the Portuguese population. These
findings show an excellent the UPSA-2-PT integrity when compared to with
previous studies carried out in Western countries. Thus, this is a
useful tool for research and clinical purposes to practitioners in
several fields that rely on functional assessment.
