Study to assess multiple psychometric characteristics of the Stroke Impact Scale (SIS), and to identify and remove non-fitting items from the eight domains that make up the SIS. The SIS was developed from the perspective and input of clients, caregivers, and health professionals with stroke expertise, and includes 64 items and assesses 8 domains: (1) strength, (2) hand function, (3) activities of daily living, (4) mobility, (5) communication, (6) emotion, (7) memory and thinking, and (8) participation. Performance on SIS items is self-reported relative to the difficulty experienced by the participant. A total of 696 individuals with stroke who were community-dwelling and independent prior to stroke participated in the study. The SIS was administered during face-to-face interviews with the client. Rasch analysis, which compares the response patterns of individuals to an entire study sample, was performed, and established the validity of the SIS.
