Objective To investigate the scaling properties of the Subjective Index of Physical and Social Outcome (SIPSO) after stroke in survivors to hospital discharge, unselected by age. Design Factor, Mokken, and Rasch analyses of the SIPSO using data from a prospective observational cohort study. Setting Three acute care hospitals. Participants Consecutive admissions (N=312) with acute stroke, unselected by age. Interventions Not applicable. Main Outcome Measures Patient- or proxy-reported SIPSO, collected by postal survey 6 months after stroke. Results Complete SIPSO questionnaires were returned by 166 of 268 survivors (median age, 72y; interquartile range, 66-81y). Factor and Mokken analyses supported both 1- and 2-factor solutions. Fit to the Rasch model for the 10-item scale was poor (χ2 test for item-trait interaction, χ2=69.6; P<.001 differential item functioning by sex and age was demonstrated for the physical subscore dealt with through creation of super items resulting in a good fit to rasch model p=".67)," ordered thresholds targeting latent trait reasonable separation reliability index social no or sex. local dependence items. thereafter were ordered. poor .67> Conclusions The 10-item SIPSO is a valid ordinal scale in a population including older stroke survivors. A physical and social subscale structure is also supported. Subscales can be manipulated to fit the Rasch model, and a conversion table for conversion to an interval scale is provided. The social subscore has poor separation reliability, limiting its use in older stroke survivors. |
