Score equivalents computed from SCI-FI Basic Mobility will be useful for researchers comparing functional levels in SCI to those observed in other clinical and nonclinical groups (eg, in comparative effectiveness research). The linkage between PROMIS PF and SCI-FI Basic Mobility was considered satisfactory for group-level usage. Comparisons of actual vs linked PROMIS PF scores and test characteristic curves suggested the fixed-parameter method provided slightly more precision than the separate calibration method. It is based on advanced 3D solid and surface modeling methods that maintain accurate representations as you progress from design. Of the 3 banks, only SCI-FI Basic Mobility could be linked with sufficient precision to PROMIS PF. formZ pro is a powerful 3D design application featuring a variety of modeling personalities and tools with an easy to use interface to express and communicate your imagination. Sixteen items common to SCI-FI and PROMIS and verified as free of differential item functioning were used as anchor items to implement the methods. The data were used to attempt to link 3 SCI-FI banks to the PROMIS PF metric via 2 item-response theory methods: fixed-parameter calibration and separate calibration. SCI-FI item banks (including 30 items from the PROMIS PF item bank) were administered to 855 adults with SCI as part of the original SCI-FI development study. Three SCI-FI item banks (Basic Mobility, Fine Motor Function, Self-Care), PROMIS PF v1.0 item bank. Observational study SETTING: Six SCI Model Systems rehabilitation hospitals in the United States.Īdults with SCI (n=855) and healthy individuals (n=730) (N=1585). To link 3 Spinal Cord Injury-Functional Index (SCI-FI) item banks (Basic Mobility, Fine Motor Function, Self-Care) to the Patient-Reported Outcome Measurement Information System (PROMIS) Physical Function (PF) metric.
