Abstract

This dissertation proposed to establish a post-acute care continuum measurement system by creating an item bank that linked existing instruments. We linked two instruments measuring physical activities of daily living in the Veterans healthcare system, Functional Independence Measure which is used in Inpatient Rehabilitation Facilities and the Minimum Data Set which is used in the Community Living Centers. The objectives included: (a) creating an IRT-based item bank, (b) creating IRT-based short forms from the item bank, (c) comparing measurement precision of converted scores from varied FIMTM and MDS forms, and (d) comparing accuracy of the varied forms in generating functional related groups (FRG). We found measurement precision and accuracy decreased as the number of item decreased. FIM short forms (SFs) had similar precision and better accuracy than MDS SFs. The MDS_13-item form had acceptable precision and accuracy for generating FRGs, supporting developing a continuity measurement by linking existing instruments.
