Validation of Upper Limb Self-efficacy Test (UPSET-stroke) Using Rasch Analysis

Purpose of the Study: The objective of the study was to validate upper limb self-efficacy test (UPSET-stroke), and determine which of the demographic and clinical characteristics of the participants will predict self-efficacy. Materials and Method: A cross-sectional study whose data was obtained from a Randomized Controlled Trial. The participants were stroke patients (≤4 weeks post stroke). Participants were assessed using UPSET, motor activity log (MAL), upper limb Fugl-Meyer (FM) motor function subscale, and Wolf motor function test (WMFT). The data for the clinical characteristics of the participants was analyzed using descriptive statistics. Additionally, rasch analysis and multiple regressions were carried out to determine the Unidimensionality, and item difficulty of the UPSET; and the variables that will predict self-efficacy respectively after stroke. Results: There were 48 participants in the study with mean age, 57.60±10.27 years. All items are unidimentional except item 16 (Use your hand to open and close the fridge), most of the items are on the easy side of the person-item map and items 1 and 20 are the easiest and the most difficult respectively. Time since stroke and MAL (how well) predicted upper limb self-efficacy. Conclusion: UPSET-stroke is valid instrument for measuring upper limb self-efficacy after stroke.
