A psychometric evaluation of the Family Decision-Making Self-Efficacy Scale among surrogate decision-makers of the critically ill. Palliat Support Care. 2019 Nov 08;:1-7 Authors: Pignatiello GA, Irani E, Tahir S, Tsivitse E, Hickman RL Abstract OBJECTIVES: The purpose of this study was to report the psychometric properties, in terms of validity and reliability, of the Unconscious Version of the Family Decision-Making Self-Efficacy Scale (FDMSE). METHODS: A convenience sample of 215 surrogate decision-makers for critically ill patients undergoing mechanical ventilation was recruited from four intensive care units at a tertiary hospital. Cross-sectional data were collected from participants between days 3 and 7 of a decisionally impaired patient's exposure to acute mechanical ventilation. Participants completed a self-report demographic form and subjective measures of family decision-making self-efficacy, preparation for decision-making, and decisional fatigue. Exploratory factor analyses, correlation coefficients, and internal consistency reliability estimates were computed to evaluate the FDMSE's validity and reliability in surrogate decision-makers of critically ill patients. RESULTS: The exploratory factor analyses revealed a two-factor, 11-item version of the FDMSE was the most parsimonious in this sample. Furthermore, modified 11-item FDMSE demonstrated discriminant validity with the measures of fatigue and prepar...
