Abstract
Chronic critical illness is expected to impact 600,000 Americans annually by 2020. Often, the chronically critically ill (CCI) experience persistent cognitive impairment. Thus, family members serve as surrogate decision makers (SDMs) to make complex healthcare decisions for their loved one. Decision support interventions have been developed to meet the informational needs of SDMs during this distressing period. However, past decision support interventions have not been effective in meeting the informational needs of SDMs. Current decision support interventions have not evaluated unique behavioral and cognitive factors that may influence an SDM's readiness to engage in decision making. Therefore, this study applied the Strength Model of Self-Control and Cognitive Load Theory to address the following aims: (1) explore how cognitive load differs among SDMs receiving two multimedia decision support interventions; (2) evaluate the association between self-regulation (emotion regulation and cognitive regulation) and cognitive load; and (3) evaluate the relationship between cognitive load and decision making readiness (decision making preparation, self-efficacy, and fatigue).
