Making known one's end-of-life (EOL) care wishes via the processes of advance care planning (ACP) and advance directive (AD) completion is associated with many positive outcomes for patients including lower healthcare costs, greater patient-provider relationship satisfaction, increased quality of life, and more. Despite these benefits, fewer than 30% of patients in the United States engage in ACP or complete ADs. These low numbers are most likely due to several causes, including low self-efficacy and low motivation to engage in the process. Several researchers have examined the persuasive power of using worry to motivate patients to engage in preventive health behaviors. The present study expands upon this body of literature by examining patient intentions to seek information related to ACP and AD after being exposed to stimuli intended to arouse differing levels of worry regarding bad EOL outcomes. Participants (N = 804) were randomly assigned to either the high worry, low worry, or control group and asked to complete a questionnaire examining beliefs and information seeking intentions regarding ACP and AD completion. Additionally, to control for participants' level of trait worry, each participant completed the Penn State Worry Questionnaire, which was treated as a covariate in the final analysis. A repeated measures MANCOVA found a statistically significant increase for the worrying conditions on the participants' intention to seek information about ACP and ADs from time 1 to time 2 for those in the worry experimental conditions. However, those in the control group did not show a statistically significant increase. Additionally, exposure to the high worry condition was predictive of engaging in actual information seeking behavior about EOL care. Results of the experiment indicate worry is associated with greater motivation to engage in information seeking about ACP and AD. This study contributes to the literature on worry as a persuasive mechanism to motivate patients to engage in important preventative health behaviors.
