Abstract
BACKGROUND Post-donation regret in family living liver donors can impact their mental well-being. This study examined whether the relationship between post-donation regret and anxiety is mediated by family relationships and a sense of mastery. MATERIAL AND METHODS We conducted a secondary analysis of de-identified cross-sectional data from a prior study that included 124 living liver donors. These donors underwent partial hepatectomy between January 2011 and March 2021 at a tertiary hospital in Seoul, South Korea. The data included demographic and clinical characteristics, along with the results from administering the following measures: the Post-Donation Regret Scale, Family Relationships Index, Pearlin Mastery Scale, and the Generalized Anxiety Disorder-2 scale. RESULTS Among family living liver donors, 5.6% had anxiety after donation. The total effect of post-donation regret on anxiety was significant (B=0.41, p<0.05). However, the direct effect of regret on anxiety was not significant (B=-0.05, p=0.733). Post-donation regret had indirect effects on anxiety, solely through family relationships (B=0.329, 95% CI=0.130, 0.563) and sequentially through family relationships and mastery (B=0.088, 95% CI=0.008, 0.232), even after controlling for sex, age, postoperative complications, years since donation, and recipient's death. In addition, postoperative complication was a predictor of anxiety (B=0.64, p<0.05). CONCLUSIONS Providing family-centered and mastery-enhancing interventions may help alleviate the anxiety of family living liver donors.
