Objective: Children with life-threatening illnesses and their families may face a myriad of medical decisions in their lifetimes. Oftentimes these complicated medical decisions cause disagreements among patients, families, and providers about what is the best course of action. Although no evidence exists, it is possible that conflict may affect subgroups of the population differently. This study aims to investigate how decisional conflict varies among racial and ethnic subgroups. Sample: Two hundred sixty-six surveys were completed with parents whose children have a life-threatening illness. All children lived in Florida and were enrolled in the Medicaid program. The Decisional Conflict Scale, overall and broken down into its five distinct subscales, was used to assess parental decision-making. Descriptive, bivariate, and multivariate analyses were conducted. Subgroup analyses were conducted on Latino respondents. Results: Our bivariate results suggest that minority parents report less Effective Decision Making ( p < 0.05) and report less Support in Decision Making ( p < 0.05) compared to white, non-Hispanic parents. For the subgroup analysis, we found that those who identify as Mexican American and Central/South American report having greater Uncertainty in Choosing Options ( p < 0.05) and less Values Clarity ( p < 0.05) as compared to Puerto Rican or Cuban Americans. Results from the multivariate analyses suggest that those whose primary language is not English are associated with greater Uncertainty in Choosing Options ( p < 0.05). Values Clarity was lower for children who were diagnosed with their life-threatening condition at birth ( p < 0.05) as compared to children diagnosed at a later time. Conclusions: Our study is the first to describe racial and ethnic differences in decisional conflict of parents of children with life-threatening illnesses. Significant differences exist by race, ethnicity, language spoken, and diagnosis time across several subdomains of decisional conflict. These differences are important to address when creating clinical care plans, engaging in shared decision-making, and creating interventions to alleviate decisional conflict.
