## TL;DR

This study finds that people's understanding of medical aid in dying laws in the U.S. varies based on socioeconomic and demographic factors.

## Contribution

The study identifies socioeconomic and demographic predictors of certainty about medical aid in dying (MAID) laws in the U.S.

## Key findings

- Lower socioeconomic status is linked to lower odds of correctly identifying MAID legality.
- Non-Hispanic Black individuals and those with less education are more likely to incorrectly state MAID is illegal in their state.
- Longer duration of MAID legality in a state is associated with greater awareness of the law.

## Abstract

Medical Aid in Dying (MAID) is a legal medical option for terminally ill patients in a growing number of U.S. states, covering over one-fifth of the population. Using a national convenience sample of 3,221 U.S. adults in states where MAID is legal (n = 2,159) and not legal (n = 1,062), this study examines predictors of certainty regarding MAID legality (correctly identifying legality, incorrectly identifying legality, or not knowing). Controlling for sociodemographic factors and attitudes toward MAID, lower socioeconomic status was significantly associated with lower odds of correctly identifying MAID legality nationwide. Compared to financially “comfortable” individuals, those with “enough” (AOR: 0.71, p < 0.001) or “not enough” (AOR: 0.61, p < 0.001) to make ends meet had lower odds of correctly stating MAID is legal anywhere in the U.S. Similarly, those with some college (AOR: 0.75, p < 0.01) or a high school education or less (AOR: 0.66, p < 0.001) were less likely to correctly identify MAID legality. Being non-Hispanic Black (AOR: 0.62, p < 0.05), having a high school education or less (AOR: 0.52, p < 0.001), and reporting financial insecurity (AOR: 0.63, p < 0.05) were associated with incorrectly stating MAID was illegal in their state. In states where MAID is legal, longer duration of legality was associated with greater awareness (AOR: 1.06, p < 0.001). These findings suggest that certainty about MAID laws varies by socioeconomic and demographic factors, which may have implications for informed consent and patient-centered end-of-life decision-making.
