Abstract

Purpose: We investigated the association between stroke diagnosis and psychological distress among adults in the United States.

Methods: This cross-sectional study utilized data from the 2021 National Health Interview Survey, including adults aged 18 years or older. The exposure variable was self-reported stroke diagnosis (yes/no). Propensity score matching (1:1) was performed to create a cohort of 947 stroke survivors and 947 controls. The outcome variable was psychological distress, assessed using the six-item Kessler Psychological Distress Scale and classified as none/low, moderate, or severe. Weighted multinomial logistic regression models were used to examine the associations between stroke diagnosis and psychological distress.

Results: A total of 1894 respondents were included in the study, 19.3 % and 6.4 % experienced moderate and severe psychological distress, respectively. Respondents who experienced a stroke diagnosis had more than twice the odds of experiencing moderate distress (aORmoderate=2.16, 95 % CI: 1.59-2.93) and more than three times the odds of severe distress (aORsevere=3.12, 95 % CI: 1.76-5.49) compared to respondents without stroke diagnosis.

Conclusion: This study addresses an important gap in understanding the emotional and psychological burden among stroke survivors. Future studies should focus on addressing psychological distress in stroke survivors to assess impact on quality of life and outcomes.
