^aIn-person interviews were conducted via structured survey among 120 Vietnamese Americans in Houston from November 2018 through February 2019. On August 25, 2017, Hurricane Harvey made landfall near Rockport, Texas, as a category 4 hurricane.

^bDetermined by logistic regression; P ≤ .05 considered significant.

^cNo. of observations = 119; log-likelihood = −71.12; probability > χ² = .0003; pseudo R² = 0.128.

^dNo. of observations = 118; log-likelihood = −58.73; probability > χ² = .0006; pseudo R² = 0.272.
