a

PTSD Checklist for DSM-5.

b

Alcohol Use Disorders Identification Test, alcohol consumption questions (AUDIT-C).

c

At least one occasion in the past year of 6+ drinks.

d

Mean and SD represent PTSD symptom severity scores using the PTSD Checklist for DSM-5; range = 0 – 80.

e

DSM-IV criteria.

f

Alcohol Use Disorders and Associated Disabilities Interview Schedule (AUDADIS-5) – includes assessment of PTSD based on DSM-5 criteria.

g

Sample size estimated by assuming half of the sexual minority sample were women, and half of the sexual minority women were bisexual. Only the total sexual minority participant sample was reported (n = 3,204). We only used the proportion of the bisexual sample, since proportion of PTSD and alcohol use disorder were higher in the bisexual sample and provide a more robust comparison.

h

Estimate from a graph.

i

At least one occasion in the past year of 5+ drinks.
