^aPatient Reported Outcome Measurement Information System (PROMIS) short forms Alcohol Use 7A, Anxiety 8A, Anger 5A, and Sleep Disturbance 8A.

^bAlcohol Use questionnaire only filled out by those who indicated that they had consumed alcohol in the past 30 days, which consisted of n = 21 (46.7%) with a service dog and n = 14 (50.0%) on the waitlist.

^cFor participants with a service dog, this continuous variable represents time elapsed since receiving a service dog; For participants on the waitlist, this variable represents time since applying and being placed on the waitlist to receive a service dog.
