The experimental group will receive a brief overdose prevention education intervention and be issues naloxone upon discharge from jail.

Evaluate an overdose prevention education with incarcerated people living with HIV/AIDS.

The scale is adapted from the Opioid Overdose Knowledge Scale (OOKS). OOKS subscales measure overdose risks, signs, actions to take in a witnessed overdose, & naloxone use. It has 4 multiple choice questions, 4 forced-choice questions, and 6 true/false statements. Each correct answer is 1 point and incorrect answers are 0. Subscale ranges are 0-9 for overdose risks, 0-10 for signs, 0-11 for actions to take in a witnessed overdose, and 0-15 for naloxone use. The total score range is summed from subscale scores from 0 to 45, with higher scores indicating greater knowledge. The adapted scale assesses the same domains and consists of 4 multiple choice questions, 1 forced-choice question, and 6 true/false statements. Each correct answer is 1 point and incorrect answers are 0. Subscale ranges are 0-5 for overdose risks, 0-4 for overdose signs, 0-5 for overdose actions, and 0-6 for naloxone use. Scores are summed for a total number of 20 points, with higher scores indicating greater knowled

The scale is adapted from the Opioid Overdose Attitudes Scale (OOAS). OOAS subscales measure overdose response competence (10 items), concerns (8 items), & readiness (10 items). Likert scale options include "Completely Agree", "Agree", "Unsure", "Disagree", and "Completely Disagree" with a score of 1 to 5 assigned to each item. The total score range on the initial measure is summed from the subscales from 28-140 points (1-50 points on subscale competence, 1-40 points on subscale concerns, and 1-50 points on subscale readiness), with higher scores indicating favorable attitudes. The adapted scale also assesses: overdose response competence (4 questions), concerns (3 questions), and readiness (4 questions). Scoring is identical to the full scale, with possible subscales scores ranging from 1-20 for overdose competence, 1-15 for concerns about responding to an overdose, and 1-20 for readiness to respond to an overdose. Scores are summed for a total score range of 11-55. Higher scores in

Information on any witnessed overdoses since release from jail. The domain of witnessed overdoses is not from an existing scale. It is assessed by asking the following: "Have you seen anyone overdose since you left jail? (To be clear, an overdose means someone is unresponsive or cannot be woken up, collapses, has blue skin color, convulsions, difficulty breathing, loses consciousness, or has a heart attack or dies while using drugs.). Answer options are "yes", "no", and "not sure". Those reporting "yes" are directed to a follow-up question: "How many overdoses have you seen since you left jail?" Answer options range include "1", "2", "3", "4", "5 or more". Additional follow-up questions assess the location, response actions of respondent, response actions of others at the scene, and outcome of the overdose for the victim for the most recently witnessed overdose.
