Use this screening instrument to select participants most likely to benefit from peer education intervention (PEI).
Publisher StatementParticipants who endorse 3 or more items at the high risk level (e.g. share syringes half the time or more), and no more than 2 items at the lowest risk level (e.g. never share syringes) are classified as high risk. Using the baseline CIDUS 3 data, in a logistic regression predicting high-risk classification (most likely class is high risk) from the proposed screening criteria, sensitivity was 87.5%, specificity 96%, PPV 90%, and NPV 95%; 94% of participants were correctly classified.
