Break the Cycle: Prevention for Reducing Initiation Into Injection Drug Use


Break the Cycle is a two-session, one-on-one, in-person intervention study designed to reduce the role persons who inject drugs (PWID) play initiating non-PWID into injection drug use. Study implementation is at two sites: New York City and Tallinn, Estonia. At baseline, quantitative data are collected via a structured computer-assisted personal interview, after which the intervention is conducted. At the 6-month follow-up, a modified version of the interview is repeated. The study uses a pre- versus post- design to compare the proportion of participants who helped with first injections, and who promoted injecting among non-PWID, in the 6 months prior to baseline with the proportions at the 6-month follow-up. Break the Cycle intervention follows a motivational interviewing approach to enhance current injectors' motivation and skills to avoid helping with and promoting first injections among non-PWID. The intervention's core is a discussion between an interventionist and each participant on the following eight topics: the participant's first time injecting drugs; the participant's exposures to situations where helping with others' first injections is an option, and the extent to which they have helped; PWIDs' behaviors that might encourage non-PWID to inject for the first time; the range of risks associated with injection drug use; role-playing scenarios in which the participant develops behaviors and scripts for avoiding or refusing requests to initiate others into injection drug use; role- playing talking with other PWID about not encouraging non-PWID to start injecting; imparting safer injection practices when helping with a first injection seems like the best option; and receiving training in and using Narcan to reverse overdoses.
