The purpose of this study is to determine the effect that an educational intervention has on patient knowledge of the signs of opioid overdose and appropriate use of naloxone in a suburban outpatient treatment program.

The outpatient Addiction Services program at Linden Oaks will begin implementing an educational program on the signs of opioid overdose and naloxone for all patients who have a diagnosis of opiate dependence in the investigators suburban treatment program. Subjects will be recruited from that population and administered a new, empirically validated scale (i.e. the Opiate Overdose Knowledge Scale; OOKS) both pre- and post-intervention to measure the effect that the educational program has on patient knowledge.

Patients will also be surveyed (i.e. History Survey) about their experiences over the previous 12-months (e.g. exposure to opiate overdoses, access/use of naloxone) prior to treatment; and, this History Survey will then be re-administered by phone, 1-3 months after discharge. The aim is to measure whether education influences patient behavior. Finally, all subjects will be administered an empirically-validated measure to assess subject shame and guilt (i.e. Guilt and Shame Proneness Scale; GASP), and response patterns in their behavior, to evaluate whether shame and guilt predict behavior at follow-up. The investigators will compare to data (i.e. OOKS, GASP, and History Survey) from a historical control group prior to the implementation of the educational program - and, also at 1-3 month follow-up.
