This 6-item interview is focused specifically on prescription opioid use behaviors. It was developed and used in a larger study designed to assess correlates of OxyContin abuse in pain patients prescribed OxyContin, patients treated for OxyContin addiction, and individuals incarcerated for OxyContin-related charges. The original 8-item POMI included questions regarding dose, frequency of use, the need for early refills, a doctor expressing concern of misuse, feeling high from the medication, taking medication due to stress, obtaining prescriptions from multiple physicians, and pain control. It also included a question regarding adequate pain relief to confirm that any increase in prescription use reported was not due to inadequate pain control.
