A Quantitative Study to Assess the Construct Validity of the Prescription Opioid Misuse and Abuse Questionnaire

Member Companies of the Opioid PMR Consortium800 enrolled

Overview

The purposes of this study are to evaluate the validity and reproducibility of the POMAQ to identify opioid abuse and misuse behaviors among participants who have chronic pain which requires long-term opioid use.

The Food and Drug Administration (FDA) has requested, as part of a Post-marketing requirement (PMR) for new drug application (NDA) holders of extended release/long-acting (ER/LA) opioids, to conduct a study to develop and validate a measure of the opioid-related adverse events misuse and abuse among patients with chronic pain prescribed long-term opioid therapy. This measure will be used to assess misuse and abuse in PMR Study 2065-1A and PMR Study 2065-4B. To date, no tool currently exists to address the needs of the PMR except for the Self-Report Misuse, Abuse and Diversion of Prescription (Rx) Opioids questionnaire (SR-MAD) which has undergone several rounds of content validation but requires further validation. The SR-MAD has been substantially modified to meet the needs of PMR Studies 2065-1A and 2065-4B and has been renamed the Prescription Opioid Misuse and Abuse Questionnaire (POMAQ). The POMAQ will undergo content validation via qualitative interviews (Protocol 2065-2A \[Qualitative\]) prior to use in this validation study (Protocol 2065-2A \[Quantitative\]). This quantitative study will seek to further develop and validate the POMAQ following the general tenants according to the Food and Drug Administration (FDA) Guidance for Industry, Patient-Reported Outcome Measures: Use in Medical Product Development to Support Labeling Claims (FDA 2009) which emphasizes the importance of conducting sound psychometric evaluation of patient-reported instruments through quantitative research methods. However, it should be noted that the POMAQ is not a typical PRO measure capturing a specific latent construct and the specified analytic approach to the POMAQ reflects this difference in theoretical frameworks.
