Validity of self-reported misuse of prescription opioid analgesics.
OBJECTIVE
To determine concurrent validity of self-reported misuse of prescription opioids.


METHODS
Cross-sectional study in five U.S. methadone maintenance programs.


METHODS
92 addicts.


METHODS
Self-reported questionnaire assessing past-month misuse of 14 opioid analgesics, and color photographs of five opioid analgesics with instructions to mark those used in the past month "to get high." Concordance between self-report and photograph endorsement was assessed via Kappa statistic.


RESULTS
29 respondents completed both questionnaire and photograph endorsements. Kappas were 0.62 (OxyContin), 0.59 (methadone), 0.49 (Dilaudid), and 0.46 (generic extended-release oxycodone).


CONCLUSIONS
Good-to-fair concurrent validity of self-reported abuse was seen for OxyContin, methadone, Dilaudid, and generic extended-release oxycodone.
