BackgroundOne in five adolescents and emerging adults have reported prescription opioid misuse (POM), posing significant risks for opioid-related adverse outcomes. Devising prevention strategies requires a better understanding of the decisional factors underlying risky misuse behavior. This research examined the associations between past opioid use behavior, opioid risk knowledge and perceptions, and intentional POM decisions.MethodsParticipants aged 15-23years completed surveys assessing past prescription opioid use and misuse, opioid risk knowledge, opioid risk perceptions, and pain relief preferences (i.e., analgesic benefit vs. risk aversion preference). The outcome, Willingness to Misuse (i.e., intentional decisions to use a prescription opioid in a non-compliant manner) was measured using hypothetical pain decision scenarios.ResultsSurveys were completed by 972 adolescents and young adults. In total, 44% had taken a prescription opioid and 32% of these reported past POM. Willingness to Misuse was significantly associated with lower opioid misuse risk perceptions (β = .75 [95% CI .66-.86]) and past opioid misuse (β = 1.81 [95% CI 1.13-2.91]) but not simple risk knowledge (β = .81 [95% CI .58-1.11]. The probability of future misuse was highest for those who reported past opioid misuse and had low risk perceptions (58.7% [95% CI 51.3-65.8]) and high pain relief preferences (53.4% [95% CI 45.3%-61.3%]).ConclusionsFindings suggest that simple knowledge of prescription opioid risks is insufficient to curtail misuse among adolescents and emerging adults. Rather, it may be important to heighten opioid risk perceptions and strengthen opioid risk aversion values when prescribing opioid analgesics to better prevent future misuse in this high risk population.Copyright © 2018.
