Given heightened public attention regarding the opioid epidemic, it is important to better understand parent attitudes and beliefs regarding opioid medications and how these beliefs influence perioperative pain management in the home setting. This presentation will overview the development and psychometric properties of a measure of parent opioid medication beliefs from a survey of 330 parents of children ages 5-17 years. Parents additionally responded to a vignette focused on acute postsurgical pain management, indicating their likelihood and comfort level with opioid medication administration. Results indicated a two-factor solution meaningfully captured parent opioid medication beliefs: one factor focused on parental opioid risk perception and one factor focused on parental worry and hesitancy regarding their ability to accurately assess pain and provide opioid medication. These two factors were only moderately correlated (r = 0.34). Parents who perceived more opioid-related risks and indicated more parental worry around pain medication administration felt significantly less comfortable and thought they were less likely to use opioids for pediatric pain management. Predictive validity of the measure will be assessed in the context of a study enrolling parents of 7-12 year-old children undergoing tonsillectomy who provide baseline and ecological momentary assessment data for 7-days post-surgery (n > 30).
