Preliminary Evidence Supporting Validity and Reliability of the Assessment for Appropriate Use of Opioids for Long-Term Care

<b>Objective</b> This study aimed to provide preliminary evidence supporting the validity and reliability of the 10-item Assessment for the Appropriate Use of Opioids in Long-Term Care. <b>Design</b> This analysis utilized baseline data from the study titled Testing the Pain Clinical Practice Guideline Using the Evidence Integration Triangle. <b>Setting</b> Six nursing homes were included in the study.Residents: Residents were eligible if they were 65 years of age or older and had evidence of pain or were receiving treatment for pain. The sample included 24 residents who were on opioid medications. <b>Intervention/Procedure</b> The authors collected data from electronic health records using research evaluators. Evidence of validity was established based on the internal structure of the measure and its relationship to other variables. Reliability was assessed through item reliability and internal consistency. <b>Main Outcome Measures</b> Descriptive variables included age, cognitive status, comorbidities, race, ethnicity, marital status, and education. Pain assessment was based on the Minimum Data Set: (1) a verbal response item and (2) four objective items. The Assessment for Appropriate Use of Opioids in Long-Term Care consists of 10 items evaluating the appropriate use of opioids. <b>Results</b> The mean age of the residents was 71.8 years (SD = 9.9). The majority were female (62%), White (54%), and non-Hispanic (92%). Evidence of validity was observed based on the internal structure of the measure, item fit, and associations with other variables. Reliability was supported by internal consistency and inter-rater reliability. <b>Conclusions</b> The study provided preliminary evidence of validity and reliability; however, future testing is needed with a larger, more heterogeneous sample.
