Abstract
BackgroundManagement of prescription opioids misuse and abuse problems among chronic pain patients has been increasingly important worldwide and little literature concerning prescription opioids can be found in mainland China so far.MethodsThe Current Opioid Misuse Measure (COMM) was translated into Chinese following Brislin’s model of cross-culture translation and was completed by a convenience sample of 180 patients with chronic pain recruited from two major hospitals in Jinan, Shandong province. Data were analyzed using internal consistency, test-retest reliability, exploratory factor analysis and confirmatory factor analysis.ResultsThe internal consistency coefficient for the total score of the COMM was 0.85 and item-total correlations of all items were above 0.20. Besides, the test-retest reliability was satisfactory with an ICC of 0.91 (95 % CI = 0.65-0.98). Four principal components were extracted, accounting for 65.30 % of the variance, and the factor loadings of all 17 items were above 0.40.ConclusionsThe Chinese version of COMM showed satisfactory reliability and validity, and could be used as a screening tool to evaluate and monitor current aberrant drug-related behavior among Chinese patients with chronic pain.
Highlights
Management of prescription opioids misuse and abuse problems among chronic pain patients has been increasingly important worldwide and little literature concerning prescription opioids can be found in mainland China so far
In the United States, prevalence of chronic opioid use increased from 3 % in 2003 to 4.5 % in 2007, and multiple studies in the literature have reported an association between opioid prescribing and overall health status, with increased disability, medical costs, subsequent surgery, and continued or late opioid use [2]
As a selfreport screening instrument, the Current Opioid Misuse Measure (COMM) provides an estimate of the patients “current” status and its items capture a 30-day period
Summary
Management of prescription opioids misuse and abuse problems among chronic pain patients has been increasingly important worldwide and little literature concerning prescription opioids can be found in mainland China so far. Physicians usually lay emphasis on pain treatment, in view of the sever impairment both physically and psychologically brought by chronic pain, like activity limitation in daily life, depression, anxiety and anger, which leads them to ignore the potential aberrant drug-related behaviors occurring during the process of pain treatment. Such phenomenon arouse our attention and inspire our interests on conducting this research, with the aim of introducing an opioid screening tool and investigating the current status of aberrant drug-related behavior in Chinese patients with chronic pain
