We employed item and scale psychometrics (exploratory factor analyses, confirmatory factor analyses and item-response theory statistics) to refine items to a brief scale. Results: Following removal of problematic items (poor retest-reliability or wording, semantic redundancy, differential item functioning, collinearity or rarity) iterative factor analytic procedures identified a 10-item unifactorial scale with good model fit in the total sample (N= 426; CFI = 0.981, TLI = 0.975, RMSEA = 0.057), and among pain (CFI = 0.969, TLI = 0.960, RMSEA = 0.062) and OST subgroups (CFI = 0.989, TFI = 0.986, RMSEA = 0.051). The 10 items provided good discrimination between groups, demonstrated acceptable test-retest reliability (ICC 0.80, 95% CI 0.60-0.89; Cronbach's alpha = 0.89), were moderately correlated with related constructs, including opioid dependence (SDS), depression and stress (DASS subscales) and Social Relationships and Environment domains of the WHO-QoL, and had strong face validity among advising clinicians. Conclusions: The Opioid-Related Behaviours In Treatment (ORBIT) scale is brief, reliable and validated for use in diverse patient groups receiving opioids. The ORBIT has potential applications as a checklist to prompt clinical discussions and as a tool to quantify aberrant behaviour and assess change over time.]]> Sat 24 Mar 2018 07:16:38 AEDT ]]> Comparing treatment-seeking codeine users and strong opioid users: findings from a novel case series https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:23860 Sat 24 Mar 2018 07:12:11 AEDT ]]> Treating codeine dependence with buprenorphine: dose requirements and induction outcomes from a retrospective case series in New South Wales, Australia https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:23970 -1 (mean: 564 mg; 95% confidence interval 431-696 mg). Median buprenorphine dose was 12.0 mg (interquartile range 9.5 mg, range 4-32 mg) at day 7 and 16.0 mg (interquartile range 13.5 mg, range 4-32 mg) at day 28. Buprenorphine doses received were markedly higher than estimated codeine doses based on standard dose conversion tables.Discussion and Conclusions: With increasing presentations relating to codeine dependence, these findings provide important guidance to clinicians. Buprenorphine doses were consistently higher than doses estimated based on the dose of codeine consumed, and were comparable with doses used in the treatment of dependence with heroin and more potent prescription opioids.]]> Sat 24 Mar 2018 07:10:05 AEDT ]]>
