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.]]> Wed 24 Nov 2021 15:52:02 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:44281 Tue 11 Oct 2022 14:41:34 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:12296 Sat 24 Mar 2018 08:10:08 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:17227 Sat 24 Mar 2018 07:59:16 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:44732 Mon 24 Oct 2022 08:28:36 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51584 Mon 11 Sep 2023 14:36:30 AEST ]]>
