- Owners’ ability to recognize signs of chronic pain in dogs undergoing pharmacologic and nonpharmacologic pain interventions during a period of physical rehabilitation is not known. This study aimed to compare dogs with and without chronic pain, and to assess the relationship between explanatory factors, including the probability of owners’ response bias induced by pharmacologic and nonpharmacologic pain intervention, and chronic pain in dogs with osteoarthritis (OA). Seventy-one dogs with OA were included in this observational study. Owner-perceived pain interference was measured by Canine Brief Pain Inventory (CBPI) and owner-perceived pain behavior was assessed using Helsinki Chronic Pain Index. A dichotomous variable of Helsinki Chronic Pain Index was used in regression analysis to investigate the association between chronic pain and explanatory factors (body condition, anti-inflammatory medication, animal physiotherapy consultation once or more and owners’ perception of pain interfering). Seventy-five percent of the dogs had ongoing anti-inflammatory medication, 51% of were overweight and 45% had a physiotherapy consultation. Higher levels of overt pain behaviors were reported in items addressing activities. Body condition, physiotherapy consultation and medication were not associated with chronic pain. Odds ratio (OR) and 95% confidence intervals of OR for the CBPI were 1.74 (1.23-2.47) and significantly associated with chronic pain. The adjusted OR of the CBPI did not differ from the crude OR. Owner-perceived pain behavior was not confounded by the dogs’ medication. Results indicated that CBPI was not mediated by the medication. The CBPI pain interference score was not associated with response bias and may be used as clinical outcome measure of chronic pain and pain-related disability in dogs with OA along a period of physical rehabilitation comprising pharmacologic and nonpharmacologic pain interventions.

- BACKGROUND: To evaluate intervention, implement evidence-based practice and enhance the welfare of dogs with naturally occurring osteoarthritis (OA), access to valid, reliable and clinically relevant outcome measures is crucial for researchers, veterinarians and rehabilitation practitioners. The objectives of the present study were to translate and evaluate psychometric properties, in terms of internal consistency and construct validity, of the owner-reported measure canine brief pain inventory (CBPI) in a Swedish sample of dogs with pain related to OA.RESULTS: Twenty-one owners of clinically sound dogs and 58 owners of dogs with pain related to OA were included in this observational and cross-sectional study. After being translated according to the guidelines for patient-reported outcome measures, the CBPI was completed by the canine owners. Construct validity was assessed by confirmatory factor analysis, by repeating the principal component analysis and by assessing for differences between clinically sound dogs and dogs with pain related to OA. Internal consistency was estimated by Cronbach's α. Confirmatory factor analysis was not able to confirm the factor-structure models tested in our sample. Principal component analysis showed a two-component structure, pain severity and pain interference of function. Two components accounted for 76.8% of the total variance, suggesting an acceptable fit of a two-component structure. The ratings from the clinically sound dogs differed from OA dogs and showed significantly lower CBPI total sum. Cronbach's α was 0.94 for the total CBPI, 0.91 for the pain severity and 0.91 for the pain interference of function.CONCLUSIONS: The results indicate that the translated version of the CBPI is valid for use in the Swedish language. The findings suggest satisfying psychometric properties in terms of high internal consistencies and ability to discriminate clinically sound dogs from OA dogs. However, based on the confirmatory factor analysis, the original factor structure in the CBPI is not ideally suited to measure pain related to OA in our sample and the hypothesis of the presented two-factor structure was rejected. Further research needs to be conducted to determine whether the original psychometric results from CBPI can be replicated across different target groups and particularly with larger sample size.

- Reasons for performing study: The Canine Brief Pain Inventory (CBPI) is a caregiver-reported questionnaire designed to assess pain severity and the impact of pain on activities, such as functional movements, in canine osteoarthritis (OA). The English version of CBPI has displayed satisfactory psychometric properties, in canine OA. To be used in another language the CBPI has to be properly translated and tested.Objectives: To report some psychometric properties of a translated version of the CBPI (CBPI-S), in a group of dogs diagnosed with OA.Study design: Observational, cross-sectional.Methods: Twenty-one caregivers of clinically sound dogs and 61 caregivers of dogs with OA were prospectively included in this study. After being translated, according to recommendations for patient-reported outcome measures, the CBPI-S was completed by the caregivers. Construct validity (the ability to measure what it is supposed to measure) was assessed by repeating the principal component analysis and by assessing for differences between sound dogs and dogs with OA using Mann–Whitney U test. Internal consistency (the correlation among items) was estimated by Cronbach's α.Results: Principal component analysis showed a two-component structure (pain severity and impact of pain). Two components accounted for 76 · 8% of the total variance, suggesting an acceptable fit of a two-component structure. Inter-item correlations were good (overall > 0 · 39) and mean inter-item correlation was 0 · 79 for severity items and 0 · 62 for impact items. Clinically sound dogs differed from OA dogs and showed significantly lower CBPI-S total score. Cronbach's α was 0 · 94 for the total CBPI-S, 0 · 91 for the pain severity and 0 · 91 for the impact of pain.Conclusion: Our results supplement the knowledge with the CBPI by verifying the easy to use utility. Also, by repeating satisfying construct validity and high internal consistency of CBPI-S our results indicate that the translated version seems valid for use in another language.Ethical animal research: The study was approved by the Local Animal Ethics Committee in Uppsala. Informed client consent was obtained for all animals used in the study.Sources of funding: This study was funded by Evidensia Djursjukvård, Svelands Stiftelse, Jan Skogsborgs Stiftelse and Agria & Svenska Kennelklubbens Forskningsfond.
