Creation of the European Portuguese version of the Glasgow Composite Measure Pain Scale – short form (CMPS-SF) and initial psychometric evaluation

The animals in the sample had a mean body weight of 23.2 ± 4.2kg and a mean age of 5.9 ± 3.1 years. Sixty-three procedures were classified as soft tissue, 5 as orthopedic, 27 as mild, and 41 as moderate. Significant differences were observed in median scores between soft tissue and orthopedic cases and between mild and moderate cases. Median pain scores decreased with time. We presented the initial validation of the European Portuguese version of the CMPS-SF in the Portuguese language. It provides clinicians with a valid tool to assess acute pain in dogs. Further studies are required to determine if the present results can be replicated across samples, submitted to a larger range of surgical procedures, and in different clinical settings.
