Plain-English summary
Researchers have adapted a questionnaire to help dog owners assess chronic elbow osteoarthritis (a type of joint disease) in their pets, specifically for Swedish dogs. They tested this new version with two groups: one with 117 dogs that had moderate elbow dysplasia (a developmental issue affecting the elbow joint) and another with 146 healthy dogs. The questionnaire was found to be effective in distinguishing between the two groups and showed good reliability and validity, meaning it accurately measures what it’s supposed to. This tool can now be used by veterinarians and researchers to track the progression of elbow osteoarthritis in dogs. Overall, the adaptation of the questionnaire was successful and can be helpful in both clinical and research settings.
Abstract
BACKGROUND: Owner questionnaires may be used to assess osteoarthritis (OA) in dogs. The validated American College of Veterinary Surgeons' (ACVS) Canine Orthopaedic Index Questionnaire quantifies quality of life in dogs with orthopaedic disease. This index was modified and translated into Swedish and evaluated for validity, reliability and sensitivity. One group with confirmed moderate elbow dysplasia (n = 117) and one healthy control group (n = 146) without radiographic elbow disease and without lameness were included. Telephone interviews with the dog owners were conducted throughout the study using owner-completed questionnaires. RESULTS: A 16-item questionnaire developed from an initial data set including 22 items, were able to differentiate between the affected group and the control group with good readability. Validity was measured through factor analysis which yielded a three-factor model accounting for 66.3% of the variance. Cronbach's α was 0.89 for the total instrument, > 0.7 for stiffness, lameness and function, but < 0.7 for quality of life. Based on the process the modified questionnaire can be used in Swedish, as the ACVS COI, to make intra-patient comparisons and evaluation of disease progression. CONCLUSIONS: A sound owner-completed questionnaire translated into Swedish and modified, able to differ healthy dogs from dogs suffering from chronic osteoarthritis is presented. Performed statistical analysis show the items of the instrument to be reasonable and have high construct validity. The questionnaire may be used in the clinical setting and for research.
