Background Diabetes mellitus (DM) management primarily focuses on improvement in blood glucose concentrations and clinical signs. A tool to assess the psychological and social impact of DM and its treatment on quality of life (QoL) previously has only been validated for feline DM. Hypothesis/Objectives To validate a diabetic pet and owner-centered individualized measure of impact of DM (DIAQoL-pet) for diabetic dogs and their owners. Animals/Subjects A total of 101 owners of insulin-treated diabetic dogs were recruited to complete the DIAQoL-pet. Methods Discussions and pilot surveys with clinicians and owners of diabetic pets led to the design of 29 specific DM-associated QoL questions. Each item was scored according to impact frequency and perceived importance. An Item-Weighted-Impact-Score (IWIS) for each item was calculated, as was an Average-Weighted-Impact-Score (AWIS) by averaging all IWISs. Principal component analysis and Cronbach's a calculation assessed the measure's reliability. Results The DIAQoL-pet showed high reliability (Communalities =0.5; Cronbach's a 0.85). The AWIS was -2.74 +/- 1.7 (mean +/- SD). Areas reported as most negatively impacting QoL included: worry (IWIS +/- SD: -5.92 +/- 4.3), difficulties leaving dog with friends or family (-5.68 +/- 5.1), worry vision (-5.58 +/- 4.6), boarding difficulties (-5.18 +/- 5.2), worry hypoglycemia (-4.95 +/- 4.3), social life (-4.82 +/- 4.4), costs (-4.11 +/- 4.7), and future care(-4.07 +/- 4.6). Eighty-four percent of owners reported negative impact of DM on QoL. Conclusions and Clinical Importance The DIAQoL-pet proved robust when used by owners of insulin-treated diabetic dogs and identified specific areas most negatively impacting dogs' and their owners' QoL. This tool could be used as an additional assessment parameter in clinical and research settings.
