“…Of the nine studies that did not use a scale to measure the quality of pet ownership, 55.6% collected information about the type of pet owned ( 35 , 41 , 44 , 45 , 53 ) (and/or engagement or interaction with pets (33.3%) ( 44 , 52 , 53 ). For those that used a validated scale, three utilized the Lexington Attachment to Pets Scale (LAPS) ( 34 , 40 , 49 ), three utilized the Comfort from Companion Animal Scale (CCAS) ( 36 , 47 , 50 ), three used the Cat/Dog Owner Relationship Scale (C/DORS) ( 37 – 39 ), one used the Monash Dog-Owner Relationship Scale (MDORS) ( 46 ), one used the Zasloff Pet Attachment Support Measurement ( 32 ), one used the Inclusion of Other in the Self (IOS) scale ( 37 ), one used the Pets in Australia Survey ( 39 ), and one used both the Pet Attachment Survey of the Center for the Study of Human-Animal Relationships and Environments and the Pet Attachment Questionnaire ( 51 ). Those that used a single item to elucidate whether a pet was present, asked: “Do you own an animal (Yes/No)?” And “What type of animal do you own?” Three also used survey questions to ascertain general engagement and relationships with animals, or the impact of pet owners' behaviors on their pets.…”
