Abstract
The Duty of Care in Companion Dog Owners Scale (Glanville et al., 2023) is an original inventory/questionnaire designed to understand the potential drivers of companion dog owner behavior, with implications for improving dog welfare. This 30-item instrument measures a potentially powerful and unique motivator that encompasses both cognitive and affective dimensions, representing the integration of moral obligations and attentive care. The development of the scale was based on Schwartz’s (1977) Norm Activation Model (NAM) and the Pet Care Competency model (PCC; Glanville, Hemsworth, & Coleman, 2020). The scale has been evaluated in a sample of companion dog owners, and its factor structure, reliability, and validity have been reported.

Purpose
The primary purpose of this scale is to understand the potential drivers of companion dog owner behavior, which has significant implications for enhancing dog welfare.
Validity
Construct Validity: The correlations between the duty of care subscales and dog-owner relationship scores were generally weak to moderate. Relationships with attachment to pet scores varied from weak to strong.
Reliability
Internal Consistency: The Cronbach’s alpha coefficients for the subscales ranged from .73 to .87, indicating good internal consistency.
Factor Analysis
Exploratory Factor Analysis: Of the six proposed subscales, four demonstrated psychometrically satisfactory results. These include:
Personal Norms (Duty Beliefs): One factor accounted for 35.8% of the total variance.
Ascription of Responsibility: A single-factor solution accounted for 47.44% of the variance.
Efficacy: One factor accounted for 59.96% of the variance.
Awareness of Need: The final 10-item, two-factor solution (Problem Awareness and Awareness of Impact) accounted for 43.58% of the variance.
Structural Equation Modeling: All items were entered into the Structural Equation Model (SEM) according to the hypothesized model structure. The model demonstrated excellent relationships between model elements and good model fit, with the following fit indices: PCMIN/DF = 1.824, CFI = .947, RMSEA = .043, SRMR = .0458.
Instrument: Duty of Care in Companion Dog Owners Scale
Test Type: Original Inventory/Questionnaire
Format: Most items are rated on a 7-point Likert scale: Strongly disagree, Disagree, Somewhat disagree, Neither agree nor disagree, Somewhat agree, Agree, and Strongly agree. All items, except for the first, from the Ascription of responsibility subscale are rated on a 5-point scale: Not at all responsible, Partly responsible, Somewhat responsible, Very responsible, and Completely responsible.
Language Available: English
Population Group: Human (Male and Female)
Age Group: Adulthood (18 years & older)
Population Details: Respondents are dog owners located in Australia.
Test Methodology: Test Validity, Construct Validity, Test Reliability, Internal Consistency, Factor Analysis, Exploratory Factor Analysis, Structural Equation Modeling.

Items of the Duty of Care in Companion Dog Owners Scale
Number of Items: This measure consists of 30 items.
Subscales: The scale comprises the following subscales:
Duty Beliefs (personal norms)
Problem Awareness
Awareness of Impact
Efficacy
Ascription of Responsibility
Please note, this scale consists of 5 sub-scales which represent distinct aspects of the duty of care model. The items in each subscale can be summed to produce a score for that element but these sub-scale scores are not to be combined. i.e., DO NOT sum all items in the scale for an overall ‘duty of care’ score.
