Development of a Canine Care and Welfare Knowledge Scale: Implications for Welfare and Preventing Dogfighting

The objective of this study was to develop a Canine Care and Welfare Knowledge (CCWK) Scale for use in educational intervention development and evaluation and validate the instrument. The study population was 504 children, aged 11 to 19 years old, from Detroit, MI. In this cross-sectional study, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used for scale development. The EFA and CFA of the CCWK Scale revealed a 2nd-order model with 6 factors to be a good fit of the data (chi-square [df = 269] = 433, p < .05, Comparative Fit Index = .94, Tucker-Lewis Index = .93, root mean square error of approximation = .05) with a Cronbach's alpha of .78. The scale is valid and reliable to assess the study population's CCWK.
