The Companion Animal Bonding Scale: Internal Consistency and Factor Structure When Administered by Telephone

The performance of the 8-item Companion Animal Bonding Scale as a self-report behavioral measure of the human-animal relationship when administered as part of a telephone interview is described. For 784 respondents Cronbach alpha for internal consistency was .74 and the SPSS for Windows Principal Components factor analysis of its internal structure yielded two factors which accounted for 55% of the scale's variance. These results are similar to the scale's Cronbach alpha of .82 and the first two of the three factors which accounted for 56% of the variance when the scale was included in a written questionnaire.
