Abstract
The Companion Animal Semantic Differential consists of 18 bipolar semantic differential word pairs for assessing the respondent's perception of a childhood companion animal. The measure was administered by questionnaire to a sample of 188 students. The Cronbach alpha internal reliability coefficient was 0.90 for the 18-item scale. The construct validity of the scale was indicated by its significant correlations with the evaluative factor of the Pet Attitude Scale and the childhood Companion Animal Bonding Scale of .31 and .54, respectively. Factor analysis identified a short 9-item form as a one-dimensional measure of the respondent's affective attitude toward his or her pet. The short form's Cronbach alpha was .88 and its correlations with the affective factors of the Pet Attitude Scale and the childhood Companion Animal Bonding Scales were .24 and .50, respectively. The measure is included.
