CAS has been shown to have good psychometric properties over the course of several studies [6 (link), 8 (link), 9 , 11 , 24 (link), 25 (link)]. It consists of 23 items. The response format for the CAS is a 5-point scale, ranging from 1(strongly disagree) to 5(strongly agree). The CAS measures three dimensions of celebrity admiration that emerged from factor analysis [10 ]. The first subscale is entertainment-social (10 items; e.g., “My friends and I like to discuss what my favorite celebrity has done, alpha = .83), intense-personal (9 items; e.g., “I have frequent thoughts about my favorite celebrity, even when I don’t want to,” alpha = .89), and borderline pathological (4 items; e.g., “I often feel compelled to learn the personal habits of my favorite celebrity;” alpha = .72). High scores on each subscale suggest a person who is strongly attached to a favorite celebrity. Across several studies total scale Cronbach’s alpha values ranged from .84 to .94 [10 ]. Cronbach’s alpha for the CAS in the current study was .89, .87 and .66 for the entertainment-social, intense-personal and borderline pathological subscales respectively. Cronbach’s alpha for the whole CAS was .93.
