“…In this study, a total score was obtained by adding the scores from all items in each of the scales, resulting in possible scores from 0 to 216. This scoring method is an established practice (e.g., Cawsey, Reed, & Reddon, 1982), the reliability and validity of the JDI has been well established (Smith et al, 1969), and the JDI is frequently used (Herr et al, 2004). For the combined scores of items from all five scales, Wiener, Muczyk, and Martin (1992) reported an internal reliability coefficient of .86, Sekaran (1986) reported a Cronbach's alpha of .72, and the Cronbach's alpha computed for this sample was .90.…”
