“…In line with previous findings, scale length, number of response categories, and selection rates also had an effect on the outcome variables (e.g., Crișan et al, 2017;Zijlmans, Tijmstra, van der Ark, & Sijtsma, 2018). The item scalability coefficient is equivalent to a normed item-rest correlation, which, in turn, is used as an index of item-score reliability (e.g., Zijlmans et al, 2018). Therefore, it is not surprising that overall scale reliability decreased as the item scalability coefficients decreased.…”
