Developed by Obermiller and Spangenberg (1998) through multiple studies supporting unidimensionality and consistency. Alpha .92 (Hardesty et al. 2002); alphas .808–.86 across three studies (Obermiller et al. 2005). All items are worded in the direction of trust and must be reverse-scored to index skepticism. Item 5 appears truncated in extraction—verify full wording against the original article.
