This dataset contains data from 412 participants recruited through CrowdResearch's Prime Panels in November/December 2019. Measures include Big Three Perfectionism Scale (Smith et al., 2016) to assess rigid perfectionism (e.g., “I strive to be as perfect as possible” and “I do things perfectly, or I don’t do them at all”; 10 items;  = .958) and self-critical perfectionism (e.g., “I am very concerned about the possibility of making a mistake” and “I judge myself harshly when I don’t do something perfectly”; 18 items; alpha = .961; 1 = Strongly disagree to 5 = Strongly agree), the 3-item Kind of Person mindset scale to assess participants’ implicit beliefs [“The kind of person someone is, is something very basic about them and can’t be changed very much,” “People can do things differently, but the important parts of who they are can’t really be changed,” and “Everyone is a certain kind of person and there is not much that can be done to really change that” (all reverse coded; 1 = Strongly disagree to 6 = Strongly agree); Dweck, Chiu, & Hong, 1995; alpha = .860], the 45-item Eating Pathology Symptoms Inventory (EPSI; Forbush et al., 2013 ), which has a series of 8 subscales (Body Dissatisfaction, Binge Eating, Cognitive Restraint, Purging, Restricting, Excessive Exercise, Negative Attitude Toward Obesity, and Muscle Building) as well as a full-scale score (see Table 1). Participants selected the appropriate option from a Likert scale ranging from 0 (never) to 4 (very often) based on their behavior over the past four weeks (Cronbach’s alpha = .953), and demographic information (which was used to compute body mass index).
