“…Empirically, measures of perfectionistic cognitions have been found to be associated with positive and negative automatic thoughts and a ruminative response style, but they have still been found to add incremental validity in predicting psychological distress beyond these variables (Flett, Hewitt, Blankstein, & Gray, 1998;Flett, Madorsky, Hewitt, & Heisel, 2002). Prior cross-sectional studies have found that individuals with more frequent perfectionistic cognitions generally experience higher levels of distress (e.g., Flett et al, 2012;Flett, Hewitt, Blankstein, & Gray, 1998;Stoeber, Kobori, & Brown, 2014) and, in particular, tend to experience enhanced and prolonged reactivity to stressors (Flett, Nepon, Hewitt, & Fitzgerald, 2016).…”
