“…For example, in a study of 239 patients with depression, perfectionism significantly predicted negative outcome, for both psychological and pharmacological treatments (Blatt, Quinlan, Pilkonis & Shea, 1995). Pre-treatment self-critical perfectionism was significantly associated with negative treatment outcome in 53 patients with chronic pain, even after taking into account pre-treatment levels of depression (Kempke, Luyten, Van Wambeke, Coppens & Morlion, 2014). In anorexia nervosa, perfectionism is associated with poorer outcome after hospital admission (Bizuel, Sadowsky & Riguad, 2001) and with treatment drop-out (Sutandar-Pinnock, Carter, Olmsted & Kaplan, 2003).…”
