“…First, perfectionistic behavior can act as a core vulnerability (Hewitt & Flett, 2002) or transdiagnostic factor (Bieling et al, 2004; Shafran & Mansell, 2001) that influences the onset and maintenance of various disorders and dysfunctions. Indeed, self-oriented perfectionism often acts as a vulnerability factor in unipolar depression and chronic depressive symptoms (Enns & Cox, 1999; Hewitt & Flett, 1993; Hewitt et al, 1996, 1998; Hewitt, Smith, Ge et al, 2022; Smith et al, 2016), anorexia nervosa (Bastiani et al, 1995) and early death (Fry & Debats, 2009). Similarly, other-oriented perfectionism is associated with significant personality, marital, sexual, and other relationship dysfunctions (e.g., Haring et al, 2003; Stoeber, 2014), while socially prescribed perfectionism is associated with suicide ideation, risk, and attempts in both child and adult samples (Flett et al, 2022; Hewitt et al, 2017; O’Connor, 2007; Smith et al, 2018).…”
