“…Similar developmental models have been proposed in relation to anxiety (Bifulco et al 2006;Warren, Huston, Egeland, & Sroufe, 1997), depression (Bifulco et al, 2006;Fowler, Allen, Oldham, & Frueh, 2013), bipolar disorder (Morriss, van der Gucht, Lancaster, & Bentall, 2009), posttraumatic stress disorder (Ortigo, Westen, Defife, & Bradley, 2013) and personality disorders (Ma, 2006), particularly the borderline (Choi-Kain, Fitzmaurice, Zarnarini, Laverdiere, & Gunderson, 2009;Fongay & Luyten, 2009) and avoidant (Eikenaes, Pedersen, & Wilberg, 2016;Hageman, Francis, Field, & Carr, 2015) types. Furthermore, the utility of attachment theory is demonstrated by a recent meta-analysis of 36 studies involving a total of 3,158 patients with a range of Axis I and Axis II diagnoses: Significantly better outcomes were observed for those with secure (as against insecure) attachment styles, on data collected across various psychotherapeutic orientations (Levy, Kivity, Johnson, & Gooch, 2018).…”
