  • Bridging of childhood obsessive-compulsive personality disorder traits and adult eating disorder symptoms: A network analysis approach
    by Sarah Giles on January 22, 2022

    OBJECTIVES: Obsessive-compulsive personality disorder (OCDP) traits are commonly associated with eating disorders (EDs), with evidence demonstrating that these traits predispose and exacerbate the ED illness course. However, limited research has examined the symptomatic interplay between ED and OCDP traits. We used network analysis to (1) identify the most central symptoms in a network comprised of OCPD traits retrospectively assessed in childhood and ED symptoms and (2) to identify symptoms...

An alternative interpretation is that set shifting is predictive of large weight changes and eating behaviors...
