Research Project: Psychological Network Models

Objective: The study (Zhang et al. 2024) examined sex-specific, symptom-level relationships among emotion regulation (ER), interpersonal problems (IP), and eating disorder (ED) psychopathology in a large sample of Chinese adolescents.

Summary:

  • The results revealed several significant nodes in the network structures for boys and girls.
    • Emotional awareness plays a bridging role for boys in the connection between ED and IP
    • weight/shape dissatisfaction plays the central rols for girls in eating disorder ecosystem
  • Findings indicate potential intervention targets (e.g. impulse-driven eating disorder psychopathology, supporting executive functioning in emotionally charged situations) of ED symptoms in adolescents.
