Using network analysis to personalize treatment for individuals with co-occurring restrictive eating disorders and...

Area of Science:

• Psychiatry
• Psychology
• Network Science

Background:

• Standard eating disorder interventions often lack specific guidance for managing suicidality.
• Anorexia Nervosa spectrum disorders (ANSD) frequently co-occur with suicidality, necessitating tailored treatment approaches.

Purpose of the Study:

• To demonstrate the utility of idiographic network models for personalizing treatment in ANSD with suicidality.
• To identify key symptoms and their relationships within individual patient networks.

Main Methods:

• Ecological momentary assessment data collected over 21 days for three ANSD patients.
• Generation of contemporaneous and temporal idiographic symptom networks.
• Identification of central and bridge symptoms within each patient's network.

Main Results:

• Network analysis revealed patient-specific central symptoms and bridge symptoms linking eating pathology and suicidality.
• Bridge symptoms emerged as promising targets for concurrent intervention.
• Targeting high centrality symptoms may lead to network-wide symptom improvement.

Conclusions:

• Idiographic network models can inform personalized treatment for co-occurring eating disorders and suicidality.
• Further research on intervention development is needed to fully realize the potential of this approach.
