McNally2017 - Co-morbid obsessive-compulsive disorder and depression, a Bayesian network approach

Example citation

In a Bayesian network of OCD and depression, distress from obsessions acted as a bridge symptom between OCD and depression, activating sadness and subsequently the rest of the depressive cluster [@mcnally2017].

Key takeaways

  • Patients with primary OCD and depressive symptoms, n = 408
  • Y-BOCS-SR and Quick Inventory of Depressive Symptomatology (QIDS-SR)
  • Graphical LASSO algorithm and DAG using a Bayesian network approach
  • Interference & distress from obsessions, and interference from compulsions are most central in OCD
  • Distress from obsessions -> Sadness -> rest of depression cluster (bridge symptom) in DAG
