OCD Severity Analysis - EDA Summary

Part 1 — Main Research Question Goal: identify the strongest contributors to OCD severity.

Severity metric: YBOCS_Total = Obsessions Score + Compulsions Score

We tested whether severity is predicted by:

Family history of OCD -Depression / Anxiety diagnoses -Obsession type -Compulsion type -Duration of symptoms -Age / demographics -Medication type

Visual Results

External or demographic features do not explain OCD severity. The only strong correlation is between:

Obsessions intensity ↔ Compulsions intensity

Severity is not determined by what someone thinks, but by how strongly they reacts to the thought.

Part 2 - Sub-Analysis: Cognitive-Behavioral Reaction Profiles

To investigate the core finding, we created a behavioral metric: ReactionGap = Compulsions – Obsessions

Reaction Profiles: Resister (O > C) → strong intrusive thoughts, weak reaction Balanced (O ≈ C) → similar levels Reactive (C > O) → small intrusive thoughts, big compulsive reaction

Key Insight from Part 2:

Regardless of whether patients fight the thoughts (Resister), stay neutral (Balanced), or react strongly (Reactive), severity remains high when obsessions and compulsions move together.

Part 3 — Filtering Only the Low-Severity Group

To understand what protects certain patients, we isolated only:

SeverityGroup = "Low"

Key Insight from Part 3

Among patients with low OCD severity:

The most common pattern is having intrusive thoughts without escalating into compulsions.

In other words: Low-severity patients don’t stop the thoughts — they simply don’t react strongly to them.

Additional check:

Even patients with many years of OCD can remain low-severity — duration does not determine severity.

Final Takeaway

OCD severity is not driven by: Family history, Depression / Anxiety, Type of obsessions, Type of compulsions, Duration of symptoms, Medication

The single dominant driver is:

The intensity of the compulsive reaction to intrusive thoughts.

Clinical Interpretation

These findings support modern CBT / ERP / ACT approaches:

The goal is not to eliminate intrusive thoughts, but to reduce the behavioral reaction to them.
