Identifying the Symptom Severity in Obsessive-Compulsive Disorder for Classification and Prediction: An Artificial Neural Network Approach

الملخص EN

The present study is aimed at identifying the most prominent determinants of OCD along with their strength to classify the OCD patients from healthy controls.

The data for this cross-sectional study were collected from 200 diagnosed OCD patients and 400 healthy controls.

The respondents were selected through purposive sampling and interviewed by using the Y-BOCS scale with the addition of a factor, worth of an individual in his family.

The validity and reliability of data were assessed through Cronbach’s alpha and confirmatory factor analysis.

Artificial Neural Network (ANN) modeling was adopted to determine threatening determinants along with their strength to predict OCD in an individual.

The results of ANN modeling depicted 98% accurate classification of OCD patients from healthy controls.

The most contributing factors in determining the OCD patients according to normalized importance were the contamination and cleaning (100%); symmetric and perfection (72.5%); worth of an individual in the family (71.1%); aggressive, religious, and sexual obsession (50.5%); high-risk assessment (46.0%); and somatic obsessions and checking (24.0%).
