Five-Factor Theory of Personality

Five-Factor Theory of Personality

The five-factor model, often called the Big Five personality traits, is widely accepted in psychology as a comprehensive framework for understanding personality. These five traits — Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism — are often remembered using the acronym OCEAN.
Openness reflects creativity, curiosity, and openness to new experiences. Individuals scoring high in openness are imaginative, have a wide range of interests, and are independent thinkers. Low...

Summary

This summary is machine-generated.

Obsessive-compulsive personality disorder (OCPD) is a maladaptive variant of conscientiousness. This study found that measures of maladaptive conscientiousness strongly correlated with OCPD symptoms, supporting the dimensional perspective.

Area of Science:

Psychology
Psychopathology
Personality Science

Background:

A dimensional perspective suggests personality disorders are extreme variants of normal traits.
Obsessive-compulsive personality disorder (OCPD) has inconsistent empirical support within this dimensional framework.

Purpose of the Study:

To investigate if OCPD represents a maladaptive variant of conscientiousness.
To examine the relationship between conscientiousness traits and OCPD components.

Main Methods:

Administered multiple measures of conscientiousness, DSM-IV OCPD, and OCPD components to 536 undergraduates.
Oversampled participants with elevated OCPD scores.

Main Results:

Six conscientiousness measures showed strong convergence, indicating assessment of a common trait.
Conscientiousness measures correlated highly with specific OCPD components.
Measures of maladaptive conscientiousness demonstrated larger effect sizes with OCPD than general conscientiousness measures.

Conclusions:

Findings support OCPD as a maladaptive variant of normal-range conscientiousness.
The dimensional model is strengthened for OCPD when focusing on maladaptive trait expressions.
