Summary
This study found that specific personality traits, like conscientiousness and neuroticism, are linked to hoarding symptoms. Motivational factors also play a role, though personality traits are stronger predictors of hoarding behavior.
Area of Science:
- Psychology
- Behavioral Science
Background:
- Hoarding disorder is a complex condition with significant personal and societal impact.
- Understanding the underlying personality and motivational factors is crucial for effective intervention.
Purpose of the Study:
- To investigate the dispositional profile associated with hoarding symptoms.
- To examine the relationship between personality traits (aspect-level) and general causality orientations with hoarding.
- To provide a more nuanced understanding beyond broad personality factors.
Main Methods:
- A community sample (N=649, ages 18-74) with oversampled high hoarding symptoms completed online questionnaires.
- Assessed hoarding, the Five-Factor Model of personality (aspect-level traits), and general causality orientations from self-determination theory.
Main Results:
- Hoarding symptoms were correlated with higher neuroticism and conscientiousness.
- Specific personality aspects predicting hoarding included industriousness, orderliness, withdrawal, and assertiveness.
- Hoarding was related to impersonal and control orientations, with personality aspects being stronger predictors than motivational orientations.
Conclusions:
- Aspect-level personality traits and general causality orientations are associated with hoarding symptoms.
- Findings can inform preventative strategies and interventions for hoarding disorder.
- Highlights the importance of considering specific personality characteristics in hoarding clients.

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...

These perspectives incorporate behaviorist principles, such as learning through reinforcement and conditioning, but extend beyond them by highlighting human reasoning and planning. Unlike traditional behaviorist views, social cognitive theory focuses on how individuals reflect on their past experiences and plan for future outcomes by considering...

Implicit personality theory explains how individuals make assumptions about the relationships between personality traits, behaviors, and character types. When people learn that someone possesses a particular trait, they tend to infer the presence of other related characteristics, forming a cohesive impression. This cognitive shortcut plays a crucial role in social interactions and interpersonal judgments.Central Traits and Their InfluenceSolomon Asch's seminal 1946 study highlighted the power...

01:29Personality Theory by Eysenck and Eysenck
699
Hans and Sybil Eysenck developed a widely recognized theory of personality, which emphasizes the role of temperament and genetically based differences in shaping individual traits. Their theory posits that biological factors primarily determine personality and can be understood through two main dimensions: extroversion/introversion and neuroticism/stability.
In the extroversion/introversion dimension, highly extroverted people are sociable, outgoing, and easily connect with others. In contrast,...
