Summary
Functional Somatic Disorders (FSD) are linked to specific personality traits. Individuals with FSD show higher neuroticism and lower extraversion and agreeableness compared to healthy controls.
Area of Science:
- Psychiatry and Psychology
- Behavioral Science
Background:
- Functional Somatic Disorders (FSD) encompass conditions with persistent physical symptoms unexplained by other medical or psychiatric causes.
- Personality traits are hypothesized to play a role in FSD, but the exact relationship requires further investigation.
Purpose of the Study:
- To systematically review and meta-analyze the association between the Five-Factor Model (FFM) of personality traits and Functional Somatic Disorders (FSD).
Main Methods:
- Adherence to PRISMA guidelines for systematic review and meta-analysis.
- Searches conducted across PsycInfo, PubMed, and Embase databases.
- Inclusion of studies with FSD and control groups assessing FFM traits, analyzed using random effects models.
Main Results:
- FSD cases exhibited significantly higher neuroticism and lower extraversion and agreeableness compared to healthy/unspecified controls.
- Compared to somatic controls, FSD cases showed higher neuroticism and agreeableness, with no significant difference in extraversion.
- No significant associations were found for conscientiousness and openness; heterogeneity was noted, but no publication bias was detected.
Conclusions:
- The study confirms significant associations between Five-Factor Model personality traits and Functional Somatic Disorders.
- Findings offer valuable insights into the etiology, classification, and potential management strategies for FSD.

01:29Five-Factor Theory of Personality
794
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...

01:22Self-Report Tests of Personality
307
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

01:29Personality Theory by Eysenck and Eysenck
364
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,...

01:24Cattell's 16 Personality Factors
450
Raymond Cattell's trait theory offers a structured framework for understanding personality by distinguishing between two critical traits: surface and source traits. Surface traits are observable patterns of behavior, such as indecisiveness, anxiety, and irrational fears. These traits are less stable, varying across situations and over time. This means that they are less helpful in understanding the deeper aspects of an individual's personality.
In contrast, source traits are the...

Personality encompasses a set of enduring traits and behavioral patterns that define how individuals think, feel, and interact, ultimately shaping their unique identities. The concept of personality has deep historical roots, deriving from the Latin term "persona," which means "mask." This term initially referred to the roles played by actors in ancient theater, signifying the different facets individuals display in various contexts.

01:29Theoretical Approaches to Psychological Disorder
77
The development of psychological disorders, which are characterized by deviant, maladaptive, and personally distressing behaviors, has been explored through several theoretical approaches.
Biological approach
The biological approach posits that internal, organic factors are the primary causes of such disorders. This perspective emphasizes brain structure and function, genetic predispositions, and neurotransmitter imbalances. For example, schizophrenia has been associated with both genetic...
