Anxiety: Overview

Anxiety is a common mental disorder featuring excessive worry, fear, and apprehension, significantly affecting daily life. People with anxiety disorders experience persistent and intense anxiety, interrupting their everyday functioning.

Social Anxiety Disorder

Social Anxiety Disorder

Social anxiety disorder, also known as social phobia, is characterized by an intense fear of social situations where one might face humiliation, rejection, embarrassment, or negative evaluation.

Self-Discrepancy and Its Effects

Self-Discrepancy and Its Effects

Self-discrepancy theory explains how people compare their actual self to their ideal and ought selves and how mismatches between these self-guides can lead to emotional distress. Developed by E. Tory Higgins, the theory distinguishes among three components of self-concept: the actual self, the ideal self, and the ought self. These refer respectively to how individuals perceive themselves, how they aspire to be, and how they believe they are obligated to be. Emotional well-being, self-esteem,...

Background:

Anxiety and fear are complex emotional states with significant public health implications.
Previous research has not fully delineated the core components of these emotions in diverse populations.

Purpose of the Study:

To identify and characterize the fundamental components of anxiety and fear within a large community sample.
To provide a nuanced understanding of the structure of anxiety and fear for clinical and research applications.

Main Methods:

Principal component analysis with promax rotation was employed to define subfactors.
Data were collected from 387 participants, including psychiatrically healthy and depressed individuals.
Correlations with psychiatric, physiological, and volumetric indicators were examined.

Main Results:

Five key components of anxiety and fear were identified: "discomfort," "fright," "nervousness," "lack of self-confidence," and "worry."
These components were analyzed based on organizational complexity and affective/motivational content.

Conclusions:

The identified components offer a structured framework for understanding anxiety and fear.
These components are derived from widely used psychiatric questionnaires, enhancing their utility for future research.
The findings contribute to a more precise assessment and study of emotional experiences.
