Panic Disorder

Panic Disorder

Panic disorder is an anxiety disorder characterized by recurrent and sudden minutes-long episodes of intense fear, known as panic attacks. These attacks may feel like heart attacks and often happen without warning or a specific cause. They can include symptoms such as rapid heart rate, shortness of breath, chest pain, trembling, sweating, dizziness, and a sense of helplessness. During a panic attack, individuals may feel as though they are experiencing a heart attack or are in a...

Factorial Design

Factorial Design

Factorial Analysis is an experimental design that applies Analysis of Variance (ANOVA) statistical procedures to examine a change in a dependent variable due to more than one independent variable, also known as factors. Changes in worker productivity can be reasoned, for example, to be influenced by salary and other conditions, such as skill level. One way to test this hypothesis is by categorizing salary into three levels (low, moderate, and high) and skills sets into two levels (entry level...

Generalized Anxiety Disorder

Generalized Anxiety Disorder

Generalized Anxiety Disorder (GAD) is a chronic condition characterized by excessive and uncontrollable worry that persists for at least six months, significantly interfering with daily functioning. Unlike situational anxiety, which arises in response to specific stressors, GAD often occurs without a clear cause. Individuals may experience disproportionate worry about work, health, or relationships. For instance, a person might continuously fear poor health despite normal medical evaluations or...

Factors Affecting Illness

Factors Affecting Illness

When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness, disability,...

Cattell's 16 Personality Factors

Cattell's 16 Personality Factors

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 fundamental,...

Area of Science:

Psychiatry
Clinical Psychology

Background:

Panic disorder is a significant mental health condition.
Previous research has explored panic symptom classifications.

Purpose of the Study:

To identify distinct clinical subtypes of panic disorder.
To analyze panic symptoms using factor analysis.

Main Methods:

Principal component analysis with varimax rotation was applied.
13 Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) panic symptoms were analyzed in 94 subjects.

Main Results:

Four clinically meaningful factors emerged: autonomic hyperactivity (Factor I), cognitive symptoms (Factor II), mixed somatic/anxiety symptoms (Factor III), and respiratory symptoms (Factor IV).
These factors represent distinct patterns of panic symptom presentation.

Conclusions:

The findings support the existence of clinically meaningful subtypes of panic disorder.
These subtypes have implications for understanding and potentially treating panic disorder.
