Summary
Simplified screening questions can effectively identify anger attacks, a common symptom in depression. Two specific questions accurately detect most patients experiencing these episodes, aiding diagnosis.
Area of Science:
- Psychiatry
- Clinical Psychology
Background:
- Anger attacks, characterized by sudden anger and autonomic arousal, are prevalent in depression.
- Current assessment relies on specific instruments, potentially limiting diagnosis.
Purpose of the Study:
- To validate a simplified definition for diagnosing anger attacks.
- To assess the utility of individual screening questions for anger attacks.
Main Methods:
- Validated the Anger Attacks Questionnaire in 203 major depression patients.
- Compared the first three items (irritability, overreaction, inappropriate anger/rage) against the diagnosis.
- Assessed the diagnostic value of single screening questions.
Main Results:
- Irritability showed weak association (kappa=0.214) and low specificity (0.302).
- Overreaction (kappa=0.869) and inappropriate anger/rage (kappa=0.901) demonstrated high agreement and specificity (0.918, 0.935).
- Combining the latter two questions achieved near-perfect reclassification (kappa=0.955, specificity=0.971).
Conclusions:
- Simplifying the diagnostic process for anger attacks is crucial due to likely underdiagnosis.
- One or two simple screening questions can identify most patients with anger attacks.
- This approach can improve the recognition of anger attacks in clinical settings.

01:47Aggression
Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for hire...
01:27Panic 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...
02:40The Scientific Method
Research is what makes the difference between facts and opinions. Facts are observable realities, and opinions are personal judgments, conclusions, or attitudes that may or may not be accurate. In the scientific community, facts can be established only using evidence collected through empirical research.
01:29Angina III: Clinical Manifestations and Assessment
Angina manifests as chest pain, tightness, or squeezing discomfort typically located behind the breastbone. It can radiate to the neck, jaw, shoulders, and inner aspects of the upper arms, most commonly the left arm. Patients may experience shortness of breath, fatigue, profuse sweating, dizziness, indigestion, heartburn, palpitations, anxiety, and vomiting as accompanying symptoms. This pain often lasts a few minutes and is triggered by physical exertion, emotional stress, heavy meals, or cold...
01:30Angina I: Introduction
Definition and Symptoms: Angina (angina pectoris) is chest pain or discomfort caused by myocardial ischemia, which occurs when the heart muscle receives insufficient oxygen-rich blood. It typically manifests as pressing, squeezing, or crushing sensations in the chest and may radiate to the shoulders, arms, neck, jaw, or back.Primary Cause: In a healthy state, the coronary arteries can dilate (widen) to increase blood flow and meet the increased oxygen demand during physical activity or...
01:30Oppositional Defiant Disorder
A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.
