Diagnostic and Statistical Manual of Mental Disorders (DSM)01:27

Diagnostic and Statistical Manual of Mental Disorders (DSM)

The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...
Post-traumatic Stress Disorder01:27

Post-traumatic Stress Disorder

Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events, are a...
Dissociative Identity Disorder01:30

Dissociative Identity Disorder

Dissociative Identity Disorder (DID), previously termed multiple personality disorder, is a complex psychological condition characterized by the presence of two or more distinct identities or personality states. Each identity exhibits unique patterns of behavior, voice, and mannerisms and may possess separate memories and emotional responses. The alternating control between identities can result in memory gaps and challenges in recalling daily activities, often exacerbating the individual's...
Anxiety: Overview01:18

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.
Individuals with anxiety often experience a range of physical and emotional symptoms, including sweating, trembling, tachycardia, and disturbances in sleep patterns. These symptoms vary in intensity and frequency but are generally disruptive and distressing.
Dissociative Disorders01:27

Dissociative Disorders

Dissociative disorders represent complex psychological conditions characterized by disruptions in consciousness, memory, identity, or perception. These disruptions cause individuals to experience a disconnection from their thoughts, emotions, and memories. The phenomenon is not merely an occasional lapse in attention but a profound alteration in mental functioning that can severely impact daily life.
Dissociative Fugue
A hallmark feature of dissociative disorders is the dissociative fugue...
Introduction to Psychological Disorders01:19

Introduction to Psychological Disorders

Abnormal behavior, often referred to as mental illness, results from changes in brain function that influence thought patterns, behaviors, and social interactions. Psychologists and psychiatrists typically assess abnormal behavior using three primary criteria: deviance, maladaptation, and personal distress, particularly when these traits persist over long periods.
Deviant Behavior
Deviance in behavior refers to actions or thought patterns that significantly diverge from societal norms or...

Area of Science:

  • Psychiatry
  • Clinical Psychology
  • Mental Health Diagnostics

Background:

  • The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) criteria for Posttraumatic Stress Disorder (PTSD) have been extensively reviewed.
  • Empirical literature primarily focuses on the DSM-IV-TR Criterion A (Stressor), specifically A1 (trauma criteria) and A2 (stressor-related distress/numbness).
  • Existing research questions the etiological relevance and temporal relationship of Criterion A1 and the utility of Criterion A2.

Purpose of the Study:

  • To review empirical literature on the DSM-IV-TR diagnostic criteria for PTSD.
  • To evaluate the necessity and utility of DSM-IV-TR Criteria A1 and A2 for PTSD diagnosis.
  • To propose revised diagnostic criteria for PTSD for the upcoming DSM-5, incorporating empirical findings and addressing limitations of the current system.

Main Methods:

  • Systematic review of empirical literature concerning the DSM-IV-TR diagnostic criteria for PTSD.
  • Analysis of research focusing on the stressor (Criterion A) and symptom clusters (Criteria B, C, and D).
  • Examination of confirmatory factor analyses to determine the latent structure of PTSD symptomology.

Main Results:

  • Empirical evidence provides little support for retaining the A2 criterion in DSM-5.
  • Confirmatory factor analyses suggest a four-cluster symptom structure for PTSD, differing from the DSM-IV's three-cluster model.
  • Traumatic exposure is associated with a broader range of symptoms than previously emphasized, including dysphoric, aggressive, dissociative, and negative appraisal symptoms.

Conclusions:

  • The A2 criterion for PTSD should be eliminated from DSM-5.
  • A revised DSM-5 PTSD diagnostic framework should incorporate four symptom clusters and expand beyond fear-based symptomology.
  • Further considerations for DSM-5 include partial PTSD, complex PTSD, and cross-cultural, developmental, and subtype variations.
