Oppositional Defiant Disorder01:30

Oppositional 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.

Obsessive-Compulsive Disorder01:28

Obsessive-Compulsive Disorder

Obsessive-compulsive disorder (OCD) is a mental health condition characterized by recurrent obsessions, compulsions, or both, which consume significant time and interfere with daily functioning. Obsessions involve persistent, intrusive, and unwanted thoughts, images, or urges that evoke anxiety. Common examples include irrational fears of contamination or harm. Compulsions are repetitive behaviors or mental acts performed to reduce the anxiety caused by obsessions. For instance, individuals...
Conduct Disorder01:28

Conduct Disorder

Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...
Personality Disorders: Dependent and Obsessive-Compulsive01:24

Personality Disorders: Dependent and Obsessive-Compulsive

Dependent personality disorder and obsessive-compulsive personality disorder are two separate psychological conditions that influence behavior, relationships, and overall life functioning. Though both involve maladaptive behaviors, their core characteristics and motivations differ significantly.
 Dependent Personality Disorder
Dependent personality disorder is characterized by an excessive reliance on others to manage various aspects of life. Individuals with this disorder often struggle with...
Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.
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...

Summary

The modified Children's Yale-Brown Obsessive Compulsive Scales (CYBOCS-PDD) is a reliable tool for assessing obsessive-compulsive symptoms in children with pervasive developmental disorders (PDDs). It effectively measures symptom severity and is sensitive to changes over time.

Area of Science:

  • Pediatric psychopharmacology
  • Child and adolescent psychiatry
  • Neurodevelopmental disorders

Background:

  • Pervasive developmental disorders (PDDs) are associated with obsessive-compulsive symptoms.
  • Accurate assessment of these symptoms is crucial for effective treatment.
  • Existing scales may require modification for this population.

Purpose of the Study:

  • To evaluate the psychometric properties of a modified Children's Yale-Brown Obsessive Compulsive Scales (CYBOCS-PDD).
  • To assess the reliability and validity of the CYBOCS-PDD in children with PDDs.

Main Methods:

  • A modified five-item CYBOCS (CYBOCS-PDD) was administered to 172 children with PDDs.
  • Raters were trained to reliability across five research units.
  • Reliability was assessed using intraclass correlation coefficient (ICC) and internal consistency with Cronbach's alpha.

Main Results:

  • The CYBOCS-PDD demonstrated excellent inter-rater reliability (ICC = 0.97) and internal consistency (alpha = .85).
  • Scores correlated similarly with measures of repetitive behavior, irritability, and hyperactivity.
  • Higher CYBOCS-PDD scores were linked to increased maladaptive behaviors and decreased adaptive functioning.

Conclusions:

  • The five-item CYBOCS-PDD is a reliable and valid measure for assessing obsessive-compulsive symptoms in children with PDDs.
  • The scale is distinct from other repetitive behavior measures and sensitive to clinical changes.
