Obsessive-Compulsive Disorder01:28

Obsessive-Compulsive Disorder

815
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...

Personality Disorders: Dependent and Obsessive-Compulsive

613
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...

Oppositional Defiant Disorder

1.2K
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.

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...

Area of Science:

  • Psychiatry
  • Neuroscience
  • Clinical Psychology

Background:

  • The relationship between obsessive-compulsive symptoms (OCS) and different types of impulsivity and compulsivity requires clarification.
  • Understanding these links is crucial for psychiatric disorder classification and identifying traits across normal and clinical continua.

Purpose of the Study:

  • To investigate the associations between OCS and distinct forms of impulsivity and compulsivity in young adults.
  • To inform diagnostic conceptualizations and neurobiological models of OCS.

Main Methods:

  • 515 young adults (18-29 years) completed the Padua Inventory.
  • Participants underwent detailed clinical and neurocognitive assessments.
  • Linear regression modeling was used to analyze relationships between OCS, impulsivity, and compulsivity.

Main Results:

  • OCS were predicted by female gender, lower quality of life, general psychiatric disorders, and impaired extra-dimensional set-shifting.
  • Impulse control disorders, substance use, and specific neurocognitive measures (stop-signal reaction time, decision-making) did not significantly predict OCS.
  • Findings suggest OCS are more associated with compulsivity than impulsivity.

Conclusions:

  • Obsessive-compulsive symptoms are more closely related to specific forms of compulsivity than impulsivity.
  • These results have significant implications for psychiatric diagnostic frameworks and understanding the neurobiology of OCS.
