Obsessive-Compulsive Disorder01:28

Obsessive-Compulsive Disorder

180
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...

Self-Report Tests of Personality01:22

Self-Report Tests of Personality

415
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Personality Disorders: Dependent and Obsessive-Compulsive

118
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...

Cattell's 16 Personality Factors01:24

Cattell's 16 Personality Factors

1.1K
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...

Area of Science:

  • Psychiatry
  • Psychology
  • Behavioral Science

Background:

  • Compulsivity is a transdiagnostic construct relevant to psychiatric disorders.
  • Existing measures for compulsivity lack large-scale validation.
  • Understanding compulsivity's structure is crucial for clinical and nonclinical research.

Purpose of the Study:

  • To characterize the multidimensional latent structure of self-reported compulsivity.
  • To validate the Cambridge-Chicago Compulsivity Trait Scale (CHI-T) in a large population sample.
  • To provide normative data for the CHI-T scale.

Main Methods:

  • Utilized exploratory structural equation modeling (ESEM).
  • Analyzed data from a large population-based sample of British children and adults (N = 182,145).
  • Assessed discriminant validity against the Big Five personality dimensions.

Main Results:

  • Identified a correlated two-factor model of compulsivity: Perfectionism and Reward Drive.
  • Demonstrated discriminant validity of the CHI-T scale.
  • Confirmed acceptable test-retest reliability for the CHI-T scale.

Conclusions:

  • The CHI-T scale, validated at large scale, is a reliable measure of compulsivity.
  • The identified dimensions (Perfectionism, Reward Drive) offer insight into compulsivity's structure.
  • Normative data will aid future research on compulsivity's correlates and basis.
