Summary
The Obsessive Compulsive Cocaine Scale (OCCS) effectively measures obsessive and compulsive cocaine use. This validated tool demonstrates strong reliability and predictive validity for individuals with cocaine dependence.
Area of Science:
- Psychiatry
- Psychology
- Addiction Medicine
Background:
- Cocaine dependence is a significant public health issue.
- Assessing obsessive and compulsive patterns of cocaine use is crucial for treatment.
- Existing measures may not fully capture the nuances of cocaine use behaviors.
Purpose of the Study:
- To evaluate the psychometric properties of the Obsessive Compulsive Cocaine Scale (OCCS).
- To adapt and validate a measure for obsessive and compulsive cocaine use.
- To assess the reliability and validity of the OCCS in a clinical population.
Main Methods:
- Administered the OCCS to 189 individuals with cocaine dependence in medication trials.
- Utilized confirmatory factor analysis to determine the factor structure.
- Assessed internal consistency, test-retest reliability, convergent validity, and predictive validity.
Main Results:
- Confirmatory factor analysis supported a two-factor structure: obsessions and compulsions.
- The OCCS demonstrated strong internal consistency and test-retest reliability.
- Evidence supported the convergent and predictive validity of the OCCS.
Conclusions:
- The OCCS is a psychometrically sound measure for assessing obsessive and compulsive cocaine use.
- The scale is reliable and valid for use in individuals with cocaine dependence.
- The OCCS can aid in understanding and treating cocaine use disorders.

01:28Obsessive-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...
01:22Self-Report Tests of Personality
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.
01:29Reliability and Validity
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.
01:29Five-Factor Theory of Personality
The five-factor model, often called the Big Five personality traits, is widely accepted in psychology as a comprehensive framework for understanding personality. These five traits — Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism — are often remembered using the acronym OCEAN.
Openness reflects creativity, curiosity, and openness to new experiences. Individuals scoring high in openness are imaginative, have a wide range of interests, and are independent thinkers. Low...

01:24Personality 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...

01:24Cattell's 16 Personality Factors
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 fundamental,...
