Summary
This study validated two cocaine craving questionnaires. Both versions demonstrated a consistent hierarchical factor structure, supporting their use in assessing cocaine craving in users.
Area of Science:
- Psychology
- Addiction Research
- Psychometrics
Background:
- Cocaine craving is a critical factor in addiction and relapse.
- Accurate measurement of cocaine craving is essential for research and clinical interventions.
- Existing instruments may not fully capture the multifaceted nature of craving.
Purpose of the Study:
- To develop and validate two versions of a questionnaire to measure cocaine craving.
- To examine the psychometric properties and factor structure of the cocaine craving instruments.
- To assess the reliability and validity of the 'Now' and 'General' craving measures.
Main Methods:
- Administered two 45-item cocaine craving questionnaires (Now and General versions) to 225 cocaine users.
- Conducted factor analyses to determine the underlying item structure for both questionnaire versions.
- Performed higher-order analyses to identify overarching factors and assessed scale reliabilities.
Main Results:
- Factor analyses revealed a consistent four-factor solution for both questionnaire versions.
- Higher-order analyses identified a single, pervasive second-order factor in each version.
- Derived factor scales demonstrated moderate to high reliability, and factors correlated across versions, suggesting a shared hierarchical structure.
Conclusions:
- Both the 'Now' and 'General' cocaine craving questionnaires exhibit a robust and consistent hierarchical factor structure.
- These validated instruments provide reliable measures for assessing current and recent average cocaine craving.
- The findings support the utility of these tools in both theoretical research and clinical practice for understanding and managing cocaine use disorder.
