Dimensionality and homogeneity of the Colombian version of the Cocaine Craving Questionnaire (CCQ-N-10)

Background It is essential to have a validated instrument to measure craving for cocaine use. The study's objective was to understand the dimensionality and homogeneity of the Cocaine Craving Questionnaire (CCQ-N-10) among Colombian cocaine users. Methods A sample of 102 hospitalized or outpatient adults diagnosed with cocaine use disorders attending addiction units in Bucaramanga, Colombia. Internal consistency and construct validity were estimated by confirmatory factor analysis and correlation analysis with scales with similar objectives. Results An omega coefficient of 0.93 was obtained, and adjustment indicators of the confirmatory model were acceptable (RMSEA of 0.08, CFI and TLI of 0.99) when two of the original scale items were removed from the original scale analysis. Conclusion This study shows that the craving scale reduced to eight items can be helpful to assess the construct in the Colombian population; however, the small sample size makes it challenging to carry out other analysis to corroborate its psychometric properties.
