Reliability and validity of the Spanish adaptation of the brief form of the Cocaine Craving Questionnaire-Now (CCQ-N-10)
Objective: To assess the metric properties of the abridged, 10-item version of the Cocaine Craving Questionnaire-Now (CCQ-N-10) in its Spanish adaptation. Method: The sample consists of 63 people beginning treatment for cocaine-abuse (n=23) or dependence (n=40) disorders according to DSM-IV criteria...

| Summary: | Objective: To assess the metric properties of the abridged, 10-item version of the Cocaine Craving Questionnaire-Now (CCQ-N-10) in its Spanish adaptation. Method: The sample consists of 63 people beginning treatment for cocaine-abuse (n=23) or dependence (n=40) disorders according to DSM-IV criteria. Participants completed an assessment battery that included the extended, 45-item version of the Cocaine Craving Questionnaire (CCQ-N-45) -in which the CCQ-N-10 is embedded-, the Cocaine Craving Scale (CCS), a Visual Analog Craving Scale (VAS), the Severity of Dependence Scale (SDS). and the Clinical Psychiatric Impression (CPI). Results: Cronbach's values for the CCQ-N-10, CCQ-N-45, SIDS and CCS scales were 0.95, 0.88, 0.79 and 0.93, respectively, indicating that all instruments show high internal consistency. Test-retest reliability for the CCQ-N-10 was fair (Intraclass Correlation Coefficient=0.59; p < 0.001). A factor analysis of the CCQ-N-10 (KMO=0.85) shows a one-factor structure explaining 68.6% of the variance, with factor loadings ranging from 0.64 to 0.92. Confirmatory factor analysis supports the unidimensionality of the scale (CF = 0.91; SRMR=0.06). The CCQ-N-10 explains 86.6% of the variance accounted for by the CCQ-N extended version (CCQ-N-45) and shows convergent validity with related measures such as the CCS (r=0.64, p < 0.001), VAS (r=0.65, p < 0.001), SDS (r=0.53, p < 0.001) and CPI (r=0.50, p < 0.001). Persons fulfilling criteria for cocaine-dependence disorder, compared to those who present cocaine abuse, show higher CCQ-N-10 scores (F-(1;60.6)=7.16, p=0.010). Conclusions: The Spanish adaptation of the CCQ-N-10 shows metric adequacy, and can be considered as a suitable assessment instrument in relation to cocaine-use disorders. |
