Background: The craving is a very important factor in the treatment of drug addiction. Objective: Validate the Cocaine Craving Questionnaire-Brief - Brazilian Crack Adapted Version. Method: Subjects enrolled in this experimental study were randomized into groups: experimental for this group was shown an image of a subject using crack (G1) and control (G2) for this group no pictures were shown. The sample was composed of 109 subjects (G1 = 50 and G2 = 59), males, crack/cocaine dependent inpatients. The assessment instruments were: Clinical Interview with social and demographic data, CCQ-B - Crack Adapted Version; Visual Analogic Scale for Craving, Anxiety and Depression Beck and Inventories Visual Cue to elicit craving. Results: On the factorial analysis two factors were found: Factor 1, related to craving itself, and Factor 2, the perceived lack of control of crack use. The two-factor factorial analysis presented a total variation of 68.84%, and the correlation between these factors was significant and of low intensity (r = 0.204; p = 0.041). A Cronbach’s alpha value from total of points of scale was 0.85. We observed a correlation between the scale total score and the Visual Analogic Scale (r = 0.515; p < 0.01). Conclusion: The Cocaine Craving Questionnaire-Brief - Brazilian Crack Adapted Version proved to be an adequate psychometric instrument for use in research and in clinical settings.
