Stimulant Craving Questionnaire-Brief (STCQ-Brief; adapted from Sussner et al, 2006). The STCQ-Brief is a 10-item self-report measure derived from the 10-item Cocaine Craving Questionnaire-Brief and the original 46-item Cocaine Craving Questionnaire-Now (Tiffany et al, 1998). The STCQ-Brief assesses current craving for stimulants (cocaine, methamphetamine and other stimulants) using a seven-point scale, with answers ranging from “strongly disagree” to strongly agree”. The CCQ-Brief, from which the STCQ-Brief is adapted, has high internal consistency, with Cronbach’s alpha ranging from 0.87 (Paliwal et al, 2008) to 0.90 (Sussner et al, 2006). The instrument also has good construct validity and has shown to correlate well with other craving measures (Paliwal et al, 2008).
