Brief Description: The CDS-12 scale is a 12-item scale that assesses some components of formal diagnostic systems' (e.g., DSM-IV and ICD-10) definitions of dependence with an emphasis on compulsion to smoke, withdrawal, loss of control, time allocation, neglect of other activities, and persistence despite harm. This instrument does not measure tolerance. Items on self-perception of addiction and smoking rate are also included. Response choices are on a five-point Likert scale.

Clinical Utility of Instrument: The CDS-12 provides a continuous index of nicotine dependence (mixed with other smoking-relevant items), which can be useful in identifying eligible patients and in monitoring progress in cessation treatment.
Research Applicability: May be useful in identifying nicotine use/dependence severity in adolescents. Authors encourage direct comparison to other dependence measures in adolescence for further validation information.
