Chunk #33 — Suggested Criteria for the Assessment of Tobacco Dependence — Rationale for Included Criteria — Criteria 3 & 4: Time to first cigarette (TTFC) after waking, and usual number of cigarettes consumed per day (cpd)
A recent analysis tested whether adding a cigarette quantity-frequency item reflecting daily smoking rate, increased model fit when added to the set of DSM-IV criteria [109]. The results suggested that a CPD item actually decreased model fit. This suggests that adding a single item to the existing DSM criteria is probably not a good strategy for improving the DSM (although see [32]); greater changes to the DSM criteria are needed.
