Chunk #28 — 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)
These criteria are based on FTND items (items 1 & 4). There is evidence that the FTND and DSM assessments tap somewhat distinct domains; e.g., the correlation between the two is fairly modest. For instance, in one study the correlation between the FTND and a paper-pencil version of the DSM-IV was only .26 [90]. Similarly the FTND was correlated with DSM-IV diagnosis determined via structured interview at only r’s = .24 – .35 [91]. Thus, there is only a modest level of shared variance between the two measures and they diagnose somewhat different groups of people as dependent [92] also see [28, 91, 93, 94].
