一天中第一支烟的时间（TTFC）是尼古丁依赖的一个新兴单项指标，因为它与身体依赖指数有很强的相关性。然而，尚不清楚这一衡量标准是否充分反映了依赖性的其他方面。依赖严重程度量表（SDS）是一种用于评估依赖心理方面的简短问卷，尚未广泛应用于吸烟研究。我们在戒烟试验的基线阶段检查了255名吸烟者的SDS和TTFC之间的关系。我们还研究了SDS和TTFC与生物行为依赖指数，戒烟行为和认知情感变量的相关性，并比较了这两种措施在预测这些变量方面的相对贡献。TTFC与SDS总分无关，但与SDS单项有关。TTFC，而不是SDS，与身体依赖指数相关（例如，CPD，CO）。TTFC和SDS都与戒烟行为相关，但关联方向相反。TTFC和SDS都与认知情感变量相关，但SDS在这些关系的强度和数量上优于TTFC。包括SDS和TTFC作为回归模型预测因子通常会增加解释的方差。研究结果表明，SDS和TTFC评估尼古丁依赖的不同结构;在吸烟者中，SDS似乎涉及依赖的非物理成分（例如，失去控制）与戒烟动机和影响有关。仅使用SDS评估尼古丁依赖可能无法捕获身体依赖性，而且可能无法反映SDS在其他药物滥用中评估的成瘾领域。尽管如此，除了TTFC之外，使用三个SDS项目可能比单独使用TTFC更有用。
The time to first cigarette (TTFC) of the day is an emerging single-item indicator of nicotine dependence due to its robust associations with indices of physical dependence. However, it is unclear if this measure adequately captures other dimensions of dependence. The Severity of Dependence Scale (SDS) is a brief questionnaire used to assess psychological aspects of dependence that has not yet been extensively applied to smoking research. We examined associations between the SDS and TTFC among 255 smokers during the baseline session of a cessation trial. We also examined associations of the SDS and TTFC with biobehavioral dependence indices, quitting behaviors, and cognitive-affective variables, and compared the relative contributions of both measures in predicting these variables. TTFC was unrelated to SDS total score, but was related to individual SDS items. TTFC, but not SDS, was correlated with indices of physical dependence (e.g., CPD, CO). Both TTFC and SDS were associated with quitting behaviors, with opposite directionality of associations. TTFC and SDS were both associated with cognitive-affective variables, but SDS outperformed TTFC in strength and number of these relationships. Including both the SDS and TTFC as regression model predictors often increased the amount of variance explained. Findings suggest that SDS and TTFC assess different constructs of nicotine dependence; among smokers, the SDS appears to tap into non-physical components of dependence (e.g., loss of control) that relate to quitting motivation and affect. Assessing nicotine dependence using only the SDS may fail to capture physical dependence and, further, may not reflect the same domains of addiction the SDS assesses in other drugs of abuse. Nonetheless, using three SDS items in addition to TTFC may offer utility over using TTFC alone.
