Valid and reliable brief measures of cigarette dependence are essential for research purposes and effective clinical care. Two widely-used brief measures of cigarette dependence are the six-item Fagerström Test for Cigarette Dependence (FTCD) and five-item Cigarette Dependence Scale (CDS-5). Their respective metric characteristics among pregnant smokers have not yet been studied.
This was a secondary analysis of data of pregnant smokers (N = 476) enrolled in a smoking cessation study. We assessed internal consistency, reliability, and examined correlations between the instruments and smoking-related behaviors for construct validity. We evaluated predictive validity by testing how well the measures predict abstinence 2 weeks after quit date.
Cronbach's alpha coefficient for the CDS-5 was 0.62 and for the FTCD 0.55. Measures were strongly correlated with each other, although FTCD, but not CDS-5, was associated with saliva cotinine concentration. The FTCD, CDS-5, craving to smoke, and withdrawal symptoms failed to predict smoking status 2 weeks following the quit date.
Suboptimal reliability estimates and failure to predict short-term smoking call into question the value of including either of the brief measures in studies that aim to explain the obstacles to smoking cessation during pregnancy.
有效且可靠的简短吸烟依赖测量方法对于研究目的和有效的临床护理至关重要。两种广泛使用的简短吸烟依赖测量方法是六项的尼古丁依赖Fagerström测试（FTCD）和五项的吸烟依赖量表（CDS-5）。尚未对孕妇吸烟者中它们各自的度量特征进行研究。
这是对参与戒烟研究的孕妇吸烟者（N = 476）数据的二次分析。我们评估了内部一致性、可靠性，并检查了这些工具与吸烟相关行为之间的相关性以验证结构效度。我们通过测试这些测量方法对戒烟日期后2周的戒烟情况预测得如何来评估预测效度。
CDS-5的Cronbach's alpha系数为0.62，FTCD的为0.55。尽管FTCD（而非CDS-5）与唾液可替宁浓度相关，但这些测量方法彼此之间相关性很强。FTCD、CDS-5、吸烟渴望和戒断症状未能预测戒烟日期后2周的吸烟状况。
可靠性估计欠佳以及未能预测短期吸烟情况，使得在旨在解释孕期戒烟障碍的研究中纳入这两种简短测量方法中的任何一种的价值受到质疑。
