Nicotine replacement therapy (NRT) doubles the chances that a smoker will quit smoking, but most smokers who attempt to quit do not use it at all or only use it inconsistently. We aimed to identify attitudes of smokers and ex-smokers toward NRT and to develop and assess the validity of a brief scale used to measure these attitudes.
We conducted a first mail survey of 256 smokers and ex-smokers to collect qualitative data and to develop survey items and a second mail survey of 494 smokers and ex-smokers to finalize the scale and assess its validity. The study was conducted in Geneva, Switzerland, in 1998 to 1999.
The study resulted in a 2-dimensional, 12-item scale: the Attitudes Toward Nicotine Replacement Therapy scale (ANRT-12). The 2 subscales measure perception of the advantages of NRT (8 items) and the drawbacks of NRT (4 items). Internal consistency coefficients (alpha = 0.84 and 0.75, respectively) and test-retest correlations (0.79 for both scales) were high. The scales respected criteria of content and construct validity. Scores were associated with intention to use NRT, and among those who had ever used NRT, with the number of days of use. A disturbing result was that only 1 (16%) of 6 participants agreed that "NRT helps people quit smoking," and only 1 (24%) of 4 ex-smokers had ever used NRT.
Many smokers and ex-smokers have inadequate knowledge of and negative attitudes toward NRT. ANRT-12 is a valid and reliable measure of these attitudes; it can be used by clinicians, researchers, and educators to improve use of and compliance with NRT.
尼古丁替代疗法（NRT）使吸烟者戒烟的几率增加一倍，但大多数尝试戒烟的吸烟者根本不使用该疗法，或只是断断续续地使用。我们旨在确定吸烟者和已戒烟者对NRT的态度，并开发和评估一个用于测量这些态度的简短量表的有效性。
我们对256名吸烟者和已戒烟者进行了首次邮件调查，以收集定性数据并开发调查项目；对494名吸烟者和已戒烟者进行了第二次邮件调查，以确定量表并评估其有效性。该研究于1998年至1999年在瑞士日内瓦进行。
该研究得出了一个二维、12项的量表：尼古丁替代疗法态度量表（ANRT-12）。两个子量表分别测量对NRT优势的认知（8项）和对NRT劣势的认知（4项）。内部一致性系数（分别为α = 0.84和0.75）和重测相关性（两个量表均为0.79）都很高。这些量表符合内容和结构效度标准。得分与使用NRT的意愿相关，在曾经使用过NRT的人中，得分与使用天数相关。一个令人不安的结果是，6名参与者中只有1名（16%）同意“NRT有助于人们戒烟”，4名已戒烟者中只有1名（24%）曾经使用过NRT。
许多吸烟者和已戒烟者对NRT了解不足且持负面态度。ANRT-12是这些态度的有效且可靠的测量工具；临床医生、研究人员和教育工作者可使用它来提高NRT的使用和依从性。
