吸烟在低收入人士和某些少数种族/族裔中更为普遍。解决不同人群的戒烟问题是一项紧迫的公共卫生优先事项。随着互联网在美国各阶层人口中的使用继续增加，基于网络的干预措施具有巨大的潜力，可以覆盖重点人群。在重点人群中进行基于网络的戒烟研究需要心理测量学上健全的测量工具。到目前为止，只有一个已发表的研究已经审查了心理测量特性的互联网管理的措施，通常用于基于Web的戒烟试验。然而，样本在种族/族裔和收入方面是同质的。我们试图在更多样化的吸烟者样本中复制和扩展这些发现。 目的是检查在少数种族/族裔和低收入吸烟者中进行戒烟临床试验时常用的测量方法的内部一致性和重测信度。 参与者在2005年6月至2006年9月期间参加了一项关于互联网戒烟计划有效性的随机试验。在基线电话评估和随机分配至母试验后，招募受试者参加可靠性子研究。在招募阶段I，母试验的所有受试者均被招募至子研究;在招募阶段II，母试验的所有连续种族/少数民族受试者均被招募。通过自我报告使用美国管理和预算办公室的两个标准项目对种族和民族进行评估。电话评估后2天发送了一封电子邮件，其中包含互联网调查的链接。检查的措施戒烟方法，感知压力，抑郁，社会支持，吸烟诱惑，饮酒，感知健康状况和收入。互联网与电话管理的措施的内部一致性和重测信度进行了检查，在四个分层定义的种族/民族（非西班牙裔白色，种族/少数民族）和家庭年收入（40,000美元或更少，超过40,000美元）。 在受邀的442人中，有319人参与（响应率为72%）：52.4%为非西班牙裔白色人，22.9%为黑人，11.6%为西班牙裔，7.8%为亚洲人，4.4%为美洲印第安人/阿拉斯加原住民，1%为夏威夷原住民/其他太平洋岛民。大约一半（49.4%）的家庭年收入为4万美元或以下，25.7%的人具有高中或以下学历。重测信度在所有阶层中均为满意到优秀：12个连续变量中有9个的组内相关系数≥ 0.70，18个二元变量和两个有序变量中有10个的Kappa系数≥ 0.70。几种戒烟方法的重测信度在不同阶层中存在差异。 种族/民族和收入不影响大多数互联网管理的措施检查的心理特性。这些知识增加了进行基于网络的戒烟研究的信心，并加强了通过互联网收集少数种族/民族和低收入亚群体信息的科学严谨性。clinicaltrials.gov NCT 00282009（母公司试验）
Smoking is more prevalent among lower-income individuals and certain racial/ethnic minorities. Addressing tobacco cessation among diverse populations is an urgent public health priority. As Internet use continues to rise among all segments of the US population, Web-based interventions have enormous potential to reach priority populations. Conducting Web-based smoking cessation research in priority populations requires psychometrically sound measurement instruments. To date, only one published study has examined the psychometric properties of Internet-administered measures commonly used in Web-based cessation trials. However, the sample was homogeneous with regard to race/ethnicity and income. We sought to replicate and extend these findings in a more diverse sample of smokers. The aim was to examine the internal consistency and test-retest reliability of measures commonly used in smoking cessation clinical trials among racial/ethnic minorities and smokers with lower income. Participants were enrolled in a randomized trial of the efficacy of an Internet smoking cessation program between June 2005 and September 2006. Following a baseline telephone assessment and randomization into the parent trial, participants were recruited to the reliability substudy. In phase I of recruitment, all participants in the parent trial were recruited to the substudy; in phase II, all consecutive racial/ethnic minority participants in the parent trial were recruited. Race and ethnicity were assessed via self-report using two standard items from the US Office of Management and Budget. An email was sent 2 days after the telephone assessment with a link to the Internet survey. Measures examined were quit methods, perceived stress, depression, social support, smoking temptations, alcohol use, perceived health status, and income. Internal consistency and test-retest reliability of Internet- versus telephone-administered measures were examined within four strata defined by race/ethnicity (non-Hispanic White, racial/ethnic minority) and annual household income (US $40,000 or less, more than $40,000). Of the 442 individuals invited, 319 participated (72% response rate): 52.4% were non-Hispanic White, 22.9% Black, 11.6% Hispanic, 7.8% Asian, 4.4% American Indian / Alaska Native, and 1% Native Hawaiian / Other Pacific Islander. About half (49.4%) reported an annual household income of US $40,000 or less, and 25.7% had a high school degree or less. Test-retest reliability was satisfactory to excellent across all strata for the majority of measures examined: 9 of 12 continuous variables had intraclass correlation coefficients ≥ 0.70, and 10 of 18 binary variables and both ordinal variables had kappa coefficients ≥ 0.70. Test-retest reliability of several quit methods varied across strata. Race/ethnicity and income do not affect the psychometric properties of most Internet-administered measures examined. This knowledge adds to the confidence of conducting Web-based smoking cessation research and strengthens the scientific rigor of collecting information via the Internet on racial/ethnic minority and low-income subgroups. clinicaltrials.gov NCT00282009 (parent trial)
