社交网络在吸烟中起着重要作用。在戒烟期间提供社会支持是治疗的基石。戒烟的在线社交网络无处不在，是吸烟者接受和提供戒烟所需支持的一种有前途的方式。目前还没有专门针对网上戒烟社会支持的措施。其目的是开发一种用于在线戒烟治疗研究的社会支持措施。吸烟者在线社会支持量表（OS4）的初始项目是基于现有的理论和各种分类中描述的量表。初步的现场分析（N = 73）进行了23个初始项目，以优化规模。在一项关于互联网和电话戒烟治疗的大型随机试验的背景下，在3、6、12和18个月随访的情况下，对15项量表进行了进一步开发。总共有1326名参与者被随机分配到包括大型在线社交网络的增强型互联网组;心理测量学分析采用了至少一次报告使用增强型互联网干预的患者的3个月随访数据（n = 873）。项目进行了因素分析，内部一致性信度的量表进行了检查沿着与结构和效标效度。研究中使用的其他指标包括人口统计学、尼古丁依赖、伴侣对戒烟的支持、一般社会支持、社会融合、压力、抑郁、健康状况、在线社区使用、互联网使用行为、干预满意度和30天时点戒烟率。最终的12项OS4量表在人口统计学和吸烟分层中表现出较高的内部一致性可靠性（Cronbach α.86-.89）。OS4也表现出良好的结构和标准效度，与观察到的关联的方向性提供支持的先验假设。在OS4和伴侣互动问卷（PIQ）阳性分量表之间观察到显著的Pearson相关性（ρ = 0.24，P <0.001）。正如假设的那样，具有最高OS 4分数的参与者更有可能积极参与增强的互联网社区，并且对增强的互联网干预具有较高的满意度。在逻辑回归分析中，OS 4对6个月、12个月和18个月时的30天点患病率禁欲具有高度预测性（所有P值均<.001）。在线社会支持每增加一个标准单位，6个月时禁欲的几率增加48%（95%置信区间[CI] 1.17 - 1.71），12和18个月时仅略微下降至37%（95% CI 1.17 - 1.59）。OS4是一个简单，可靠，有效的工具，用于测量戒烟的在线社会支持。结果应该被复制和扩展，但这项研究表明，OS 4可用于推进理论，理解机制，并可能有助于改善基于互联网的戒烟治疗的定制。它还可以启发为其他在线健康相关干预研究制定类似措施。Clinicaltrials.gov
Social networks play an important role in smoking. Provision of social support during cessation is a cornerstone of treatment. Online social networks for cessation are ubiquitous and represent a promising modality for smokers to receive and provide the support necessary for cessation. There are no existing measures specific to online social support for smoking cessation. The objective was to develop a measure of social support to be used in online smoking cessation treatment research. Initial items for the Online Social Support for Smokers Scale (OS4) were based on existing theory and scales delineated in various taxonomies. Preliminary field analysis (N = 73) was conducted on 23 initial items to optimize the scale. Further development was conducted on a refined 15-item scale in the context of a large randomized trial of Internet and telephone cessation treatment with follow-ups at 3, 6, 12, and 18 months. In all, 1326 participants were randomized to an enhanced Internet arm that included a large online social network; psychometric analyses employed 3-month follow-up data from those reporting use of the enhanced Internet intervention at least once (n = 873). Items were subjected to a factor analysis, and the internal consistency reliability of the scale was examined along with construct and criterion validity. Other measures used in the study included demographics, nicotine dependence, partner support for cessation, general social support, social integration, stress, depression, health status, online community use, Internet use behaviors, intervention satisfaction, and 30-day point prevalence abstinence. The final 12-item OS4 scale demonstrated high internal consistency reliability (Cronbach alphas .86-.89) across demographic and smoking strata of interest. The OS4 also demonstrated good construct and criterion validity, with the directionality of the observed associations providing support for most a priori hypotheses. Significant Pearson correlations were observed between the OS4 and the Partner Interaction Questionnaire (PIQ) Positive subscale (ρ = .24, P < .001). As hypothesized, participants with the highest OS4 scores were more likely to have actively participated in the enhanced Internet community and to have high levels of satisfaction with the enhanced Internet intervention. In logistic regression analyses, the OS4 was highly predictive of 30-day point-prevalence abstinence at 6, 12, and 18 months (all P values <.001). The odds of abstinence at 6 months rose by 48% for each standard unit increase in online social support (95% confidence interval [CI] 1.17 - 1.71), dropping only slightly to 37% at 12 and 18 months (95% CI 1.17 - 1.59). The OS4 is a brief, reliable, and valid instrument for measuring online social support for smoking cessation. Results should be replicated and extended, but this study suggests the OS4 can be used to advance theory, understand mechanisms, and potentially help to improve the tailoring of Internet-based smoking cessation treatments. It can also inspire development of similar measures for other online health-related intervention research.
