To develop an approach for rapid assessment of tobacco control interventions in China. We examined the correlation between components of the Strength of Tobacco Control (SOTC) index and a proposed rapid evaluation indicator, the Policy Performance Indicator (PPI), which is based on protection of non-smokers from secondhand smoke (SHS). The PPI was used to assess the implementation of policies related to SHS at the provincial/municipal level in China.
Stratified random sampling was used to select five types of organisational and household respondents in two municipalities and five provinces in China (Shanghai and Tianjin, Heilongjiang, Henan, Guangdong, Zhejiang and Jiangxi, respectively). Data collection methods included key informant interviews, observation and intercept surveys (organisations), and a modified Global Adult Tobacco Survey (GATS) questionnaire (households). SOTC scores (SHS policy, capacity and efforts), PPI (no smoking in designated smoke-free places) and mid-term to long-term impact (knowledge, attitude and reduced exposure to SHS) were measured, and correlations among them were calculated.
The PPI varied across the seven locations. Shanghai led in the component indicators (at 56.5% for indoor workplaces and 49.1% for indoor public places, respectively), followed by Guangdong, Tianjin and Zhejiang (at 30-35% for these two indicators), and finally, Henan and Jiangxi (at 20-25%). Smoke-free policies were more effectively implemented at indoor workplaces than indoor public places. The PPI correlated well with certain components of the SOTC but not with the long-term indicators.
The PPI is useful for evaluating implementation of smoke-free policies. As tobacco control programmes are implemented, the PPI offers an indicator to track success and change strategies, without collecting data for a full SOTC index.
开发一种快速评估中国控烟干预措施的方法。我们检验了烟草控制力度（SOTC）指数各组成部分与基于保护非吸烟者免受二手烟（SHS）伤害的拟议快速评估指标“政策绩效指标（PPI）”之间的相关性。PPI 被用于评估中国省级/市级与 SHS 相关政策的实施情况。
采用分层随机抽样，在中国两个直辖市和五个省份（上海和天津，黑龙江、河南、广东、浙江和江西）选择五类组织和家庭受访者。数据收集方法包括对关键知情人进行访谈、观察和拦截调查（组织），以及对修正后的全球成人烟草调查（GATS）问卷（家庭）进行调查。测量了 SOTC 得分（SHS 政策、能力和努力）、PPI（指定无烟场所无烟）和中期到长期影响（知识、态度和减少 SHS 暴露），并计算了它们之间的相关性。
PPI 在七个地点之间存在差异。上海在两个指标（室内工作场所为 56.5%，室内公共场所为 49.1%）方面处于领先地位，其次是广东、天津和浙江（这两个指标为 30-35%），最后是河南和江西（这两个指标为 20-25%）。无烟政策在室内工作场所比在室内公共场所更有效地得到执行。PPI 与 SOTC 的某些组成部分密切相关，但与长期指标无关。
PPI 可用于评估无烟政策的实施情况。随着控烟计划的实施，PPI 提供了一个跟踪成功和改变策略的指标，而无需收集完整的 SOTC 指数数据。
