Shabuj Chaya is a weekly television drama broadcast during a 13-week period in Bangladesh in 2000. It used an entertainment-education format to increase health knowledge and to promote visits to health clinic and modern contraceptive use. The purpose of this article is to demonstrate how a relatively new statistical technique, propensity score matching in conjunction with structural equation modeling, can be used to obtain an unbiased estimate of changes in health outcomes that can be attributed to exposure to the drama. The analysis is conducted with data from an after-only, cross-sectional survey of 4,492 men and women from the intended audience. The results from propensity score matching approximate what would be expected from a randomized control group design.
《沙布杰·查亚》是一部每周播出的电视剧，于2000年在孟加拉国为期13周的时间段内播出。它采用了娱乐教育的形式来增加健康知识，并促进人们前往健康诊所就诊以及使用现代避孕方法。本文的目的是展示一种相对较新的统计技术——倾向得分匹配结合结构方程模型，如何能够用于获得可归因于接触该剧的健康结果变化的无偏估计。该分析使用了来自对目标受众的4492名男性和女性进行的仅事后横断面调查的数据。倾向得分匹配的结果近似于随机对照组设计所预期的结果。
