治疗效果的定量研究可能会形成许多配对的治疗受试者和未治疗的对照，他们在治疗前测量的协变量方面看起来相似。当治疗不是随机分配时，一个不可避免的问题是，在测量的协变量中看起来相似的个体在未测量的协变量中可能不相似。另一个令人关切的问题是，在缺乏定量数据中没有记录的背景的情况下，定量措施可能会被调查人员误解。当文本信息被自动编码以形成定量测量时，对叙事上下文的检查可以揭示初始编码努力的局限性。现有的一个建议需要对匹配对的子集进行叙述性描述，希望在一个子集中观察到更多没有定量测量或自动编码的东西。一个配对的子集不能排除对许多配对的分析产生实质性影响的微妙偏差，但也许一个配对的子集可以为此类偏差的讨论提供信息，也许会导致对定量数据的重新解释，或者提出新的考虑和观点。大量关于定性研究的文献认为，对一部分人的开放式叙述性描述可以提供信息。在这里，我们讨论并应用一种形式的最佳匹配，支持这样一个综合的，定量加定性的研究。最佳匹配提供了许多密切匹配的对加上一个子集的非常密切的对适合叙事解释。我们说明了匹配技术使用的数据，从最近的一项研究中的警察对家庭暴力的反应在费城，警方的报告包括定量和叙述性的信息。
Abstract A quantitative study of treatment effects may form many matched pairs of a treated subject and an untreated control who look similar in terms of covariates measured prior to treatment. When treatments are not randomly assigned, one inevitable concern is that individuals who look similar in measured covariates may be dissimilar in unmeasured covariates. Another concern is that quantitative measures may be misinterpreted by investigators in the absence of context that is not recorded in quantitative data. When text information is automatically coded to form quantitative measures, examination of the narrative context can reveal the limitations of initial coding efforts. An existing proposal entails a narrative description of a subset of matched pairs, hoping in a subset of pairs to observe quite a bit more of what was not quantitatively measured or automatically encoded. A subset of pairs cannot rule out subtle biases that materially affect analyses of many pairs, but perhaps a subset of pairs can inform discussion of such biases, perhaps leading to a reinterpretation of quantitative data, or perhaps raising new considerations and perspectives. The large literature on qualitative research contends that open-ended, narrative descriptions of a subset of people can be informative. Here, we discuss and apply a form of optimal matching that supports such an integrated, quantitative-plus-qualitative study. The optimal match provides many closely matched pairs plus a subset of exceptionally close pairs suitable for narrative interpretation. We illustrate the matching technique using data from a recent study of police responses to domestic violence in Philadelphia, where the police report includes both quantitative and narrative information.
