Tóm tắt	Open-ended political response coding is the systematic content analysis of verbatim survey answers, classically the American National Election Studies likes/dislikes about parties and candidates, into a categorical scheme so they can be analyzed quantitatively. It applies content-analysis methodology (Krippendorff, 2004) to capture the substance and sophistication of citizens' political thinking that closed-ended items cannot.	The Political Knowledge Scale measures the range of factual information about politics that citizens hold and can retrieve, operationalized as a battery of factual quiz items. Delli Carpini and Keeter (1993, 1996) established the canonical short batteries (often five items) and argued that general political knowledge, not domain-specific information, is the most useful and reliable construct for survey research.
