概要	Comparative document analysis is a qualitative research design that systematically examines two or more documents — or document sets — side by side to identify similarities, differences, patterns, and contradictions across contexts, institutions, time periods, or jurisdictions. Drawing on document analysis as a primary method, the comparative dimension adds analytical leverage by allowing the researcher to ask not just what a document says, but how and why it differs from comparable documents elsewhere.	Thematic Analysis (TA) is a qualitative research methodology for identifying, analyzing, and reporting patterns (themes) in qualitative data. Developed systematically by Virginia Braun and Victoria Clarke (2006), TA is flexible and accessible, applicable across diverse theoretical frameworks and data types, making it one of the most widely used qualitative methods in psychology, health research, and social sciences.
