Qualitative Content Analysis (QCA) is often used in German rehabilitation research. The manuscript shortly describes the evolution of QCA and Mayring's approach to QCA with its 3 varieties: summarizing, explication and structuring, including its general procedural model. Furthermore it deals with the importance of the category system and different forms of category building (deductive vs. inductive). These remarks are supplemented by some thoughts on software use, presentation of results and quantifications. Finally trustworthiness of the analysis and quality criteria for qualitative (content analytic) research proposed by Mayring are discussed.
