Grounded theory: a qualitative research methodology for physical therapy

Abstract

The interest in grounded theory methodology for physical therapy research has grown in recent years. Grounded theory is a qualitative research methodology, initially developed by sociologists Barney Glaser and Anselm L. Strauss. Significant variations in the approach were later introduced by Strauss and Corbin. The intent of grounded theory methodology is to generate a theory relating to a particular situation. Other distinguishing features of this method include the use of open-ended questioning, the synthesis of data collection with analysis, the use of theoretical sampling, and the systematic procedures for data collection, analysis, and theory development. The purposes of this article are to introduce the tenets of the grounded theory methodology, to present examples of how the methodology can be applied to physical therapy research, and to suggest criteria for evaluating grounded theory studies.
