In discussing the place of diverse qualitative research within psychological science, we highlight the potential permeability of the quantitative-qualitative boundary and identify different ways of increasing communication between researchers specializing in different methods. Explicating diversity within qualitative research is facilitated, initially, through documenting the range of qualitative data collection and analytic methods available. We then consider the notion of paradigmatic frame and review debates on the current and future positioning of qualitative research within psychological science. In so doing, we argue that the different ways in which the concept of paradigm can be interpreted allows us to challenge the idea that diverse research paradigms are prima facie incommensurate. Further, reviewing the ways in which proponents of qualitative research are seeking to reconfigure the links between paradigms helps us to envisage how communication between research communities can be enhanced. This critical review allows us to systematize possible configurations for research practice in psychology on a continuum of paradigm integration and to specify associated criteria for judging inter-method coherence.
