Further assessment of a method to estimate reliability and validity of qualitative research findings

The purpose is to describe an evaluative strategy for use with qualitative data, a strategy that is a synthesis of quantitative and qualitative assessment methods.

Abstract

The reliability and validity of qualitative research findings are viewed with scepticism by some scientists. This scepticism is derived from the belief that qualitative researchers give insufficient attention to estimating reliability and validity of data, and the differences between quantitative and qualitative methods in assessing data. The danger of this scepticism is that relevant and applicable research findings will not be used. Our purpose is to describe an evaluative strategy for use with qualitative data, a strategy that is a synthesis of quantitative and qualitative assessment methods. Results of the strategy and factors that influence its use are also described.
