H istorically, qualitative research methods have been used with success to develop knowledge in the social sciences. Quantitative and qualitative research is based on different research paradigms that reflect the researcher’s scientific worldview. In current-day practice, qualitative approaches are once again gaining considerable momentum as useful methods for building knowledge in social work and other allied helping professions (Finlay & Ballinger, 2006; Padgett, 2008; Pope & Mays, 2006).

Reliability refers to the degree to which scale produces consistent results, when repeated measurements are made. 21 The nature and purpose of the quantitative and qualitative traditions are also different that it is erroneous to apply the same criteria of worthiness or merit. We argue that qualitative researchers should reclaim responsibility for reliability and validity by implementing verification strategies integral and self-correcting during the conduct of inquiry itself. Instrument: A valid instrument is always reliable. Author content. Verification processes ensure congruence (alignment) among the research questions, published literature, participants, data collection, and analysis Design Implementation Dissemination Methodological coherence = Congruence. Consideration must be given not only to the results of the study but also the rigour of the research. That is, they mean different things to different researchers. Like many concepts in the social sciences, there are referred to as contested terms. Due to this, methodology, methods and results naturally differ accordingly (Goertz & Mahoney, 2012). First, reliability, validity and triangulation as used in case study method are discussed as a way of providing a springboard to examining what these three terms mean. How to ensure validity and reliability in your research.

The concept of reliability is then analysed, establishing the traditional understanding of the term, and evaluating alternative terms. Establishing validity and reliability in qualitative research can be less precise, though participant/member checks, peer evaluation (another researcher checks the researcher’s inferences based on the instrument (Denzin & Lincoln, 2005), and multiple methods (keyword: triangulation), are convincingly used. Evidence Based Nursing, 18, (2): 34-35. Validity and reliability of qualitative research represent the key aspects of the quality of research. Reliability and validity are analogues and are determined differently than in quantitative inquiry. Accordingly, qualitative research has a more difficult task when trying to establish the reliability and validity of its data. Reliability and validity vary with each qualitative approach and according to Creswell and Poth (2018), there is less emphasis on validation for narrative design than on the other qualitative designs.
