internal reliability in qualitative research

In addition to that, it may be that a random technique is specifically suitable to the character of the research. Random sampling can also help to make sure any unknown influences are dispersed equally within the sample. Random sampling of individuals to serve as informants: Even though much qualitative research includes the use of purposive sampling, a random method may eliminate charges associated with investigator bias in the selection of individuals.Usage of well-established research methods: The particular methods utilized, such as the line of questioning pursued in the data collecting sessions and the ways of data analysis, must be derived, where possible, from those that have been successfully applied to previous comparable projects.

For example, the researcher can conduct a pre-exercise interview with participants who meet the criteria.

Peer debriefing: This describes exposing the researcher’s analysis and conclusion to a coworker or other peer on a continuous basis for the development of both design and analysis of the study.

Here individual opinions and experiences could be validated against others and, eventually, a rich picture of the attitudes, needs or behaviour of those under scrutiny could be constructed in line with the contributions of a range of individuals. This is one way of triangulating via data sources. For example, the researcher should conduct a literature review to familiarize herself with the content of the phenomenon under investigation, collect data by means of a focus group interview to get in-depth information. A different type of triangulation may include the use of a wide selection of informants. The usage of triangulation permits the investigator to strive to distinguish true information. It involves evidence from various sources different methods of collecting data and different investigators.

Triangulation: This means the use of multiple referents to draw conclusions.

Continuous observation: Certain situations concerning to the phenomenon under study should be observed over an adequate period of time to spot certain aspects highly relevant to it.

Extended participation: This represents investment of adequate time to learn culture, test for false information, build trust and usually repeating the procedure central to the case study. This can be attained through consultation of appropriate documents and preliminary visits to the companies themselves.

Steps to Improve Credibility in Qualitative Research This stresses the significance of thick description so that the reader has the knowledge on which to base judgment. Theoretical concepts must have generalisability and transferability, which means that concepts must be applicable to other similar situations.

Internal validity is very important in qualitative research, as research workers are able to demonstrate the reality of the individuals through in depth description of the discussion.
