To establish the trustworthiness of a study, Lincoln and Guba (1985) use the terms “credibility,” “transferability,” “dependability,” and “conformability” as “the naturalist’s equivalents’ for “internal validity,” “external validity,” “reliability,” and “objectivity”. To operationalize these new terms, they propose techniques such as prolonged engagement in the field and the triangulation of data sources, methods, and investigators to establish credibility. To make sure that the findings are transferable between the researcher and those being studied, detailed descriptions of the cases are necessary. Consistent with all the descriptions above, this study establishes trustworthiness and credibility in that the researchers involve in the prolonged engagement in the sites for about eight months, they use triangulation of the data sources and analysis, and they provide thick description of the phases of the data collection and analysis.
