Typically, when speaking of validity, qualitative researchers are referring to research that is credible and trustworthy, i.e., the extent to which one can have confidence in the study's findings (Lincoln & Guba, 1985). Generalizability, a marker of reliability, is typically not a main purpose of qualitative research because the researcher rarely selects a random sample with a goal to generalize to a population or to other settings and groups. Rather, a qualitative researcher's goal is often to understand a unique event or a purposively selected group of individuals. Therefore, when speaking of reliability, qualitative researchers are typically referring to research that is consistent or dependable (Lincoln & Guba, 1985), i.e., the extent to which the findings of the study are consistent with the data that was collected.
